The Unexpected Truth Or Dare

[neerathemall]

Before pushing back against her flesh, I scooted lower a bit and bit my lips as I felt my cock pressed deep between her buttocks. Her lower back and top of her ass had been great before, but this was amazing. And hot. Physically hot I mean. The deep space between her thighs and buttocks was already hot.

With my face buried in her hair and pressed between her shoulder blades now, I delicately grabbed her breast again. I felt one last warning, one last alarm that this was my last chance to stop this. Fuck it. The only person that cold stop me now was Olivia. I was too far gone. For long intoxicating moments I pushed the underside of my cock as deep as it would go between the cheeks of my sister's round ass. Shit that was good! But I wanted more. We always want more.

Letting go of her breast again, I pulled back slightly and guided my cock down. When the head of my cock touched her burning hot thighs and pushed in slowly, I trembled. Very slowly because I didn't want to wake her and my precum wasn't yet enough to lubricated her skin, I pushed in.

For long and very delicious minutes I pushed deeper and deeper, my cock trapped between her smooth thighs and lodged against her panty covered pussy. At one point, my precum managed to make the movements dramatically more exquisite, and at last I went as deep as I could. I could now feel her ass pressed against the top of my thighs as I was fully sheathed. Sheathed between her thighs, yes, but that was more than enough for now.

My sister's skin was incredibly soft, her thighs really smooth. With more lube, they would be a perfect fuck toy in themselves. With my hand on her hip now, I guided her body and timed my own slow thrusts carefully. A bit faster and I would cum in minutes, but as it was I knew I could enjoy this for hours...

Of course, that relatively safe plan was not destined to work. As amazing as fucking my sister's thighs was, my entire being wanted more. All I needed was to be one inch higher. The upper side of my cock was pressed against her panties, and I could feel their soft cotton underside. And the shape of her lips. And the heat. Damn it Olivia's pussy was so hot! And yet I hadn't felt anything from her! Was she having an erotic dream? Or was she unconsciously responding to her brother's lewd actions? Or, was she simply feigning being asleep? When that possibility occurred to me, I froze. Was it possible? She had kissed me, had let me suck her breasts... Was Olivia willing? Was it possible that I had woken her and that she...

I had no idea, and tried to focus my attention on her, watching anything that would betray her. Nothing. Absolutely nothing. There was only one way to find out. I felt my hard cock twitch at the thought, and knew this was going to happen. I slid my hand from her hip to her ass and grabbed the side of her panties. Gently, slowly, I pulled them down. And down. And down until I felt my cock pressed against Olivia's naked pussy. Hot. And fucking wet. Either Olivia was having an erotic dream or she was awake. In any case, I was going to know very soon. Holding her panties down, I pulled back until I felt the head of my cock against her wet lips. A second later, I was inside my sister's pussy.

Burning hot and more than wet enough, I pushed in and didn't stop until I couldn't go any deeper. My mind was a raging fire, overwhelmed at the thought and realization that I was fucking my sister. Before I could even get all the way in, Olivia woke up, mumbling a "Ethan? Ethan is that you? Of shit... Ethan!" She turned her head towards me, grabbed my own with her hand and, delightfully, arched her ass against me. "Ethan is that you?" she asked again, moaning my name.

"Yes..." was my simple reply.

Olivia, my sweet sister, impaled on my cock, moaned out loud "Fuck! Fuck me... Take me!"
