My Sister's Test - Amy Gross, Kara Hartley, Emma Alba, Ava Cash

Amy Gross and Kara Hartley test their stepbrother in a steamy shower encounter, soaping him up and taking turns on their knees. The scene moves to the living room where Emma Alba and Ava Cash join, turning the test into an oily foursome on an inflatable mattress. The girls trade places, riding and grinding until everyone is slick and spent.
