A first-time spa experience unexpectedly turns into an NTR scenario! Rikka visits a couples' spa to buy a cute swimsuit for her one-year anniversary trip to the beach with her boyfriend. However, the shop, contrary to its reputation, is a shady establishment targeting frivolous couples. With her boyfriend right next door, she's coated in aphrodisiac oil, becoming slick all over and succumbing to convulsive orgasms. Unable to make a sound, her rationality is swept away by waves of pleasure, leading to a creampie r●pe. Once loyal only to her boyfriend, Rikka falls under the cunning techniques of an older male therapist, reaching a climax where sweat, drool, and fluids burst forth like a dam breaking. Repeated injections of aphrodisiacs and semen transform her into a lewd pussy that actively clings to another man's rod—a shocking narrative. This work portrays a drama intertwining guilt and ecstasy through realistic acting and tense developments, captivating viewers. Having watched it myself, I was breathless at its pursuit of erotic extremes.
