Rize wants to get into Kaneki's ass

Kaneki gulped as she spoke. Surely she didn't mean . . . was she going to try to fit that monster in his butt?

Rize answered his question by having two of her tentacles grab Kaneki's legs. The slowly lifted them up until Kaneki was dangling in the air with his legs up, his cock jutting towards the sky, and his virgin asshole pointed straight at Rize.

Rize spit on her finger once before she placed it at the entrance to his butt. She rubbed her finger around his hole, applying slight pressure as if she were giving him a massage. Kaneki couldn't deny how good it felt and another drop of pre-cum leaked out of his cock. The small bead of cum ran down the his shaft and slid towards his ass.

Rize took notice of the bead of cum traveling towards her fingers, and raised her hand towards it. She scooped up the pre-cum with her finger then smeared it all over his hole. Then, with zero warning, she shoved her finger into his ass. Kaneki let out a screech at the pain caused by the sudden intrusion but Rize clamped a hand over his mouth.

"Don't be such a baby. If you scream like that someone might come to investigate. Besides you have something a whole lot bigger coming your way soon so you'd better be able to take a finger no problem.

Kaneki had been feeling many things up until this point, but the primary one had been pleasure. When he felt the pain of her finger entering his ass though, fear quickly overwhelmed his lust. He couldn't imagine how painful her cock would be.

He would soon find out however, as Rize placed one hand on her monstrous cock and lead it to Kaneki's virgin ass.

"Try to loosen up for me as much as you can, won't you? I'd hate to have to **** myself in." Something in her tone told Kaneki that that was exactly what she wanted to have to do, but Kaneki tried his best to relax his ass regardless.

Kaneki felt her warm cock head press into his asshole, but even the tip was too large to fit. Rize applied more and more pressure before finally, the tip of her hard dick slid into Kaneki's ass.

His hole had been streched wide to fit her cock. And it burned unlike anything he'd ever experienced before. But at the same time, Kaneki's cock was harder than it ever had been.

Rize slowly fed more of her cock into Kaneki's ass. Each time an inch of her cock made its way into his tight hole, Kaneki thought that there could surely be no more, but her long dick continued to enter his ass. After what seemed like an eternity, Kaneki began squeezing his ass as tight as he could. He couldn't bear to take anymore of her at all.

Rize let out a loud groan as she felt him squeeze her. "Kaneki save that for later, I want more than half my cock is in you right now." Kaneki's eyes shot wide as she said that. It had felt like an eternity, but only half of her was inside his ass? Despite her comment, Kaneki continued to squeeze his ass, trying to **** her dick out of it. If this was only half of her massive penis, surely the full thing you just break him.

This was apparently the wrong move however, as it only seemed to encourage Rize even further.

"That feels so damn good Kaneki," she said as she increased the pace as which she shoved her dick into his ass. It wasn't long before she had managed to fit all 10 inches of her massive girl dick into Kaneki's ass.

The lack of movement provided some small relief for Kaneki, but his ass still burned with unbearable pain. He didn't think he would still be sane by the end of this.

Kaneki's relief was extremely short lived unfortunately, as Rize almost immediately began to draw her hips back, snaking her dick out of his ass. It was a much smoother process this time, and it wasn't long before only her tip was resting inside his ass. Rize than quickly thrust two more inches inside of him.

As she did so, the tip of her cock brushed against the wall of his asshole, and a spear of pleasure shot through Kaneki's body. A load groan left his mouth, which was still covered by Rize's hand.

"I guess I found your prostate, huh," she said. She didn't say anymore however, as she quickly began to thrust back into Kaneki's ass. By the time she was fully hilted in him once again. Her breath was raggedy, and her cock was throbbing unbearably.

"You feel incredibly. So fucking tight and warm. I can barely control my hips." Rize's voice had lost all sense of mockery at this point. She was completely consumed by the pleasure. When she drew back this time, it was much faster. Her cock then quickly slammed back into him.

Rize began sawing in and out of Kaneki's ass at a much greater pace, as she was properly fucking him now. Every time her cocked stroked past his prostate, Kaneki's cock would give a small jump and a groan would escape his mouth. His asshole was constantly flexing around Rize's cock, squeezing it tight and giving Rize incredible pleasure.

Rize's hand slipped away from his mouth and towards her his hips. She grabbed his hips with both hands and began thrusting even more fiercely. Loud, uncontrolled moans began leaving her mouth as she thrust, and Kaneki's period yelps of pleasure joined her voice.

"I'm gonna fucking cum in your ass. Your virgin ass is having me cum so quick!" Rize shouted out as she thrust. Her cock thrust erratically in and out of Kaneki's body. She was completely consumed by pleasure and was seeking her release.

Rize's dick entered Kaneki's body with particular **** and slammed against his prostate, causing his ass to tighten even more around Rize's thick cock. Rize let out a drawn out moan and thrust once more into Kaneki's body. All 10 inches of her hard meat were lodged in his ass when she began to cum. Large spurts of semen filled Kaneki's ass as groans left Rize lips and Kaneki's ass squeezed her tight.

Her orgasm seemed to never end as Kaneki felt the 7th spurt enter him. Eventually, the loads of cum she dumped into him decreased in size, until they were little more than a trickle of cum.

Rize slid her sensitive penis out of Kaneki's ass, then collapsed on the ground, her tentacles releasing him as she fell back.
