Alix is so fed up with her husband's jealousy and insecurities that it pushes her away- and right into the very capable arms of her personal trainer, Rob, whose skills are solid (check that magic trick with the shoe disappearing at 4:14). Rob has clearly been doing his job because these two have the strength and stamina for days as they tear into each other for 12+ minutes. Ah, 10/10 to these hotties.
