Anal with Big Butt Cousin

"Go ahead. Do it then." She jeered while slowly -- with swift steps that rippled and gyrated them -- pivoting around to reveal her humongous naked poopdumper to my view. Unconcerned that my eyes peered intensely into her holes -- specifically her fuckable anus -- while she continued.

"Fuck me." She urged while craning her neck to peer and grin at me with green appraising eyes -- including my glaring erection -- before giving another salacious sway of her posterior and subsequently releasing a series of tooting puffs from her anus, which pushed out the rectal pucker and increased my arousal, despite the odour now wafting in the air.

"Fuck your cousin in the butt."

"Or can't you even do that too?"

This was Rebecca. Our beautiful green-eyed bane of a cousin, generously endowed with a butt that somehow managed to rival -- if not closely match and resemble -- even our mothers'.

Despite being just eighteen years old, Rebecca had already developed -- even more now at eighteen -- an ass that completely commanded attention whenever she moved, or should I say walked to be more appropriate.

It progressed significantly -- alongside the brazen comments, nether bulge from her silhouette in the bath and the horrendous stank of her farts -- before we noticed to our amusement.

Despite being unremarkable with boobs; having relatively average pairs. Little Rebecca was blessed -- almost compensated -- with a butt twice what was usual for even girls her age.

School skirts no longer fit and were extremely tight when they managed to.

Mom and dad ordering her to wear looser clothing in the lower end to prevent indecency.

People making anal and butt jokes around her.

Her girlfriends squeezing and groping her buttcheeks.

And some just shamelessly staring in awe and confusion.

And for good reason too. It took impressive self-control and restrain not to ogle or look whenever Rebecca strode into the room, especially when you were provided with the godly view of behind - two twin globes of flesh mashing and grinding amid her anus while she moved with brazen, almost defiant confidence.

All of us dreamt of sodomizing her - in our own respective ways.

Straddling her to the wall by the wrists and listening to her whimpers of delight as our member violated her anus.

Grasping her by the scarlet hair and burying our dick all the way up to her colon.

Roughly pistoning into her butt up until her sphincter quivers and constricts along our buried length, causing us to balm her abused rectum with our semen and urine.

Her conduct didn't help that desire either.

She wore tight spandex daily, despite our parents' disapproval.

Wore buttplugs.

Frequently farted in our proximity to bring attention to that accursed rear.

And allowed us brief touches when we were good boys.

The only thing she didn't allow were fingering and fucking her ass.

Swatting away any palm that tried to do so.

Moving her butt away when an ambitious finger pressed at her pucker.

And giving a resounding slap on the cheek to anyone who managed -- either through tact or skill -- to shove an entire finger all the way in, which happened fairly frequently considering her leniency.

Here was that same girl asking me to sodomize her.

Sodomize her big fat ass.

"Or are you not into Anal?" She inquired while wriggling her giant butt at me again.

"I can get someone to do it if-" She began before trailing off to silence when I moved.

Sauntered forward, I grasped and lifted my huge dick up -- giving it a few pumps -- before pressing the leaking head against her rectal bud and clasping her wide hips to hold her in place.

Slowly and slowly..... inch by inch I admitted myself in, pushing my dick into her anus up until my crotch flattened her giant buttocks and I lodged deeply in her burning rectum.

She gave a twitch of it then and sent me to the edge, causing me to regrettably -- despite my best protests -- shoot out multiple strings of semen into her bowels.

She continued the pressure, squeezing and draining more of my semen into her bowels while rocking -- with my dick embedded deeply -- in surprise.

"You came already!?"

"You are pathetic."

"That's why I never let you fuck my ass."

My memory was fuzzy, just revelling in my dick furiously unloading the entirety of my pent-up load in her buttocks, which she intensified with multiple squeezes of her sphincters.

The snap happened in the haze too and urine immediately join in after the cum, piss shooting out of my dick to pool and churn the semen in her rectum.
