While holding in my piss, I hard-fucked her and broke Heart-sound girl! Just like a morning boner, when you've got to piss, your sensitivity is through the roof! Tightening uterus, accumulating urine and uterus, swimming internal ejaculation sperm making her 'Cumming cumming～♪' Legs buckling, super cumming non-stop! Ecstatic face repeatedly & losing strength, pissing herself b-b-bursting! In the limit state of three rounds of internal ejaculation, I transformed Heart-sound girl into a sensitive body☆
