She doesn’t let you out

As the day goes on, you remain in one of Kim’s bloated balls as she goes about her business. Luckily for most of the day, there wasn’t much action involving you, except for the occasional boner Kim had to suppress. You could tell by the increased heartbeat all around you. Blood rushing in to bring your big sister’s massive cock to full mast. She never relieved herself, however. Maybe she was waiting until nightfall to let you out without raising suspicion with the rest of the family. The level of pungent seed around you had risen throughout the day. At first the cum-level remained around your thighs. Now, it was sometime in the afternoon you predicted, and Kim’s sperm was up past your bellybutton. This was mildly concerning. Rising liquids in enclosed spaces was definitely nightmare material. Was it possible to drown in here? Or perhaps there is always a bit of breathing room for a tiny person like you to breath in?

Halfway through your panic-ridden thoughts you whole world is shifted. Throughout the day Kim’s balls had swayed on their own naturally, but this was different. Kim had grabbed the ball you were in, massaging it. This caused you to slip and slosh around inside your cum sauna.

“Hey what’s the big deal, Kim, what are you doing out there? Cut it out!”, You cry, not knowing if Kim could even hear you through her own ball flesh. Surprisingly, she responded. “Calm down little bro, it may be your new room, but it’s still my nut.”, She smirked. You could almost see the smug smile that resided on her face as she said that. But wait, did she say ‘your room?’ “Kim, what do you mean my room? Are you going to let me out tonight? I’m done playing inside your balls, h-how about I play with the outside now?”, You nervously try to barter. Deep down you fear what this means but you don’t want to believe it. Surely not, right?

“Sorry little bro, but I’m keeping you in there. You feel too damn good to let out.”, Kim responds to your inquiries. “Plus Mom and Alice know you’ve shrunken down and are looking for you, I don’t think they have anything better than the situation you are in now in mind. Mom says she’s hungry and Alice was mentioning butt stuff, so I’d say you’ve got it good inside my sack. Protection, food to eat, and you get to pleasure your big sister! What’s not to love?!”

You are motionless as you consider the situation you are in. Did Kim just say the rest of your family wanted to essentially eat you? Into both ends, too? My god, maybe she’s right. Somehow in this messed up situation, the best and safest place to hide is inside your older sister’s ballsack. “Consider it a testament to how much I love my younger brother, protecting him inside of my own balls. It’s so cute and honestly hot.” She giggled. You could hardly understand your situation. At least living in your big sister’s cum factory beat being eaten alive. The ball you were in continued to jostle around as Kim fondled it. Her cock soon grew to full length. “I’m heading to the bathroom, I think it’s time for you to get to work little Bro…” Kim purred.
