Kuuvik taps his clipboard and peers inside.

Echoen peeks up at you and squeaks, another shot of thick white seed flinging from the oversized pink shaft thrust up from hir groin. Shi's only four inches tall, but the fact that shi's anthro - and hyperhermed - speaks volumes of the chemicals shi's been injected with. With one paw shi strokes hir shaft, the other kneads hir D-cup chest.

Kuuvik is abnormally tall to begin with, so four inches seems even smaller to him. Despite referring to himself as a he, the bug sported two gallon-sized breasts, bundled up in a sleeveless black shirt. Matching shorts kept his similarly sized crotch in check. In truth, the clipboard was a prop, he'd used it to sneak in, he wasn't supposed to be here. He had a thing for growing, and now he'd stumbled upon a possible catalyst. His big blue eyes scanned the chamber for a way to save you, though whether that was out of kindness or neccesity remained to be seen.

Echoen stares up at you with vivid green eyes, speaking of a budding intelligence but one that's consumed with the pleasures wracking hir growing frame. Shi had just been casually jacking off before you entered, but you had seen that shi was working hirself up more and more excited as you stood there, as if shi was lusting for you. Hir glass cage was actually a travel container, as if shi was a pet mouse. A green plastic roofing with vents. Arching hir back and *squeaking*, shi unloaded another thick jet of cum into the air, splattering on the glass, a huge volume for a girl so smalll, maybe about 1/2 a cup. Slumping back, shi panted and stroked hirself more, hir body bulging and growing, 5 inches tall. Hir balls quickly refilled and fattened *larger*, hir pink prick thickening as well, reaching about 3 inches. Both of hir paws groped hir breasts, tugging hir thick nipples, E-cup for sure.

Kuuvik 's antennae perked in anticipation. Whatever you had, he wanted some. Despite the small size of the container holding you, a formidable lock kept him from doing much. He fiddled with it for a few moments, as tinkering was a trait inherent to his species. Eventually he pried it open, reaching in and scooping you up in his claws. He tilted his head back a bit and closed one eye, as if anticipating an explosion, which, given what he'd seen of you so far, was probably a warranted reaction. He had already damaged the lab's entrance lock enough that nobody would be able to interfere, but he was cautious, unsure how much of a mess he could afford to get himself into. He didn't want to get caught, after all.

Echoen: By the time you claim hir, shi's a lot more energetic and there's a LOT more of hir. Shi easily reaches 8 inches tall, if not more, and shi has raised a pool of spunk within hir container about 1 inch high, most of it soaked into hir bedding. Shi stands when you pop the lock off, hir cock twitching between hir breasts, as shi's reached a very similar proportion to you. As shi's actually fully female, hir hips are a bit more padded and broader, with a bubbly ass and long thin pink tail. Hir pussy aches underneath hir, dribbling down hir legs. Squeaking happily and lifting hir paws up, shi clings to your hand as you scoop hir out, a mere brush across hir cock causing hir to ejaculate a full cup of spunk all over your arm. Hir squeaks are more like moans now, a nice mix between the two. You feel hir growing heavier in your hand, shuddering, staring up at you as shi swells to 10 inches in the span of a few long heartbeats.  Hir cock resting just under hir chin, drooling copiously. Shi massages hir breasts, as if displaying them to you. The way shi stares at you makes it a bit hard to break eye contact.

Kuuvik couldn't help but be surprised at the way your body changed, migrating from holding you with his palms to holding you in his arms as you grew. He pondered how exactly he might inherit this trait, as the seed on his arm seemed to have no effect. He clamped his mandibles over your cock and began to suck, a blue blush making its way to his cheeks. Worth a try.

Echoen arches hir back and *squeals* as your lush, holding your face with hir small soft paws, pumping hir prick hard into your mouth as the pleasure for hir is surely phenominal. Hir fat mouse nuts slosh and bump against your chin, and within seconds of your gulping at hir cock shi is cumming. Clamped and clutching to your face, shi pours hir hot thick spunk deep down into your throat, a cup and then another cup from hir 7 inch cock. The mouse squeaks - and creaks, hir body growing in a surge, pumping up bigger on your face. More cum pours down into your throat, as shi rapidly develops, 14 inches tall and surprisingly heavy, clogging your throat with hir cock and *gushing*. The first symptom of hir traits is the tingle within your genitles... and the erupting gyser of pre and cum that pours out from your shaft, as your balls hyperdrive in seconds.

Kuuvik moaned and shut his eyes tight, seeming insistent on not losing a drop of your seed. His repeated gulps were quite audible, and his arms shook a bit as he struggled to continue to hold you. He bent his knees inward a bit as his crotch ballooned outward, cock lengthening, thickening, and popping the button off his shorts, then unzipping them. His thong did its best to keep his swelling groin in a nice bundle, even as that bundle flopped out of his shorts and they fell to his ankles. His balls pulsed outward, swelling to his knees and beyond, but his thong seemed designed for this. It held strong, a wet spot forming where the clearly-visible tip of his shaft was, before he shuddered and let out a muffled moan, that wet spot growing much larger, soaking the majority of the fabric as excess seed spilled out from it and pooled onto the floor.

Echoen pumped rapidly larger, hitting 22 inches in just a few moments, with hir cock more than half that. Hir breasts swallowed most of your head, sloshing and gurgling with flesh, growth, milk. Hir legs wrap around your neck and hold tight, hir immense balls, cantaloups, resting on your strainging bustline. You feel your whole frame creaking, your world nudging smaller as you jump up two inches in height. The more you leak, the more you need to leak.

Kuuvik moaned deeply, lazily opening his eyes to check his surroundings, the increase in his already considerable height being something he could feel even when they were closed, slightly disorienting. Despite being only two inches, that height boost made his remaining clothing look that much smaller. Now that his hands were free, he reached up to squeeze at your easy-to-reach balls. He needed more...

Echoen: as the murine pumped up rapidly larger, she fucked your thorat with even more passion, three feet tall in a blur. Her nuts were hugely fat and full, despite the gallons she drainred into you. She was bent over your head, her breasts on the back of your head now, more as she grew. Her plump legs clutched the sides of your tits.

Kuuvik drank from you relentlessly, tilting his head up a bit. He placed his hands on his hips, moaning and drooling as his stomach finally started to show how much you were filling him with. He'd developed a nice potbelly, pushing his shirt and chest up slightly. A glob of blue honey emerged from the tip of his abdomen as it seemed to grow a few inches wider.
