CJOD-077 [Uncensored Leaked] Sister Shiina Sora controls the ejaculation of her brother who is restrained and unable to move

A vacuum bed is a plaything made of rubber for compressing and restraining. Sora buys this vacuum bed that her shut-in brother has been researching and begins to confine himself in it. Unable to move and deprived of his sight, his body reacts abnormally to even being touched in an unpredictable manner. Under these circumstances, he is repeatedly teased to the brink of orgasm, and even after ejaculation, his actions do not stop, leading to a massive ejaculation by the brother and two bursts of thick semen! A new sensation and new feeling of reverse SM where your sister controls all of your ejaculation!
