The heavy steel chains rattled as Mistress yanked the bondage girl forward by her collar. "On your knees, slut. Ass up." The girl dropped fast, chains clinking against the concrete floor. Her wrists were already cuffed behind her back, ankles spread wide by a short spreader bar. A thick leather collar circled her throat, connected by another chain to a ring bolted in the wall. She couldn't move more than a foot in any direction.
Mistress circled her slowly. She wore tight black leather pants and nothing else on top. Her tits were bare, nipples hard. In one hand she held a heavy wooden paddle. "You've been begging for this all week. Now you're getting it." She brought the paddle down hard on the girl's bare ass. The crack echoed. The girl jerked in her chains and moaned. A bright red mark bloomed across both cheeks.
Another swing. Then another. Mistress didn't hold back. She spanked the bondage girl until her ass glowed deep red and her thighs shook. "Count them, whore."
"Five… six… seven…" The girl's voice broke on each number. By fifteen her ass was striped and burning. Tears ran down her face but her cunt was dripping onto the floor. Mistress reached between her legs and shoved two fingers inside her. "Soaked already. Pathetic little pain slut."
She pulled her fingers out and wiped them across the girl's mouth. "Suck." The girl licked them clean without hesitation. Mistress unbuckled her pants and stepped out of them. Strapped between her legs was a thick black dildo, already slick with lube. She pressed the head against the girl's tight asshole.
"Beg for it."
"Please, Mistress. Fuck my ass. Use your bondage girl. Chain me and wreck my hole."
Mistress grabbed the chain attached to the collar and pulled it taut. At the same time she thrust forward, sinking the strap-on deep into the girl's ass in one rough stroke. The girl screamed. Her body tried to pull away but the chains held her in place. Mistress started fucking her hard, hips slapping against the already sore ass. Each thrust shoved the dildo deeper. The chains rattled and jerked with every impact.
"Take it. That's what you're for." Mistress spanked her again while she fucked her, open-handed smacks timed with the thrusts. The girl's ass clenched around the thick cock. She was drooling, eyes glassy. Mistress reached under her and pinched her clit hard. "Don't you dare come yet."
She pulled out suddenly, leaving the girl empty and whimpering. Then she unlocked the ankle spreader only to reattach it wider. She shoved the girl's face down to the floor so her ass was completely exposed and vulnerable. The chain from the collar kept her head pinned low. Mistress lined up again and drove back in, deeper this time.
She fucked the bondage girl's ass in long, brutal strokes, one hand fisted in her hair, the other slapping her reddened cheeks.
The girl was babbling now. "Please… harder… use my ass… I'm your chained fucktoy…" Mistress gave her exactly what she asked for. She pounded her until sweat ran down her own chest and the girl's thighs were shaking uncontrollably. When she finally allowed it, the girl came with a broken scream, ass clenching tight around the dildo, cunt pulsing and dripping.
Mistress didn't stop. She kept fucking her through the orgasm, drawing it out until the girl was sobbing and limp in her chains. Only then did she pull out. She unlocked the collar chain, flipped the girl onto her back, and straddled her face.
"Clean it." The girl licked the strap-on clean without being told twice, tongue working over every inch. Mistress ground down on her mouth until she came too, thighs clamped around the bondage girl's head.
Later, after the cuffs came off and the chains were coiled away, Mistress pulled the girl into her lap and stroked her hair. The bondage girl nuzzled against her chest, ass still throbbing, body marked and used. "Good girl," Mistress murmured. "My perfect chained slut." The girl smiled, already half-asleep, already aching for next time.
