you catch your sister doing something suspicious, she won’t fess up but eventually you get it out of her. This random object is magic, and makes wishes come true? LMAO yeah right, god your sister is an idiot. If it was real then this would actually work “i wish you’d moo and pretend to milk your fat tits”……uh oh!! You wish your sister into doing and saying humiliating and naughty things, making her suck your cock and beg for it in her ass!! at the end you have her beg for a load on her fat tits
