I looked up to see John was tossing a football up into the air and catching it as he walked with his bag thrown over his shoulders. My pussy started t...o tingle as he got closer.Dad told me here he comes. I told him you go talk to him I will wait here. Dad walked over to him just as he tossed the game ball into his car. It was a little dark in the parking lot and John would not be able to see who I was at least yet plus dad‘s truck also hid me.I heard my dad say, “Good game today son,” as he. I got beneath the covers just as Karen staggered through the door and into bed, obviously too drunk and exhausted to even think about showering. For a few minutes she lay still beside me, and I assumed she had fallen asleep. A heavy smell of sex filled the air as I tried to process what the hell had just happened. I was contemplating slipping into the bathroom to relieve myself (again?) and clean up when I felt a hand slide across my stomach, down to my sticky crotch, and grasp my gooey, erect. The fourth floor was private and I've only been up there once, during my initial orientation.Though seldom used by anyone, it was the only floor with its own private cleaning crew and requiring a key for access. It contained only thirty or so volumes, really old and fragile things that took special storage and handling to preserve them. All access was by appointment only and then, only in the company of the head librarian.It had been very slow for the previous couple of weeks and really dead. I couldnt wait any longer and slowly pushed forward through her open pussy lips, inch by inch my cock began to sink into her dripping cunt. When I was halfway in, it finally hit me. I was actually about to fuck my own mother!. As sick as society thinks it is, every guy has this fantasy, but how many of them actually get the chance? Not many and I certainly wasn't going to blow mine.I pushed in as far as i could go, then pulled back out of her with a pop, i wanted to tease the little bitch, draw.
