Ymir doesn't mean to follow Christa out after dinner. Or to end up helping Sasha. Or to eat breakfast with the girl the following morning.

"Thank you again for bringing Sasha back to bed last night."

Ymir forms a half smirk before taking a swig of water. "Don't mention it."

"I owe you one."

The brunette turns to face her. "You were helping her out of the kindness of your own heart, right? So don't worry about it." Ymir winks.

Christa seems too busy trying to figure out the implications in her words than the wink itself. Ymir, however, quickly shoves food in her mouth, trying her best to appear nonchalant.

She glances at Christa, with her porcelain skin and sky-blue eyes, soft-looking lips-

Soft?

As if she can read her thoughts, Christa licks her lips, slowly.

The blonde faces Ymir. "Am I good?"

Ymir blinks. "What?"

"Do I have any food on my face?"

"No, you're perfect." A slight panic runs through her. Shit.

She swears she sees Christa's cheeks redden for a second as the blonde stands up. Ymir places her attention to her food.

"Uh, Ymir?" she asks.

"Yeah?" the freckled girl angles her body so she's facing Christa's direction. Which happens to be her backside.

"Can you make sure the straps are on tight enough?" she requests, sounding too innocent for this to be out of genuine concern. "I don't want them to come undone." she adds.

"S-sure." Ymir swings her legs over the bench, so they're in a more comfortable position. Hunching over, she fumbles with the strapping on the back of Christa's knee.

"Higher." Christa demands, shyly. Ymir's grateful she's facing the other way, her face is hot as she fiddles with a buckle. A buckle that happens to be right below Christa's butt, her very nicely shaped butt.

Ymir can't deny she has the slightest urge to slap it.

"There- all clear."

"Thanks!" Christa whips around, looking down at her. "I think that takes care of the favor I owe you." Christa winks. Before Ymir has a chance to say anything, Christa walks off with a slight bounce.
