We are off for a family weekend out of town. Some how my step-sister and I get stuck sharing a room, and not just a room, but a single bed. It's awkward enough as it is, since we are both grown adults now. Better yet, we both like to rest barely clothed! The first night, we go to rest, and I end up pressed against her ass. I get hard, obviously, and decide to try and jerk off. I end up getting really distracted by her ass and end up having to have a feel. It doesn't take me long after that to just stick my dick in her and start pumping away. I eventually can't take how tight her pussy is and end up cumming inside of her. The next night, is even more awkward. We agree that we should forget anything ever happened and just get through the night. Well, no she was horny, so this time it's her turn to fondle me. Eventually I come to, and give in to letting her fuck me. As she is about to cum, I try to push her off before I cum inside her pussy AGAIN. She wasn't willing to ruin her own orgasm, so, I end up giving her a creampie for the second night in a row. We definitely can't ever share a bed again!
