Mark slammed the front door shut behind him and found his mother in the kitchen, still in her work blouse and skirt. "On your knees, Mom," he said, voice low and rough. She dropped without hesitation, eyes already glassy with need. He pulled the thick black collar from his pocket, the one with the silver ring in front, and buckled it around her neck while she stayed perfectly still. The leather hugged her throat snug. "That's better. My free-use mom, collared and ready."
She licked her lips. "Use me, baby. However you want."
He unzipped and fed her his cock in one thrust, gripping the collar ring like a handle. She gagged wetly but took it, throat working around him while spit ran down her chin onto her blouse. He fucked her mouth hard, balls slapping her jaw, until he pulled out and hauled her up by the collar. "Bend over the table."
She obeyed, skirt shoved up, panties yanked aside. Mark drove into her soaked pussy in one stroke, the collar chain jingling with every slam. "Fuck, this cunt's always dripping for your son's dick," he growled, pounding deep while his fingers hooked the collar from behind, pulling her back onto him. She moaned loud, pushing back, ass rippling. He reached under and rubbed her clit fast and mean until she came hard, walls squeezing him.
He didn't stop. He flipped her onto her back on the table, legs spread wide, and fucked her slower but deeper, watching the collar move with each thrust. "Tell me whose slut you are."
"Yours," she gasped. "Your collared mom slut. Use this pussy all day, every day. Fill me up."
Mark leaned in, biting her neck above the leather while he pounded faster. Sweat slicked their skin.
He pulled out, spun her around, and bent her over again, this time pressing her face to the wood as he took her ass with spit and steady pressure. She cried out but pushed back, taking every inch until he was balls-deep in her tight hole. He railed her there, collar gripped tight, dirty talk pouring out. "Gonna breed this ass next. Gonna keep you collared and leaking my cum all week."
She came again, shaking, and he followed right after, pumping thick loads into her. He stayed inside until he softened, then pulled free and watched his cum drip down her thighs. He clipped a short leash to the collar ring and led her to the couch, where he sat and made her ride him reverse, the collar tight in his fist again. She bounced on his cock, tits bouncing, until he yanked her back against his chest and came a second time, filling her pussy while she begged for more.
Later, still collared, she cooked dinner naked except for the leather around her throat. He fucked her again against the counter, slow and grinding, whispering how she was free to use whenever he wanted now that she wore his mark. She came on his fingers, then again on his cock, promising she'd stay collared for him forever. They ate together on the couch afterward, her head in his lap, his hand resting on the collar, both of them already planning the next round.
