Will he keep messing with her or move on?
He Has Just a Touch More Fun
[Author's Note: Hello! This is my branch off from the main branch; you can go back and choose the first option in the list to see the canon path set out by the story author, duduvar. As such, some events will play out close to or exactly how they did in the main branch (i.e. the introduction of "Jane," the behavioral punishment options), while other choices will diverge rather significantly. I hope you enjoy!]
... At least, I'm set on letting her go easy.
The problem now is that the fun I have with her is limited to just English class! Not satisfied with that, I open the app to consider other "subjects" around me as the classes press on. I've only got one gem left until midnight, so for now it's mostly a scouting mission. The girls in my classes run the gamut in terms of looks and bodies, but now I have my veritable pick of the litter. None of my teachers are as tempting as Ms. Lia, though, and having more than one of my teachers acting out might cause problems. So I spend most of the classes browsing the girls. I end up narrowing my candidates down to girls who I've seen around my neighborhood:
First, there's Donna Chen in my History class. Her family's got money and she's got mostly AP classes, but beyond that I don't know much about the math genius and Chess Club president (the "Queen" they call her, to hear it from Neville). She's barely got A-cups and she's skinny besides; petite, flat black hair, and thick-rimmed black glasses make sure she's never talked about in any horny or fashionable way... probably just the way she likes it. There were bustier girls in the classroom, sure, but Donna has an unapproachable air that made her name on the app way too interesting.
Then there's the star of my Math class: Sarah Santiago... or as the app calls her, Sara de los Santos Santiago-Fernandez, one of the few other 19-year-olds in my classes and a cheerleader to boot. Our school has its share of bitchy or infamous cheerleaders, but Sara is shockingly not one of them. She's also doing fairly well in class, so I can't even guess why she's a year older than most of the rest of my class. Not one inch of her seems bereft of a clean, golden tan, and she fills out her fashionable outfits with thick hips and a generous chest she hides until it's time to dance for the jocks. Ms. Lia deserves a bit of **** for all the shit she gives us... but Sarah? She's the crown jewel girlfriend of Richard "Big Dick" Richards, the biggest gorilla on the football team and son of some oil rig mogul. She'd be one Hell of a prize to get if I could customize her my way... and out of Richard's arms.
But there's one more star on my radar, and she's flunking the Chemistry class we happen to share lab in: Leona Teller, our female basketball team leader and a tree of a woman. She's 6'3" and muscular, but she still manages to have a thunderously huge ass and tits she likes to keep tamped down with gym clothes underneath her uniform. The only reason she's not with anybody is probably because she intimidates the Hell out of the boys of our class; supposedly she used to beat kids up in middle school back in Atlanta before her parents moved out here. She doesn't have much patience, and she's violently direct when she disagrees, but seeing that amazonian bod shown off a bit more got me so bothered that I couldn't even listen to the rest of the day's lesson on molecules or whatever.
I don't even bother looking at their options yet; I've only got one gem to my name anyways. Better to mull it over, do some research online, and then make my choice...
"So you're in a good mood," my sister greets me as I climb into my car, "something special happen?"
I freeze up for a second. My thoughts had been buried so deep into perversion that I zoned out between the last bell and coming out to the parking lot. My sister is riding with me today, and I nearly panic until I remember that no one knows about the app or what I've done. I focus on that thought, glance back at her, and shrug with my perverted grin still on my face. "Just a good day..." A familiar face hastily walks towards her car in front of us before I pull out: Ms. Lia, still flustered and moist from earlier. "... and the first one where I haven't dreaded Ms. Lia's class."
"I bet: was she like that in class?! Her tits are just..." My sister's eyes go wide in the way they only ever do when some real knock-out knockers have crossed them.
We share a laugh that I cap off with a gentle jab, "What, you're going after my English teacher now?"
"Hell no! But I'm not complaining about a free show..."
I bring my phone out but carefully put it next to me and out of sight. With my sister's attention locked on the damp instructor, I quietly navigate to my commands and pose my finger over the drop button. Another moment, a fumble for her keys, and...
The keys almost seem to leap from her hands to the floor, earning a bubbling groan of anger from her chest. Nothing was going right today, and the frustration of it tormented her. She thought to pick it up after a careful glance around... and that's right as she caught sight of two utterly undesirable faces:
Mr. Haines, whose eyes were thankfully cast down at his phone or something else in his car...
... and Ms. Haines, the lesbian lech of the school and a rather pointed topic of critique among the more conservative teachers. She leered predictably at this predicament, and Ms. Lia swore that this time she'd-
... start bending at the waist, her ass pointed right at the ogling carpet-muncher, as she picked up her keys. That wretched little dyke would think Ms. Lia was flirting with her at this rate! But even as she rushes to get the keys to the door, her purse is next to magically drop from her grip, and down she goes again, her moist tits swooning into view even from behind the emphasized rump now begging to burst loose from her skirt.
"Fuck... if I didn't know any better, I'd say that bitch is trying to flirt with..." My sister's sigh was perhaps the horniest she had permitted herself to sound around me; a seed was planted, even if it was just a happy accident from my last bit of fun with Ms. Lia.
Well, last bit of fun today. Leaving my sister to stew in theories about what Ms. Lia was "trying" to communicate, I drive us home.
Later, At Home
My sister amped her music up loud enough to cover whatever she'd be up to, whether it was work or fantasizing about Ms. Lia. I'm having trouble accepting this whole thing is even real, but seeing her react to the same antics more or less seals the deal for me: this app has power... and I can make that power reach pretty far with even its simplest commands. I review them again even though Ms. Lia is now well out of range; the names of my sister and mother come up, along with the nearest neighbors who have women inside. Both were older than my mom and, unlike my blessed mother, showed it too well; but maybe with this app...
"Heh heh, looks like you’ve had some fun." The voice is silent yet loud like a suggestion from the groin. At first I think I imagined it... but its proximity, its dripping presence, startles me from my review of the app. I scan the room for an origin, but find none. It sounded too clear to be a speaker, much less a voice in my head, but where else...? "Silly, right here!" The voice is louder now, as full-bodied as the speaker who suddenly manifests in the middle of my bedroom.
My own body locks up in her presence; my pants immediately tighten. Gray, shimmering skin with claws and teeth and sex organs tattooed across its valleys cover the creature that has come to visit me. The tattoos go everywhere, and I know this because she is stark naked. Wide, breeding hips flank the narrowed gap where a dripping sex ever waits for a lover; breasts that surrender only barely to gravity to emphasize their heaviness sit and stare back at me over a taut, flat belly waiting to be filled. Her inhumanity comes not first at the gray skin or the blackened nipples, but at her face: long, elfin ears flank thick, blood-red lips and the curled horns that peak out from among her red bangs. Those crimson locks flow behind her and down to her butt, or at least would if they were not suspended in a many-tendriled aura around and behind her. She is... unnatural. She is not human. As insane as the app might've been, it had been only somewhat otherworldly in a century full of hypnosis, foreign agents of influence, and CIA decodings of mind control devices.
But this... this was a demon, and my silence and my throbbing dick are the only reactions I can pull out as my brain screams.
... but only for a few seconds.
She stands there, moist and grinning, until my mind finally bends and shapes well enough to accept her words. "Don’t worry, I’m just one of the developers!"
"D... Developers?"
"Yep! I'm just here to check in on our favorite customer!” Her voice is upbeat and sultry in some insane combination that works for no one but her. She would be an obnoxious salesman if it didn't sound so sincere, and for a moment I'm not sure she's not teasing me. “Well, our only customer, but that’s not really a necessary detail right now. You can put your penis away, now.”
I slowly look down... and realize I did literally pull my meat out as if to offer it. Panicking, I shove it back into my underwear as I stammer, “Wh-who are you...?!” It's all I can manage. She's the "developer," I repeat in my brain. It feels like maybe she's making fun of me... no, toying with me.
“I’m just one of the few working on that app... you know, Custom Girls? You can call me Jane... I mean, that'll be way easier than trying to teach you my real name, at least."
"The few...?"
"Ah, the few succubi."
A few still-moving cogs in my brain dredge up images associated with the term. "A... you're a... lust demon?"
"Jane" snorts at that. "Oh, you're just too cute." Alright, now she's definitely making fun of me. "But yeah! We succubi have been hard at work for centuries now, and while we're pretty good at our job... well, it's starting to get boring, you know? Believe me, even fucking can get old! So we did some thinking together, and we figured out a way to get energy not from fucking humans, but from having humans fuck with other humans!" The matter-of-fact sales pitch and American dream story tone she takes on drives me near the brink as I try to follow along. "Now I myself don't quite sure know how they got it to work; I mean, I'm a dev, but I mostly just worked on the UI aspects. But what I can tell you is that we made the app a bit... too good. Like ruin-society-forever-if-we-mass-distributed-it-on-the-market too good. So we're going with a small launch group... really small. Right now: just you!”
"How..." My spine finally slips back into my ass, though the metaphor makes me uncomfortable with the air getting as hot as it was between me and "Jane." I sit up straight and ignore my painfully erect cock as I try to speak with some authority, "So... how the hell does this work? Why are you in my room?”
“I can go wherever I please, thank you." Lust gave way to a threat, there, but she switches back in an instant. "... And I was just stopping by to say I was rather impressed with your little show at the school today."
"S... Show?"
"Yeah! I mean you pulled quite the number on 'Ms. Lia'; we were almost as surprised as she was when you exploited the commands that well! Plus the little show you put on using her to get your sister going... mmm, I can taste it on the air already... very nice. Collateral lust is big for what we're aiming to achieve with this app, and a dirty mind like yours is going to get some great results, I can tell!" I'm still unsure of how to take it all, so she adds, "That's me encouraging you, by the way."
"W-Whoa, whoa, are you... are you like, harvesting this... lust then, like from me... and my sister?!"
"Oh, no no no! It's not harvesting! I mean, at least not from people. It's more like... generating. Sexual relief gives us power, sure, but sexual tension... ah, it plumes into the air, fuels us, gives us all the gas we need to... well, keep going." She holds up a hand as if she was taking an oath. "I swear we’re not sucking out people’s souls or anything; that’s just a myth started by prudes. We live by spreading pleasure, and now we’re just asking you to help us spread that pleasure... and I can see we chose the right little man to do it.” She grinned and winked at me with something like praise. Or hunger. It's really hard to tell which with this being.
I process her words before glancing back down at the app. Either I'm having a total breakdown or... well, the app is explained. No secret government agent is going to come in and lock me up for my crimes or my role in experimentation; no hypnosis app generator is going to take me next; it's just... demons. I guess that makes the most sense, right? I try to reassure myself with that much... and try not to think about how demons are, rather suddenly, real. “Alright, I’ll just... keep up my plans I guess.”
“Oh, I can’t wait! If you need to talk to me, there’s a little question mark icon in the app. It’ll serve as a kind of lifeline in case you have any questions. So... good luck! I’ll be.... watching.” With that, she started fading into the air, leaving me alone in my room with the sound of Alice’s music through the wall.
So this is where I now stand: midnight is coming soon, and with it another ten gems... from Hell. I'm feeling weirdly calm about it, all things considered... but for now, why question my good luck? Ms. Lia was probably home struggling to say "breasts" without using a middle school euphemism, my sister's starting to get hot for teacher, and I've got three new girls to consider for my actions... or... I could keep focusing on Ms. Lia.
The thought of seeing how far I can take her excites me the more I think about it. Before I end up jerking the night away, I play some video games to pass the time as I wait for midnight to roll around... and slowly, painfully, the fated hour appears. I now have 11 gems... and too many options just ripe for the picking.
So who do I focus on? Ms. Lia? One of my classmates?
