The main creator is getting close to being able to quit his current job and work full-time on SK (like 70% of the way already in terms of needed pledges). Once that happens, you can expect updates to be a lot faster.
But as for the story, the MC is still early in finding his way in the world, so it may take a bit longer before he can tie the knot. He still has to meet a lot of the upcoming cast first!!! But other kinds of spicy H-content will be coming in 0.04 very soon.
Kinda crazy how successful this game already is. Don't get me wrong, it's high quality but it's rare to see after just two updates and as a newcomer in the scene. There are so many games in this style (AVN's) already after all. But hey, more power to the game and it's creator. Would be cool if it all works out and this will become a full-time job. :)
