As the evening wore on, Sarah found herself increasingly drawn to the idea of something naughty. She had always been curious about anal sex, but never had the courage to bring it up with her husband. Tonight, however, she could feel the heat building within her as she imagined what it would be like to have his thick cock buried deep inside her tight rear.
She slipped into something short and lace, teasing herself with thoughts of what was to come. Her husband, Mark, was hard at work in the garage, and she took this opportunity to slyly apply some anal lubricant to herself, knowing that it would make things easier for him later.
When Mark finally came inside, exhausted from his workout, Sarah met him at the door with a glass of wine and a sultry smile. She led him to the bedroom, where she'd lit a few candles to create a romantic atmosphere. As they began to undress, she noticed that Mark's eyes kept wandering down to her ample behind.
"Do you like what you see, Mark?" she asked, playing with her hair and giving him a teasing glance over her shoulder.
He couldn't resist any longer. "Sarah... I've always wondered what it would be like to..." he trailed off, hinting at his desire for anal sex.
She smiled and moved closer, rubbing her bare thigh against his crotch. "I think you're going to like it," she whispered, biting her lower lip in anticipation.
Without further ado, she climbed onto the bed on all fours, pushing her ass high into the air invitingly. Mark's cock twitched as he watched his beautiful wife expose herself so wantonly. Slowly, he approached from behind, running his hands over her soft skin until he reached his target - her plump, round ass cheeks.
He spread them wide and pressed his cock against her tight anus, gently pushing against the drenched, slippery entrance. Sarah moaned in pleasure as she felt him teasing her rim, swirling his thick cock around her asshole. Suddenly, she felt him push forward, and with a gasp, his massive girth breached her tight hole.
She cried out in pain and pleasure as he continued to thrust deeper into her ass, stretching her walls. She could feel the unfamiliar sensation of his balls slapping against her wet pussy, and she writhed in ecstasy. Mark was thrusting harder now, pumping his hips as he drove himself deeper into his wife's hot, tight rear.
As she got used to the sensation, Sarah began to meet his thrusts halfway, pushing back against him. The feeling of being filled up completely, of having her asshole stretched to its limits, was overwhelming. She couldn't believe how amazing it felt to have her husband's cock buried so deep inside her.
With each thrust, she felt herself getting closer to the edge. She could hear her own wet sounds echoing in the room as she reached between their bodies to stroke her swollen clit, punishing herself for feeling so good. As she neared her peak, Mark grabbed her hips and started to pound into her ass relentlessly.
Finally, she felt herself about to cum, and as she did, she felt the familiar heat building inside her ass. Mark had begun to cum too, and his hot, thick semen exploded into her bowels. She felt his cock pulsing inside her, filling her up with his sweet love juice.
As they both collapsed onto the bed, exhausted but satisfied, Sarah couldn't help but think that this had been one of the best experiences of her life. She reached back and softly caressed Mark's swollen member, still buried deep within her ass. They laid there together, wrapped in each other's arms, and fell asleep to the sound of their mingling rhythmic breaths and the soft slapping of their newly discovered anal love affair.
