Exhibitionism definitely, voyeuristic/sneaking: yesish, it's all done out in the open pretty much so not much sneaking but under the eyes of the significant others.
Very nice game, like a tamer version of the gloriously dirty Project Myriam, and with a much prettier MC. I did two runthroughs, one where MC Sluttyc*nt says yes to almost everything (she just declined the invitation of the butch girl with the bike) and absolutely everyone is turned on by her and everyone goes along with whatever she does. Then I renamed her Purity and she said no to everything, even her husband - and then she pretty much behaves like you expect a mother to behave (responsibly and totally not sexualizing her offspring). There's only one weird exception: the close encounter with Vera at the party still occurs, there's no option there, though you can say no to literally everything else. It's a bit strange as Purity shut down Vera at every opportunity and there was no sexual tension between them anymore, so it feels like that should have also had an 'off' switch (especially since the people witnessing the event would have been really shocked by it in this iteration of the tale).
Don't know where this is intended to go, exactly, as there is no real solid plot line in place yet, but interested in finding out.
