ฉันเจอไดอารี่ของลูกพี่ลูกน้องสาวขี้อายและค้นพบความลับทางเพศทั้งหมดที่เธอเขียนเกี่ยวกับฉัน

One day I was resting peacefully on the couch until my stepsister came to wake me up and ask me to leave the furniture because she needed to do something. When I go to the room after she woke me up, I discover that she has her personal diary in a cushion on her sofa. When she leaves I read and discover that she writes many sexual and hot things about me and I fuck her in exchange for keeping the secret.
