MASSIVE tits. Boobs of such grand proportions that they could knock someone out if the women possessing turns around too fast. You can hear the milk swooshing within the tits because there is so much extra space within.
Don't get too close when you surprise her, if she spins too fast and you're within range of the Mastodon Tits, they'll send you to the moon!
