Yes, with very few terms!

"...okay, yeah, I think I can go with the flow on this one," Ren nodded.

"That's your general attitude towards life, isn't it?" Jaune snorted, getting a faintly amused look from Ren in response. "That's why you let Nora drag you along on every harebrained idea that pops into her mind."

"...true, but it's a perfectly valid way to go through life. Less stressful when you just roll with things," Ren replied.

Blake then asked, "Alright, so what sort of terms do you have for being included in our little group?"

Ren thought about it for a moment. "...well, if you want to include Nora in it later, do try to keep her exhausted as much as you can," he remarked with a snort. "She'll probably want to cling to me a lot. Which is fine, I just want smaller doses of her," Ren noted.

"Sounds good to me!" Ruby nodded. "What else?"

"... honestly, I cannot think of much else that I wouldn't do... Other than no piss or scat play, no blood, or vomit, shit like that..." Ren grimaced. "Not that I expect you to be into that, just covering a few bases."

"Got it."

"And... Perhaps I should also ask for a safe word in case we do encounter something else I don't want to do?" Ren suggested. "Might keep things from getting crazy."
