“Gagkh! Gagkh! Gagkh!”

Thaddeus groans, tilting his head back as he enjoys the ‘tender’ affections of the young Asian woman in a crouch before him. Stacy Li was one of the more popular girls in the school, but that didn’t stop her from coming to him for his… help. Not that anyone who caught wind of what they were doing back behind the school building would be all that surprised even if they did find out.

After all, Thaddeus was your stereotypical jock. Standing at a couple inches north of six feet, broad shouldered with a chiseled jaw, he even had the blond hair and blue eyes to make him really shine. He was literally the Quarterback of the Football Team in fact. Stacy herself was no slouch when it came to high school’s social hierarchy. The girl was definitely one of the popular ones, just like him. That was half the reason she’d had the confidence to approach him about this in the first place.

As she slobbers up and down his knob, Thaddeus leans back against the wall behind him, watching her work. His cock is clearly the longest and biggest she’s ever dealt with, if she’s ever even blown a guy before at all. Her experience or lack thereof makes it likely she’s not fellated anyone before him. Her enthusiasm is nice and all, but it’s a poor substitute for skill in this regard. He probably would have cum by now if she were better at what she was doing.

Pulling back for a moment, Stacy pants, her perky breasts heaving in her cute little top as she gives his saliva-coated cock a few strokes and him a big, winning smile before returning to her task. She gurgles her way down his shaft like a woman possessed, eager to receive her reward. But she’s going to have to do better than this if she wants him to cum before-

BRRRIIIIIING! BRIIIIIIIIIIIING!

Thaddeus twitches, as the final bell for the school day suddenly rings. They’re officially late to First Period, but rather than pull back in a panic, Stacy just goes all the harder. She’s desperate and more than willing to be tardy for this. Truth be told… so is he.

It’s only a couple minutes more anyways before Thaddeus finally tips over the edge. He grunts, cumming in her mouth. He doesn’t ask here if she wants it anywhere else, that would ruin the point. He also doesn’t warn her though, a little perturbed by how long she took. Stacy is prepared nonetheless, sucking down his load like there’s no tomorrow, gurgling away at it as she guzzles his jizz down like her life depends on it.

It doesn’t, but her grades do. As she drinks his cum and the oral sex comes to a close, Thaddeus’ breath hitches. He feels it in his chest, the familiar rush of fresh vitality and the boost he gets from whenever he completes a sexual act.

Stacy rocks back off of his cock, a tendril of cum connecting her lips to his dick as she gasps, feeling the same. Well, not quite the same. Hers is a little different, from what Thaddeus understands.

Quickly wiping the back of her mouth with her hand, Stacy hops to her feet and gives him a wide grin.

“Thanks Chad! You’re a life saver!”

Thaddeus shakes his head.

“Please, call me Thad.”

But it’s too late, Stacy has already run off and his quiet murmur falls on deaf ears. Letting out a sigh, the blond blue-eyed giant of a young man sets about tucking his cock back into his boxers and fixing up his clothing. If she knew the truth, Stacy Li probably wouldn’t have been so gung-ho about servicing him. No one but him seemed to understand quite what was happening, but by now Thaddeus had a pretty good idea.

Basically, whoever he gets with gets a boost to their mental and physical after having sex with him in some way. He gets one too. However, HIS boosts are permanent, theirs are temporary. He probably wouldn’t have even noticed if it weren’t for the slowly stacking effect. He WAS an incredibly handsome high school jock after all, so yes, he got a lot of pussy.

Shaking his head, Thaddeus grabs his backpack and begins heading for First Period. He’s tardy, but as the School Quarterback, it’s not likely to matter.

His life has certainly been different, ever since he figured out he had powers. He’d become the ‘good luck charm’ of the popular girls after one of them got an A on her math test the day after giving him head. In fact, Stacy had just got done blowing him because she was hoping to pull an A on her history midterm today.
