The car was silent for a while. Beth and Paul had nowhere to speed off to. They drove slowly through they home town, and Paul felt a strange mixture of nostalgia and confusion.
"Paul…" said Beth. "Did you…I mean, did you and mom…?"
He knew what she was trying to ask. Strangely, the question turned him on a little. He sickened by how hot and arousing the moments right before Beth had showed up had been, and tried to shake it out of his mind.
"No…" said Paul. "But some of the Milonics women…well, let's just say that you showed up at just the right time."
An odd voice in the back of his head asked whether Beth really had shown up at the right time, or if it had been precisely the wrong time. His body was still tingling, as if it had a better sense than his own mind about what would have happened if things had gone a little further.
"I'm glad I did too, baby bro." Beth smiled at her brother and ruffled his hair. "Mom has told me some stuff over the phone about those crazy people. If they had it their way everyone would just be screwing their friends and family in the streets."
Paul smiled a little, and watched as Beth pulled into a motel parking lot. She brought the car to a stop in a free spot, and the two of them climbed out of it. The sun was setting in the distance, and it gave the moment a slightly ominous feel.
"Can you split the cost of the room with me?" asked Beth. "College life has been draining my bank account."
"Sure," said Paul.
The two of them walked over to the check in building and headed inside. Behind the front desk was a bookish looking man wearing a pair of thick glasses. He smiled at them from behind a magazine as they came in and wheeled his chair over to a computer.
"Hello," he said. "Are you two going to need a room for the night, or just a couple of hours?"
"Uh…what?" Paul glanced over at his sister, who had the same puzzled expression on her face. The man smiled and let out a small chuckle.
"I'm asking if you think you'll be doing it just once or twice, or if the beds going to be rocking for the whole night." The man winked at Paul, a dirty smile forming across his face. "I'm assuming for the night? Teenage hormones are a powerful thing."
"We…He's my brother!" Beth was blushing bright red, and slammed her hand down on an empty spot on the man's desk.
"Oh…" said the man. "Oh! I'm so sorry! Here, how about I give the two of you a small discount. That was a really terrible assumption on my part."
Paul shook his head and sighed. It felt like he couldn't escape from it, whether it was his mom, or his sister. He looked over at Beth and saw the anger in her face, along with something he didn't expect. She looked hot, as though the man's misunderstanding had gotten under her skin in places where it shouldn't have.
"Alright, room 211 is open," said the man. "Checkout time is 11 AM. And again, sorry for the mistake."
He handed Paul the key, and then lifted his magazine back up, as if trying to cut himself off from the emotional chaos that he had brought into the situation. Paul looked at his sister, and then turned and headed out the door.
"Well, that was dumb," said Beth, as they made their way up the stairs towards their room. "How you could you mistake the two of us for…I mean, it's just ridiculous."
"I don't think he thought twice about it," said Paul. "Most of the people who come through this place are probably here for that reason."
He looked over at his sister, and couldn't help but notice just how attractive she was. It had been confusing for him growing up with both her and her mom in the house, especially as a horny teenager.
"Well, here we are." Beth stopped in front of one of the doors, and Paul walked over and unlocked it. The room on the other side was tiny, with only a single bed, a television, and a tiny bathroom.
"Yeah, here we are." Paul kicked off his shoes and walked over to the bed, taking a seat on it. Beth closed the door and turned on the light.
There was a strange tension in the air. Paul wondered why it felt so weird with just the two of them there. Beth smiled at him and slowly started walking over. She'd taken off her jacket, and Paul's eyes were instinctively drawn towards her chest, with her nicely sized breasts pushing out against the fabric of her shirt.
"Paul…can I ask you something?" Beth's tone was serious, but also excited. Paul looked at her and felt something electrified in the air as they made eye contact.
"Of course, sis, anything."
"Do you think…I know this is going to be hard for you to answer, but If hadn't shown up, do you think you would have…gone through with it? With mom?"
Paul felt his heartrate begin to pick up. His cock also began to stiffen in his pants. This was not the type of reaction he wanted out of his body, not for a question like that.
He shook his head and then sighed, feeling like it was very difficult to be anything but honest with his sister.
"I don't know, Beth," he said. His sister didn't react, and he began to feel as though he needed to explain more. "I mean, it felt almost like I was being pressured into it, you know? The whole Milonics thing, and Bea, and all of the women there…they acted like it was totally normal. They even said it would help me and mom…well, become closer."
Beth put her hand on his shoulder.
"It's okay, it's not your fault," she said. "We'll head back tomorrow, talk mom out of this nonsense, and then we can all move past it. This doesn't have to be a big deal."
"No, of course not," said Paul.
Neither of them said anything for a moment. The room felt hot, and stuffy. Paul looked as Beth and the two of them locked eyes, both waiting, but not knowing what for.
"Paul…" Beth whispered his name slowly, and her hand began to run up his. Paul slid closer to his sister, and looked deeper into her eyes. She was so beautiful, and it was just the two of them in the room. It was as though their bodies had come to a decision free of rational thought, free of objections.
He leaned in and kissed Beth softly on the lips. His sister let out a soft breath, and ran one of her hands up his side. Her touch felt so warm and electrified, and Paul's cock was stiffening in response to it, rising for the occasion.
"What…what are we doing?" asked Beth. Paul kissed her on the neck, and she let out a moan. Her question was one that he felt like he was also silently asking. Just what the hell were they doing?
His sister's hand slid across his leg and came to a rest on his hard package. The two of them collapsed back on to the bed and stared at each other for a moment, Beth continuing to play with his cock through his pants as she began to shake her head from side to side.
"We shouldn't…" she said. "Paul, this is insane! It must just be a side effect from what you went to."
"Yeah, it's no big deal," said Paul. "And you're right, we're just being dumb right now."
He nodded, and then their bodies pulled together again, as though drawn by some type of sexual magnetism. He kissed his sister passionately, feeling her tongue come out to meet his in response. His hands ran across her back and down her jeans, feeling the soft fabric of her panties.
Paul was grinding his hard cock against his sister's body, and it felt amazing. He felt guilty, and ashamed, but a sick sexual thrill flooded over him and drowned out the other emotions. It was pure bliss, sensory overload, and his body moved automatically to take it even further.
He quickly began unbuttoning his sister's blouse, staring into her eyes as he did. The look that the two of them shared was enough to say a thousand words. All of their worries and doubts, fears and concerns, and intense desires were there in between them, reflected in the eyes.
"Oh god, Paul," whispered Beth. He nodded, as though affirming to her that yes, it was really happening.
The last button was undone, and Paul pulled his sister's blouse back and over her shoulders. Her breasts looked amazing underneath it, and he pushed forward and grabbed them with his hands. Beth let out a small moan and rubbed her hips against him. It was all the encouragement Paul needed to take things to the next level.
He unbuttoned his sister's tight jeans and slowly pulled them down, admiring her perfect curves and inviting thighs as he did. Paul felt awkward as he rushed to strip his own clothes off, disrobing in front of the older sister that had both teased and encouraged him throughout his childhood.
"Beth…" Paul looked at her on the bed, and he looked at his own big, rock hard member, pushing out against the fabric of his boxers.
"Just…this one time, Paul," whispered his sister. Paul climbed on top of her and pulled his cock out of his boxers, and then began rubbing it against his sister's pantie covered mound. His hands went to work on her bra, exposing her gorgeous, perky breasts, and then finally, he pulled down the thin strip of fabric separating him and his sister from illicit, taboo bliss.
"Sis…" Paul felt like he should say something, but couldn't find the words. His thoughts were clouded by his urges and lust, and more than anything, he just needed to get off. He pushed the head of his cock against the entrance of Beth's cunt, as if knocking on the front door, and asking to be let in.
Beth was already wet and ready for him. She ran one of her hands through Paul's hair, and with the other one, slowly pulled his manhood inside of her. Instantly, Paul felt as though he had been dropped into a warm, pleasurable bath. His sister's pussy was tight on all sides and felt like it was drawing his cock further and further in.
"Oh god, Beth…" Paul moaned as he began to thrust. He had never had sex before, not with anyone. It was confusing for his first time to be with his sister, but also comforting. He felt as though she was looking out for him, just like she'd done back when they were kids.
"Paul, oh god, Paul!" Beth moaned and pulled him in, wrapping her arms against him as the flesh of their bodies met.
Paul had never realized that anything could feel so good. He felt as though it all made sense. The tension that he'd felt around Beth, and the strange thoughts he'd had about her, it had always been hinting at this. Paul had entered a vast realm of pleasure that had been there all along, right under the surface.
Beth was breathing heavily and biting one of her lips. She wrapped her legs around Paul and rubbed his cheek with one of her hands, as though accepting him as both a brother and a lover. Paul was amazed by how good her pussy felt, amazed by how close and connected he felt to his sister.
This was what the Milonics movement had been talking about, he realized. As Paul pumped his cock deep into his sister, the sound of their bodies slapping together hot on the air, he knew for a fact that the two of them had moved into territory beyond where most siblings ever could or would reach.
"Fuck me, Paul," moaned Beth. "Oh god, don't stop!"
Paul couldn't have stopped himself if he'd wanted to. It felt too good pushing into her, and something very primal and animalistic had taken over. He was showing his sister a side of him that he didn't even know had existed a couple of hours ago.
Beth began to tense up, and she let out a cry and buried her face into Paul's shoulder. He felt her cunt tensing up around his cock, a sensation that was just enough to push him into similar straits. He slammed into her a couple more times, really getting all of him inside of her, as deep his cock would go, and then felt his body release.
Paul shot his cum deep inside his sister without hesitation. Each spurt felt as though it was leaving a permanent mark in both of their memories. There was no going back. Neither of them could ever forget.
He collapsed onto the side of the bed as his orgasm slowly died down, and Beth cuddled against him. Paul felt as though he should say something, but he didn't know what. It was hard for him to process what had just happened.
"Paul…" whispered Beth, after a moment. "We shouldn't have done that."
Paul looked over at his sister, and shook his head.
"No sis, I'm glad that we did that," he said. "I…I think I understand now."
He got up off the bed, and started putting his clothes on. Beth sat up, pulling the sheets around her as she did.
"What are you doing?" she asked.
"I'm heading home to talk to mom," he said. "Alone. I'll walk back, don't worry about your car. I'm going to talk to her, and we're going to face this thing head on."
"Paul…" said Beth. "Are you sure about this?"
Paul smiled at her.
"I've never been so sure about anything in my entire life."
