Succubus world?

Sauce on that pic?

Jesus Christ dude, it's my fetish as well, but holy fuck. You're unironically trying to magical realm Veeky Forums, here. Badly. With shitty, straight up vanilla wish-fulfillment. Are you actually 16?

If you're going to insert your fetishes, at least make it subtle and interesting. Maybe write up a warlock pact with a succubus, including the conflict and drawbacks of something like that. If you actually want to make it entertaining for other people, take all the sex (with your self insert) out of it and explore how succubi and pretty much every other demon are really fucked up with an eternal, agonizing desire to consume and torment souls. Or maybe she's trying to seduce him, but because of the pact he can see that she's really this hideous extraplanar shape-shifting horror. Mix it up a little, make things interesting, or just at least save the fap fiction for yourself.

Okay, I realize the image is too small for reverse search but, have you at least tried to go by that one keyword you're given in the post plus the very obvious tags the sauce should have?

I'm not a smart man...

Make dildos out of nuclear waste and dismiss the sucubi to permanently dispose of it.

>The heat death of the universe is just the end result of Hell's multi-billion year plan to steal shit from the universe so slowly that the Heavens don't notice until it's too late
>Entropy is a lie perpetuated by Satan to cover his tracks in case any humans caught on to what he was doing.
>The Succubi occupation of every man's bedroom is simply the next stage in the plan, upgrading from manually siphoning hydrogen molecules from outer space to (relatively) rapidly taking material from our universe, accelerating the end of the universe by another 10^92 years

Give the succubi nuclear enemas.

>The succubi are only willing to do it if it's sexual.
>Government scours the globe for the guy whose fetish it is for a girl to fuck herself with radioactive waste.
>Veeky Forums was a government seeding program all along.

Who'd have thunk?

>Veeky Forums and /d/ will save the world together by disposing of all nuclear waste

I can believe it

It's like the X-rated parody of Diane Duane's Young Wizards series that nobody asked for.
