Making Sarah his personal slut

Sarah's room was just another average girlish room, pink wallpapers adorned the walls, she had a large bed, a bedside lamp on a wooden cabinet, a wardrobe to the side, with a few pictures on the walls.

The sight of seeing a big, hulking man with a cum covered woman would really strike as odd in this room.

Adam barged into the room, almost blowing the door off it's hinges due to his new increased strength. Sarah was draped over her shoulder, a little bit exhausted from her previous orgasms in the shower, still covered in sticky, pearl-white sperm.

Adam left the door slightly ajar behind him, and dumped his little sister onto the bed. She backed away a little as Adam hastily jumped on too and lined up his 16.5 inch monster with Sarah's small, pink pussy, copious amount of pre-cum still flowing from his seemingly limitless reserves.

"It's time for you to get fucked by a REAL cock, Sarah. You can forget your wimpy, limp-dicked boyfriend now." Adam says while slowly sliding his cock up and down against his sister's opening, lathering it up with more pre.

Her boyfriend was not exactly small in dimensions, he would have probably been way bigger than the previous Adam in the genitalia department, but now his penis would not hold a candle to Adam's new and massively improved pussy destroyer. Sarah's pussy juices were flowing like a waterfall around his colossal meat, and she was mewling softly.

"Adam-Please b-be gentle, okay? I don't think I c-can take your cock. It's too big! You'll break me!"

"Nonsense, sis! Your flexible little cheerleader body should be able to take it, no problem. I won't hold back!"

With that Adam started pushing his big mushroom cockhead between Sarah's nether lips. She gasped loudly, her eyes fixated on the monstrous phallus slowly entering her honeypot, it sure hurt but it was easily overshadowed by the electric pleasure running up her back. As soon as the head plopped into her pussy with a resounding pop, she came hard around the intruder in her pussy and didn't stop cumming as Adam continued to push more and more of his steel-like monster dick into his sister's tight cunny, letting out deep guttural moans.

Sarah tightly grabbed onto her brother's big muscular back. Her orgasm was nowhere near stopping and she was moaning and squealing uncontrollably as she clung onto her big brother as if he was her final hope on the planet, he was the source of the pleasure, he was the source of comfort. She almost bit into his shoulder trying to stifle her moans, Adam didn't mind and proceeded to bury more of his unbending, throbbing shaft into his blonde sister's cunt.

He stopped for a moment and looked down at her stomach, his thick shaft was bulging through her skin, stretched taut around the gargantuan fuck rod. Adam could almost see the veins on his cock throbbing through Sarah's bulging tummy, and unloaded another blast of pre-cum in response to this almost, impossible sight.

Sarah's face was flushed red, tears streaming down her face, she almost felt like she would go insane from pure pleasure due to her perpetual orgasm. She suddenly grabbed her big brother's head, and pulled him into a deep kiss, mashing their lips and tongues together.

Adam eagerly accepted and stopped moving to savour their, deep passionate kiss, tasting his sister's sweetness and relishing in her taste.

They didn't know how long they kept kissing but Sarah seemed to have calmed down a bit now, albeit a little out of breath.

"Huh-huh-huh... Adam, please! Fuck me! Harder! I want you! PLEASE!" Sarah almost screamed out.

Adam pulled back a few inches and slammed back in with more ****, almost burying half of his cock into her cunt and slamming against her cervix.

"YESSSSS! FUCKING GAAAWWWD!" Sarah screamed in bliss, "TEAR ME APART, BRO! DESTROY MY PUSSY WITH YOUR BIG FUCKING, BEAUTIFUL COCK!"

Adam could feel that something had snapped inside of her little sister, but he didn't care, he was gonna give her what she wanted, a hard fucking she would never ever forget.

"YOU WANT THIS FUCKING COCK! I'LL GIVE IT TO YOU, ALL OF IT! FUCKING TAKE IT YOU SLUT!" Adam yelled as he too felt himself lose control and pulled back almost completely before slamming back in with almost all of his new strength. The bed creaked loudly under his ****. His cock busted through Sarah's cervix and struck hard against her womb, all 16.5 inches of thick monster meat bulged obscenely through Sarah's stretched belly.

She howled as another mind-shattering orgasm hit her, and strangely there was no pain now even though it would have been physically impossible to take something that big in your pussy. And honestly, Sarah didn't care and neither did Adam who felt her sister's already tight pussy clenching even harder on his massive fuckpole and felt his balls rumble in their sack as another huge load travelled up his bucking and throbbing cock to be unloaded into his sister's pussy.
