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 living with his parents and younger sister. One day, he witnesses his sister falsifying test results. Seeing this as a good blackmail opportunity, he orders her to obey him as a maid if she doesn't want him to expose the falsification while their parents are away. His innocent sister, not wanting to be exposed, agrees... He toys with his overly sensitive sister, continuing the punishment game after each orgasm... Momo-chan's submissive face is shown from a completely subjective perspective, and all the ejaculations are facials!!
