Ashley Graham needed some quick cash, so she volunteered to test some new massage oil with Tommy Gunn and the scientists over at Turtlesburg Research. First up is the clothing test, where they hose her white t-shirt down, making her big natural tits peek out through the wet fabric. After that come the skin and friction tests, where Tommy Gunn has to rub some of the experimental oil over every inch of Ashley Graham's hot body. Finally comes the penetration test, where a horny and eager Ashley Graham finally gets to wrap her supple lips and wet pussy around Tommy Gunn's big fat cock!
