A calligraphy teacher who usually teaches calligraphy to children makes her AV debut!! This naughty older sister applied for the film herself, saying that she likes watching AV and has an interest in sex. Just like her gentle and cute appearance, when she takes off her clothes, her naked body looks white and soft. However, when a raw cock is inserted into her, she changes completely!! The difference from her gentle mode is amazing! She has an intense orgasm and desperately wants a cock!! The raw teacher is exhausted, with the sperm that was ejaculated inside her spilling out of the inkstone in her pussy...
