She knelt naked on the cold concrete floor, wrists already cuffed behind her back, the leather collar tight around her throat. Her mistress stood over her in black boots and nothing else, crop in hand. "Spread those knees wider, slut.
Show me that cunt."
The command hit like a slap. She obeyed instantly, thighs parting until her pussy lips opened, already slick and swollen. Mistress circled her slowly, the tip of the crop dragging across one hard nipple, then down her stomach, stopping just above her clit. "You don't come until I say. Understand?"
"Yes, Mistress."
The crop snapped down on her inner thigh. Sharp sting, then heat. Another on the other thigh. She gasped but kept her knees open. Mistress grabbed a fistful of her hair and yanked her face up. "Tongue out." She pushed two fingers into the wet mouth, fucking it deep until spit ran down her chin. "That's how you'll take my strap later. Like a greedy little whore."
Mistress hauled her up and bent her over the padded bench. Ankles were strapped wide apart, wrists clipped to the front so her ass and cunt were completely exposed. A thick plug was shoved into her pussy without warning, stretching her fast. She moaned loud. The crop landed across both ass cheeks in quick succession, ten hard strokes that left her skin burning and her cunt clenching around the plug.
"Count them."
She did, voice shaking. By the last one her thighs were trembling and her clit throbbed untouched. Mistress pulled the plug out and replaced it with three fingers, pumping hard and fast, thumb grinding her clit in rough circles. "You want to come already? Too bad." The fingers withdrew. A heavier flogger replaced the crop, leather tails slapping wetly against her soaked pussy. Each strike made her jerk and drip.
Mistress finally stepped into the harness. The thick silicone cock jutted out, shiny with lube. She pressed the head against the sub's entrance and shoved in deep in one thrust. The stretch burned. She cried out, body rocking forward against the restraints. Mistress fucked her in hard, steady strokes, one hand gripping the collar, pulling her back onto every thrust. "Take it. This cunt belongs to me."
Sweat slicked their skin. The bench creaked. Every time the sub got close, Mistress slowed or stopped, leaving her empty and desperate. She begged, voice hoarse. Mistress only laughed low and dark, then pulled out and undid the ankle straps just long enough to flip her onto her back. Wrists stayed bound above her head. Mistress climbed over her face. "Eat."
She licked and sucked the swollen clit above her, tongue working frantically while Mistress rode her mouth. Mistress came with a growl, grinding down until the sub's face was soaked. Then she turned around, lowered her own dripping cunt onto the sub's, and started grinding. Their clits slid together, wet and swollen. Mistress reached down and pinched the sub's nipples hard while she rocked faster.
"Come for me. Now."
The orgasm ripped through her, thighs shaking, cunt pulsing against Mistress's. Mistress kept grinding through it until she came again, then collapsed forward, still holding the collar. She kissed the sub's forehead, voice softer for a moment. "Good girl. My perfect little fucktoy."
Later, after unbuckling the cuffs and rubbing cream into the marks, Mistress pulled her into bed and held her close, fingers tracing the collar she left on. "Tomorrow we do it again." The sub smiled against her chest, already wet at the promise.
