"Happy birthday, Kassy!" Matt burst into the house, taking her by the face and kissing both her cheeks.

"Thank you, Matt!" she smiled as he handed her a present.

"Just a little something." he said.

She opened it up, and smiled as it revealed itself to be the newest book by her favourite erotica author.

"Cheeky boy." she smacked his cheek, gently, before hugging him. "Thank you."

He hugged back. "You're welcome. What are you doing today?"

"Fuck all." she smiled. "Veronica's mom has the kids, so Shiro and I are just chilling. It's been our first chance in weeks."

Matt nodded, and smirked. "You gonna get a little frisky? Get in your birthday suit?"

She shook her head. "Shut up, Matthew."

Matt shrugged and sat down. "Guess I'll be chilling with you then."

Kassy sighed, grabbing some wine that Lance had given her that morning. Shiro joined the two, and they started day drinking.

Well, a few hours passed, and Matt ended up... emotional. The emotion he was feeling was horny.

Shiro glanced over at him, seeing his quiet face staring downwards.

"Hey, Matt, can you get more wine?" Kassy asked. Matt, glanced down at his hardened cock, and blushed slightly, knowing how obvious it would be should he stand up.

"No, thanks." he said.

Shiro glanced down, as did Kassy. "Oh." Kassy giggled. "Someone's got a little problem."

Shiro laughed then, drunkenly giggling, the 3 glasses of wine going straight to his head. "It's not that little."

"Shiro, you naughty man!" Kassy snorted, smacking his shoulder gently.

"Well, you're the birthday girl. Surely you should compare us." Shiro winked.

Kassy stared at him. "Well, we're learning of some hidden depths here, aren't we? What do you say, Matt? Threesome?"

Matt stared at them. "Wait, legit?"

Kassy shrugged. "Sure thing, babe."

Matt proceeded to press his lips against Kassy, slipping his tongue into her mouth.

"Wow, someone's been anxious for this." Shiro said, waiting a few moments. "Okay, my turn."

Shiro proceeded to grab Matt by the hips, running his hands up and down his chest. Kassy, on her hands and knees, cupped his face, gently kissing him again, as Shiro worked his pants off him, taking his length in his mouth. Matt, under Kassy's lips, moaned softly.

"I know, sweetie, that feels good, doesn't it?" Kassy murmured, her voice soft and velvety as she ran her hands over his face and through his hair. "Aren't you being so good?"

Matt's hips bucked. "Shiro, I-"

Kassy took him by the shoulders. "You cum, and I'll hurt you." she hissed in his ears. As he approached, Shiro pulled off of him.

"Hey!" Matt panted. "I was close!"

"If you finish now, you have to watch Kassy and I have sex for the rest of the day." Shiro said. "I did it for your own good."

"Speaking of Kassy..." Matt turned to Kassy, glancing her clothed form up and down.

"Oh, right." Kassy took her shoes off, then her socks, being as slow as possible. Then, her leggings, being purposefully as slow as possible to show the true stars. What Matt really wanted to see.

Matt watched as she lifted her shirt off, gazing at her cleavage, breathless as the bra came off.

"You're... you're like a goddess." he mumbled. She smirked.

"Go on, then, sweetie. Have a feel."

Matt slowly brought his hands up to her chest, stroking over the soft tissue, rubbing her nipples gently, bringing his face into them, giggling and hyperventilating the whole time. Kassy exchanged a glance with Shiro, and smiled slightly.

She took his shoulders again, and pushed him to the floor, slipping herself onto his stiffness. Matt moaned again.

"You're vocal, aren't you?" she bit her lip, and slowly started to ride.

After a couple of minutes of the slow, steady motion, Matt managed to flip, so Kassy's legs were spread in missionary, his manhood slipping in and out.

Shiro hovered above her head, and she reached up, taking his length in her hands, stroking it as he made noises of pleasure.

The front door opened but none of them heard.

"Happy birth- oh, fuck!"

The three froze, looking up at Hunk.

He looked at the scene. Kassy with her legs wide open, Matt fucking her, her holding Shiro's hard cock.

Hunk was also frozen, mouth hanging open, dropping the bags he was holding.

Kassy blinked. "Hunk, I- I'm not a bottom."

Hunk came back to, screamed, and ran out.

Kassy glanced at the two men, inhaled and exhaled, and spoke again. "Shall we continue?"

"What the hell is it with Kassy and Shiro never locking their door?" Hunk went home.

"Did you walk in on them again?" Shay asked.

"Yep. And they had a special guest with them, too."

Shay cocked her head. "Pardon?"

"They're having a threesome."

"Whats that?"

"Balmerans don't do threesomes? Like, 3 people... making love?"

"No? I didn't know that was a thing." Shay said. "That's a strange idea."

At that moment, Romelle entered with Allura. "Guys! I'm showing her off. Look how cute her tummy is!"

"Romelle, you know what a threesome is, right?"

"Hm? I learned when I came to Earth cos I've been in a few. It's not a thing on Altea, though."

"What's a threesome?" Allura asked.

Matt sighed contentedly.

"That was the best birthday present ever." Kassy said, exhaustedly.

"Kassy? I'm over you. I can move on!"

Shiro clapped. "That's my boy."

"I'm gonna go call Daisy right now!" he grabbed his clothes and ran off.

Kassy cleared her throat. "So... we won't be doing that again?"
