i have a bit morbid joke for you:
The daughter asks for permission to go to the cinema and for the money for it.
The dad says you have to suck my dick for it.
Well, the daughter really want to go out, so she sucks her dads dick.
After she finished and sucked it up, she made a bad disgusting face.
The dad asks: whats up?
She: Your dick tasted like shit.
Her dad: Well, your brother also wanted to go to the cinema.
