As far as I understand, there is no "vanilla" route. Girls will be a public place anyway. There are vanilla sex scenes, but for the sake of this, spending a lot of time watching scenes where a girl is fucked by a bunch of men is not the most useful thing to do (IMHO).Be warned. The artist makes whore/slut hentai.
Dont expect some wholesome vanilla content. No doubt that the love interests will be used like toilets by other male characters.
If you do not like ntr,cheating,sharing,swining,cuckold,gangbangs etc .... I think you should skip this or wait till someone plays it and says if there is a "vanilla" route or something.
