Sasha sauntered into the living room, her tight dress hugging her every curve. She could see her step-son sitting on the couch, his eyes glued to his phone. She smirked, knowing he wouldn’t be able to resist her for long. “Hey baby,” she purred, plopping down next to him on the couch. “What are you up to?” He looked up at her, his eyes widening as he took in her barely-there outfit. “N-nothing, just browsing online,” he stammered. She chuckled, reaching over to run a hand along his thigh. “Is that so? Because it looks like you’ve got something else on your mind.” He shifted uncomfortably, his cock already starting to strain against his jeans. She licked her lips, leaning in closer. “I bet you’re thinking about Mommy’s big cock,” she cooed, giving his bulge a squeeze. “I bet you’re dying to be used as my personal fucktoy.” He moaned, his hips bucking up into her touch. She grinned, reaching down to unzip his fly and pull out his hard cock. “Fuck, look at this pretty little dick,” she purred, stroking him slowly. “I can’t wait to ruin it with my own big cock.” He whimpered, his body shaking with need. She just laughed, giving his shaft a sharp smack. “Get on your knees,” she demanded, standing up and pulling her dress off over her head. “Mommy’s going to fuck your tight little hole raw.” He scurried to obey, dropping to his knees in front of her and burying his face between her ass cheeks. She moaned, reaching down to grab a fistful of his hair. “That’s right, worship Mommy’s ass,” she growled, grinding against his face. “Get it nice and wet for my big cock.” He lapped and slobbered at her hole, his tongue probing deep inside. She groaned, pulling him back and shoving him onto the floor. “Beg for it,” she demanded, strapping on her massive cock. “Beg Mommy to ruin your ass with her big dick.” “Please Mommy,” he whined, presenting himself on all fours. “Please fuck my tight little ass with your big cock! I need it so bad! I’m your little fucktoy, please use me!” She smirked, pressing the tip of her cock against his hole. “That’s right, you’re Mommy’s little bitch now,” she purred. “Now take it like the nasty slut you are.” She slammed forward, burying herself to the hilt in one brutal thrust. He screamed, his body convulsing as she began to pound into him mercilessly. “Fuck yes, take it you little fucktoy,” she panted, gripping his hips hard enough to bruise. “Take Mommy’s big cock like a good little slut!” She pounded into him, the sound of skin slapping against skin filling the room. He sobbed and moaned beneath her, his body shaking with each brutal thrust. “That’s right, scream for Mommy,” she snarled, reaching around to grab his own cock. “Cum while Mommy fucks your tight little ass!” He screamed, his body convulsing as he shot his load all over the floor. She groaned, slamming into him one last time before burying herself deep and flooding his ass with her own release. “Fuck yes, take it you little fucktoy,” she panted, collapsing on top of him. “Mommy’s gonna use you as her personal fucktoy from now on.” She stayed buried inside him as they came down, his hole fluttering around her softening cock. She knew he was ruined for any other woman now, his ass permanently wrecked by her massive dick.
