I was eighteen and my girlfriend was attending an all-girls college about thirty minutes from where we both grew up. Anne was a cute brunette with a dancer's body, which meant she had spectacular legs and an ass that begged to be fondled. It also meant that she was an A-cup, but that never bothered me for a second.
I would go up to visit her every weekend and was allowed to spend the night on Fridays and Saturdays. The dorms were set up for two to a room and her roommate was a ditzy blonde with a Barbie Doll figure, named Evelyn. Evelyn's boyfriend, Steve, was a big guy and a little bit of a redneck, but overall a good guy. We all became fast friends and started doing most everything together.
We had several borderline exhibitionist sexual encounters since almost no one ever closed their room doors, but that’s a different story. The most interesting time was the night that Steve and Evelyn suggested that we switch partners after the lights were out. Now, I assumed it was nothing more than a joke and initially took it that way. I was a bit surprised by the whole thing, but even more so when my girlfriend, Anne, jumped up and out of our bed.
As I was thinking of something witty to say, Evelyn slid right in and backed up until her soft, smooth ass was rubbing against my semi-hard cock. To really get the picture in your mind you have to know that both of the girls only wore t-shirts and panties to bed and they weren’t granny panties. So when Evelyn backed her luscious ass up to me I felt mostly skin and her thin cotton panties. When she started to wiggle it about, my semi-hard went to fully-hard in moments. At this point I was sure that she would jump out and go back to her own bed, but that didn’t happen.
It was pitch black in the room, and I was struggling to see the other bed because I was sure that Steve was going to flick on the light at any minute. As I was waiting for Evelyn to leave, she reached back and pulled my free arm around her, pressing it into her large soft breasts. Stunned by her actions, I hadn't really responded other than with my 'thinking on its own', smaller head which was throbbing and fully pressed into the crack of her ass.
What made all of this even odder was that the whole time that all of this was going on, both of girls were yapping away like we were sitting around watching television.
Apparently Evelyn wasn’t happy with my lack of participation and started squeezing my hand with hers which was wrapped around her left breast. This last move started to clear the fog a little, and I figured that if I went along for a minute that this whole charade would end. Finding her very hard nipple, I gave it a little pinch and began rolling it between my fingers, my assumption being, that she would jump out of bed and make some fake display of anger while going back to Steve.
To my great surprise, that‘s not what happened. In fact, she pushed harder against my cock and pulled my hand up under her t-shirt to her bare breasts and got me fondling them again. Once she was satisfied that I would continue, she raised her left leg just enough to allow her hand through to fondle my underwear covered balls. I’d like to say that I was worried what my girlfriend was doing with Steve, but at eighteen I was only thinking about what was in front of me.
While it seemed like twenty minutes had passed, all of this had occurred in about one to two minutes and by now I was on board with whatever Evelyn suggested. Since I was now ‘all in’ figuratively, I decided to give Evelyn what she wanted and pulled my right hand out from under the pillow to start working on her other breast. That seemed to kick her into overdrive and she quickly slid my cock out of my underwear and gave it several long slow strokes. Releasing me momentarily, she quickly slid her panties down to her knees then reached back for my cock.
