And you think what, that a good and decent person would realistically jump immediately into to sex with their longtime-husband's younger brother in just a few weeks??? Jennifer is portrayed right from the beginning as a kind, shy, and genuinely nice person; she was never shown or implied to be a selfish whore who wants to embarass her husband to make herself feel better. There are
plenty of games out there (the vast majority, actually) where every female character immediately - and ridiculously - wants to have sex wtih the MC, so maybe one of those games would be more to your liking.
This game is telling a far more realistic story, and is therefore WAY more erotic and interesting to players looking for more then mindless sex cartoons. Nobody is forcing you to play this one, so why post condescendingly about it?

Not every single AVN out there caters to
my specific tastes, but I don't feel the need to go around posting negative comments about the ones that don't. [
Unless they pretend to be one thing to lure in players but then change into something else mid-way through - that's a whole different story.] But this AVN is titled "My Brother's Wife" and did not show sex scenes with Jennifer in the previews right when it started, so any
expectations of anything more than a sexy story about a sister-in-law
come from players making incorrect assumptions, and TBH that is not the dev's problem and he is not required to change his story just because some players make false assumptions and then get angry when it turns out they were wrong.
So if you thought the latest scene with MC and Jennifer was anything less than super-charged sexiness, as I did, that's fine. But why act like there is something "wrong" with the pacing just because
you aren't into a slow-burn game that nobody asked you to play?? There probably should be a "Slow Burn" tag on games like these, but since there isn't you just have to play attention to how the game is unfurling at the start to get a pretty good idea of where it is going and how it is going to get there.
