"Uhhhhhh!" she gasped.

He was sliding it back in, burrowing his cock into her body, his balls tight, tense and eager to cut loose into her shitter.

"Ooofoofffffff!" Monica panted as Jack kept going, going past where he had stopped before. Her eyes glazed over as she felt another series of spasms ripple through her body. She kept thinking that surely he would have to stop. There couldn't be much of his prick left to stick up her ass. But he was pushing more and more of it up her ass. Ohhhhh, how much more sensitive her rectal nerves seemed to be than she had ever thought! It seemed that the thick bar of prickmeat pistoning in and out of her ass was growing, growing until it was the size of a baseball bat! He was impaling her, tearing her body in half with his big cock. And still it kept going in, in, spreading apart her asscheeks.

Again, that steady pressure eased. Monica felt Jack's belly against the tops of her asscheeks, and she thought he must be in all the way. The woman let a long sigh escape from around the latex tube gagged in her mouth. Then Jack began pulling back a second time. And again, Monica groaned, her body shivering from that obscene vacuuming. Surely, she felt, he had to be pulling her bowels inside out!

"Nice, good ass, good fuckin' butt," Jack muttered, slapping the backs of her legs, then pinching her asscheeks hard until the woman squealed through her rubber gag.

Monica was going wild as he fucked her hard, pressing her ass back against him. She arched her back like a cat, the odd fullness inside her bowels starting to arouse her more and more. It was a different kind of heat from the one in her pussy. But it was powerful, strong enough to take her breath away! The woman gasped and squealed, wiggling her ass from side to side, feeling her body spread more and more as Jack grunted and fucked behind her.

"Uhhhhh!" she kept moaning.
