A Mouthboni is when a person ( male or female) performs oral sex on a male after intercourse ( anal or vaginal) and cleans the excess sexual material from tip , shaft and balls. Very similar to a zambini in ice hockey.
I was banging this girl in the ass and when I pulled out there was seaman left on my cock so I shoved it in her mouth and she gave me a Mouthboni. M15
