The beautiful and sexy older sister and her lucky younger brother. Today I will introduce to you a sex film from Japan. The story revolves around incest. Eimi is a swimsuit model, and she decided to go back to her hometown to visit her parents during her few days off. She also reunites with Satoshi, but it seems that he has something to say. When she presses him, she learns that he is often teased by his friends for having a swimsuit model as a sister, and he still doesn’t have a girlfriend. To teach her younger brother what making love is, Eimi wants to sit down and explain to him how to make love, but Eimi's body and beauty do not allow him to stop. He holds her and forces her to 'make love' with him.
