If I see an idiotic, silly, or just plain boring story, such a game is deleted 30-40 minutes after starting a playthrough. Sex in games is in second or third place for me, the main thing is the game component.
Only on the replays, I started playing adult games because I got tired of mangas, as you would have 200 chapters of nothing and at the end on the last 2 pages the character would "get together", so when I discovered adult games which initially were only Japanese VNs, I loved (and still do) to read all that story, the characters knowing each other, interacting, going out, etc. before anything happened (I love romance and the build up), but then I started to know about other types of games with less build up that would go straight to the porn part, but despite that my way of playing ended up never changing, so now regardless when I want more story I look either for a Japanese VN or adult game where the focus is not just porn and in the first 4-5 minutes girls are already in love with the MC cock, not him, because if you pay attention most of the time it's his magical cock that does the job not him.
I'll play the game to the end if it's good.
I'll quit immediately if I don't like it.
I played to see the sex scenes, but I especially like it if the story is good too.
