micro-titties

Extremely small female tits. Differs from the flat-chest in that while a flat-chest has zero percent breast tissue (just nipples on a chest essentially), micro-titties do possess some visible breast tissue, but a very insufficient one.

No man, Madison is not flat chested, her clothes just hide her micro-titties.
