Ace finished up and turned off the stove. He spooned some of the mac&cheese onto a plate along with some french fries that he'd found in the freezer and fried up. He wasn't exactly good with kids but he did know that every kid liked mac&cheese and french fries right? Yeah it wasn't that healthy but it's not like he was babysitting this girl after tonight. He set it on the table and then poured her some fruit drink in a cup before taking out a folded paper with a powder in it, unfolding it and dumping the contents in the cup. He set it next to the plate and called out, after going through his what the hell her name was. "Poppy! Dinner's ready" he said. He'd actually been nice to her all night, or to his best effort. After all, she may not know she was a test subject, but when the time came he wanted her to be able to trust him enough to come to him when it started to kick in. Once she came down he'd let her know that he'd be in the den watching TV.
	The little zebra girl smiled happily as she came into the kitchen, "Thank you mister Ace!" she said with a smile, before happily digging in, enjoying the unhealthy meal in the way that only a little kid could. After a bit she put her dishes in the sink and came out to the living room,, "What'cha watchin?" she asked, looking to the TV.
	The horse sat slouched on the couch,holding the remote and flipping the channels and for the fifth time, wished the woman kept beer i her house. he looked over at the girl when she came in. "Nothing. Isn't anything good on." h said then perked. "Oh oh yeah did you... Right, did you do your... your homework?" he asked. Remembering the zebra asked him to do that.
	"I did it when I got home mister Ace." she said, sitting down on the floor, looking between him at the TV. "That juice tasted a little funny tho." she said.
	 Ace took a sip of his not-beer and looked at her. "Hmm? Oh yeah... well I don't mix fruit drinks a lot. I probably put to much" he said. "Did it taste bad?"
	"No, just funny." she said, sitting with her knees tucked up to her chest. "can we watch a movie?" she asked, looking to him innocently.
	 Ace used his mouth and eyebrows to shrug. "I guess, go ahead and pick one out" he said, watching her for signs of when it'd start kicking in.
	 The girl nodded, squirming a little as she went to go pick out her favorite movie, some fairly ordinary kid's flick. once it was set up, she walked back over, squirming a little, adjusting herself in an unladylike way. "I feel kinda funny mister Ace." she said, before suddenly sitting in his lap.
	Ace finished his not-beer and set it aside and pulled out a voice recorder. "That's fine..." he was gonna finish with her name but already forgot it "... maybe you just ate to fast" he said then hit the button. [Little Z, beginning signs ten minutes after consumption] before setting it aside and then holding her hips and grinding his bulge into her butt. It bulged his shorts simply because of how big it was.
	She squirmed a little. "Mnff... what did you say into that thing Mister Ace?" she asked curiously, her attention divided between him and the movie as it started up. "My girly place feels tingly..."
	Ace continued to rub it there when he picked it up again. [Little Z stated tingling in the groin, possibly arousal] he said before putting it down and unbuttoned her shorts. "Tell me about the movie kid. What's it about?" he asked, holding her in one big hand and pulling her shorts down with the other.
	"Its-Its about uhhnn... its about a s-sailor and a girl and therefs... therefs..." she trailed off, wide eyed as he yanked down her shorts, her cunny on full display. "Why-why did you take my shorts off?"
	But Ace only licked his lips. This may be for research but he wouldn't lie, this was for pleasure to. He then brought the petite girl to his big horse mouth and started devouring her pussy and ass. (not actually eating her, just giving her some extreme oral) after a bit of that he popped his mouth off her and then held her in one hand again. [Confirmed Little Z was aroused. And her vagina and sphincter are stretching nicely] he said. While licking her juices off his lips he used his free hand to undo his pants and flick out his cock.
	Poppy gasped and squirmed, "Mister A-aaahh!" she yelped, as his tongue plunged into her surprisingly wet cunny,  "Mnnf... w-why are you licking?" She asked and groaned, writhing a little. She went wide eyed as he pulled out his stallion-hood, stunned by the sight of it.
	Ace murred and pressed her to his big cock, murring from just her little body pressing against it. [Mmm, begging with pleasure phase on Little Z] he said before pressing her little maw to his cock and stretching it as wide as it would go to stuff his cock inside, making his cock stuff to get in. [-groan- Stretching effect doesn't seem to work mmmf as well as intended, but Little Z still seems capable to stretch wide enough. Will proceed with length test with some caution] he said before stuffing more of his cock down her throat.
	The girl tried to resist at first, before eyes going wide as that cock forced it's way into her mouth, swallowing involuntarily as that cock pushed down into her throat. Her arms and legs flailed weakly in her confusion.
	Ace grunted over and over again, stuffing into her over and over. He was able to stuff all his cock down her throat but didn't note because right when he did he grunted loudly and came hard down her throat, dumping enough cum into her with his first batch to bloat her belly but not enough to cause effects yet. After panting he finally picked up the recorder. [Little Z successfully took the full length and the first load. Continuing pleasure phase" he said before pulling the girl off his dick, making her cough and snort up cum before turning her around a bit then stuffing his cock against her cunny and popping his huge cock into her. "MMmph, fuck I love my research" he growled before shoving into her womb.
	The girl gasped for breath, eyes wide. "Nnff... m-mistaaaaaahhhH! "she howled out in surprise, feeling that thick shaft spread her small cunny wide open, coughing and spitting up a bit more cum.
	The horse blew air out his lips and began humping the little zebra, his large cock glorped and slished in and out her young baby maker. He held her in one hand while humping her, easily keeping a grip on her and kept the recorder close at hand. [Little Z... has taken the full length... in her vagina well... next orgasm should show... results] he grunted into the recorder. "Ah yeah, moan for me girly. Make it sexy, want to pump as much mmph cum into you as I can" he said.
	The girl moaned and writhed ."Mnnfff... M-misteerrrrr!" she moaned out, pussy twitching around her cock. She flailed a little more, mostly useless. "NNnngg..."
	At about the time of her grunt Ace was grunting as well and soon shoved in and came again, he grunted hard and tried to watch. Her belly swelled more and more, making her gut hang down her crotch a good ways before cum started drooling out her mouth, ears, nose, piss hole, then soon her unopened tailhole. Then he could see it coming from her tear ducts and he moved his hand to find out her sweat was a lot thicker. [-pant- -pant- first results show success. Will watch a bit -pant- longer]
	Poppy groaned, gurgling and sloshing as she squirmed on his cock, feeling her belly distend so far outward that she looked very pregnant. Cum flowed from every hole on her body, even leaking from her nipples and belly button. She didn't know what was going on but it was starting to feel good, her grunts turning into gurgled moans, her tongue starting to savor the taste as it flowed up and out of her throat.
	Ace stopped panting. [All initial results on Little Z show success. Will watch her for the next couple days] he said before putting the recorder in his pocket and pulling her off his dick. "MMm now that the experimenting is over for now, just gonna make you my little fuck toy until your mom gets home" he said and then shoved her down on his cock, easily done thanks tot eh leaking cum, then reached around and started fingering her belly button with his large finger. While pumping her up and down he switched between fingering her navel and her urethra. He turned off her kids movie and turned on COPS since nothing else was on and watched it while continuing to use her for pleasure.
	The girl gurgled and writhed, not knowing what he meant, but knowing that she was starting to love this. "Mnnnff.. y-yess mister ace...." she panted between grunts and moans, feeling him slam her down on his cock over and over.  The fingers in her navel and urethra, lubed by cum only added to the pleasure, as if every hole on her body was now just a new fuck-orifice.
	About five minutes later Ace noticed something odd and pulled out the recorder again. [Little Z appears to have groan an extra vagina as well as an extra sphincter under the others respectively] he said then put it back up and tested each new hole finding them fully functional. Once he found that out he began fucking them relentlessly. "GOOD side effects" he yelled cumming into her again, by now her belly was the size of a beach ball, way to big for a girl her size to even drag around. Plus her arms and legs and neck seemed to be swelling as well, her holes were leaking a bit more now, but not much more, so Ace was easily able to cum fast enough to make her grow and grow. "MMm yeah, got you this big in just fifteen minutes, and it's still another hour before your mom gets home" he said before pulling out and shoving his big cock into her belly button and fucking it relentlessly, making cum splurt out of it while he did. gTell me about your mom, little zebra. Your mom must bring men home. What does she do with them?h he asked.
	 The girl gasped and moaned as she became more and more stuffed with cum, audibly sloshing with each of his powerful thrusts ,cum gushing from every single hole on her body, cum gushed all over the living room. The girl panted and gurgled, taking a minute to register the question ."Mnnff... s-she likes to play with their thingies... and likes it when they put it into her nipples.... and- and then they  mmmff.. go into the bathroom and he gives her a shower..."
	 "Nipples huh? She must be a former slave, or former test subject. She'll be perfect for testing, no doubt she'll be easy to coax into a daze for my cock ", he said before moving to her head and shoving his cock don her ear and fucking it.
	The girl writhed and moaned, eyes crossing as he shoved his shaft into her ear at such an angle that it ended up going down her throat. "MNnfrrr..... yo-you're gonna fill her with goo too?" She gurgled.
	Ace chuckled. "Yes I am. But I'm testing something different with her" he said.
	The girl gurgled and moaned, lost to the pleasure of being taken in holes that had just recently become sexual organs


-------------

	 Ace panted and pulled out, cumming the last of his latest orgasm onto Poppy. He panted a bit and pulled out the recorder. [Little Z appears to be a complete success. After thorough testing her body has shown perfect status as an onahole. After a couple more test subjects I'll patent it and put it up for sale] he said before putting it away. he picked up Poppy and started walking her outside. It wasn't easy, she was full of enough cum to fill a tub, but the horse was rather strong. Once in the back yard he started squeezing cum out of her by holding her belly and simply pressing his hands together. "Alright kid your mom will be home soon *SQUEEZE* and may not be best to have you *SQUEEZE* all bloated when she does." His squeezing was making cum shoot out all her orifices. "And I have plans for when she gets here" He said then picked her up in both hands, holding her torso on each end before twisting her body. "And I have you to thank *twists* because your information *twists more* will make this far easier" he said and twisted her more. By now she looked like a Twizzlers only a lot more twisted, and in doing so cum oozed out all of her body, much like a sponge. He wringed her out very tightly before letting her body snap back to correction.
	She groaned and coughed a bit, shaking her head as he let her go. "H-how did you do that to me mister ace?" she asked woozily, feeling over her newly squishy body
	The horse had her head palmed to hold her. She was now pretty indestructible, but she wasn't death-proof. For example, her body still needed her head to live and she couldn't grow back something if she lost it. "MMm you don't need to think about things like that anymore kid. from now on you're my fuck toy. Your only concern should be my cock" he said and put her up to his half hard cock and started slipping her onto it. Because of her new state and because his cock was only half hard, she slipped onto it easily, very similar to putting a sock on your foot. It ended with his cock poking out her mouth and her body disappearing into his sheath up to her neck.
	 The girl groaned and gurgled as she was pushed onto his shaft, seemingly still in shock about all of this. As the huge stallion slowly grew less hard she was pulled into his sheath, her body scrunched and crumpled up inside his sheath, just her head poking out and holding his cock like some sort of lewd sheath.  Hesitantly she licked gently at his cock.
	Ace murred and pat her head. "MMm good toy. I'll think of a name for you while I wait for your mom" he said and pulled his pants up and let the last thing she saw for now be the backyard and a zipper rise up and close her into darkness before a button snap and the tingle of belt metal. Her head made a bulge in his pants of course. He then walked back inside and slouched on the couch to watch TV before the mom arrived and for the sixth time, wished the bitch had beer in the house.
	The girl could only suck on his cock head slowly and weakly, confused but lost in a haze of pleasure and masculine pheromones. A few hours later Terri, the girl's mother, returned home, adjusting her dress a bit as she came in the front door. "Ace?" She called out. "I'm home, how's Poppy doing?"
	Ace heard the door open and her come in and call out. he turned off the show he wasn't watching and stood up. "Evening miss...uh..." yes he'd forgotten hers as well. "Good evening! Glad you're safe and sound. Um... Poppy is sleeping soundly, I can assure you: he said. Which wasn't a lie. He could tell by her lack of suckling, her slow breathing and her lack of movement that she was. He then watched her close the door and started undoing his belt. "Everything went as good as hoped" he said, pulling down his zipper, showing Poppy's head. He then groaned as his cock slipped itself and her out it's sheath but stayed soft so it hung down. He then reached down and pulled her off his cock. Waking her up from now on would be very difficult, but he was aware of this and wasn't put off by it. After all he could certainly use her for a fuck toy regardless of if she was awake or asleep. After doing that, his large and flaccid oh so yummy looking cock was hanging out in the open.
	Terri was stunned, staring at the girl as she was pulled from the huge scientist's sheath. "Wh-what did you do to her?" she stammered, one hand rushing to cover her crotch, betraying her arousal.
	Ace murred at the sleeping zebra girl, putting hr pussy to his mouth and ate her out a bit while the mother stammered her question, doing it for the sake of the girl's good taste. "MMM yummy. Just furthering her for science ma'am" he said and plopped the sleeping girl down on the nearby chair, still not waking her. he took a couple steps closer to the milf zebra and presented up his cock. "Something I intend to do to you to"
	Terri gasped, watching in mixed shock and arousal. "S-science?" She asked hesitantly, her free hand moving up to her ear, where once there had been a piercing of a particular kind. "W-what? Why us?" she asked worriedly.
	Ace shook his head. "Nothing personal if that's what you're asking. You just happened to ask me to babysit and now I'm just taking advantage of an opportunity that has been handed to me on a silver platter" he said, placing a big hand on her shoulder, it's weight only almost enough to make her kneel, with a nudge he'd have her kneel, putting his big flaccid organ right in front of her. "So tell me Zebra, which was it? Slave or test subject?"
	She stared at the flared cock-head right in front of her face. "I-I.... it was test subject... sir." she said meekly, looking up at him even as her tongue flicked out to play across his tip.
	Ace smiled a bit, deciding to play her into his hand. "Do you ever think of going back? Do you ever think of what they've turned you into, and figured a maybe a relapse would be best for a sensitive slut like you?" he asked. When she picked up her head to look at him he'd smirk. "Don't lie to me" and then take one of his big fingers and push it into her nose... DEEP, all the finger up her nose and his finger must have been at least as big round as a silver dollar at it's thickest. But when he pulled it back out there was nothing nasty connected to it, just tasty looking fem juice.
	She let out a shocked noise as he forced his finger up her nose. eyes crossing from the odd sensation ."Fnnff...ggg you did that to her?" she groaned softly. "I-I wanted to go back... but taking care of Poppy.... I couldn't"
	Ace smiled and sliding that juicy finger out his mouth. And he actually nodded. "I understand. That's actually very noble of you. However by tomorrow morning your daughter will legally be my property, physically and on paper, so you won't be her guardian anymore and you won't have to care for her" he said and cupped her chin in one hand and offered her his cock with the other. "I'm Dr. Ace Hoss and I work for Swits Inc. Give yourself to me and become my personal test subject" he said.
	 The zebra blushed hard, nodding. "I-.... yes sir." she said, hanging her head for a moment before latching on to his tip, tongue swirling around his tip, probing into his urethra every now and then.
	Ace murred at her suckling and pat her head. "From now on you're now Z-38. I'd tell you your rules but I'm sure you know them by now. The bedroom will make a better test area. Come with me, I've a powder for you to test" he said and walked up the stairs.
	She nodded. "What about Poppy?" she asked softly, a blush on her cheek as she followed him.
	Ace actually stopped at the stairs and looked down at the girl. "I'm actually not sure. She's to be my personal fuck toy, not so much test subject. I gave her one powder and she's already a Prime. (someone that's been modded to the point where the current mods effect their body on a massive scale an adding more would be unsafe or impractical and would need to be reversed before further modding) So On paper she'll be my slave. I suppose she'll be Z-06 on paper" (her age). he said then took a few more stairs before stopping and turning around. "Were you trying to avoid her turning out this way?" he asked, looking back at her.
	The zebra woman blushed. "I-I wanted her to be old enough to decide for herself." She said shyly.
	 Ace nodded. "Again, noble. However I can tell you were hoping she'd choose the same thing you did. But I chose for her, and took it a step further. I'm a scientist, I modded her and I claimed her. The rest of her days will be around my cock" he said then walked to the room with her behind him. Once there he poured the powder into a shot glass and handed it to her.
	 The Zebra nodded. biting her lower lip before hastily downing the powder, gulping it down quickly, a blush rising on her cheeks as she fell back into old habits.
	Ace nodded and took out his recorder and looked at his watch. [Subject Z-38 has taken the powder, effect should be soon] he said and kept watching the watch. Soon her groin got hot and her clit began to quickly turn into a cock and a big one at that. With each throb of her heart her clit shook and took shape, to thumbs and she had a dick head for a clit, two more and she had a four incher, at that same pace until she had a throbbing twelve inch between her legs, also in her mouth her tongue had turned into a four inch dick.
	: "MMppfff she mumbled, staring down as her clit grew and swelled outward into a cock, her legs twitching and her mouth hanging wide open as her tongue developed and changed.
[12:49:27 AM] Sky: Ace looked down and seemed a bit perplexed. [Hmm, Subject Z-38 has grown a cock as expected, and to a length expected. However she hasn't grown testicles like planned] he said then noticed her slurped speech and held her chin. [And her tongue has become a phallus as well. An unforeseen side effect, will have to go to the drawing board again, but will first test and see if the fertility effect is present] he then put away the recorder and took out a potion and downed it. He layed her on the bed before straddling her. "Z-38 I must see if you have fertile sperm as intended. Please cum as much into me as you can" he said before sitting himself down on her cock.
	 She gasped as he did that, grunting as her sensitive new shaft twitched and throbbed .With a groan she started thrusting upward into his rear, her sensitive new equipment only taking a few minutes to cum hard into his ass.
	 Ace grunted over and over, bouncing on her hips before she came, feeling her cum a good amount into him. [Mmph, after taking a fertility potion I've allowed Z-38 to attempt to conceive me, perhaps her testes are internal] he said before popping the cock out his ass. He then went downstairs and came back up, now having Z-06 back around his cock. He held a device, a tag applier, and put it to the milf's ear and clipped the tag to her ear, piercing it in another spot, in one smooth motion.
	 The zebra lay there panting for a bit, eyes glazed over a bit, until Ace came back. She raised up a bit, eyes going wide as he tagged her ear, a bit unsure about the familiar plastic marker in her ear, nearly identical to the one she'd worn for years.
	 Ace murred and grabbed Z-06 and started pumping her on his cock. "Mmm you may stay and live as normal, Z-38, but I come before your freedom (a cage with no bars, but still a cage) He then lined up his cock with her pussy as her cock began to shrink. "Ah good" he said and pulled out the recorder [Subject Z-38's penis is disappearing as planned.] he had intended the cock to be a temp means of being able to get someone pregnant. He then lined up his cock with the milf's pussy and shoved into her, with Z-06 still around his cock.
	The zebra howled out as her now normal cunt was suddenly stretched incredibly wide, not just with cock, but with her daughter wrapped around it. She moaned and whinnied, taking the shaft like an obedient lab slave.
	 Ace groaned loudly, feeling the momfs pussy through his fuck-toy's skin. "Fuck yes, you both belong to me now" he said, pumping back and forth. Inch time he shoved in the girl slid in some and each time he pulled out she slid out some.
