Up until about five years ago, RPI had been men only, sort of like The He-Man Woman Hater’s Club for nerds. Historically, the only time women had ev...r attended the school had been for things like World War II, when no men were around, and they needed women engineers. As soon as the war was over, the women were sent packing. As it was, in 1973, after five years of co-ed education, it was still 14 to 1 guys to girls. You didn’t go to this place to get laid! There were so few women in the freshman. My cock began to harden and I was beginning to get excited. I had at last found out what she looked like naked; it was something I had wondered about for a while. As I stood behind her, I slowly eased my hard rod up against her ass cheeks to check her response. To my surprise, she reached out and grabbed a handful of my cock from between her legs and began to rub it against her moist mound and ass. Without hesitation I began to ease the head of my rod into her with caution. "Mmmmmmm," she. It took a while for Alex to get over that. He would tell us of how much he missed her and said that he would never get into a relationship with another woman.Alex comes around every six months and about a year after his wife’s death, he started flirting more with my wife, which I told him I was okay with. I could tell that my wife felt a lot of empathy for Alex and would flirt right back. Long story short; after several visits of me pushing her, I succeeded.With Alex in the picture, she is. The taps ran, and while the bath was filling he showed me her wardrobe. I selected black lace undies; hold up nylons, a pencil skirt, and a silky blouse with high heels and a black fur coat.We lay them out on her bed. He added the bath oils she had requested and we returned to the living room confident we were ready. Promptly at three we heard the key in the lock. We were off! She arrived kissed him, then me, introducing herself as Dawn and eyeing me up and down as we had never met before..
