Collin Lust, the curious and adventurous stepson, sneaks into his stepdad's room, finding Markus Kage watching gay porn. Intrigued, Collin watches over Markus' shoulder, his cock hardening. Markus notices, turning to Collin with a lustful grin. "You like what you see, son?" he asks. Collin blushes, nodding. Markus pulls him close, kissing him roughly. They undress each other, Markus' massive body contrasting with Collin's slim frame. They sixty-nine, each exploring the other's body, before Markus pins Collin down, fucking him roughly and relentlessly, his huge cock stretching Collin's hole. Collin cums untouched, his body convulsing as Markus continues to pound him, eventually pulling out to cum all over Collin's face.
