The second and final chapter of this story. I have an idea for a follow-up oneshot I may write, so stay tuned for that I guess.
Somewhere in the school, a clock chimed midnight. Midoriya lie in the school infirmary bed, turning over the day's events in his mind. He'd managed to feign sleep long enough to convince Recovery Girl to phone his parents and inform them that he'd best sleep there tonight, to not stress his body. Really, he just wanted some time alone to think.
What did it mean to date one of your rivals? What does it mean to date at all? Deku had never had a girlfriend before – now he had a boyfriend! It wasn't like he had simply gotten caught up in the moment earlier or regretted accepting his confession. He was just…. What exactly was he feeling right now?
Before he could get any further in running mental circles, a sound at the door shocked him out of his thoughts. 'Who at this hour..?'
The door swung open silently, and Shouto Todoroki's head popped in. "Oh. So you're awake."
"How did you get in here?"
Todoroki shrugged. "Hopped some fences. Picked the lock. Used to sneaking around a lot at home, y'know."
"Right…" Izuku felt himself getting embarrassed at having forgotten what Todoroki's home life was like. Then he suddenly remembered that agreeing to see Todoroki meant running afoul of Endeavor, his father. Deku could imagine that the hulking flame hero probably won't be thrilled at this new development. He felt himself start to go pale – Todoroki noticed.
"You don't have to do this, you know. I'm not begging you. We both have a lot to lose if we get caught…like this. But you more than me. My dad would do anything to cover up anything that could hurt the family reputation or whatever; All Might doesn't seem like that kind of guy." He reached out and gently touched Izuku's cheek. "You already have enough to prove."
And suddenly, things became clear.
Midoriya shook him off. "I don't have anything to prove!" he declared. "I-I mean… I'm still pretty much a no-name anyway, right? But you're a really good guy. S-so if we can make each other happy, and people want to look down on me for being with you, then let them!" Of course he sounded more brave than he really felt, but he didn't want Todoroki to worry about him. And he meant what he said – hearing that Todoroki was also having doubts & fears put his own at ease. He was ready to simply take things one step at a time.
Todoroki gazed down at that round face beaming up at him sweetly, full of feigned confidence. 'An idiot,' he thought, smiling to himself. 'Were they really childhood friends? Kacchan really is a total idiot to not take advantage of this.'
Todoroki leaned in; Izuku squeezed his eyes shut. Gently their lips touched, and Deku's insides turned into butterflies. The moment his lips parted, Shouto's tongue slipped in and resumed its earlier exploration of the younger boy's mouth. Through the intoxicated mush of half-thoughts, it occurred to Izuku that this must be was people called "making out". His face grew even hotter.
He creaked one eye open to see that Todoroki was as flushed as he was, but not out of embarrassment – Shouto had sacrificed thought the moment he'd tasted Izuku's lips again. Now everything was focused on the warm softness against his mouth, and how to get more of it.
They finally broke, panting and hot like wild dogs. Shouto gazed down at Deku, lips swollen, pink flush making his freckles stand out even more, chest heaving against his gym shirt. With a shudder, Todoroki noticed Deku's nipples straining through the thin fabric and found himself gripped with the irrational urge to suck on them like hard candies.
'Thank GOD Kacchan's an idiot!' he thought, covertly swiping away a bit of drool.
"U-um, T-Todoroki…" Izuku interrupted Shouto's leering, lowering his arm from his eyes. "My pants feel…tight."
"Oh, um, yeah. Mine too…" Shouto admitted, suddenly becoming very aware of the firm lump burrowing into his thigh paired with his own flaming arousal.
"Is it okay if we..keep going…from earlier?" Deku barely got the words out, growing redder and redder until he was speaking from behind his hands. He looked like a blushing bride on her wedding night, something Todoroki had to try very hard to keep from observing out loud.
"S-sure…" Shouto desperately fought to keep his voice calm and steady, to hide how much he wanted to rip the boy's clothes off and tear him to pieces. He wasn't sure how, he just knew he wanted to.
With barely suppressed trembling, Todoroki slipped his hands under the fabric of Midoriya's waistband and pulled them down. He bent down and made like he was going to kiss him again, before quickly changing direction and burying his face back into Izuku's neck, leaving his lover puckering into nothingness. Teasing him was going to be fun.
Whatever slight annoyance Deku felt was erased the moment he felt Shouto's teeth on the side of his neck. At first he was unsure what to make of Todoroki dragging his teeth against such a sensitive area, nipping it until he felt sure there'd be strange marks later. But then the love bites turned to gentle kisses and Deku lost the ability to think at all. He had no idea why that area made him feel all breathless & gooey; all he knew was that he'd give the world for it to never stop.
Todoroki leaned back and admired his handiwork – two distinct purple spots stood out against the skin of Midoriya's neck. Any guilt he felt for how the smaller boy would fare at school tomorrow was overshadowed by a twisted pleasure that everyone would see it and know the green puppy had been taken.
He bent down and began trailing kisses from Deku's bruised neck to his collarbone, pausing only to lift his shirt before continuing down to his chest. Two dark nubs greeted him, already erect with arousal and suddenly being exposed to the cold air. Shouto couldn't resist flicking a hot tongue against one experimentally, before taking the entire thing into his mouth.
He was rewarded by a low, guttural moan from Midoriya. The sound turned into a scream when Shouto grabbed hold with his teeth and sucked hard. Todoroki palmed Deku's erection, stroking it through his shorts until he realized the cries had stopped.
A bit concerned, he sat up only to see Midoriya stuffing his face into a pillow, biting it like it would save his life. Todoroki chuckled and slipped his hand underneath the fabric of his underpants, finally coming in contact with Deku's bare arousal. He groaned at the feeling of his bare cock, skin smooth, slick, and hot against his cold hand. It was slightly shorter than his own, and thicker than he imagined.
Midoriya gasped and pressed his face further into the pillow.
"Izuku, what are you doing? You don't have to be quiet around me. I..actually really want to hear your voice…"
Izuku glanced up at Todoroki's bewitched face through his tears. "Can't…. We're at school…" he panted weakly.
'Shiiiit… If he doesn't stop this teary-eyed bullshit, I'm not gonna last long,' Shouto thought, grabbing a hold of his own erection. Despite the lack of attention, he could feel it twitch and weep through his pants.
"It's fine. There's no one around this time of night. We're the only ones here so…be as loud as you want."
This was actually a lie. Nearly everyone knew that security guards patrolled the halls at night, but he was fairly certain no one could hear them in there. Besides, if someone did come and interrupt them, he'd burn them to a fucking crisp.
Midoriya nodded dreamily and let go of the pillow. "You too…" he insisted. Todoroki merely blinked. "I want to see your body, too."
"Oh, r-right." Quickly he stripped off his shirt and pants, leaving them on the floor. He briefly registered how much skinnier he was compared to the smaller boy's wiry frame and made a mental note to train more.
Not that Izuku minded or even noticed. His eyes were too busy scanning the smooth, pale skin, trying not to openly stare at his partner's bulge. Midoriya didn't have the faintest idea how two men made love, but he was suddenly willing to try.
"Shouto…" he panted, "please touch me!"
Todoroki nearly exploded. (They would later find singe marks on the infirmary curtains.)
In a flash, he had Deku's underpants off and across the room. He couldn't stop himself from humming at the sight of his lover's erection swinging free from its cotton prison, leaving a spot of sticky precum where it bounced against his stomach. His own underpants quickly joined Deku's on the floor.
Naked and shivering in the chilly air, they found themselves unable to do anything more than stare at each other's bodies. Not knowing what else to do, Shouto bent over and licked at the wet spot on Midoriya's stomach. It tasted sour, contrasting with the salty musk of his sweat.
He thought about taking the kiss downward and tasting the thick, pink cock throbbing just under his chin, but a moment's hesitation told him that he wasn't ready yet. Instead he trailed up, sucking and biting his way along Izuku's trembling belly and heaving chest, leaving a trail of love bites in his wake.
Izuku spread his legs wider and moaned like he was dying; Shouto's teasing was driving him out of his mind. He couldn't take it anymore – the moment Todoroki came close, he finally grabbed him by the hair and slammed their lips back together. The act knocked Todoroki off balance and the two boys ended up collapsing flat on the bed together.
This time it was Izuku who was aggressive, sucking on Shouto's tongue and biting at his lips until he broke skin. His hips bucked into Shouto's and the feeling of their arousals sliding against each other hit them both like lightning.
"Can we do more of that?" he squeaked.
"Yes, please," Todoroki mumbled, stars in his eyes.
Slowly the boys wove their arms around each other's bodies, crushing themselves flat against each other. They started slowly, awkwardly grinding their hips together, missing more often than not. Eventually they sunk into a rhythm of bucking and grinding, cocks sliding between their hot bodies, voices providing a background chorus of gasps and encouragements.
It was honestly the best thing Midoriya ever felt, sooo much better than when he did it himself at home. The heat and sensation from his lover's body was intense, and listening to him gasp his name with that ragged voice drove him over the edge of sanity. In fact, he was about to…
"Nn! T-Todo… Shouta, I'm-!"
"I-Izuku, this- ohh! *pant* God, this feels..!"
Electric shocks danced up Todoroki's spine; Deku got the familiar pins-and-needles sensation in his fingertips. Both were panting loudly in time, their desperate writhing rocking the bed violently.
Finally he began to orgasm, his gasps turning to whimpers and cries. His nails dug into Shouto's back in a vain attempt to steady the shuddering spasms ripping through his body; ribbons of cum streamed out, coating his entire torso in the warm, sticky mess.
Todoroki kept going, smearing it between them and causing a moist, smacking sound to fill the air.
"Deku, I… Ah..AH!" Watching Midoriya get off had pushed him clear over the edge, and Shouto followed with a loud, wracking orgasm of his own. Deku moaned at the feeling of Todoroki's hot seed spattering against his body. He felt more marked by that action than by the fresh hickeys littering his body.
Exhausted and spent, Todoroki collapsed back onto Midoriya. They rode out their afterglow panting silently, legs tangled up in each other, hearts thumping furiously against each other. Izuku buried his face into Shouto's chest, earning a soft, lingering kiss to the top of the head.
"Todoroki-kun?" Izuku mumbled after a while.
"Yeah?" he responded, absent-mindedly playing with his boyfriend's hair.
"We're still rivals, aren't we?"
"…Yeah. Izuku?"
"Yeah?"
"When we're alone…please keep calling me Shouto."
"…Okay," he grinned, for once glad to be in the infirmary.
