Sitting in the computer chair, Mike's tail flicked to and fro as he looked through the Chronivac's program. "Well, would you look at that..." He smiled, scrolling down the list of options. "You wanna be a big guy, like your old man, cub? I think we can do that..." Opening Jeff's profile, Mike turns Jeff's age up to 21. Watching the lion on screen grow, mane sprouting and muscles developing, Mike smiles. "Not bad. But if you wanna keep up with me, we'll have to - ah!" With a few keystrokes, he'd started altering Jeff's stats and the lion on screen responsed. His balls swelled, the furred sack bulging as they grew and bloated, producing more and more lion testosterone. The lion on screen bulks up - pecs swelling into spheres of brawn, arms bulging with new muscles, arse firming up. Hair sprouts in, too, and the soft lion cock between Jeff's legs engorges with more and more meat.
"Not bad," Mike chuckles, lazily running a paw over his own hardening dick. "But I need a proper muscled son to keep up with me..." Already he's oozing pre again, his overactive nuts feeling full. Click, click, click...
Now the model on screen is a hulking brute of a lion, almost as big as Mike. Big, meaty pecs, capped with thick chewable nipples crown the new Jeff's chest. His arms are thick and muscular, biceps and triceps fighting for space. Atop a neck thicker than some men's thighs sits a proud lion's head with a regal mane. Speaking of thighs, the dick and balls between the new Jeff's are almost obscene; a thick, fat piece of alpha dick and a pair of balls the size of oranges to keep it fueled.
Mike lets out a soft growl, watching his son take on new and exciting shapes on the screen. His mouse hovers over the "APPLY" button... except...
"I love you, bud, but this is MY pride," Mike ponders. Two grown lions in this little space? No way. Biting his lip, Mike hits 'SAVE DRAFT'. His eyes find themselves dragged to the hulking lion on screen again, and he lets out a frustrated mewl, his dick throbbing.
In order to distract himself, he flicks through the program, and lets out a whistle. The options don't just list changes for people - he can change the environment, too. Right-clicking the bed in the 3D model of the room, he select the sheets and then "Material".
"Oh wow..." Color, texture, size - A word catches his eye, and with a grin, Mike clicks "Rubber" and hits "APPLY". Looking over his shoulder he sees the color bleed out of the bedsheets - they're turning black and shiny. Under the covers Jeff squirms, but just turns around.
Mike grins. And turns back to the keyboard. Opening a side menu with preset-items, he scrolls down through the collections - and finds what he's looking for. "Gym Equipment. Just what I need for this beautiful body." A weight rack. Benches. High mirrors... Everything fizzles into the room by the power of the chronivac. Then Mike sees something in the list of items that makes his dick jump, a shot of precum splattering into his pecs. "A sling..."
He can't resist. He can see it - his son, all grown up, big and beefy, lying in the sling and mewling for his daddy. Mike bites his lips. "I just need to keep him under control somehow... show him who's the alpha here..." Something catches his eye on his own profile.
"Musk potency?"
He looks at the option. "A measure of the potency of your scent, it's ability to attract and impress mates..."
Mike's face splits into a predatory grin. "Just what the doctor ordered." He clicks the slider and drags it from four to five... no, six... nine... Fuck it.
Mike sets the slider to ten, and before he can change his mind, he hits "APPLY".
