That was great, too bad I couldn't enjoy it in fullscreen because I love that artstyle.
I was starting to lose it when I had no clue how to dress her up, but in the end it was a neat approach.
I also wasn't a big fan of the incest part, but everything else was great, I especially loved the part where you start mashing for pleasure and then for each smash a neat warm pink color appears. If this game would be any longer - personally - I would only change:
1 - smoother animation when mashing
2 - music + smashing sounds to some "harder" sound effects with more bass or something
In the end, it's nicely done!
I'll make sure to check other games as well.
