My girlfriend's mother calls me over because her daughter has been acting strangely. Faced with beautiful Maki Koizumi and her enormous breasts, I can barely stay calm. She catches me staring down her top and actually shows me her tits, unleashing a taboo desire I can no longer control. We lick each other in sixty-nine, her breasts make my cock rock hard, and then I push it raw into her shaved pussy. Pleasure makes us forget all about her daughter as we devote ourselves to sex—so why did she call me over in the first place?
