She saw this and slowly started rubbing her left hand over my crotch.I didn’t want to stop her so I bent down to pick up my bag and keep it on my la...s. As I bent down, Shreya also bent down pressing her boobs on my arm and whispered in my ear, “Tonight is going to be one great night!” and licked my earlobe.I instantly understood that I will finally get to have sex with Shreya, something that I had wanted to do for a long time!For the remaining duration of the lecture, we felt each other nicely.. I got her naked and was looking down at her great little body when I was aware of a noise at the back of the house. I then remembered that the window cleaner was due on his monthly visit. We had often fantasized about being watched having sex and whenever we did it was great sex! I never really thought about it actually happening and in any case my girl would not have agreed to arrange for it to happen. I knew her well enough. I thought, however, if I could get her in the mood maybe she would. " It was at that moment of realization that she noticed she was wearing a beautiful white dress. Startled, she lowered her eyelids just enough to cut the glare of the lights. She almost let out a gasp as she saw past the lights out into the crowded auditorium of the opera house.

" Of course this activity was having a similar effect on me, making me hunch over because my dick was so uncomfortable."You gonna finish this big boy? Huh? Or just tease, Huh. Waddya gonna do?" Shirley teased.With that, I unbuttoned her jeans and grabbed her panties and jeans at the same time then pulled them down to her thighs. I dove into her pussy getting at her as much as possible. With her legs constricted by her jeans she couldn't spread her legs but I was able to lick her and nuzzle her.
