During the coaching, Seth starts getting handsy with Anna and Charlotte seems into it, which surprises Anna. That's when Anna learns that they want her to have sex with Seth because of Charlotte's low libido!Anna is even more surprised but open, which leads to her having sensual sex with Seth while his doting wife guides them throughout. Charlotte is hands-on as she guides Anna's head to her husband's cock for a blowjob, his cock to her pussy to be fucked, and more. This is going to be a coaching class that none of them will ever forget as their cravings are finally satisfied.
