I pushed his thick head into my mouth and began to suck him with a feverish passion as I turned my head swirling his cock around in my mouth while I s...ueezed and rolled his thick balls in one hand and twisted his shaft with the other. I could feel my pussy dripping with every salty sensation and taste of his delicious pre cum as he leaked into my mouth. I used all of my tricks and everything I could think to make up for what seemed like ten minutes when I could feel his cock getting extremely. Had Sheryl left it there? Was she so sure Rachel would cave? They had become pretty good friends this year. They were even talking about getting a house together off campus for next year. The beeps of the number on the receiver rang in Rachel’s head as she dialed the professor’s number. The phone on the other end rang several times. It seemed like forever. Why wasn’t his voice mail on? Rachel was about to hang up when the other line got answered. ‘Hello?’ ‘Hello, Dr. Gordon. This is Rachel.’. I walked into their bed room. When I got there, he scooted over and opened the covers and told me to get in. So I did. He cuddled me for a while, but I felt his cock start to get hard, real hard. The head of his cock poked gently at my pussy. He fell asleep though and I couldn't resist stroking his cock. I was just in a long sleep shirt, no panties no bra. I took his cock by it's shaft and put it between my legs. I was wet and I wanted to just feel it against my pussy so bad! So I. And so it went on; I would stare at my Mommy's legs and arse for hours until I couldn't take it any more and my throbbing cock begged for release and then I would lock myself in my bedroom and masturbate into the same pair of my sister's nylons that I had acquired two years ago. By now they were laddered and holed and had become crusty with dried semen, but I never thought of washing them; they were my talisman. Likewise the panties that I had acquired at the same time were now semen-encrusted.
