I was sharing an apartment with a quiet, reserved guy in his early 30s, John. It was a luxury one, a little above my budget, but had a spa, sauna and pool in the complex.
It was a Friday night and I was getting dressed to join my girlfriend at a party and was looking for my sexy black thong panties which would go well with my little slinky black mini-dress. I looked all over my room, but couldn't find them. As it was getting late I put on my only clean pair, a white one.
I arrived at the party and Liz was already there chatting with a couple of guys. When she saw me she beckoned me over and introduced us.
It turned out the guys were gay. Most of the others there were either partnered or single women. So Liz and I decided to leave and we headed back to my place. We were both as horny as each other and as soon as we got into my room I pushed her back on the bed and slipped my dress of.
"Those panties don't exactly go with that dress." She observed
"I know, but I couldn't find my black pair."
"I bet your roommate pinched them!"
"What?"
"My brother used to pinch them from me and masturbated in them. Is your roommate in?"
"No"
"Well, let's go in and look, shall we?"
We got up and went into his bedroom. It didn't take Liz long to find them. They were in his bed half under his pillow. On the floor were a few porno magazines depicting bondage, she-males and girls in panties and some hard core DVD.
"John has certainly been enjoying your panties. They are full of cum stains."
We took them back to my room. The thought of him using my panties for sexual gratification really got me going and our lovemaking became intense as we 69'ed-our tongues deeply penetrating each other's pussies and also pressing the tips of them against each others clits until we each had several orgasm.
The next morning Liz had to leave early to pick up her husband on the red-eye who had been away on business and I fell asleep to wake up about 9AM to hear John in the kitchen.
I put on my panties and my dressing gown and picked up the black pair and went out to the kitchen
"Good Morning." I said, throwing them at him while he was sitting at the table eating his breakfast. He went all red in the face." You little pervert! Getting your rocks off with my panties! " My voice was raised at this stage.
