I moved in to live with my brother and sister-in-law Nao Jinguji to make it convenient for me to go to school and work. Living with both of them, I often have to witness the passionate scenes of brothers and sisters, even though I am right next to them, they always have actions that should have been done in their own room, as a boy who is in puberty, it makes me feel extremely desire. My sister-in-law at home often wears very sexy clothes, which makes my lust rise more and more.
