Miscalculation by Halrloprillalar
Prince of Tennis, InuTez, PG-13, 400 words.
Be careful what you ask for.
Inui was two minutes early for their meeting. "What is it, Tezuka?"
"I need your help." Tezuka pointed to the chalkboard. "I'm using the formula but not getting the expected result."
Inui bent over Tezuka's homework paper. "You've copied it down incorrectly. It's 5x, not 3x. So all your calculations are off."
"It's not like you to make such a simple error, even though the writing on the board is untidy." Inui said. He adjusted his glasses. "Perhaps you are somewhat off-balance today."
"Perhaps," Tezuka said.
"This is a good opportunity." Inui moved closer to Tezuka, much closer than usual. Tezuka took a step backward. Inui took a step forward. Tezuka moved backward again, but Inui moved with him and all at once Tezuka's back was against the chalkboard and Inui's arm was around him.
"Inui." Tezuka got his hand onto Inui's chest and pushed, but Inui was solid as a tree trunk. "Is this about my data?"
"This is an unrelated matter." Inui brushed his fingers over Tezuka's cheek. "There is only a 2% chance that you will call for help," Inui said. "Because you won't want anyone to see you in this situation." He smiled what Momoshiro called "Inui-senpai's Evil Smile #5" and then he kissed Tezuka.
Tezuka's head banged against the chalkboard. Inui's hand was on his face, holding it still. Inui's mouth pushed until Tezuka's lips parted. Inui slid his tongue along Tezuka's, chasing it when Tezuka moved it away. And then he did it again. And again. Until Tezuka's mouth was watering and his knees were shaking and it was only the iron in his soul and Inui's arm around his waist keeping him from sliding to the floor.
Then Inui let him go. Tezuka wiped his tingling mouth with the back of his hand. "Inui."
"Don't worry, Tezuka. I won't try this method of attack again." Inui smiled again. "It won't work if you're expecting it." He left the classroom.
Tezuka sat down at a desk and waited. He couldn't leave until his breathing returned to normal. He closed his eyes and swallowed, remembering the weight of Inui's body pressing against him, the heat of Inui's mouth. Then he crumpled the homework paper into a ball and tossed it into the trash. He smiled.
Asking Fuji's advice had been the right thing after all.
