I was a literal cumdump [F]

At my brothers wedding I went to the bathroom and a guy was in there jerking off. I obviously caught him off guard, told him to keep going. I could see his cock was pulsating, so I dropped on my knees and opened my mouth. He came so much it overflowed from my mouth.

I got up and left and used the outdoor toilet instead.

Turns out he’s my sister inlaws cousin. Lunch the next day was awkward
