Ryoko laughed loudly as she reached the end of her morning run's route and turned to look at where Sawada was still lagging behind, huffing and puffing and struggling to make the last stretch of the road.

"EXTREME!" Ryoko shouted at the top of her lungs, just because she could and because she liked saying her favorite word, and to encourage Sawada to complete the run.

And it worked! Ryoko grinned widely when Sawada raised her head to stare at her with an intense look in her narrowed eyes before she redoubled her effort.

A couple of minutes later, Sawada finally reached Ryoko, panting and sweating, bent over to brace her hands on her knees.

"You did great Sawada!" Ryoko patted Sawada on the back heartily, and Sawada almost toppled over; hmm, maybe Ryoko needed to take Sawada with her to more training exercises.

Sawada raised her head and sent that same intense look Ryoko's way and Ryoko sent back a thumbs-up.

"See you at school, Sawada!" Ryoko shouted and turned to head back to her house for a shower.

.

(Tsuna straightened up and glared harder at the back of her retreating self-proclaimed rival. Clenching her fists, she resolved to do better during the next morning run.)

.

"That was EXTREME, Sawada!" Ryoko raised a fist to Sawada who stared at her with wide-eyes before she turned to look at the groaning bodies littered on the ground.

"But I-" She started, clearly confused, and Ryoko dropped her fist, the wide grin on her face turning into a gentler thing, less bright, less blinding, and Sawada stared at her with wide-eyes.

"You were defending yourself, right?"

Sawada nodded mutely.

"If they wanted to get into a fight, then they should know they need to be strong enough to win it, right?"

Sawada nodded again, this time slowly.

"Then it's their fault for not being extreme enough to handle it, not yours!" Ryoko's mouth stretched into its usual wide grin again, "Anyway, we should run before Kyoko finds us and gives us the Disappointed Look." Ryoko shuddered while Sawada continued staring at her in mute shock.

"Come on! What are you waiting for?!" Ryoko grabbed Sawada's shoulder and jogged away, pulling the other girl with her, "Let's hurry!"

"Fine!"

.

(Tsuna inwardly grumbled; maybe Sasagawa Ryoko wasn't so bad.)

.

Ryoko rolled over on the bed and stared at Tsuna, who was lying ramrod straight next to her, with her hands firmly gripping the edges of the bed sheet and clutching it to her chest while staring vacantly up ahead.

"Tsuna?"

Tsuna's eyes snapped towards her and her face flared red, "We! Had! Sex! I can't believe we had sex!"

"Did you not want to?" Ryoko started cautiously, trepidation filling her at the thought that maybe she-

"It's not that! I- I- I didn't mind at all actually-!" Tsuna raised the sheet to cover her mouth as she mumbled something inaudible.

Ryoko cocked her head to the side in confusion, and Tsuna pulled the sheet down to speak clearly.

"I said that I… umm. I liked it. I. Don't mind doing it with you again… if you have no problem with that of course!" Tsuna's voice rose into a high pitch at the end, her blush intensifying, and Ryoko smiled before she flopped on top of Tsuna, who squeaked.

"I have no problem whatsoever." Ryoko stared down at Tsuna, "Does that mean we're dating?"

Tsuna's eyes almost popped out of their socket before she regained her composure (she was still blushing, though), and sniffed imperiously, "I believe so. But don't think I'll go easy on you just because we're dating now."

Ryoko threw her head back and laughed.

.

(Tsuna pouted; why did Ryoko have to be so hot?)
