Living with a spoiled sister-in-law

I moved to live with my brother and sister-in-law Nao Jinguji to make it easier to go to school and work. Living with both of them, I often have to witness the passionate scenes of my brother and sister. Even though I'm right next to them, both of them still do things that should be done in separate rooms. During puberty, it made me feel extremely desirable. My sister-in-law at home often wears very sexy clothes, making my desire increase more and more.
