Making one puke on your cock by the act of fucking them in the mouth very hard until they do so.
I gagfucked your grandmother and when i pulled out my cock was green.

when a guy shits in your mouth and puts his dick in your mouth. After you start to gag on the shit and his jizz. This here looks a lot like chocolate and vanilla icing.
This weekend me and my boyfriend got bored so we gag fucked :)
