Within a few minutes, Heike and Martin were lost in an ocean of memories, albeit from different perspectives.

Martin's decades of travel had seen food nostalgia resurface regularly, and on this particular day, Germany was the host.

Heike had seen the stranger take a serving of fresh sauerkraut from the assistant, and Martin had quickly returned the smile that it had brought to Heike's face. After that, a conversation about the history behind Martin's fondness for the dish began.

Though Heike had met many natives who had visited Germany since moving to London, far fewer had spent time in the eastern part of the country, or in the eastern part of Berlin, before reunification. Heike wasn't someone who viewed the past with regret, but she was curious about how a young Westerner had found visiting her birthplace at a time when it would have been very different from his own.

"Handing over my twenty-five Mark in exchange for the same number of Ostmark and having until midnight to spend them was a challenge every time I went. I made five or six attempts, but often ended up 'accidentally' leaving some of my allowance on the table at the last bar," Martin explained.

Though she had lived and worked as an interpreter in London for over twenty years, Heike was still interested in hearing Martin's accounts of the people he'd met and the more unnerving moments from trips that were still considered quite adventurous.

"The mirrors on sticks used by border security on trains to check for stowaways will always stay with me. I recall a fellow tourist looking panic-stricken when she saw one, and how she had confided that she had run out of knickers and wasn't wearing any under her skirt once the security check was over." Martin explained.

"It's just as well those searches are in the past, or I'd be in big trouble right now," Heike said, hitching her skirt as she sat on the bench she shared with Martin to confirm that her dress code matched the passenger's.

Once Heike had dropped her erotic bombshell, she advised Martin that adjourning to her flat to continue their conversation might be the safest option.

"We need to go somewhere a little more discreet, if that sounds agreeable," Heike whispered with a mischievous giggle.

Though shell-shocked, Martin found that Heike's cryptic reassurance eased his worries. It wasn't the kind of adventure he usually sought, but Heike made accompanying her home sound the most normal thing imaginable.

"We chat, we laugh. After that, who knows? But I may need to conduct a thorough search before I allow you to cross the border," Heike explained.

As soon as they reached her flat, Heike led Martin inside, explaining that he was the guard and needed to search her thoroughly before she could continue her journey.

"People will try anything to beat the system, so you need to think about where I might have hidden any contraband and do your civic duty," Heike said amid laughter and mounting excitement.

"I've had a tip-off from an informant. She's told me exactly where to look. It's dark and very wet down there, so we'll start with a fingertip search. If we're still suspicious, we can change our equipment," Heike continued, struggling to contain her giggles of anticipation.

"Well, that's the chat and laughter boxes ticked," Martin said, as Heike tore off her clothes, jumped onto her bed, and dragged her guest with her so he could plunge his fingers into her pulsating wetness.

"Quickly and deeply, we need to capture all the evidence," Heike smiled, incorporating her needs into the scene.

Martin responded exactly as Heike needed, and her trademark high-pitched giggles of arousal soon filled the room. Heike followed her laughter by thrusting against Martin's pumping fingers, a move that surprised even her.

"If you stick your thumb just there, you might flush out any particularly sneaky hideaways," Heike suggested, easing her attention away from her clit so Martin could include it in his detective work.

When Martin introduced his thumb into her chasm of chaos, Heike felt a surge of erotic adrenaline spin through her body. The comic scenario added so much to her arousal that she felt it was highly appropriate to include it in her next request.

"Send suction in. We need to deal with the rising waters, or the stowaways might swim into depths I've never reached!" Heike shouted urgently.

Martin needed no further guidance after hearing about the updated plan, so he eased into position and slid his tongue into Heike. Flicks, swirls, and plunges made Heike wriggle and giggle with anticipation, and Martin let it build before planting deep kisses exactly where she wanted them.

"Full power. We need to act fast," Heike shrieked as her arousal intensified.

Martin responded to Heike's request immediately, and his intense kisses held inside her. Heike's reaction was a blend of a gasp, a cry of excitement, and howls of laughter, all of which combined perfectly.

As Heike writhed, Martin planted his longest, deepest kiss to the sound of Heike welcoming the explosive onset of her climax. The noise was music to Martin's ears, sharpening his focus as each movement sent fresh waves of release through Heike's body.

Heike realised that being a stranger meant Martin would know less about her than those she had been acquainted with for far longer. To her, that was a bonus, not a hindrance, and it made her feel free to express her arousal loudly and unrestrainedly.

Martin's enthusiastic attention enhanced Heike's enjoyment of the endless erotic waves crashing within. Her expectations weren't just being met; they were being dispatched to oblivion, and she had no doubt the unusual circumstances had played a significant role.

As Heike revelled in the unexpected power of her climax, her focus was not as single-minded as she had expected. Her mind may have been on enjoying everything, but her disjointed thoughts also included ideas about how she and Martin might further their adventure.

Every shudder, pulse, and sensation was uniquely special to Heike, and Martin felt the same. Even amid her own excitement, Heike knew her joy would be complete if she could please Martin as he had delighted her.

Martin was eager for Heike to get the full value from her climax, and he made sure the opportunity didn't go to waste. Heike's descent from her erotic high kept her smiling, and her expression stayed that way until she decided to speak her mind about how she felt.

"I think a short break is in order, but our task isn't complete yet. The Chief wants to search the border guard to make sure he isn't a double agent. She needs to be certain the guard hasn't taken a bribe or is hiding contraband. The Chief? That's me, of course," Heike said in her most convincing, authoritative tone.

Heike wasn't sure whether Martin understood the nature of the 'search' she'd planned, though she felt reasonably confident he'd agree to it. For his part, Martin had a few ideas, but he was certain he'd enjoy it all, even if he'd guessed wrong.

During the interval Heike had suggested, she found herself recalling a story she thought Martin might appreciate. It concerned the summers she spent at the coast between her studies.

"We were a group of friends, all twenty or twenty-one. The girls used to get plenty of attention from the Swedish ferry crew. The foreigners seemed exotic, especially to those of us whose studies were our first taste of life beyond smaller industrial towns. One of the ship's crew members who flashed me a smile gave me a sex toy as a present and said I had to practice with it until we could enjoy using it together. I certainly followed his instructions. I'm surprised it didn't catch fire from the hammering it took, and even though he decided another girl was for him, his gift helped me through many evenings that would have left me disappointed by the locals' quality," Heike explained.

After listening to Heike's story, Martin said what he had heard was the perfect way to unwind during the pause in their investigative work. Heike was delighted that Martin felt this way, though her body was already telling her it was time to return to the outstanding task of securing the border.

"My raging arousal won't thank me for this, but I have one more story, if that's OK? If I don't tell it now, its moment of relevance will have passed, and it will wither and die," Heike said, her smile belying the seriousness of her words.

"I can't have a story's death on my conscience. Do tell all," Martin said, returning Heike's smile.

Heike's account described an experience that occurred a few months after her holiday episode on the coast.

"I went to visit someone in the town he had always lived in before moving away to study. It was a small, old town called Wernigerode. Have you heard of it?" Heike asked.

Heike saw Martin nod, and his explanation reminded her that life could always surprise her.

"My friend's favourite beer is Hasseroeder, and the brewery in Wernigerode is better known to many than the town's medieval background," Martin said, laughing.

"You have Ossi mates? I'm impressed!" Heike said, using the pet name people from Eastern Germany often use for themselves.

Although far from crucial to her ability to tell her tale, Heike felt Martin's knowledge of the town's existence and industry added an extra something.

"So, I'm in Wernigerode. I quite liked the guy I'd gone to meet, and I didn't mind travelling to his hometown to see if he was good enough to be my new boyfriend. We'd met in student bars before, but he said he always found it easier to be himself at home.

We spent a lovely day together, and in the evening we walked to an empty apartment he'd rented. We talked about sex and what we enjoyed. I was very honest. When he spoke, he said he couldn't enjoy sex properly unless it began with a blowjob. Hearing this made me furious. I screamed at him, telling him that if that's what he wanted, he should at least be honest about it instead of making up some ridiculous story to make sure he got what turned him on the most. Even though I'd never sucked a cock, and what happened means I still haven't, I felt more let down by his selfishness than by a missed opportunity to tick a box." Heike said, having found telling her story of disaster far easier than she had expected.

Martin's encounter with Heike had been memorable, and hearing what she'd said made him hope she wouldn't jeopardise her enjoyment by taking risks. He wanted to reassure her, but Heike anticipated that Martin would voice his concerns.

"Don't worry, I've done all the thinking I need to on this one," Heike said, confirming her eagerness to resume searching for stowaways and contraband.

Heike felt relieved after sharing her latest memory with Martin. Many would have dismissed it lightly, but that wasn't her way. Telling her story to someone she was sure would be kind and patient meant a great deal to her.

Once Heike had finished speaking, the smile on Martin's face was all she needed to see.

"I'm back in erotic need mode again. Please tell me how you feel about the Chief. That will help me get into the right frame of mind to search thoroughly," Heike giggled.

"I know that to become the Chief, she must have been very determined and shown great commitment to ensuring everything is to her satisfaction before she closes an investigation. I'm sure she's notorious for her thorough methods and dedication, and for always getting the job done," Martin laughed.

"Very smart assessment. You'll go far," Heike said with a grin, positioning Martin on the bed and kneeling between his legs.

"Uniform sex box ticked, but no uniform in sight. That would leave a few people scratching their heads," Martin said with a hearty laugh.

Martin's response heightened Heike's enthusiasm for her forthcoming episode and was enhanced by the episode's imaginative premise. Heike's eyes met Martin's with a smile, and as she giggled with excited anticipation, she took hold of Martin's cock.

"Spill the beans. We share everything," Heike whispered, preparing to ease Martin's erect hardness between her lips, her voice laced with triumph.

Heike wasn't concerned about how long it took or how many times she felt she might want to check for stowaways, but that was because Martin wasn't either. Heike was confident she would soon feel the pleasure she sought, and equally sure it would ignite her body. She knew.

As soon as she began to draw on Martin's arousal, Heike's excitement escalated wildly. Martin's sighs and groans were all the encouragement she needed, and her mind was alive with happy thoughts, free of negativity or regret.

Martin's sounds of delight grew louder with each movement Heike made with her lips and tongue. His noises might have been those of an enthusiastic beginner, but they were honest and genuine. This mattered more than anything to the woman who was provoking them with eagerness and determination.

Martin's twitching and trembling sent Heike's anticipation into overdrive, and she could feel her body hurtling toward climax as Martin neared release. When Martin's cock shot a river of cum onto her tongue, this pushed Heike over the edge, and the pair groaned and shrieked with pleasure.

Heike was overjoyed to discover that Martin's orgasm had heightened her desire to tease out more of the same. Her mind and body were in a state of delightfully confused chaos, and having got Martin to 'spill the beans,' she wasn't going to let him rest until she could see her reflection in the base of the can they'd been stored in.

Smearing her erotic flow over Martin's cock with the tips of her fingers, Heike's 'masterstroke' produced immediate, visible, and successful results. Heike's second sitting was as eagerly devoured as her first, and another shot of Martin's flow onto her tongue sent surges of powerful climax through her body.

"The chief needs to be fully satisfied that you're one of the good guys before you're released," Heike stuttered, rubbing her clit as she applied more of her homemade magic potion to Martin's cock.

"Upsetting the chief doesn't seem like a good plan at all," Martin gasped as Heike's fingerwork left her eager for a third taste and for further progress with 'operation catch-up.'

Heike was keenly aware of the need to balance her desire for pleasure with Martin's welfare. The freedom to do whatever she liked for as long as she felt like it hadn't made her selfish, and her continued delight was possible only if she believed the enjoyment would be shared equally. This was confirmation that Martin was happy to provide.

"It will come as no surprise to you to learn that I'm more than happy to co-operate until the investigation's concluded," he laughed, feeling that letting people have their own way got an unjustifiably bad press.

Heike knew instinctively that Martin's words were genuine. It seemed perfect to her that trust had blossomed as they played out a scenario of suspicion, however lightheartedly, and she decided there was only one way to celebrate it.

"If we conduct our most thorough searches simultaneously, the Chief might even reward the guard with a promotion to her personal aide. That will ensure other opportunities don't turn his head," Heike said casually.

"No pressure, then," Martin replied.

Heike's expression suggested to Martin that her comment was meant as seriously as anything could be in their unique, nostalgia-filled romp. Hinting that she felt they had a future together gave Heike a sense of freedom she might not otherwise have had, and Martin's disbelief at what he had heard was something she had expected.

"It's a promotion celebration now, not a job interview!" Heike announced excitedly.

Heike's revelation that she saw Martin as a regular part of what lay ahead for her was one she was certain would surprise him. However, she also knew she had more immediate matters to attend to and that everything else could wait.

Positioning themselves top-to-toe, Martin and Heike joked about how a casual conversation had turned their world upside down, too. Spending time chatting while making eye contact with something quite different from smiles took a moment to get used to, though it didn't stop Martin from voicing what he felt was a practical thought.

"If the chief and the guard want to finish their task together, I think the guard should definitely start his forensic duties first!"

"I think the guard needs to begin his shift at once!" Heike said firmly, in agreement.

Though Heike had never suspected otherwise, seeing evidence that Martin was looking forward to his task before her eyes was a bonus. A gentle massage of her wet excitement was just the start she had hoped for, and the first flick and tumble of Martin's tongue made her wriggle and giggle with a smile.

"Preliminaries in progress," Heike summarised.

Heike's delight was enhanced by Martin's willingness to make whatever adjustments to his efforts she suggested. She hoped he'd feel able to do the same once she started working on him, too.

Martin's erotic endeavours built gradually, as Heike saw his pleasure in doing so at close quarters. It wasn't a time for long speeches or analysis, and Heike's call for Martin to 'suck me' needed no further explanation.

Though Heike's excitement had escalated slowly to this point, as soon as Martin's lips began to purse inside her, it intensified quickly. Heike's need to deliver 'the chief's expert input' was now overwhelming.

"At least I'll have less to say now," Heike said, laughing, as she slid Martin's cock between her lips, and a beautiful wave of arousal cartwheeled through her body.

The sensation of Martin pulsating on her tongue drove Heike to urgent action. She felt her heart thumping and beads of perspiration on her hot cheeks as she began to suck. As she did, another kiss Martin held inside her produced a throaty moan of approval that Heike hardly recognised as her own.

Heike's sounds of arousal were matched by Martin's as they shared the joy of their actions on each other. They both had visions of the fantasy they had created, and it was this sense of common purpose that mattered most.

The feeling of Martin's cock twitching as she drew on it triggered Heike's climax. Her explosive release's dramatic entrance coincided perfectly with Martin's latest orgasm, and the sounds of joy that greeted the moment were louder and more expressive than expected.

Although Heike's body was gripped by erotic mayhem, her desire to work tirelessly on Martin's cock remained undiminished. Expert craftsmen and women might have had plenty to say about the flaws in technique on display, but neither Heike nor Martin cared as they kissed and sucked wildly on each other.

Sharing the story of her past gave everything a special quality for Heike. Martin felt the same way, making it an experience they knew they would treasure. It also ensured that neither would give up until continuing became impossible, impractical, or too painful.

When the Chief's search was finally declared over, she and the guard left their office and returned to being Heike and Martin. Their creative adventure had ended, but one of even greater magnitude was beginning. It would always carry elements of what had brought them together, though sex on a bed of sauerkraut hasn't happened yet.
