In the dimly lit confines of his study, the professor leans in close, his voice a low, rumbling growl as he initiates his student into the dark art of anal pleasure. His fingers trace the curve of her spine, her breath hitching as they dip lower, teasing her asshole. He slides a sex toy into her, his voice a soothing, guiding presence as she adjusts to the foreign sensation. His hands grip her hips, pulling her back as he sinks into her, his cock stretching her tight hole. He sets a slow, steady rhythm, his voice never wavering, even as his grunts of pleasure fill the room. The audio landscape is filled with the wet sounds of their bodies joining, the creaking of the chair, and the soft, urgent moans of the student, lost in a world of new, intense sensation.
