The pressure of the sweaty, moving cheeks still pressed down on Gina, but her bones no longer cried out in pain. In fact, she could barely feel them right now. She was still being crushed between the moon-sized ass cheeks, but her body no longer cried out in protest as they pressed down against her. Maybe her body had gone numb or Penny was relaxing her cheeks slightly to give Gina some relief. It probably wasn’t the later, the angry bitch wasn’t going to show a bit of mercy. Still, Salty, thick ass sweat covered Gina from head to toe and it really stung her eyes. She tried to wipe it away, but when she tried to reach up, she couldn’t because her hand had been flattened against Penny’s ass cheek. Gina looked in horror at her one-dimensional hand and then started at the rest of herself. She hadn’t been wrong about her chest, it was flatter as was the rest of her. The hard rubbing and pressure had started to mould her into the inside of Penny’s right ass cheek.

“Yes! I knew that crazy cunt wouldn’t really kill me!” Showing joy since being shrunken, Gina took her small victory as they the left ass cheek continued to grind her into the right. This was a nightmare for her, but at least it wasn’t a death sentence and she could take solace in that. Gina was a smart girl and she knew that if her body was no malleable, she was going to live through this workout. Then it fully sunk in. She was going to live through being in the hot sticky ass crack of her African American friend as she worked out, surviving every single abuse Penny could dish out. Penny could do anything she wanted without fear of killing her now. That good feeling Gina had died instantly.

“Have you figured it out yet?” Penny asked as she shifted her big booty around on the bike seat as she picked up the pace. She could feel Gina starting to melt into her cheek, the tiny body between her mighty buns getting smaller as it flattened out. Penny would miss feeling Gina squirming back there, but she’d enjoy knowing she her new fate on the inside of her ass. “You’re going to live through this, but you’re waistline isn’t going to be the same as when you went in to my ass sauna. I’m going to flatten you into my asscheek, like a tattoo, at least you’ll be a tattoo at first. All that heat, sweat and rubbing of my cheeks is going to make that soft little body of yours even more pliable. I’m going to reduce you to a smear on the inside of my ass crack and see how long you stay. You thought being tiny sucked, try being a stain inside my fat ass.”

“Wai…” Gina was cut off as Penny tightened her buns and lifted herself up off the seat and begun peddling faster then ever before. Her buns started moved together fast, pressing Gina’s putty like body further into her cheek. Gina tried to scream, but the flesh pressed down on her tightly, getting into her mouth as she tried to beg for mercy. She tasted the sweaty ass flesh as her entire back flattened out against the doughy cheek. The back of her head started to go soft as the pressure wouldn’t let up. Gina could feel herself losing her shape, becoming unable to move as she became ingrained into the inside of Penny’s ass cheek. Was Penny really planning on reducing her to a smear on the inside of her ass cheek? Could she ever do that, even with magic? It would have made Gina throw up, but her stomach was rapidly becoming paper-thin and soon her throat would be too.

Penny was bouncing as she rode on the bike, her ass hitting the seat hard to help give her prisoner a little help getting into her new position in life. She really hadn’t thought of how long she was going to punish Gina for, reducing her to a smear seemed pretty harsh and she had thought that after a few hours of being a stain inside her booty would be enough for Gina and her revenge would be complete, but now she was finding this so hot and fun. She thought she would just feel satisfaction in getting revenge on her traitorous friend, but knowing that Gina was inside her ass, being reduced to paste against her cheek gave her a thrill she never expected to feel.

Maybe Gina needed to be punished for a little longer. As long as the pressure and heat inside her ass remained around Gina, she wouldn’t reform. Penny could keep her up there for as long as she wanted. She imagined spending days with Gina unable to move or speak, only feeling her other ass cheek rubbing against her. What would she experience when she went to the bathroom or farted? It would make Gina’s time shrunken whole in her butt seem like Heaven.

“I need to see her.” Penny eagerly exclaimed as she hopped off the bike and rushed towards the closest mirror. She could no longer feel Gina back there, which can only mean that she had been reduced to the first stage. She pulled down her bicycle shorts and parted her cheeks slowly, the smell of sweat came from her damp cheeks, but Penny was focused on something else. She let out a high-pitched laugh at the perfect tattoo of Gina Digger on her right ass cheek, a look of horror and disbelief frozen on her face.

Gina had been unable to move a few minutes ago. She could feel herself being rubbed, but could no longer move. She didn’t realize what had happened until Penny opened up her ass and she saw herself in the mirror. She was completely flat and embedded on Penny’s ass cheek. Nothing about her was two-dimensional. She couldn’t speak or breath, yet she could still smell and taste the pungent stink of Penny’s ass. Penny just laughed at her and then let go of her as cheek, letting it smack back into Gina. Then Penny pulled her shorts up and got ready to reduce Gina to an even worse state.
