In a dimly-lit room, Yoshi's bound by his arms and legs, displaying his vulnerable pussy very accessible to Master Sim, his true master. With his body fully immobile in twisted, knotted ropes, Sim steps on Yoshi’s hole and balls, giving him a taste of what is about to happen. Yoshi watches intently, eagerly, and excitedly anticipates what his master is going to do.
Sim begins with a metal butt plug, the kind that can spread open at its head. Sim slowly, slyly pushes the plug inside Yoshi. The cold sensation invades Yoshi’s rectum till he moans. Sim starts opening the head little by little. Yoshi feels his guts being spread apart as he whines in ecstasy. Master Sim knows his slave is ready for harder, tougher play. He lubes up his fist, thrusts into Yoshi’s hairless pussy. Starting slowly he accelerates the movement, burrows even deeper down his guts. He's rearranging Yoshi’s insides.
Yoshi tries in vain to push him out by prolapsing, but only makes Sim fist him faster and deeper. As Yoshi explodes into orgasm, his eyes roll back into his head. He groans while he squirts himself and soaks his jockstrap.
The Master is not even done yet. He brandishes a thick monster dildo of Yoshi's and shoves it into his throbbing, twitching cunt. The louder Yoshi screams, the harder and faster Sim’s hands take over. With his rose in full bloom, Yoshi obediently cleans the ass juice on the dildo as Sim leaves him convulsing on the bed.
