Young man with big cock is lucky

A drooling Alexis Fawx was so excited to see his almost step-son, Zac Wild, at Thanksgiving. Before he left for college, they fucked all summer, and Alexis was eager to bang him again. So she was heartbroken when Zac arrived with his hot new girlfriend Kimmy Granger. Kimmy is a complete bitch to Alexis, which makes Alexis want to fuck Zac even more. Alexis seduces him behind Kimmy's back, but it doesn't take long for Kimmy to discover they're giving Alexis a run for her money in a sloppy and competitive threesome.
