Memoirs of My Stunning Girlfriend's Infidelity EP 1

Synopsis

Er Gou is lost in a cuckolding fantasy, imagining his school-beauty girlfriend begging for mercy under his enemy's massive cock, only to be caught in the act by his own younger sister. Sliding into bed with him, she rips off his pants and grips his aching erection with her soft, tender hand, stroking him rapidly. Despite Er Gou telling her to get out, he can't stop himself from erupting, spraying load after load into his sister's hand.
