Faculty and staff were off taking care of things they had let slide during the hectic final days of the semester. As a result, a handful of faculty an... the full time graduate students who were working on their research were all that remained on campus. It was a highly productive time for everyone who remained at work.Betsy had finished examining the genetic data gathered and was sitting at the small desk in the Dr. Wood’s laboratory. She was thinking back over the activities of the past few. I couldn't believe how naughty I was feeling, doing all of this, and in H's room of all the places. I sank to my knees in between Daruis' thick thighs and marveled at that thick, black cock stood to attention before me. My knee knocked against something on the floor and in the dim light, I reached for the small brown bottle, unscrewed the lid and took a hit, as if my inhibitions couldn't lower any further.At that moment, I began thinking, a lot has changed these past few weeks. Just casting. No one would know it had beendeliberate, not even the stranger behind me. We were crushedin an elevator like sardines in a can. Then there was deliberatetouching.I was wearing a knee length skirt that was lightweight crinkledcotton and it flared out loosely. I felt this stranger'sleft hand slid up the back of my left leg ever so lightly movingmy skirt up too. I froze. It was so subtle. Of course I couldn'tpretend I didn't notice this. Still I just stood there.I felt his finger begin to walk the. If I did get pregnant, none of them would ever be told and I would let Don think he had gotten the job done. We spent several minutes like this. Stroking two hard cocks while sucking another and having a fourth guy playing with my titties and rubbing my clit. Every minute or so they would trade positions so everyone got his share of the fun. Finally the guy who was behind me at the time took hold of my hips and told me to get my ass up in the air and spread my legs. Now I was still on my knees.
