Cassie and Diana are lovers. Cassie surprises Diana with the proposal to shoot a porn movie together. It's not your average porn movie. It's armpit porn where Cassie licks Diana's armpit first. She also teases her with her fingers and kisses her. Diana looks into the camera to make sure the shot is good. Diana is ecstatic as she cums. Then Cassie is next. Cassie's armpits are a bit ticklish, so Diana uses her fingers more than her tongue, but Cassie manages to cum. They end up cuddling, and who knows how it will continue from there...
