The "groping" scene when she is dancing in front of you was meant to be something like this, but yeah it's a bit lackluster right now, I might revisit it in a future update and make it a little sexier / more engaging.
As for the storyline, ending variant 1 should be completed some time this summer, hard to say for the other endings, as I haven't written the script completely yet (ending 1 is pretty much written, just needs a LOT of new art and voice acting).
