Complicated immortal stuff happened, and now the heavens has decreed that MC must be punished. The MLs try to keep MC's punishment from being too bad by defiling him themselves.

MC jumps directly into a futuristic universe where he's tasked by the heavens to collect the souls of the MLs. Enter the modern remakes of some of your favorite scenes. MC is now a prostitute who serves the MLs with the help of an advanced mobile app.

Prolapse: Yes, of both holes. If this is a hard no for you, then drop this book now because the author can't go one scene without describing bulging meat it at least twice.

Enemas/pumping and plugging: Yes, of both holes. Common descriptions include a belly "swollen like 3/5/7/10 months pregnant." Long descriptions of the release of whatever fluid or thing is stuck in MC.

Humiliation: Yes. Mostly in the form of public exposure/play, naughty language. Slightly related, MC acts as a prostitute every once in a while.

Dominance/submission: Occasionally, and mostly limited to pet play (think tail/ears). Lots of bondage (chains both thick and thin, ropes, silk, use your imagination).

Whipping/spanking: Mentioned in passing; there's more focus on the result than the process itself. Mostly on genital area. No blood is broken, ever, but later MC gets a taste for electric whips.

Edging/forced orgasms: MC's suffering is more in the direction of constant orgasms. As in he can't go two steps without one at some points.

Water works/urethra play: Yes, both holes. MC is incontinent. All the time. If constantly gushing fluids isn't your thing, drop this now. MC is also used as a toilet (urine).

Plugging: Yes, of pretty much all the holes. See MC's incontinence. Also including objects here (sticks, coins, lotus flowers, pinecones, dildos, vibrators, stalactites)... If you see something being described in detail, it's probably going to end up in MC soon.

Lactation/nipple play: Yes. Runs the gamut from opening/stretching to milking and even failure to milk (ow). MC develops enlarged nipples, rarely breasts.

Oral/fellatio: Yes, from both the MC and MLs.

Body modification: Limited to piercings, and even then only in two places (nipple and down there), not necessarily at the same time. No cutting, no burning, no needles (the sharp kind, but the dull ones are used for stretching). Blood appears very, very rarely (as in, someone cuts a finger. MC is so moist it's hard to hurt him like that).

Long Chi Le (Dragon lord) : Disciple of MC who was raised by him single-handedly. The youngest and shortest of the bunch. Like most snakes, he has two "horns." Very instinct-driven. Possessive of MC. He's pretty much the only one who's cried (the MC only gets "wet" around the eyes).

Chikui (Demon lord) : Redhead with "canine teeth". He has a thing for MC marrying him (wedding dress play) and bearing his children (no actual children are created, to his distress). Was captured by MC as a demon and has been confined in hell for the last 300 years.

Yuan Jixue (Ghost King) : The most creative, the technical dom of the bunch. Cool-headed. His scenes are the most complicated to MTL (as in, figuring out exactly what's going on). He propositioned MC in a past life, and was rejected.

Bai Xiao: Master (to his beloved disciple). The most open-minded, the caretaker dom of the bunch. He apparently took on MC's heavenly task/punishment in the past, which is now coming around to bite them. He's into seeing MC drop his icy countenance and acting sweet and lovable.

There are some light 3P/5P scenes; none of the MLs touch each other.

First things first, he likes all this. A lot.

He's a strong character; even when his physical strength is gone (cultivation sealed), his mental fortitude is iron-clad. If he decides to do something, he does it. He's not wishy-washy. He doesn't have any regrets. He is proud, but he isn't traumatized (he accepts his pleasure and doesn't feel ashamed of it — unless it's in a kinky way). If he's knocked down, he just gets back up again and he's smart about how he fights back. MC starts off as a righteous sword cultivator, and he actually breaks out some slick moves on the MLs and others (as in, he kills them in one stroke).

Normally he's a man of few words, but he isn't shy about expressing his likes and dislikes to the MLs. He's more of a masochist than a submissive. Not the typical queen shou, but it's clear the MLs would eat out of his hands if that got him off (which, it wouldn't, but they still eat him out *wink wink* anyway).

A wedding scene in which all 4 MLs play a part. One of the MLs gives the MC a diamond ring. The author's mini theater reveals that MC likes the ring (and that ML).
