Porn games are better when the characters are fleshed out, have actual motivations, and their actions are at least somewhat sensible. The build up and atmosphere that comes with the development makes the payoff much more satisfying.
This game tries to do that and is mostly succeeding so far. Yes, that means the pacing is slower, and that it's an in-development game only makes that fact much more noticeable. But, it should be worth it.
If patience is not your forte or you insist upon instant gratification, simply wait until the game is at least a few more updates deep before touching it.
That is not to say there is no titillating content of any kind in each update, but rather, so far, it's usually of a more subtle, atmospheric and teasing variety instead of outright pornography. The latter is on the way but, with a few exceptions, it's not here yet (as of 0.04) and is still being built up to.
