During a training camp at an inn, a kind senior female manager helps a troubled junior male member improve his premature ejaculation through mixed bathing. It's also the female manager's job to solve the junior member's penis problems! She uses a hand-free blowjob to strengthen his premature ejaculating penis. The busty manager, who has become hot from the hand-free blowjob that makes the virgin penis erect again immediately after ejaculation, gently rides and inserts it for the first time.
