Speed bump bouncing 

When you take a girl with big titties that
you fancy for a ride in you're car and you
drive over speed bumps which makes
her big titties bounce and you watch in
the rear view mirror.

Anna. why do we always drive over
speed bumps?
Jez.. so ! can see you're titties bouncing up and down. It's called speed bump bouncing
