[[This is a de-anon from the Kuroko no Basket kink meme!~ I loved the prompt and I definitely ship the pairing now.]]
Inside the gym storage room of Seirin High School was the only place you wouldn't expect to find this event to be happening. The two young ladies who were kissing and slowly getting more and more naked were from opposite teams; in fact, rival teams. It was completely unlikely for the two to be together. They were supposed to hate each other! However, to Satsuki Momoi and Riko Aida, this only made the secret relationship they had even more enticing.
It had begun as a challenge; a way they could show the other they were better without relying on their teams.
" I bet I'm a better kisser than you!" Momoi had taunted.
" Oh yeah? We'll see." Riko had retorted before throwing herself at the other girl and basically tackling her to the ground. The two had wrestled, until finally they shared their first heated kiss. It was filled with hate and anger, but also lust. It was forbidden, and attractive. They both realized it around the same time: it was love.
After that they would meet a few times a month where they would go out for lunch or an evening walk (which often led to steamy makeouts). After a while, however, they got tired of just kissing and got a little more intimate. It was hesitant at first, especially for Riko who was very shy about her body in comparison to Momoi's more voluptuous one. But after time and much persuasion, they became very comfortable with each other. It had been almost 6 months that they had been doing this when the fateful day came.
It was just like any other day; Touou and Seirin were having an exhibition match. The two girls snuck off to have a quick encounter in the storage closet. It was dark and quiet, and all the equipment had already been laid out for the boys so they weren't likely to be found out.
"Nnng.. Satsuki.." Riko moaned as her partner touched her body. Both were flushed and hot.
"Shhh. Just a little more, Riko~" Momoi said with a whisper. They were almost both to climax, she could tell. All of a sudden, they heard yelling outside the door and slamming. Probably just the boys being reckless again. They decided to pay no mind. However, outside in the gym, Kagami and Aomine were fighting of the basketball for warmup.
"It's MY school, so WE should get it first!" Kagami was yelling.
"Well I'M the better PLAYER. So I should get it first!" Aomine was responding with just as much vigor. Both boys had their hands on the ball, and were squeezing it with all their might. Suddenly, without warning, the ball burst and feel to the ground with a plop. The boys glared at each other and at the same time screamed "I'LL GET ANOTHER ONE!" They raced to the storage room and swung open the door.
Right at that moment both Momoi and Riko came and collapsed ontop of each other, completely naked and exposed. Neither noticed the door being opened or the two boys who were staring at them in disbelief.
"...Coach...Why..."
