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.

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.

Played 2 games tonight, one thats been in development for 2 years with a bunch of people throwing money at it, and then this one. It baffles me how this free game has 100x more erotic content and gameplay than that piece of trash and yet people still throw money at it hoping the devs will do something with that overly ambitious garbage. They didn't even make a custom engine so can't use that as an excuse.

I'm looking forward to seeing where this goes and this is a game I would actually put money on. Nice art style if a bit rough but with animations as well, something not all that common in the adult genre of gaming.  Also nice to have the art/animation drafts as placeholder, looking forward to the finished product there. No criticism as of the content I've played so far, just hoping the game gets finished and doesn't end up abandoned like a good many other games do on this site. Though at this point for what i played even if it did get abandoned I feel like my time was not wasted unlike the other game.

I personally like this game but one sugggestion I have is allowing jake to become a female that could really spin things on its head and maybe allowing us to genderbend the other characters?

So Far the game has quite good structure, decent to good art, and reasonable amount of content.

The begining is fairly grindy in getting xp by having sex talking to people to get them primmed for sex and just resting to recover stamina and mp.

But right now it does have debug cheats that can allow you to skip most or all or the grinding. 

There are a number of scenes that are currently rough sketches of varying degrees of completeness but I honestly see this as a better alternative to the no content message.

I have to wonder if in the future there will be any lasting influence on the npc's that have interactions to the players influence and spells along with any changes that are happening around them. I know some of it is perception blocked but it could be have flavor text of they can't tell whats different but that something is.

I also wonder what the future content will hold if the spells and their effects will be extended/expanded or if it will focus on more scenes and npc's to interact with. Right now it could use more npc's. If nothing else Julia and her mother would be obvious prosepects.

One idea would be to add a money system where the player can spend stamina to earn money and then spend money on items or improved actions with npc's. This would give the player something more to do than just grinding towards exp and sex.


Overall I would recomend this game as one to try and one to follow.


I am eager to see how this progresses.
