The professor's eyes scan the classroom, settling on her nervous student. With a predatory smile, she approaches him, her every move accentuating her curves and the impressive bulge in her pants. She sits him down, her transsexual allure captivating him. She unzips her fly, revealing her hard, veiny cock. She strokes it in front of him, then guides his hand to follow suit. He hesitates, then wraps his fingers around her shaft, feeling its heat. She stands, turning around and bending over, revealing her ass. "You know what to do," she purrs, and he tentatively begins to lube up her eager asshole, preparing it for the intense anal fucking that's about to commence.
