RCTD-643 A boyish girl at a girls’ school who seems like a prince!?

A popular girl had a secret she could never tell anyone: she was actually endowed with a large male organ. Her desires were strong, and she was obsessed with self-pleasure. Her younger sister, who attended the same school, also always helped her out. Then, at last, her secret was discovered by the girls at school. She became fully aroused through manual stimulation, was restrained and brought to climax with a toy, and ended up in a harem-like situation, completely captivated by her overwhelming virility.
