The dev doesn't rush the updates. It's about a year of waiting.
But the story? Man, all sex/lewd scenes happen the very first day of the story in about six hours or less. The MC is a 19 y.o. virgin (yes, he had sex with a girl when he was so drunk that he doesn't even remember the girl... he's virgin) that can seduce eight girls and mature women that he didn't know previously (except one) like a professional gigolo.
The guy, first fucks a MILF and doesn't even know her name, then in the pool seduces the brunette girl that didn't know a couple or three hours ago, and she falls for him, then goes to a strip club where he fucks a girl he barely knows in front of a woman that barely knows, gets drunk, returns to the house where he flirts with the sister of the MILF that he fucked that afternoon, seduces the redhead that barely knows, seduces Eve, that barely knows and lets her play with his cock, and then gets a blowjob from his childhood friend... If this isn't to rush into sex scenes... Only the last one makes any sense since, at least, his old friend had felt for him time ago. The other ones? MC has a magic cock and the mad seduction skills of a Casanova... being a 19 years old virgin.
The waiting between updates was so long that the dev was afraid that people could lose interest in this game if this update weren't "juicy" enough, so he packed a lot of lewd/sex scenes in it. It's OK, but it could have been way better done if the dev would know how actually write a script, not just packing a scene after another without transitions in the story.
About "maybe this VN isn't for you", is funny. I'm sure the devs love when fans of a game, to defend it, say to potential patrons "maybe this game isn't for you" after the first criticism.
