"Unless you object." Kiss!

"Sounds like fun."

Sounds like permission for even more pushy kisses!

Maybe they should take this to the bed?

Sounds good! 

She pushes Incandesce back and onto the bed, straddling her before she can get herself situated, grabbing her hair to pull her in for another kiss. "Mmm," she murmurs. "I seem to recall something about only letting people burn themselves in private?"

"You're wearing too many clothes. Don't wanna set off the smoke alarm~"

Excess clothes can be fixed! Nice and slowly, of course, giving her audience a good chance to appreciate every inch of skin being revealed.

Audience: is very appreciative.

Does she stay still and watch like a good girl? 

Not wiggling is hard!

Ruby might need to pin her down better, so she can get undressed in peace...

Quite possibly.

Luckily her thighs are up to the job. (This involves shifting her position forward a little bit.)

A new and exciting vantage point!

Something for her to enjoy while Ruby finishes undressing.

Incandesce does very much enjoy it.

Excellent! 

And, once she's done: "Any other safety measures you want, cutie?"

"That seems good enough to get started."

Excellent! 

Ruby has ideas on where to start...

Well then. Started they shall get.

(Ruby may notice that Incandesce's entire body heats up when she does her pyrokinesis thing, ramping more and more over time.)

Very convenient then that Ruby is currently straddling her - enough heat gets her very wiggly and pressing down on Incandesce. (Incandesce might notice that not only is she not bothered psychologically by the heat - definitely a masochist - but she isn't having a lot of the subtle indicators of burns or overheating being a medical issue that Incandesce has been repeatedly warned to watch out for. She gets flushed and lightly sweaty and no worse, no matter where or how much heat Incandesce applies.)

She's keeping things at a safe level for playing, so that's not too surprising. Convenient, though. Means they can keep going longer.

And Ruby has a lot of stamina - and rewards Incandesce for good behavior, of course.
