Overview:Light Southern and director Michelle Flynn bring us the 4th and final Volume of Momentum. This ultimate chapter is powerful, provocative and even humorous, focusing on girl power and male masturbation. Flynn moves away from the purely lesbian theme of the last chapter, focusing on female pleasure in heterosexual scenes, before dropping us at the foot of a dreamy waterfall for one final, all-female fantasy. Like the rest of the series, Volume 4. is fascinatingly varied, diverse, empowering and engaging, with retro aesthetics and character chemistry which leave us desperate for her next endeavor.
