Chapter One: Moment (First Kiss)

Izuku watched Mina cautiously as the girl shot him a mischievous grin. She'd come over to his room to study for their upcoming exam, but now they were taking a quick break to let their brains recharge. Looking for a way to make their study session more "fun", Mina had asked Izuku, quite simply, if he was ticklish.

"I don't think so," he answered, trying to dissuade the idea that was no doubt cooking in her mind. It didn't deter her in the slightest, if the widening of her grin told him anything.

"Well now I've gotta find out," Mina snickered, wriggling her fingers in the air playfully.

Izuku took a step back so that his bed was just behind him. She was blocking the door, and thus his only means of escape. "Th-that's not necessary…"

"Don't you wanna know? For science?" She teased gleefully as she slowly closed the gap between them. "What if you meet a villain with a Tickling Quirk? If you know you aren't ticklish, you won't have to worry about them at all!"

He paused at that, his brain automatically considering the possibility. Mina saw his eyes glaze in that way they did when he was thinking hard and seized her opportunity.

Izuku yelped as a pink blur tackled him onto his bed and then her fingers were at his stomach and he was screeching, writhing to escape. Mina laughed, realizing that he was, in fact, extremely ticklish just as she'd hoped.

"M-M-Mina!" Izuku shrieked, scrabbling to get away from her fingers. "St-stop! I-i-it—!"

He was starting to laugh from the sensation, though he was still half screaming as he tried to get away. Mina cackled and sat on him as she redoubled her efforts to make him laugh harder, unwilling to let him escape. "Not on your life! Laugh! Laugh, I say!"

Izuku couldn't breathe as his chest heaved for air, even as Mina's fingers relentlessly sought out new places to try and tickle him. Fearing that he might actually pass out, he made a last ditch effort to escape and grabbed her wrists, then heaved up and flipped them over.

Mina squealed as Izuku ended up on top and after taking a second to catch his breath, he regarded the pink teenager and found her grin to be utterly unapologetic for torturing him.

And maybe he was a little delirious from the lack of oxygen, but he boldly decided the best payback was to get even.

One of his hands pinned her wrists above her head and the other rushed down to her own stomach to tickle her furiously. Mina shrieked with laughter and wriggled, kicking and flailing to get away, but to no avail. Izuku grinned and started to laugh again as he found a particularly sensitive spot just under her ribs that had the girl almost screaming.

"I GIIIIVE!" Mina surrendered, still trying to get away as Izuku momentarily let up the pressure. She gasped to regain her breath with the brief respite. "You…you win!"

"You're not gonna tickle me again?" Izuku asked, still breathing heavy and grinning. He felt light and playful.

"Only if it's for science," she teased, then shrieked as he started to tickle to again. "I'm kidding! Kidding! No more!"

Izuku felt pleasantly warm as he released her hands and giggled with her. They both took a minute to just breathe, recovering the lost oxygen. The excitement faded before too long, but not the undercurrent of energy rushing through his veins.

His eyes were fixed on Mina. Her rucked up t-shirt, still disarrayed from him tickling her stomach. The simple bellybutton piercing he'd never seen before. She'd gotten it with Kyoka a while back. The flush of her cheeks, the prettiest shade of lilac he'd ever seen.

Mina looked back up at him with glowing amber eyes, further emphasized by her dark sclera. She was still grinning, her face flushed and the heaves of her chest gradually settling down as she caught her breath.

Their eyes met and the undercurrent of energy surged.

It was a silent tension, something between anticipation and nervousness. Still smiling, Mina bit her bottom lip playfully. Izuku felt warmth blossom over his face at the sight. The boldness he felt hadn't yet faded away. He leaned a little closer to her.

The warmth between them rapidly grew into a tropical heat. He was keenly aware of her body so close to his own, but he was already hovering over her by the time he felt any sense of hesitation. There was a silent moment between them as he watched Mina's eyes, now so close that he could see the tiniest details of gold flecks, go heavy with anticipation. Their smiles faded somewhat when they were just inches apart, unconsciously knowing what was coming.

Izuku grasped the last of his boldness, leaned heavily on one of his arms, and moved to close the last of the distance, and then all he knew was the warm softness of her lips.

It was awkward at first—the angle he'd chosen wasn't exactly ideal, but they were both too enraptured to really care at the moment. He felt Mina hum against him, the vibration sending electricity through his skin. One of her hands rose to tangle her fingers into his curly hair and she squeezed a little too tightly. Unsure of where to put his spare hand, he ended up wrapping it around her waist and pulling her torso flush against his. Mina gasped and accidentally tugged on his hair again, this time making him yelp.

Realizing she was causing him pain, Mina let him go and the moment was over.

Izuku pulled back and fell away from her to flop onto the bed, his eyes wide and a little shocked as he regained his breath. So that was what all the fuss was about.

Mina started to laugh and his head jerked over to look at her. Every inch of skin he could see on her was flushed lilac, but Izuku was pretty sure that in fairness, he probably looked like a tomato. He felt far, far too hot at the moment.

"Uh," was all he could manage as he tried to speak. Mina only laughed harder at his reaction and twisted her head to look at him. Her eyes were gleaming.

"Not bad, for such a huge nerd," she teased.

Izuku felt the heat of his skin surge and any boldness dissipated completely. He slapped his hands over his face and groaned into them. Was he sweating? God, he was sweating. That couldn't have looked gross at all.

"S-sorry," he whined, his voice muffled against his palms. "I-I don't kn-know why I…"

"Don't apologize," she chastised him playfully. Izuku felt her shift on the bed beside him, but he didn't dare uncover his face. "It was cute."

Cute? He wasn't sure what he'd expected, but that didn't exactly feel like a boost to his confidence.

"Hey," Mina's voice became a little softer, and then he felt two soft hands grasp his wrists to pull them away from his face. Izuku let her, but refused to look directly at the girl who was now leaning over him. "Look at me?"

Izuku reluctantly did as she asked after a few seconds and found himself staring up at Mina's face, shadowed with the ceiling light above her. She had a small smile on her face as she regarded him. "I wanna kiss you this time. That okay?"

Izuku felt his face flush more and jerkily nodded before he could think. Mina's eyes glimmered with amusement as she leaned down, her hands framing his face until she had her lips pressed to his once again. It was still a little awkward, but…

But knowing that she wanted to kiss him just as much as he had wanted to kiss her…made him feel better about the whole thing. Mina pulled back and pressed her forehead to his, the broad smile returning to her face as she giggled. He laughed with her, still nervous, but excited to see what would happen from here on out.

A/N: I know it's late, but I really wanted to write another series for IzuMina week just like I did last year! I'll try to get all the chapters out as soon as possible, so enjoy! More to come!
