I opened my door and stepped out on to the landing, just as Lin stepped out of her room at the other end. The lights were off, but there was definitel... enough light creeping in from the street that she would have had no doubts of my nudity. She herself was in nothing but her bathrobe.I didn’t act any differently to how I normally would. I whispered “hey” as I walked past her and down the stairs. It was too dark to properly see her facial expression or her eyeline, but frankly I didn’t care.. I stood up as an arm reached around and embraced my waist, without a word I felt the guy behind me fumbling with his belt and than he pushed his rigid dick up into my anus. Standing there in the hall of a blacked out adult book store, I was entertaining my second dick of the night without seeing who it was or being introduced. My second lover worked his penis quickly in and out of my anus till he too shot his load of man juice up my butt. When he had pulled from my anus I quickly laid against. I was a lot of things, but dumb was not one of them. My mom reamed out a few of them severely when they automatically assumed my grades were a result of cheating. Most of them quickly learned to keep their thoughts to themselves. My mom could get really vicious when it came to me being unjustly accused. Now if I really did cheat, that would've been an entirely different story! There's no way in hell I would even think of pissing my folks off like that. Disappointing them was unthinkable.. "Your doctor must like you," she said, "If she had written 'CF', that's not as enjoyable."I asked what the procedure was and Sandy told me that she would use the wand and a probe device to attempt to induce an erection and an orgasm while recording the functioning of my prostate and erectile systems as an ultrasonic video. I told her that I had never heard of anything like this and she said that the medical profession hadn't found any better way to get these images and that they wanted to keep.
