Please read pts 1,2 and 3 first

Soon the one filling her cunt pulled back but a minute later she felt something else forced inside. It then expanded and expanded, stretching her more and more, making the arm still flexing in her ass feel even bigger. Unable to hold back, her greedy ass rippled as her cunt gushed yet again and whatever it was in her continued to grow bigger. The arm pulled from her asshole then she felt something else, something small, being dragged up inside her ass. Then it vanished and the thing in her ass quickly expanded, splitting her asshole as it got ever bigger, bigger than the fists ramming into her, bigger than the man's arm that tore into her, giving her so much pleasure. And still it got thicker, longer and harder. As she came over and over again it finally stopped expanding. It was so big and so far inside her belly she looked like she was pregnant with a log. As a hand pushed against her belly her cunt clenched again. She stayed like that, constantly dripping blood from her ass and juice from her abused cunt. Every so often she felt her cunt and ass and belly expand as the things expanded further.

Finally the vehicle stopped and she fell asleep, with her hand on her cunt.

When she woke she quickly realised she was on a dias of sorts with several huge posts and ropes around her. She heard voices and saw several men watching an enormous screen to the side. She could see enough to realise they were watching while Danny fisted her for the first time. The men watched and commented, seemingly pleased, esp. when the screen changed to the back of the van. Her cunt and ass twitched and clutched at whatever was filling her so full and she moaned. The men looked at her and one spoke into a handset. A second man walked towards her, did something in her ass and cunt and whatever had filled her so gloriously began shrinking, before finally being pulled out. Izzy whimpered at the empty feeling as she was turned on her belly, her arms and legs spread wide and loosely tied to four of the smaller stakes. Her head was held in place by a wide band.

Izzy sensed someone was approaching and she felt a weird huffing noise. She felt a cock at her bloody stretched asshole but it felt hot and odd. Before she could process it there was a loud grunt and the biggest cock she could imagine tore into her as the men cheered. It rammed in and out of her ass with inhuman speed, forcing her to scream but it didn't stop. She could feel damp breath on her back. The ropes gave her enough leeway to allow her to half lift onto her knees, allowing the cock even deeper. As she screamed and came, she felt hot breath on her back and snorts but the cock kept splitting her and pounding furiously. Bucketloads of burning hot cum flooded her ass and poured down to her cunt, down her legs.

As she hung in the ropes she looked over, two of the men were glancing her way but the others were avidly watching the big screen and fisting their own cocks. Suddenly she realised what she was seeing on the screen.... a four legged creature, like a centaur, humanoid in front but definitely not human!! Gobsmacked she hung against the ropes before realising she didn't care. It was the best cock she'd ever had. Incredibly powerful and strong. Just thinking about it made her ass ache to feel it again. Her empty cunt dripped for it. Next thing she knew two men undid the strap across her forehead, then the rope around her ankles before flipping her over and replacing the rope.

The creature returned. It walked straight up to her, nuzzled her cunt then used a small arm to pinch her clit hard enough for her body to arch off the stage. It moved forward and impaled her on it's cock, thrusting so viciously the band holding her head snapped

The creatures secondary, equally thick cock powered into her ass as she screamed and pushed back, trying to get them deeper. It used her holes mercilessly over and over again till the floor was flooded with cum. The creatures cocks didn’t soften after it jetted into her holes, it just continued brutally using her.

Izzy had gushed so much fluid it was almost a pool but her reformed body had limitless juices now. It had to, her holes needed to be fully ready at all times. Cock always using her holes, forcing her to cum again and again.
