Cat flaps = empty tits
Cellophane Cat Flaps = extremely empty tits
The tits are literally just skin and the skin is so thin it clings to the chest like Cellophane
These are not flat chested tits these are ones buoyant decent sized boobs that have deflated through child bearing and breast feeding
Those aren't just cat flaps they are Cellophane cat flaps ... like seriously empty. They could not be any emptier
