Cassidy takes care of Rachel, you take care of mom

"Oi! Get back! I'm warnin' you!" Aunt Rachel says, quickly beginning to panic over your approaching brother. She reaches over and grabs the first thing within arm's reach, a butter knife, and brandishes it at him. She looks to the front door, already blocked off by her masturbating nephew, and considers retreating for now. Maybe come back with a gun, next time. They're legal here right? Just gotta find a gun vending machine or whatever.

"Heheee! I just wan..." *erk* "I jus wanna gib you a dose... Aunt... Rachel... don worry..." Cassidy stumbles out, possibly attempting to be reassuring, but his furious stroking and laser focus on her chest says otherwise. He doesn't even notice her attempt to stab him with the butter knife, the dull blade uselessly bouncing off his t-shirt, as he continues towards her, unabated.

"You two have fun, I'll go get mom!" You say, ignoring the sexual **** and failed **** of self defense and run off to make sure your mother isn't in a coma yet. You run up the stairs to your mother's room, formerly the bathroom, and hesitantly lift the toilet lid to check on her.

Luckily, your mother seems rather content eating her lunch; half a three day old pizza no one wanted any more, so you tossed it into her trough for her. The upstairs toilet now acts as mom's food bowl, since she now performs most of its duties full time for the house. She didn't even seem to question it when her dinner started being served in the toilet, but Cassidy had to spend three days teaching her to eat out of it without using her hands 'like a good pig'. Now she's content to eat whatever we throw in there, even licking it clean when she's done. She keeps the bathroom spotless with her tongue.

"Mmnum... num... oh hey, Marcus... num num... need to use the piggy?" Your mother asks you, turning her head towards you when she notices you opened the lid. She opens her mouth wide, showing a half chewed bite of pizza, and waits for one of her sons to piss in her face, which is the usual reason you would bother lifting the lid. If you were horny, you would have just fucked her cunt or ass while she continued to eat from the trough, but you have other business today.

"Not right now, mom, it's time for piggy's bath. Go on, git!" You say, smacking your mom's fat ass repeatedly until she begins to crawl towards the shower. She tends to get pretty filthy these days, being a toilet and all, so you have to bathe her regularly, but its been a few days since anyone bothered and she certainly doesn't notice or care. You help push her over the edge of the tub, lifting her jelly rolls and tossing her in with a loud thump. She hits her head on the faucet on the way down, but being piss drunk, as usual, the pain that would normally cause instead makes your mother nearly orgasm by itself. She quickly begins openly masturbating in the tub. You're never going to be able to hide that you turned her into a piss whore if she keeps acting like this.

You decide she needs a cold shower to calm down, so you twist the cold knob and start the shower, picking up the fancy moveable shower head and aiming it directly at her face, soaking her head with freezing water. Rather than hating it, she begins stroking herself harder, and she immediately tries to drink as much of it as she can, since that's what she's usually expected to do when one of her boys starts spraying her in the face with some liquid. You point the shower towards her cunt and you roll your eyes as she begins to orgasm repeatedly. You turn it on high and clean the many wasted loads out of her holes.

After lifting your mother's various rolls and cleaning the filth out of them, you decide she's probably clean enough to at least not be obviously the house toilet at first glance, so you turn off the water and your mother slows her masturbation, missing the pleasure of being tortured with cold water already. She looks up at you, putting on her cutest face.

"Can you give mommy a dose, Marcus? Piggy is thirsty..." She opens her mouth and obediently waits for her son to jam his cock in it. Cassidy taught her to beg this way when he began turning her into a proper piss whore, this probably means she's coming down a bit and needs more. You're not even sure if she believes any of this anymore, but she really does seem to enjoy it, so it hardly matters. She flutters her eyelashes at you with her mouth still agape and curls her tongue over her chin. "Pwease?"

You look down at her, weighing your options. On the one hand, her being **** in front of aunt Rachel would be fairly obvious, but on the other hand if she's coming down and begging like this in front of her sister it might also be pretty obvious. On the OTHER other hand, you do have to piss and it's not like you're gonna do it in mom's food bowl, like a barbarian, especially when she keeps it so clean, but on the other other OTHER hand, you did just clean off the pig as well.

You ponder your options over your naked shivering mother.
