Mary catches Ririka in a compromising position.

Ririka was laying naked in bed, asleep when Mary came barging in. “Ririka, wake up, we’re going to be gambling today,” Mary said.

Ririka stirred awake and blushed at the realization that Mary was looking right at her, the only thing between Mary and Ririka’s naked body was a sheet that Ririka hoped Mary couldn’t see through. “Mary?” Ririka said in surprise. “W-what are you doing in my room?”

“Please, I’ve been in here plenty of time, it’s not like it’s ever been a big deal before,” Mary said, rolling her eyes. “Come on, get up and join us in this gamble. It’s going to involve Yumeko and Kirari and I don’t want to be alone in this.”

Ririka didn’t know how to respond. Of course she wanted to join! But... she didn’t want Mary to know she had been sleeping naked. If Mary knew, she’d never hear the end of it, but if she didn’t get up, Mary would probably know something was up anyways. “Of course I want to join,” Ririka said. “But I need you to leave first!”

“Why do you need me to leave, Ririka?” Mary asked. “Shouldn’t we just go together?”

“Mary, please. Just leave the room,” Ririka pleaded, wincing as she realized how unconvincing and more suspicious that sounded.

Mary stood there for a moment and looked Ririka up and down, contemplating what to do.
