Sharon and I rubbed our nearly naked bodies together as we kissed. My hard cock naturally found its way to the hot wet slot between her legs. I rubbed... it along her slot, hoping against hope to get lucky that night.I rubbed my erection up and down, trying to nudge her clit as we humped together. I could feel Sharon's lubrication preparing her pussy for fucking. She was panting and moaning from the feelings.I dipped my cock down a little lower and went for it. I nudged the mushroom shaped head of. I thought to myself "what am I doing". This is not right. But I was overwhelmed for curiosity.I was shocked to see my mom wore thongs. I mean THONGS. This was in that time where thongs were only for young girls and were remarked as kinky items to use. Some were really sexy and I immediately started to have a huge boner. A boner for MY OWN MOM. "Shame on you" I said to myself. But I couldn't helped. I was obsessed with her, and because I didn't have any girlfriend for a long time, I lost myself. Remembering what she said about avoiding the frat houses, I didn't bother asking if she'd ever considered joining a sorority.There were some sizable missing pieces in the puzzle I was putting together about her. The biggest seemed to be a lack of lasting friendships. Other than Vivian, the people she interacted with were almost exclusively from her current environment. Friendships begun in past classes dropped away after the class was over. Friends from before college were not friends with her. Back at the flat, I fixed her another drink, another very generous measure, I didnt want her sobering up too soon. I took her into the lounge to introduce her to the other guys. "This is Bridgette, my gorgeous new girlfriend." Hi there." said the guys. She seemed impressed with our leather sofas, state of the art home cinema system and masculine but stylish decor. We weren't slobs and my mates were as fit and good looking as me. Simon had dark hair and a mediterranean comlexion, he was a bit.
