You must remember this, a kiss is still a kiss, a sigh is just a HEEEUUUUURRRGHH!
At college, I had a couple of acquaintances – Simon and Nicky. They were doing the same course as each other and so hung about together a lot. And went to student parties a lot, too.

One party saw the two of them getting a bit drunker than usual, and indulging (unwisely, as it turned out) in a little bit of tonsil hockey in the middle of the kitchen. Tongues probed, bodies entwined, hands wandered; people looked on, slightly bored. Contented sighs and heavy breathing emanated from Nicky as Simon snogged her more and more enthusisatically... And then it happened. Nicky’s last vodka decided that it didn’t want to want to be processed and ejected the normal way and made a determined bid for freedom via her mouth. Which was firmly attached to Simon’s at the time…

The look of startled horror on his face as his he suddenly found his own mouth rapidly filling up with someone else’s vomit was, frankly, both horrific and hysterical at the same time. I’ve never seen someone run so fast to the bathroom in all my life.
