But ... why wouldn't you be a little suspicious of my motives?" I asked, this time with a smile."Because I have a very big boyfriend who is very prote...tive of me," she giggled.She had easily defused the tension."Okay ... I've been warned," I grinned. "Anyway, we've missed this week, so why don't we plan on meeting at one-thirty next Thursday in the library and between now and then, you can think of where you want some help and we'll go from there."She gave me a thousand watt smile and nodded. Suddenly I felt one more hand sliding between me and the mom’s thighs. That was a rough big hand. My mom was all for it! She tried to move me aside a bit. I lowered my eyes and saw that man’s hand fondling her thigh through her dress lowering down and down. Then the hem was slowly pulled up by it. I saw that rough hand squeezing the tender tanned skin of my mom. I saw his fingers moving apart the thing strings and trifling her hairy place.It lasted about 15 minutes until the subway become less. So, this was a typical small party. About 25 people gathered around the fire pit which was in my back yard. The house was always open so people could use the fridge or washroom etc. It was about midnight or so when I accidentally spilled a drink onto my pant leg and decided to go change since I was at home. I went to the bedroom and grabbed a pair of pants, dropped the ones I was wearing to my ankles and suddenly there was a loud crash as the door popped open and in came my girlfriend. Scared. . ?" Yes, and what?" Well, sometimes after I've been with Cricket, I get this certain thrill about thinking about Shawn doing me." What do you mean?"Sheryl looked closely at Dr. Jameson's face. "Well, one time Shawn fucked me not long after Cricket did, and just the thought of him sliding into me through Cricket's cum set me off. I don't know why, but the idea of Shawn getting sloppy seconds really turned me on. You know what I mean?"She was surprised that the expression on William's face.
