Jeff decided on transforming some human female into a Succubus. When ever Jeff watches monster girl type hentai during his free time, his favorite characters are usually a Succubus. He doesn't really know why he likes Succubus pacifically, maybe because they are the most mysterious Monster Girl out of them all? He was always curious on what life is like knowing someone that's close to you that is also a Succubus.
Jeff was getting a little worried that host(s) might kill him, their morality might disappear. He doesn't want that, so he decided to play it safe by turning off that extra edition of a monster girl mentality to the selected females host(s). He want's the selected host(s) to still behave like a human, and to still be themselves, whilst their species is a Succubus. Next, he decided to leave on the "Change your reality that it's always been this way!" parameter, he doesn't want the selected host(s) to freak out when they just turned this way. He want's the host(s) totally unaware of the changes. Lastly, he set the duration to 'infinite' he did this because to him he sees no point of a duration, if he can stop it at will on anytime.
"Wait a minute! What if people question, the selected host(s)?!" Jeff thought to himself nervously. He then decided to pull up the selected monster's description, wanting to know what it's exclusive powers are.
The description as it follows "A succubus is like a human, but at the same time have a demonic-like body and demonic powers. Succubus in a way are still human, they can still reproduce with human males exactly like any other female human, but if she (the selected host(s)) ever haves a female sibling they will become a Succubus. Now if they ever reproduce a male that won't be the case, they will just be a regular human. Succubus can use magic at will, they can hide their Succubus appearance from the public if they want to, do not expect to see a succubus right away after the transformation because they usually hide themselves at all times. Succubi usually prey on emotionally weak human males, by stealing their soul, and body through some sort of sexual activity. But, they can consume any human male without seducing them, that's basically the hard way for them to catch their prey. They consume human male's usually for enhancing their own features, get closer to someone, or to gain more power. The appearance, extra body anatomy, body anatomy rearrangement, and how they eat, completely depends on the person in which you target. If you don't like some of these features, you can always adjust the transformation or changes at your hearts content!~"
"Oh alright, I guess worrying about publicity won't be an issue, well that depends on the person I guess." Jeff again thought to himself in a relieved look on his face, and the fact that Succubi can reproduce with a human is kinda nice. Meaning if he selects his own girlfriend, he can still get married and have children. One of the other options can be selecting his own mother. Not that you are only selecting you own mother to be a Succubus, but both your younger and older sister will also be a Succubus. Jeff is satisfied with what he has set up, no need to change anymore parameters. He is done with that part...
Now, Jeff has to make a decision. There are so many people he knows on the top of his head to choose from. He thinks about it more, his mom is currently out at work. She works for a hospital as a nurse, actually she will be home at any minute by now. His older sister is at a her friends house hanging out, who knows when she will come back home. His younger sister is currently in the house relaxing down stairs, she is kinda lazy in some ways. Thinking about his girlfriend on the other hand, she is out interviewing for a company trying to get a job at an art studio, she said that she will call him back soon later after the interview. Thinking about his girlfriend's friends, you have no idea what they are doing currently. Who should he pick? What will he do?
