Funny succubus story

Forgot the premise. But essentially succubus gets summoned/hunts the guy while wandering the night. Makes a pact. Start having sex. Draining the guy (like literally his life force). Wandering angel (or rather hunting for that particular succubus) shows up and interrupts them. Tells him fight the urge yada yada... guy doesn't care. Is addicted to succubae pussy atm. Advises him to do something while fucking the succubus. Guy does. Voids contract. Succubus is defeated.
Succubus is now human. Is pregnant with the guy's child. Sends the guy off to work with a kiss while vowing revenge.

bump.
