Recently, a sister trying to cheer up her unemployed hikkikomori NEET brother. Every time she listens to his requests and encourages him, he becomes more energetic, but his pent-up desires explode, making him aroused... "Oh, big brother, you're getting excited down there!" A cute big-breasted sister and plenty of in-out incestuous sex "Eeh~! Are we going to have a baby? Big brother's sex was really great, so do it again?"
