Your stepdaughter is a succubus!

[Brandnewbuddy]

Essentially our protagonist gets married to someone who has a daughter. They live happily as a family but when their stepdaughter becomes 18 years old, their partner reveals that their daughter is a succubus…and she needs to start feeding.

Multiple ways it could go, of course. Step-parent could be stepdad or stepmom. For this story let’s just say the succubus can enjoy sex with men or women but can only feed off of men and needs to ingest some sperm. A single coupling doesn’t need to be fatal but it should at least leave her partner exhausted.

Of course, the big plot is what does the step-parent do once they learn this knowledge?

For example: stepdad has always been faithful to his wife and loves his stepdaughter like she was his own blood, but now his wife is asking for him to either help feed their daughter or find men to use to feed her, both concepts which are at least initially unappealing to him. Stepdaughter meanwhile reveals that while she loves him, she doesn’t have the same biological repulsion to the idea and is actually pretty eager for him to be her first lover/meal. How long cina stepdad hold out.

Alternatively: stepdad has never had any real leverage over his stepdaughter but with her nature revealed, he suddenly has some real leverage. He’ll always make sure she gets a meal but there’s a big difference between jerking himself off into a bowl and having her lick it up vs coupling with her. What’s more, stepdaughter soon finds out trying to hook up with other guys doesn’t give her as much of a kick (could be her mother practically scouted stepdad and realized he’d be a perfect fit for her daughter so she could keep her bahavior under control once she came of age).

Stepmom: similar concept though mom doesn’t have to fear being preyed on for sustenance…though that doesn’t mean she can’t get wrapped up into it.

One possibility could be that succubus plans to feed off of her own father (mother could be succubus who left her with him). Stepmom refuses but will allow stepdaughter to eat her out, with stepdaughter slowly enslaving her or stepmom breaking down and allowing her to join them.

Or, stepmom refuses to let stepdaughter get around so she starts fucking lots of guys and then coming home to be cleaned by her stepdaughter.

This e are just some ideas, what else can be done with the premise?

I always thought the whole idea of a succubus is that they feed on you to your detriment! Maybe not necessarily kill you the first time, but definitely not something you would want to make a habit of. If you are redefining that, fine, but otherwise, we have to deal with it.

How about the step dad decides to become a vigilante. He prowls the streets at night, step-daughter in tow, looking for evildoers. When he finds one in the act of committing a crime, he sics daughter-dearest on them. They willingly submit, thinking it is just some NSA sex, but then it turns out they are sucked within an inch of their lives.

There’s multiple interpretations. There’s even ones that state Succubii can be summoned safely if you are on good terms and are respectful towards Lillith, with incubii not being the male equivalent of Sucubii (since originally succubii would just flip between male and female bodies to seduce men for their seed and then impregnate women…once again, no loss of life they just ruined people’s lives) but rather the violent and dangerous side, usually summoned if you ticked Lillith off or performed a blood ritual to try and summon a succubus.

There’s also ones where it’s safe as long as you make a deal how much life they take, or keep them inside a circle of protection being careful to not crossover.
It’s a pretty open concept.

As for a vigilante idea, I could see that, though a darker take: stepdad takes stepdaughter around online, pretending to pimp her out to the worst of the worst. The buyers are happy to take a young woman and love the idea of a stepdad trafficking his daughter…only to lose their lives afterwards.

I like the idea.. I got a SRP going where my guy is a childhood friend of the girl next door who turns out to be a succubus. With my guy having had a crush on her for like 10 years and got accustomed to living in the friend zone. What made it bearable is she wasn't seeing anyone as that part of her hasn't turned on....

The plan is for her to use some magic to cast a spell to bind him to her for his safety... For a life long job of feeding her and helping her get others maybe to feed off of.. The spell also allows her to feed off the sexual drive of him being with others so as he is having sex with someone other the his succubus, she gets to feed from him threw him...

I can see her setting him up to be used as a sex toy for her girl friends. Maybe a glory hole bench for random females to sit on and he has to eat there pussy's out.. (may have to suggest that in my srp to them opening up a sex toy shop for that) for random females to use his mouth, just enjoying the oral... Till they are done and leave him to wait..

Succubi are demons, immortal unless destroyed supernaturally. What starts their existence, and when? Are they ever underage in contemporary times? If one even looks underage, she can't be a sexual player in a LIT story.

Possible setup: Our ancient succubus (who looks over 18) takes control of a middle-aged fellow and 'persuades' him to adopt her. Now the neighbor lad can fall for her and be LIT-legal. Whew.
