"Pft! Easy, and really lame, if I may say so," I said as I removed my shirt. It wasn't as if that was remotely risqué to me, and I probably would've done it at some point anyway, given how hot it was.
She looked at me like she was checking me out for a minute, before I interrupted her by asking her which one she chose, Truth or Dare.
"Dare," she said.
"I dare you to wear my shirt," I said.
She gaped her mouth open and let out a 'Ha!', clearly surprised at my request. Instead of telling her to remove her bra or to do something naughty, I was saying she should wear a shirt.
"Wow, you're not pulling any punches, are you?" she said as she wore the shirt. "Game on, bro. Truth or Dare?"
"Dare."
"I dare you to kiss me," she said. "And I don't mean a brotherly kiss, I mean a passionate, fuck-me-right-now type kiss, full tongue, right here and now."
I knew she was serious, and I also knew how she played the game. If I didn't do it, she'd just come up with something even more serious or embarrassing. But seeing her in only her shorts, knowing she wasn't wearing any panties culminated to a feeling that I felt ashamed to accept at the time, I was attracted to her.
She scooted closer to me again, until we were close enough for the kiss. I was nervous, and it showed, but she was calm, even slightly eager, to some extent.
"The neighbors... what if they see us?" I asked her. "What if they do?" she smiled.
"They'll rat us out!" I whispered vehemently.
"So? It'd be their word against ours, and it's not like they'd be willing to video tape into our private home, it's a crime," she pointed out.
There was some logic to what she said, but before I could think about it any longer, she kissed me. I was in shock, but returned the kiss to complete the dare. I expected her to pull away the second I started reciprocating, but she didn't. Her hand made its way to my shorts, sliding her hand inside them and grabbing my hard dick. I broke our kiss and grabbed her wrist.
"Dani, we can't take it this far," I said to her.
"Yes we can, baby, please let us have this. I want you so bad," she basically moaned.
"But, you're my stepsister..." I managed to get out between her new kisses.
"Yeah, so?" she said as she worked to pull down my shorts.
"This is wrong, Quinn," I exclaimed quietly.
"That just makes it special," she said. Before it could get any further, we heard a car door in the garage, sending us scrambling to cover ourselves again.
"Shit!" said Quinn, as she grabbed her clothes and bolted up the stairs to her room. Similarly, I stood up, and went up to mine as well, since I had an obvious boner, and my mum was about to burst through the door. I closed my door and laid on my bed, thinking about what just happened. I really messed up.
My heart raced with both excitement and guilt. I found myself fantasizing about Quinn, seeing her bare breasts, feeling her hand choke my dick as she'd tried to jerk me off... it was so wrong, but I couldn't help it.
About a half hour passed by before I heard whoever had come home, leave again. It was at this point, when I heard a knock on my door.
"Come in," I said.
She walked in and closed the door behind her. She was still wearing her shorts and bikini top, and had a solemn look on her face.
"Look," she said, "I'm sorry I pushed you into kissing me, and for grabbing your d'ck, earlier, I just thought that I could be open with you about my feelings, and I guess I thought you'd be open to the idea of us hooking up. When I asked you what you thought about incest, I thought that you being open to two adults getting involved, meant that I had a shot."
"Quinn," I interrupted her, "it's okay. To be honest, it was a lot to take in all at once. You weren't exactly subtle and slow, you know."
"So," she said, "what are you saying?"
"I'm saying, let's talk about those feelings you have," I said. I sat up and patted the bed beside me, beckoning her to sit with me, so she did.
"I was afraid that you'd reject me completely," she said.
"No," I said, "I just wasn't expecting my step-sis to come onto me. Plus, to be honest, I hadn't really thought of you in that way before recently."
"Yeah," she sighed.
"How long have you had these feelings?" I asked her.
"About you?" she asked, smiling at me.
"Yeah," I replied.
"Well... It's been a long time. I started having a crush on you," she said, blushing.
"What started it?" I asked.
"You're a hunk!" she laughed. "But seriously, I don't think any one thing started my feelings for you, they just happened, like everyone else who falls in love with someone they meet. I remember one time, you brought home a girl, and you two were fucking in your room while mom and dad weren't home yet. I got so fucking jealous..."
"Wait, a few years ago? When you started acting out and getting in trouble?" I asked.
"Yeah," she said.
"You were jealous that I was with a girl?" I asked.
"Not that you were with a girl, but the fact that the girl wasn't me..." she said. "After that, I started having sex because I wanted to bring home a guy so you'd have to hear me having a good time... never happened." she replied.
