Frank goes all-out.

“Moo?” Nancy asked, looking around in utter confusion at her family. She began to half-heartedly wonder if maybe she was the crazy one for thinking something was wrong with the incestous scene happening beside her.

As the twins now paid no mind to what their mother was going to say from now on, their gentle touch became careless and rough, sending Tammy into another fit of moaning and twitching hysterics, only this time her hands actually slid down under the front of her drenched bikini-bottoms and began to shamelessly stimulate her pussy for anyone around to see. While they did this, their speedos began to stretch and tighten as the widening heads of their expanding genitals pushed out and downward against their spandex swimwear. The twins’ cocks were simultaneously growing in both girth and length exponentially, as well as dramatically darkening in color while the rest of their bodies’ skin tone remained white and slightly tanned.

The flared tips of their two-foot-long and solid-black horsecocks pulsed with need against the very stretchy material, and the boy’s happily horny expressions shifted into ones that held more raw lust than anything else. Without any vocal prompt from Hank, the testosterone-fueled and hormone-riddled teens pulled their cocks free from their speedos by ripping them right off of their midsections. Marcus and Danny each used one hand to guide their cocks towards Tammy’s tits and mouth. The pushed his flared cockhead against his aunt’s moaning mouth as his other hand grabbed a fistful of hair to keep her head in place, and to both of their surprise, the bimbo blonde’s mouth and jaw seemed to open and stretch wider than what should’ve been possible after the young man applied enough ****, allowing his massive cock to push further past her lips and down into her throat, which caused her throat to bulge considerably with an outline of his literal horsecock. Marcus, on the other hand, was determined to have Tammy’s plastic melons all to himself, grabbing the sides of her expansive tits and pushing them together before sliding his cock up underneath them, then let out a primal groan as he began to tittyfuck his aunt with reckless abandon.

Tammy simply moaned and squealed to the best of her very limited abilities as her sensitive tits were assaulted with pleasure while her face and throat and chest were being used like she were nothing but their personal fucktoy.

“Moo!” Nancy pleaded, trying to grab the twin closest to her only to get pushed her arm away. “M-Moo…”

“Calm down, Nancy, and stay calm this time.” Frank firmly commanded. “Like I said earlier, you just have to try hard enough if you want to throat a dick like mine, or your sons. Tammy’s fine, just look at her.” He extended an arm outwards to his wife, pointing at the slight smile on her stretchy lips as they repeatedly became very familiar with the base of Danny’s crotch.

“Yeah, Aunt Nancy.” Samantha said, kicking one foot up on the table and leaning back in her seat as she casually stroked her eight-inch cock. “Everyone’s enjoying themselves, why can’t you?”

Nancy turned to look at her in surprise, but then tilted her head and frowned at the sight of her perverted niece. Of all people, of course she’d be into this twisted situation, Nancy thought to herself. Why Samantha’s father decided to let her undergo a highly-experimental but ultimately seamless genital-swap surgery on her eighteenth-birthday was beyond her.

The new male hormones that the young raven-haired woman obtained had sent her into a sexual frenzy ever since. Samantha either masturbated or tried to fuck something with a pulse whenever or wherever the need (want) to do so arose; her libido was so high that her Nancy had never seen the ghostly-pale girl without some kind of obscene bulge from her permanent erection in whatever skimpy latex clothes she wore; she was covered in very fresh-looking and solid black tribal tattoos from neck-to-toe; her nails were painted with the same permanent and abyssal black color of her very full lips; not to mention she had a nose-ring, two piercings beside one another on her matte-black bottom lip, chain-linked nipple-rings between her perfectly round but completely natural double-D breasts, three needle-thin bars going through each of her small ears, a short tongue-ring, and another small ring pierced through the twitching rubber-black head of her very pale dick, every piece of metal studded with shiny silver balls at the ends. Samantha’s bikini was in tatters on the floor between them, and currently she was mindlessly and wildly pumping away at her big leaky dick with one hand while pinching her rubber-black nipples with the other.

“Moo, moo.” Nancy said condescendingly, having forgotten why she was so upset to begin with. Her sex-crazed family always did things like this whenever she tried to host a get-together, so it should’ve have come as no surprise when all of this started to escalate.

“Whatever, cow.” Samantha stated in her unkind but sultry-sweet voice, then took a drag off of the lit cigarette that was loosely dangling from her lips as she continued to stroke and fondle herself. “Why don’t you make yourself useful and blow me already.”

Nancy gave her gothic-punk niece a frustrated look, and then the seven-foot-tall milk-factory sighed as she slowly stood up from her creaking chair.

The middle-aged mother’s fiery and curly red hair bobbed around her pretty freckled face upon rising, and her watermelon-sized breasts jiggled and sloshed around with each slight movement that the large-bellied woman made, lightly spraying anything that was in front of her with the milk constantly misting from her wide and puffy areolas. Nancy had the curviest body in the kitchen by far, but most of her soft and plush flesh looked tight and firm without any of its old cellulite and love-handles, and she would’ve had a perfectly hourglass figure if not for the bulge in her stomach that resembled the belly of a woman who was nine-months pregnant with a set of triplets. The two spiky bovine-horns poking out from between the full ginger locks on top of her head shined in the kitchen’s light as she moved her chair away and got down onto all fours in front of Samantha, and the goth herself turned in her chair to face the curvy woman with a slight smile across her painted black lips.

Nancy didn’t return the smile, but she did lean forward and open her own full lips as Samantha grabbed her by one of her two long horns and pointed her cock towards the suggestive cow’s ever-willing mouth.

Just like with herself and her mother, all it took for Nancy to take more than half of Samantha’s favorite toy was a little push. And push she did, or, pull, technically. Without mercy, Samantha shoved Nancy’s face completely down onto her cock, the amazonian MILF’s large leaking nipples brushed back and forth across the cold tile floor as her niece began to treat her heavily-freckled face and throat like a fleshlight, her large belly and big ass wobbling and jiggling respecively as well. It almost surprised her when she felt a large and very strong pair of hands sink their fingers into each of her massive heart-shaped butt-cheeks, but being that she saw her horndog brother-in-law walk behind his daughter to get behind Nancy herself, she had a good idea of what was coming next.

“Ohh shit, mom.” Down on his knees behind her, Frank groaned, groping his former mother’s big, bubbly, bouncy, and very round butt as his hard foot-long cock was hot-dogging itself back and forth between the deep crevice of Nancy’s insanely plush cheeks. “I was going to fatten this thing up even more while I was busy turning you into the perfect breeding machine, but it looks like all your perfect ass needed was a little perking-up… By the way, everyone forget what I just said.” He chuckled, not sure if anyone, especially the tro behind him, was even listening.

Frank glanced over his shoulder just in time to watch Danny step to the table and clear half of it by carelessly pushing the dishes and food onto the floor. Tammy was then picked up like a princess by Marcus and laid down on her back along the somewhat narrow width of the eight-seater table, the deeply fake-tanned blonde’s legs sticking straight up in the air with her large, wide, and very fake butt hanging off of the edge while her head hung off of the other side. Marcus then proceeded to throw the back of her knees over his shoulders as he lined up his needy horsecock with her pussy and plunged it inside, causing screams of mind-breaking ecstasy to pour out from her bee-stung-swollen and permanently O-shaped lips while instinctively bringing her small hands up to squeeze her giant fake tits. Her wails of otherworldly pleasure were quickly muffled when Danny stuffed his own giant cock down the MILF’s wide-open and extra-sensitive mouth, and then placed his hands over her own on her wobbling fuck-bags, the strength of his own grip adding to Tammy’s own. The muscular twins then proceeded to fuck their aunt’s elastic and indestructible bimbo body with everything they had, grunting and moaning and panting like wild animals all the while.

Samantha had taken to grabbing the bovine by the horns, literally. Her ghostly-pale hands were wrapped around Nancy’s horns and were practically slamming the annoyed-looking woman’s freckled face repeatedly into her hairless crotch. Her grit teeth clenched tighter against the lit cigarette between them as she sadistically smiled and stared into her aunt’s sparkling blue eyes all the while, who was well-known in the family for contently doing literally anything that she was told to do by some strange and unknown compulsion she was cursed with.

Frank pulled back and angled his cock against Nancy’s sopping wet cunt as his other hand grabbed at her smooth rounded hip, and when he pushed his thick cockhead inside of her, all three of them let out moans of their own. By the time Frank had bottomed out, Samantha had begun to prematurely cum down Nancy’s throat from the vibrations being caused by her very muffled squeals. Frank couldn’t believe how tight and hot his newly-perceived sister-in-law’s cunt was around his huge cock, Nancy couldn’t believe how much cock was actually able to fit inside of her from both ends while at the same time in rapture for just how good it felt to be used like that, and Samantha couldn’t believe she hadn’t been fucking her aunt’s face on the regular if it’d been this easy to do this entire time.

Frank began to eagerly pump away at Nancy’s big and heavily-freckled ass as her perfectly-round ocean of jiggle-meat sloshed with each of the man’s powerful thrusts into it, and Samantha was shivering as she pulled her still-erect member from her aunt’s plump lips and ever-‘mooing’ mouth.

After that, the young lady slowly stood up and walked around to where her father was on his knees and fucking Nancy on all-fours as she reflexively pushed back into the man’s own thrusts in a perfect and powerful rhythm.

With a wicked snicker, Samantha quickly turned her wide hips to slap Frank in the face with her beefy dick.

“Ey!” Frank said, flinched, and laughed, all at the same time, but the pace of his hips never once stopped moving in perfect rhythm with the extra-tall Nancy’s much wider set. “What’s up?”

“Nothin’.” Samantha shrugged, then expressionlessly took the near-finished but still lit cigarette and threw it back into her open mouth. She chewed twice, then swallowed it, completely unfazed. “Wanna’ suck my dick?” She asked him, pushing her round hips, thick thighs, and drooling pierced cock out towards his face as the bottom-heavy goth’s hands reached up and began fondling her own chain-linked double-D breasts.

“Why are you even asking me?”

“Good point.” She giggled, then took a small step forward, allowing her throbbing cock to slide directly into Frank’s open mouth. Samantha’s knees shook and she bit down on her lip as her dad’s warm mouth casually engulfed her big dick in one go, pulling on and off of most of its length in a consistent rhythm as the rest of his tall and fit body robotically continued fucking the cursing, screaming, and subby wails of pleasure pouring from Nancy’s fuckable face.

His sturdy waist repeatedly bounced off of Nancy’s huge bouncy butt and Samantha was soon starting to pick up her pace in thrusting into her father’s mouth and bulging throat.

After Frank had set his sexual skill and reflexes to maximum and added a new password lock for both his phone and Master PC profile respectively, he’d joined in on the fun everyone was having.

Now that he was actually involved in the light-hearted shenanigans, he just relaxed mentally and let his new body move on its own through sheer (Master PC manufactured) discipline.

Part of him wondered what the primary Otto was up to upstairs with George at that very moment. Part of him wondered what Frainkie, as well as all of the other Frank-Smith-named victims who've had their minds hijacked, were doing at that very moment. Part of him knew that he was already about to fill up Nancy’s stretchy pussy with a hefty load from his bottomless balls. Part of him wanted to see exactly how his gothic daughter’s cum tasted. Part of him wondered how long the twins and their ungodly libidos would be fucking their aunt’s bimbofied body before they all passed out from exhaustion. Part of him wondered what tomorrow would bring, given that everything thus far has felt like the most vivid wet dream of his life.

Ultimately, Frank didn’t worry about anything else for the rest of the night from that point on.

He just let it all happen.

“Y’know daddy, for a straight guy, you sure are good at sucking cock.”
