Tensho solitary, old-fashioned brother and sister ... but after the engagement of my older brother, my younger sister makes me run away with her feelings for my older brother! "Oechan, let's go inside... Let's make a baby," said the sister, who was jealous of her brother's fiancée, naked on top of her sleeping brother and desperately blown up Chikupo. My brother's reason easily collapses in the form of a adorable and obedient sister serving hard...! look at everything.
