Saki Hiiragi arrives at a hotel room and obediently undresses and puts on a collar as instructed by the man. As a greeting, she licks his feet, receives spanking, and immediately her masochistic switch is triggered, causing her to act like a submissive female dog. With a hook in her nose, she exposes her shame, urinates, then is taken doggystyle and made to receive cum in her mouth. Bound tightly and continuously stimulated with a vibrator, she reaches multiple orgasms, and as punishment for coming without permission, she is slapped, has a dildo violently thrust into her throat, and is seared all over with hot candle wax while enduring relentless domination. Even as tears and snot stream down her face, she is mercilessly choked and fucked. With eyes rolled back, climaxing repeatedly, Saki surrenders completely to the pleasure of sadomasochistic torment, delivering an ultimate, intensely erotic scene.
