By Accidentally Slipping

Sarah yanked my shorts down, revealing my fully erect dick. Now, I was pretty proud of my cock. 8 full inches, and not a scrawny little stick either. I'd probably get some girls if it weren't for that bitch Raine spreading a rumor that my cock was a shrivelled twig with STDs. Only one with STDs was that fucking slut. Well not yet, anyway.

"Ooh...you're gonna stuff my wet little snatch with this nice big dick, Ward?" Sarah moaned sultrily as she adjusted unsteadily, fumbling to remove her shorts as she positioned herself above my rigid pole.

Then she slipped. And oh, what a glorious slip it was.

Her foot caught on a puddle on the bathroom floor and her body shifted forward slightly. Unknowingly, this caused her wet asshole to be the hole above my cock rather than her aforementioned wet pussy. It entered maybe 2 or 3 inches, causing her to wince but she managed to catch herself. She gripped my shoulders for support, biting her lip as she lifted herself inch by excruciating inch.

"Ohhh fuuuck, it's big! Mmmph!" But her efforts to lift herself prove futile as gravity takes over, impaling her completely in one sudden plunge. Sarah shrieks in ecstasy, the velvety walls of her virgin ass clenching tightly around my cock as a powerful orgasm rips through her quivering body.

"AAAHHH! OH MY GOD, YES!! IT'S SO DEEP! FILL ME UP!!"

Overcome with primal lust, Sarah begins bucking wildly, not even caring that she was being fucked in the wrong hole. She slammed her hips against mine with abandon and her huge tits bounced lewdly with each frantic thrust. "FUCK ME HARDER!! USE MY SLUTTY ASS!!! BREAK ME WITH THAT FAT COCK!!!"

Squeezing her fat tits firmly, I crushed my lips against hers in a passionate kiss, our tongues dancing lewdly. Sarah mewled into my mouth, her face contorting into a blissed-out ahegao as I railed her harder.

"Mmmmmmfff...haaaah...yesss...fuck me silly!!" Sarah moaned desperately between sloppy kisses. The bathroom echoed with the sounds of skin slapping and loud moaning.

"Aaahh...I can't...stop cumming!! Wreck my ass! Ruin meeee!!" With a final grunt, I buried myself to the hilt and unleashed a torrent of virile semen directly into Sarah's spasming asshole. She wailed in rapturous delirium, her entire body seizing up as a mind-shattering orgasm consumed her. "AAAAAHHHH YESSSS!!! BREED ME!!! FLOOD MY ASS WITH YOUR SEED!!!"

Utterly spent, Sarah slumped bonelessly in your arms, a blissed out expression frozen on her face as thick rivulets of girl-goo poured out around my still-twitching cock. Her eyes remained vacant and unfocused, tongue lolling obscenely.

I took advantage of her post-coital stupor to carry her body to her bed in the guest room, putting a towel under her body and putting her clothes next to her. Moments later, Sarah stirred groggily, shaking her head as clarity returned. She sat up slowly and touched her ass, still dripping with my and her cum.

"Nngh...fuck...that was insane..."

Wait. What happens after the horniness wears off? Does she still remember what happens? Am I about to get cooked for **** my cousin? But it's not **** if it's technically consensual right?
