Proper thanks

"Come on Sis," Makoto teased. "Is that how we say thanks?"

"U-um, what do you mean?" Sae stammered.

"The proper way sisters thank each other...is with a big kiss," Makoto said. "On the lips."

Sae went beet red. "O-oh, um, I must've forgotten..."

"Well, get to it!" Makoto ordered.
