Like a helicopter, but instead of roaters there are titties.
Look at that tittycopter flying through the air.

Tits moving in a rhythmic circular motion similar to that of a helicopter rotor when fucked. Most commonly seen in larger natural breasts it can be induced in smaller breasts provided enough force is applied. Often seen together with the ripple effect.
I was so mesmerized by your Mom's Tittycopter that I feel off your race-car bed.
