A nervous but eager new sub, clad in lacy pink panties, presents his virgin asshole to his Mistress. She teases him, running her fingers along his butt crack, making him squirm. She lubes up a pretty pink plug and gently pushes it against his tight hole, coaxing him to relax. His asshole stretches to accommodate the toy, and he gasps at the intense, new sensation. His Mistress smiles, pleased with his progress, as he bounces on the plug, his big ass jiggling.
