The nuances and positions in sex are probably shown most clearly in this movie. The beautiful girl Ichinosu and two tall, healthy guys have a threesome. With a childish and immature personality, meeting a young man with extensive lovemaking experience, it was difficult for her to endure. He even had very strong and decisive actions. Tying her hands and using large sex toys to help her pleasure herself, not to mention his healthy body and large penis made her continuously moan in pleasure.
