The rest of the morning passed in a blur of nervous energy. Sarah tidied up the house, trying to keep her mind off what was to come. She took a long, hot shower, shaving every inch of her body smooth and soaping herself up until she was glowing pink.
By the time 2 pm rolled around, she was a wreck - pacing the living room in a skimpy little sundress that barely covered her ass, her pussy dripping with anticipation.
When the doorbell finally rang, she nearly jumped out of her skin. Taking a deep breath to steady herself, she went to answer it.
Marcus stood on the other side of the door, looking every inch the dominant male. He wore dark jeans and a tight black t-shirt that hugged his muscular frame, his skin glistening under the afternoon sun.
"Hello, slut," he greeted her, his eyes roving over her scantily clad form. "Ready to be a good little bitch for me?"
Sarah's knees went weak at his words, and she had to lean against the doorframe for support. "Yes," she breathed. "Yes, I'm ready."
Marcus pushed past her into the house without waiting for an invitation. "Good girl," he praised, reaching out to grab a fistful of her hair and yank her close. "Now strip. I want you naked and ready for me when I get there."
Sarah didn't hesitate, peeling off her dress and tossing it aside before reaching back to unclasp her bra. She let it fall to the floor, revealing her heavy breasts topped with rosy nipples.
Marcus's eyes darkened with lust as he took in the sight of her. "Fuck," he growled. "You're even better than I remembered."
Sarah felt a thrill of pride at his words, arching her back to present herself to him. "Thank you," she purred. "Now what do you want me to do?"
Marcus smirked at that, his hand drifting down to cup her pussy through her panties. "First things first," he said roughly. "I want you to bend over the arm of the couch and spread your legs. I want to see that sweet little cunt dripping for me."
Sarah didn't need to be told twice. She hurried over to the couch, positioning herself as Marcus had instructed. She could feel his eyes on her as she bent over, exposing herself completely to his hungry gaze.
"Mmm, look at that," Marcus purred, coming up behind her and running a finger along her slit. "So wet and ready for me already. Such a good little slut."
Sarah moaned at his touch, arching into him wantonly. "Please," she whimpered. "Please fuck me. Use me. I need it so bad."
Marcus chuckled darkly, landing a sharp smack on her ass that made her cry out. "All in good time," he promised. "First, I want you to suck my cock like the dirty whore you are."
With that, he reached down and unzipped his pants, freeing his massive shaft from its confines. It jutted out obscenely from his body, thick and hard and perfect.
Sarah's mouth watered at the sight of it, and she quickly turned around, dropping to her knees in front of him. She looked up at him with pleading eyes as she took his cock in hand, stroking it slowly.
"Please," she begged again. "Please let me suck you."
Marcus smirked down at her, tangling his fingers in her hair and guiding her head towards his straining erection. "Open wide, slut," he commanded.
Sarah obeyed without hesitation, parting her lips and sticking out her tongue as Marcus pushed forward, sliding his thick shaft into her waiting mouth.
She moaned around him as he started to move, fucking her face with deep, powerful thrusts that made her eyes water. She could taste the salty tang of his pre-cum on her tongue as he used her mouth for his pleasure.
"That's it," Marcus growled above her, his hips snapping forward as he drove himself deeper down her throat. "Take it all like a good little cocksucker."
Sarah could only whimper in response, her nose pressing into his groin as he hit the back of her throat with each brutal thrust. She could feel him getting closer and closer to the edge, his balls tightening against her chin.
But just as she thought he might come down her throat, Marcus pulled out abruptly, leaving her gasping and sputtering on her knees.
"Not yet," he said roughly, hauling her up by the hair and shoving her face down on the couch once more. "I want to come inside your tight little cunt first."
Sarah barely had time to process his words before he was behind her again, the head of his cock pressing insistently at her entrance.
"Beg for it," he commanded, rubbing himself up and down her slick folds but not entering her fully. "Beg me to split you open on my big black dick."
"Please," Sarah whimpered, pushing back against him desperately. "Please fuck me. Please fill me up with your huge cock. I need it so bad."
With a savage grin, Marcus pushed forward, burying himself to the hilt in Sarah's tight heat with one brutal stroke.
Sarah screamed in ecstasy as he started to move, pounding into her with deep, powerful thrusts that rocked her entire body. She could feel every thick inch of him sawing in and out of her most intimate depths, stretching her beyond what she thought possible.
"Yes," she cried out, bracing herself on the arm of the couch as Marcus fucked her with abandon. "Fuck me just like that. Fuck me hard and deep and don't stop."
Marcus grunted in response, gripping her hips with bruising force as he drove into her again and again. The obscene sound of skin slapping against skin filled the room, mingling with their moans and grunts and the slick, squelching noises of Marcus's cock plunging into Sarah's sopping pussy.
Sarah could feel another orgasm building at the base of her spine, centered in the burning heat of Marcus's cock splitting her open. It swelled and grew, pushing her closer and closer to the edge until finally it exploded through her with the force of a nuclear bomb.
She screamed until she was hoarse as she came harder than she ever had in her life, her cunt gushing and her ass clenching rhythmically around Marcus's pistoning shaft. He followed a split second later, burying himself balls-deep in Sarah's spasming hole and flooding her with what felt like gallons of hot cum.
They collapsed together in a sweaty heap on the couch, chests heaving as they struggled to catch their breath. Sarah could feel Marcus's cum leaking out of her ravaged pussy as they lay there, marking her as thoroughly owned and used.
Finally, after what felt like hours but was probably only minutes, Marcus rolled off of her with a low groan of satisfaction. Sarah lay there for a few moments longer, basking in the afterglow of their incredible coupling before slowly pushing herself up on unsteady arms.
"Thank you," she breathed, turning to face Marcus with a shy smile. "That was...incredible."
Marcus smirked at that, reaching out to tuck a strand of hair behind her ear. "Anytime," he purred. "And remember - I'm always here if you need me. Your husband may be able to provide for your needs twice a week, but I'm available whenever you need a real man."
Sarah felt a thrill at his words, knowing that he was right. Mark could never satisfy her like Marcus could - could never fill her up or stretch her out or make her feel as good as this massive black bull could.
With a final smile, Marcus got to his feet and tucked himself back into his pants. He dropped a casual kiss on the top of Sarah's head before heading for the door.
"I'll see you soon," he promised as he left, leaving Sarah alone in the living room with nothing but the lingering scent of sex and the knowledge that she would never be satisfied with anything less than what Marcus could give her.
