Service Day: Tickled

House slave Sin fucked up. Forgot her cuffs. Now she pays with her body. She stands naked except for her long black hair brushing against her heavy tits. Her wrists and ankles are strapped tight to the wooden frame, legs spread wide, ass exposed. The Dom circles her slowly, letting the tension build. Then the fingers attack—digging into her ribs, under her arms, across her belly. She thrashes and screams but the straps hold her firm. Every jerk makes her massive tits bounce. He moves behind her. Two thick fingers push straight into her asshole without warning. Sin grunts. Her hole stretches around the intrusion while the tickling never stops on her front. He works her ass open, then swaps to a bigger plug, forcing it deep. She moans and gasps at the same time, her body caught between pain, laughter, and the filthy pressure in her guts. The tickling turns meaner—feathers on her nipples now, then bare hands again on her sides. She twists, but every twist drives the plug deeper. Her voice cracks. Sweat runs down her spine, sliding over the curve of her ass cheeks. The Dom laughs once, low and dark. She keeps forgetting. He keeps remembering how to make her remember.
