Movie night – an innocent enough idea, or so you’d thought. You and him hadn’t had much quality time as-of-late, so you penciled in some quick, low-effort fun.

And, of course, Sero had to be the one to choose the film. You weren’t complaining (much); he had pretty good taste in films. You just hadn’t expected him to pick a movie with…that in it.

Since it was October, Sero had chosen a spooky movie: Corpse Bride. You’d never seen it before, and it seemed interesting. He promised you’d like it, even betting his favorite hoodie that you’d wanna watch it again. You happily took those odds.

About three-fourths of the way through the movie, you were definitely into it. The stop-motion animation was really cool to watch, and the plot had you wondering which way it’d go.

Of course, you also had the world’s comfiest space heater next to you, his arm draped over your shoulder as you leaned against his side. That definitely helped you enjoy yourself.

You were completely relaxed and focused, zeroed in on the television screen. So, when the scene with the spiders came on, you were completely unprepared.

As the folk of the underworld were preparing Victor for the wedding, Victor’s suit was tailored by the spiders. At least six of the hand-sized arachnids crawled across his torso, each repairing some part of his suit.

Apparently, the legs tickled; he jerked about and laughed, squirming as they accidentally tickled him. It wasn’t a long scene, by any means, but it still caught you completely off guard.

Sero felt you squirm, glancing over to see what was going on. You were blushing…? The only thing happening on screen was a quick tickle scene. He saw your foot clench through your socks, and it all clicked. Oooo, I’m gonna have fun with this…

“You’re awfully red over there, hon. What’sa matter?” Sero gave your side a little squeeze, presumably to get your attention. He couldn’t hide his smirk as you jumped, loving the little sound that caught in your throat.

“I-I’m fine. Just…need a drink.” You reached over to grab your drink, only to have him tase your underarm. Squeaking, you back, falling right into his side. He barely had to try to capture you, just wrapping an arm around your waist.

“Hey…” He leaned in, dropping his voice to whisper teasingly in your ear. “Are you ticklish?”

The question somehow both made your blood run cold and your face burn at the same time. When he testingly dragged a few fingers across your stomach, you couldn’t help but giggle in response.

“I’ll take that as a yes~”

Ugh, even his tone was enough to send butterflies swarming in your chest! That wasn’t the only sensation there; Sero began attacking your stomach with his right hand, the left holding you against him. He gave your hip a few teasing squeezes, watching as you bucked and laughed.

“S-SEHEHEHERO!” Wriggling and kicking, you tried to shove his arms away. Unfortunately, the smug hero-in-training was stronger than you, keeping you trapped in his arms.

“Damn, you really are ticklish, aren't cha?” Sero mused, glancing over at the screen. He skillfully hit the remote with his toe, pausing the movie so only your laughter could be heard. He loved the sound of it: raucous, flustered, and utterly adorable.

Actually, your laugh sounded…really different. It was less reserved; you didn’t exactly have the choice to hold back, after all. The sound was free, helpless, and oh-so-happy. It brought a slight blush to his cheeks, making him huff.

“You’ve been holdin’ out on me, you brat!” The tape-quirked boy playfully growled, resting his head on your shoulder. He wasn’t sure if it was flustering or not, but it was comfy. “Where’s this pretty laugh been, huh?”

“I-IHIHIT’S NOHOT PREHEHETTY!” You denied the claim, kicking your feet against the worn cushions of his couch. It wasn’t helping you escape in the slightest, but it helped you not to lose your mind.

“I’m sorry, what did you just say?”

Suddenly, he stopped, giving you a moment to catch your breath. Fuck, that tone…he didn’t sound happy. You just huffed, shrugging.

“You don’t get to lie to my face. That has consequences.”

Before you could ask what he was talking about, he activated his quirk. Your wrists were taped together and hoisted above your head, the tail of the tape sticking to the ceiling. You were stuck to wiggle helplessly, back facing your attacker.

“I didn’t lie!” The annoyed huff told you that reasoning wasn’t gonna work. Begging it was, then. “W-wait, wait, Sero! I’m sorry!”

“Too little, too late. Sing for me~”

With that, the real attack began. Sero let his right hand attack your armpit, the other clawing at your stomach from behind. All the while, he whispered little teases in your ear, flustering the shit out of you. It was hardly fair, but you couldn’t really complain properly through your cackles.

"You have the prettiest laugh on Earth, hon. I'm not gonna let you forget it~"

As you squirmed and thrashed, your top began to ride up. It exposed your belly fully, and Sero was more than happy to take advantage of that.

“Don’t mind if I do…” He dragged his short nails across your bare midriff, loving the feeling of your quivering belly beneath his fingers. “I could do this aaaaall day, hon~”

You were losing it, thrashing and twisting to try and get the tape off. It held diabolically strong, leaving you trapped under Sero’s evil fingers. Eventually, you hit your limit, letting your head hang forwards.

“S-SEHEHEHEROHOHO! NOHO MOHOHOHORE!”

He begrudgingly stopped, sensing you had reached your limit. The tape was removed, and he pulled you back against his chest to cuddle. Utterly exhausted, you complied without a second thought.

“Geez, I don’t think I’ve ever met anyone as ticklish as you.” Sero chuckled, gently rubbing the stomach he had just finished tormenting. You just groaned in flustered annoyance, burying your face in his warm chest.

“Shut up, Hanta.” You used his first name to let him know he was pushing it. The head pats you received were close to compensation, but he had a long way to go.

Glancing over, you finally remember the movie the two of you were watching. You were about to fall asleep, so finishing it would have to wait until tomorrow. Actually…

“Hey, since we didn’t actually finish the movie, I can’t watch it again. I won the bet.” Watching his expression go from confusion to despair felt extra gratifying in that moment. He sputtered, trying and failing to come up with a reason to deny you. You’d found a loophole.

“Damn it…fine. You can have my Kuromi hoodie…brat.” You stuck your tongue out at him before cheering; you’d been after soft purple article for months.

Yeah, he was never gonna see that hoodie again…
