Tomb Raider TF/BE
I don't imagine this an original idea but I figure a historian looking at an ancient voluptuous statue that transforms her into the classic and curvy Lara Croft?
A blond historian is in her office looking at this strange statue, unsure of it's era or even original place of origin. As she studies it she begins to sweat, getting dizzy and beginning to lose focus as to what she's writing. She starts to break into a british accent now and again, not sure why as she isn't doing it purposefully. Suddenly a sharp pain in her chest brings her breasts heaving and stretching out of control. Her terror continues as the buttons on her blouse pop off one by one, revealing a green tank top she was wearing as an undershirt for the day. She removes the remnants of her blouse to relieve the heat and see what happened to her once small breasts, now turned small melons placed on her chest. They feel so heavy, soft, bouncy, foreign from what she's used to. Her hair then goes from blond to brown, growing longer as it goes darker. As her unexplained changes continue the british accent stays and she can't go back to her normal voice. She places her hands to her head, trying to keep her head together as everything goes hazy, then her nails elongate, glossy and manicured. As her hands go down, the historian is gone, turned into the legendary tomb raider, Lara Croft. She picks up nearby sunglasses and leaves the office, off to find another mysterious artifact.
