Again if you're paying attention the setup is for them to have an open relationship.Hardly has anything to do with her needing to be pure but rather having a consistent character. Also, it was previously stated that Vi and Eric would maintain their relationship and that it wouldn't just be her becoming a wanton slut leaving Eric behind. As far as having bad writing because it's porn, that excuse is nonsensical. As well as acting as if people can't critique poor writing in general or that certain writing shouldn't be adjusted. There's a reason every professional writer has to work with an editor.
You can keep passively aggressively saying I am playing wrong but again, I would suggest you replay her scene in the alley with Eric. Once again, how is she acting so nervously about giving a handjob to Eric's best friend that her and Eric have mutually been teasing leading up to this. To then having no problem deepthroating a random guy with Eric having no involvement? That's the problem and completely inconsistent both with the build up of the previous update, the portrayal of the character, and the supposed vibe of their relationship as it has been presented until now. I get certain people just want as many gonzo sex scenes as possible in every game, which is fine, but there's also plenty of other mediums that provide that. In the case of visual novels/erotica like this, the difference maker is the writing and story.
Eric is often times fantasizing about Vi with other men. He's clearing dtf other women, without Vi,s permission and Vi is just assuming she has Erik's permission to go forward.
My complaint isn't that you're playing the game wrong. My complaint is that you're attaching erroneous feelings towards characters.
It is in fact ridiculous to hold porn game writers to the same standards as literature writers. Their entire premise is outside the boundaries of reality and deals strictly in the realm of fantasy.
