A Russian coed, hungry for extra credit, finds herself in her teacher's lap, his hardness straining against his pants. She unzips him, her small hand barely fitting around his thick, veiny cock. Her inexperienced tongue licks tentatively at the tip, gathering the pre-cum. She opens wide, taking him into her warm, wet mouth, her cheeks hollowing as she sucks enthusiastically. The teacher's groans of pleasure guide her, encouraging her to take more, to go deeper, until she's a gagging, drooling mess, but she's loving every hardcore moment of her lesson.
