On Thursday night though, everyone was going to a club with the teachers a few miles away. I’m not really the clubbing type and, when I said I was g...ing to stop home, Lisa immediately offered to stay with me. I was curious why she was so eager to but figured she just wasn’t the type either. Everyone went off at 7 and me and Lisa made ourselves a drink and went up to our room. We sat on the beds beside each other and talked for a while, about this and that, then I asked her why she decided not. “It’s ok… really. We were all a little tipsy. It was an accident and let’s leave it at that.”“OK, fair enough, and please don’t say anything to anyone.”“Yeah, no worries there. I’m enough of a social outcast without people thinking I get blown by my sister.”“Don’t say that, you’re a sweet guy and you have a girlfriend! Finally!”“Yeah sure… and Sam? What’s the deal with that? I thought you hated him? The guy is a douche bag. You can do better.”“Hey, spare me your judgment. I was horny and make a. "Ho," she said. "I doubt that. But I felt almost nothing while he, I must say, enjoyed himself at great length and in several positions." Great length may not be the problem."She smiled. "Are you hungry?"I licked my lips and stepped closer, cupping her lush breast and bringing my mouth it its pink nipple as I popped it from its lacy nest. Two licks and nibble, and it swelled and hardened very nicely."Please," she said, holding my head to her chest. "I need some time to rest, to recover. He was. Ohhhhhhhhhh”. she went still for a second, and said “please rub the head of your penis on my pussy……I want to feel that……” I loved to hear her talk dirty and gladly did what she wanted me to. “I want you inside me.” She said breathlessly.I lifted her legs high and wide and pushed my penis in a few inches. She was tight and felt so warm and soft. “OOOOOOOHHHHHHHHHHH, SLLLLOOOOOOOOOOOOOWWWWWWWWWLY BABY, YOU WILL HURT MEEEEEEEEEEEEEEEE.” Some thing came over me and I shoved in the whole 7 inched.
