Anehame: Ore no Hatsukoi ga Jisshi na Wake ga Nai 2

Akira let his momentum carry him away and had sex with his sister, Rio. When the afterglow of the sex was still fresh in his mind, Rio suggested they go to a love hotel. Akira and Rio arrive at the love hotel together in her sister's car, but Akira is confused by the fact that he has never been to this place before. Rio pulls Akira's hand with a laugh. They enter the room and immediately get into the bathtub. Rio is happy to see her sister and brother together, but Akira, who has had sex with Rio once before, sees her not as a noisy, caring older sister but as a sexual object.
