Soft-spoken Mahogany Masters chats for a few minutes with the XL Girls studio manager. The conversation gets around to her 42K-cup bras. They are gigantic. She hands Mahogany one of her pink bras and requests to see her put it on by a full-length mirror. The mirror lets us see that Mahogany has quite a booty also. This bra has five hooks for obvious reasons. After we study Mahogany's way of hooking on her bra, we get to see how Mahogany puts it through very rigorous testing. There's lots of bouncing going on in this very educational bonus video. Mahogany Masters will make you lose your mind.
