An inexperienced pair, hungry for new sensations, decides to indulge in the taboo. She's nervous but excited, her heart pounding as she prepares herself, fingers spreading her cheeks wide. He watches, his own excitement growing, as she lubes up and tentatively presses a finger inside. His cock aches, throbbing as he strokes it, waiting for his turn. When she's ready, she turns to him, and he takes over, his hands shaking slightly as he guides himself into her. They gasp together, the sensation intense and new, as they begin to move, finding a rhythm that's all their own.
