Two people, a mother and a big-breasted J*, moved in next to the cheap one-room apartment where I live. One rainy day, Hana-chan was wet, so she invited her into the house. From the day I had sex because I couldn't control my excitement because of my big boobs that I could understand even with my clothes on, my house became a libido-relieving room! Because I can't even masturbate in the room where I sleep with my mom... I'm immersed in J ○ who has too strong sexual desire, and if I have time, I'll be treated for sexual desire (crying).
