[Minato Mirai (Minato Yuu)] Sperm Buying Service

A shy young man signs up to sell his semen, but panics at the last second—until the curvy, ponytailed milf running the counter presses her enormous breasts against him and coaxes his sample out personally. When he turns out to be a premature shooter who can't keep going, she summons two equally busty coworkers to wring every last drop from him in a relentless group nakadashi session. He stumbles out dazed, fanning a stack of ten-thousand yen bills and marveling at a city where three hungry women draining him dry pays this handsomely.
