Max moved the blade again, pressing the flat end of it against her shifter and rocking it down until the sharpened ends cut into her asshole. Lydia snapped her head up, feeling a spasm rattle through her cunt while air escaped from her overheated cunt.

"So, you like it that way, huh? You're even fartin' because you can't stand it," Max laughed.

Lydia was shaming herself, she knew. Turning partially around, she could see Max stroking himself, greasing down that long meaty prick with the jizz oozing from his piss-slit. She licked her dry lips, feeling her throat tighten even more as she dragged in another raspy breath of air. Oh yes, yes, she would have given anything to have him fuck her… fuck her just the way that knife was toying and fucking her! She wanted to have that animal jam his cock into her hungry cunt. The slick, itchy tissues were aching for his touch for that rub of his cock-meat. She could almost feel her cunt stretching itchily around that fat prick jerking behind her.

He was poking the blade against the rim of her whole. Lydia gasped at the touch, jerking her ass back. The itchy stabs forced the slick ring of her shitter inward. He was breaking the wrinkled skin. For an instant the woman closed her eyes and groaned, letting herself imagine how it would feel having his cock up her ass!

Max was panting heavily now, still jacking off. His fist moved like a piston over his prick, the dark-blue veins throbbing and standing out against his cock-skin. He was poking the tip of the knife into her puffy cunt-lips, sliding the weapon then into her ass-cheeks. Lydia thought she would die feeling so good, so shamed, bound and yet free. The woman shook her head, rolling her hips from side to side, arching and thrusting her lush ass-cheeks back at him.

"Yeah, that's it, move that ass!" Max whispered, backhanding her ass-cheeks with his fist, then bringing the knife back against her ass-cheeks.
