Fuck this asshole's assholes

"Shut the fuck up and spread your ass" you growl. She whimpers and reaches back to spread her assholes for you. You spit on both of them, line up your cocks, and begin slowly shoving them into her tight holes.

She plants her face down into a pillow and groans in discomfort as your **** your way into both her assholes. Both of your dicks can feel the other one through the thin dividing membrane, multiplying the stimulation of each thrust and increasing the tightness even more.

"I promised you that you would still be able to use your holes for sex..." You begin explaining to her what she's in for, punctuating each sentence with a few long forceful thrusts. "I wasn't lying... Not only can you them for sex... you have to use them for sex..."

She looks back at you in horror and you answer with another volley of thrusts. Goddamn. Its a very intense feeling to be both dicks in a DP. You had tried fucking a woman with a butt plug in her ass before, and it had created a pleasant sensation, rubbing against your dick through the vaginal wall. But this was on a whole other level. You're almost having trouble focusing on explaining her fate to her. Oh well, you're not sure she's even listening to you. She probably has two other things on her mind, and in her ass.

"You see, I own your Tinder profile and I own what you use it for. You are to upload the pictures I've taken today, and editing your description to let men everywhere know that you're a nympho slut who just wants to take as many dicks possible up her tight ass. You are to meet up any man who uses a Super Likes on you, and let him have his way with your ass. Do you know how much a Super Like costs? $1. That's the price for any man to fuck you now. And you don't even keep the money. You're just a cheap whore, being pimped out by a corporation for pocket change."

And with that, you begin your full doubled barreled **** on this poor woman's ass. She lets out a long continuous wail, the pitch fluctuating with every thrust, and you hook your right arm around her neck with your elbow under her chin and squeeze, pulling her head back and up. You reach around with your left hand and use it to cover her mouth to muffle her cries as your relentlessly pummel into her. But despite your rough treatment, she doesn't try to resist. She knows you own her holes, and have every right to fuck them as hard as you want.

You begin to notice a hint of sexual satisfaction in her moans and notice that she has managed to get her arms under her and began rubbing her nipples, attempting to eek out an orgasm from that and whatever fantasy she can spin this to in her head. You remember she told you once that she was sometimes able to orgasm from nipple stimulation alone. Better put a stop to that. "Are you trying to orgasm by rubbing your nipples while I fuck your ass you pathetic nympho? Don't you know that your nipples don't have any nerve endings?" You aren't sure at first if it worked as she keeps rubbing them, but she soon gives up and begins sobbing in frustration. Her main vice in life now tantalizing close, but forever inaccessible. Unless she really learns to love anal.

"You asshole, what did I ever do to you?" she manages to get out between sobs and your continued thrusts into her.

"I'm not going to dignify that with an answer."

With that you begin your final onslaught of her ass. You cum deep inside, first one cock then the other shortly after. You pull out and give her a hard spank on the ass.
"Hey! You own my holes not my body. Don't hit me!"

"Fine, whatever. Just spread your holes so I can take a profile picture for you"

You begin writing up her profile:

"I'm desperately horny, but I have a rare condition that caused me to grow a second asshole instead of a vagina (Its not connected to anything, so its always perfectly clean). I'm looking for a man with a big dick to come fuck my assholes in the hopes that if you stretch me out enough, I'll be able to orgasm. So if you've got a big dick, send a super like to this super slut and help a girl out.

Being an experienced Dom is a plus, I want to be fucked hard and verbally degraded. I have a bit of a CNC fetish, so do what you want. I'll try to stay in character, but just in case, my safeword is 'adultery'.

PS, bring a friend. I think being double stuffed might help."

While typing it out, you hear her musing to herself that at least now she doesn't need to worry about taking birth control. You decide to add another note.

"PPS, since I can't get pregnant anyway, I want you to fuck me raw"

"Alright slut, I'm going to head out. I'll be back to check on your progress later. And remember, I own your Tinder profile. You are to use it to find men to come over and fuck your ass, but you aren't allowed to edit or even look at your description or pictures. If men ask for nudes or other proof that you're real, comply with their demands. Additionally, I have conditional ownership over you body. Whenever I am using your holes, I own your body as well. I have chosen to extend this privilege to any man fucking you. You'll do whatever sexual thing they ask of you during your encounters."

She collapses back onto her couch as you leave. After you're out of earshot, you add the final, secret, twist to her punishment. "Her new asshole is connected to her womb, and she is capable of getting pregnant via it."

That should be a big surprise for her later.
