I had picked up this chick, got a slice of pizza & went back to my place where things heated up. One thing led to another and before I knew it, she was on top, riding me cowgirl style. I was giving her some long, hard deep strokes. She moaned and then she moaned some more, and then she gagged... and vomited. The warm chunky treat landed next to me, and ran under the waterbed mattress. She was really embarrassed, jumped off and ran to the washroom and asked me to take her home. AS I was driving her home, she told me that she was lactose intollerant and had forgotten her pills.
When I moved 7 months later, the vomit that I had missed was still moist under the waterbed mattress.. and still smelt as bad as the day it was deposited there!!
