In the sterile confines of her office, Nina Devil, a white-skinned brunette with barely-there tits, thinks she's alone until her professor, Stif Mat, walks in. Caught with her hand down her pants, she expects discipline, but instead, he offers her an education in anal pleasure. Nina, a curious teen, eagerly sucks his cock, her eyes watering as she takes him deep. Bent over her desk, she feels his thick, hard cock push past her tight asshole, her body tensing before relaxing into the intense pleasure of being filled and fucked.
