A vacuum bet is a play tool for compression restraint made of rubber material. Sora buys this vacuum bet that her withdrawal brother was investigating and begins confinement. The body reacts abnormally even if it is touched by unpredictable behavior while being unable to move and being deprived of vision. In such a situation, my brother repeatedly injects a large amount of male tide and shoots two thick sperms in an act that does not stop even after ejaculation! Reverse SM with a new sensation and new feel where all ejaculation is controlled by my sister!
