Kenna brings her friend Blake Eden to new exercise class: Sit And Spin! Blake Eden can't believe her eyes when she sees the instructor Karlie Montana pedalling and fucking a dildo at the same time. Blake Eden is nervous, but she's willing to give it a shot. First Kenna James and Blake Eden 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.
