In which Madelyne makes her move and Thaddeus enjoys himself to a certain extent.

-x-X-x-

The conversation with his Biology Professor so far had actually been rather engaging. Talking with Madelyne about the X-Gene and other aspects of biology had made the time positively fly by. However, it was obvious to Thaddeus that she was angling for something more than just a lively discussion between the two of them.

He hadn't been entirely unreceptive to her advances either. Even with Storm's warning in his head, Thaddeus couldn't deny that Madelyne Pryor was a beautiful woman with a gorgeous body. Having her make advances on him… well, it was all but impossible to not reciprocate here and there.

That's why, when Madelyne finally makes her move, Thaddeus isn't that surprised. The two of them are sat perpendicular from one another in their little corner of the coffee shop, meaning that all Madelyne has to do is scoot her cute little ass over to the side another foot before she can lean over and kiss him.

That's exactly what the Biology Professor does and Thaddeus… Thaddeus sees no reason to deny her. As her lips press against his, he doesn't pull away or try to stop her. Instead, Thaddeus kisses Madelyne right back, even as his hands run along her sides.

What starts as a passionate kiss quickly evolves into a full-blown makeout session though. Thaddeus is the first one to introduce tongue to the situation, and while Madelyne is surprised for a moment, she quickly and enthusiastically adapts to the change, applying her tongue right back.

The solitude in their corner of the coffee shop and the general low light and empty nature of the business means that they aren't interrupted throughout this experience. Instead, its they who have to end it when Madelyne eventually needs to come up for air long before Thaddeus would have needed to.

As they pull apart, Thaddeus studies Madelyne's face for a moment, from her wide eyes to her red cheeks to her swollen lips. She pants heavily before finally swallowing hard and looking at him like she doesn't quite know what to do next.

Before he can make a suggestion however, she seems to come to a decision all her own, grabbing Thaddeus by the hand and interlacing their fingers together. He raises an eyebrow as she pulls him to his feet and drags him out of their corner. Not towards the door of the coffee shop… but towards the bathroom in the back.

It's a small establishment, meaning that the bathroom is a personal bathroom with a locking door as one might expect. Thaddeus barely has time to make sure no one sees them entering it together before Madelyne has hurried them inside and is locking the door behind her.

As she leans back against the door, chest heaving up and down in her slightly disheveled blouse, Madelyne Pryor stares at him with a deep-seated hunger in her eyes.

"I need you inside of me, Thaddeus. I thought… I thought I could content myself with just a kiss, but I couldn't. I need you to fuck me… please."

Wow. Nothing quite like a drop-dead gorgeous red head telling you exactly what they want from you. Still, Thaddeus does hesitate.

"… Are you sure about this Professor?"

Letting out a lustful growl, Madelyne pushes off the door and stalks right up to him, grabbing him by the front of his shirt and pulling him down into another tongue-filled kiss. Thaddeus' hands instinctively fall to her hips… and then move further down and around to her ass, giving it a hard, deep squeeze as she moans into his mouth.

When they finally pull apart again, she looks at him with nothing but sheer certainty and abject arousal in her eyes.

"I'm sure. And please, call me Madelyne."

Grinning, Thaddeus gives her ass another squeeze.

"Alright, Madelyne."

Pulling out of his grasp, the beautiful red head reaches down and yanks a zipper on the side of her skirt down until the entire garment falls off of her body and reveals her panty-clad lower half. Then, she moves over to the bathroom sink and grabs hold of it, bending over for him right then and there. Looking back over her shoulder at him, she bites her lower lip as she wiggles her ass in his direction.

"Please… I need you~"

Freeing his cock from its confines, Thaddeus makes his way over to her, his fingers sliding along her bared flesh now as her breath hitches in anticipation. Hooking his thumbs into the waistband of her panties, he pulls them down slowly but surely, all the way to her knees. He has to peel them off of her crotch, such is her wet arousal.

Finally, her drooling pussy is exposed to him. All of this foreplay has really done it for her, Thaddeus notes. She really is desperate for him and his cock. Well then… he'd just have to give it to her, he supposed.

With a grunt, he thrusts into the beautiful Biology Professor from behind. Madelyne gasps and moans, staring at herself in the mirror for a moment as she gets properly fucked. She's incredibly tight around his member, her pussy walls clenching and squeezing along every inch of his dick as he invades her from behind.

Truth be told, it's hard to go slow. She feels too damn good, like she was made for him. More than that, Madelyne insists on pushing back into him as he fucks her, meeting his every thrust with a backwards thrust of her own.

And of course… there's the begging.

"Yes! H-Harder! More!"

She's getting loud enough that Thaddeus is worried someone in the coffee shop just outside will hear them. Reaching up with one hand, he covers Madelyne's mouth, muffling her squealing moans and begging cries. It doesn't completely stop her of course; she appears to be quite the talker when it comes to sex… but at least she's no longer shouting loud enough for the whole damn building to hear.

"Mmmph! Nnngh!"

SMACK! SMACK! SMACK!

Of course, the sound of flesh slapping against flesh might also be a little audible, all things considered. But it can't be helped. Madelyne Pryor's body is just too damn good not to fuck her silly. And fuck her silly he is, because he can feel her pussy flexing and cumming around his cock over and over again as he pounds her up against the bathroom sink.

If he didn't know any better, Thaddeus would say Madelyne Pryor was… a completely normal woman. Albeit one with an obsession with mutants and mutations, as well as a naughty, naughty slut eager to hop in bed with a handsome stud like him… but beyond that, he would say she was no threat or danger.

The problem was, Thaddeus did know better. If Madelyne was Jean Grey, then he suspected she didn't know it. It was possible she was an amnesiac or something. Her mind might be impossible to read, but she definitely wasn't a telepath… or at least didn't know she was one and had never consciously used such abilities.

However, Thaddeus was beginning to think this really wasn't Jean Grey, especially if they'd buried her body after her death like multiple X-Men had said. So then who and what WAS Madelyne Pryor? Where had she come from and why was she identical to a dead woman?

… Could she possibly be a clone? Thaddeus' first instinct is that it's a silly thought, but given the world they live in, his second instinct is to wonder why they hadn't thought of it earlier.

If Madelyne wasn't Jean Grey brought back to life with amnesia, then her being a clone of the other woman really was the next most logical thing in a world as insane as theirs.

But then that begged the question… exactly who had gone out of their way to make such a clone? And what did they want with him? Because Thaddeus refused to believe Madelyne's placement at Empire State University was a coincidence.

All in all, this led to one simple conclusion… he couldn't let himself cum inside of Madelyne Pryor. Whoever or whatever she was, he didn't know what would happen if he let his powers interact with her. It was possible that nothing at all would happen… but at the same time, it was equally possible that he'd open a whole can of worms that couldn't be closed again.

Fortunately, or perhaps unfortunately… Thaddeus has complete control over himself at this point. He's not going to cum unless he wants to cum. Fucking Madelyne there in the coffee shop bathroom, plowing her up against the bathroom sink until her eyes are rolled up in her head and her tongue is dangling out of her mouth… Thaddeus just doesn't let himself release.

Madelyne is in no state to question it when they're finally finished either. He's fucked her for a good twenty minutes, and while that might not seem like much in the grand scheme of things, its certainly enough when she's cum more than twenty times in those twenty minutes.

Pulling out of her, his rock hard cock slick with her juices but nothing else, Thaddeus holds the shaking, trembling, and spasming woman steady as she slowly comes down from her latest and greatest explosive orgasm yet.

Then, he forces his erection to droop and begins fixing up their clothes, tucking his cock away in his pants and pulling her panties up again while Madelyne is gasping and panting for breath.

There's something a little unsatisfying about it of course, but it's better for him to delay gratification rather than potentially set off a ticking time bomb. Besides, he can't get blue balls anymore for the same reason he can hold himself back from cumming. All thanks to Sage. Though thinking of her did give him something of an idea…

"You… hah… that was… a-amazing."

Smiling as he helps Madelyne put her skirt back on, Thaddeus chuckles.

"I'm glad to hear it, Madelyne."

The glazed look in her eyes begins to fade as she comes back to herself and a slight frown spreads across her face.

"Did you… get off? I don't…"

Smirking, Thaddeus gives Madelyne a distinct 'look'.

"Do you really think a young man my age would stop without getting off, Madelyne? I guess I really am that good if you can't even feel it."

Madelyne blushes profusely, looking down at her admittedly very wobbly legs.

"H-Heh… I'm not sure I'm going to be able to walk straight tomorrow."

Then, she looks up at him hopefully.

"But hey… do you want to come back to my place maybe? For… for drinks?"

The earnest hope in her voice causes Thaddeus to snort. She certainly was persistent, wasn't she? Like a dog with a bone.

"I don't think that would be a very good idea. We both have somewhere to be tomorrow morning, after all. And if I went back with you, I doubt we'd get much sleep."

Madelyne blushes at that, forced to reluctantly nod in agreement. Before they leave the bathroom though, she grabs him by the wrist.

"Will you… see me tomorrow then? Before… or after?"

Thaddeus considers what he's planning to do with the rest of his day for a moment before slowly nodding.

"If it works out, sure. Can't promise anything though."

That seems to be good enough for Madelyne, who beams brightly as though he's just promised her the world. Together, they surreptitiously leave the bathroom once Thaddeus has made sure the coast is clear. Nobody seems to be the wiser about what just happened in there, though… well, whoever used it next might be able to guess.

They part ways outside of the coffee shop once Thaddeus makes sure Madelyne can still walk on her own two feet. The red head assures him that she'll be perfectly fine and in the end, Thaddeus helps her into a cab and sees her off.

Then, he places a call. It's not exactly difficult to get some one-on-one time with Sage, all things considered. She IS supposed to be his Personal Assistant after all.

Meeting in a hotel room is the work of less than an hour and once they're there…

"I need to fuck you until tomorrow morning when I have to leave for university."

The female telepath raises an eyebrow at that, even as she shrugs and begins undressing.

"Am I allowed to know why? It sounds as though you need more of my particular set of skills for something."

Thaddeus nods in agreement, considering how much to tell her. In the end… he'd never told her what he'd found out the first time they fucked. Namely, that Sage's DNA perception power went beyond simple perception. But if they fuck the night away, then she very well might unlock such a thing on her own, so he might as well admit it to her now.

"You have the potential to become capable of unlocking the potential of others. We're going to fuck until both you and I are capable of doing so, as well as making sure my ability to perceive someone's abilities is as crystal clear and granular as humanly possible. Or I guess mutantly possible."

Sage doesn't laugh at his joke. But she also doesn't get angry. Already stripped down to her underwear, the living supercomputer in biological form takes only half a moment to process what he's just confessed to her.

"Fascinating. What would we do with such powers?"

Realizing he's a bit behind; Thaddeus begins to strip naked as well as he explains.

"Well I'm going to use it to get to the bottom of exactly what's going on over at the University once and for all. As for you… you'll do whatever you want with the ability. It's yours, after all."

Sage tilts her head to the side, looking vaguely perturbed at the trust he's putting in her. But to be fair… no matter what, Emma and him will always have the lead on her as psychics. After all, even if he fucks Sage all night tonight, that's not going to measure up to the multiple weekends he's spent with Emma.

"… Very well. Let us begin."

Yes. And then maybe tomorrow Thaddeus would have a better idea of just what the hell was going on with Madelyne Pryor. He might not be able to peer into her head… but maybe he could peer into her very DNA itself.
