About this point, I mean if someone were to find out you play this game. Then they will also see the images of a little Dylan and Sam groping Sophia, a 17yr old ( under 18) daughter and a 16 yr old Son ( again under 18, I mention it because the people you refer to won't care about age of consent and stuff, if your character is under 18, it is illegal in their eyes, no justification is enough for them ) trying to fuck their own mother, neighbors kids trying to get into her pants, a teacher getting blackmailed by a teenager, sexual harassment, naked old men being bathed. Son masturbating to his mom etc etc..... While remembering the son is just 6-8 months older than the oldest boy in the other storyline. You say all this is totally justifiable to others but just this one route isn't. If someone finds out at your respective works that you play such a game and have images like this on your laptop, you're fucked anyways.
So this whole point about the images getting seen and it being a issue is no valid argument here. Also why do you want to extract the images and then keep this set of images on your PC. Delete them. And I don't expect someone to have access to your laptop for so long at work that they go through entire awam to reach day 19 and see this event ( also to see this event they will have to refuse the first job, which anyway playing for the first time won't refuse. So a first playthrough will never even show them the storyline. )
Also I would like to say that there are games here with tons of other fetishes which are actually bizarre but people still play them. As for ILLEGAL, so is incest. but then again I don't want to debate on the legality once again. Most of the things that happen in this game can definitely get one to prison in real life. But that's the point, this isn't real life but merely a fictional game, harming no one where one can engage in a fetish of their desire without being judged.
