When they first got together, Mark and Sarah were all over each other as many young couples are.  She was a virgin when they met, in all honesty she told him later, “my plan was to dump you after the first date, you were the biggest guy in the room, and I wanted to get away from someone trying it on”.  She didn’t dump him, and one afternoon they took a walk in the woods near to the swimming pool in the town.  He took her deep into the bushes and found a quiet spot that they would not be disturbed and there they had sex for the first time.  After this they became almost obsessed with each other and within a few weeks of that first date Mark proposed marriage.  It was quick they both knew but love is love and that was that.  Their relationship although loving and passionate was far from conventional.  Mark firmly believed in what some might call a cliché’ “If you love something set it free, if it comes back to you, it is yours, if not – it never was”.

This all happened in the 1980’s now it would be called swinging but then it was ‘wife swapping’ or as they preferred to call it ‘partner swapping’.  But it was more than that, although they often shared adventures with other couples, Mark was a soldier and a DJ so he was away often, many time overnight at weekends or at best he would not return until the early hours.  During some of these times away Sarah would take lovers of her own, a warm body in the night whilst Mark was away.  Mark fully supported these adventures, wishing to himself on occasion that he could watch. Once he returned home a little earlier than expected and had to wait outside in the van while Sarah and her lover finished up.

One Saturday night, Mark was at home and the pair of them had gone to a local dance.  The place was alive and jumping, the pair moved together on the dance floor laughing and joking moving almost in sync as they had for years.  After about an hour or so Sarah seemed to do a double take, she looked through the crowd.

"Jack's here," she whispered, her eyes dancing with mischief.

Mark wasn't surprised; in fact, he might have been more surprised if Jack hadn't shown up. Jack was a part of his regiment and most of them were here.  “I’m going over to say hi” Sarah said, “I won’t be long”.  Marks eye drifted over the room looking to see if there was anyone around, he might have an interest in himself.  Sarah came back a little while later she looked at him slyly, her lips curling into a playful smile. "Can I take Jack home and fuck him?" she asked directly, her voice low enough that only Mark could hear.

Mark's eyes scanned the room and landed on a striking redhead across the dance floor. "I might have my own adventure in mind," he replied with a knowing smile.

Sarah followed his gaze and laughed softly. "Go for it," she encouraged him.

"Alright then," Mark said, leaning in to kiss her cheek. "Take him home. I'll be back later by 11. Be ready for me just in case."

They sealed it with a kiss and Sarah slipped away toward where Jack was standing at the bar, Mark met Jack’s eyes and nodded in an acknowledgement he knew what was going on.  He then walked and danced over toward the redhead, the conversation flowed easily at first, with jokes and laughter filling the spaces between songs. But as the evening progressed, it became clear that his advances would not be reciprocated. She was friendly but firmly uninterested in anything beyond casual conversation.

By 11 PM, Mark was bored and found himself walking home alone, the night air cool against his skin. The rejection didn't bother him much; he knew what awaited him at home.

When he unlocked the front door and stepped inside, the house was quiet. Jack had long gone, but Sarah was waiting. She was sprawled across their sofa, a vision in a tight black Basque that accentuated her curves, matching thong, and sheer stockings that climbed her legs. The dim candle lighting cast shadows that enhanced the dramatic effect of her lingerie against her pale skin.

She rose and propped herself on the elbows as he entered the room “no luck?” she said. “no” he admitted “but my heart wasn’t in it, my mind kept wandering to what you might be up to”.  She pulled him down into a sweet, deep kiss, her tongue slipping between his lips as her hands found the growing bulge in his trousers. His body responded instantly, his hand reaching down to squeeze her breasts through the Basque before letting it travel lower, toward the warmth between her legs.

Sarah unbuttoned his trousers, freeing his hardening cock from its confines. She wrapped her lips around the swelling head as Mark's fingers slipped inside her pussy, finding her clit already sensitive from her earlier encounter. He rubbed gently, feeling her squirm under his touch as she took his cock deeper into her mouth.

Mark gasped in pleasure as he struggled to remove his clothes without his cock leaving her mouth, Sarah raised her hand and grabbed his arse pulling him deeper into her throat.  He slipped his hands down to the back of Sarahs head pushing back gently as he began to fuck her face.

The sensations were overwhelming, and Mark knew he couldn't last much longer. He pulled away and drew Sarah to her feet, spun around and sat on the sofa, gently pulling her down onto his lap. She positioned herself above him, her eyes locked with his as she slowly lowered herself onto his rock-hard cock. She breathed in sharply as he penetrated her, her body still sensitive from her earlier encounter with Jack.

Mark pushed hard upwards, filling her completely, she screamed in shock and pleasure as he grabbed her hips and began to thrust hard and fast, as she bounced on his lap, her breasts eventually spilling out of the Basque with the force of their movements.

Mark reached up and squeezed her tits, covering one nipple with his lips and sucking deeply. The extra sensation drove Sarah wild, thrashing and moaning as she drew closer to her orgasm. With his free hand, Mark cupped her ass, brushing a finger over her anus. He felt her tighten on his cock as her body exploded with climax, her final rush pushing him over the edge as he started to pump her full of his hot seed.

Both collapsed in a satisfied heap on the sofa, their bodies glistening with sweat, their breathing gradually returning to normal.

Afterwards, as they lay tangled together, that Sarah shared what had happened after Jack had left. "When we finished, I started getting dressed into this," she said, gesturing to her lingerie. "Jack looked at me rather confused, I explained that you'd be home soon and I was getting ready for you." Mark smiled at the image of Jack's possibly jealous expression as he left their home.

Only now, years later, as Mark reflected on that night and many others like it, did he fully appreciate how insatiable Sarah could be in those days – and how fortunate he was to have been the one she always came home to after he had set her free.

Their unconventional arrangement had tested their relationship in ways most couples never experience, they had explored the boundaries of trust and desire, always returning to each other stronger than before.

And dear reader – they are still together over 40 years after these events.

Only the names have been changed to protect the (not so) innocent….
