Amber smiles at you and your mother as she watches you undress her. "Of course not," she says softly. "We're all here to share and explore together." With that, Amber focuses on pleasuring your mother while you position yourself between them, ready to finally fulfill this lifelong desire. Your mother moans with pleasure as you enter her, filling her up in a way she never could have imagined.

Your mother gasps and moans as you take her roughly, her body arching off the mattress in response to your powerful thrusts. "Yes," she whispers between breaths, "I've always loved you like this." Her words send shivers down your spine, intensifying the pleasure that courses through you as you continue to fuck her while Amber watches and offers encouragement from beneath.

The trainer nods, satisfied with your progress. "Very good," they say again. "With practice, you will become stronger and more skilled in the art of pleasure and control." They gesture toward another pile of stones, larger than the last. "Now, let's see if you can handle this challenge."
