Start slow

"It just feels a little weird to be doing this with you of all people." You replied. "But I'll get over it." You started looping the rope around her wrists and tied it off. "How does that feel?"

Sayori frowned at you. "You'll get over it? So you'd rather be doing this with someone else?"

"No, dummy." You shook your head and poked her forehead. "It's just that with how we basically grew up together, its hard to think of you in... you know, a sexy way. It's not that I don't want to, it'll just take a little time. If I didn't want to, I wouldn't be doing this."

"Oh." Sayori smiled. "That makes sense when you put it like that."

You tapped the rope around her wrists. "Now, you didn't answer. How does that feel?"

She wiggled her hands and tried to slip them out, then gave you a thumbs up. "I can't escape!"

"And it's not too tight? Or pinching anywhere?"

"Just a little." Sayori answered. "But that's fine, I don't want it to be loose."

"That's not fine." You tried to start untying the rope, but Sayori pulled her hands away.

She giggled as she stood up and started running away. "You'll have to catch me first!"

"Wha- Sayori!" You got up and started chasing after her. "That's not okay! I don't want you losing a finger or a hand because there wasn't proper blood flow!" You weren't actually sure what the exact consequences would be, but you figured it was something like that.

Sayori didn't stop, instead running past where Yuri was across Natsuki's lap with her skirt flipped up. You momentarily paused at the sight, but then shook it off and focused on your childhood friend.
