Stuck In Athen's Balls. [WM]

After she sunk down Athen's urethra she eventually popped into a more open space slowly filling with cum. Was this one of her balls? It was tight but not as tight as the urethra she was just **** down. She banged on the walls of her fleshy prison, called out, and kicked around. Nothing worked, if anything she was pretty sure it caused Athen more pleasure. It also seemed like when she caused Athen pleasure cum production increased. Shit. She should probably chill out for now. The smell was so strong, that she wished to be able to smell anything else.

She could only lay in her prison, bathing in cum, unable to do anything else. It felt like several hours already and she knew that she was just **** into this hell. There was nothing left for her to do but wait for Athen to cum again, that was her only chance at escape. So for now she laid there lethargically, in Athens cum, haven given up for now.

Time became blurred together as Zorin remained trapped in her little sister's balls. She was pretty sure Athen was intentionally keeping her in there for a while. Throughout the day she felt her cage get turned upside down a couple of times. She assumed it was Athen teasing her. When she felt such things she tried her best to pound on the walls and scream. It never worked. At one point she thought she heard Athen say something like "Having fun, big sis?", how cruel. She once again tried her best to beat at her prison to no avail. Instead, it only earned a moan from Athen. "Fuck!~"

There was one point after Zorin had been there for a while when her "cage" got tighter, restricting her further and the cum production increased. What was Athen doing!? Watching porn?! She could tell Athen was partly doing this just to **** her and tease her. There was a small part of her that was aroused by these events but her discomfort triumphed over those feelings. Her prison remained tight like that for a while. Eventually, everything became unbalanced as if her prison was being pushed around by water. Was Athen in the bath? This couldn't be good.

Cum began rapidly filling her prison. She was going to drown! She tried to escape, **** her way out. But the only thing she accomplished was causing her sister more pleasure. She could hear her moaning from in here! Athen was getting ready to cum, this wasn't going to be fun. It would however be a chance to escape her little sister's testicles. She would escape! She thought she heard her sister moan something specific. "I-I'm cumming!~" Oh god, here's her chance!
