Sisterly bonding

Nabiki gasped loudly as she made it to her room, she saw Akane slamming her door angrily and silently while a trail of pre-cum slathered the floorboards beneath her. Her dick lead the way, not even paying attention to the nearly silent muffles from the lifeless plush fuck doll cradled under her arms. Grunting, she fumbled with the latch and slammed her cock directly into the door. Not even noticing the faded stains from past occurrences.

Her mind was ablaze, single and simple thoughts had overloaded her synapses. Even before she was turned into this big dicked fuck hound, she’d always been a bit self indulgent with anything that pleased her. What would be the use of all the cons and scams and schemes if not to fuel her rich tastes and wonton pleasures? She would treat herself well, that included carnal pursuits. Men were useful as walletts and for being handsome, cute, occasionally debonair, but what really got her motor turning was the pursuit itself.

The chase of a con turned her on like none other, she’d touch herself while planning elaborate schemes that raked in the big numbers. The more fantastical, the more pleasurable. Her favorite pastime with her personal massager. Now however she had a new outlet, a new pursuit and a whole new orientation. She couldn't tell if the presence of a cock had magnified the niche kinks and desires she already had or if they were something new, neither was at the forefront of her mind as she finally opened her door and nearly tripped inside.

Her dick throbbed obscenely, balls full and pulsing against her thighs. Stumbling across to her bed and tossing the doll onto it, it splayed across her sheets face down and ass up. The flimsy and frilly skirt exposing the pointless clothes it was wearing, she’d seen those panties before. She always found it funny that her sister wore those typical blue and white striped panties you’d see in anime and hentai. Her hands trembled, her heartbeat was pounding in her chest along with the incessant throbbing in her loins. Am I really going to do this? Nabiki gasped mentally. The temptation was so overwhelming, the need all encompassing…

However…

With immense trepidation she flopped the doll over and gently set it back against the headrest, smoothing down the folds of her skirt to keep the modesty of the doll, despite the baby doll nightie she was wearing frumpled around her waist and exposing her plush and firm tits to the air. The only sound in the room was her ragged breathing and the dull ache of her own heartbeat pounding in her ears.

Kasumi lay still, as...as a doll. Unflinching, unbreathing, unresponsive and unblinking. Not a sound nor a solitary twitch. Just a gently smiling pile of fluff, fabric and...latex and rubber. A pillow made to entice with zaftig curves and firm toned cushion. The holes molded in the shape of her lips and sex called out to that primal part of her, echoes of a memory rolling through her subconscious of familiarizing herself with all the contours of her sisters specialized orifices.

Her “face” was nothing more than a flat simulation of her normal placid and oblivious expression, that calming one that made everyone feel at peace. It was situated as a cartoonish example of her new form, nothing more than a pattern upon fabric.

“Hey...uh...Kasumi?” Nabiki ventured, knowing that at least upon example that she was lucid albeit only when directly addressed. She felt her breath catch in her throat when she saw a vivid color come to the face on the dool, and its eyes animated oddly. Nabiki did her best to stall her lust, losing battle as the tip dragged roughly across the bottom of her shirt staining her vest.

The dolls animated features cast down to look at her throbbing member, her “mouth” flexed slightly as “Mmm Mmm” moans emanated from within. They sounded muffled, and slightly echoey.

Nabiki could hardly believe what she was witnessing, her older sister was nothing more than a fuck toy. Her personal fucktoy, as she remembered from those vivid flashbacks running through her mind. She didn’t even know where to begin, or how to even approach a situation like this. Reality itself was in flux in perverse ways, and yet no one was the wiser despite the insanity of the changes. She squirmed in her seat, shoulders shivering as thinking about it served to only arouse her ever further. What could Nabiki even ask or say to her sister, who had gone back to being completely inert now that she had lost focus.

“Hey hey!” She snapped her fingers, making the dolls' face animate again.”stay with me Kasumi...geez umm...do you ...know where you are?” she wondered, the eyes on the doll “blinked” in a way, tilting in puzzlement as if she was asking why the sky was blue.

“Mm” she responded, as if that was all that needed to be said.

“Sigh...of course, you don't think anything’s weird either do you?” She thought internally. Watching that same expression of confusion come across her printed features. The inner folds of her mouth crinkled as if she were pursing her lips, Nabiki gulped when her cock throbbed stronger at the sight. Ugh relax Nabs you’re stronger than this she told herself, knowing that while her willpower was high...that seemed to be the old reality. This new reality she was as shameless as could be when it came to sating her baser pleasures. Kasumi didn't seem to mind or at least expected this scene as normal, not even bothering to cover up her erect cock as she faced her.

“Do you like this?” Nabiki wondered, as the “Mm” sounded in the affirmative it seemed. She could tell that she was somewhat distressed to be used as seating under Ranma's...succulent ass…What I wouldn't give to have her sit on my face..Mmmm Her hand instinctively glided along her cock head, rubbing it as she imagined her face encased between those beautiful cheeks and-

Shit! she got distracted too easily, by the time she could think again it’d probably be past midnight. She needed to focus, and as much as she wanted to. The feeling of her warm delicate hands on her cock was too much for her, opting to stroking it softly rather than remove them. She couldnt believe herself, sitting in her room “talking” with a sex doll of what used to be her own older sister and fantasizing about getting her face sit on by the gender bent form of her younger sisters fiance. Letting out a dramatic sigh…

“I really am that perverted aren't I?” She said, as the strokes along her cock got longer, harder and more lavish. Closing her eyes as a heat built up under her palms and the iridescent flashing of green lights clouded her vision momentarily. Kasumi remained a silent observer, her mouth hole pulsing idly while watching her sister masturbating for her.

“Mmmmmm fuck” Nabiki moaned loudly, not trying to keep her activities secret. She knew the rest of the family would hear her, and she really didn’t care. In fact letting them know what she was doing only made the act hotter for her, she fell across the bed at the feet of Kasumi’s doll form. She crawled across the surface to meet her, one hand pumping her cock and the other slick with her precum roughly groping the soft curves and contours of her personnel fuck toy. “Kasumi '' she whispered fondly, knowing that each time she said the dolls name the sentience of her sister would awaken.

“Mmm...Mmm” Kasumi moaned happily at the attention, proud to be of use to her owner. “Mmmmm! Mmmm!” she mumbled pleasantly, Nabiki's hands squeezing and squishing the expanse of her pillowy tits.

“Kasumi!...ugh...yeah Im gonna fuck you so hard” She whispered, dry humping the silky smooth cloth of her body. She practically ripped the flimsy clothes from her sister's body, discarding them wherever they may fall. Working her way up, not sure if she was edging herself or teasing Kasumi. The thought of making the immovable doll hunger for her touch, sent a thrill through her body.

Nabiki had always been jealous of Kasumi’s figure when they were growing up, always wondering when she was going to develop the same way. Now she couldn’t care less as she straddled her lifeless form, staring into the sparkling print of her flattened face. She leaned down, inhaling deeply as she licked up the moisture that had yet to dry from Ranma’s needy cunt grinding atop Kasumi’s face. She could see drops of Ranma’s juice collected into her face hole, Nabiki’s eyes dilating as she spotted it. Her dick sandwiched between her waist and Kasumi’s, feeling her hot seed absorb into her plush skin. Nabiki made out with her sister's silicone face hole, her tongue feverishly digging into every crevice searching for more of Ranma’s sweet pussy juice.

Any moral issues she had about fucking her sister turned fuck doll had vanished, she was her fuck toy now. A mastubatory aid specialized just for her, and the knowledge that she was the only one to remember who she used to be only made her cock throb harder. Taking one hand, she lined herself up with her silicone pussy, and drove it home. Impaling her sister's inert form as it jumped up the headrest from her forceful pumping, rocking the headboard loudly against the wall. Everyone in the house would know what she was doing, and who she was doing it too. She didn’t really care.

She was the alpha of this house after all, she growled and panted hotly. She had the biggest pair in the house after all, Sure Ranma’s was nice...but she was the real Wild Stallion when it came down to it. Genma and Soun were pathetic wastes of masculinity, she had more manliness in the tip of her dick than they had in their entire bodies after all. Nabiki began to drool, rubbing her face into the crook of Kasumi’s soft neck. God, this feels good...I wonder what it’s like to fuck the real thing she grunted, picking up her pace.

The creaking and banging of her bed could be heard thumping in her own ears, drowning out her own thoughts. All she could focus on was fucking, thrusting, pounding and the bliss of having every inch of her cock milked by the only movements Kasumi was able to control. The vibrating pussy was a nice touch, especially as it oscillated around her dick. Every thrust became rougher, feeling a heat building up behind her balls. The skin around her taint clenching tightly, pulsing her testicles with fresh churning seed.

She opened her eyes, “Kasuuuummiiiii” She hissed out, staring directly into her sisters face as she pounds her. Kasumi awoke to being called.

“Mmmmmf Mmmmff” She moaned pathetically. Nabki laughed, repeating her name over and over again to keep her active and lucid. Hearing her muffled grunts served to throw her over the edge.

“Ugggghhhhhhhhhhhhh!!” She crowed, drawing out a loud and obvious moan. Her climax burned her from the inside out, enveloping her entire body in a warm ache. Squeezing her sister's malleable body up to her chest, burying her face into the pillows of her breasts and losing herself to the release in her groin.

“MMMMMmmmmmfffff” Kasumi squeaked in unison.

Nabiki wasn’t prepared for the influx of pleasure assaulting her senses, and her increased virility made her let loose multiple loads into her sister's body. Her dick was at least four times more potent than the other men of the house thanks to her careless wording, giving her a short refractory period and multiple orgasms with thicker and longer loads.

Kasumi would have sighed had she had the ability to do so, but she was content to be her pillow for tonight. She loved being used, and especially by one of her favorite Tendos. The father was just so spineless for her to be used by him, the younger sister was disgusted by her. But Nabiki, she could tell that Nabiki loved her the most.

“Uummmmff Fuck yeaaah!” Nabiki groaned atop her, filling her with a fresh load of sweet Tendo baby batter. She reflected back on growing up watching her sister mature while she prepared breakfast and…

That wasn’t right, she was a doll...those were just silly day dreams.

She would often daydream of a life where she was their caretaker, it almost seemed like a distant memory. But she had always been a faithful and loving doll for the Tendos.

There was more though, the doll reflected on hazy shadows of being Nabiki’s sibling rather than her sex toy, no..she was more of a toy first right? Her thoughts were muddled, every time Nabiki pumped more cum into her silicone loins a bit of her memories evaporated, replaced with something far simpler...like when Nodoka would set her at the dinner table every night so she could feel like part of the family…she just wished that Ranma would stop rubbing her runny pussy on her face during dinner...that didn’t seem proper of a young lady…

“God! Fuck! Kasumi!” Nabiki panted, still thrust away. Her climax continued like it always did, until she drained her balls completely into her body.

Did that make sense?

More and more of Nabiki’s seed pooled into the depths of her silicone orifice, she purred internally at the feeling. She’d cherish this load, savor it at least until Nodoka cleaned her out. She loved the feeling, wishing she could have pulled out and cum all over her tits so she could absorb it through them. Kasumi wanted nothing more than to serve her owner.

Now that she wasn't being addressed by her anymore, she could feel the pleasant fog creeping in as she went back into her hibernation trance. Those distant memories of some alternate reality of being a human fading as more cum leaked straight into her depths.
