The Black Widow has been the test subject of a brand new serum from S.H.I.E.L.D. There are, however, some very unexpected results. Natasha's tits swell in size, and her libido is racing harder than ever before. She lures the doctor into a meeting to discuss the effects, but quickly seduces him by teasing her hands all over her curvy body. She gulps down his cock, telling him all the while how badly she needs him and his cum all over her tits. She finishes him off with her tits until he absolutely covers her massive chest in hot cum that drips down her body. This video includes so so so much dirty talk and begging.
