Overlooking the Creek

My dorm room at my college overlooks a small creek that runs through the middle of campus. Today with the weather being in the high 70s there were lots of girls laying out by the creek in the early afternoon. I ran some errands and returned to my room around four and even though it was still wicked sunny outside there was only one girl laying out by the creek. She was laying out in a short skirt and tank top and had the tank top pulled up exposing her tummy. I thought nothing of it till I looked and saw her legs were spread and she wasn't wearing panties.

I started to slowly get hard and took out my dick and started jacking off when she looked right into my window. The blinds were down but open so I couldn't tell if she could see me or not. She then got up and moved to where I couldn't see her as well so I went to go look at some porn when a few minutes passed and there's a knock on my door and it's her.

I expect her to be really pissed but when I opened the door she pushed me aside and layed down on my bed and spread her legs really wide asking if I enjoyed the view. I instantly got rock hard and said of course I did and pulled out my dick and started stroking it as she rubbed her pussy and pulled her tank up above her perfect tits. Pretty soon I was ready to cum and came all over her face and titties and then rubbed her clit to help her get off. She cleaned up and left and didn't even tell me her name.
