Layla Jade vs Vivian Valentine

Layla Jade is one wild, wild cocksucker who knows how to work magic with her hands. Fighting her on the ring for the cocksucking championship is the vixen Vivian Valentine, who enjoys getting her mouth rammed by long, hard dicks. The girls have half an hour to suck 8 or 9 well-hung guys. Which one will out-suck the other?
