This is not a pukestory, but I think it'll do...
Several years ago (about 6) I was coming back from a party with a girl.
We a good deal: She was my fuckbuddy and I called her my "Gothmattress". (to my experience, goth girls are quite kinky) No relationship, just sportfucking when she's not on her period. It was great!
Back to the evening.
We were sitting in the bus, on the backseat. We kind of couldn't wait to get to my place, so we figured we'd do "manual good" to each other. I opened my zipper for her hand and tuck my hand under her skirt. (we made sure no one could see)
In the middle of our ride a guy I knew came in with a friend of his. I was a gentleman and introduced my date and we exchanged a few words. I didn't know the guy that well, so we didn't keep up an uncomfortable chat. Besides, the guys noticed that we were a bit drunk and kind of left us licking eachother's faces.
After a few weeks I ran into him in a roleplaying store. (our mutual hobby)
I mentioned I remembered seeing him in the bus. He was like "You and that gothchick have good sex later? Cuz you seemed somewhat busy tonguewrestling."
I told him what we ALSO did back there.
That broke the ice between us!
I originally picked her up in a bar with a line "Nice boots. Wanna fuck?". Next morning she told me she was 17.

(I was around 21 then)
These days he's one of my best friends.
BTW, remembering now, I think she introduced herself as "Flaymin's gothmattress" in the party...
