Well, then, Nie Huaisang is going to very carefully explore the merits of knees and spines and upper arms, not to mention necks and ears and thighs and fingers, and very conspicuously fail to explore the merits of dicks, balls, or assholes.

It's so... nice? Equal parts relaxing and arousing. He's being touched so gently and thoroughly and it's... pleasant.

--if this plan is to get him frustrated, this may be a flaw with it.

If Wen Ning likes having fingers gently traced up his thighs and followed with Nie Huaisang's mouth then who is Nie Huaisang to question this.

He certainly isn't going to complain about it.

...maybe squirm about it a bit, though.

Squirming means it is time for hipbone licking.

It is Known.

He better take notes on it then.

Nie Huaisang pauses and then lightly breathes on Wen Ning's dick, and then goes back to placing lines of kisses along his stomach.

...he may be seeing the merits of teasing now, other than it just feeling nice in the moment. He may be sensitive and innocent, but being breathed on shouldn't feel like that much.

They kiss and touch Wen Ning and then every few minutes or so they interrupt it to kiss his dick, or breathe on it, or do a single long lick from the bottom to the top, and then it's back to sucking on his fingers or nibbling the upper part of his ear.

--yep he's definitely getting the appeal now.

(He's currently on a knife edge between wanting to be touched properly, and wanting this to never stop, and it's a weird sensation.)

What if Nie Huaisang kisses allllllll around his dick and doesn't kiss his dick at all even a little bit. 

They might get an embarassing whimper that leads Wen Ning to clapping a hand over his mouth.

...not that his hand is on his mouth for any particular reason right now, you understand.

No, of course it is not. 

"That's what tying people up is for, or one of the things," Nie Huaisang says, conspicuously not touching Wen Ning's dick. "So there's nothing you can do about it while I'm teasing you."

"I'd just have to-- take it."

"Mhm." They run a finger lightly up Wen Ning's dick. "Another thing that's fun to do is to get someone all worked up and then leave them all desperate and unsatisfied. What do you think of that?"

"There'd be nothing I could do about it. Hypothetically." Which is as close to saying what he actually thinks about it as he can get.

"I wonder if I should be nice today or mean. I was very nice to you earlier..."

A spell family has been created by a special action! Ferocious teasing by Nie Huaisang has unlocked the spell family Edge Riding. 

Manual // Spell // Edge Riding

This spell allows you to stay near orgasm without going over. Go as near orgasm as you are ordered. Stay there. Drop down. Back up. Right to the ultimate edge. Down slowly, up slowly. Good Boy. Now repeat that until you're told to stop. In its ultimate form, this skill becomes the final mastery and control of your own distance from orgasm. 

Edge Self: When invoked, no matter what happens, you will not be able to come for the next minute. (This spell may be cast by thinking the relevant words in the Speech. Try not to think them by accident.)

"It would only be fair to let you be mean now."

"Maybe I'm just a kind and generous person." Another finger along Wen Ning's dick. 

"You are a ridiculously generous person," he says, with great appreciation. "I only had to ask--"

"I don't suppose you've heard of ruined orgasms." They lightly trace a zig-zag pattern on Wen Ning's dick. 

"I haven't come across those yet." It is surprisingly difficult to concentrate.

"If I get you up to the point of no return and then take my hand away"-- they do so-- "you'll still come. Just in a way that's frustrating and unsatisfying and leaves you craving more. You can get male multiple orgasms that way."

That seems... biologically implausible, but what does he know? "That sounds... interesting."
