It had been a week since Izuku and Ochako had opened their relationship up to their friend-with-benefits Kaina Tsutsumi. Even so, she was always more Izuku's friend than Ochako's. She loved her boyfriend and so she was fine with Kaina. But, the older woman was always more of a competitor than someone she would sleep with, let alone being friends.

Kaina knew this, and so when they all had the discussion for her to move in with them, she spoke in private to Ochako that they would not get in each other's way.

Now today, Izuku was out at a hero conference with UA that would last all day, leaving his two girls home alone with leftovers. They sat in silence eating their microwaved dinner across from one another.

Ochako stared at her plate and leaned forward in her chair, her sports bra and booty shorts hugged her body firmly. It was her day-off clothing and she usually didn't mind it, because she spent most of the day relaxing at home where no one but Izuku could see. Naturally, she felt a bit self-conscious sitting across from the absolute cougar that was Kaina Tsutsumi.

Kaina was only wearing a white bathrobe. Ochako knew this because it was open at least down to the waist. Her large breasts pushed the fabric to the limit and showed off the valley between all the way down to her toned stomach.

"So Izu is gonna be late today, it seems." Kaina sighed as she stuck her fork in the last of her meal.

"Yeah…looks to be that way." Ochako sighed in return, albeit much heavier.

Kaina finished her food, then cleared her throat. "Alright, I thought we had already made this clear."

"Huh? Made what more clear?" The younger woman asked, eyes quickly growing.

"This. When you and Izuku invited me to live here, it was both of you that decided it, right? So why are we acting like strangers?" Kaina asked.

Ochako swallowed. "Well, since you're throwing this on me right now, I might as well be blunt."

"Out with it, sister." Kaina furrowed her eyebrows.

"I can't compete with you!" Ochako blurted.

Kaina relaxed her face, but her mouth slightly gaped open. "Compete with me? I never wanted to compete here."

"With Izuku! Ever since we brought you into our relationship, I just feel so…well, look at you! You're a goddess! You're everything I wish I could be in a woman!" The young brunette declared.

The older woman brushed strands of pink and purple hair from her face. "Ochako, when you both asked me to move in and be a part of this, it wasn't just Izuku I said yes to."

Ochako's heart skipped a beat. It made her freeze up entirely.

Kaina's frown turned into a sly smile. A predator cornering her prey. And Ochako was looking especially delicious now. Such an innocent girl who has no idea what she got herself in to. But Kaina was determined to make her realize just how good this new life will be.

"Izuku's away. Doesn't mean we girls can't have fun ourselves." She said as she stood up and started to approach Ochako's side of the table.

The younger woman shot up from her seat. The natural pink blush in her cheeks grew to a deeper, wider shade of red across her face. Despite her immediate reaction to run, getting out of the chair was the only defensive maneuver she gave as her body froze.

Slowly, the older woman slithered up to the girl, standing at least six inches taller, she looked down on this girl, keeping her smile. She was both warm and welcoming, sly and hungry.

"Ochako…" She whispered.

Hearing her name from her lips at that moment, she knew all too well how she would say "Izuku" in that sultry voice. Maybe it wasn't just jealousy that Izuku was having fun with her, but that she wasn't having fun with Ochako either.

"You need to make it up to me, Kaina." Ochako demanded silently.

With one swift motion, the robe fell. And all of Kaina was there in the kitchen light for Ochako to see. She had seen Kaina naked before. Kaina slept that way with them in their bed. She had seen her taking her boyfriend in bed. But this, this was all new. This was exclusively for her.

Indulging without further hesitation, she jumped forward, pressing her lips into Kaina's.

After a brief and tender moment enjoying a more chaste kiss. They simultaneously relaxed their lips as wet muscles emerged from each other's mouths and began a rough wrestle. After a few moans and caresses, as well as the mindless exploration of tongues, the fight turned more into a rhythmic dance as each twirled around the other. Soaking each other in their individual flavors. Sucking it all up, then spitting it back out to mix again.

Not unlike how they both wanted to do to the rest of their bodies. After several minutes, their legs shook from the lust building up, and becoming too heavy to stand on. They broke away, breathing heavily as more than one strand of saliva stretched from the opening they created.

Then, Kaina grabbed Ochako by her sports bra and pulled as she began to rush toward the bedroom. Ochako quickly followed, almost tripping over many times due to the rough nature of being tugged like a naughty dog on a leash.

They finally made it to the bedroom, and the passion exploded once again as Ochako lunged at Kaina once more. Their mouths squished together as their tongues took turns diving in deep and swishing the drool that acted like alcohol to them, numbing their minds and craving more.

Without even knowing if it was her or Kaina, Ochako had lost what little clothing she had on as she was now rubbing her nude frame against Kaina's on the sheets.

Their passionate kissing continued, but Kaina now had something to play with. Her hands slinked down and squeezed Ochako's ass. The brunette moaned into her mouth, prompting her to spank the fleshy cushions. This turned her moan into a yelp. But it made her shiver and slide her own hands up and down Kaina's sides.

"You can play…Mmm~ With whatever you want." Kaina purred and moaned as she pulled away from the wet kiss. Combined drool had started to pool on her large breasts, acting as lubricant as Ochako pressed her own pair of boobs into the woman's.

They both moaned together feeling their nipples poke and twirl around one another. Feeling Kaina's beautiful body with her own sent vibrations down to Ochako's pussy. It throbbed and leaked against Kaina's thigh. Kaina, sensing this and feeling the same shifted her leg so that Ochako's pussy slid down and lined up with hers.

It wasn't exact, but they had managed to at least align their clits and press together. In that moment, both women sighed and moaned before the younger one on top began grinding their hips. Kaina threw her head back on the pillow in ecstasy. Her hands grabbed Ochako's perky breasts and massaged them.

Ochako purred along with her grunts, smiling at the woman beneath her, giving her so much attention. The way she grabbed her butt, her breasts, the way she kissed her like it was the end of the world… It was just like how Izuku did it. And it made her feel fulfilled. But they weren't finished. There was still one thing left to convince her of Kaina.

Against her brainless lust, she broke the contact between their pussies and rolled off on to her back.

Kaina pouted, before kissing Ochako again as she now climbed on top of the girl. Breaking away, she lifted Ochako's leg and thrusted their mounds together once more. This angle kept them from being more symmetrical, but it was much deeper between their legs that Ochako's back arched.

Kaina scissored her just as rough and passionately as she had kissed her. Their lower lips intertwined and broke apart rapidly with loud squishes as similar fluids dripped on to the sheets and their thighs.

"F-Fuck, Kaina~!" Ochako cursed.

"Ah, O-Ochako you're so b-beautiful~!" Kaina shouted. "So fucking good~"

Any further possible conversation, or even words were replaced with shared "Fuck fuck fuck~!" Fitting, considering that was all they were thinking, and doing.

Their hips crashed together at this angle for a few minutes before they both spasmed and cried out.

Kaina collapsed next to her young lover and spooned her as Ochako panted and turned to face her.

"Do I…need to say anymore?" Kaina breathed.

Ochako shook her head. "You've said enough." She then nuzzled up to the older woman and lazily kissed her again.

Kaina smiled and kissed back. "Just wait until Izuku comes home."

Ochako smiled back. "Now I don't know if I'll be able to."
