“Nothing’s wrong, stud. And we’re definitely ready for Round Two~”

Before Sue or Janet can truly react, Jennifer is already clamoring up into Thaddeus’ lap, arching her back as she slides down his cock and impales herself right then and there before beginning to bounce.

For his part, the hunky young man grabs Jennifer by the hips, and then by the ass, his fingers digging into her flesh as he groans in approval and leans in to feast on her tits. Susan exchanges a somewhat helpless glance with Janet Van Dyne in the face of this sudden escalation.

Neither of them thinks that it’s because Jennifer is being greedy or power hungry or anything though. Sue knows this because she can see the arousal in Janet’s eyes as well as feel it welling up within herself. And she suspects Jennifer shares that arousal with both of them. Put bluntly, they’re all too fucking horny to back out now.

And really, who can blame them? Thaddeus is one of the hunkiest, well-hung men that Sue has ever come across. Sure he’s a little young compared to them, but he really knows how to please a woman, and that’s coming from barely doing anything besides oral with him so far!

… At the end of the day, Sue is confident that they’ll tell Thaddeus what’s going on when all is said and done, and help the young man navigate whatever comes next. They all just needed to… clear their heads for a moment, and what better way was there for doing that then through multiple orgasms?

Sue bites her lower lip as Jennifer suddenly cries out, arching her back in a way that makes it clear she’s already getting a start on those multiple orgasms right in front of their eyes. And Sue has to admit, she can hardly wait for her own turn. Janet apparently feels the same way, because rather than waiting, the brunette fashion designer suddenly invades Sue’s personal space, gently turning her head and kissing her as well as licking the cum from Sue’s face.

Blushing for a moment, Sue nevertheless gets into things by reciprocating and returning the favor, letting herself get swept away in the moment.

It’ll be fine. They’ll explain things to Thaddeus later. He doesn’t need to know everything about them right this minute…

-x-X-x-

Thaddeus, of course, knows exactly who he’s dealing with by this point. He might not have known what was going on when he’d first allowed Lady Luck to guide him, but he WAS a telepath. And while he hadn’t done a deep dive into any of their minds, uncertain of what people like them might be able to detect if he went too far, he also didn’t really need to.

Surface level alone had been enough for Thaddeus to make the connections, putting names to faces, and faces to superpowered identities. Heh. Sue, Jen, and Jan. Not exactly trying to hide it, were they?

Though to be fair, as he bounces Jennifer Walters, aka the She-Hulk, up and down on his cock, Thaddeus has to admit that he wouldn’t have recognized them all on the street or anything. He’d heard of them in passing, but didn’t know them all that well, even as a fan. They were basically celebrities who existed outside of his personal sphere of awareness. Known by many? Yes… but not known by him.

Until now, anyways. Seizing upon Jennifer as she cums again and again for him, Thaddeus growls lustfully, getting closer to the edge himself. He’d felt a small surge when he’d cum on all three of them, but he wasn’t entirely sure it’d been enough to give him even weak copies of their powers. He had, after all, only ejaculated onto their bodies.

But direct intercourse with each should solve that problem, or so he figures. That’s why Thaddeus doesn’t hold back or try to prolong this encounter as far as he could. After the sixth or so climax from the currently human She-Hulk, Thaddeus looks her in the lust-filled eye.

“Going to cum soon…”

They hadn’t bothered to pull out any rubbers. But that doesn’t mean he’s just going to cum inside of them without permission. That said…

“I-Inside… I’m on the p-pill, it’s fine.”

Her surface thoughts confirm it. She’s on some sort of super birth control developed by her cousin, Bruce Banner, aka the Hulk. It works specifically with Gamma Individuals, a precaution developed to make sure they weren’t all popping out babies capable of Hulking Out at a moment’s notice.

Well, if he has permission… Thaddeus nods sharply, before driving up inside of Jennifer one last time. His cock kisses the entrance of her womb, causing her to gasp and her eyes to roll back for a moment as he cums inside of her. She spasms her way through one last climax alongside his release, and both of them feel a surge of power rush through them.

Though of course, Thaddeus doesn’t let anything on, even as he slowly pulls Jennifer off of his cock and gently lays her out on the bed beside him. He’s pretty proud of his little ruse, frankly. When the three women had decided to keep him in the dark about their identities, Thaddeus had decided to play the young, uneducated rube, just to see how long they chose to string him along for after realizing he was empowering them with sex.

So far, it seemed that was going to be pretty long. Janet Van Dyne is the next to rise from the floor, her eyes glued to his big fat cock, still hard and twitching with arousal. Unlike Jennifer, the pixie-like brunette spins around instead of climbing into his lap and backs her cute perky posterior back towards him.

Looking over her shoulder at him as she arches her back with a smirk, Janet pushes her ass crack against the underside of his messy meat pole… prompting Thaddeus to grunt and reach out, grabbing her by the hips.

He… thinks he gets what she’s going for. And if he’s got it wrong, Thaddeus is confident she’ll tell him. Surging up from his seated position at the end of the bed, Thaddeus seizes upon Janet’s hips… and lifts the short, compact fashion designer up into the air. As anticipated, her wings buzz to life on her back as he does so, alleviating the weight in his hands by a lot even as her feet leave the ground.

She’s basically hovering for him as he steadily slides her back onto his cock, her own hands reaching down to anchor herself on his thick wrists as she moans happily.

“Oooh, f-fuck… love me an adventurous lad~”

She winks at him teasingly from over her shoulder, causing Thaddeus to snort and fuck her harder, until she’s a moaning mess being bounced ruthlessly up and down his cock. He doesn’t go too far with it, of course, making sure to keep his enhanced strength well in check so he doesn’t accidentally harm her.

However, he’s certainly not gentle either, nor does he get the impression that Ms. Van Dyne wants him to be. Her back arching, her wings buzzing away, and her ankles crossed down below as her toes curl in open air, the beautiful brunette fashion designer cums again and again on his dick.

Before he can even ask though, Janet is quick to call back to him.

“Fill me up, big boy! I’m very much on the pill~”

Her birth control isn’t the specially made kind that Jennifer’s is, but Thaddeus can tell she’s telling the truth all the same. With a grunt and a nod, he enters the home stretch with Janet, plowing the pixie-like woman hard and fast, bouncing her back and forth on his cock like a sex toy.

Then, he fills her to the brim just like he did with Jennifer, pumping her tight cunt till it can take no more. Only once the surge of power is over and he’s done emptying his balls for a second time does Thaddeus pull out of her and carefully place her down on the bed next to her friend. And then there was one.

Turning to Susan Storm, Thaddeus raises an eyebrow at the blonde, who blushes in response. She hesitates for a moment before falling backwards and spreading her legs. Propping herself up on her elbows, she bites her lower lip as she shows off her glistening, dripping wet cunt.

Thaddeus grins and joins her on the floor, one hand grabbing a hip to steady her, while the other gropes one of her tits in a way that has her moaning up a storm in response. This was supposed to be HER rebound from the start after all, but he simply hadn’t been able to resist the urge to go for all three at once. And to be fair to him, they hadn’t been able to resist either.

As his cock slides into Sue, Thaddeus peers down at her, watching her eyes flutter and her pale flesh become more and more flushed from the impact of having him buried inside of her. Grunting, he continues going until he bottoms out, before setting a steady pace. Not quite as rough as he’d fucked Janet though, mostly because he wants to speak to the beautiful blonde bombshell.

“So… I’m the rebound, yeah?”

Blinking, Sue looks up at him, nodding through her moans.

“Y-Yeah… I… my friends were right. I n-need to stop going back to Reed. I need a proper, clean break. Mm, this big fat cock might be just what I need… so go ahead and use it to s-screw my head on straight~”

Thaddeus chuckles at the dirty talk, his fingers rolling one of Sue’s nipples between them. Still, if that’s what she wants, who is he to deny her? With a lustful growl, he picks up the pace and begins to really screw the beautiful blonde.

Sue cries out, immediately tipping over the edge from the increased pace and experiencing her first explosive orgasm upon his cock. And then she keeps cumming because he keeps fucking her, not letting up for even a second. Scooping some of his drying cum from her body, he pushes his fingers against her lips and she welcomes them in, sucking them clean as she stares up at him with big, blue eyes.

His mutation hadn’t taken one-for-one powers from either of her friends so far. From Jennifer, Thaddeus could tell he hadn’t gotten any sort of transformation or anything like that. More like he could, if he wanted to, amplify his already existing strength and speed without any outward alteration. It was an extremely good power even on its own, though fucking Jennifer a few more times to increase it would be awesome.

It meant that going forward, if he got in too much trouble, he could amplify his already immense base attributes for a period of time that would hopefully last long enough to see him through said trouble.

Janet’s power on the other hand, reminded him a lot of what he’d gotten from Mystique originally. He could now very slowly decrease or increase his size, though it would take several minutes to go either direction, and then several minutes again to go back to normal. Combined with Mystique’s power, it did basically make him the perfect infiltrator… though how valuable that would be given his lifestyle, Thaddeus couldn’t say.

Still, when it came to Sue… well, he’d find out soon enough.

PLAP! PLAP! PLAP!

Sue moans under him as Thaddeus drives his hips forward and slams his cock into her pussy again and again. She shudders and quivers beneath him, her beautiful breasts bouncing and shaking and jiggling all over the place as he gives her exactly what she said she needs… her head screwed on straight.

He didn’t pretend to know a lick about her relationship with Reed Richards. It was another name he recognized as someone famous but didn’t know much beyond that. He knew, of course, that they were both in the Fantastic Four, and that the Fantastic Four fought bad guys. But… well, beyond that, it’d just never been all that relevant to his interests.

Still, what Thaddeus senses from Sue as he drives her to orgasm after orgasm is a mixture of deep satisfaction… and relief. So maybe her friends are right and this was precisely what she needed to truly break away from whatever toxic relationship she was in with Richards. In the end… Thaddeus was just in it to get laid.

Sue, unlike the other two, is NOT on birth control. So rather than asking, just in case she might lie to him, Thaddeus pulls out and slides his cock between her tits instead, guiding her head back to his member. No sooner have her lips suctioned down around his dick almost subconsciously, than Thaddeus begins to cum and Sue’s eyes widen as she starts to swallow down his jizz.

She drinks his cum like a good girl to be fair, and Thaddeus groans as she guzzles it all down. There’s still a sizable surge of power between them to be fair, probably because most of the encounter was still intercourse. But when he finally pulls back, she does pout up at him questioningly, prompting Thaddeus to explain with a chuckle.

“You just got out of a bad relationship you’ve been trying too long to make work, Sue. I knew you weren’t on birth control.”

A lie, but one that Sue eats up easily as she blinks in surprise before acceptance spreads across her face. And not just Sue either, as a laugh comes from behind him and he turns to see Jennifer Walters grinning at Sue.

“Man, he has you pegged, Sue!”

Hands on her hips, the superpowered lawyer still isn’t using her She-Hulk form… but she gives him a challenging, lecherous look all the same, even going so far as to lick her lips as she gazes down at his still hard cock.

“I can see you’re already ready for Round Three, stud~”

Thaddeus hums, watching Jennifer for a moment. He’s not going to pass up the chance to fuck her some more of course. The power he’d gotten from Sue was a slow form of Invisibility, and one that wouldn’t work with clothes, so he still considered Jennifer’s ‘gift’ to be his favorite and the one most worth improving upon.

… That said, should he mess with them a bit more? Or keep up the act and play dumb all the way through? Hm, or maybe even strike a middle ground of sorts…
