"How many days has it been?" I ask. "About four days," she replies, a hint of happiness in her voice. Her upper body is bound, one leg hoisted up, leaving her completely exposed. Yukino’s nipples are extremely sensitive—just a touch makes them instantly hard and erect. When clothespins are clamped onto her sensitive nipples, she winces in pain, struggling to endure it. Her nipples become grotesquely distorted, almost cracked, and Yukino lets out a pained cry: "Uuuu~!" With one leg suspended, she’s left defenseless as the vibrator is pressed against her. "Ah, no, stop!" she screams, yet squirts violently, the sound of gushing fluid filling the air. Afterwards, 600cc of glycerin enema solution is slowly inserted into her anus. As the liquid steadily flows into her rectum, she moans continuously, caught between pleasure and pain. *The woman appearing in this video is not a professional AV actress, but an amateur woman who requested enema training.
