As the last student leaves, busty BBW teacher Ms. Thompson lets out a sigh of relief. Her huge tits heave under her blouse as she starts to clean up. Suddenly, she hears footsteps. In walks a strapping young man, not a student, but a new janitor with a hungry gleam in his eye. He's seen Ms. Thompson's curves before and can't resist the urge to approach her. She's taken aback but as he reaches out, gently caressing her massive breasts, she feels a spark. His hands are rough, yet tender, and her pussy responds, soaking her panties. She gives in, letting him unbutton her blouse, revealing her gargantuan tits spilling out of her bra. He pushes her down on her desk, hiking up her skirt to find her panties drenched. He buries his face in her snatch, licking and sucking her clit until she's moaning loudly. Then, he stands, unzips his pants, and reveals his thick, long cock. Ms. Thompson eagerly takes it in her mouth, swallowing it whole. He fucks her face hard before turning her around and slamming his cock into her from behind, pounding her tight pussy as she claws at the desk. She cums hard, her juices dripping down her legs. He pulls out, strokes his cock a few times, and cums all over her back, leaving her panting and satisfied.
