This is probably tamer than most stories here but, unlike most of them, it happens to be true.
My parents were visiting for the weekend and we ended up going to bed a bit later than normal for a Sunday night. Nothing crazy, but a bit late. My parents were asleep in the next room. After a bit of tossing and turning, I finally fell asleep.
About an hour later, I was suddenly woken up by my wife rolling over and lying on top of me. Now, I don’t know what exactly it is, but when I am woken up in the night, I have this tendency to horny. Really horny. Like, disgustingly horny. This was definitely one of those times. Feeling her petite body on me, hearing her breathing, these things didn’t exactly help. Soon my breathing was getting loud and my cock was stiffening. She could feel it. Within seconds, she began kissing me, biting my lip. The little nympho wanted to fuck.
I pulled her on top of me and we made out furiously, hungrily. My hands were all over her body, rubbing along her back, cupping her ass. I pulled my underwear off and, almost angrily, peeled hers off as well. I felt like a wild animal, so inexplicably aroused.
