I (M) had a roommate in college that was a random person my normal roommate had subletting his room for the summer. I was going to be staying there too and it would be just me and this random all summer. I met her first when he showed her the place and I was immediately absolutely floored by her. I couldn’t look away. She was a stunning brunette with gorgeous deep brown eyes. She worked out almost every day so she was perfectly toned and fit. I couldn’t stop thinking about her but we weren’t really friends and we didn’t know each other at all. We had opposing work schedules so we didn’t see each other all too often when we were home, but when we did she had so little regard for what she wore. I thought at first she was trying to show off on purpose so we could hook up, but she was always pretty cold towards me or just rejected anything I put out, like “hey let’s watch a movie tonight” or anything.
She would walk around in only a towel (and it was no beach towel, you could see the curve of her ass and the tops of her breasts as she walked back to her room) or a T-shirt and panties. It was torture to not be able to do anything with her. Well one day I decided if I couldn’t have her I was going to have the next best thing. I snuck into her room and grabbed a pair of her panties and used those to get off while thinking about her. She would never know, what was the harm? I did this a couple times and even did it on her bed a few times too. She never found out and it was never even close. I wouldn’t cum in them so there wasn’t even evidence. Well until one day I decided to take the next step and cum in her lace thong. I was so hard while thinking about her I could barely contain myself. I was on her bed with her thong wrapped around my cock and i came all over them. Then of course as I’m cleaning up I hear her keys in the door. I sprinted back to my room after throwing her mildly cleaned panties back into her drawer. She never said anything about it so I assume she never found out, but the thought of her wearing my cum around all day pressed against her crotch was enough to get me going again that night
