No sex with wife in bathroom yet. It's quite time consuming to make full sex animations(especially in the shower—the fact that the daughter scene was in the shower probably added days to the release, and that only featured one half-assed animation) and the wife doesn't seem to be near the top of most people's lists. Next update is Sara-focused so (spoiler alert)don't expect any sex there yet, so I may actually look into doing another wife sex animation, for the weekend.
That's an exclusive sneak peak, but also don't hold me to it because I may change my mind completely. I will definitely work on having her interactions with you in general be more friendly if you've managed to raise her affection/romance, though.
"What's the point of the boutique and the new shoes? Seems like a non sequitur."
The shoes give +20 romance with Kait, +15 with anne, +10 with the other girls except for Meg, who is unimpressed (note: you have to actually buy them for this to trigger, adding them to your inventory by console won't work). In the future the boutique will sell clothes to increase romance/affection and just look sexy on yo' girl.
