Can you really blame him when he’s been having the worst week known to mankind—models for inhibitor just wouldn’t work, his spidey senses are all fucked up and cranked to the limit that he feels like his brain was slowly draining out his ears, and— oh god— the organic webbing— he still can’t control it well and it gives him the chills every time.
The weather is getting hotter, his human and arachnid hormones are out of balance, metabolic rates are unstable— with everything considered, activity levels are at an all time high and he’s one flick away from losing it. And it only took one horny look from his crush for Matthew’s mating senses to be triggered.
Fuck. Fuck. “Fuck—” Matthew let a moan escape from his throat, the heat of his voice spreading on his face as he gets muffled by his mask. “Gunwook,” He grimaced as he slowly sank on the blunt head of Gunwook’s cock on his too slick, too ready hole.
“You feel so good, so perfect around me.” The man below Matthew groaned harshly, his hand tightening on Matthew’s naked waist that will surely leave a mark.
You really can’t blame Matthew when he accidentally crashed into his friend’s dorm after a fight with Scorpion that triggered his imbalance again. He swung and swung mindlessly, head empty, dark-eyed, and purely following his instincts until he crashed onto a window and blacked out.
The moment he gained consciousness, he was greeted by Gunwook who insisted on taking care of the hero on his bed. One thing led to another; a series of the taller man’s worried what’s happening, Spiderman? Are you okay? Is this okay? As Matthew, already muddled on the head, started ripping his suit off himself and begging the other, I need you. Please, I need you so bad. Can you help me? I swear I don’t usually do this but please, please, please—-
When the sweet, musky smell that filled his room hit his nose, Gunwook felt his head short circuiting, as if he’s now only led by the pure primal instinct of heat and procreation. He helped the shorter man to undress, immediately latching to his battered, yet smooth and firmly toned skin. Matthew, already needy as he is, whimpered when he couldn’t kiss him because of the mask. Thankfully, he still hadn’t lost all of his mind and kept the mask on. It stays on no matter what.
It stayed on when Matthew let Gunwook watch as he opened himself up, sitting across the other man with his legs spread apart for him, head throwing back as he dug onto himself deeper and harder, leaking through the younger’s sheets. Gunwook couldn’t hold back, shivering as he stroked himself from the view of the mighty superhero fucking himself open for Gunwook on his own bed. It stayed on when Matthew took a hold of his wrist and guided his hand to his inviting hole, Gunwook moaned for himself as he felt the tight heat of his hole swallowing two of his fingers easily as he’s already dripping. It stayed on as the sticky, translucent liquid squelched perversely and steadily oozed out of Matthew as Gunwook’s thick fingers rammed deep, his head throwing back.
Now, Matthew has Gunwook under him, fingers coiled tight on his hair as he slowly sat himself down on the younger’s outrageously thick cock. He breathed heavily as each inch sunk onto him slowly, the muscles on his thighs shaking along with his clenching hole swallowing Gunwook’s girth and length. When he finally filled himself full, he panted hot and heavy against Gunwook’s chest, his saliva disgracefully soaking through his mask.
Gunwook felt it all, also intoxicated with the man’s heat and scent and need for him. His heat, tightness, the weird slick that perfectly helped the otherwise painful penetration. “S-spiderm—”
“Hyung, call me your hyung.”
Gunwook’s eyes rolled up, groaning as he felt the older clench against his hardness. “Fuck, hyung, hyung, hyung—”
“Shh, it’s okay, baby. I’m sorry. I’m so sorry for using you. It’ll be over soon, I promise.” Matthew breathed heavily against his ears, swallowing his own sounds as he finally started moving his hips. Slowly at first, whispering words of comfort for the younger who’s already crying from the pleasure. Then picking up the pace when he said, “More hyung, fuck yourself on me. Use me, use me, use me,”
It wasn’t long when Matthew started to struggle inside the mask. Breathing too hard, sweat dripping off from every pore, it was soaked and hot and he couldn’t breathe and he wanted to kiss Gunwook. He couldn’t take it anymore.
He grabbed the edge and lifted it only up to the tip of his nose, using his mouth to breathe in fresh air, only to be blocked by Gunwook’s plump lips devouring him.
Gunwook had been waiting for too long, too desperate and hungry for something in his mouth, preferably the hero’s mouth. He didn’t take a second to hesitate when his mask was lifted up and crashed their mouths together. He leaned in forcefully, his hands shifting to the older's waist as he pushed him on his back without breaking the kiss.
It surprised Matthew, Gunwook’s sudden show of strength with his arms and tongue, powerfully shoving his tongue onto Matthew’s and playing with it. Teasing and sucking but still being lovely and wiping the drool down his cheeks. It made Matthew clench again, demanding more of Gunwook’s movements.
When Gunwook finally pulled away, he admired the majestic artwork he had on his bed. A breathless, half-masked superhero, tight and dripping while impaled by his cock. He pounded slow and hard, reaching through the older's depths every time and making him arch impossibly harder. Matthew’s own neglected cock was already leaking steadily on his stomach, painting his smooth, sculpted figure slick white.
“Hyung, you look so beautiful. You feel so per—” Gunwook groaned as he thrusted particularly hard, bottoming out. “Perfect. You’re so perfect. I don’t want to stop. I can’t stop, fuck, I can’t stop, I can’t stop, I can’t st—”
Matthew was fucked out of his wits, his hands tightened on the younger’s sheets as his prostate gets abused by Gunwook’s cock persistently. He’s steadily drooling and leaking out of all his holes– mouth, cock, and ass, and he felt so dirty, so used, so full, so wanted— he doesn’t want him to stop either.
Gunwook leaned down, pressing Matthew’s legs wider and pushing them up to his shoulders as he reached to latch their mouths again. The mask hiding the top half of the hero’s face irritated Gunwook, his hips automatically slamming harder and rougher, ripping out mewls of curses and cries from Matthew’s lips as they shared a breath.
“Gunwook, I’m so close,” The older bit his lip as he tried to control his whimpers, the hands supporting his thighs open shook as his whole body started to tense.
“Come for me, hyung. Let me feel you come on my cock. Let me feel the hero of the city get destroyed by my cock.” Gunwook glanced down at the meeting of their bodies, noticing the rhythmic distension on Matthew's stomach everytime he slams deep. The sight made him dizzy, burying his face on the older's neck and instinctively biting. Matthew shattered right then.
Gunwook’s hips stuttered the moment Matthew violently came, shuddering and arching as he spilled on their stomachs and squeezing on the hardness still moving inside him. Matthew was unapologetically loud and strong, almost pushing off Gunwook if the other man didn’t grab his wrists and pressed them on the bed to rein him in. Feeling Matthew desperately tighten around Gunwook made him see white, his hips moving on autopilot as he chased his release, finishing inside the older while slobbering mess on his marked neck.
The high slowly came to a down, catching their breaths. Gunwook slowly pulled out, both wincing from sensitivity, and followed by Matthew’s hole leaking hot cum naughtily. Gunwook shifted to the side so his weight wouldn’t crash on the older, but still half draped on him as they both settled. He inched close and snuggled his nose to the older's neck, inhaling the same sweet scent that lured him in earlier, now a little more tame and calm compared to the earlier's hot and consuming. Matthew’s hand drifted to the younger’s head and combed his digits to his hair, letting the soothing feeling calm them both down. It wasn’t long until the two drifted to unconsciousness, lulled by the steady warmth and unusual comfort between them, naturally shifting as Matthew, the masked superhero, casually surrendered into Gunwook’s large, inviting arms burying him to his chest.
It was unexpected, driven by his changing body and needs. Gunwook was just a friend and a crush for Matthew, but at that shared moment, he was the masked hero, Spiderman, who needed Gunwook, who pleasantly gave his help. And the mask stayed on, both of them liked it, so he doesn’t really immediately want him to know everything, yet.
