Hono has started to stay home because of her failure to take the university entrance exam. Except for going back and forth between the house and the convenience store, I used to spend every day indulging in masturbation on the net and erotic comics, but I noticed my younger brother, "I want to lick Ji-Po about once before I die." Yuta, a gentle younger brother, responds with the intention of only once, "If your sister gets well with it ...". However, my sister who was absorbed in the taste of Ji-Po began to sneak into her brother's bed almost every night, and Yuta looked back at the smile of her sister who gladly drank sperm with mixed feelings. …. However, one day, I witnessed Yuta calling her at home and having sex, and Hono's emotions were greatly shaken. Even though I'm a younger brother, I'm not a lover, but I just wanted to see Ji-Po ... The intense jealousy and excitement I felt for the first time. "I can't forgive Yuta's Ji-Po is mine!" Is this sexual desire or affection?
