Tonya Mousekewitz In; Alone In The House.

Momma and poppa went off to buy some cheese and fruits/berries and seed. They would be at the market a good portion of the afternoon. They took Fievel with, to drop him off at Tony’s place.
Poppa, not momma, knew about what Tony and Fievel sometimes did with each other. The reason for this, is he once walked in on them, in Fievel’s room.
Instead of punishing Tony, or in a way punishing, he’d not said anything. Of course, after fucking Tony, then allowing his son to suck him off at another time, telling her was a bad idea.
So Poppa pretty much kept his mouth shut about it.
This left Tonya home alone, to do laundry, as usual.
At first, she just sat in the main room, doing some of Fievel’s wash. As she got up, hanging Fievel’s many red shirts to dry, along with his many underwear briefs, which you usually don’t see.
Some of them, having brown marks in them, from Fievel’s crazy fetish of pooping. And of course also, his navy blue pants.
As she sat for a few moments, sewing a hole in Fievel’s one shirt… which for some reason, he kept ripping remarkably at the same spot, on a lot of his shirts. 
She began imagining Fievel fucking her vagina. Even though he was her brother, she wanted sex with him all the same.
She rubbed her right paw against her genitals, as she made her way to Fievel’s room. His bed was still damp from last nights bedwetting, and she was to change his bedding, and clean those too. Instead of just ripping off all of Fievel’s covers, and grabbing his blanky, she sat on Fievel’s bed.
She grabbed up blanky for a moment, then placed it to her nose.
She took a deep breath in, smelling Fievel’s odors on his blanky.
My brother’s smell gets me sooo aroused. she thought to herself, as she quivered with a slight orgasm, from just her brother’s scent.
She dropped it on the bed, nearest to his pillow. 
She pressed a paw into her mouse body, and pretended it was her brother Fievel. Then she lifted her dress, and ventured in with her left paw. “I don’t know what’s wrong with me, but I sooo much want my brother doing this to me. “
She fiddled with her vagina, as she turned herself on even further.
She soon stuck a finger up there, then another soon after.
She knew it wasn’t gonna harm her, and she’d already broke that skin, about the first time she’d ever masturbated.
She knew it was nearly impossible to get Fievel to do this to her, cus as she masturbated, Fievel was getting fucked over at Tony’s house. His wife had left him, having caught Fievel giving Tony a blow job.
“Huh! What was that!?”
Tonya thought she heard something, as she stopped for only a moment. Sitting Indian style on Fievel’s bed, so that she could smell last nights bedwetting.
Oh gawd Tonya, you’re not actually gonna, on,, on Fievel’s bed? thought Tonya to herself, as she let out a squirt of piss.
“Ohh gosh, I so much know I shouldn’t be doing this, but I like it soo much.”
Tonya pressed out a little more piss, as she kept her fingers of her left paw in her vagina. The feel was so arousing, that her vagina became juicy besides, as she pressed her entire paw up there.
She pressed a little harder, suddenly feeling pain in her anus.
“Ohh gawds, I’m just gonna, Fievel sometimes does it.”
She pressed a little more, feeling the unmistakable pain of her poop pressing against Fievel’s damp bedding.
Oh Tonya, get a grip, I could end up in so much trouble. she thought to herself, as she pressed.
The feel reminded her of how Fievel’s cock might feel in her, and she became wetter down there, with piss, then some more vaginal fluid. As she thought to herself, she knew, this wasn’t something she should be doing. “Oh god Fievel bro, you up me feels so good.” she had her eyes closed, as she pooped out a clump onto Fievel’s bedding, she kept imagining it was her brother’s penis up her, rather then her pooping. She pressed out more, as she peed more as well, all the while, imagining it was her brother buttfucking her instead. Her vaginal fluids and piss were coming out off and on, not at once, but pissing, then cuming.
Being so naughty, felt so good, she couldn’t seem to get enough of it. She pressed even harder, ridding her body of all the poop, she had to poop. She pressed so hard, she lost anal fluids onto her poop mess. “Ohh gawds, I,, I’m really gonna cum.”
Suddenly as she whimpered and groaned hard, she lost nearly a pint worth of vaginal fluid. Her peaked orgasm, and this let her suddenly tired, as she laid back for a few minutes.
She laid there, catching her breath, thinking to herself. I love you brother,, thanks so so much Fievel. She thought it about three times, as she had a tear go down her left cheek, wishing he’d do it to her for real.
She laid there for around five or ten minutes, before getting up, then folding Fievel’s bedding up. She carefully set Fievel’s blanky aside, as she carried his bedding to someplace she could dump her poop off of them. She soon made clean water, and started doing Fievel’s bedding. 
She shook the whole way, in fear someone might catch her.
Her nerves calmed, almost as soon as Fievel’s things were soaking for a little while. This meant, that no one would know for sure, now. His bedding was clean enough, that only the stains left by Fievel, should be visible anymore.
She went to the dinner table, and rested her head on her right paw.

Even if it is incest, I really wish I could get fuck by Fievel himself.

She started daydreaming, as she would soon finish working on Fievel’s wash.

END!!!!
Really? Hehe, cant be sure.
