Anal

"Alright girls, next I'm going to be using your assholes. Both of you bend over the coffe table while I grab the lube."

The twins do as you say and lie on the coffee table in the middle of the living room, pressing their tits against the glass as they lie there with their asses pointing out. You grab the lube which you've kept nearby and bring it over to the coffe table, popping it down next to them for easy access. You apply a generous amount to your cock before squirting some directly into Tracy's asshole as you'll be using her first. She lets out a soft gasp as you squirt the cold liquid onto her pretty pink asshole, before slowly sticking your cock into her. Tracy's ability to tolerate and even find pleasure in anal has risen greatly over the past couple weeks and so sticking your cock in is no issue. However, her rear hole is still very tight at first and you have to work slowly due to the resistance. Tracy is focusing on her breathing as you plunge your cock in and out of her ass. Slowly, knowing she can take it, you work your way up to a much faster pace, until eventually your pounding her ass doggystyle like there's no tomorrow. Tracy is jiggling back and forth on the table as you roughly cave in her back door. She's currently looking to the side, facing away from her sister.

"I want you to look into each other's eyes as I use your assholes."

Tracy turns her head so she's staring straight into her sister's eyes, the two are barely 30cm apart. Tracy continues to breathe heavily as you clap her ass cheeks, focusing on minimising the pain and maximising the pleasure by being as relaxed as she can.

You give her a hard smack on the ass. "Tell your sister what I'm doing to you. Tell her what she's in for."

Tracy continues staring into her sister's eyes and vocalises what she's feeling.

"Oh fuck! He's fucking my ass so hard. He's stretching me out so much, it feels so good and so painful at the same time. Fuck Mia, I can feel him rearranging my guts!"

Mia looks deep into her sister's eyes with a look of terror. Tracy had had her ass used dozens of times, by dozens of different men, but Mia on the other hand had only tried anal for the second time yesterday and was probably still sore from that rough ass fucking.

Satisfied with your use of Tracy's rear end, you pull your cock out of her and shift over to Mia. Tracy lets out a sigh of relief as you finally finish pounding her ass more roughly than you ever have before. You give Mia the same preparation and squirt some lube into her ass, there's no need to put any on your cock as there's still plenty from Tracy's ass as well as her ass juices. You push your cock head up against Mia's puckered back door but there's significantly more resistance than there was for Tracy's. You decide you should treat the two sluts equally and be just as rough with Mia as you were with Tracy . For this reason, you **** your cock into Mia's ass, sparing no time to warm her up and instead plunging balls deep immediately.

"Oh fuuuuck! Not so rough, please daddy!"

You slap her ass cheek hard. "I'll be just as rough with you as I was with your sister, it's only fair. If you can't take it then just use the safe word mercy, but know that you'll be forfeiting the round."

Mia gulps nervously but doesn't say another word. Taking this as a sign of approval, you start pumping in and out of her ass, working your way up to the same speed you were going at in Tracy. The two sisters are still looking deep into each other's eyes. It isn't long before you're going at full pace and Mia starts squealing out due to your rough fucking of her asshole.

"Oh fuuuu-uuuu-uuuuck! Oh my god! Please daddy!"

"If you want it to stop, you know what you have to say whore."

Mia doesn't say another word, instead biting down on her bottom lip to deal with your forceful pounding of her asshole. Tracy sees the look of determination in her eyes and realises if she wants to win she's going to have to do something.

"Pound her ass hard sir. Fuck her harder. Really give it to this whore!"

Tracy's words of encouragement fill you with energy and you proceed to fuck her ass with a whole new level of vigor.

"Mercy! Please sir! Mercy!"

You bring your rough **** of her asshole to a halt and pull your cock out of her ass. Tracy has a devillish grin on her face, knowing she's secured herself the round. Mia on the other hand has black, mascara filled tears running down her face as a result of you absolutely ruining her asshole. She grabs her ass cheeks and pulls them apart slightly, hoping this will relieve some of the pain.

She's now whispering to herself manically. "Oh fuck, fuck, fuck. So big. So hard. Feels. Raw. My ass. Fuck, my ass. Ruined. Fuck."

It appears you've broken this bitch. "Are you ok whore?"

She snaps out of whatever trance she's in and turns her eyes to you. "My ass. You fucked it so hard. I don't want to lose."

She gulps before speaking again. "Please daddy. Keep fucking my ass. I want to win the round. I'm sorry I used the safe word. I can take it this time."

"I'm sorry whore, but you already lost. And I think your asshole's already endured enough for now anyway."
