A mischievous glint in his eye, the doctor strips off his coat, revealing a chiseled torso. He orders the twink to turn around, and the young man eagerly obliges, presenting his slender ass. The doctor spits on his fingers, lubing up the tight hole before pushing his thick cock inside. The twink moans loudly, his body tensing as the doctor begins to pound him relentlessly. The doctor, a sadistic smirk on his face, reaches around to stroke the twink's cock, bringing him to the brink of orgasm. He then pulls out, flipping the twink onto his back, and fucks him missionary-style, filling him with hot cum in a creamy, satisfying breeding.
