Awhile back I was living with a roommate who had a pretty smoking hot girlfriend. The girlfriend was nothing compared to her sister though. The sister, who we'll can Sandy, was a smoking little hot brunette with huge tits and a tight ass. Well she was over one day and they all announced they were going to the pool for awhile. As much as I would have like to see those sisters in their bathing suits I decided to pass. As they were getting ready to leave I noticed Sandy place her gym bag on the floor of my roommates room. At this moment I was very glad that I decided not to go. They left for the pool and I watched them walk away from the window and then made a beeline for that bag. I opened it up and found my prize. Inside were a black bra and thong that Sandy had been wearing before she changed into her swimsuit. I first took out her bra and thought that just moments ago her beautiful 36C sized tits, per the tag on her bra, were resting against that fabric. I then grabbed her sexy black thong and headed back over to my room.
Once inside, I stripped down and sandwiched my now very hard cock between the cups of her bra, wishing that they were instead her tits rubbing on my dick. Pumping furiously I took her thong and brought it up to my nose, breathing in the beautiful scent of her pussy. It smelt sweet with just a hint of musk and urine. With all my might I briefly stopped stroking and placed her thong over my head so that my nose was resting on the thin strip of fabric that just moments ago was resting over her ass hole. Resuming stroking my dick I took a deep breath of her sweet ass hole. At that moment I started to shoot load after load into her bra all while the lingering smell of her ass assaulted my nose. After what seemed like an eternity I came down from my come and removed her bra from my dick and her thong from my head. Turning her thong inside out I used the crotch area to rub my cum into her bra. I then placed both items back into her bag as I had found them. When they returned from the pool they announced that they were going to the movies and again I declined. As soon as they left I ran and jacked off again thinking about her sitting through that movie with my cum rubbing against her tits and pussy.
