I don't remember myself exactly, since i wasn't really into the nsfw stuff of this game, since the plot is actually dope, but, you can fuck a lot, get a lot of blowjobs.
you can fuck a zombie like thingie with your tentacles, you will know what i mean when you get to it.
there ain't any crazy shit. though i think there is some foot shit where the hoe makes you cum with her feet. uhh, and... ye there is ntr, you can also get fucked when you become a female and take the choice to get fucked.
you can be a full blown woman or a futa. and have futa sex.
i think this is the gist of it. hope this helps.
