Bust a fat ass nut 

When you cum so much that it could cover a fat ass.

Guy 1: Aw shit I’m about to bust a fat ass nut in your tight pink pussy

Girl 2: Yeah fill me up with your warm cum daddy. Fun fact: Since you said fat ass in that sentence you’re implying that all your cum could cover my fat ass.

Guy 1: Wow, I didn’t know that *cums fat ass nut*
