Interesting effects

Becca took in her unsuspecting sisters. Their cheery dispositions and youthful body's all just waiting for her disruptive influence. A half dozen ideas flitted through her mind, each just as perverted and depraved as the last, causing her cock to thunder in appreciation between her firm thighs.

However she settled on something a little more… open ended.

Whenever a girl drinks a natural futanari's cum they temporarily grow a penis of their own. The amount consumed affects the size.

"Fuuuuck yessss! I loooove this part!"

Beside her, the short redhead, Annie, groaned. She shoved her chair back, squeaking loudly on the hardwood, so that she had some space between her and the table. Becca watched on with rapture as Annie's hands grasped at a protrusion pushing out in her shorts. It grew quickly, fast enough that as it created a massive bulge in the girl's pink shorts she had to pull the cloth aside, still tearing the garment as more and more flesh spilled out. What sprung forth, bouncing as it exploded in size out one leg of the torn bottoms, was what could only be described as monstrous. By the time it had passed up and above where Annie's head lay against the back of her seat, Becca had begun to wonder if it would ever stop. It surged, bouncing against her small chest each time the short girl's heart sent another wave of blood into the massive cock. Gleaming fluid slowly slid out of the tall slit at it's top end, obscured by the fact it lay several inches above Becca's eye level.

Becca trailed her sight down it's beautiful length, taking in the many fat veins crisscrossing and pulsing. Her eyes landed on the base of the 2-liter wide cock where the smooth skin met up with the girl's shining pussy, fluttery lips inflamed and dripping excessively.

Well that's no good

As Annie sat gasping and cursing, her eyes far off and in-love with the monstrosity before her, Becca typed away on her phone.

Usually girls grow balls alongside the penis transformation that stay as long as the penis is there.

As soon as she pressed enter more moaning met her ears. Quickly she turned to watch what was to unfold. Annie's knees vibrated, uncontrolled, as first one and then the second of two apple sized orbs fell to buoyantly rest in her new scrotum.

She moaned wildly, her eyes moving without any clear comprehension behind them. Two heavy geysers of clear fluid shot up and onto her body as each testicle dropped into place. Her short red hair lay across, matted on one side of her face. Her arms wrapped around, rubbing the bottom side of her massive cock ,paying attention to the wide bulge running the length of it’s ridiculous girth.

It was then that Becca began to notice noises coming from elsewhere besides the little show happening beside her. All around the table, girls that she'd known all her life moaned and gasped in their own little transformative progressions. reddened cheeks and rising chests went out among the gasping women/temporarily turned futanari as they each took part in this latest change. However even though each girl was clearly going through a similar experience to Annie, none had such a stupendously huge endowment. Annie, ever the cum-addict, had been Becca's most avid enjoy-er of the thick treat, asking the futa to load on orgasm after orgasm of sticky substance until even Becca's **** stamina started to wane.

"Holy fucking shit." Annie gasped. Her eyes cleared somewhat from the mind-shattering stupor of gaining so much sensitive flesh. With her thin frame and short stature it nearly doubled her effective body mass and cast an ominous shadow over her head.

Across the way, sitting in a much similar situation, Morgan eyed her own hard appendage. Chest heaving and lips parted, her hand hovered beside the thick bulge down her pant-leg. She’d indulged too much today, consuming more than usual of the sticky-sweet treat and now this… thing pressed outward at her straining Jeans. That was the trouble with her sister’s easily available treat. It tasted too good!

Morgan’s eyes were drawn away from her brand new dick, pulled by the sound of someone gasping loudly beside her. The girl was looking across towards where Annie had been sitting and as Morgan finally looked at the small girl she too gasped, all but forgetting about her own member at seeing the monstrosity hanging over the girl’s head. That big gleaming tip was large enough to encompass a space larger than Annie’s own face. It glittered with the constant fluids squirting out of that huge opening at it’s end.

“God, Annie, you just couldn’t help yourself could you?” Sam said, the tall and muscular girl watching with obvious delight at Annie’s difficult situation.

Annie struggled for a second, moving her head to the side as she hefted her girth to the other, it’s majesty straining up past her face as she struggled to keep it from falling one way or the other.

“Huh-ha… yeah I might have had too much…`` She tried to give a self-effacing laugh, instead pulling in a gasp of air as the movement of her body against the monster caused a ripple of pleasure to shudder through her.

Morgan shook her head, unable to pull her eyes away from the ridiculous thing. Maybe it was a sign, another event signaling the change that was taking place in their family, whatever that meant. Either way she’d never seen anyone drink so much of Becca or Brianne’s cum in one sitting and thus such a massive growth at once.

She looked around, unable to fight the urge to peek at what her other sisters might be packing after their weekly treat.

Most looked similar to herself, flustered, a bit horny and with suggestive bulges in whatever lower garments they all had on. No one could compare to what Annie was packing however. Morgan blushed, realizing that she too had more going on inside her jeans than most of the other girls right now.

Martha, the mother of all these nubile futa, stood causing her chair to squeak on the hardwood.

“Well I need to get to work girls.” she said, three tents in her luxurious cow print sweater. One at each nipple and a third where her brand new cock jutted forward.

“Whoever is on the chart, I don’t want to have to come back in to see a huge mess when I’m done. Okay?” she said, running her eyes over all of her offspring, causing the girls who’d "forgotten" last time to shrink down slightly in their seats.

Satisfied, the elder woman went on her way, sporting a boner that would put most men to shame.

Morgan frowned, remembering that it was her turn to do the “table cleaning”.

Her frown deepened when she realized how much of a mess Annie’s large meal and subsequently huge cock were making across from her.

Sam sighed, leaning back in her chair to balance on the back legs. Her muscled chest rose and fell, her expression of happiness and arousal as she looked down on her own changed physique.

“Shit, I love the twin’s cum but why does it always have to make me so fucking horny.”

“Hah. Like that’s the least of the problems to do with it.” Katie, a dark haired girl with a gothic fashion sense spoke up. She looked directly at Annie’s massive member, the monstrous rod now resting against the edge of the table so that Annie could rest her tired arms after holding the thing steady.

Sam rolled her eyes at the other’s comment.

“Yeah, well some of us have no self control. That’s as much as she deserves after gorging herself like that.”

Katie didn’t seem convinced, dark eyes still watching the pulsing tool with apprehension.

Now who was it that was supposed to help Morgan with clean-up today…

Morgan looked to where the girl who was supposed to share the severe clean-up detail with her. Jessica was nowhere to be seen.

Morgan cursed under her breath, dreading having to do two girl’s work all on her own, not to mention while dealing with her own hard dick always distracting her while she went about it.

“Hey, anyone seen the twins? I’m still kinda hungry…” a girl further down chimed in.

Morgan looked, confused for a second, realizing that she couldn’t remember seeing the pair for a while now…

With a sigh, she shrugged the thought away. She had a job to do after-all and she knew that none of the others would volunteer for the long process of cleaning up so much sticky cum.

“w-Who? What’s going on Becca?!” Brianne gasped.

Becca pulled her twin along, heart racing inside her chest as her cock bounced below her tiny skirt.

Only one thing remained on her mind right now. That image, when Annie’s soft skin suddenly erupted with vein-riddled-masculine-flesh. So hard and so…

She shuddered, nearly stumbling in her mad dash for any available space.

She stopped before a door, momentarily forgetting what was behind it as her jumbled memories mixed with the dream-like memories of Blake’s life. She threw the door ajar.

A closet. A fucking closet.

She winced, eyes diverting to look towards her confused “twin”, only serving to cause her pulse to double at the lewd visage next to her. Small tits exposed, that gigantic ass and a long cock with only that thin sleeve covering the top half...

“H-hey, why’d we leave? I thought you wanted to… you know… mess with the fam a little bit?”

Fuck.

She’d forgotten to include Brianne in on her changes to the family.

Whatever. It would have to do.

She pulled her twin inside the dark closet, pulling the door tight behind her. In that tight space, their only company that of the encompassing dark, they could feel the other pressed tight to them, warmth passing back and forth as Brianne breathed evenly while Becca’s thundering chest caused her to gasp over and over. Here, pressed to her double, Brianne finally felt the tension, the need in her counterpart.

Becca leaned forwards, her lips both right next to and so far away from Brianne’s sensitive lobe.

“I need you to fuck my ass.”

She said the words straight and filled with conviction as if it were her one life goal. Yet there remained that undercurrent, the arousal that so obviously had consumed the futa at this point.

Immediately both futa’s dick’s pulsed in the dark, their breathing growing audibly louder.

Brianne chuckled, licking her lips.

“I’m only too eager to agree. You need my long hard dick in you’re virgin little ass!” She said, chuckling as her body responded to her alluring twin.

Becca groaned, the noise high pitched so it almost sounded like a whine, reacting to the lewd back and forth.

Brianne hefted her dick, sliding the sock-covered end over her sister, stepping back so she could tease up the other futa’s thigh and towards her own member.

“Now. Turn around. I want to feel up your tight little ass.”

Becca complied, shuddering as the long dick rubbed across her thigh before eventually resting atop the shelf of her athletic bum.

Brianne however was not done with the girl. She slowly moved downwards, directing her dick to trail down and across the “slit” of her anal hole, causing yet another high-pitched whine to come from the to-be fucked futanari.

Finally she squatted, long cock dangling out into the dark between her twin’s spread feet on the floor. Her hands rested on the plush skin of Becca’s ass, circling slowly for a second as she took in the feel and the scent of her aroused sister. She could barely see, with the only light coming from under the door and only dimly at that. Still, with the girl’s ass cheeks in her hands it was fairly easy to figure out where the prize lay.

“But first I want a taste.” Brianne licked her lips hungrily before diving in.

“HuOH! SHIT!” Becca nearly shouted, jolting forwards as the tactile feel of Brianne’s tongue explored a space that Blake had never even dared to think about. It was vile, wrong, disgusting… and she fucking loved it.

“oOOh my fUck!... yeah-unngh… just like that! SUck on my-OH… dirty FUcking hole!”

Brianne had never tried this, tonguing another being’s ass, but she’d fantasized of it plenty, exploring the idea as she tongued her own cock’s opening. That combined with her long years spent sucking her own dick meant she soon had Becca’s own dick spurting heavily against the wall in front of her.

There wasn’t much space to move around so as Becca slowly came down from her first rim job she began to slump against the wall, only held up by Brianne’s face in between her cushioned cheeks. Long dregs of cum drooled all over before her which she soon knelt on, mucking up her knees and her half-wilting dick which continued to jolt forward with streams of cum.

Brianne continued on, experiencing a high of her own at the perversion of having her face in between what was essentially a clone’s plush ass-cheeks while she tongued the little star within. Not to mention that the longer she kept going produced even more mewls and moans from the girl that, according to what Brianne could hear, was still cumming.

Now laying in a pool of her own semen in the dark, Becca groaned as Brianne finally pulled her face free with a wet noise so lewd that it caused Brianne’s own cock to surge slightly.

She could just make her out there, laying, slight movement showing the rise and fall of her chest.

“Mmh hm... not yet little girly.” Brianne said, holding her cock still with one hand as she pulled the sock free with the other.

She tossed the thin sleeve so it landed on Becca’s head.

She leaned over the girl, placing a hand beside the resting futanari’s waist, her fingers catching some spunk as she used the other to line up her obscenely long dick with the place she’d just tongue fucked.

“I haven’t even done as you asked!”

With that she shoved forward, using just enough **** to push within the slimy pulsing star and sink in another inch.

Becca immediately lurched in place, back arching and eyes widening in the dark space. She yelled out, her voice high and surprised at first. From that first thrust, Brianne halted, actually thrown off slightly by the sudden noise. It had been loud enough that it actually hurt her ears. However whatever worry that she may have initially felt about the situation quickly faded as Becca’s short scream soon turned into the now-familiar sound of her moaning in excitement.

“I..iits… soOooo wrooong…” the futa continued, now moving her hips to allow Brianne’s dick to wedge further inside herself.

Hell yes, it stung, the initial pain enough to make her forget the pleasure, but now the mixture, of pulsing pain mixed with the perverted knowledge that she was being anally fucked by her new twin…

“Deeeeper…” Becca gasped, her lips stirring up her own seed on the floor under her.

“Gladly.” Brianne replied, a smile in the dark as she backed up before slowly pushing forward, spreading her double’s virginal ass slow enough for them both to savor every perverse moment.
