The evening had started off innocently enough. An awkward first date set up with my mate's twin sister. She was a nurse and Jim was dating her best friend. When I met them at the student nurse's halls of residence I thought Jim's date was really hot, Jim's sister Chrissy on the other hand, was rather plain looking. Jim's date was an Olympic standard swimmer with short blonde hair, a kick ass swimmers body barely concealed by a short summer dress under which there was obviously no underwear present. Chrissy on the other hand was rather plain looking; short, dark brown hair, some slight acne scarring on her face, but when my gaze wandered down her body things began to look up. She also had a lithe and beautifully formed body. She must have been working out a lot, broad shoulders, pert breasts outlined by her plain brown teeshirt, tight fitting jeans that appeared to be sprayed on her athletic long legs. I had never seen such tight fitting jeans before.
After the normal pleasantries I held the back door of the old Toyota open for Chrissy, and took great pleasure in watching her unbelievable ass wiggle its way into the tight back seat, after which I clambered in behind her.
The night in the disco was uneventful other than the fact that I got to know Chrissy quite well; I really liked her frank and open approach to things. Chrissy seemed to like me too. We even smooched a little to the one and only slow dance of the evening.
Things got interesting when Jim drove the girls back to the student residences. His girlfriend had just finished telling us that it was an all-girl facility and that boys were not allowed in after dark. She giggled then and looked over in the back seat where Chrissy and I were making out, she grabbed Chrissy's arm and said,
"But we know a back exit where we can sneak upstairs, and no-one would know, are you up for some more late night fun Chrissy?"
Chrissy looked at me with an impish grin on her face and said,
"Yes let's do it Annie."
Jim parked the Toyota, and all four of us clambered out. Annie went in the front entrance and checked to see if it was all clear. Chrissy then led Jim and I round back to a fire exit door that had been wedged open. We waited on Annie's text then the three of us scampered up the back fire escape stairs to the third floor. Annie was already there and had opened the hallway door. We squeezed through their apartment's entrance, giggling and making way too much noise to remain discreet. We made it and collapsed in their little shared common room, cracking a couple of beers from their tiny refrigerator. Annie did not even sit next to Jim, but plumped herself right on his lap, with her hand buried in his crotch and her tongue threatening to choke him. After about two minutes of this, Jim struggled up for a breath, raised his eyebrow at me and hurriedly stated,
"OK we're off to bed now; see you in the morning!" With that he carried Annie into the bedroom directly across from the common room.
Suddenly Chrissy and I were a little awkward, it was our first date after all, and although it was adventurous to sneak in here like this, neither of us was too sure of the next move.
"I guess we could go to my room if you like...?" Chrissy said in a questioning way. I already had a boner from even thinking about what was coming next, so I just dumbly nodded.
