Voted for everything.
In my opinion girl should turn to "complete whore mode" when parasite infects her.
Egg laying must be in that kind of game.
Zombie should be more disgusting(at least you could make an option).
If it's a zombie game... Well, I'm not fan of this thing, but guro is also should be in the game(can't fucking believe I'm saying this, jesus, I'm getting more broken in my fucking head).
One more thing comes to my head: have you ever seen a normal girl being raped in her ass all the way through by tentacle and kissing(with tentacle coming out of mouth) zombie girl and then tentacle come out of zombie girl's ass and rapes both pussies? Taking maggots out of ass or by cunilingus/anilingus is too damn hot too.
Huge thing disappoints me in Parasite City - when you got raped by huge fly and give birth to it, fly comes out already adult. Why not include maggots/eggs, that crawl outside and inside if you get caught or taken down. No belly bulge from penetrations/insertions(or stomach deformation if you want), no x-ray, can't play as infected, walking around as pregnant looking girl is hot as hell, especially if you can see something crawl inside of her(these weird movings/moves on the belly skin).
You can call whatever you want, I haven't paid a penny for any game I've ever played with H-content. I love to complain, I love to share my opinion as everyone else around.
So here is few of my thoughts, I will gladly listen to people who want to tell me "go fuck yourself" or "draw it yourself and make your own game", agree with me and add some more delicious and pervert things, etc.
P.S. Internet is not perverted enough! NEED MORE.
