Gorgon. Futa Monster Girls, #20

Knowing she needed to help face the darkness plaguing their lands, Briana joined a band of rebels, eventually going on a daring raid to steal an ancient relic from the clutches of the dark sorcerer, Malakai. She couldn't have expected what followed. Her escape led her to an ancient temple where a mysterious gorgon with pale skin and serpentine allure saved her from her pursuers, only to knock her unconscious.
Captured and chained, Briana discovers she is immune to the gorgon's petrifying gaze - a discovery that makes the dark monster far more interested in her. Briana isn't confident that interest is something she might be able to survive.
