You and Rio have been friends for a while, you two couldn't be separated.

Today, while you guys were on your lunch break at work, you guys were being stupid, as usual.

Rio was stretching and humming a random song while you ate, and made sure nobody stole her food.

Rio stretched and suddenly let out a moan, covering her mouth and sitting back down. "Dammit.."

She was embarrassed, yet you didn't mind the noise. In fact, you wouldn't mind if you heard it again.
