Xavier, the helpful stepbro, takes Donovan under his wing to teach him the art of edging and lasting longer. On their cozy couch, they begin with solo masturbation, Xavier demonstrating with his massive, uncut twink cock while Donovan watches, his own thick rod growing stiff. They move on to mutual masturbation, their fingers exploring each other's smooth, shaved bodies, paying special attention to their sensitive cocks and tight assholes. Xavier then shows Donovan the pleasure of ass-licking, rimming his eager hole before Donovan returns the favor, their taboo lust growing with each intimate touch.
