Maria's ample bosom heaves with desire as she leans over Juan, her voice husky with lust. 'Today, we learn about the body,' she purrs, tracing his hand over her curves. She guides his fingers to her nipple, teaching him to roll and pinch, eliciting gasps from her lips. Her hands roam his body, exploring his growing erection through his jeans. 'Now, Juan,' she whispers, 'it's time for you to practice.' She unzips his pants, freeing his hard cock, and teaches him the art of breast fucking, her tits bouncing and jiggling as she rides his length, the wet sounds of their union filling the room.
