A woman is not a real woman unless she can get off with her anus! This is a 4-hour work that uses various toys to develop anal sensitivity. Three beautiful women appear in this work. The first is Koyuki Amano, who is tall and slender like a fashion model. Her calm and mature aura makes her a cool beauty. When she was 24 years old, she experienced her first anal fuck with her boyfriend at the time. Since then, she has had several experiences and has grown to the point where she says anal feels better. Koyuki's anus is violated so hard that brown dirty juice leaks out, and she is brought to climax many times. The second is Kubo Rira, who has only had anal sex once. She is still a fresh 23-year-old, but her body is quite sensitive. However, her first anal experience is only painful, so by combining it with an electric massager attack on her clitoris, she gradually awakens her anal pleasure. The third person is Hotaru Mori, who is only experiencing anal for the third time, but is attracted to anal play due to her natural masochistic tendencies. Since she loves abnormal play to begin with, she decides to take her time to play with her anus. As she is made to walk around with an anal plug inserted, her sphincter is stretched before you know it. Finally, an extra-thick dildo is inserted in her ass, exposing her lewd behavior as she writhes in ecstasy... Enjoy the embarrassing anal training documentary of three different people.
