Mark and Sarah sat across from each other at the kitchen table, a comfortable silence settling between them as they ate their breakfast. The morning sun streamed in through the windows, casting a warm glow over the room.
"I was thinking," Mark said suddenly, setting down his fork. "Tonight is one of our scheduled nights with Marcus. Are you looking forward to it?"
Sarah felt a flutter of excitement in her stomach at the mention of their bull, but she kept her expression neutral. "I am," she admitted. "It's always such a thrill to be with him."
Mark nodded, a hint of jealousy flickering in his eyes. "I know what you mean. He's so...powerful. Dominant. Everything I could never be."
Sarah reached across the table to take Mark's hand, giving it a squeeze. "You're plenty for me, honey," she assured him. "Marcus just...fills a different need. One that you can't satisfy."
Mark sighed, but he didn't pull away from her touch. "I know. And I'm grateful to him for that. For giving you something I can't."
They lapsed into silence again, each lost in their own thoughts. Sarah's mind wandered to the secret sessions she had been having with Marcus behind Mark's back, the way he had fucked her so thoroughly just yesterday. She felt a pang of guilt, knowing that she was keeping this from her husband.
But the pleasure of those trysts was too great to resist. The way Marcus used her body, dominated her and claimed her as his own - it was addictive in a way that she couldn't explain.
As if reading her thoughts, Mark spoke up again. "You've been acting differently lately," he observed. "More...distracted. Is everything okay with you?"
Sarah froze, her heart leaping into her throat. She forced herself to maintain eye contact with Mark, her expression carefully neutral. "Everything's fine," she said smoothly. "Just been busy with work, is all."
Mark studied her for a long moment before nodding slowly. "Okay," he said. "If you say so. But you know you can talk to me about anything, right? I'm here for you."
Sarah felt a rush of love and gratitude for her husband in that moment. She knew that he would support her no matter what, even if it meant sharing her with another man.
"I know," she said softly. "And I love you for it."
With that, they finished their breakfast and went about their day as usual. Sarah tidied up the house while Mark ran some errands, her mind constantly drifting to the night to come.
She couldn't wait to see Marcus again, to feel his massive cock stretching her and filling her and using her for his pleasure. She knew that Mark would be watching, jerking off as he watched another man claim his wife, and the thought only added to her excitement.
When evening finally arrived, Sarah took extra care with her appearance. She shaved every inch of her body smooth and lotioned herself up until her skin was glowing. Then she slipped into a tiny pair of lace panties and a sheer negligee that left little to the imagination.
Mark whistled appreciatively when she emerged from the bedroom, his eyes roving over her scantily clad form. "Wow," he breathed. "You look incredible."
Sarah blushed under his gaze, feeling powerful and sexy. "Thank you," she purred. "I wanted to look good for Marcus."
Mark's expression darkened at the mention of their bull, but he didn't say anything. Instead, he led Sarah over to the couch and gestured for her to sit.
"You know what to do," he said gruffly, settling himself in an armchair nearby.
Sarah nodded, her pussy already damp with anticipation. She positioned herself on the couch, spreading her legs wide and hitching the hem of her negligee up around her waist.
"Fuck, look at that," Mark groaned, his hand drifting down to palm his growing erection through his pants. "So wet and ready for another man's cock."
Sarah moaned shamelessly, rolling her hips in a circle. "Yes," she whimpered. "I need it so bad. I need Marcus to fill me up and use me like the dirty little slut I am."
As if summoned by her words, the doorbell rang at that moment. Sarah barely had time to process it before Mark was up and moving towards the door, his gait stiff with arousal.
He returned a moment later with Marcus in tow, the massive black bull looking every inch the dominant male. His eyes zeroed in on Sarah's spread legs immediately, darkening with lust as he took in the sight of her dripping cunt.
"Looks like someone's eager for some dick," he purred, starting to unbuckle his belt.
Sarah could only whimper in response, too far gone in her desire to form coherent words. She watched with hooded eyes as Marcus stripped off his clothes, revealing his muscular body and massive cock in all its glory.
"On your knees," he commanded, fisting his shaft and giving it a few slow pumps.
Sarah scrambled off the couch without hesitation, crawling towards him on shaky limbs. She looked up at him with pleading eyes as she reached his cock, parting her lips in silent invitation.
"Suck it," Marcus growled, tangling his fingers in her hair and guiding her head forward.
Sarah moaned around his thickness as he pushed into her mouth, 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," he praised, his hips snapping forward as he drove himself deeper down her throat. "Take it all like a good little cocksucker."
Sarah could hear Mark whimpering from the sidelines, the sound spurring her on. She relaxed her jaw and took Marcus as deep as she could, reveling in the way he dominated her.
