Your geisha girlfriend is furiously rubbing at your aching crotch even as higher up her lips assault your own with equal gusto.
You've given up on being worried with how the cookie's magic is affecting you. The pleasurable tingles start at your locked lips and writhing tongues before sliding down to your core and exploding outwards in waves, cascading throughout your being. You moan with each pulse, feeling excited as fresh changes begin to wash over you.
You feel yourself slipping down further in size in spurts as your frame smooths and softens. One inch, two, three; you shrink down smaller and smaller. Your shoulders and torso crunch inwards, smoothing out and softening your frame. A pair of invisible hands wraps around your waist, and you gasp into Lisa's mouth as your midsection is squeezed, leaving a much smaller waist behind. Fat and muscle bubble away, leaving lissome legs and arms with just a hint of cute tone. Your breasts remain their B-Cup size, nipples buzzing madly, but some of your vanishing mass makes its way to your rear, pressing it out into a small but pert feminine derriere.
Shrinking hands crack and pop as knuckles and fingers become softer and more shapely. Your feet feel as though they are being rubbed and pressed by a thousand soft but firm hands. Small cracks emanate from your toes and arches as they become daintier, each pulse feeling as pleasurable as Lisa flicking your nipples, and you wriggle your tiny feet inside your now cavernous shoes and socks.
Now of the same diminutive, feminine stature as the geisha atop you, Lisa pulls away. As she does, you notice her tongue takes longer to exit your mouth than it normally should. Opening your eyes, you catch a glimpse of Lisa's tongue. Now fully the same pink as the cookie had been, its pointed tip danced in the air, easily long enough to lick the underside of her chin if she so desired.
Lisa seemed completely unaware of this development as her tongue started to slither back between her lips. Her lusty gaze was fixed on you, and as you watched parts of her irises began to lighten and shine dimly with a pink hue. Still staring down at you, her right hand reaches up unconsciously to fondle her breast. She bites her lip with a much sharper and longer canine than she was sporting just minutes ago, her breast surging outward firmly into her palm, pressing against the silk of the light blue kimono. She closes her pinkening eyes, tossing her head back in ecstasy, and within a moment her left hand is mimicking the process with her other breast. Lisa is soon left with a pair of firm C-Cups, their enhanced size pushing against the kimono as her nipples poke and rub insistently against the fabric.
"Lisa, your changes aren't st..." you begin to say in your higher voice, concern over the cookie's changes returning. However, the tingles that had abated for a moment arose again in full force. The core of pleasure that thrumming in your chest shifts, moving its way up your throat to your head. A strangled gasp of pleasure cuts off the rest of your words as your neck slims down greatly and your Adam's apple smooths away into nothingness, leaving your voice perfectly feminine.
With all your willpower you fight to retain your focus and keep your eyes open. Even as you stare at Lisa in the throes of passion, you can feel your face and head changing, as well as a rustling across your body as your clothes began to alter. Lisa pauses her fondling, feeling the shifting of your clothes. She casts her gaze back down upon you, her irises fully pink with a slight glow. From behind the pale coloration of her makeup, the rest of her skin has started changing color to a pinkish-red. It sweeps down her form, the exposed portions contrasting nicely with her light blue and indigo ensemble. Lisa lifts herself off your smaller frame, sitting up on her knees next to you on the bed, taking in what appear to be your final changes for the moment.
She watches approvingly as your eyes shift in appearance, growing slightly larger before becoming an inviting brown as they lids take on an Asian shape. Your jaw cracks three times, and each time it becomes far slimmer and more feminine, ending with a tiny rounded chin. Your cheekbones pull up and your nose shrinks down to dainty cuteness, while your lips press out once more, becoming eminently kissable and cementing your transition into an Asian visage. Your hair extends out further, lightening to a ginger blonde and pulling itself into a messy wide bob that reaches about three quarters of the way down your neck.
With the shifting of your face coming to an end, you lift your head slightly to get a look at your changing outfit. Raising your tiny tingling feet into view, you see your white socks extending up your legs, stopping just below the middle of your slim calves. Their fabric pulls inward tightly, fitting your feet better even as the rubbing sensation makes you bit your own lip. Your shoes, formerly size 11 sneakers for men, bleach themselves white before shrinking and tightening themselves against your now dainty soles. The design shifts, becoming far more feminine while still remaining sneakers as the laces retie themselves.
Your absurdly loose pants begin pulling their legs upwards, the tan color bleaching itself white too. The waistband starts climbing higher up your midsection, neatly tucking in the hem of your loose blue button-up shirt to sit high on your waist. The legs have now shortened so far, to the middle of your thighs, that they could now be considered shorts. That appearance wouldn't stay for long however, as the inner seams of the legs split apart, momentarily revealing the boxer briefs containing your still-intact and throbbing member as they shift into white boyshorts. The exposed fibers of your pants shudder before darting across the gap between your legs to interlace with one another. Vertical lines and folds begin to appear on its lower two thirds, flowing downwards as the shape of your new white pleated skirt flutters enticingly about your upper thighs.
The light blue of your button up shirt darkens as the fabric shifts, becoming an indigo linen affair. Splotches appear across the surface, becoming a pattern of rather large white polka dots while the buttons down the front shift to rest on the left side in the feminine style. The garment shrinks only slightly, altering to accentuate your girlier form while remaining quite loose and tucked into your skirt. The larger sleeves roll themselves up somewhat, stopping about three quarters of the way up your forearms.
Reaching a shaking hand up to your face, you pull strands of soft blonde hair out of your vision in order to see Lisa better. You stare up at her as she smirks lustily down at you. Still seemingly ignorant of her continued changes, Lisa's pink-red ears begin to grow out from her dark tresses, their black tips becoming pointed. Simultaneously, the hair at the top of her forehead begins shifting as two horns sprout, their blackened tips fading to pink-red along their length before reaching her skin.
This change seems enough to break Lisa's attention from you. She closes her eyes, furrowing her brow and biting her lip with a sharp white fang as her horns pressed out and out from her skull. Her expression seemed to be somewhere between pain and pleasure as the horns crested at three inches in length.
"Wha..?" she said, reaching a hand up to feel them. Her confusion turning to satisfaction quickly as a devilish smile alights on her face, fully revealing her set of sharp canines on the top and bottom of her mouth.
"Guess I'm still a work in progress too" said Lisa in a more sultry voice. She looked at you and taps a finger against pouted her lips, her glowing pink eyes flashing mischievously even as her nails started to turn black and sharpen, the dark coloration beginning to slowly creep down her pink-red fingers.
"But so selfish, focusing on me even when you have such a big step to take next..." she trails off, and you follow her incandescent gaze down to your skirt. There you can see the bulge of your manhood, still throbbing in time with the echoes of your transformation, each rub against the soft fabric of your boyshorts causing your hips to wriggle slightly.
"Seems you need a bit of help again..." says the increasingly demonic geisha. You open your mouth to argue but Lisa dives down with unnatural speed. In a smooth motion she flips up the hem of your pleated skirt up and pulls your underwear down. You barely have time to feel the cool air of hte room agaisnt the skin of your cock before the demonic geisha takes it into her mouth.
"Ooohhhhahhhhhhohhh" is all you are able to let out as your head slams involuntarily back against the bed. Your whole world has gone white with pleasure. Lisa's elongated tongue wraps itself all along your member; coiling, undulating, squeezing like nothing you've felt before. Your hands grab at the bed, sheets twisting between your fingers as the knuckles go white. The pressure in your cock builds and builds until it crescendos, exploding in her mouth more forcefully than you ever have, your girly hips bucking with each spurt.
The cumming doesn't seem to be stopping however, and neither does the geisha. Still sucking and working her tongue, she swallows and swallows and more and more fluid erupts from the head. Your dainty feet are twitching and wriggling, sympathetic waves of pleasure flowing from them with each thrust of your crotch.
Through the ejaculations, you feel an ache below. With one mighty thrust and an equally strong sucking from Lisa, you feel one testicle slide up into your abdomen. Another bucking thrust causes the second to head inwards as well, the pair moving and settling into their new positions.
Your empty scrotum begins to tighten, the loose skin pulling itself tight against your crotch. A separation appears down the middle, and the skin bunches up around the sides, creating the lips of your new vagina. The path your balls took widens, and you moan louder as the walls of your vagina form, pressing deeper before reaching the edge of your new uterus.
Your geisha girlfriend keeps working on your manhood, massaging and sucking at it even as it begins to shrink with each new thrust of your hips. Down and down it retreats, nestling among the upper part of your lips as it becomes your new clitoris. Lisa doesn't miss a beat as the shrinking flesh pops out of her mouth. Licking her messy lips, she extends her pink demonic tongue and greedily plunges it into your new pussy.
Through your moaning and wriggling, she masterfully she locates your new G spot, rubbing at it insistently with the dexterous tip of her tongue. What had already felt like an overwhelming sea of pleasure ignites. Your eyes fly open, still blind to your surroundings and you see nothing but stars as you scream in a girlish lilt. With a final bucking of your hips, your new pussy gushes all over the geisha's face, and your head falls back against the sheets as you pass out.
