30-year-old Iroha (pseudonym) is a genuine masochist, said to have blood coursing through her body that's entirely devoted to submission. On the day of filming, she sits tense inside a car driving through the night streets—but she's tense only because she's eagerly anticipating what's to come. Once stripped inside the vehicle, car sex begins immediately. Being intimate while exposed to potential onlookers is a uniquely thrilling experience for her. Later, at a love hotel, they have sex repeatedly, again and again. Finally, invited back to her own home, they engage in one last round. Every act is bareback, creampie after creampie, swallowing cum again and again. Her buttocks swell from intense spanking and candle play, escalating her torment. In the end, every moment unfolds exactly as she begged for it.
