Ive always thought of what i wished had happened and today i decided to write it down. Read my other story first before reading this one :)....So ther... we were, two drunk teenager but naked jerking off beside each other watching some porn. As we continued to jerk i couldn't help but watch him stroke his cock. All i wanted to do was touch it. Eventually he looked over and noticed i was staring at his dick. He then asked me if i had ever done this before with other guys. I told him i had but we. " That's too funny." Yeah, well, my Mom teaches history at Penn, and she focuses on American History, so there was going to be a president in my name somehow. It was just a matter of bad timing." Wow, a history prof.

Electrical engineer," he said."So nerdiness is genetic?" He gave me a look.I smiled. "I mean that in the nicest way." So. We talked about what to do today and she wanted to go and look at some old stately house, we got ourselves sorted and in to the car. She was dressed more like the old age pensioners that visit these places, white blouse and long skirt with hand bag.Starting the car, I knew different, pulling her skirt up revealing black stocking and no knickers. Within twenty yards of the caravan, my zip was down and she was using my cock like a gear stick, how we got to that stately house, I don’t know.We had. ."Was it just her imagination, Ruth wondered, or did her big sister sound just a little disappointed? Kristen came over to the side of the bed at last and started to sit down, but hesitated at the last moment, her attention returning to the door yet again. "If we're going to be sharing a bed tonight, I think I'd better shut the door. We don't want to have mom and dad spot us like that in the morning!"Ruth just smiled as the other girl trotted over to the door and pushed it closed quietly,.
