Life in Wonderland

You're the only man on an island full of sexy milfs, young erotic girls, and familiar faces pulled from various anime and video games, and every single one of them is already in your harem. There's no hour of courtship to sit through here; the conquest is over before it starts, and everything that follows is sex. The stated goal is simple: get them pregnant, and understand that once they're waiting on the fruit of your love, they'll need your attention more than ever.

The loop is pampering rather than pursuing. You move between your girls, keep them satisfied, and watch the harem grow instead of chasing anyone into bed. It plays like a hentai novel built to stay focused on exactly that, with nothing else competing for the runtime.
