One of the strongest new series JKP has to offer, Unbelievable Sex enters phase three of its sex-filled existence and doesn't let up one bit.

We start with Cindy Crawford get dick-bashed by Lee Stone, a man who enjoys hoisting his lady in the air and screwing her standing up. Gravity defying, to be sure.

Cut to a back-to-back pair of girl-girl romps. First, Charlie Lane and Ashton Moore do it by the pool, sticking dildos in each others mid-section and squealing like stuck pigs as they writhe in ecstasy from getting fingered and licked. Then Cindy takes on Jenna Haze and Brittney Foster in a threeway bout to the finish. They, too, employ vibes and dildos, and much spit is traded as they slurp puss and French kiss.

Cindy returns with Cherokee for yet another girl-girl romp but are soon joined by Nick Manning, who jams his cock into both their mouths and pussies. Plenty of mouth-to-vag ensues.

A sloppy, anal threeway between Ashley Blue, Trent Tesoro and Joel Lawrence is the last exchange here and the least exciting.

Buyers beware, the cast on the box is not in the film and vice versa. This is billed as an Alexis Amore vehicle, but she ain't even in it.
