In a secluded classroom, a busty 18-year-old, her uniform straining against her ample bosom, makes a naughty promise. She'll let her partner lick her pussy if he behaves. He eagerly agrees, lifting her skirt to reveal her bare, wet slit. He dives in, lapping at her, his tongue circling her clit, making her squirm. She holds his head, grinding against him, her moans echoing in the empty room. When he can't take any more, he stands, his cock rock hard. She unzips him, taking him in her hand, guiding him to her entrance. He pushes in, stretching her tight pussy, fucking her hard, his balls slapping against her ass, until he can't hold back, pulling out to cum all over her big, heaving tits.
