dad roulette
A husband gets his friends to all blow his wife at the same time. He uses a funnel to make it extra messy. The dad is whoever ends up with the baby.
My dad’s friends all stuck a funnel in my mom and cummed at once. Now my dad’s the dad.
My friend’s dad used a funnel and all his friends cummed in my friend’s mom.
My uncle’s friends all used a funnel and cummed at once in my aunt.
