pulled on a pair of boxers in which to sleep and returned to the room. She didn't say a word, merely stepping past into the ensuite after me, and that did little to allay my discomfiture. I got into the bed, reassuring myself that it was, at least, big enough for both of us to sleep without needing to touch one another, and pulled my Kindle out while I waited.
The door to the ensuite opened a few moments later, and she came out wearing just a towel. But rather than walk around to her side of the bed, she came to mine. I looked up in surprise.
"What are you doing?" I asked, as her hands went to the knot of the towel, unfastening it.
"Finishing our date," she said, and let it drop. She was, of course, perfectly naked beneath it.
My breath caught in my throat as I looked at her, and she was so close to me I could see every part of her. She took my hand in hers, and, while my mind fought to catch up with the sudden speed of events, she brought it to her breast, laying my palm over her nipple.
"I said you could squeeze my breasts if you took me on this trip," she said, holding my palm to her body.
"We can't do this," I groaned, even as my hand clenched on her breast of its own accord.
"And I promised you a blowjob," she said, pulling the sheet back, until I lay exposed before her in just my boxers. My cock twitched at her words, even as my hand squeezed her breast again.
"You don't need to do that. That was just the date."
"The date hasn't finished yet."
"This is wrong."
"So you keep saying," she said, climbing onto the bed and swinging her knee over to sit astride my hips. I looked up at her, kneeling naked over me, her thighs spread wide, her body open to my gaze. Her fingers slipped beneath the waistband of my boxers, and I didn't resist. I couldn't.
She moved lower down the bed, watching me all the while, and I realized I'd spread my legs for her. It was either that or have her sit on them, but now she was between them, her face close to my groin. I felt my cock twitch in anticipation.
"If you still think this is wrong afterwards -- or, if you didn't like it -- you can punish me," she said, leaning forward and placing a lick across my lower abdomen. "You could pin me helpless across your lap," her tongue trailed down, as she pulled my boxers lower, and my cock sprang free. I groaned in torment and arousal, held by her words as much as by her touch on me. "You could spank me, as much as you wanted." She placed a kiss on the tip of my cock, and her small hand closed firmly around the base of me. "I won't resist," she whispered, and I felt her breath on my skin. "I won't try to stop you." She licked upward from the base to the very tip, slowly, watching me as she did so, my cock half obscuring her face as she knelt between my legs and held it in one hand. "I won't judge you, if you enjoy it too," she paused to swirl her tongue around the tip of me, and again I groaned. She held my cock pressed to her face as she murmured, "I won't judge you if you enjoyed spanking your little sister, if you wanted to hurt me and make me cry out beneath your hand."
Her mouth came over my cock, sinking down my shaft, swallowing me as she pushed lower still, until I felt her throat opening to me, and still she pushed lower. She had me so aroused with her words and her touch, and now her mouth on me -- the first mouth I'd ever had on me -- that I knew I wouldn't last long. I wanted to pull her off, to stop her, but I couldn't; I was too weak. This was all wrong, and I knew that too, but that didn't stop me losing myself in the feel of her mouth, and she slowly rose up over me, licking and sucking as she did so.
She paused at the top, swirling her tongue around my cock head again as she met my eyes with hers, and her expression was one of such lust, such hunger, that I about came right then. She sank down again onto me, and it was only through sheer will that I was able to hold on for a few moments longer as she bobbed on my cock, sucking and licking, her hand sliding up and down my shaft even as she did so. Then it became a fight not to come, just to prolong one of the best experiences of my life, and yet all too soon I felt my orgasm arriving, my cock twitching as I spurted rope after rope of cum into my sister's waiting mouth.
I groaned as I lost myself in my orgasm, her tongue lapping at me even as I filled her mouth, and I felt her swallow around me as she took the mouthful of cum I'd given her into her body. I threw one arm over my face, lying stretched open and naked before my sister, my cock still in her mouth, and almost immediately I felt an overwhelming sense of guilt. What had I done? I'd come in my sister's mouth, I'd let her give me a blowjob. She'd wanted to, dammit, and I'd let it happen. Why had she wanted to? It made no sense; I was her brother. Yet I couldn't deny it had been one of the best orgasms I'd ever had.
I reached down and pushed her away, pulling my boxers back up over my still-hard cock, slick with my sister's saliva. Fuck, I was so going to hell. Or I was if I believed such things; I had to take a moment to remind myself I was an atheist. Still, there was no justification for what I'd done. What we'd done.
"You need to stop," I said, feeling like an ass even as I pushed her away. I'd just let her give me a blowjob, just come in her mouth, and now I was pushing her away.
She didn't argue. She didn't complain, or say something perfectly justified like, 'You weren't objecting five minutes ago'. She just stretched out on her side of the bed and pulled the sheet back up over us.
I reached out and turned the light off, as though the darkness would help. It didn't.
"Are you going to sleep naked?" I asked, after some moments. Way to go, Alex, still being the ungrateful asshole.
Again she didn't say anything, she merely leaned down to her bag beside the bed, rummaged around for a moment and pulled out a t-shirt, slipping it over her head. "Is that okay?" she asked me. When I didn't answer, she lay back down again on her side, facing away from me.
For some time we lay there, not touching in the bed, and I hadn't moved since she'd finished. Still on my back, one arm still over my face, full of recrimination, guilt, and self-loathing.
"Did you like it?" she murmured in the darkness.
I couldn't answer that, not without acknowledging that what we'd done had felt so good, even though it was so wrong.
I don't know if she understood, or whether she was angry with me, but she didn't try and say anything else.
It was a long time until sleep came.
*
I awoke as our room filled with morning light.
It took me a moment to remember where I was and why things felt different, to realize that I was in bed with my sister, and not only that, but during the night we'd moved together. I was spooning her, she was pressed back against me, and her ass was against my crotch.
I had morning wood. Boxers or no boxers, there was no hiding that, and my erection was pushed firmly against her ass. More than that, my arm was around her, and in my sleep I'd clearly found it perfectly natural to cup her breast.
Perhaps she'd maneuvered herself there, at some point during the night. Perhaps she'd even taken my hand and placed it on her breast. After the way she'd been, I wouldn't have put it past her. But there was no denying the position we were now in. I was fully awake, all ready to disengage myself before she woke to find us in such a compromising position, yet her body twitched and instead I held still, catching my breath.
Her t-shirt had ridden up, and I could feel her bare ass pushing back against me. My cock was nestled between the cheeks of her ass, barely constrained by the soft cotton of my boxers. I slowly came to realize that her arm was extended down her body, beneath my arm, her hand between her legs, and she wasn't as asleep as I'd first thought. Or if she was, she was having one hell of a dream.
Her hand was working between her legs, and the twitches that I'd felt were her body responding to her own touch. Perhaps it hadn't been the morning light that had woken me, perhaps it had been her pleasuring herself.
I knew I should make a noise, or roll away, or at least take my hand from her breast and my erection from against her naked ass. But I didn't. After the night before it seemed like it hardly mattered anymore. So I stayed perfectly still, breathing lightly and evenly, feeling every sensation in my sister's body as she slowly thrummed herself to her own release. Her hips began to twitch against mine, her ass rubbing against my hardness, until it became obvious that she was making no attempt to hide what she was doing, and that meant that either she didn't care, or she knew I was awake. By that point it seemed too late to object, and anyway it was only a moment or two until her body tensed, and she reached her own climax with an explosive little sigh.
"Good morning," I said, giving her breast a squeeze.
"Nice way to wake up," she replied, rolling onto her back as I made room for her.
She reached up with her hand and ran her fingers over my chest, and it was only then that I realized it was the hand that had been between her legs, and she'd trailed the residue of her pleasure across my nipple. She was looking at me mischievously in the morning light.
"Was that the wrong thing to do?" she said, in mock-concern. "You can spank me if you think I deserve it."
"You definitely deserve it," I said, "but I'm not going to spank you."
"Aww," she pouted. Her hand slid lower, and she ran a fingertip over the ridged hardness in my boxers. "Is that for me?"
Difficult question to answer. I supposed I could argue it was just biology, but when I woke up pressed against my half-naked sister, my hand on her breast and my cock pressed between her ass cheeks, there was a good chance she'd had something to do with it. "Maybe."
"Can I see it then?"
Somehow, I knew she was going to ask that. I squirmed uncomfortably. This was so wrong, but she wasn't going to let up. "Emma, I --"
She turned to her side, pressing one barely-covered and warm breast against me. "You just watched me masturbate, didn't you?"
"...Yes."
"Then I get to do the same."
Her fingers were toying with the waistband of my boxers, but it was her playful smile that held my gaze. I couldn't help but agree that I wanted some release, and lying in bed with a semi-naked girl pressing her body against me didn't help that any.
She took my hesitation as an opportunity to inch closer, her lips against my ear. "Unless you want me to do it for you," she whispered.
I didn't know why I was still resisting, except that I couldn't shed the feeling that it was wrong. It kept coming back to one simple point: she was my sister.
But I'd waited too long. Her hand slid inside my boxers, grasping my hardness.
"Stop, please," I groaned.
"It's just masturbating, Big Bro," she murmured. "Everyone does it. Natural thing to do first thing in the morning."
Her hand slipped away, which was both a relief and a disappointment, and I watched as she rolled onto her back beside me in the bed. The t-shirt she was wearing wasn't that long, and it had already ridden up some. Her hand slipped down beneath the hem, and her legs spread as she began to touch herself again.
"Do it with me," she said, her voice breathy, and her words were so quiet I hardly heard them. But there were no other sounds in the room; nothing save for her breathing and my heartbeat thudding in my chest.
"Please," she begged, as her other hand came up to her breast as I watched, "I want to see you..." she rubbed the ball of her thumb over her nipple, stiff beneath the thin t-shirt, and her legs parted a little more, pushing against mine, "...touch yourself."
"You're my sister," I groaned, clinging on as best I could do what shreds of decency remained. I feared so many of them had already fallen by the wayside.
"And you're my brother," she whispered, shuddering with pleasure as she uttered the words. Was it the words that had thrilled her, or the touch between her legs at that particular moment? "What's the harm? It's not like I'm asking you to..." she moaned softly, "fuck... me..."
I knew I should put a stop to this before it got even further out of control, but I didn't have the strength to even suggest it. Giving her what she wanted seemed the easier option, and it was what I wanted too. At least, I told myself, if we masturbated together, we'd only be doing that. We wouldn't be fucking.
I slid my hand inside my boxers, pushing the material down and freeing my hardness.
She didn't say anything but her eyes were on my hand, and we lay there together, touching ourselves, our bodies pressed together from thigh to shoulder. Her fingers were moving only slowly between her legs, as though she was stimulating herself more than actively seeking her own release, but then she had come but moments before. My hand was moving much more enthusiastically as I gave in to the desires I was feeling, my own needs. Maybe she was right, maybe there was nothing wrong with this. We were simply sharing a bed and seeing to our own desires at the same time. It wasn't as if we were touching... aside from our bodies, pressed against each other. But I liked the warm feel of her against me, the way she moved slightly while she teasing herself.
"Are you going to... come?" she breathed, watching me.
"...Yes," I grunted, knowing my orgasm was close.
"Good," she said. "I want to see you make a mess. I want to see you spurt your seed up all over yourself."
I groaned at her words, my fist becoming a blur as it worked my shaft.
"Come for me," she moaned, her own fingers moving swiftly between her legs. "Come now."
I grunted as my cock pulsed, shooting ropes of cum up into the air to land with a splash across my chest. Beside me, her moans reached their own high note as her fingers rubbed furiously between her legs, and I knew she was coming again as she watched me. That she'd timed her own orgasm to match mine sent a tremor through my body, and another spurt of cum flew from my cock.
"Yes..." she moaned, watching, her legs spread wide as she pleasured herself. She let out a long, shuddering breath, relaxing beside me, and it seemed to echo mine as my own orgasm slowly subsided. We lay together, side by side, my body covered in the signs of my orgasm. She, at least, had managed a less messy conclusion. Sometimes it didn't seem fair all the advantages girls got -- less mess when they came, no embarrassing erections to hide, the ability for multiple orgasms -- whereas I was covered in my own cum. I supposed men had advantages women lacked, but the multiple orgasms thing seemed, overall, to weight it heavily in their favor.
"That was hot," she announced, and then reached over to dabble her fingers through some of the cum on my chest, lifting her hand to her mouth and licking them clean. "You taste nice, Big Bro."
She'd swallowed all my cum last night, and was tasting it again this morning. It was more than I'd ever managed with Penny Dalglish, that was for sure -- and this was my sister. Fuck, this was some kinky shit.
"I need a shower," I said, getting up.
"Want me to come wash you?" she asked, stretching slowly as she did. Her t-shirt had ridden up and her legs were still spread, her pussy was wet and open before me. I suddenly knew that I could touch her, and she wouldn't object; hell, she'd probably moan and push her hips against my hand. I could probably even fuck her and she wouldn't object. She'd let me. Perhaps she even wanted me to. My sister was a slut, but fuck if she wasn't the hottest thing I'd ever woken up next to.
"No, I'll do it," I said, walking off without looking back. I didn't trust my self-control if we were naked in the shower together.
I stood under the spray, washing the remnants of my cum off my body, and reflected on our relationship. It was clear that Em was prepared to cross lines all over the place, but to what end? What were her reasons, or her motivations? Half of me expected her to stop at any point, yell 'Tricked you!', and reveal she'd been filming the whole thing. The other half felt like she'd let me do whatever I wanted to her, especially if I spanked her first.
And that didn't help with what I felt, which I still wasn't clear on. The refrain 'she is my sister' was growing weary in my head, and I could feel my barriers being slowly worn down. Hell, we were both adults, and no one knew us here. We were in the privacy of our own room, too, with no chance that someone might disturb us. Were these morally indefensible justifications? Or was I merely coming around to Emma's way of thinking, one reluctant step at a time?
I killed the shower and used a towel, only then realizing that the only clothes I had in here were already dirty. I tied a towel around my waist and opened the door, and Emma was where I'd left her, lying half-naked on the bed. The shirt was still up around her waist.
"Mmm, hot look, Big Bro," she said. I stopped and gazed at her revealed nakedness, thinking the same.
She rose smoothly, smiling when she saw me looking, cat-like in her grace, and padded past me. As she did, she grasped the hem of her t-shirt, pulling it over her head and flinging it casually onto her bag. I was almost getting used to her displays of casual nudity. Almost. Didn't mean I wasn't going to look, though. Have I mentioned how hot she is?
I heard her run the shower and a moment later the sound of water spraying down on her body. She hadn't closed the door; it was ajar, unlocked. One might even call it an invitation.
Shaking my head, I fished out a clean pair of boxers and lay down on the bed, pulling the sheet over my lap and bringing up my Kindle. There was only so much of my sister's sexuality I could take before I crumbled, and my defenses seemed to be the only thing stopping us from doing things we really, really shouldn't.
She padded out naked a few minutes later.
"Gonna go look around the convention. Do you want to come?" she said, as she fished for clothes through her bag. I tried not to stare.
"Er... not really my thing, Sis. I'll probably hang around here, or maybe go for a walk."
"You sure you'll be okay?" She'd pulled out a pastel pink outfit that seemed far too small to wear in public. But then, I guess it suited the theme of the convention.
"I'll be fine." I'd be fucking bored, but what else was there to do? Take a trip into Boston, I supposed, but it seemed a lot of effort.
"Well, it's the last day," she said, as she stepped into a pair of lacy white panties. "So I want to get as much done as I can." A matching white bra followed, with a white crop top and then the pink outfit -- skirt and jacket, both very, very short. She looked innocent, demure, and kinky all at once. It was fucking hot.
"You be careful not to get the wrong attention dressed like that," I muttered.
She smiled at me as she sat on the chair and laced up her matching pink platforms. "It's okay, Big Bro. It's a public event, security everywhere, I won't be leaving the building and, besides, the only person who gets to play with me is you."
I cleared my throat awkwardly. "Just... be careful."
"Sure. Back when it finishes? Probably about six."
"Sure." I glanced at the clock; it was only just after nine. Maybe I'd go find some breakfast.
"I'll leave you the room key," she said, then paused at the door and glanced back at me. "Gotta say, tough to leave you, lying mostly-naked in the bed." She made a mock sigh. "Still, a girl's gotta do what a girl came to do."
She smiled at me and slipped out the door, closing it behind her. went down for breakfast. Mooched around a while. Went for a bit of a walk, got bored. Went back to my room. Read for a bit. Glanced at the clock: almost two. Still another four hours until Em would be done, and I'd left it too late to go off into Boston.
Could take a nap, I supposed, but I didn't really feel like doing that.
There was a knock on the door while I was still figuring out what to do.
I'd taken a shower when I came back in, and was only wearing boxers and a t-shirt. Hell, even with the AC it wasn't cold in the room, and I'd had no reason to get dressed. But I couldn't exactly answer the door in boxers.
I compromised by opening the door a crack, keeping myself behind it, then opened it wider as I saw it was Emma. "Here for a break?" I asked, letting her in.
"Here for good," she said, as she entered. I closed the door behind her, raising an eyebrow at her back.
"I thought you were all into this thing."
"Yeah, so did I," she said, as she bent to unstrap her platform sandals, giving me a fair view of her ass as she did. "But to be honest, Big Bro, I think I've outgrown it."
I chuckled. "No shit. I could've told you that before we left."
She straightened, turning to face me. "Well, you were right. But I wanted to get away, and then I wanted to be alone with you, so the trip isn't a complete waste, is it?" She pulled the pink jacket off and dropped it on her bag.
"No, I suppose not," I agreed as I walked back to the chair I'd been sitting in, though I wondered what I was agreeing to.
"Gonna take a shower," she said, drawing my eyes to her again. She was unfastening the pink skirt and letting it fall. "Need to wash that convention off of me, and my feet are fucking killing me."
I watched, saying nothing, as she pulled her crop top off, leaving her in just her underwear. I knew damn well that she'd been walking around the convention, looking like that, getting about a million stares and yet it was me, her brother, that got to see her take it all off. I mean, fuck.
"Sure," I said, nonchalantly. I'd watched her strip a few times now, but if she wanted to show me again, who was I to argue?
She reached behind her back, unclasping her bra, and let it fall.
"You do have amazing breasts," I said. Fuck, how did that slip out?
She looked at me in surprise, then smiled. "Do you really think so?" she asked, pulling her shoulders back to better show them to me.
Well, I'd said it now. It was too late to take it back. Besides, it was true.
"Abso-fucking-lutely," I said. "Your breasts are perfection."
She smiled again and turned away. "What about my ass?" she asked, pushing it out slightly for my inspection.
"That too." It was funny how only a couple days before I would've felt awkward even looking at her ass, but now I was okay discussing it with her. Like it was a piece of art, or something. Well, it was a piece of art. Beautiful, living art.
She looked at me over her shoulder. "Ass, or breasts?"
"How do you expect me to tell when one is bare and the other is clothed?" I couldn't believe I'd said that, either. I half expected her to accuse me of being some kinda pervert, but she merely chuckled, a deep, throaty chuckle.
"Very fair, but I'm going to take a shower, first. Then you can examine all of me to your heart's content."
She padded off into the bathroom, closing the door this time, and I stared blankly at my Kindle a while. I couldn't help but think that the dynamic had subtly changed, that some degree of acceptance had arisen. More on my part than hers, for she had always been open to this. At least, it seemed she had. I found myself wondering where that had stemmed from, and by the time the ensuite door opened again, I thought I had my answer.
She came out wearing just a towel, wrapped around her tightly.
"I have a question," I said, before she had a chance to say anything.
"Okay. Truth or Dare, then," she announced playfully, coming over to take the chair opposite mine, and tucking the towel demurely around her thighs as she carefully sat.
I cocked my head, looking at her. "Sounds dangerous."
"Probably."
"Is that you starting with a Truth?"
She inclined her head gracefully, "I will allow your question."
"Most kind," I said, drolly. "I was thinking, while you were out. Wondering when all this..." I made a gesture with my hand that covered not only the room but the scantily-clad form of my slutty little sister, "...started. Was it when I spanked you the first time, over you trying to steal my car?"
"Borrow," she said with a playful smile. "Yes, I suppose you could say that. I... I liked it when you spanked me. It showed me a side to you I didn't know existed. I like your dominance, Big Brother." She smiled at me a moment. "My turn. Truth or Dare?"
"Truth."
"I knew you'd say that. So tell me truthfully: did you like spanking me?"
The time for denial was long past. She already knew the answer anyway. "Yes, I did. Why do you like being spanked?"
"Don't I get to choose Truth or Dare?"
"Not this time."
She smiled again, then looked thoughtful. "Um... I like the dominance, as I've said. And I like the intimacy, and sensuality of it. It turns me on. And I like the feel of your hand on my ass."
It made a lot of sense when she explained it like that. I realized I'd maybe been hasty when I'd accused her of being fucked-up for liking it. Besides, lots of people liked it -- and lots of people liked weirder things than that, too.
"I'm sorry I called you fucked-up for liking it when I spanked you."
"I'm sorry I never called you fucked-up for liking spanking me," she replied, her lips twitching in amusement.
I laughed. "Fair. And I deserved that. But you pushed me into it, didn't you? The second time?"
She nodded. "I did. I wanted to know if you'd do it again, or if it was a fluke. But it's my turn. Truth or Dare?"
"Truth." I'd let her take the first dare. I knew I wouldn't have to wait long.
"Did it turn you on? Spanking me, I mean?"
I smiled, conceding the point. "Yes, it did. And again, you're right; I shouldn't have judged."
She shook her head. "Not what I meant. I just wanted to know. I'm glad it turned you on." She raised one eyebrow. "I'll take a dare."
"You've already shown me your breasts. I dare you to show me your ass."
"Easy. How long?"
Oh yeah. People usually put timers on these things when they played. I'd never actually played Truth or Dare before... not like this, anyway. "Er... thirty seconds?"
She reached for her phone and set a timer, her lips twitching in amusement as she did so. It was a dangerously playful expression. I wondered what I'd unleashed... and then I realized that of all the people in this hotel, it was me that was going to be the only one to enjoy it.
Then she stood, still in her towel. For some reason I thought she'd dump the towel, given how quick she'd been to be nude at other times, but now that we were playing, she seemed to want to make the most of it. That was okay by me. She turned away, leaning forward to support herself on the chair, sticking her ass out toward me, then reached back and slowly inched up the towel.
Bit by luscious bit, her fantastic ass came into view, until the towel was so high it was up over her waist. I feasted my eyes on the delightful curve of her derriere, the intriguing slit that ran between her cheeks, and the hint of her perfectly smooth pussy that I could just see below. Then her phone bleeped, and the towel dropped down again, covering the beauty that she had so briefly shared with me.
"It is a fantastic ass," I conceded.
"So, ass or breasts?" she asked, sitting back down in her chair.
"Ass. Has to be ass. I love your breasts too, but your ass is to die for."
She giggled. "My brother is an ass-man. I never knew that before. Truth or Dare?"
"Dare, then, I suppose." I had no idea what she'd ask of me, only that the game called for a dare.
"Take your t-shirt off."
I raised an eyebrow at the simplicity of her request, but leant forward and pulled it off, bundling it up and throwing it over on top of my bag. "Is the lady so easily pleased?"
"I like seeing you naked," she said, running her eyes over me.
I didn't understand her interest, but I wasn't going to complain. It also told me what she'd ask for next, and that I decided to postpone a little longer.
"Your turn."
"I'm okay with another Dare."
I'd figured she would be. The obvious choice, after the t-shirt thing, was to get her to lose the towel. But I didn't want to be so predictable. "I dare you to masturbate in front of me, for one minute. Without coming."
"Mmm, I like it," she purred. She slipped a hand down between her legs, raising one thigh so that I couldn't see what she was doing. "Are you going to time me?"
"Yes. Are you going to let me see?"
"No. Wasn't part of the dare."
Dammit. I'd have to be more specific in future.
She kept her gaze on me as her hand began to move between her legs, her eyes smoky with the heat of her gaze, and though it was her putting on the show, it was me that squirmed awkwardly in my seat. It was intensely intimate, watching her do this, just in front of me. My own sister, masturbating before me because I'd dared her to.
She chewed her lip and her eyes fluttered closed; she opened them with an act of will, trying to hold my gaze as her pleasure grew. Now it was her beginning to squirm, her hips moving beneath her hand.
"I didn't think it was going to be a problem, not coming within the minute," she said around soft gasps, "but with you watching me... fuck, Alex, this is intense."
Her face was reflecting all sorts of emotions now, and her lower lip was beginning to tremble with the passion she was feeling. She began to chew it again, even as a moan escaped.
I glanced down at the stopwatch I'd started on my phone, as the seconds counted into the fifties. I supposed I should let her know, but it was so much fun to watch -- and besides, I liked the idea of her having to edge for me. A minute came and went, and I kept my gaze on her face. Her breath began to come in pants, and her hips were twitching with each touch of her finger.
"Time," I said softly, at about a minute twenty.
She slumped in the chair with a small gasp, then shared a small smile with me. "That was hot."
"You're hot."
Her smile widened, and she lifted her hand to her mouth, slowly sucking her fingers clean of her own arousal as she held my eyes with hers.
"Don't you usually wipe your fingers on my chest?"
She giggled. "I couldn't resist, that time. Truth or Dare?"
"I'll take another Truth," I said, determined to keep my boxers on for a few more minutes. There was an inevitability to them coming off if we kept playing. If they came off now, she'd know she'd made me hard.
"Hmm, a Truth," she said, contemplatively, tapping her fingertips against her chin for a moment. "Are you looking forward to spanking me again?"
My lips twitched in amusement. "You make this too easy. First the shirt, now this. Yes, I am. You know I am."
"Yes," she said, "I know you are. My turn for a Truth."
I cocked my head on one side and regarded her. "What wouldn't you do for me?"
She lowered her eyes, but a playful smile flirted with her lips. "I thought you knew that by now too, Big Bro. There's nothing I wouldn't do for you."
"Especially if I spanked you first, huh?"
She smiled. "Yes, especially then. But I've already promised I'd obey you."
"Why?" I asked, and in that moment, it was the only Truth that mattered, turns be damned.
She knew it too. "Because I love you, Alex. I've always loved you, and then you went and spanked me, and just like that my love became lust, too." Her voice was soft, and I could hear the earnestness in her tone. "I'd always have done anything for you, but since you pinned me down and showed me how you could dominate me, I wanted to do anything for you."
"That was why you stripped your bikini in the kitchen, why you let me into your room while you were naked, and why you showed me your body in my room," I said, finally realizing. "You were basically... offering yourself?"
"Yes," she said, then chewed her lip nervously, fiddling with the hem of her towel. I could see the sudden awkwardness in her body language, her fear I would reject her, but I didn't want to say anything yet. I thought there was more to come. The seconds ticked slowly by before she at last spoke again. "I wanted to give you everything I had, but you seemed to see me only as your sister. I knew that you'd have to see me as a woman, first. So, I... I showed you my body. I... I hoped you'd like it, that maybe you'd want it."
I'd already told her she had amazing breasts and a fantastic ass, and yet she was still showing signs of self-consciousness, still needing affirmation. But then, was I any different? I didn't believe her, either, when she told me that I was a 'hunk'. Perhaps it's in all our natures not to believe what we most want to hear.
"So you're my little slut sister," I said, watching her.
"Yes," she said, nodding her head, her eyes wide and full of hope as she looked at me.
"You'll do whatever I tell you to?"
"Anything you want," she breathed, her fingers toying nervously with the towel.
"Suck my cock?"
"Whenever you tell me to," she said, licking her lips. Her eyes flicked down involuntarily toward my boxers.
"Present your bare ass for a spanking?"
"Oh god, Alex..." she shuddered at my words. I took that as a 'yes'.
There was one more thing I needed to know. "Let me fuck you?" I held my breath.
"Fuck yes. Any hole you want," she said.
Those four words speared straight through me, almost as if my heart had stopped. Any hole you want. Fuck, I'd only dreamt that a girl would ever say those words to me, and that it was Emma? My sister? It was too perfect. She was my slut sister, she loved me, and she'd do literally anything for me.
"Stand up," I said, my voice as neutral as I could make it as I tried to hide the lust I was feeling.
"Yes, Alex," she said, rising swiftly.
"You don't need the towel anymore."
"Sorry." She pulled it free and let it drop to the chair behind her, then clasped her hands behind her back and stood, perfectly naked, before me. There were no games now.
"I trust you know this behaviour is totally unacceptable," I said, keeping my voice as stern as I could.
She quailed before me, her eyes falling to the floor. "I'm sorry," she whispered. "I just wanted..."
"Quiet," I said, cutting across her. "You're going to have to be punished. Go to the bed; it's time for your spanking."
Her head came up swiftly, her eyes finding mine, the hope blossoming again. "Yes, Alex."
I watched her ass as she walked to the bed. Her slender back narrowed to the most delicate of waists, then flared out over the curve of her hips; two almost perfect halves split by the enticing crack that ran all the way down to the gap at the top of her thighs. I rose from my chair, and as she stopped at the side of the bed, unsure exactly what I wanted from her, I stepped up behind her.
"Bend for me," I said, my hand in the small of her back.
She bent forward over the bed, her smooth skin sliding beneath my palm, her ass coming up as if in offering. She rested her body on her elbows, keeping her legs straight, all the better to present her charms to me. I let my fingers trail down over the top of her ass.
"You know you need a spanking, don't you?"
"Yes, Alex," she murmured into the bed.
"I warned you not to make a third time necessary." I placed my palm against her rump, letting my fingertips push into the delightful delve between her cheeks.
"I'm sorry," she said, and her voice carried a delicious sense of real vulnerability.
"I'm going to have to punish you much more than before," I said, as I pulled one cheek away from the other. "It's for your own good. To show you your place."
"Whatever you wish to do to me, Big Bro," she murmured. "Anything you wish to do to me."
My first blow landed with a satisfying crack against the curve of her ass, and the gasp it pulled from her was even more satisfying still.
"Do you wish me to hurt you?" I asked, genuinely curious how far she wanted me to take it. I didn't wait for her reply before my second strike landed on her other cheek, at least as hard as the first.
She cried out softly. "You can hurt me if you want to."
I struck her again, twice, alternating cheeks, each crack sounding sharp through our hotel room. "I know I can. That isn't what I asked you."
She was gasping from the last blows. "Please don't hurt me too much."
"But some?" I trailed my fingers down over her ass, feeling the heat in her skin. She shivered at my touch.
"Yes, some."
"Enough to know that you are mine?" I dug my fingertips into the flesh of one cheek, spreading her ass open. I had been standing beside her, looking down on her, but now I wanted to see all she had to offer. Still holding one cheek in my grip, I moved slightly behind her, and now nothing obscured my view of her body's most intimate parts.
"Yes, I am yours. I already know I am yours. Hurt me as much as you wish to. Do whatever you wish with me."
I chuckled softly, even as I ran my eyes down over the intimacy of her tight, puckered asshole. "I bet you are already wet, aren't you my little slut?"
"Yes, Alex," she whimpered into the bed.
"Ready to be penetrated."
She whimpered again. "Yes, Alex."
"Show me. On the bed, on your back."
She moved swiftly, with an alacrity that the blows to her ass must be partly responsible for, even though I'd hardly spanked her compared to the other times. But I wasn't done yet.
I loved the expression she wore as she looked up at me. Pure submission in her gaze. Was that the spanking, or the natural predilection of my sister? I thought back to her acquiescence the last two times I had spanked her.
"You like being told what to do, don't you?"
"Yes, Alex." The heat in her gaze made my cock twitch.
"Lie here," I said, indicating the edge of the bed. I wanted her beneath both my hands.
It was fun to move her around, to be able to cast my eyes over her nakedness without worrying that she might object. I realised that at some point I'd set down my own hang ups; at some level this was still wrong - she was my sister, after all - but also it was the consensual acts of two adults, alone in a hotel room. She wanted me to do whatever I wished with her; would it not be churlish to refuse?
I waited until she was lying on her back immediately before me, And let my hand rest lightly on her shoulder. "Knees up to your chest, spread your thighs."
She obeyed with the speed and enthusiasm that showed her willingness, and now her body was fully opened before me. I trailed my fingers down over her breast, flicking a fingertip across her nipple, but my eyes were between her legs, my gaze caressing her bare folds as they glistened with her arousal.
I lifted my other hand and lightly let my fingertips rest on her open pussy. She chewed her lip nervously, staring up at me with wide eyes. It was obvious how wet she was even from that slight touch.
"Should I punish you more?"
She opened her mouth as if to speak but no words came out. Instead she just looked at me, as if not knowing how to respond. It was kind of cute.
"I'll take that as a yes," I said, and then slapped my fingers down across her vulva. The gasp she rewarded me with was a higher pitch than the ones I'd heard before. "Did you like that?" I asked, as I took her nipple between finger and thumb and pulled it, twisting slightly as I did.
"Please don't make me answer that, Alex," she pleaded with me.
Yet that was an answer in its own right. If she hadn't liked it she simply would have said no, so clearly she had. It was interesting that she couldn't bring herself to admit that to me - or, possibly, to herself.
"If you're not sure," I said, "let's try it again."
I let the words sink in, the realisation in her eyes, before I again slapped my fingers against her pussy. Harder than before. And this time I let them linger, slipping through her slick folds. Her gasp quickly became a moan and her hips twitched on the bed.
"Seems to me that you like it," I said, as I pressed my palm into her breast and rubbed my fingers through her wetness. Still she didn't say anything, but I wanted to hear her. I took her nipple between finger and thumb again, twisting and rotating it as I pulled it up from her breast, "You liked it didn't you?"
"Yes, Alex," she gasped.
"You like it when I hurt you, don't you?" I pulled her nipple harder, her delicious breast stretching out as I did so.
"Yes, Alex," she said, and it was barely more than a whimper.
I smiled, and bought my fingers down again in a slap across her exposed cunt. She hadn't once tried to stop me, or to close her legs. She cried out softly, but her eyes when she looked up at me showed only arousal and submission.
My sister was truly my toy to do with as I wished.
I let my hand linger, and this time - for the first time - I slowly slid a finger inside her. I felt the tightness of her pussy around my digit, the slick silky wetness of her walls, but it was her face I watched as I penetrated her, and the little 'oh' sound she made was sweet music to my ears.
"My little masochist," I murmured to her.
"Your little toy," she replied, and it made me smile that she'd used exactly the word I'd thought a moment previously.
"I want to watch you fuck my finger," I said. "Buck your hips up against my hand. Fuck yourself against it."
She began to do as I told her, her hips rocking against my hand. I'd never seen anything in my life hotter than my sister, lying naked on her back, her knees up and her thighs apart, humping herself up against my fingers.
I let my thumb brush against her clit, and was immediately awarded with another moan. I walked around the end of the bed, now having to stretch over her to keep my hand between her legs, and as I walked I pushed my boxes down, freeing my cock. She watched me all the while, her chin coming up slightly to keep me in her view, and she even licked her lips in anticipation. She knew exactly what I had in mind, and I didn't intend to disappoint her.
I pushed the head of my cock against her lips and she opened her mouth hungrily. In this position it was easy to push in against her throat, immediately filling her mouth, and it took a surprising amount of my self-control not to immediately start face-fucking her as hard as I could. Though, knowing her, she probably wouldn't have objected. She probably would have liked it.
"Would you like me to fuck your face?"
She couldn't reply, of course, but the deep moan she gave me around my cock in her mouth was still a clear answer, as was the hunger in her gaze. Well, fair enough then. I gripped her pussy with one hand, the other clutching her breast, and so held, so supported, I began to drive my hips forcefully against her mouth. Fuck, but my sister was a kinky little submissive slut, and she clearly liked being treated rough.
For some time I used her in this way, listening to the sounds of her throat glrrrking around my cock as I fucked it, and seeing the tears build up in her eyes. When I thought she needed respite, I pulled my cock from her mouth, slick with her saliva, and let it fall across her face. And she didn't need telling; unbidden she raised her chin slightly, angling her head until she could reach my balls with her tongue, and proceeded to lick and bathe them, worshipping me with her mouth.
I think that was the moment that made me realize there was no turning back. We'd never merely be brother and sister again, after this. Our relationship had a whole new level to it now, and I intended to make the most of it.
"On your knees, Sis," I said. "Give me your pussy."
"Yes, Alex," she murmured under me, placing a last kiss on my cock before moving from beneath my hands.
I watched as she moved to all fours, lowering to her elbows and raising her ass in the air for me, her thighs spread wide to support herself, and both her holes on offer. I knew I'd take her ass soon enough, but for now I wanted to be inside her warm wetness.
I took my cock in my hand and lined myself against her entrance, pushing in slowly as she held herself for me. We both moaned together as I penetrated her; the culmination of what we'd been building to for what seemed like days, now, and I kicked myself that I'd waited as long as I had. What wasted time. But it didn't matter; we were here now, and I was inside my sister. She felt fucking amazing around my cock.
I reached forward and wrapped her hair around my fist, pulling her head back as I thrust into her. She arched her back, her head coming up with a gasp, and I smiled at the view I had. I was treating her like the slut she was, and I was happy to do so. It was fucking hot as far as I was concerned, but too, I knew she was getting off on. That was the most amazing thing -- everything she wanted to offer me, I wanted to take; everything I wanted to take, she was only too pleased to offer me.
Was that because she was my sister? Did that explain the extent of our compatibility?
I put aside the introspection and gripped harder in her hair, driving my hips forward against her ass. Her pussy clenched around me as I drove into her, her ass pushed back against my hips, and her whimpers echoed with every thrust.
"Do you like this, sister of mine?"
"You know I do, Big Bro," she gasped.
"Is this what you wanted?"
"Yes... more, please."
I chuckled wryly, and pulled back on her hair. Her back arched and with a gasp her head came up. I slid my other hand beneath her chin and held her to me as I fucked her. She was kneeling up now, her face upturned toward me, and I bent to kiss her as I continued to take her. She moaned into my mouth, her eyes shut tight with the intensity of the experience, and I felt her pussy clench around me as she began to come. She made cute little noises over and over, each thrust into her eliciting a new sound, and I tightened my grip on her as I made her mine.
"Oh, fuck, Alex," she gasped, when her first orgasm finally abated enough her to speak again, and I pushed her forward onto the bed, slipping from her as I did so.
She lay limp, like a rag doll, her body covered in a sheen of sweat and her pussy gaping where I'd fucked her. She always looked hot, but that was a vision I wanted to capture forever. It was tough to walk away from her, but I had something I needed to fetch.
"Stay right there, little slut."
"Yes, Alex," she said, watching me over her shoulder as I kicked off my boxers then walked naked into the ensuite. I was back a moment later with what I needed.
I climbed onto the bed and over her, giving her bare ass a spank as I did so. She wiggled it for me.
"You don't think we're done, do you?" I asked.
"Are you kidding? We don't have to leave until tomorrow morning. We're so far from being done."
That was a fair point. I pulled the cap off the lotion bottle I'd liberated from the ensuite, and emptied it over her ass. She really did have the most amazing ass; I'd never seen one so tight and firm, and just the right size. She gasped softly as she felt the lotion, and I figured that was partly because she now understood my intent. I wondered if she was going to object, but all she did was angle her hips to offer her ass to me more, then wiggled it again. That was my little slut sister, and she had offered me all her holes.
I dropped the bottle off the side of the bed and took my cock in my hand, running some of the lotion over myself then lining it up on her ass.
"Is this your first time doing anal, Big Bro?" she murmured, holding still for me.
I'd already told her I'd only ever done missionary before today. "Mmm hmm."
"Your first time is going to be in your sister's ass?"
I smiled. "Mmm hmm."
I pushed in slowly, and though the lotion helped I couldn't believe how tight she was. She was making those cute little noises she made, but this time I thought it was more pain than pleasure. I'd have stopped if she asked me to, but she never did, and then I'd pushed past her ring and I was embedded within her. We both gasped with the sensation, and I held for a moment, just getting used to the feeling. She had her head pressed into the mattress, and I sensed she needed some time too. My lips twitched mercilessly; I was perfectly fine with her having a little time, but fuck if I didn't also want to make her hurt.
"I think you have a bit of a masochistic streak, don't you Sis?"
She pushed her hips back up against me. "Only for my brother, the sadist."
I chuckled, and began to move inside her. She gasped immediately. "How does this feel?"
"It hurts, but I feel so full. Don't stop, it'll feel good soon."
I blinked. "You've had anal before?"
"...Yes..." she said, in a small voice. I shook my head. My sister really was a slut.
It irked me that I was playing catch-up with a sister that was eighteen months younger than me. And not just on this, either -- she'd done everything before. My body tensed as I gripped her hips, pulling her up into a doggy-style position, while still being embedded in her ass. She whimpered at the move, somehow sensing my shift in mood, but still she didn't beg me to be gentle. I think she knew she was about to be punished again, and I think the little slut liked the idea.
I sunk my fingers into the soft flesh of her hips, gripping her tight, and then I began to fuck her in earnest. Long, slow strokes as I pulled out of her, then driving forward into her delicious ass, making sure she felt every single one of those thrusts right through to her core. She rewarded me with a cry each time, and the only sounds were her noises, our breathing, and the slap of my hips against her ass. It was a whole new way to spank her, and one I'd have to try again some time. Her ass was so tight around me, so silky and smooth, that it was one of the best experiences I'd ever had. My sister had the best ass I'd ever seen, and now I was fucking it too. Did it get much better than this?
I felt her body begin to tremble beneath me, and for a moment I worried the pain was too much for her, but then I realised the noises I was hearing had become moans of pleasure. Was she coming while I fucked her ass? I shook my head in amazement, and thrust into her harder. Her body clenched around my cock as she gave in to her own orgasm, and it was the hottest thing I'd ever seen. Her beautiful, slender back was covered in perspiration from our fucking, her head hung down with her hair matted and tangled, and her ass was lifted toward me as if in offering. I felt like a god fucking my sister, and I knew I'd have to have her every way I could think of.
Her hair proved again to be a convenient handle, and I loved hearing her gasp as I wound it slowly around my fist, pulling her head back as I began to fuck her faster. The noise of my hips slapping into her ass increased with both the tempo and force of my thrusts, and her moans went to high-pitched cries, in perfect timing with each stroke. My own orgasm had been building for a while, held back solely by my desire to do more things to her, but now all I wanted was to fill her ass with my cum.
I grunted as I thrust into her, and the cries she gave me in response added to the pure primal animalistic nature of our fucking. What was baser than taking a girl like this, fucking her mouth, then her pussy, then her ass? Especially when it was my sister... and with that thought, I was coming inside her. She cried out as she felt my cum splash inside her, and her body shuddered again.
I pushed her forward into the bed until we were both lying down, my chest pressed to her back, and my cock still snugly inside her tight ass. For a moment, we lay like that, both breathing hard from our exertion.
"My sister, the hot little slut," I murmured in her ear.
"My brother, the stud," she replied, with a small giggle. It sent vibrations through her body, down to my cock.
I slipped out of her carefully, enjoying another gasp from her as I did so, then rolled onto my back on the bed, staring up at the ceiling.
"Give me a minute, then a shower," I said, needing some time to recoup my strength.
"Pretty sure I can't walk anyway right now." She moved a little closer, snuggling in.
We lay quiet for a moment, each thinking our own thoughts. It was still only mid afternoon; we had all evening together, all night, and then the morning too. I knew I'd take her again in that time. I still hadn't come in her pussy, and I really wanted to use her mouth again too. She was my little slut to use whenever I wished, and damn if I wasn't going to take full advantage.
"So, did you like spanking me?" she murmured against my chest.
I chuckled. "Yes. And I'm sorry for saying you were fucked up for liking it too. It is hot."
"It is when you do it."
"Ass or pussy?" I asked, my lips twitching in amusement as I deliberately phrased it like she had, only a short while ago.
"Mmm. Either. No... both."
"Heh. Good answer."
"But only if it's you," she said, lazily, snuggling in even closer. Her hand came down to gently caress my cock, still sticky with the remnants of my cum.
"Yeah, well no one else gets to do these things to you. You're mine, now, Sis."
"Mmm," she purred. She raised her hand to her mouth, licking her fingers, before placing it back on my cock. "All yours, Big Bro, whenever you want to use this on me." She gave it a little squeeze to emphasise her point.
"That's a nice thought. I wouldn't want to think about other men using you." I closed my eyes, relaxing contentedly with her draped across my chest.
"There won't be any other men using me. Just you."
I nodded. That was nice to hear. We should probably get up and take a shower, but it could wait a few more minutes. I was too relaxed to move.
"And Daddy, of course," she added.
"Heh, yeah," I said, tiredly. My eyes flicked open. "Wait, what?!"
