Virid’s First Lab Experiment
 
Virid signed up for their liability waiver, and pushed it back over the counter toward the receptionist. He placed both hands back into the pockets of his dark green hoodie and took a seat to wait. This was his initial consultation, preparation for extra experiments in the future. Growth data for grass type Pokemon were severely lacking around this lab apparently, and that was all the invitation Virid needed to try his luck.
 
GroLabs was famous around this area for their size-based science. The Ivysaur had fantasized about visiting this place for several weeks, but hadn’t found the time to make a visit. This weekend though, he’d kept completely free to try out being a test subject. Virid was a little worried about the looseness of his clothes; the shorts and black t-shirt were likely to rip if he got too much larger. He made sure to bring clothes he wouldn’t mind getting destroyed for that exact reason.
 
Soon after returning the paperwork, the building began to shake rhythmically. A Dewott, taller than any Virid had seen before, approached the front desk. The quaking was from his careless stepping. 12 feet tall meant this guy’s presence was always telegraphed long before he arrived at reception. He picked up the clipboard, squinting at the tiny writing before giving a big smile down to Virid.
 
“Virid? I’m Alkali, I’ll be helping you with today’s initial consultation. Please follow me for your growth analysis.”
 
The Dewott led Virid through winding hallways and past many, many labs. This place was more of a maze than he’d expected; how did anyone find their way around this place? It smelled like incense in one hallway, poffins in another, and there was the sound of heavy machinery and metallic clangs behind one door they passed. This place was chaotic to say the least. Finally though they reached a room labeled ‘Alkali’s Lab’.
 
“Please follow me, and leave your clothing in the changing room by the front door.”
 
“Huh? My clothes? Why…?”
 
Alkali paused as he opened the door, then laughed patting the Ivysaur’s shoulder. “Oh right! Your first time here. Well, this particular experiment won’t have clothes that grow along with you. If you wear those, you’ll probably destroy them.”
 
“Oh but, I wore old clothes just in case-”
 
“You were thinking ahead? Nice, but trust me, if you’re coming back here again you’ll want to leave an extra pair. Just in case,” Alkali said with a wink. “Take it off, and leave the extra set of clothes behind regardless.”
 
Well, that made more sense now. He stepped aside and dropped clothes off in a changing room. This wasn’t the time to be getting embarrassed; there would be much more in depth experimenting and testing later if the rumors about this place proved true. Stepping inside the lab he saw that this place was sized up for Alkali’s entry and furniture, but lots of the equipment in here wasn’t necessarily scaled up entirely. Wouldn’t that make experiments much harder to do?
 
“Okay, please step over here…” Alkali said, as he picked up a tiny armband and helped Virid slide it on. The Ivysaur was still intimidated by the size difference between them, but he had to keep his hands over his exposed crotch to not expose the other feeling he had right now: being turned on.
 
“Oh, I’ll need you to keep your arms out to the side, it’ll be difficult to get an accurate body scan if you’re covering up like that,” Alkali said, turning dials and flipping switches behind a machine console. Virid was going to ask for an explanation but there wasn’t time apparently. A beam of lights flashed at him, creating a grid of lasers across the Ivysaur’s body. Surprised by the change he held his arms out at his sides, allowing the grid to scan him from the front, then the sides, and back.
 
Within seconds a wireframe version of his body was being displayed on a screen with statistics displayed like ‘strength’ and ‘growth potential’. It looked just like him, except that it also had several different heights available. One showed him standing next to a car, then next to a building, finally a mountain, with percentage probabilities and complicated calculations nearby highlighting the chance of reaching that size.

“So how does this work anyway?” Virid asked, rubbing his arms and legs down to make sure nothing was hurt or burning from having lasers shot at him.

“Well first we’re going to take measurements and estimate how large you could get. But that’s just an estimate so it takes some actual application of growth tech to get a more accurate reading. It’s mostly just some science magic. It looks like you have some great potential, a high chance to get to macro sizes with some help,” Alkali answered with a thumbs up. Virid wasn’t sure about that ‘it’s science magic’ explanation, but he didn’t feel confident enough to ask for details.

“Just hold on, I need to do some calculations before we actually move on to planning your follow-up meetings and first growth ray application.”

While Alkali rambled about the details of this growth ray, and how the data would be used for optimizing growth in Grass types, Virid was more distracted by the bowl of poffins at the Dewott’s desk. They looked very tasty, and he hadn’t grabbed breakfast before coming in this morning. He subtly used Vine Whip to let a vine from his back sneak over to snatch a poffin, checking for how much attention Alkali paid. And when Alkali didn’t notice the Ivysaur slowly increased his frequency. His vine kept snaking back and forth to the bowl.

Each poffin that Virid ate filled his mouth with sweet flavors, and made the waiting for Alkali’s rambling to complete easier to stomach. Orange flavored, pineapple flavored, strawberry flavored, and all of them sweetened with too much sugar. Virid was spacing out as he munched, not noticing how Alkali was preparing the growth ray behind a large, complicated looking console.

“Just to reiterate, please hold your arms out and stand still. Hold that position,” Alkali said, drawing Virid’s attention back. The distraction of his snacks ended, Virid put his arms out in a t-pose and stood straight to attention. Alky slammed on a large, green button labeled ‘Grow’ and followed up by a second, white button labeled ‘Start Milker.’ Four robotic arms with grabbing claws at the end stretched out of the wall behind Virid and each grabbed one of his limbs. It held him in place while the growth ray warmed up and fired into his chest.

“Alkali, what’s going on? I thought you would just take a leaf sample,” Virid asked, struggling against the restraints but not all out panicking yet.

“Leaves and pollen are fine as samples. They can work. But if you want the best samples, with the most information, you need something more direct. Cum works best,” the scientist said, his eyes gleaming with devious intent. Virid gulped as his face flushed a bright red.

The arms stretched Virid’s limbs apart from him and lifted him off the ground, pulled toward a wall spread-eagle. He wanted to struggle and get away, but there was an additional problem peeking out at his hips. He wouldn’t be able to hide the way his dick was getting hard from Alkali, especially since the scientist was purposely trying to get him horny. This was all part of the experiment after all.

Alkali rolled up the sleeves of his lab coat and stroked both hands along Virid’s shaft. It throbbed and Virid relaxed. His dick was now as long as Alkali's arm, and much thicker as well. Drops of precum dripped out and down the length of his meat.

Now that Virid was fully hard, he could move to the milking portion of the experiment. The flexible rubber of a flashlight snaked out of the walls and was guided into place on Virid's cock by cautious scientist ‘wott hands. The toy has a hose at one end, and thick enough around to fit Virid with room to grow.

“Come on buddy. Just let it out, this milking machine is efficient,” Alky said, licking along Virid's length. “Grow, I want to see you BIGGER~”

The Ivysaur's body tensed and growth spurts came in unison with his dick's cum. The floor and walls began to crack beneath his weight, but the machines did their work. He kept humping into the milker. Once it was all done Virid still had a few shots of cum left to shoot across his chest and hands. He leaned his back against the wall, catching his breath and cleaning up. There wasn’t anything immediately obvious to use, until the scientist pushed a button on the wall labeled ‘Towels’. A wall panel opened to reveal a set of different sized towels, anything from thumb sized all the way up to a parachute. That would’ve been impressive if he wasn’t already familiar with the sort of size-based shenanigans that GroLabs got up to in rumors. He picked a huge towel, but Virid wasn’t yet to the size of needing an entire parachute for cleanup yet.

His stomach grumbled when he stood to clean up. “Huh? Wha-”

Another growth spurt pushed him 5 feet taller suddenly. Moments ago he was able to stand up straight, but with that last extra amount of growth his head was brushing the ceiling of the room. How did that happen though? Virid looked at the growth ray and, yup it was still deactivated for now. That moment of looking was enough time for his tummy to gurgle again, threatening even more growth.

Alkali had his hand on his chin, trying to size up the situation. “What are you doing? …oh, you got into the poffins. Well, I suppose we can also test the interaction between growth ray and poffins,” Alkali said, adjusting some knobs once more. The Dewott had a devious glint in his eyes, as if this was just another variable to add into the growth rather than a problem. The hands re-emerged from their storage units, ready to grab the Ivysaur’s arms and hold him down once again.

Virid tried to take a step backward to get a better look at what was happening and avoid being trapped, but his foot bumped against a lab bench, so he tried to overcorrect and stumbled into the growth ray in front instead. There was no easy way for him to move without also bumping into or destroying other parts of the lab.

With that stopping him, it was little effort for the mechanical hands to hold down his limbs once more. The restraints on his limbs were capable of keeping up with Virid’s growth well enough; Alkali had designed them specifically to not get in the way of growth. The surprise of being trapped once again was enough to get the flower on Virid’s back to start opening up. It looked like how a Venusaur’s flower would open up after evolution, and the movement released a sparkling, slightly-yellow tinted cloud of powder. Sweet Scent filled the laboratory. Alkali relaxed the instant he smelled it his muscles relaxed, turning on more buttons for the milking machine. As he did the scientist started wondering aloud to himself. “Hm, interesting, I guess grass types are less reactive to electricity-based growth but more affected by the growth poffins. Maybe Pokemon typing has an effect here. Might be the way this ray is set up- OOF.”

Vines grabbed the Dewott around the waist and lifted him off the ground, connected to the flower on Virid’s back. Alkali completely ignored the fact that some grass-types didn’t need their arms to reach what they wanted in his distraction from the scent and thinking of experiments. Virid was very willing to remind him of it though. His dick was throbbing again, refractory period after getting off the first time apparently forgotten. 

“Mmmmhh. Give me MORE, Alkali!” Virid groaned as he used the vine to rub an otter across his manhood.

Maybe the increased endurance for sex had something to do with the sweet scent, or just the mixture of growth sources from growth ray and poffins. Alkali would need to test this out more to figure out how the different parts interacted. Repeatedly. Horny science needed lots of repetitions too. As Virid’s moans got louder, and the rubbing on his dick more forceful, Alkali knew his test subject wouldn’t mind at all. The Ivysaur was letting the more dominant and forceful side out now that he’d been kept pent up, and that was a whole other thing Alkali wanted to see more of too.
