Caio Vilar, the curious, young student, can't help but stare at his professor's bulge. One day, after class, Flavio Bear, the burly, hairy teacher, catches Caio's lustful gaze. He invites Caio to his office, where he reveals his monster cock, thicker than any Caio has seen. Caio's eyes widen, but his mouth waters. He eagerly sucks Flavio's cock, taking it deep into his throat. Flavio, enjoying the show, decides to give Caio a real lesson. He turns Caio around, bending him over his desk, and pushes his thick, bare cock into Caio's tight, virgin hole. Caio gasps, but Flavio doesn't stop, fucking him hard and raw, giving Caio a lesson he'll never forget.
