In a cramped, dimly lit classroom, Rubia, the insatiable teen, has her professor right where she wants him. She's been teasing him all session, her big ass swaying hypnotically as she walks, her low-cut top revealing just enough cleavage to drive him wild. As he leans in to help her with a problem, she leans back, her ass pressing against his crotch. He freezes, trying to maintain his composure, but she can feel his cock stirring. She smiles, knowing she's got him. She stands up, turning to face him, her hand reaching out to stroke his now obvious erection through his pants. "I think I need some extra credit, professor," she purrs, her eyes locked on his.
