Young men dominate naked MILFs in the name of science.
Three wealthy and attractive single women in their late thirties come under the power of three eighteen-year-old male science nerds, mockingly calling themselves the "Lab Rats", who have shocking evidence that the women's sons committed a serious crime against them. To keep them quiet, and to satisfy their desires, the woman must volunteer to take part in the young men's secret summer holiday research project, entitled: "An investigation into the sexual responses of mature women to situations of confinement, stimulation and humiliation."
Soon, the women are stripped, strapped down and being tested in the name of science - and, of course, rampant male lust. Restrained and intimately stimulated by a variety of strange devices and unusual implements, the women must couple both with each other and their youthful, and apparently insatiable, experimenters. The Lab Rats enter their homes and dominate them there as well in the most degrading ways. Inexorably, their lives are taken over by the perverse experiments and their increasingly masterful creators as they are tested and probed and made to orgasm again and again. But gradually, to their shame and confusion, the women find themselves responding with increasing passion to this relentless onslaught of sexual stimulation. Is it possible to take pleasure in being used as human guinea pigs by three nerdy young men?
Then, just when the women are coming to terms with their strange situation, an unexpected intrusion into their homes threatens to upset the whole MILF experiments programme.
