Heather groaned as she sat up in bed. By her side, Yume also squirmed with her arm resting over her daughter's thighs. The teen merely sighed, recalling everything that had happened up to that point and knew it couldn't be denied; it had all been far too real. Just to prove it to herself once again, Heather raised a hand, seeing her normal tanned skin. With a blink of an eye, she was blue and slightly see through. Nothing about what had happened made much sense to her, but she knew the gist of it.
Her mother, who laid naked by her side, had invited Heather's class on a trip to her lab. It was free and educational, as such the school board had agreed in a heartbeat, particularly since Yume was a parent to a student. And then, within that lab run by her mother, Heather had stumbled upon an unstable experiment. It was a liquid, which, put simply, found its way into Heather's body and turned her into something of a slime girl. Now, after a certain series of events, she had altered her mother into, for lack of a better term, a food source. Said source turned out to be a Futanari who produced excessive amounts of semen.
Heather carefully moved Yume's arm away and stood up. She stretched and turned back to her human body, though it felt odd to be in such a state. Even though she was born that way it didn't feel right anymore, like when you're so used to something and it suddenly gets replaced entirely by a different version of it. You know it's the same thing in a way, but it's impossible to get used to. A poor explanation when compared with her situation, but it was satisfactory. Heather gave herself a once over.
It didn't seem like she would need to shower ever again. Her hair was perfect; silky, straight and styled just how she liked it. She sniffed herself, finding that her body odour was just like her usual wash. Everything seemed to be in tip top condition with no need for her to maintain it. Not only that, but she didn't feel hungry in the slightest, well, she was pretty thirsty. As if in reaction to her need, Yume stirred on the bed, sitting up and setting her gaze of on her daughter. She grinned widely.
"Morning, honey. Want some breakfast?" She asked, knowing full well what it entailed. Heather glanced around nervously, biting her bottom lip. Even if she knew what she needed to stay healthy, it didn't make it any easier to accept. Her eyes inevitably fell on her mother's cock, the now nine inch cock hard and waiting for her decision. Gulping audibly, Heather crawled back onto the bed. Yume happily spread her legs, moving up to the head of the mattress to give her child better access. She knew it was wrong, but her body's needs couldn't be denied.
She stared at her mother's cock. It was so hard, throbbing visibly and already leaking thick pre-cum. Yume was clearly looking forward to this, but knew Heather would take what she wanted. Yume had no say anymore, all she could do was offer herself to her daughter. She couldn't quite explain it to herself, but since Heather had given 'birth' to her last night, she wanted nothing more than to pleasure and obey her child. Even now, as she was about to once again commit an incestuous act, she could only feel excitement at the prospect of feeding her precious daughter. The slime girl opened her mouth and took the entire nine inch shaft inside.
Heather no longer possessed a gag reflex. Her transformation having removed the obstruction to her nourishment. She didn't care, as she engulfed the entire length, immediately soaking it in her copious spit, which, like her juices, worked as a potent aphrodisiac and temporary enhancer. She didn't know it yet, but her fluids were powerful enough to make an exhausted man spring back to life and increase their cum production several times over. And, despite her production already being extremely far above average, it had just as potent an effect on Yume. The Japanese mother moaned as her daughter used her.
Every time she took it all, Heather felt the cock pulse harder and faster. The veins throbbed against her tongue and lips, sending sparks of want through her body, even if they were morally wrong, not that it mattered to her. Those morals were for humans and she was obviously not human anymore, neither she nor her mother could find it in themselves to truly care. As Heather once more thrust her face down, her throat being filled once again by her mother's new prick, she found the sensation was actually pleasant. Perhaps she did possess a gag reflex and it had just been altered to derive pleasure from such an act?
Either way, she could feel the warmth of her arousal rushing through her. As if in reaction to her growing desire, her body changed back to its newly natural state, her blue hands lightly gripping Yume's thighs. The contact sent a wave of lust through her body, making her cock jerk and release a large spurt of pre-cum into Heather's lustful maw. She felt it sliding down her throat, settling into her stomach and sending a small wave of warmth and lust through her body. A shudder of desire ran through her, creating ripples through her liquid form.
Instinct drove her movements. Her lips wrapped tight around Yume's prick, massaging the throbbing shaft as her tongue lathered it in her affections, driving its owner closer and closer to climax. She moved her hand up her mother's thigh, every inch she moved forcing her cock to pulse strongly and send a spurt of thick pre down Heather's eager throat. Eventually, the slime girl's hand cupped Yume's twitching balls, the aphrodisiac striking her to the nerves like a bolt of pure pleasure. The Japanese futanari released a cross between a gasp and cry of building ecstasy.
Heather looked up at her. The slime girl's glowing, ocean blue eyes alight with her desire, the speck of bright azure in the centre of her pupils shining brighter now. Yume couldn't hope to resist her, even if she weren't under her daughter's control, she wouldn't be able to. That gaze held all the power of a God's stare; commanding, dominating, and utterly impossible to refuse. She knew her child needed her to cum, if only for her meal, but that didn't matter to Yume as she cried out in bliss. Her cum raced up her length rapidly to spray into the depths of her daughter's body.
If her angle of view had been better, she would see it as her semen gushed down Heather's throat. The opaque fluid, tinted a deep, cobalt blue by her skin, filled an invisible orb within her. Later, when Heather saw her reflection, she realised that her organs had simply blended into the colour of her skin, hardly visibly without looking closely. But now, it was clear where her stomach was as it filled and swelled with her mother's seed, whose massive balls were beginning to gradually deflate as she unloaded into her. Heather moved her other hand and dipped a finger into Yume's pussy. A giant burst of cum caused her belly to swell even larger.
On and on her orgasm went. Yume laid back into the bed, breathing heavily from the pleasure, her cock still sending spurt after spurt of cum into her child, the amount hardly decreasing over time. Of course, it couldn't last forever and her orgasm came to its end. Heather pulled out the rapidly deflating erection, sucking as she did so to draw out the final dregs of Yume's semen. She sighed happily as she laid back on her hands.
Lethargy rolled over the both of them. Despite both no longer being entirely human, they couldn't help enjoying the aftermath, even though Heather herself hadn't cum. The feeling of all that semen inside of her was delightful, in a strange way, like the feeling one gets after eating a large meal. She even felt like she could happily fall asleep then and there, however that day was a school day. With an exasperated sigh, she grabbed her phone, once again surprised that it stayed completely dry despite her aquatic state of being. Checking the time, she saw she had fifteen minutes until first period.
In an instant she was on her feet and back to her human form. She rushed to her closet, searching frantically for any clothes that would even fit on her new figure, however nothing quite did. The best she found was a shirt that, barely, covered her entire torso with her chest stretching the fabric. She didn't have any bras that could fit, no matter she may try. None of her pants could hope to fit around her shapely hips or conceal her cock, which had grown somewhat. Yume, having ever the analytical mind, estimated her daughter to be at least a foot long, despite it being entirely flaccid. Both of them were interested in what it could be when erect.
Heather decided to pull on a knee length skirt. To her fortune, she had a pair of panties with some real elasticity, able to fit her cock and balls in them like a sling. It wasn't entirely comfortable, however practicality took precedence at that time. Her panties should be able to keep her cock from view, however only a fool goes in without a contingency plan, hence the skirt. She checked herself in the mirror, finding that her body had changed ever so slightly since yesterday.
Her mind had apparently come to terms with all that had happened. The fact that she was an inhuman creature no longer seemed alien to her, nor was the fact that she had grown a penis and her breasts had substantially developed, as had her hips and rear. Her face hadn't changed much, save for her glowing blue eyes, and neither had her height of six foot nothing, but her breasts now fit her stature much better. The F cups sat proud on her chest, sagging just enough and capped by her large, silver dollar nipples. She had admit she was glad to have a rather impressive bust now.
Her waist was as slim as ever. The only change around her middle was that it was slightly softer, her six pack no longer nearly as visible as before, though it was still there if one looked close. Her slender midriff was accentuated further by her now wider hips, which had just enough flare to give her a decent hourglass figure. Her ass had seen some of the best improvement.
It was rather shapely before. Nicely curved, firm to the eye and touch. Now she had a good deal of padding to her buttocks, the skin smooth and free of any blemishes like every inch of her altered body. She'd always been good looking, there was never any doubt about that, but now was like a whole new level. She had never noticed it before when looking in the mirrors, distracted as she had been by her new eye colour and changing body, but her face looked slightly different. Her cheeks were a little fuller than before, with a natural blush to them, her lips looked slightly bigger, kind of pouting in a way. They were a pale shade of red at that moment.
Heather suddenly thought about an interesting idea. Focusing her attention on her lips, she imagined them turning to her slime state, but the rest of her body remained the same. For a while nothing happened, but, after a long blink and a sigh of exasperation, she saw that her will had been obeyed. She raised a hand to them, her full lips now a dark blue colour. They looked even more solid than normal, something to note. She turned them back and raised a hand.
