[JUL-164] Backtooku's Bunk Bed Adhesion Mother-in-law Incest Amano Tsubaki

For a month, our brothers had been playing a lot of time since my father remarried to a beautiful and gentle woman named Tsubaki-san. It has been conscious as a woman before it is mother. However, i was irritated by Tsubaki,who loved only his brother who was all-purpose in study and sports. The relation between the big brother and Tsubaki's was a relation which stole father's eyes, heated up, and took a bath together before one is aware. One night, Tsubaki sneaks into the bunk bed where our brothers sleep.
