This happened in college.
I know what I did probably isn't kosher but who gives an F. I was horny.
At my college the buildings are divided up into apartments. On my floor if I step out my door there is a door to my left into a tiny laundry room with one washer and two dryers. The other day I went in there to start some wash. No problem. Washer was empty. Load it and start it. It's just me in there and I notice one of the dryers is full and finished. I open it to see if it's one of my room-mates. It was not. It was all women's clothes and women's underwear.
Some nice lacy thongs and booty shorts also in lace. I had no idea which girls in the building they were but I looked them over and started getting hard. I do not know what came over me but I grabbed a black and pink thong and a red pair that were like a thong and booty shorts in one. I jammed them in my sweat shirt and went into my room of the apartment. As soon as I got in my room I locked the door and stripped off my clothes I was instantly hard. I decided I would let my cock soften then try on the sexy lace underwear I had nabbed.
Once my erection had subsided I slid on the thong. It felt amazing it barely held my cock and balls with the minimal lace and the back was a tiny string that led to a lace triangle. I immediately began to stiffen. The feeling of the lace on my skin was erotic. I pulled it off and once again had to let my erection go down. Once it was soft I put on the red lacy hybrid thong. There was a bit more room for my cock and balls. My upper ass was covered while my cheeks hung out the bottom with the material in my ass crack. I was so horny I jumped on one of those cam sites where you get a random person. I was amazed how many guys mistook my ass for a chicks and were surprised when I turned around revealing my hard cock. I eventually tired of this and went to some porn. I just loved the feeling of the lace on my body. I stroked to a massive cum and hid the panties in my next load of wash. I kept them the next few years. I understand why women love lingerie you just feel like pure sexual energy.
I stole a few other pairs of panties that year. Have not had the opportunity to do so in a long time.
