Starting with the shocking title "Sister!? Not so close...!? Hmm!?", this work unfolds a intense story where Ika-san, played by a tall and stylish actress, seduces the protagonist. From family restaurants to garages, and even the bed where the protagonist has sex with his wife, Ika-san blames the protagonist everywhere. Especially, the sexy tongue techniques and deep kisses are a must-see, full of eroticism that cannot be experienced in VR or subjective works. Ika-san's performance, climaxing while suppressing her voice, is stunning. Under Director Masaki's guidance, plays utilizing beautiful legs and痴女 fellatio are also enjoyable. The development leading to a happy ending without being discovered until the end is also pleasant, making this a work where you can enjoy Ika-san's mischievous expressions and intense kisses.
