Having a girl suck your penis vigorously while trying to hum her favorite song. While at the same time her sister is eating your poop from your rear end. While at the same time having a stuffed domo stare at you with a hole in it. At the climax while the man begins to jizz, he must yell switch in order for the sisters to switch their positions.
