At a sports-team strengthening training camp staying at a ryokan, a kind senior female manager set out to help a troubled junior member with his virginity and premature ejaculation. After his first mixed bath with the busty senior manager he admires, the junior instantly went fully erect. Seeing that, the manager — despite her embarrassment — repeatedly gave careful no-hands blowjobs to address the premature ejaculation. When his penis remained erect, the busty manager couldn't resist and gently deflowered him, leading to continuous internal ejaculations.
