Lily sighed as she closed her door, turning the lock with a click . It wasn’t necessary, really; her roommates were going to a party, so she’d have the place to herself all night. But Lily also knew she was about to spend all night staring at pictures of girls in low-cut tops while wearing an ErosCorp shock collar, and that wasn’t the sort of thing you lived down if someone walked in on you. So, bedroom door locked, just in case. She had already stripped down to the optimal ‘spending all night on the computer’ outfit, which was to say she had discarded everything except her white cotton briefs and Cowboy Bebop t-shirt.

The rest of her clothes had been tossed haphazardly onto one of the many laundry piles in her room, which was as messy as usual. It wasn’t like she often brought girls back here. Lily swept her arm across her desk as she sat down, clearing clothes, half-empty model kit runners, and no small number of tissues onto the floor. She’d definitely need to clean this place up tomorrow; if Olivia agreed to be her Valentine after Lily asked with clear, confident eye contact, maybe they’d come back here after going on a date together, and Olivia would be all giggly and blushing because she’d had a really good time, and Lily would nuzzle into the taller goth girl, and maybe they could get into bed together… and the atmosphere would be totally ruined if Lily’s smelly cumstained tissues were scattered all over the place. She winced as she realised just how many of those there were; it wasn’t like she went out of her way to jerk off a lot, but for a lonely, inexperienced virgin like her, Jenna’s… unique brand of bullying certainly took its toll. Lily’s mind wandered, and for a second she thought about Jenna pressing her against the lockers earlier, and the time last week when she had spammed her with a bunch of selfies of herself in skimpy outfits the night before an important test, or the time before that, when Jenna had stealthily slipped off her panties during class and put them in Lily’s open bag, then called her out in front of everyone…

Lily shifted awkwardly in her seat, and glanced sidelong at the panties, which sat on top of the pile of dirty clothes and cum-stained tissues on the desk. Jenna hadn’t asked for them back.

“Ew, no, why would I want those? You’ve probably done something disgusting to them, right? Just keep them, perv~”

Lily tried not to look at the thick, heavy stains she had left on the panties since then. It wasn’t her fault, right? Jenna had literally given them to her! Lily had every right to use them as a masturbation aide, drowning the too-sweet scent of Jenna’s perfume with thick, musky ropes of cum while staring at those selfies…

Shaking her head, Lily tried to snap out of it. She couldn’t be thinking about Jenna right now. Instead, she fired up her computer, and opened the ErosCorp Portal she had installed on her desktop. Lily drummed her fingers against her desk as the startup animation played, soft pinks and purples resolving into the ErosCorp logo, the company’s name in sleek cursive (and the ‘o’ in ‘Corp’ replaced by a heart, naturally) against the silhouette of a slender figure with angelic wings, which Lily assumed was meant to be Eros. It was surprisingly professional for a company with such a shady reputation; as Lily scrolled through the list of devices the portal supported to find her collar, she got three separate popups offering cash if she wanted to beta test any of their new products. She dismissed all of them, although she hesitated for a little longer than she would have liked to admit on the one for an ‘enhancement’ pill called ‘Gro-Me’. Lily glanced down between her own legs, and bit her lip. Her dick had always been a little… below average. Unfortunately, these days, even if she had mostly escaped the effects of her cum thinning out from HRT (in fact, if the stains on Jenna’s panties were anything to go by, it remained disgustingly thick), she had paid a toll of two inches for her small, sensitive tits, taking her down to a paltry three inches when hard.

Y-yeah, but it’s not like girls really care about that stuff… right…?

Finally, she dismissed the popup. The only reason she was even touching an ErosCorp product was because the market for mental conditioning was pretty niche. Lily had heard enough dodgy rumours about the company that she didn’t want to get any more involved than she had to. That was part of why she had turned the voltage in the collar way down; who knew how safe this thing was?

She clicked into the ‘Conditioner EC-06’ tab, selected her custom program, and heard a muffled chime from her bag as the collar connected to her computer. Lily pulled it out, her hands shaking a little. There was no sugarcoating it, she was really nervous about this. What if it hurt? What if something went wrong? And… what if it worked? Lily squirmed in her seat, just thinking about Olivia’s emerald-green eyes, her cool, glossy black lips parting, a soft ‘Yes~’ in her low, husky voice in response to Lily’s confession… maybe even leaning in, pressing those lips against her own-

Lily let out a horribly embarrassed little squeak, and put the collar on without a second thought, pressing the lock on the back until it clicked into place, her cheeks burning. It wasn’t too tight, but even the slight weight of the thing, the constant reminder that she was wearing it, made Lily nervous. Turning her attention back to her computer, she clicked through the voltage and safeword calibration impatiently. She had already set that up this morning, before she had brought the collar into college to show Helen.

Another popup.

<Please calibrate eye tracking. Ensure webcam is switched on and follow the instructions closely.>

Lily confirmed that everything was working, and then let out a delighted (and slightly pervy) gasp when the calibration image came up. She had already prepared a folder full of images for the program to use to train her. It would put them in a slideshow, shuffle them, and then display each image for twenty seconds. And the one that had come up first, for the calibration, just so happened to be of Olivia.

Leaning back in her bed, taking a selfie from high up, her dyed black hair pulled back into a messy ponytail that showed off her red highlights, Olivia was giving a cool smile to the camera… and giving a generous view of her cleavage, pushed up by a black corset and left exposed by the plunging neckline of her similarly coloured t-shirt. She had texted it to Lily a week ago, along with the message ‘Looking forward to our next study session, ‘teach’~’. When she had first gotten it, Lily had thought she was going to pass out. It had been even harder than usual to look Olivia in the eye the next day after spending most of the night jerking off to that selfie.

<Please look at the face/eye region.>

Lily tried to ignore the fact that just looking at this selfie was making her kinda hard, and looked at Olivia’s gorgeous face for five slow beeps.

<Confirmed. Please look at the chest area.>

Yep, Lily could certainly do that. Her eyes flicked to Olivia’s tits, and she sucked in a breath. They weren’t as big as Jenna’s absurd D-cups, but they still looked like a nice, soft handful each. She’d lost count of how many times she had imagined burying her cute little cock between them, or drawing a breathy little whimper from Olivia by groping them and pinching her sensitive-

<Confirmed. System calibrated. Initiating program.>

Damn.

Lily shifted to get comfortable in her seat as the screen darkened, before fading into the first image randomly selected from her folder. Barbara Sachez, one of Lily’s favourite pornstars, leaned down, her tits practically spilling out of her latex bodysuit, her legs crossed to (almost) hide the bulge of her huge dick, and a cocky smirk on her-

“Aaaaaahh!!” Lily squealed as her collar buzzed, and a jolt ran through her body. She looked away from the screen, gasping for breath. Was this setting really only three out of ten? And had it really shocked her just because her gaze had lingered for a moment on Barbara’s tits…?

“This is going to be harder than I thought…” Lily muttered to herself. She looked back at the screen as the next image faded in, Barbara cupping her tits for the camera again, still smugly looking into the camera-

“Fffuck!!” Lily writhed in the chair as she was zapped again. What the heck? She had been looking up at her face the whole time! For a moment, she considered taking the collar off. This sucked, something was obviously broken… but then Olivia’s selfie came up on the slideshow again. Lily tanked yet another shock, whining and slumping in her chair. Unfortunately, she had to do this.

For the next few minutes, Lily endured zap after zap with every new slide. Slowly, she got used to it. Her attention wandered, and for a moment she remembered a conversation she’d had with Olivia a few weeks ago. She could not for the life of her remember how they had gotten onto the topic, but Olivia had mentioned trying out spanking with a previous partner. The taller girl had described how it was just painful enough to leave her body hypersensitive, more aware of every little part of herself… and Lily realised dimly that was what was happening to her. Her nipples were hard, scraping against the rough material of her t-shirt, her breathing was ragged, and her cock twitched with every shock. She knew her hair was all mussed up from the electrical charge and sweat. She must have looked like even more of a mess than usual right now.

The slideshow moved on again, and one of Jenna’s selfies came up. It was one of Lily’s favourites; she had propped her camera up, and had raised both hands above her head-

“Ngghaaa… what the fuuuuck…” whimpered Lily as another shock wracked her body. Seriously, she hadn’t even glanced downward that time, and the collar didn’t seem to be giving her any rewards, just constant punishments!

Wait a second…

Lily, shaky and frazzled, looked back up at Jenna’s face- and writhed as she was zapped again! Something was definitely wrong with this thing. Had the zones gotten swapped around by accident?

Huh.

So, if she stared at Jenna’s tits-

“ Oooohhgghhh… ” Lily moaned as a wave of pleasure rushed over her body, the same kind of shock as the punishment settings, but fast and hot and so fucking good , her body was primed by the hypersensitivity of all the jolts to feel as if she was melting, her embarrassing little erection twitching as it pumped warm, watery precum into her panties. Jenna’s tits were straining the material of her blouse, the tan skin just visible through the translucent white fabric, since she wasn’t wearing a bra, and fuck it felt good to stare…

Lily knew, distantly, that something was very wrong. She had to switch this program off, right now, before it was too late-

Another Barbara Sachez, this time shot from low down, so that she was leering down at the camera… in a top too short to cover the underside of her tits. Lily’s eye drifted there immediately, and she shivered as pure pleasure raced down her spine, most of her body going limp as her erection continued to splatter precum in her panties. Weakly, Lily tried to reach up to the back of her collar, to press the small button that undid the catch, but her hands were too shaky, and the image was changing again-

“Ngghh… p-please… n-no more…” Lily whined, her body spasming as she clawed uselessly at her collar and another pulse of pleasure washed over her while she leered shamelessly at another models’ tits, crammed into an undersized pink cheer uniform. Her head was getting so foggy… it just felt so good to stare…

Fuck. She needed to take this thing off, but her whole body felt like jelly, she couldn’t even turn her head away from the screen anymore… the safeword!

Another of Olivia’s selfies cycled in, one the goth girl had snapped surreptitiously in class. She was resting her chin on her hand, and looked bored (not that Lily was looking at her face). Her tits were resting on her desk, gently squished… Lily took a shaky breath, her eyes unfocusing as she realised she was dangerously close to cumming in her panties, hands-free…

“Olivia…” she sighed, dreamily, waiting for her collar to pop off with a click.

Nothing happened.

“O-Olivia…?”

She glanced up at Olivia’s face, and squealed as the collar gave her another vicious shock.

Was she being too quiet? Was something wrong with the mic? Had something gotten broken? Or…

Lily’s eyes widened, as the slideshow brought up another picture of Jenna, one sent from the gym just after a workout, a sheen of sweat visible in the tanned valley of her tits… and a mischievous glint in her eye. Lily gasped, writhing as twin bolts of pain and pleasure washed over her from looking at both parts of her bully… who Lily was realising, far too late, was responsible for all of this. She didn’t know how, and she didn’t know why (actually, maybe she could guess why), but somehow Jenna had fucked with the collar’s calibration!

“Y-you… bitch …” Lily gasped. Jenna’s picture didn’t reply. Lily was starting to panic now. This wasn’t just a glitch, it was a trap, and she couldn’t see any way out.

Couldn’t see…

“That’s it!”

Lily squeezed her eyes shut, and let out a shaky sigh of relief. OK. This was workable. She just had to catch her breath for a minute or two, and then she’d be able to unlock the collar manually, or even just get away from the screen entirely. As long as she just relaxed, and…

“Mmff…” Lily grunted. There was one part of her that definitely wasn’t relaxed; it was straining against her panties, and still leaking an embarrassing amount of precum. Having her eyes closed wasn’t helping; all she could think about was tits, jiggly and squishy and pushed up to the camera for Lily to stare at, so much easier to look at than girls’ faces; eye contact was so nerve-wracking and scary, but boobs were inviting and soft, and…

Lily gasped, her hips bucking. Looking at tits felt good. Slowly, she started tapping her left foot restlessly. Looking at tits felt good… and it had never felt better than when the collar had given her those surges of pleasure… maybe… she had recovered enough now? Lily could open her eyes, sneak one last peek before she popped off the collar. It wasn’t like she’d ever get to enjoy this combo again after she fixed the program Jenna had fucked with…

Jenna’s eyes snapped open… and she let out a furious, pathetic, impotent squeal of rage as she realised the image hadn’t even changed yet. Jenna continued to smugly jiggle her breasts into the camera, because Lily had been so weak-willed that she’d broken within twenty seconds, all to leer at her chest-

“Y-you… f-fucking… whore …” Lily gasped, shivering as another wave of pleasure hit her. The image finally faded out, and it was another Jenna selfie, this time with her boobs squeezed into a leopard print bra, and Lily didn’t stop herself, staring shamelessly at them… and moving a shaky hand between her legs.

“Y-y-you spend all your time b-bullying and blueballing me… ngghh… m-making me feel like a gross pervert…” she pulled her panties aside with her thumb, and moaned as she grabbed her cock, the excessive precum acting as the perfect lube.

“A-and you won’t even let me try to get a girlfriendddd… you j-just want me paying attention to you … w-well, I’m looking now!! I-I deserve to use you as jerkmeat, y-you fucking bimbo…” some distant part of Lily was shocked with herself. Even at her most pissed off, she’d never thought about Jenna this way… but she couldn’t deny it felt good. To finally give in and look at what that slut was always shaking in her face, and then teasing her for looking at… in a matter of seconds Lily’s room was filled with the familiar, rhythmic fap, fap, fap of the shy girl working her tiny cock, grunting and rutting into her hand as the picture changed, and this time she didn’t even try to look at Barbara Sachez’ face, panting and drooling as she watched the pornstar push her own cock between her oversized, plastic tits. The image shifted again. Lily deserved this, she deserved to feel good, if girls were gonna push their boobs in her face like this then why shouldn’t she…

Lily gasped as the latest wave of pleasure receded… and realised that for the past few moments she had been jerking off while staring at Olivia’s tits. She had gotten so carried away that she was treating her beloved crush like jerkmeat… she had to stop, the conditioning was already-

“Ngghhaaa!!” Lily squealed. She’d taken her eyes off Olivia’s chest and glanced up at her face, and the painful shock had put her eyes right back where they belonged… and a fresh surge of pleasure made her entire body go rigid as Lily’s eyes crossed, and she splattered a hot, sticky load over the underside of her desk!

She sighed, finally slumping back into her chair, her treacherous dick softening a little as it drooled excess cum all over her chair. The fog in her brain started to clear a little… before another image popped up in the slideshow.

“Nnhoo… c-come onnn…” Lily whimpered, as the surge of pleasure left her writhing and drooling… and completely hard again. She pawed weakly at the collar, but it was useless. As another image popped up, Lily’s resistance completely collapsed… as one hand slipped between her legs, and her eyes became glued to every pair of soft, jiggly tits that flashed up on screen, and hour after hour, the collar rewarded her for being so good…~

***

Lily wasn’t sure when the collar burned out. Sometime before her roommates stumbled back in from their party, at least. Lily slumped at her desk, listening to them drunkenly mooch around the common area before they all retired to their rooms. Finally, she lifted her leaden arms, and released the catch on the back of the collar. It slipped from her neck and fell into the junk pile beneath her desk, right next to Jenna’s panties. Stretching, Lily got to her feet… at the same time as her alarm beeped. Her eye twitched. She was exhausted, and frazzled, and still fucking horny . There was no way she could go into college today. What she needed to do was collapse into bed, and pass out. She would just get pissed off if she stayed up, grabbed her phone, connected it to the collar, and checked what exactly had gone wrong-

“Oh, you cunt… ” Lily muttered. It was exactly as she’d suspected. Jenna had jacked the voltage for the collar up as high as it would go, swapped the punishment and reward settings around, and…

“You’re mine , loser~”

Fucked with the safeword. Even used it to leave her a little message.

Lily was shaking again, with anger this time. She wasn’t going to let Jenna get away with this. She yanked on some trousers, pocketed the collar (she was so pissed she didn’t notice it had gotten tangled with Jenna’s panties, and accidentally pocketed those too) and stormed out of her room, too angry to think about the conditioning, or even confessing to Olivia… and trying to ignore the fact that she was still hard.
