All the girls are very quick to bang the player, it's just part of this game's pacing :P
Although I don't know whether that's just NCrow's preference, or a response to the general porn game community of "why do games take so long to get to the sex", lol.
Personally, I'd like the sex to take a bit longer to get to, same as you. I'd also like better proofreading, but hey, English ain't the dev's first language, more than fair enough.
