This is not something that came up in Great Tang that often, but Jing Yi has enough baseline knowledge to make reasonable guesses

ooooooooooooooh those are very reasonable guesses

Points to him for being able to improvise!

Rose is sure with vocal feedback he can improve his guesses.

Oh, feedback is good. He can sort of know what he is doing.

It doesn't take long for them either. Then they flop on his shoulder.

"Does Great Tang have cuddles after sex?"

Flopping is good. "We certainly can."

"Gilead didn't so much, men supposedly hated cuddling after sex."

"...What?"

"Biologically they just want to roll over and go to sleep. Apparently."

He nuzzles into their shoulder. "I have never in my life enjoyed a cuddle. I am completely physically incapable of it."

"Very self-sacrificial of you."

"I am the most generous person in the world," he mumbles into their shoulder.

"You know, I had my first orgasm seventeen months ago."

"...in Cascadia, I presume?"

"Yep. I wasn't sure how lesbian sex worked so I decided to check out a book on the subject and it was very persuasive about masturbation."

"I imagine it was."

Now they should snuggle and go to sleep.

This is an excellent plan, Rose is very warm and cuddleable.

Jing Yi wakes up to the smell of pancakes. 

Is Rose still in bed?

Evil people think mornings are a nonexistent time.

Aww, that's cute. But it does hinder his plans to check with them whether he should dive out a window to escape. (Probably not?)

...he can cuddle up to Rose for ten more minutes before facing the world and working out how speedy his exit should be

Rose doesn't intend to wake up.

Alas, he is going to have to be strong and peel himself out of the comfy warm bed and put clothes back on.

He walks out into the kitchen. "Silly ettiquette question: on a scale of one to ten, how much am I meant to be gone already?"
