Book of Lust

A NSFW time-management/rpg/visual novel in which you play as Jake Hart; a somewhat average young man.  One day, he's given a mysterious spellbook and accidentallyreleases a succubus.  Embark on a journey of complete and utter degeneracy as you mind control, swap bodies, birth demons, and order your personal succubus to possess those around you.


Fetishes so far:

-Mind Control
-Body swap
-Hentai Dialogue


There will be Male/Male and Female/Female pairings, but I wanted to try keep them optional.  You won't see any of these unless you actively start looking for them.


Olivia's Room

Jake in (Possessed) Olivia's room.


Possessing Cassandra

Your demon possessing Cassandra.


Swapping Bodies


Swapping Bodies with Olivia.

A while ago this game looked very silly, but now it's getting really better and better. I wish there was more m/m content. The only other male character appeared to be non-possesable for the succubus (I wished I turned him into an incubus)). Also, this same game could be done in non-furry more realistic mode. Also, sex with relatives... well.. not everyone's cup of tea (fortunatelly)).

As a transformation game i have to give it a "meh" not much actual transformation happening, possession yes, transformation not really. but the possession cause a form shift into a sluttier version so it's not completly no TF just very limited.

Now i actually like the game the dialogue is deliciously cheesy, and the art is nice, the story is showing promise and the spells are fun to try out, so all it really needs is more content that seems to be quite steadily flow in to make it really good.

interface could use some work, walking around at the moment require quite a few too many clicks i think, having a map view and pick where you wanna go rather then how it is now "Clicking up the travel mode, click arrows to walk, click buss station, click location, click movement arrows untill you get where you want, then click down the travel mode", the huge amount of clicking for travel kind of becomes a pain if you wanna spend time with different people each day and since people move around you have too so it's a lot of clicking travel mode and arrows and get a bit tedious.

Overall i recommend for people to try it.

This game is shaping up to be very interesting, and what's available so far is qute fun to mess around with. The progression system is quite interesting, and more or less rewards you for using the more unusual options at your disposal by giving more exp for them, though you can certainly just go through the same scene over and over again to unlock everything if you want to. The spells are all fun and interesting to use, as they should be, since they're the main focus of the gameplay. The side stories you can fulfill are interesting, since they act as a sort of puzzle that you have to figure out which characters and powers to use in what way in order to complete them, and they reward you with more scenes that you couldn't otherwise access. 

However, like all things, there is a caveat here: as this game is in development, and as of the time I'm writing this, you have very few options available to you for any given character. Almost none of the spells work on every character yet, and the more complex the spell, the fewer characters it works on so far. The most interesting spells, which are the ones that most heavily affect gameplay, those being the possession spells and the mind control spells, work on very few characters, and the characters they do work on seem to have very few options and scenes when under the effects of those spells. You can only possess three characters, two of which have almost no scenes to speak of while playing as them. You can only make your succubus control a grand total of two characters so far, including the one she starts the game as. The only characters you can effectively mind control so far seem to be your immediate family, with the spell being able to be cast on other characters but without the option of actually commanding them to do anything. While I can understand why the writer/developer has chosen to add new characters before fleshing out the available spells, it continues to frustrate me somewhat that almost every update goes by without really adding functionality to any spells except for the most basic ones.

I played this before not updated versions but I am certain somewhere on hard drive I have say I completed didn't sit well with me.


Some part me wishes you could play girl character and had dad and brother but that just me thinking it...mix and match you think.


Guy characters are nice just they get kind dull when you limit them and you set restrictions. they can't do this or that unless you have money like what heck why not. You have to build up desire bar what heck. Demons are made of horny desire...its bizzare you have build it up bar every time. He could just go in room masturbate come back nope...he has get inspiration I guess. Level up his powers before he releases the demon and continue her journey he could send her back or seal her?


My option would been for his sister...send her to hell token of love to demon. His sister's room could get renovated for nursery where is love I have no love for that sister she beat him right so I see nothing in her future besides sending her where she belongs.


If there was girl character what would she done differently if she had sister who never helped her out against bullies? I don't know? Or if that was brother instead who shined up motorcyle everyday and had fetish for his sister. Father who drank beer/went to sleep and worked all day and they had mom who was stripper. Well nothing everything... its just idea you never see people putting that in game.

So in this game literally you given task to do what whatever person failed before and had his soul literally drained...by succubus who enjoyed thought of it or maybe he passed who knows to level up all the skills to point until final one...become demon master?


If I had that book I put back where I found it relabel book of boring art it stay hidden baby...but that just me.
