High rates of intestinal parasitism are found in MSM [men who have sex with men] throughout the world.
Amoebiasis has become endemic in MSM in Japan and causes significant morbidity and mortality; complications such as colitis and liver abscesses occur more frequently in homosexual and bisexual men than in heterosexual men. Similar findings on amoebiasis are reported from Taiwan, with MSM at increased risk for invasive amoebiasis and intestinal colonisation with E. histolytica.

I followed this artist back when they actually did a lot of commissions an other art in the furry community. Then they went AWOL for a long time an then came back working on this game….I had been super excited to see them back but now it’s just evident they are milking people for money with this.

Anonymous Fapper

still boring with not much going on.

mrttao review part 3

You are a furry. you find a book bound demon. it turns you into effectively a demonic copy of yourself possessing yourself. So long as you remain in your original body, it makes no difference… but you can potentially hop bodies to other people and then cuck your unaware original.
The body hopping grinds development to a halt because every fucking NPC needs scene fucking every other NPC. As anyone who understands basic math knows the result of it is exponential.


If you had 1 MC and 10 NPCs. and added an 11th NPC. then that means 1 more pairing (MC + Char 11). But if instead any of the 10 can be the MC, then adding an 11th one changes the number of possible pairings from 2^10 to 2^11. And that is not getting into threesomes, or variants where you have more than one scene.

Anonymous Fapper

2^11 is 2048. I think you mean something else here. If there are 10 characters and any two can have a sex scene, then you’re looking at 10×9 = 90 pairings. Adding an 11th character means 11×10 = 110. So that’s an extra 20 scenes, not double the scenes.


Almost, but not quite. For all scenes featuring 2 people, you need to divide your number by 2. If there are 10 NPCs there are 45 unique two-person combinations. Adding another would give 55 unique combinations. The formula is [(n-1)/2]*n


If you only play as the original male MC. then you can fuck your mother, sister, next door neighbor GF, GF’s mother, sister’s boyfriend (you can make her break up with him), sister’s boyfriend’s roomate and sister. a minor goddess, and some rando women.
You can also have your succubus possess most of these girls (by default she possesses your mother).

The art is pretty decent. But there is not that much content if you are not into some very weird shit like cucking yourself.

Anonymous Fapper

How did you make the sister breake up with her bf?


IIRC I used the mind control to order her to not answer the door when he comes over anymore.

Anonymous Fapper

Ok so this guy dint like the game and now is talking shit, lest fix this
First YES is a furry game, the demon possess your MOTHER and later you gain the hability to possess someone else instead, when you do this the sex scenes change, you can also make you demon fuck someone else AND you can gain the hability to you yourself possess somne else, is like mind control or remote control, when you do that your bodys stays in auto pilot, thats why you can “cuck yourself” continuous………..

Anonymous Fapper

Part 2: “cuck yourself” is the stupidiest thing i have ever read, this tell me mrttao is a cuck irl and just cant stand any form of sharing or he is a cuck and this is his fetish, everything else is pretty accurate, and it is true THIS GAME WILL NEVER BE FINISH because all sex scenes are animated (or will be) and they change depending of if the characeter is possess and by who, the game also i suppoused to have story but with all the literal fucking going on it will never progress

Anonymous Fapper

Part 3: Still this game is really cool and even if it only reachess 30% completion is still woth suppoting

  1. fuck off subhuman
  2. its cucking yourself because you can body hop to another men, leaving a duplicate of yourself. then any of the girls you fuck are being stolen from the copy of yourself you left behind.
Anonymous Fapper

only a true retard would think that

Anonymous Fapper

only a subhuman cuck like you would lie and claim it isn’t cucking yourself.
why do cucks work so hard to deny their own fetish?

>ackshually, it is not NTR because XYZ
every fucking time. can’t they just admit they are cucks?

Anonymous Fapper

oh my god you like begin cuck so much that you come up with this shit so you can “cuck yourself” i get now


> the demon possess your MOTHER and later you gain the hability to possess someone else instead
facepalm. this is not a correction you idiot. It is BOTH
The succubus in the book possesses your mother. She can body hop to other people
you the MC can ALSO body hop to other people

When you body hop, your original body is still around… and is actually just who you were before you got the book.

Anonymous Fapper

Thanks Jesus, don’t let those cucks in denial fool us!!
