It was time for the birthday cake and open the gifts. After everyone was served a piece of cake, they all chimed in and sang Happy Birthday. I blew ou... the candles after which came the presents. As I opened each present, I thanked that person and after the last present was opened, everyone returned to mingling and having a good time.After a while, I went around once again, thanked everyone for coming and for their gifts. I told mom that the three of us were going to my room for the night.. “It was a gift from an old boyfriend and I wore it once for him and never went out in it. It is sluttier than the dress, isn't it.”“Yeah, I guess,” said Jana, still not understanding where her roommate was going with it.Vicky sighed.“It can't be helped then, I guess,” she said.Then she twirled about and went back into her room, her blond ponytail swinging behind her. A few minutes later, Vicky emerged wearing the outfit. It was quite obvious that she wasn't wearing anything under the white tube. Come on everyone. It's time to get ready to read ourselves to sleep."Jill gave me a kiss and said, "Same time in the morning right or do you want to get an earlier start?"I suggested, "Instead of meeting at six-fifteen, how about six? That way we can all get our weight training in."Everyone nodded and we parted to head upstairs. Shelly followed Mike and I into our room. She said, "Okay you two, I want some guy/guy show stuff then you two are gonna double fuck me. I'll bet you even have some. I slipped a finger into her and immediately she said "More!" so I slipped another finger, then another, soon I was using all four of my fingers in her cunt, she was growling with pleasure, scratching my shoulders and neck as I brought her to orgasm. When she finally came, she told me to bend over.As I bent over I thought "This is it, the first time someone does something to my ass!" She takes my butt plug, lubes it up, and works it into me ever so slowly. "That feel good baby?" she asks, I.
