Tanya had one last look around, just to be sure she was alone. And then she went into Fievel, her brother’s room. She took off her dress and skirt, and then looked through her brother’s drawers. She found underwear which were thicker then usual. They weren’t made to soak in the whole bladder. She assumed, they were made extra soft, just for comfort. She tried them on. The button fly actually worked, as she placed her right paw into it. She let it close again, as she now felt both paws over that are of the underwear. She rubbed her paws against both sides of her slit, as he rubbed at it with thumbs, only mice like these even had. She let out a whimpering moan, as this turned her on some. She loved placing on her brother’s clothes for some reason. “Oh Tanya, why do you do this?” she said aloud, as she rubbed her paws, down under her vagina. At this point, she was in the middle of Fievel’s bed. She groaned, as she rubbed her paws back up, and across her slit. And then, pressing down on the top of her vagina, she pressed to pee some. She was leaking too, as she seemed to not care. She was suppose to clean Fievel’s covers anyways. She wasn’t leaking menstrual fluids, but she was still leaking some sort of fluid. She enjoyed it, as she peed a little. Pissing a pair of her brother’s underwear, turned her on, as she rubbed at her slit, through the underwear. She groaned and panted, as she peed a little more. Her bladder hurt, as she caused the underwear to leak her piss at the bottom. As Tanya toyed with her slit through her brother’s underwear, her anus hurt her. She also had to poop, as she allowed more of her bladder out, pissing onto also Fievel’s bed. She opened her right paw fully, and then rubbed it against her vagina, on the outside of Fievel’s underpants. She groaned and panted, as she pressed allowing some of her poop to slide from her body. She grunted and groaned, as it hit her brother’s underwear. She felt her left paw down to it, and then gave the outside of the underwear a squeeze. She enjoyed feeling her mess through her brother’s underwear, as she pressed to push out another piece, as she pooped a larger piece then intended. She filled Fievel’s underwear fully, as she opened her left paw, and then pressed it against her ass. She peed some, as she enjoyed her mess pressed up against her. She collapsed on the bed, mashing the poop into her further, and also causing it to leak from the sides of Fievel’s underwear. She moved her right paw to the underwear’s right leg, and then pressed it in. she took her fingers, and then pulled on the side of her slit. She pulled very hard, causing her hole to expand against the underwear. She caused herself to squeal, as she brought her other paw to Fievel’s underwear next. She put in next to the other-side of her vagina, right at her opened slit. She placed her index finger in it, and then rubbed it up and down. She soon stood up, and then stripped Fievel’s underwear off of herself, poop everywhere. She wiped herself clean on Fievel’s covers, as she moved to the floor. At least for Tanya, Fievel’s covers were spotted with brown spots from Fievel doing this exact some thing. One of the reasons she let herself do it. She collapsed on Fievel’s floor, tucking her legs up, and then while on her knees, she replaced her right paw to the side of her slit, and then pressed in hard. She pulled a bit, causing her hole to be further exposed. She then took her left paw, and then took three fingers across the bare skin of her vagina. She groaned, as she peed some onto Fievel’s floor. She rubbed at herself up and down, moaning quite a bit, as she turned on her vagina. Tanya pressed her left paw fingers further, panting and groaning… she caused herself to squeal again. Squeaking like the mouse she is, her fluids started flowing some, as she caused herself both pain and pleasure at once. She pressed herself even further, and then fully pawed herself. She stuck her entire paw into her vagina, and then pissed on it some… as she felt as though she would soon cum all over it. Tanya pressed trying to poop just one last piece, not knowing she even had to go at all. She pooped a long piece, right at her feet, as she was sitting on them. She squealed again, as she pissed on her left paw. She moved her paw in and out of herself, turning herself on.
“Oh Tanya, that’s it, make yourself cum.”

She said aloud, as she was panting as if she’d already cum. She peed a little more, as she moaned heavily. Orgasm pulsing through her body, she moved her paw in and out of herself.
“I, I am gonna cum.”
She said aloud, as her body released a huge load of silky white fluid, almost like a male’s body does. She panted for a breath, as she looked about the room. She had a mess to clean up, as she got herself started with that. She wasted little to no time to start, as she first through away the larger clumps of her poop. She folded the blankets, and then worked on cleaning them too. After all the covers and Fievel’s underwear were in the drier, she placed on some of her best clothes. And then took them off. Giggling some, she dressed in her brother’s favorite outfit. Her timing was great, as she met Tony at the front door.
“So are you ready to watch some movies Tanya?”
Asked Tony, as he gave her a funny look.
“Am, I just like wearing my brother’s clothing when no one is around.”

“Oh. Well I like you in them. So are we watching a movie?”
Asked Tony.
“Well of course we are.”
 Tanya smiled, as she invited Tony in.
“So where’s Fievel?”
Asked Tony.
“He’s somewhere with Denny.”
Said Tanya.
“Can we do something before they come back?”

“I can’t say Tony, as they’re suppose to be back… well now.”
Said Tanya.
“So they’re alone together?”

“No. after last night, they’re not allowed to be alone together for awhile.”
Said Tanya. It wasn’t long after she said it, that Mama, Fievel and Denny were back from the Cheese store.

(FIN!)
