Hot, supple dark flesh bore down on Gina from all sides, squeezing her puny naked body as she struggled to get free. The rippling flesh was smothering her, pushing the air from her lungs and threatening to crush her fragile form. The pressure inside Penny’s asscheeks was intense and it only seemed to be getting worse as she tightened her soft, but well-toned booty around her former friend to punish her helpless form. Her big breasts were compressed against the wall of ass flesh and her hair was a mess. Gina was sure she probably looked terrible, but at least she looked better then most of the other things that came out of Penny’s rump. Thinking about what else might be passing through this wronged giantess cheeks made Gina shiver in fear and desperately look for a way out.

Gina tried to move out of Penny’s crack, first trying to go up and then forwards, but the grip of the doughy walls around her was too tight. Penny continued to hit her cheeks, the jolting made it even harder to come up with an escape plan. As the cheeks vibrated around her and she was jolted around, the pressure and heat made her feel a very strange.

“How do you like my ass girlfriend? Ace sure loves it, I bet you let him fuck you up your loose bottom.” Penny teased, her full rump in the air as she gave it another smack. The tiny body between her buns was barely moving now, either because Gina realized that she wasn’t going anywhere or part two of her revenge had already started. When she felt Gina twitch she knew that the second part hadn’t begun yet, which was fine with her. She wanted to enjoy playing with Gina while she was still able to move.

“Now what shall we do now. Maybe I’ll take a long, relaxing nap on my stomach after working so hard. How does that sound?” Penny giggled when she felt Gina start moving again. She was probably saying something too, but with several thousand pounds of ass fat pushing against her tiny voice was completely muffled. Gina kept squirming until Penny squeezed her chocolate buns tightly, making the girl stop immediately. Penny reached down and rubbed her big round booty happily. This was about making Gina pay for betraying her, but she’d be lying if she said she didn’t enjoy having power over her little friend. There was a sexual rush that came from having a former rival an ass slave and it was making Penny a little hot. Maybe after this she’d call up Ace for another kind of booty call. He still had to pay, but momma needed her loving.

Gina felt Penny strutting somewhere, but she knew it couldn’t be the bedroom. Penny would never be that merciful. She had a really bad feeling about this and tried to scream out to Penny. “Penny, can’t we talk?” What exactly there was to talk about Gina wasn’t sure. She knew she was in the wrong, but being shrunken and put into Penny’s backside seemed a little extreme. She pushed her hands into the doughy walls against her and tried to push them apart, but it worked as well as squirming and her arms just sunk into the supple dark flesh. Dropping her hands to her side, Gina gave up escape for the moment and just tried to keep from passing out when Penny squeezed her buns around her. If she could keep from getting hurt when Penny brought her ass cheeks down on her, Gina thought she might be fine.

Unhappy to find her ass toy suddenly still, Penny gave her a large squeeze of her cheeks. It got Gina to move a little, probably in pain, but nothing else. Scowling, Penny stomped her way towards where she had been planning to deliver Gina to Hell. “No Gina, you’re not getting off that easy. I’m going to my Rec Room to work out. For the net few hours I’m going to be working my ass and getting really sweaty. Those cheeks around you are going to come clamping down and they are going to grind your pathetic body into my fat, juicy butt into nothing.”

That got Gina squirming again; Penny even thought she could feel some tears against the inside of her crack. What Penny hadn’t told her was that although she was going to crush Gina, the girl was pretty much invincible while shrunken. If her body was crushed it would revert to an almost putty like form that would reform to normal given enough time. Penny was pissed, but she wasn’t going to kill Gina, but letting the ittty-bitty home wreaker think so was very cruel and fun.

In her Rec Room, Penny strutted towards the stationary bicycle and sat her Gina stuffed bottom on the seat. She could already feel her cheeks coming together around Gina, putting the pressure on around the tiny girl. Lets see how long Gina lasts, Penny thought as she began her work out.

Gina had been doing everything to escape or hurt Penny. She had kicked, punched, elbowed and even bitted the squashy surroundings, but got no reaction other then small ripples of fatty deposits. She couldn’t move forward or up, so Gina even tried to move backwards. It was horrifying, but if she could hide in Penny’s anus she could escape the next time she used the bathroom. But nothing worked and then Penny sat down to work out and all that ass fat came together around her, squeezing her tighter then ever. As Penny started peddling, her cheeks rubbed together, grinding against Gina. Crying helplessly, Gina wondered how much longer it would be before the pressure popped her like a grape.
