Mamtamram's crimson lips curl into a smirk as she directs her submissive to the cross. Her eyes, hungry and intense, lock onto his rosy nipples, already hard with anticipation. She teases, flicks, and bites, each sensation sending jolts of electric pleasure-pain through him. The room fills with the symphony of his gasps and her muffled commands, "Beg for more, my pet." She obliges, twisting and pinching until his nipples glisten, raw and tender, a testament to her expert domination.
