F4M Your girlfriend’s Mom’s husband (your GF's Dad) ran out on them so YOU moved in and stepped up as the MAN of the HOUSE - which included paternal duties such as MAKING her Mother CUM like a FILTHY WHORE while she SUCKS your COCK. But suddenly her Mom's deadbeat husband is back. He’s planning to wine and dine her but you feel the need to have her Mom for ONE LAST FERAL FUCK. Nothing like leaving your girlfriend’s Mom, SPENT and RUINED on the kitchen floor, only good for sloppy seconds.
