Terra Mizu's step-brother comes in to ask his step-sister for a favor. She is reluctant until he offers to pay her $10 for helping him. He rolls in a device which he claims will read her mind. She sits underneath it and he plugs it in. They switch bodies and she wakes up in her step-brother's body; and him in her body. Oh no! She runs off to the bathroom. Meanwhile he hijacks her body and explores his new female figure. He feels his step-sister's body up, and masturbates. But doesn't finish up quite in time before his step-sister catches him using her body for naughty things.
