Mistress Nika, her eyes gleaming with dominance, orders her bound submissive to arch his back. She traces intricate patterns on his chest, her fingers pausing to tease and pinch his nipples. Nika's touch is a dance of pain and pleasure, her nails leaving red welts as she scratches and pinches. She leans in close, her breath hot on his skin, as she takes one nipple into her mouth, sucking and biting until he cries out in a mix of agony and ecstasy.
