After several long minutes, Marcus finally pulled out of her mouth, leaving her gasping and sputtering on her knees. "Enough," he said roughly. "I need that tight little cunt now."
Sarah barely had time to process his words before he was hauling her up by the hair and shoving her face down on the couch once more. She felt him lining himself up with her entrance before thrusting forward with one brutal stroke, burying himself to the hilt in her tight heat.
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.
"Fuck," Mark breathed from his armchair nearby, his hand still working furiously over his own shaft. "That was...intense."
Marcus chuckled darkly, rolling off of Sarah with a low groan of satisfaction. "Your wife is quite the little slut," he agreed. "I'm going to enjoy breaking her in."
Sarah felt a thrill at his words, knowing that he would be back for more - that she would be his to use whenever he saw fit. She knew that Mark would be there to watch and clean up after him, to worship his bull's cock and take what scraps of cum he left behind.
With a final smirk in Mark's direction, Marcus gathered up his clothes and began to dress. "Same time next week?" he asked casually as he headed for the door.
"Same time," Mark confirmed, his voice strained with unspent arousal.
And with that, Marcus was gone, leaving Sarah alone with her husband in the aftermath of their intense encounter.
As they lay there on the couch together, basking in the afterglow of their debauchery, Sarah knew that their lives would never be the same. She had tasted paradise now, experienced pleasure on a level she never even knew existed.
And she knew that she would never be satisfied with anything less than what Marcus could give her - what he and countless other bulls like him could offer her.
Next day, Sarah's phone buzzed with a new text message, jolting her out of her work-induced daze. She glanced down at the screen, her heart leaping into her throat when she saw that it was from Marcus.
"Hey sexy," the message read. "Got a surprise for you tonight. You and me, plus another toy. My place at 9. Don't be late."
Sarah felt a thrill of excitement and nerves as she read the message, her pussy clenching with anticipation. Another toy? The thought of being used by Marcus and some unknown woman sent shivers down her spine.
She quickly typed out a response, keeping her words short and to the point. "I'll be there," she said simply.
As the day wore on, Sarah found it increasingly difficult to focus on anything else. Her mind was consumed with thoughts of the night to come - of the pleasure and degradation that awaited her at Marcus's hands.
When she finally arrived home that evening, she was greeted by Mark's concerned expression. "You're home late," he said, frowning slightly. "Everything okay?"
Sarah forced a smile, trying to play it casual. "Yeah, just got caught up at work," she lied smoothly. "I'm gonna head up and change real quick. I promised a friend I'd swing by for a girls' night, so I probably won't be back till late."
Mark's frown deepened, but he didn't press the issue. "Okay," he said reluctantly. "Have fun. Don't do anything I wouldn't do."
Sarah rolled her eyes at that, knowing full well that there was nothing Mark wouldn't do when it came to her - including sharing her with other men. But she just smiled and headed up to the bedroom, grabbing a quick shower before slipping into a tight little black dress that hugged her curves in all the right places.
She could feel Mark's eyes on her as she came back downstairs, taking in the sight of her. "You look gorgeous," he said softly, reaching out to pull her into a hug. "Have fun tonight. I'll be waiting up for you."
Sarah felt a pang of guilt at his words, knowing that she was lying to him. But she pushed it aside, too excited for the night ahead to dwell on the implications.
"I'll try not to wake you," she promised, pressing a quick kiss to his lips before grabbing her purse and heading out the door.
The drive to Marcus's place was a blur, Sarah's mind racing with anticipation. When she finally arrived, she took a deep breath to steady herself before ringing the doorbell.
Marcus answered a moment later, his eyes darkening with lust as he took in the sight of her. "Damn," he purred. "Looking good enough to eat."
Sarah felt a rush of pride at his words, stepping forward to press herself against his muscular body. "I'm ready for whatever you've got planned," she breathed.
Marcus smirked at that, his hand drifting down to cup her ass. "Oh, you'll get more than you can handle," he promised darkly. "Come on in."
He led her into the living room, where a petite blonde woman was already waiting on the couch. She looked up as they entered, her eyes roving over Sarah with clear interest.
"Dana," Marcus said by way of introduction. "My favorite little toy. She's going to help me break you in tonight."
Sarah felt a thrill at his words, knowing that she was in for a wild ride. "Pleased to meet you," she said, extending a hand.
