The weekend Serg was expecting to have at Professor Gianni's winter home has already descended into all-out cock lust, after catching the Professor and his step-son fucking, and sharing a flip fuck with Luciano in secret. Finally, the inevitable happens, with Professor Gianni clearly desiring his handsome student just as much as Luciano, the two are quickly engaged in a feast of cock sucking. The feast only grows when Luciano interrupts the predictable exchange, starting with a jerk off to the live show, but soon pulling him into a wild threesome! Student Serg finds himself in the best position, on his back with the Professors cock wedged in his hole, while Luciano rides his uncut raw dick! A switch around places Luciano in a familiar position, with his dick inside their guest while Professor Gianni fucks him raw from behind! Student Serg soon gets the most fulfilling lesson, with both big cocks stuffed inside his ass, frotting away against each other, leading to a spitroasting that takes the three to a cum splashing finish to leave any man drained and happy.
