Your daughter, Sora-chan, is a bright and energetic high school girl. However, she's in her rebellious phase. When friends come over for sleepovers, age-appropriate girls gather, making the dad feel instantly uncomfortable. Unfortunately, these girls are extremely interested in sex, so when they conduct a serious development check, their engines rev up, and they end up sucking on adult penises. Due to their overly clever schemes, I end up having sex with my beloved daughter without using a condom.
