"...and that's why star-rank dragons are marble collectors, it's a big history." an entering nerd said to his gaming group. Glancing toward the shelves you were hiding behind, he casually added "Hey Terry."
"Hey Sai." you say, shuffling about books on pretense. "Back room's open full time if you want it."
"We'll camp out in there, don't worry." he joked back.
Sai Magna was a chubby, black-haired, blue-eyed, racially ambiguous maybe-white-asian-mix-you-weren't-really-sure nerd who ran some of the local adult nerdery. He was apparently a 'literal tech wizard', offering consultation work and a new paradigm that allowed many previously mysticist doctrines to be rendered reliable, under a cover business of regular miscellaneous tech work and technical writing aided by technopathy. Not very powerful, but he didn't need to be when hardlight and lightning handled the physics and esoterica would rather fuck him than fuck him up. Really, really liked being touched. To the point you were pretty sure your employer felt him up sometimes, and he even wore a vibrator in public if he felt like it.
Dude brought three other guys with him. Lanky redhead Gerald (classic nerd outfit minus glasses), muscular squarish-faced shortstack Tommy (baseball cap, tank top, and shorts? Really gonna hide that buzz brunet, sure), and Jules (tall, blonde, and fuzzy).
You let them pass untouched (for now) but have ideas. Sai won't mind a little more-than-friendly touching or you 'convincing' his friends to go way too far instead (frankly he'd like that), but you don't want to disrupt the game or do anything he can't play off as being in the moment imagined. As a personal challenge, mostly. Walking off to somewhere concealed then becoming invisible, you intend to possess each man's underwear in turn as they're seated around the table and getting miniatures set up. It's to get a feel for what you're working with physically. Your physical form fades away as you adopt a ghost-body, and vaguely segue into physical matter to adopt it as a temporarily motile shell. Passing into the cozy wood-paneled gaming room, you contemplate.
First off, you sneak into Sai's boxers to give his rock-hard 3-and-a-half-incher a few courtesy rubs so he knows you're here, meriting a pelvic thrust as you clench around him and undulate, patting his upper thighs as he's very much enjoying this. Yeah, yeah, go ahead and fuck with 'em, he signals mentally. Does he bring them here for the atmosphere, or the occasional thrill of a magic library and librarian sexually harassing them? Meh, you're still gonna do it.
Gerald's briefs, contents average. Tommy's jock is packed by a showy one alright. Jules is probably a grower at your best guess, though you only nudge him a bit. You alternate between the guys' pants and underwear, giving unobtrusive light touches whenever they adjust themselves until all four are at full mast. Your assumptions play out.
Sai sets out the campaign, some scifi-fantasy hybrid involving summoned creatures and whatnot, and so on the players play. Sai's nature is synergetic enough that you find yourself ironically drawn into his control as much as your energy would attempt to control him. Directing him is certainly possible, but his magic caresses your own in an almost as blatantly sexual way as you've possessed his underwear, and you might slip into his goals for a time if you try. You might encourage some 'method acting', but if you do anything too blatant you'll be noticed. Of course, slipping into Sai's role would certainly make 'awareness of control' more muted as it's played off by the game. Simon Says with a ghost, maybe? Certainly funky.
You notice he's touching your thoughts. Not pressuring or even guiding, but merely letting his presence grow intoxicatingly close to the point you begin to gravitate into a wizardly well. Formidable, alright. But he's busy playing a game and making sure you know it. You could learn from him, play it off as some 'jokes' or 'being convinced to like something by the game'...
How will you take control? So many choices. You touch all four men, and need only whisper (or write some DM notes with Sai's body) to make your will manifest. Restraint is like edging...but you're not much for denying yourself indefinitely.
"Feel free to let yourselves relax," Sai starts, prompting you to echo him just quietly enough to be heard. "it's fine if it's hot in here, adjust yourselves all you need."
While he was ostensibly referring to temperature and seating comfort, you and he both really meant sexually, and that's the interpretation in use by mind control. Almost immediately, hands slide below table into pants (only their own, for now), and a faint sense of being compelled counters itself through explicit permission. An order that liberates can sometimes be far more insidious than simply willing it so, important when lasting manipulation requires efforts you cannot immediately obviate.
Well, restraints are weakened. Time to have a gay old time...
