In addition to its real name, it was referred to as the faculty dorm by some students. Most of the residents were indeed faculty or staff in their late 20's or early 30's, except for us two who were in our late 30's.
Rachel and I both had spouses, no kids. Even so, we had both noted a mutual attraction early in the three-week session and we needed to be very discreet. And we were. I'm sure that sex went on in the dorm regularly, but maybe during the day. But we both had rehearsals all day and night, so late night became our time.
I would come to her room (they were all singles) late at night. We had agreed that kissing and touching would be ok, but that's all (the goal was to satisfy our needs while not going too far. Being away from spouses for several weeks was tough). We got into the habit of these little nocturnal visits that seemed to satisfy us both. At least for a while.
I would kiss her and we would move to the bed. My hand would stimulate her crotch through her jeans, as she would cum with some simple rubbing. I would then sneak back to my room and cum myself. We both seemed ok with this arrangement, and I certainly enjoyed the fun of discreetly seeing someone else and giving her pleasure. I got used to the self-stimulation.
However, there was one night that was different. It was on the last night of the session (of course).
Her hand moved mine to unbutton her jeans and finger inside her, which I gladly did. Soon she whispered, "Use two fingers." I inserted both (I wished I could insert something else!) and moved them in and out. She resisted my attempts to give her oral pleasure, preferring the manual stimulation only. Her deep moans of pleasure and heavy breathing gave me great satisfaction, however.
