She gets licking, he gets CBT.
By Major Switch
He is on his back on a narrow bench with his wrists are cuffed under, and his ass hanging off. His ankles are attached to a four-foot spreader bar that is tied to a hook in the ceiling. This forces his hips up and leaves his whole bottom exposed and ready for anything.
She has a small soft leather paddle, and she starts whipping his exposed cock and balls. The strokes are just hard enough to stimulate him, and his cock grows with each stroke. She switches from the cock whip to a thin leather strip and flogs his anus. The sensations are amazing, and he begs for harder, until his whole ass crack is red and burning. Finally, he begs for mercy even though his cock is throbbing hard and he's in that altered state where his arousal has consumed his whole being.
She picks up a light wood paddle and begins to alternate swats on each of his glutes. When his ass is a bright red, she paddles up and down his thighs until they are equally red, and he is moaning and squirming
She stops whipping him and puts on latex gloves and lubes his anus. She slides a finger all the way in, pulls it out and slides two fingers in, then three fingers, working his anus to relax his sphincter. She gets four fingers in up to the knuckles and tells him to relax and push because her fist is going in his ass, one way or another. He does as he is told and her fist pops into him. He moans from the pain as her knuckles breech him. When she is inside him, she finds his prostate and massages it, causing a flow of pre-cum. She slowly pulls her hand out of his rectum and when she gets her knuckles back to the anal sphincter, she rotates her fist which creates amazing sensations in all the nerve endings in his anus.
"Are you my loving slave?" She asks.
"Yes, Mistress."
