Rough!

You decide that you've waited long enough! This ass belongs to you, and that means you get to fuck it however you want! With an evil grin, you grasp Sakura's hips tighter and rear back.

"Sorry, but no." you plunge straight in!

"W-Wait, Johnny-kun slow do-OH FUCK!" whatever the pinkette was saying was cut off by the sudden feeling of absolute fullness in her rear end.

You grit your teeth. Sakura's anal passage was infernally tight! But it was a good kind of tight, and combined with the warmth along with the wetness on your cock created an almost indescribable feeling. You had to stop a moment just to get used to the feeling. Sakura meanwhile was groaning and shuddering as she herself also struggled to brace herself.

"How does it feel?" you ask with a grunt. You were ready to start thrusting, but she was so tightly clenching around your dick that you could barely move!

No response.

"Sakura?"

Again, no response. You frown a bit, and another evil idea crosses your mind. Smirking, you raise your right hand.

*SMACK!*

Sakura shrieked, and you felt her clench around your manhood even more. Your palm came down as hard as you could muster, leaving a bright red handprint on her right buttcheek. You watched in mild amusement as her vagina starts to gush with female ejaculate.

"I asked you a question." you say nonchalantly.

"I-IT FEELS AMAZING~!" Sakura finally responded, turning back to look at you. She had this grinning, slutty expression on her face that wouldn't be out of place in a hentai manga.

"Good girl. Now could you try to loosen up a bit so I can keep going?" you ask.

She nods, "O-Okay, just give me a moment."

It took a few seconds, but you felt her butt finally loosen up enough that you could start hammering away at it. You started slow, sawing in and out of her asshole. Sakura started moaning, letting out little 'oh yes's and 'keep going's. Once you felt that she had started to adjust to this speed, you picked up the pace, going a little faster. That only caused her exclamations of pleasure to increase in volume and frequency.

After a few minutes you were just pounding away at her asshole with reckless abandon, and Sakura was screaming her enjoyment at the top of her lungs.

"Fuck, Sakura. Y-You little slut. Tell me how much you love getting fucked up the ass!" you grunt, going for the dirty talk.

"I LOVE IT SO MUCH, JOHNNY-KUN! KAMI, YES! KEEP FUCKING ME! FUCK MY ASS FOREVER!" she shrieks, struggling to hold herself up on her arms at this point.

That just gets you even harder. You start groaning yourself, and lean over to whisper in her ear.

"Now tell me how much bigger I am than Sasuke. I'm sure you've seen his dick before, even if he never actually gave it to you."

Sakura shudders again before replying, "S-SASUKE-KUN'S DICK IS TINY COMPARED TO YOURS! HE'S AVERAGE BUT ONLY A BIG COCK LIKE YOURS CAN SATISFY ME!"

That sends you over the age. Letting out a loud moan of your own, you lean back and blast your new robo-slut's insides with your cum, filling her up to the brim. Sakura screams again, cumming once more as her arms finally give out from the pleasure.

You pop your dick out of her ass, and sit back on the floor to breathe. Meanwhile Sakura looks almost catatonic, your semen gushing out of her butthole like a fountain as she lays there.
