Mary rips the sheet off and discovers Ririka’s state of undress

Mary looked at Ririka and rolled her eyes. She took hold of the sheet, which Ririka desperately clung to. “Come on, Ririka. You were the one who wanted to work together to win the presidential election! You can’t back out now! Not when we’re so close!”

Ririka held on for dear life, but lost her grip as Mary yanked the sheet away from her body, leaving Ririka sitting on her bed completely naked and completely exposed to Mary as the sheet was tossed away. Ririka immediately, desperately covered her body, blushing as Mary stood there in surprise.

“Ririka? Why are you naked?” Mary asked.

Ririka blushed. “I... sometimes sleep naked,” she confessed, looking down, away from Mary.

“Oh,” Mary said. “Why didn’t you just tell me that?”

Ririka looked up in surprise as Mary grinned. “T-tell you? Why would I tell you I sleep naked?!” Ririka stammered. “It’s embarrassing?”

“If it’s embarrassing why do it?” Mary asked.

“It’s only embarrassing if I get caught,” Ririka said, biting her bottom lip nervously. “It’s... honestly part of a gamble. Kirari always did the same, except she would take things further, sometimes even tying herself to the bed, trapping herself until someone let her out or until she satisfied herself. It’s... a Momobami tradition.”

“Momobami tradition, ay?” Mary said. “Oh that gives me an idea, if you’re interested. I propose a wager.”

“W-what’s your wager?” Ririka asked.

“I tie you up, spread eagle, helpless of covering yourself. If no one enters and catches you in the next 60 minutes, you win, but if you’re caught, you lose. The price is a forfeit. The winner gets to determine what the loser does next,” Mary said. “Do you agree?”

“Fine, I accept your terms,” Ririka said.

“Great,” Mary said, and immediately took Ririka’s arms and pulled them away from her body.

“Wait!” Ririka cried.

“It’s too late, you agreed to this,” Mary said, cuffing Ririka’s right wrist to the right side of the bed, and then cuffing her left wrist to the left side of the bed.

Then she did the same with Ririka’s ankles until Ririka was completely trapped lying spread eagle on the bed, unable to preserve an ounce of modesty as Mary looked at her.
