Another story from a long time lurker.
A couple of weeks a ago, I stayed the night at a friend's apartment. Actually it was my friend's girlfriend's apartment. We'd been up late watching movies with her and her roommates. We all went to sleep and I just fell asleep on the couch.
In the middle of the night, I woke up and could not go back to sleep. So I got up and walked around. I went into the laundry room where I found a clean load of laundry sitting on the dryer. There were some tank shirts, shorts, work-out clothes and underwear.
I have a total underwear fetish. I love a sexy thong on a girl. I determined the laundry belong to one of the roommates. She is a pretty girl, 5'7'', probably 120lb, dark blonde, blue eyes. The underwear was nice, nothing amazing, lots of cotton thongs and g-strings mostly from victoria secret. Then I saw a black see-through mesh thong with a small flower print.
I became rock hard instantly. I pulled down my underwear and wrapped the panties around my cock and began to stroke right there in the laundry room. It was awesome. I had the tip of my cock right in the crotch on the panties.
I had to make a decision...do I cum in the panties or not. If I cum in them, I'm going to leave evidence. I've j/o into my share of girls underwear but never actually shot my cum into them. The idea of being caught or discovered really took over and I filled her thong with cum right there.
The thong had a cotton crotch which became saturated and my cum leaked through and onto the mesh as well. I carefully placed the panties back where I found them. I quietly went back the the couch and finally fell asleep. Haha!
