Bound in intricate shibari ropes, the submissive squirms, his cock throbbing with anticipation. His mistress, clad in latex, watches him struggle, a cruel smile playing on her lips. She approaches, her heels clicking on the hardwood floor, and takes his cock in her hand. She strokes him, her touch feather-light, teasing him mercilessly. She leans down, her breath warm on his cock, and whispers, "You will cum when I say so." She brings him to the edge, his cock pulsing in her hand, only to back off, leaving him breathless and frustrated. This dance continues, her touch alternating between soft and firm, until finally, she allows him to cum. But it's not a release. She takes his cock in her mouth, sucking him dry, her long nails digging into his thighs, marking him as hers.
