Unable to forget the sensation of "Bondage" she received from her deceased husband, widow Saki would wrap hemp ropes around herself and indulge in masturbation. Though she reached climax by pressing the hemp rope into her crotch, she felt an unfilled void in her heart, so she decided to visit Douyama, the master from whom her late husband learned bondage. The tighter the hemp ropes bit into her body, the more vividly her memories of her husband came back. Bound by Douyama and intoxicated by the ropes, Saki transformed into a female dog being trained, naked and collared.
The one who stepped forward to bind Saki in place of her deceased husband was a young man, a disciple of Douyama. Bound by a man younger than herself and exposed in a humiliating position, Saki's masochistic blood stirred as she shook her hips, becoming a complete female dog. Her H-cup breasts bounced wildly out of the bondage ropes, and the moment she took the erect dick in her mouth, it was thrust all the way to the back of her throat. With her womb aching and legs spread, Saki was pounded deep into her vagina while gasping from the torture of having her neck choked and breathing cut off. When her hips were grabbed in cowgirl position and she was ground wildly, convulsions wouldn't stop and her hips broke down into a wrecked state. Her bare pussy was stained with white cum, and she showed an ecstatic expression.
Bound tightly all over her body, Saki fights against the approaching orgasm. Her entire body becomes an erogenous zone, and she feels like she's about to cum any moment. When her wide-open, blood-engorged pussy is slurped noisily, she screams and her consciousness fades, followed by a moment of silence. Soon, squirt gushes from her pussy making vulgar sounds, and Saki, driven mad by pleasure, clings to the new man's big dick and won't let go. After climaxing many times on the big dick shoved deep into her vagina, Saki becomes blank and stops moving like a doll.
