A super-erotic, lovey-dovey, sweet cohabitation sim rendered in full Live2D & full animation! From sweet touch and feel to detailed cross-sections and intense sex. Your sugar-baby childhood friend, Umi-nee, is waiting for you...
【Game Overview】
What is it like to live a lazy, sexual life with your freeloading childhood friend? This is a high-immersion cohabitation simulation game with your older-sister-figure, Umi-nee, powered by full Live2D and fluid animations (Hentai / Adult / Eros / R18).
Boost her affection through [Talk], [Touch & Feel], and [Sex / Ecchi] to enjoy her shifting reactions! Her responses change based on her mood and love meter. As you dive deeper into your sweet lovey-dovey days, the time will come to take responsibility with extreme creampies (cumshots)!
*Note: "Nee" (Sister) is used as an affectionate term for an older woman. You are NOT biologically related, so feel free to enjoy pure, unrestricted sex!
