Molten

Summary:

"When you had initially heard that Doctor Phosphorous was an equal opportunity employer, with several female goons on staff, you’d been skeptical. You knew the type. And you weren’t terribly interested in henchwomanning for a grabby-handed villain with boundary issues.

But Alex was… not what you expected."

All of the anticipation has been building up to something HOT.

Work Text:

It’s so fucking hot.

Beads of sweat roll from your hairline in a steady drip. They slide into your eyes, melting your eye makeup and stinging like hell. Despite the large industrial fans turning, slow and useless, on the ceiling, the air is heavy and stuffy in the humid warehouse hideout. Not to mention the radiant warmth coming off the glowing cock that stands at attention against your stomach.

Under your palms, Alex’s translucent radioactive skin heats. A brief flare of sensation that reminds you of sitting a little too close to a winter bonfire. From your position astride his lap, you can feel his deepening breaths shifting his hard-on back and forth – the head of it tapping on your abdomen like a warm metronome. When you tilt your face down to look at it again, a drop of sweat slides off the tip of your nose and hits Alex’s pubic bone with a loud sizzle – followed by another flash of heat.

“Gimme a minute.” His words come out rough, forced from his throat, “I’m… taking it all in.”

When you had initially heard that Doctor Phosphorous was an equal opportunity employer, with several female goons on staff, you’d been skeptical. You knew the type. And you weren’t terribly interested in henchwomanning for a grabby-handed villain with boundary issues.

But Alex was… not what you expected.

Sure, he had been the glowing skeleton, bathed in sickly green light and the heady toxicity of simmering nuclear energy. Just as advertised. Doctor Phosphorous. Nightmare made flesh but… he was Alex. Your Alex. Funny and surprisingly gentle Alex.

Doctor Phosphorous felt like a mask. Something Alex could slip in and out of when it was the appropriate time for… well… melting faces and leaving rival gangs decimated. Nothing but smoking piles of blackened bones.

There wasn’t much ass smacking and up-skirt shenanigans from the guy that could burn a hole through metal, flesh, and bone with just the brush of a fingertip.

Not that there hadn’t been attraction, from the beginning. You had been curious. He had been lonely. You lingered after your colleagues had cleared out for the night, sharing jokes and warm beers while Alex reviewed the books. The first time you had kissed him, the shock of it had cost you your eyebrows and given you a nasty blister on your bottom lip.

It had been an agonizingly slow burn from there.

Alex was determined to take his time getting used to the idea. Safety first, and all. Baby steps. Cooling of the heels.

All of which had been leading up to the two of you right here, right now, on a dingy stolen couch with Alex’s pants around his ankles and your thighs spread over his lap. In his rush to undress you, Alex had forgotten himself and your clothes – strewn about the space – still held glowing outlines of his palms and fingertips from where he’d scorched them.

His radiant skin fluctuated between a deeper emerald hue and white-hot flashes of light. It was the closest he could come to blushing. Your naked breasts and belly had already started to sting – like a sneaky sunburn you’d get on an overcast day – and you knew your inner thighs would be red and tender by the time this was over.

A lock of your hair spills over your shoulder when you shift. The end of it abruptly breaking off into a charred, uneven mess. That was on you. Alex had warned you to take it slow. He’d been throwing off sparks since you got naked. It didn’t take a genius to put together that his hand in your hair, plus you getting greedy with stroking his cock, had resulted in a minor fire emergency.

You hold your breath as Alex lazily explores your body. Unnaturally warm hands gliding over your skin. Tracing the outline of your hips. Palming your breasts. Gradually, his light dimmed and the heat of him leveled out to something pleasant and warm. Only where your hands held his shoulders did the skin beneath burn brighter.

“Alex? Is this okay?”

Alex’s reply comes out in the form of a whooshing sigh. Deep, meditative belly breaths. “I feel like it’s prom night all over again,” he chuckles nervously.

The thought makes you grin. “Did you get laid at your prom?”

“Oh Christ, no!” Alex guffaws, covering your breasts with his hands again, “But Mandy Bronstein did let me round second base. So, all-in-all, a successful evening for a nerdy teen.”

You mewl sweetly when he strums your tightened nipples in a subtle, tender motion. Your back arches, pressing yourself into his touch, “Any chance of a home run?”

Alex’s skin brightens once more before returning to the controlled green hue. “You’re not making it easy.” The strain in his voice is just as impatient as the obvious throbbing in his cock.

“I’ll be good.” It’s a lie. You’ll do you best.

“You have to go slow,” Alex insists, already shifting his body more beneath yours, “I’m dead fucking serious. I haven’t done this before, like this, and –”

“And third-degree pussy burns are a huge dealbreaker. I know. Just fuck me!”

The sudden heat between your legs is so sharp it feels like a slap and you squeak, in spite of yourself.

“That’s exactly what I’m talking about,” Alex mutters smugly, “Just don’t…” He pauses, looking into your face for a while. “Just don’t be so you. Tone all of this down.” He waves his hand emphatically over your naked body.

“Got it. Turning the sex appeal down to zero. Cold fish.” You bite down on your lip to keep your smile from spreading any farther.

With calm determination, Alex notches his cock between your pussy lips – sensitive and impossibly slick from your own impatience. You had been dying for this.

Slow.” He reiterates through panting breaths.

And you take it slow. So perfectly slow. Your eyes flutter closed and the air hisses through your clenched teeth as you slowly lower yourself onto his waiting cock. He’s so fucking hard, thick and throbbing from wanting you. It’s a cozy fit, but you’re so wet for him that you take him easily. A shuddering groan reverberates from his skeletal grin when your clit grinds against his pelvis – now fully seated with him inside you.

“Okayokayokay –” his whispers are rushed, frayed on nerves and arousal, “Be still. Just – haah fuck – don’t move.”

Somehow, it’s even hotter than before. His cock feels like superheated iron. The delicious sear of being full and… maybe he’s burning you? You don’t know. You don’t particularly care. Sweat slicks your skin and the air between you and Alex gets steamier. His attention is rapt on where your bodies are joined – his cock buried to the hilt inside you. His countenance is one of composure and his breathing has slowed, but the subtle light show of shifting brightness and shades of green gives away just how tight of a rein he’s keeping himself under.

“Are you okay?” Alex whispers. Compared to the feverish feeling inside you, his hand on your cheek is cool.

You nod, pressing a soft kiss to his wrist and cooing, “I love feeling you.”

Fuck,” he grits out, “Don’t talk like that.”

“I love feeling you,” you repeat yourself, reckless with how much you want him, “I knew it would be good but this is so much better.”

The shaky moan that rattles from deep in his bones spurs you on and your pussy tenses around his length. First, it’s pure impulse, but then you clasp him again; tightening until it feels like you could possibly drag him deeper. Alex’s hissed swear is swallowed by the sssssshhh sound of sudden heat on wet skin. His fingers knead into the fleshiness of your hips, that campfire sensation is back. A subtle warmth that grows higher and shaper. You don’t want to stop and you roll your aching clit against his body, chasing a hint of pleasure before – fuck, that’s hot!

Oh, fuck, like REALLY hot!

“Shit!” You gasp, grabbing Alex’s wrists and yanking his hands off of your body.

Two perfect handprints stand out, angry and red, on your hips and your pussy flutters around him in unexpected hunger. The idea of being temporarily branded by him... smoothing aloe vera gel over the undeniable evidence that he took what he wanted from you. You almost were excited to see how long the burn would last. Inside of you, Alex’s cock is throbbing and twitching relentlessly; apparently, you’re not the only one playing fast and loose with safety protocols.

Alex’s voice is low and gravelly with desire, but the concern is sincere, “Did I hurt you?”

You shrug it off, “In a kinky sort of way.”

“Sicko.”

“You know it, baby.”

He laughs, more at ease, and his temperature comes back down. For a moment, the two of you enjoy easy stillness. Sharing the sensation of being totally wrapped around one another. Finally, Alex sighs and squeezes your knee affectionately, “Maybe this is a good place to stop. For now.”

If you listen carefully, you can almost hear your swollen clit screaming in outrage. You put on your best pouty face, “Do we have to?”

“To be honest, I’m surprised things have gone this well,” Alex murmurs, his attention returning to where your pussy is stretched around him.

You press, “I’ll go slow.”

“Bullshit,” he retorts.

“Maybe,” you tease, bracing your hands on the back of the couch, “but what choice have you got?”

Before Alex can list all the many, many reasons why this is a bad idea, you lift your hips slowly. Feeling him withdraw from you is nearly as sweet as being stretched around him and you bite back a groan when you pause – the head of his cock the only part of him that is still inside.

“Nice and easy.” You reassure yourself, just as much as you hope to soothe him, before beginning the slow descent back down.

Alex’s head lolls back into comfortable surrender – soft grunts and moans of appreciation keeping rhythm with the slow up and down of your pussy on his cock. You ride him carefully, never allowing yourself to go too fast or to switch up the swivel of your hips. Everything in you screams for release, but getting off falls significantly lower on the priority list than making it out of this experience without injury.

Even so…

As Alex settles into the sensations, you pick up your pace slightly – angling your hips so that his cock curves perfectly into that one spot that’s so deep and so fucking good.

“Right there, baby,” you gasp, bouncing with more urgency.

Oooh fuck yeah,” Alex breathes, shivering beneath you. Heat starts to build between your legs and you honestly can’t tell if it’s you or him.

“I wanna cum around your cock.” It’s not a matter of talking dirty. It’s a need.

Alex’s hands fly away from their current position on your waist and grip the cheap polyester of the couch. “Watch that filthy mouth,” he groans, twisting his fingers into fabric, “That’s how people get incinerated.”

“That would be too bad,” you sigh on a breathy giggle, stilling with is cock fully buried in your pussy, “Not to mention you’d likely never get laid again.”

Whatever snappy comeback Alex had been preparing dies on his tongue when your fingers curl down over your clit. It’s hard to say – with a skull for a face – but you swear you can see his eyes widen in shock.

“What are you doing??”

“I’m touching myself.”

Alex watches, slack-jawed, as you expertly circle your own clit in a practiced touch. “Why are you touching yourself?”

“You’ll see.”

It doesn’t take long. You had been impossibly horny all day in anticipation of this little experiment. Alex’s excruciating caution hadn’t put a damper on your need at all. Quite the opposite. With every touch of your fingertips, you could feel Alex’s cock jerking inside you. Knowing how riled up he was… imagining what all you might get away with next time.

Fuck, baby, I’m close –” you whine, high-pitched moans sneaking into your gasping breaths, “ – I’m gonna cum – oh fuck – oh fuck, ALEX!”

Fuck!!!” Alex yelps, “Christ, your pussy is tight!”

It all happens so fast after that.

Ugly black smoke, noxious with the scent of burning chemicals, pours out of two neat holes in the couch – where Alex’s hands have punched right through, balled up into flaming fists. A sudden sheet of cold, stagnant water pours over the both of you – raining down from the emergency sprinkler lines above. Steam rises off of Alex and envelopes you both in a thick cloud. For a moment the two of you regard each other, breaths gradually slowing and goose pimples rising on your upper arms as a soaked-to-the-bone chill replaces all of the heat generated between the two of you.

“All-in-all.” Alex grumbles, withdrawing one arm from the melted couch cushion, “Not bad for a first attempt.”
