A/N: Thaddeus toys with the heroines.

-x-X-x-

Fuck it. Staring at Jennifer Walters in all her pale nudity, Thaddeus makes a decision then and there. Flashing the lawyer a wide grin, he puts a note of wonder in his face and voice as he looks her up and down, and then looks down at his own erection.

“You know, normally I’d say I shouldn’t be. Hell, I just got done fucking a pair of gorgeous babes all night long. And then I have you three here all of the sudden and it’s… well, somehow I don’t feel remotely exhausted. In fact, I feel better than ever. So yeah Jen, let’s fucking go.”

He’s become such a good actor; Thaddeus thinks to himself as he watches a flicker of uncertainty and guilt appear in Jennifer’s eyes. After all, she and her friends all know the truth… and they think he doesn’t. They know he’s not just some normal young stud they’ve decided to take turns being fucked by like some twisted reversal of a particularly raunchy bachelorette party.

Still, the guilt only lasts a second because at the end of the day, the woman who is secretly She-Hulk is still incredibly horny and hopelessly aroused, her tongue tracing out to lick her lips lustfully.

“… Let’s fucking go.”

They meet in the middle, but Thaddeus isn’t playing around anymore. He grabs Jennifer before she can do anything and spins her around, lifting her up into the air. The gorgeous raven-haired lawyer squawks at this, but Thaddeus just grunts as his muscles bulge and he proceeds to impale her on his cock right then and there. Legs spread, feet dangling, back against his chest, the older woman can only moan and reach back to clutch at him for dear life.

“F-Fuck… getting rather cocky there, Thad~”

Smirking, Thaddeus squeezes Jennifer’s thighs where he’s holding them, listening to her gasp in response to the mild discomfort.

“You like my cockiness Jen, don’t try to pretend you don’t.”

Whatever she might have said in response, he doesn’t give her a chance to say it. Instead, he bounces her up and down on his cock, a yelp erupting from her lips… and then he keeps bouncing her, fucking her with just a bit more of his superstrength than previously shown to the three women. But then to be fair, they shouldn’t be surprised by that. They all know he gets stronger from having sex at this point. Really… they only brought this on themselves.

Jennifer’s wanton moans fill the air as Sue watches on… at least until Janet suddenly shows up in front of the kneeling blonde. Pulling her into an incredibly lewd embrace complete with a makeout session like she expects to be able to scoop some of his last load out of Sue’s mouth, Janet really goes to town on the other woman… allowing Thaddeus to put his plan into action.

He starts out slowly of course, not entirely because he wants to, but out of necessity. Utilizing the power he’d gained from Janet Van Dyne; he starts increasing his size by mere centimeters at a time. At the same time, he’s fucking Jennifer harder and harder, gradually escalating things as the sound of their rough, savage lovemaking fills the room.

SMACK! SMACK! SMACK!

“Oh god… oh god, oh GOD!”

Jennifer’s gurgling cries get louder and louder as well, and maybe if the other two women weren’t so distracted with each other, they might have noticed something was up. But whether it was his new Luck Powers helping him along with his plot or just plain good planning on his part, things go exactly according to Thaddeus’ intentions.

He fucks Jennifer so hard, so fast, that on her next explosive orgasm, she has a little accident.

“OH FUUUUUUCK!!!”

… And goes green. Thaddeus grunts as the pale, raven-haired lawyer goes from a couple inches under six feet to more than a half a foot over six foot. On top of that, her body explodes outwards, her arms growing bigger and muscular, her legs still dangling but suddenly twice as large, and her bust and hips and ass also expanding.

Of course, by this point in time, Thaddeus has grown to over seven feet tall and is easily able to carry the transformed superheroine, even as his cock is suddenly tightly gripped by her super cunt. Heh, if he were a normal man, the explosive climax she’s still riding out would probably have pulped his penis… but he’s far from normal, meaning even now that she’s gone all green, his dick is still inexorably stretching out her pussy, regardless of how muscled it is at this point.

As She-Hulk shudders in his arms, moaning up a storm, Thaddeus has his eyes shut for a moment, groaning in pleasure and pretending to ride out the orgasm with her. Then, he opens them… and promptly starts to ‘freak out’.

“What the… holy shit, what the fuck?!”

His alarm causes Jennifer to squawk as she realizes what’s happening, looking down at her now very green body. And of course, his words cause Sue and Janet to break apart and glance over as well, only to go wide-eyed at the sight of their friend blowing their cover.

“Shit… shit, shit, shit!”

Jennifer is quick to scramble out of his arms, and Thaddeus is quick to let her. Of course, once she’s standing on her own two feet, looking chagrined at being caught in the lie, Thaddeus takes a moment to ‘realize’ his own situation… and promptly freak out even more.

“Holy shit! Why am I so huge?! What the fuck is happening?!”

Out of the corner of his eye as he has his little panic moment, Thaddeus watches Jennifer exchange hopeless glances with Sue and Janet. Finally, Sue rises to her feet, holding up her hands placatingly.

“Stay calm, Thaddeus. We might have… hid our true identities a little bit. Sorry, but it was with the best of intentions. Yes, Jen is She-Hulk. I’m Susan Storm, aka the Invisible Woman, and that’s Janet Van Dyne, otherwise known as the Wasp. We’re heroes. You don’t have to be afraid.”

Jennifer, having crossed her arms over her chest at this point a little defensively and more than a little insecurely, pipes up from there.

“Nothing to be afraid about there. He was manhandling me easily, even after I transformed.”

Thaddeus whimpers, which is no doubt a weird sound coming from his current appearance. Still, he’s got a role to play, and he’s going to play it to the hilt.

“… I don’t understand. What’s going on?”

Janet finally rises to her feet as well… and flares out her translucent wings behind her.

“If I had to guess? You’re like me, Thaddeus. Either that or a lab experiment like Jen and Sue.”

Both other women squawk at that casual descriptor, but Janet blows right past them as she steps closer to Thaddeus, seemingly unafraid of his current size and strength. The pixie of a fashion designer even goes so far as to reach out and run a hand over his muscles as she hums.

“… Tell me, have you lost any time recently? Any chunks of memory missing that you can’t account for? Or have you otherwise been a part of any experimental programs by the government or otherwise that involved injecting you with strange substances? And finally, have you come into contact with any sort of alien or mystical material, something that’s clearly not of the mundane world that you might have touched or even just been near and felt strange afterwards?”

Thaddeus blinks at Janet’s rather thorough questioning, not even having to feign his surprise and mild confusion at the sudden interrogation. Slowly, he shakes his head.

“… No? And no. Also no.”

Maybe he could have tried to lie about one of those other things she mentioned, but the best lies were laid down to bed alongside truth in his opinion, so he figures he’ll stick with what he actually knows so he can avoid the most obvious pitfalls. And indeed, upon hearing his answers, Janet smiles smugly and nods her head.

“As I thought. You’re one of mine then. A mutant, like me.”

Feigning surprise, Thaddeus gapes in response, injecting a bit of a voice crack into his voice.

“R-Really? I’m… a mutant?”

A flash of something dangerous appears in Janet’s eyes at that, even though he’d been careful not to inject any disgust or loathing into his voice.

“Is that a problem, Thaddeus? Don’t hate mutants, but when it becomes you, suddenly you aren’t a fan of the idea? Is that it?”

Thaddeus frowns in response, furrowing his brow and shaking his head.

“No… of course not. I just… I’ve got a football scholarship to ESU. A full ride based on my physical abilities. What the hell are they going to think when I show up over a foot taller to practice tomorrow?”

Janet looks appropriately chagrined at his explanation, taking a step back and biting her lower lip. It’s clear she doesn’t have an immediate answer. Jennifer, meanwhile, does… but it’s not a very good one.

“Steroids?”

The green-skinned woman’s attempt at a joke falls flat with pretty much the entire room, making her huff and duck her head in embarrassment. Giving her friend a look, Sue turns back to Thaddeus, a curious glint in her eye.

“Okay. We can figure this out. Not to toot my own horn, but I’m not just Reed Richards’ girlfriend… er, ex-girlfriend. I’m a scientist as well. First things first, I think we all noticed it… your mutation, if that is what it is, seems to be based around sex and getting power from sex… as well as giving in turn. Full disclosure Thaddeus, but we all got stronger when you fucked us.”

Thaddeus doesn’t have to feign his surprise… he honestly wasn’t sure if they would tell the truth about that. Judging by the looks that Janet and Jennifer give their blonde friend, they aren’t quite sure they were going to either. It’s not quite anger or admonishment on their faces, but there’s certainly something uncertain in their gazes.

Ignoring them, Sue bulldozes right on through, staring at Thaddeus’ current form.

“Maybe… maybe this isn’t a ‘new normal’. Maybe this is a… transformation? Maybe you can still reverse it…”

“Oh! Yeah, maybe he got a version of my power! Err, though that might mean he’s angry right now. Or just particularly sexually charged… how ARE you feeling at the moment, Thaddeus?”

Frowning at Jennifer’s question, Thaddeus pretends to consider it briefly while looking down at his truly gigantic hands for a moment, opening and closing them in the process.

“I feel… strange. Confused. Upset. Uncertain. But… strong.”

Jennifer snickers.

“Heh, yeah. That’s definitely me. Okay, try this then… breathe with me. In… and out… in… and out.”

Thaddeus follows along with Jennifer’s words, inwardly amused. He grows even more amused when Jennifer’s little breathing mantra actually calms her down so much that she loses hold of her She-Hulk form. Obviously she didn’t need to be THAT angry to hold onto it from what he understood, but even still.

At the same time, he goes ahead and throws her a bone, as well as just doing it to throw them all off too, and slowly begins dialing down his own transformation with every long breath he takes. Until finally, he’s back at his ‘base’ size and looking down at himself in wonder.

“H-Holy shit…”

The three heroines all continue to eat up his act, looking a mixture of concerned, amused, and affectionate for him. Janet is the quickest to step forward and suddenly wrap her arms around one of his arms, which while shrunken down now, is still huge for someone of her size.

“As a fellow mutant, I think it would be best if I were the one to show Thaddeus here the ropes, ladies. It’s not that the two of you would mess it up or anything… but you’d probably mess it up.”

Whoa now. That was rather cutthroat of the fashion designer. Was she seriously trying to stake a claim on him? Needless to say, both Sue and Jennifer are just as incredulous as Thaddeus in the face of Janet’s words.

“Oh! You audacious bitch! What the hell do you mean mess it up, huh? He clearly has some form of my powers, so of course he needs my help!”

Jennifer’s words would make sense… but apparently she and Sue aren’t presenting a united front here, because the blonde steps in from the side and crosses her arms over her own chest as she shakes her head.

“I’m pretty sure she’s talking about you transforming into the She-Hulk mid-fuck and completely blowing our cover, Jen. You kind of did mess things up. If you’d kept your cool, we could have all brought Thaddeus up to speed about his powers together, in a calmer manner. But you kind of made a mess of things. Still, I don’t see how I messed anything up yet! And besides, it’s not like we know for a fact that Thaddeus is a mutant! He could still have been experimented on as a child, for instance!”

… It said something about their world that Janet pauses briefly at that idea before ultimately shrugging in response.

“Experimented on as a baby and mutant are practically the same thing, really. As for how YOU messed up… well, there is the fact that you blew our identities after Jennifer blew hers. Telling Thaddeus who you were is one thing, but telling him who I am was out of line, don’t you think?”

“He would have found out soon enough anyways! You would have told him!”

“Maybe, but at least it would have been my choice!”

… They were fighting over him. They were honest to goodness bickering over him, like three hyenas brawling over a piece of particularly succulent meat. His eyes ping-ponging back and forth between them all, Thaddeus can hardly believe his ears. Where had their solidarity gone? Why were they suddenly being so catty with each other? Why were they suddenly at one another’s throats?

Was this his Luck at work somehow? Was he going to be asking himself that for the rest of eternity, or would he eventually get used to it enough to stop being concerned?

Either way, one thing was for sure… he needed to step in before things got too heated. With the three heroines sniping at one another over him, it seemed that Thaddeus was to be the deciding vote…
