START-257 | After a drinking party, I had a one-night stand with a colleague I didn't like, and the fit of his dick in the back of my vagina was so good that I experienced the greatest orgasm of my life... Even though I didn't like him at all, I had sex with him again and again.

As they get worked up and start to insult each other, an unexpected development occurs: "If you say so, why don't you try it!?"
