Kenna James brings her friend Blake Eden to the new exercise class, Sit And Spin. Blake can’t believe her eyes when she sees the instructor Karlie Montana pedalling and fucking a dildo at the same time. Blake is nervous, but she’s willing to give it a shot. First Kenna and Blake slobber all over their dildos to get them nice and wet, then they slide them into their pussies and start pedalling. After some intense orgasms, the instructor has them cool off and stretch on the mat, rewarding her students’ good workout with a nice lesbian threesome!
