MHA: Mizumi's Story

Christmas

3rd Person
In an attempt to escape his classmates and their holiday decorating, Shinso comes over to Class A's dorm to find them also decorating for their own Christmas party. He smiles to himself as he silently stands in the doorway and watches both of his partners working together with their classmates. He's happy to see how well Mizumi and Kaminari work together after their little lover's spat not too long ago. They get along well with their whole class, and Shinso finds himself relaxing as he watches over his beloved partners.
He watches with interest as a pile of holiday stuffed animals is put on the floor, and his girlfriend lights up at the sight. As soon as she is left alone with the pile, she looks around to see if anyone is watching her, then jumps on top of the pile like a little kid jumping into a pile of leaves in the autumn. A few of her friends turn their heads as she starts giggling like a little kid, and they laugh along with her.
"Aw, my favorite little cuddly toy in her natural habitat~ but who needs stuffed animals when you have this little cutie?" Kaminari flirts as he picks Mizumi up.
"Sparks, don't tease me like that, you're gonna make me blush..." Mizumi whines into Kaminari's shoulder as she clings to him.
"But you're so cute when you blush~" Kaminari kisses the top of Mizumi's head and carries her over to the couch, sitting down with her in his lap.
"Kaminari, can you help with the tree?" Iida asks, startling the couple out of their cute moment. "Yeah, okay..." Kaminari sighs and sets Mizumi down, kissing her forehead. "I'll be right back, my Little Spark."
Mizumi pouts as Kaminari puts her down, but nods as she watches him walk away.
"If I didn't know any better, I'd think you were on the verge of going into littlespace for a second there," Shinso says from behind her.
Mizumi jumps a little as he startles her, then lights up at the sight of him. "Hitoshi! How long have you been watching us?"
"Only a few minutes. I think your classmates have gotten so used to me that they just ignore me now," Shinso says. "Nobody jumped up to greet me when I walked in."
"Well, in that case..." Mizumi giggles and pounces on him, then kisses all over his face. "Welcome back, my love~"
Shinso chuckles and gently pushes Mizumi away from his face, not wanting to show his flustered expression to anyone who might be watching the interaction. "Okay, okay. That's enough. Down, Kitty."
Mizumi sticks her tongue out at him, but obediently sits calmly next to him. "Yes, Toshi."
"Good girl~" Shinso smiles and puts his arm around her as he leans back, relaxing as he turns his attention back to Kaminari.
"Hey, Toshi!" Kaminari grins as he notices his boyfriend. "Good to see you, man!"
"Hey there, Denki. I should be surprised you and Siren didn't see me come in, since you were so caught up in each other~" Shinso teases.
"H-hey, be nice! It's not my fault we have the cutest girlfriend in the world!" Kaminari protests.
"Yeah, I guess you've got a point there. Our girl is the most wonderful person in the world, and we are very lucky to have her in our lives~" Shinso smirks as he gently pats Mizumi on the head.
Mizumi squeals and flops over onto her side, hiding her face in her hands to cover up her flustered expression. Both boys, along with a handful of witnesses laugh at her reaction, making her want the floor to swallow her whole as she get even more embarrassed.
"Hey, Little Spark. Check this out!" Kaminari calls to Mizumi, trying to make her feel better.
"Hm?" Mizumi slowly lifts her head to see Kaminari as he picks up a string of lights. He puts the plug in his mouth and uses his Quirk to light them up, grinning proudly as he makes his friends and partners laugh. His superior electrical currents make the lights even brighter than they would have been if they were plugged into the wall, and he takes a small bow to the room as his classmates applaud him after he spits out the plug, making the lights stop glowing.

A few minutes later when Mizumi isn't looking, Kaminari puts mistletoe in the doorway she's standing in and clears this throat dramatically, trying to catch her attention.
"Hey, Little Spark~"
"Yes?"
Kaminari points above her head, making her look up. "You know what that is, don't you?"
Mizumi blushes deeply as she notices the small plant dangling just out of reach. "Mistletoe?"
"Mhm...and you know what it means?" Kaminari leans closer, wiggling his eyebrows flirtatiously.
Mizumi nods slowly and blushes even brighter as her boyfriend pins her to the wall. She whimpers happily and wraps her arms around his neck as he kisses her, immediately slipping his tongue into her mouth. They both moan into the kiss, catching the attention of a handful of their classmates. Some of them blush and look away, while others coo and whoop at the romantic and slightly erotic display.
"Kaminari! Please keep things age appropriate!" Iida scolds, waving his hands and chopping the air as he comes between the couple. "This is no place for your perverted displays! Save it for your private time!"
Mizumi giggles and gently hugs Kaminari, clinging to his side as he puts an arm around her. She reaches up to plant a gentle kiss on her boyfriend's cheek to make up for the interrupted moment before offering a guilty smile to the class rep. "Sorry, Tenya. Is this any better?"
The class rep sighs and shakes his head in exasperation. "I shouldn't have to step in and separate you every time you get overly affectionate."
Kaminari grins proudly. "I'm sure you'll understand if you ever fall in love. It's kinda hard to keep your hands to yourself when you're just so obsessed with your partner~"
Iida rolls his eyes and walks away as the couple calms down, agreeing to keep their steamy makeout sessions private.

It's not long before Kaminari has the idea to kiss Shinso under the mistletoe as well, but doesn't know how to get his boyfriend's attention without making it obvious. He tells Mizumi about what he wants to do, and she helps him come up with a strategy.
"Hitoshi, can you come over here for a second?" Mizumi calls him over.
"Yes, Kitty?" Shinso says as he gets up from the couch and walks over to her.
"Denki wants to show you something~" Mizumi giggles.
"Uh, okay?" Shinso watches her suspiciously as she walks away.
"Toshi~" Kaminari says flirtatiously. "I have something for you~"
"Hm?"
Kaminari stands on his tiptoes to kiss Shinso, attempting to pin him to the wall like he did with Mizumi not too long ago. Shinso smirks and flips Kaminari, pinning him to the wall instead. Mizumi watches happily from the other side of the room, proud to know that her boys are getting along and being affectionate with each other with very little of her influence.

On Christmas morning, shortly after their respective class parties, Kaminari and Mizumi have a very special present for Shinso. Kaminari enters 3B's dorm building, dragging a large box.
"Special delivery for Hitoshi Shinso~" Kaminari grins proudly as he places the box at his boyfriend's feet. "This one is from both me and Siren."
"Where is she?" Shinso questions.
Kaminari smirks. "She had something to do, but you might want to open that box ASAP."
Shinso carefully unfolds the flaps of the lid, then immediately jumps back, letting out a startled grunt as a familiar cute girl pops out, wearing a cat girl outfit that shows off her curves and best physical assets.
"Surprise! It's a Kitty!" Mizumi giggles.
Kaminari laughs as he watches his usually calm and collected boyfriend struggle to compose himself after that surprise. "Merry Christmas, Toshi~ do you like your gift?"
Shinso chuckles as he shakes his head in disbelief. "I swear, the two of you will be the death of me..."
Mizumi continues to giggle as she steps out of the box, then stops suddenly as she notices something. "Hey, wait. There's actually something in here..."
"Hm? What is it?" Shinso asks.
Kaminari watches with interest as Mizumi bends over, deliberately showing off her butt to both of her boys as she grabs the piece of paper from the bottom of the box. "What does it say?"
"For Hitoshi Shinso. Congratulations on winning the lottery, you are officially the richest man alive," Mizumi reads out loud. "But not with money, because this box contains a lifetime supply of love and affection~"
Shinso struggles to contain a blush as Mizumi turns to him with a seductive smirk on her face, then his eyes widen as she gives the orders to Kaminari.
"Denki, get him!"
Before Shinso can react, both of his partners pounce on him, effectively pinning him down as they attack his face with dozens of kisses. Kaminari and Mizumi giggle as they aggressively smother their man with love, happily snuggling and nuzzling him as he gently pets their heads.

Later that same Christmas day, Shinso and Kaminari come up to Mizumi with a present for her.
"Here, Kitty. This one is from both of us," Shinso says.
Kaminari grins as the boys watch their girlfriend carefully unwrap the present. Her eyes widen as she recognizes the cover of a book she had been wanting for months.
"No way...you didn't..." Mizumi says breathlessly as she admires the beautiful artwork on the cover.
"We did. Toshi bought the first one, and I bought the sequel~" Kaminari says excitedly.
"Sequel?" Mizumi lifts the book on top to reveal a second book in the same wrapping. "Thank you both so much for these...but how did you know I wanted them?"
"Remember when we took you on a date to the bookstore a few weeks ago? We noticed the way you looked at these like you wanted them really badly, so we went back for them later that same day," Shinso explains.
Mizumi's eyes fill with happy tears as she clutches the books to her chest. "I love you so much. Thank you for paying attention to me, both of you~"
