Sabrina discovers the extent of the P.A.D.'s powers.

It was difficult focusing on the P.A.D.’s UI while attempting to return Nick’s passionate kisses; at least Sabrina was getting a hang of what to do with her mouth. She let his tongue slip between her lips so he could deepen the kiss, the rumbling noises of pleasure rising up from his chest mixing with her own soft mewls and breathy moans. All the while she still held his cock in her hand, rubbing her thumb along its softer underside. Nick had taken the initiative instead of waiting for her to figure out that she was supposed to be moving her hand, his hips moving in gentle, shallow thrusts to glide his dick between her fingers.

That dick was the current target of the P.A.D.’s display; Sabrina wasn’t good at gauging size, so when the options began to float by she settled on measurements that she had seen thrown around online without much regard for just how big it actually was. Maybe if she had considered that ‘FOOT LONG’ had been used to advertise sandwiches she would have hesitated, but it wasn’t until she got the ‘INPUT SELECTED’ alert that she realized what she had gotten herself into.

Nick’s cock lurched in her hand, her fingers **** apart by his steadily growing manhood. The veins that ran along his length bulged as blood surged into his expanding shaft, inches pouring out from the base until his swollen tip was pushing against her stomach once more. Her fingers couldn’t even wrap entirely around his girthier size anymore, a decent gap left between her middle finger and thumb. Sabrina pulled back from their kiss in shock, finally getting a look at the monster jutting lewdly between his legs.

“Holy shit!” She balked at his size, and how tiny it made her hand look as she tried her best to hold it aloft. Nick’s cock was so big that it was actually flagging a little under its own weight! Maybe she had gone a little overboard…

“I get that a lot,” Nick teased with a coy smirk on his face.

His shallow thrusts weren’t enough anymore, he had to put a little more oomph into his hips in order to run Sabrina’s hand along the entirety of his enhanced dick. From an aesthetic standpoint Sabrina was in awe, but from a practical standpoint she was a little intimidated by the behemoth that she had saddled him with. She wasn’t the only girl to have felt threatened by Nick’s cock; thanks to the retroactive changes to his anatomy Nick’s list of past sexual partners shortened, mostly due to his sheer size. While some women were thrilled or impressed at the foot-long fuckstick he kept stuffed into his boxers, a lot more were simply unable or unwilling to attempt to take such a huge cock inside of them. Sure, he got a lot of enjoyment with hands, lips, tongues, tits, and any other body part he could grind against, but Nick was spending a lot more time jerking himself off and a lot less buried inside of pretty girls.

It was a cock built for porn, but unfortunately he lived in the real world. Thankfully it lit up parts of Sabrina’s porn-addled brain, and her awkward gawking turned into a quiet laugh.

“Oh my God, I can’t even cover it up with both hands…” She tried her best, though this meant that she had to put the P.A.D. down on a nearby shelf, but not before giving Nick’s genitals another slight rework.

Sabrina had neglected his balls! They were a healthy size before, but now they were literally overshadowed by his new and improved cock. In the back of her mind she was worried that he might have trouble finding a pair of underwear that would fit him comfortably, but she wanted to perfectly round out what was shaping up to be a piece of art… at least to a pervert like herself. ‘PLUMP + TIGHT’ sounded perfect, and after the text flashed its usual ‘INPUT SELECTED’ Sabrina enjoyed the sight of Nick’s sack inflating before her eyes.

The loose skin began to grow taut as his nuts grew inside, each one pulsing out in diameter until they were the size of large plums, hefty and easily big enough to fill Sabrina’s palm. Now they looked far more appropriate underneath his porn star cock - the sparse pubes that he had before vanished, leaving him smooth to the touch, something that delighted the increasingly enthusiastic teen. With his new equipment and sexual appetite Nick was now the sort of guy to keep himself meticulously groomed, something that Sabrina appreciated as she began to explore below his belt with curious hands.

Nick tilted his head back and groaned; what she lacked in experience she was trying to make up for in other ways, and he seemed to be enjoying her clumsy touches. Finger tips traced over every throbbing inch, soft palms cupping his heavy sack, the occasional lazy stroke eliciting appreciative noises from the hung older boy. He was fun to play with, but a frustrated and lustful sigh slipped past his lips, and the roll in his hips grew a little more insistent.

“Try using your mouth,” he suggested, although his tone made it sound more like a demand than anything else.

Sabrina stared at his fat cockhead nervously. It looked nice, but there was no way she was going to be able to fit that thing in her mouth. Maybe she could kiss it, use her tongue a little, but it would be an awkward first experience with oral for the girl. She was starting to think that his size was impractical - fun, but impractical. If she wanted to actually enjoy what Nick had to offer, she would have to scale him down to something more reasonable and manageable for a girl like her. So Sabrina reached back for the P.A.D. and-

“Hey, focus Sabs,” Nick chuckled, reaching out and intercepting the device before she could grab it.

“W-Wait, hey, I need that!” Sabrina nearly shouted, the worry in her voice giving Nick pause as he stared down at her.

“Relax. You can live without your toy for a few minutes while you take care of this,” he said while he rocked his hips, swaying his weighty cock from side-to-side. “It’s only a- Huh. That’s weird.”

Sabrina felt her heart drop into her stomach while she watched her coworker stare at the featureless black rectangle. Whatever he saw, she couldn’t.

And whatever he was going to do, she couldn’t stop him.

Sabrina was trying to think of some way, any way, to get the P.A.D. out of Nick’s hands. Even though he didn’t seem like the type to do anything completely insane with it, she had already seen first hand how few safeguards it had to prevent accidental usage. She had a very horny boy’s thoughts to worry about, and Nick had no idea just how powerful that unassuming card he held really was.

“Whoa! This is neat, Sabs. I didn’t know you had a- what is this, like one of those digital picture frames?” Nick asked as he held the card closer to his face.

He was the only one who could see the floating green holo-Sabrina that was being projected, the P.A.D. immediately defaulting to the only available target.

“Something like that!” Sabrina quickly responded, **** to deflect his interest.

Both of her hands came to grip his thick shaft as best she could; it took a surprising amount of effort to pump his dick, the length of travel from base-to-tip requiring her to really move her arms, even with each hand working its own half. She was relieved when she heard the soft noises that Nick started making in response to her touch, hoping that he would lose interest in the P.A.D. and focus on the girl stroking his cock. He wanted her to use her mouth, right? Sabrina’s **** took a backseat; if the card was scanning his thoughts then she knew it was only a matter of time before it did something to her, and the truly worrying part was that she wouldn’t even be aware of it.

So the nerdy girl knelt down on the dirty tile floor in the backroom of the local Bean Roasters, leaned in, and pressed her thin lips hesitantly against Nick’s swollen cockhead. His entire dick throbbed and lurched, followed by a low groan and breathy chuckle as Sabrina began to clumsily kiss and lick around his tip. She doubted if she would be able to get much more than a few inches in her mouth; he had girth, and without the P.A.D. in her possession she wouldn’t be able to shrink him back down to a more manageable size. So instead she had to make due with what she could, hands still stroking whatever she couldn’t cover with her tongue. At least she was eliciting a reaction from Nick, who brought his free hand down to rest on her head and stroke her dark hair.

But it wasn’t enough.

He still held the P.A.D., and with his mind focusing on Sabrina’s amateur treatment of his dick the powerful device had plenty of direction to begin warping things around him. Nick caught the shift in the hologram out of the corner of his eye but mostly ignored it. With all the blood surging to his massive cock his thoughts were almost entirely railroaded towards the skinny teen kneeling in front of him, but the P.A.D. didn’t need his attention to carry out its function.

He was happy with Sabrina’s attempts at… well, he wouldn’t exactly call it a ‘blowjob’. She was mostly just running her tongue over his dick. Not that it felt bad, and Nick was used to disappointment when it came to his size, but he wished more women were able to take him down their throats. It was an unrealistic idea, but the envy he felt whenever he watched a deepthroating video during one of his laborious jerk off sessions - which were far more frequent now, thanks to Sabrina - was exactly the desire that the P.A.D. began to tap into.

‘ORAL SEX ABILITY’ popped up above holo-Sabrina’s head, then immediately selected ‘SEASONED EXPERT’ from the options. Nick’s attention swung back to the device just in time to read the words before it flashed ‘INPUT SELECTED’ and Sabrina’s history was quickly rewritten.

He noticed the change in her technique immediately, her licks becoming much more practiced and sensual, using the flat of her tongue to drag slowly along the tender underside of his oversized prick and then swirling around his sensitive head, before planting a wet kiss right at the tip. Nick shuddered, his confusion completely overshadowed by his rampant arousal.

“Mnh, I don’t get to play with ones this big too often,” Sabrina said wistfully as she tilted her head to nibble along his shaft.

“Nnhh… I didn’t think you’d done this before,” Nick breathed out.

“Sure, because I’m so innocent,” she said with a stifled laugh.

Was she wearing makeup? Sabrina had never worn makeup in the time they had been working together but she definitely had some subtle eyeliner and foundation on. Her eyelashes appeared fuller too, but Nick wasn’t yet privy to the fact that she wasn’t the same inexperienced girl that had been fumbling around his cock just a moment ago. This Sabrina had a lot fewer sexual hang-ups, the anxiety she was riddled with now replaced with an impressive résumé of dudes she had proudly gone down on. Dicks of all colors, shapes, and sizes had slipped past her lips at some point, her reputation as the school vacuum during her senior year well-earned. Sabrina was an industrious little cocksucker, the sheer volume of guys that she had sucked off lending credence to the fact that practice made perfect.

And Nick was about to see the result of all that practice.

She had been prepping his cock, which was now slick with a nice sheen of her saliva. Even with her expertise Sabrina knew that the older boy was packing a real jawbreaker - she had given it to him, after all. With her new reality it made sense that she super-sized his package; she didn’t consider herself a size-queen but like she had said, she didn’t get to enjoy a dick this big very often. It was her chance to really test her skills and impress a cute guy at the same time.

Her thin lips parted and her mouth opened wide so she could stuff his fat cockhead inside. Sabrina held him there for a moment, her cheeks caving in slightly from the suction and her tongue swirling around him in wide strokes. Nick groaned when she began to slide the side of him into her mouth, looking down in amazement as inch after inch of his huge fuckstick slipped into this dainty girl’s greedy maw.

“H-Holy shit…” He moaned out, his fingers entwining in her hair.

He tightened those fingers into a solid grip when he hit the back of her throat. Nick fully expected that to be the extent of it, barely half of his dick making in. It was still a great effort, far more than most other girls could manage given how much they had to stretch their jaw in order to accommodate him.

“Oh my G-God!” Nick gasped, his head rolling back in pleasure from the surprise as Sabrina pushed her head forward and began to envelop his cock in her warm, wet, tight throat.

She eased forward, letting out soft gulps of effort as more of Nick’s length disappeared into the eager girl’s mouth. He could feel her throat gripping him with every difficult swallow; he had no idea how she managed to suppress her gag reflex, not knowing that Sabrina had lost her ability to gag well before the two of them had met. It was an arduous, airway-blocking process, but eventually her nose pressed into his pubic bone like she had crossed the finish line. Her eyes were watering but she looked up at him victorious, and Nick reveled in having one of his long-time fantasies playing out at work of all places, with the mousy unassuming girl he had the hots for.

Then her head began to bob.

Sabrina was intent on giving Nick the throatfucking of his life and the poor hung boy wasn’t prepared for the fervor she was bringing. She had gotten past the hard part and soon lurid wet ‘slurps’ and ‘glurks’ were echoing off of the walls.

“Unnhh, fuck Sabs!” He moaned louder than he should have, but all pretense of keeping things stealthy were out the window.

Where was this coming from? The Sabrina he knew was the kind of girl to apologize when a customer spilled coffee on her; she definitely wasn’t this cock-hungry maniac that was driving his dick into her mouth like it was her job. Her hands were keeping busy too, the few inches of his shaft that was left exposed getting treated to firm pumps that were much more confident than the exploratory touches she had been giving him earlier, her other hand cradling and massaging his plump nuts in its palm.

It was all so sudden and overwhelming, and Nick could barely manage a strangled warning in time.

“F-Fuck Sabs, I’m gonna-!”

He erupted, shooting the biggest load of his life directly down her throat while she milked his climax out of him. He was left reeling, and Sabrina began the process of slipping him out of her mouth, strings of spit and cum connecting her lips to his flagging, spent cock. She grinned up at him like a champ, face wet and makeup starting to run. The girl casually lifted her apron up to wipe the mess away while Nick still tried to parse what had come over her, the gears in his head only starting to turn when the card he was clutching in his left hand drew his attention with an incessant:

BZZZTT!
