While I love a girl with a curvy rump, in porn the movies with that theme are almost always anal obsessed. Fortunately this one is different. The girls get extended opening sequences to show off their bodies, which includes coating their butt in oil or soapy water. It makes a big difference over just jumping right to the sex.
Rachel Starr, who has the best butt in the business, is in all her glory here. Her tease is in a bathtub, moving in and out of the water so you can see water and suds cascade down her perfect ass while she does her trademark rump shake. Then you see her nearly as impressive front, with those full lips, well done implants and the purple contacts she wears here. The first time I watched this I didn't even make it to the actual sex scene. The sex scene itself is well over 20 minutes and by itself is reason to rent this.
The last girl in this film, Becca Bay, is very pretty and gives a standout performance. The rest are also very good but this will be a novel if I describe everything. This one should be high on your list, and I had trouble parting with it despite having become a bit of a porn snob from watching so much.
