Katsuki was deep asleep after a long night of patrol. He felt the sheets flutter near his hips, the cold air crept over his bare body as her soft, padded fingers grazed over his thigh. He kept his eyes closed, pretending to be asleep, letting her continue.

Ochako’s warm, wet mouth teased the head of his dick as it hardened in her hands. Katsuki groaned and squirmed.

“Happy Birthday, Katsuki.” Ochako grinned, knowing he was awake. She took him further into her mouth.

Katsuki groaned again and grabbed the back of her head “Shit, Cheeks!” His voice was still husky with sleep. “This is how you’re starting my birthday? Can’t fucking wait to see what your little round ass has in store for the rest of the day.”

Ochako looked into crimson eyes with a devilish smile. “You’re going to love it.”

“The fuck is this, Star Shine?” Katsuki called from their living room later that morning.

“Open it!” Ochako pranced down the hall excitedly, clapping her hands.

Katsuki cocked a brow at his wife but opened the brightly wrapped box. He tore into the garment box and found a delicate pink scarf with a golden ticket.

-HAPPY BIRTHDAY, GROUND ZERO-
Enjoy the evening with dinner and
a threesome with Uravity and guest

Katsuki dropped the box. His jaw went slack with shock as he gawked at his giggly wife.

“What the actual fuck?”

Ochako ran her hands over his firm chest. “I got you something special for your birthday.”

“A threesome?” Katsuki shook the ticket in her face. “I asked for a Switch! This wasn’t what I had in mind, Cheeks!”

Ochako shrugged. “You’ll like her. I did.”

Katsuki’s eyes felt like they were going to fall out. “What?”

“She’s gorgeous! I had a meeting with her a few days ago to arrange everything. She’s a professional sex coach that occasionally joins her clients.” Ochako smiled brightly.

“A sex coach?” His lip curled into a little sneer. “We need a fucking coach now?”

“She mostly does couples coaching. Like she watches couples have sex and helps spice things up,” Ochako shrugged. “She’s excited to work with us!”

“There’s nothing wrong with our sex life, Round Face.” Katsuki growled. “I just fucked you in the locker room of the agency yesterday. Twice! That was after eating that gorgeous pussy of yours on your desk during lunch.”

Ochako gave him her puppy dog eyes. “This is something we haven’t done though,” She pouted.

“Is this my birthday or yours?” Katsuki pondered.

“I promise you’ll enjoy it! She’s coming to the party with us too.” Ochako kissed his neck just under his chin.

“Fucking excuse me!”

“Loosen up, Kitten!” Ochako laughed. “She won’t do anything you’re not comfortable with. If you really don’t want to do this, I’ll call and cancel.” Ochako frowned.

Katsuki sighed. “You know I don’t need anybody but you.”

“I know that, silly!” Ochako smacked his side playfully. “This is just for fun.”

Katsuki pulled her close and hugged her tight. “You know I don’t like to share.”

The couple stayed home and enjoyed the afternoon alone just as Katsuki had requested. To Katsuki’s protest, Mitsuki had organized a fancy dinner for the hero’s 30th birthday that evening. Ochako informed him that their new “friend” would be there when they arrived.

He grumbled as he got ready and went to the living room to wait for his wife.

Ochako slipped on her strapless, skintight gown. The pale orange dress hugged all of her curves just right with a slit that rode up her thigh and stopped just below her hip.

He was going to love it.

She admired herself in the mirror before sweeping her hair back into a bun with little wisps flowing around her face. She went to her closet and put on her nude stilettos and took one last glance in the mirror.

“Cheeks, we gotta go!” Katsuki called from the hall.

There was a knock on their door. Ochako heard him answer and the mailman greet her husband kindly.

“Hi, sir! Here’s a package for you guys. Mrs. Bakugo told me today was your birthday. Happy Birthday, sir!”

Katsuki clicked his teeth and mumbled his thanks before slamming the door.

“Katsuki, you should be nicer to that boy. He admires you.” She scolded as she strode down the hall to see what had arrived.

Katsuki glanced over his shoulder at his wife. He had to do a double-take. He let out a low whistle, his eyes drinking in the sight of her. He tossed the mail on the couch and loosened his tie as he stalked over to her.

“Holy fuck!” He groaned, grabbing her face between his hands, and pulling her against him for a kiss.

Ochako giggled against his lips. “Katsuki!” She backed away. “You just said we need to go.”

“Yeah, back to the bedroom.” He tried pulling her back to the hall. “Or right here on the goddamn floor, but that dress needs to come off.” Katsuki kissed along her jaw and down her neck.

Ochako’s head was swimming with desire like always, but she knew they needed to go.

She pulled away further, just out of his reach.

“What’s in the box?” Ochako tried to shake off the feeling by distracting them both.

“I don’t fucking care,” Katsuki pouted.

“Fix your tie, baby,” Ochako stated offhandedly as she picked up the box addressed to the both of them. She took it to the kitchen to cut the tape and opened it up.

Inside was a black velvet bag and lovely handwritten a note.

—I am looking forward to our evening together. This is for your enjoyment to enhance the mood. Please wear it to the party and let me know how it works for you. I will see you there.

Happy Birthday, Mr. Bakugo.
-Ms. Yaoyorozu—

Ochako excitedly tore the bag open to find a tiny pink vibrator with a remote control.

“Is that what the fuck I think it is?” Katsuki exclaimed over her shoulder.

Ochako turned to him, the excitement apparent in her big, brown eyes. “Can I?”

“Go put that shit on, Cheeks.” he gave his toothy side smile.

Ochako clapped and bound to the bathroom after handing him the remote. She secured the tiny vibrator in her panties and stepped out of the bathroom.

A strong vibration shot through her causing her to stumble against the door frame of the bathroom.

“Katsuki!” Ochako scolded.

Katsuki’s rich laugh echoed through the house. “I wanted to see how strong the damn thing is.”

“So, you put it on the highest setting straight away?” Ochako scowled. She smoothed down her dress and steadied herself on her heels.

“That was only halfway, Star Shine.” He grinned again.

Ochako’s eyes went wide. “Oh shit.”

Katsuki put his arm around her waist and led her to the door, tucking the remote in his pocket. “Maybe this will be fun.” He hummed in her ear with a kiss.

Katsuki and Ochako entered the restaurant. He had one hand
on the small of her back, his other hand in his pocket. When they were greeted by the maitre d’, Katsuki turned the vibrator on low. He smirked when Ochako’s voice squeaked as she spoke.

“There’s a guest who requested to meet with you before you
enter the dining room.” The man informed as he led them to the party room. “She said her name is Yaoyorozu.”

“Oh, yes. A dear friend of ours.” Ochako yelped at the end with a little jump when he turned up the pulsation.

“Are you okay, Mrs. Bakugo?” He asked, brows furrowed with concern.

Ochako subtly elbowed Katsuki, smiling brightly. “I’m okay, thank
you for asking. My shoes pinch a little.” She turned to her husband and hissed under her breath, "You're such an asshole."

"This was your idea, Cheeks." He kindly reminded her.

The pair rounded the corner to see a lovely raven-haired woman standing in front of the double doors. She was tall and curvaceous, wearing a
deep crimson gown. Her long, dark hair flowed over her shoulders in soft waves

Ochako greeted the woman with a kiss on the cheek. The maitre d' wished Katsuki a happy birthday and went back to his stand.

“Good evening, Mrs. Bakugo. You must be, Mr. Bakugo.” The
woman greeted professionally with a handshake.

Katsuki gave her a quick shake before taking his hand back quickly. “I trust that you received my gift?”

Katsuki reached into his pocket and turned it up again. Ochako closed her eyes and took a deep breath before answering.

“We did. Thank you so much. I believe Mr. Bakugo is enjoying it a little too much though.” Ochako glared at her husband.

Momo covered her mouth, trying to hide her amusement.

“Yeah, thanks for this.” Katsuki grumbled. “We call you Yaoyorozu or what the hell?”

"Oh, please call me Momo." The woman's stunning smile left them both weak. "This is meant to be fun, Mr. Bakugo. I'll be texting both of you throughout the evening to, shall we say, make things a little more exciting?"

"What the hell are you going to text us?" Katsuki sneered.

Momo shrugged and looked at the floor before meeting his ruby gaze. "I'll ask you things about your partner. These questions will be about intimate details, so please be as open and honest as possible.”

“This will all come in to play later this evening."

Katsuki shifted his weight nervously. If he was being honest with himself, Momo was stunning. She didn't hold a candle to his wife, but Ochako had made one hell of a choice. He could tell Ochako thought so too.

He noticed the way his wife's eyes danced over the other woman's figure.

"May I just say that you two make a divine couple?" Momo fawned as admired the couple.

"Obviously, I've seen you both in the media. I admire your hero work and appreciate what you do for society. You're both always so lovely in photoshoots, but you're absolutely gorgeous in person. Both of you."

Ochako's already pink cheeks began to darken.

"Thank you, Momo. That's very sweet of you to say."

"I think this is going to be a great evening for the three of us." Momo grinned, her tone holding more than just polite pleasantries.

She took a step towards Katsuki, resting her hand on his chest. "Just relax." She whispered when he tensed under her touch. "Watch Ochako."

Katsuki looked at his wife and did his best not to flinch away when she slid her hand in his pocket.

She found the remote and turned it up, causing Ochako to yelp.

"Remember that sound, Katsuki." Momo purred in his ear. "We'll both be enjoying more of that later."

Momo withdrew her hand just as the double doors opened, and Katsuki's mother appeared.

"There you are!" Mitsuki exclaimed. "We've been waiting- who are you?" Mitsuki stopped her rant to eye the mysterious woman.

Ochako took Momo's arm. "This is Miss Yaoyorozu. She's a dear childhood friend."

Katsuki turned the vibrator off and tried to fight the stirring in his pants. His mother's constant yelling helped.

"Get your asses in here!" She led them to the party room.

Ochako turned and gave her husband a coy little wink. "Have fun, Katsuki."

He patted his pocket. "Oh, I fucking plan to, Round Face." He flashed his cocky, toothy side smirk, leaving her weak.
