I couldn't deal with that. I couldn't really see him lasting very long in a college environment, where discipline was an essential, at least to my way...of thinking.The universe's normal sense of humour came to the fore, as the only available room would happen to be on a co-ed floor in a co-ed dormitory. My first foray to the men's room proved to be a veritable obstacle course. I was going to have to invest in a robe, traipsing to the men's in either just shorts or wrapped in a towel would be. Biff was now sliding in and out of Erin's ass with ease and it was quite a sight to see his large cock impaled in her tight hole. Biff watched his cock move in and out of Erin's ass as he stroked her beautiful buns. Rita was beside herself and she jumped on the bed to join the threesome. Rita slid under Erin's pussy and watched Biff's cock slide in and out of her girlfriend's ass. Then she went to work on Erin's cunt and soon had her thrashing around and cumming on her face. Biff tried to. Margie smiled widely at me and smacked my mom’s ass, “good girl” I heard her say as she pushed her strap-on deep into mom, eliciting another deep moan. I was frozen in place watching, totally transfixed. Margie leaned forward and slid both hands under my mom to cup her breasts. She kept her eyes locked on me as she leaned back, lifting my mother upright so I had a clear view of Margie’s hands. They cupped under my mother’s breasts. It felt like my legs had gone numb and my heart had stopped. Most had seen me naked at rugby events so I was able to laugh it off and actually got a bit of a kick out of it.The girls both looked at me and laughed out loud. I ran over to the counter and tried to grab them off Mary but she pulled away and held them out of reach. Just then I heard the beep, beep as the door opened behind me and somebody came in. Mary and her friend immediately made themselves look busy, the friend wondering off as if in the midst of a task.“That’s my brother and he’ll go.
