In a dimly lit study room, Professor Carlos welcomes his eager pupil, Rodrigo, for an intensive one-on-one tutorial. As they delve into the intricacies of Rodrigo's thesis, Carlos' gaze lingers on the young man's lips, his mind wandering from academia to carnal desires. He leans in, whispering for Rodrigo to demonstrate his "research" techniques. Rodrigo, understanding the unspoken command, drops to his knees, unzipping Carlos' pants to reveal a throbbing erection. He tentatively takes the professor's cock into his mouth, earning a pleased moan from Carlos, who encourages him to take it deeper.
