Mei Kosaka, who is making her lesbian debut in this film, has been learning ballet since she was a child, so her supple body is beautiful and flexible. Her first lesbian partner is Ruri Hoshijima, a serious rhythmic gymnast who has competed in the National Athletic Meet. When two 'flexible girls' get entangled... you can see some incredibly intense lesbian sex! Covered in saliva and oil, they pile their flexible bodies together, attack each other's pussies in an I-balance, and have double-headed dildo sex that makes them arch their backs and reach a Shachihoko-like climax! These two are really amazing...
