Natalie Mars, the clinic's shemale doctor, is known for her kinky, dominant nature. Today, she's particularly hungry, her thick trans cock straining against her scrubs. Her assistant, a handsome, eager man, catches her eye. She summons him to her office, locking the door behind them. She orders him to undress, inspecting his body like a piece of meat. She runs her hands over his chest, pinches his nipples, then grabs his ass, squeezing hard. She spits on her hand, lubing up his ass, then shoves two fingers in, scissoring them open. He groans, his cock rock hard. She smirks, unzipping her pants, revealing her massive trans cock. She strokes it, slapping it against his ass, then plunges in, fucking him rough and raw, her heavy balls swinging, until she cums, coating his ass in her hot, sticky trans seed.
