She is waiting for his return at her boyfriend's house who lives alone. "I'll be late tonight," he called. I had no choice but to take a shower first and wait for my return. After showering and changing into loungewear, the door suddenly pops open! There's an old man I've never seen before! Involuntarily, I shouted, "Who!?" Close the door once. The true identity of the uncle was... what a boyfriend's father. The father, who has a bad habit of women, was disgusted by his mother, and happened to visit his son at this timing. I closed the door once, but I couldn't get the young girl's body out of my mind while she was changing clothes. Resolve to open the door again. A father whose reason has flown into a beautiful body attacks him despite being his son's girlfriend.
