"Good boy." a new voice said, revealing a man holding Todd's device. "I'm Jack, but you can call me Master. You're our new toy Todd, and you'll tell us how to do whatever we want."
Jack was a pretty nondescript blonde guy, about 5'9'' and a little portly at about 180lbs, looking smug. He continued "Surprised those two were up for it when I turned them back, but they want to show you how fun it is to have a new body. C'mere, boy."
Todd felt compelled to approach Jack and wait near him passively, allowing Jack to put a leashed collar on him as the monologue continued. "See, for a guy with a reality warping remote you've got pretty lax ethics. Unlucky for you, so do we. You're gonna be our little pet genius helping us come up with the fuckiest fetish scenarios we want. And you'll get to learn by experience."
Jack pulled Todd along by his collar gratuitously, device in the other hand. Jim was still blowing Rich, but pulled away to lift his shirt and expose his throbbing recordsetter with a smile as Todd was pushed down to kneeling level. The contrast between huge and small was almost hilarious as the larger boner almost poked Todd in the face.
"See, Master Rich loves big sub small top and Jimmy loves all ends of the jock-nerd spectrums." Jack continued expositing. "And I love narrating, even though right now it's just us four who recognize fuckery's afoot. Might use this miracle here to really indulge myself with the stop time feature too, or cum through your dick to spare me any mess, whatever. But I'll just stand back and say troubling shit while you get fucked."
Jack handed Todd's leash to Rich and stepped back to sit on a nearby chair, device at the ready.
"Go on, lick your masterpieces." Rich ordered, Todd autonomously moving to slather micropenis and macropenis in turn.
For his part, Jim shuddered theatrically but didn't cum yet, and Rich didn't last too long before spraying down Todd's throat and ordering him to swallow it all.
"Take your clothes off, 'cept the leash, and let me see what we're working with." Rich said, forcing Todd to quickly disrobe and show off his average erection (with a little inconvenience getting the shirt under the collar). "Huh. Kinda boring. Jack, you mind?"
"On it, boss." Jack started, about to drag a particular handful of sliders. "Todd, we're gonna bulk you up and slim you down, see how you look changing numbers before colors. You left all the instructions for that crystal clear and I read all of it anyway."
Todd felt...almost nothing, just a shift of air as what was true became realigned and his perspective scrolled. Certainly he was aware of the changes, but the act of changing was a succession of suddenly being different. Rich and Jim suppressed giggles at watching him cartoonishly jolt up and down and his dick piston in and out as Jack intentionally gave him less respite than someone screwing around in a character creator. Really, Todd's leash shaking from uncancelled momentum was probably a bigger tell. Todd was tall, then he was small, then he felt a draft, then a throbbing rod, then ridiculous muscled bodybuilder physique. Then he became a buff short king, then a lanky show-off, then a chubby bear of a man, and a few other random configurations before snapping back to original layout with somehow a lot more abruptness than the various expansions and shrinkings along the way. He was rock hard all the while, and maybe a bit harder after all the realignments. Jack made a pelvic thrust, seemingly as a joke, and Todd's dick twitched, probably still subject to whatever effect had been commanded.
With a smirk, Jack deigned fit to explain the motive for the sliding. "See, our sudden little polycule here could use a service top or a powerbottom, and we'll shift you around and us around whenever we like. Jimmy here oh-so-graciously said you should pick how you look first for your inaugural serious fucking, so tell him thanks and give us an idea."
"Thanks Jimmy," Todd started robotically.
