Akari, an adult track-club athlete expected to excel, receives one-on-one coaching during an intensive camp, unaware that her corrupt coach sees her only as a sexual target. He secretly gives her an aphrodisiac, forces deep throat, heightens her sensitivity with an obscene massage, fucks and creampies her, then uses toys on her oil-slick body until pleasure crushes her resistance. The abusive training continues through repeated orgasms and culminates in relentless three-way pounding that leaves her nipples hard, body drenched in sweat, and pussy squirting again and again.
