Sarah's submissive pleasure

Her master hears her moan and his ego swells. Sarah hangs there, bound tight, arms wrenched back, tits pushed forward. The gag stretches her jaw open, muffling every desperate sound she makes. She gives it up willingly. Hands hit her skin hard and quick. Pain blooms across her ass, sharp and immediate, and she takes it without pulling away. Every slap proves she belongs right there. The ropes don't give. Her big tits shake with each hit, and the wet ache between her legs only gets worse. Sarah keeps offering herself anyway, letting the pain turn into something filthy and sweet. She isn't going anywhere. She doesn't want to.
