A kinky sub, clad in fishnets and heels, is tied up and left vulnerable. Her dominant takes full advantage, shoving a thick gag into her mouth and tying it tight. He runs a finger along her ass crack, pausing at her tight hole. She writhes, begging with her eyes. He smirks, pushing his cock into her ass, filling her completely. He fucks her roughly, holding her hips, slapping her ass, making her take it all. He pulls out, letting her catch her breath, then forces her back down, fucking her hard until he cums all over her back, marking her as his.
