[UNCENSORED-LEAK] MIDA-651 For three days while our parents were away, I punished my younger sister, who had a premature ejaculation, by turning her into my personal orgasm-controlling maid. (Inoue Momo)

An older brother lives with his parents and younger sister. One day, he witnesses his sister falsifying test results. Seeing this as a perfect blackmail opportunity, he orders her to obey him as a maid if she doesn't want him to expose her tampering while their parents are away. His innocent sister, not wanting to be exposed, agrees... He continues to tease his overly sensitive sister, punishing her whenever she orgasms... A completely subjective view of Momo-chan's submissive face...
