Very rough

It is amazing how quickly you descended into being the sadistic monster of your wildest fantasies. The only thing you want now is to enjoy your helpless sister and you want to do it in the most brutal way possible.

You grab her short from behind, turn her head sideways and push her right cheek into the wall while giving a hungry and rough kiss into another. Then you move your lips to her ear and whisper "It will hurt, cunt"

You don't make her wait for the fulfillment of your promise for too long. Your dick becomes an unwelcome guest in her pussy for the second and while the angle is very different, the power with which you rush inside is very similar. You quickly do several quick pushes while keeping Emily's face pushed into the wall. Then you slow down and start move in a slow rhythm but making sure that every inch of your pulsating manhood goes inside.

At the same time, your other hand, one that is free from holding Emily's in place, roams all over her back enjoying how tense her muscles are. And your lips keep kissing your sister's face, neck, and shoulder but those kisses have nothing gentle in them.

She silently moans and even through the gag, just from the tone of her voice, you can hear that she is begging for mercy. Almost instantly you let her understand that you'll offer no such thing and bite the smooth skin of her scapula while accelerating your hip movements.

Even this is not enough for you. A cruel idea comes into your twisted mind and you pull out from the warm embrace of Emily's body and even take your hands back giving her an illusion that you may be satisfied.

But, even if she had any false hopes, you destroy them slamming Emily back into the war, smiling imagining how her tits are squashed between her own body and the cold white surface. By doing so you **** her to lift her ass upwards a bit and immediately use the opportunity to enter into her ass. Even through the gag, her scream of pain is very loud, you can even say pleasantly deafening. And it is it, not a new wonderful feeling of ravaging tense ass, but an audial indication of her agony pushes you over the edge and you come in her ass even before you start fucking it properly.

When your extremely intense post-orgasmic bliss fades out you find that your sister has fainted and didn't fall only because you are still pushing her into the wall. Even that doesn't wake-up a caring brother in you. No, you just pick up her limp frame and casually drop her on a nearby sofa.

Before she comes back into your senses you hear familiar steps and the sound of the door opening. Carrie has come home. "Damn. You did screw her really hard!" She exclaims as soon as she sees the ravaged **** body. "You know, I...
