When Markus Kage's stepson, Collin Lust, is feeling down, Markus steps in as more than just a dad. Starting with a tender conversation, Markus listens and consoles, but the tension is palpable. As Collin's voice quivers, Markus can't help but notice the bulge in his son's pants. Gently, he moves closer, his large, strong hand resting on Collin's thigh. The touch ignites a spark, and soon, Markus is swallowing Collin's big, hard cock, his experienced mouth working the length. Collin moans, his eyes rolling back, as Markus expertly pleasures him. Flipping Collin onto all fours, Markus lubes up and slowly pushes into his son's tight, virgin ass, filling him completely. Collin gasps, his body tensing, but Markus' steady, caring thrusts soon have him pushing back, hungry for more. Markus' big dick stretches Collin's hole, his balls slapping against his son's as he pounds him hard, just like the doctor ordered.
