A subjective work where you can enjoy a sweet lover's time alone with your sister, Nanase Mia, who is a fan of all AV! "My parents aren't home today...///" I got a call from Mia, who was home alone, saying, "I want you to come over and play!" The most beautiful girl in the academy became my first girlfriend! The first H, which marks the beginning of graduating from being a virgin, starts from morning to night with 8 shots recorded in 7 luxurious corners! Completely subjective, you can monopolize your favorite girlfriend! All day long, you can do whatever you want with love at home!
