Mio applies to test a beauty treatment before a beach trip with her boyfriend, unaware that the spa preys on innocent women. The staff coat her pale body in aphrodisiac oil and relentlessly massage her groin, fingering her drenched pussy into repeated orgasms. While she lies trembling and dazed, a cock penetrates her. Though she hates it, the drug-fueled pleasure drives her into a broken, urine-soaked climax unlike anything she has ever shown her boyfriend, swallowing her innocent mind and body in wave after wave of ecstasy.
