What's the weirdest или most embarrassing moment Ты had in your life while having sex?

My GF told me once she had to take a piss, when I was about to cum. I was already deep inside of her. Told her to wait, but she couldn't, so she pissed all over me. That's when I cum.

When I was caught wearing my girl Друзья clothes and talked into have sex with her dressed in lingerie.
