Riko’s hand reached down towards the nightstand and snatched you up a bit rougher than you were used to. You squeak fearfully as you were yanked towards her midriff, her big belly button peeking out just below the bottom of her shirt.
“Keeping you on the floor was a mistake. I’m gonna keep you close from now on.” She said as her opposite hand reached for the giant waistband of her pink panties, stretching the front of them open. She couldn’t be-
She was though, and before you could object, she released you into the waistband of her panties, letting the elastic go and snapping them shut.
“Mmph, feels kinda funny in there…” Riko said as she rubbed her crotch. Feeling something so small wriggling against her privates was tickling her a little, and her fingers mashed you into her skin until you quit moving.
Having successfully quelled your movement she smiled, patting her crotch as if she were safeguarding a special toy and walking towards the kitchen to grab a glass of water.
Cramped inside of her underwear, you were grinding against her groin relentlessly as she walked. This felt so wrong being rubbed against this young girl’s privates, but she was the one with the power in this situation and you weren’t given any say in where she kept you.
You could hear her running a tap outside of her panties, before chugging her glass of water. You thought the distraction afforded you a little bit of time to wriggle into a spot where you had more room, but her hand that wasn’t holding her cup quickly came down and bullied you again.
“Nngh… Tickles… Stop it…” She grumbled, rubbing against her genitals harder until she felt your squirming cease, before finishing her large glass of water and sighing.
She didn’t feel you anymore through the front of her panties, but she could just barely discern something small that was moving a little further up inside of her now. Her insides gripped the small something and immobilized it, any squirming that she perceived was handled with a reflexive contraction of her groin and instantly quelled.
Riko grinned, feeling powerful and in control as she walked back to her bedroom, shutting her lamp off as she climbed into bed and crawled under the covers. Every now and then she felt a tingle down between her legs as you kicked around inside of her, but squeezing her thighs together seemed to do the trick when it came to repressing your movement for a few minutes. Eventually she stopped noticing you altogether, and quickly fell back asleep.

Hours later Riko was roused again when she felt a tingle between her legs, one that didn’t go away no matter how hard she pressed her thighs together.
“Mmm, I drank too much water earlier… Gotta go potty…” She said, crossing her legs and rubbing her crotch with her hand as she tried to suppress it a little more, before surrendering and climbing out of bed.
She hastily trotted into the bathroom and squinted as she flicked on the lights, pulling down her panties and sitting on the toilet.
“Oooh, shouldn’t drink a whole glass before falling back asleep.” She said as she felt a mixture of tingling between her legs and relief as she emptied her bladder.
Riko didn’t feel or notice your limp little form plummeting into the toilet bowl along with her stream of urine. You had suffocated inside the tight confines of Riko’s crotch sometime after she had fallen asleep, and now you were just a tiny bit of refuse ejected from her monstrous body. Without looking at the toilet bowl, she flushed and exited the bathroom.
She would remember about you later that day and look all over her person and around her room for where you had gone, but not a trace of you was to be found. Eventually she gave up, and just assumed you had run away or were a figment of her imagination.
