When a chick is sucking your cock and you notice insane amounts of jizz oozing out of her loose, overworked snatch. Because we are guys, we continue on face fucking her and dump the contents of our balls into said bitches gut.
Dude, really. Your mom is a filthy slut. I mean, she sucks a good dick and all but holy shit she's a total cum dumpster. How many guys do you think she fucked already today? I'm guessing by the amount of jizz i saw seeping out of her loose flappy twat and asshole, that she's been with 8 or 9 guys already today. Have a talk with her will ya?
