Jack and I checked in later than we had planned to our luxury Berlin hotel, the Adlon. To make up time, we agreed to start our sightseeing with a visit to the Neues Museum, just a fifteen minute walk away. To spice things up, as I am always prone to, I chose to dress appropriately for a bit of an adventure.

The weather was chilly so I wore my ankle length quilted blue coat which buttoned down the middle, a pair of long, fur lined leather boots, a chunky pale blue long sleeved knitted polo neck sweater and that's all. No skirt, no knickers. My bare pussy under the long coat. I'd taken the time that morning to shave all my pubic hair so my pussy gleamed neat and tidy, just as Jack likes it.

I did not tell Jack I was not wearing panties when we walked out of the hotel. It would be something for him to discover.

We entered the museum and up the elegant, wide stairwell into the first of many display rooms. It was late afternoon and the place was almost empty, just a few straggling tourists and an attendant on each floor. We walked slowly around the various exhibits and through several rooms. All the while I was casually gazing up at the ceiling checking for CCTV cameras. I was planning my next move and when to pick my moment. All round us on several floors and in many rooms were various display cabinets, pillars and columns with balustrades and staircases - plenty of nooks and crannies I thought which would suit my naughty plan.

After half an hour of gentle ambling I chose my spot. Between a pillar and a showcase, away from obvious gaze, well lit but relatively private was where I'd begin our fun.

'Oh look at this, Jack. What a surprise to see this here.'

I called Jack over to where I was standing. He looked puzzled as I took his elbow and guided him into the spot I had found.

'See something interesting?' I pulled my coat open to reveal my nude pussy and bare ass. He grinned broadly.

'I should have known darling. Never miss an opportunity to shock do you? Well let's get this holiday off to a fun start.'

He pushed me deeper into the space, let his hands drop onto my thighs and then pushed gently to open my legs apart. I flexed for him, leaning back slightly, opening my pussy wider and at the same time undoing his trouser belt. His cock was already hard in my hands.

'Here, do you think?' He asked, looking anxiously around him.

There was nobody we could see but we knew the attendant would not be far away. So we had to be quick whatever we chose to do.

With me standing, braced up against a display cabinet, he slipped his cock into my wet pussy crack with ease. I was so damp with anticipation droplets of cum oozed around his cock. I drew my coat around us both, hiding my body from public display. I was all Jack's. He began his slow strokes into my shaved pussy and it felt so good and so terribly naughty. Sex in a forbidden place has always turned me on.

Suddenly we got spooked hearing footsteps close by and he pulled out his cock so fast I barely had time to adjust my coat.

The attendant walked past a few feet away not even giving us a second glance. We stared at one another. We weren't finished quite yet. My pussy was oozing still and Jack's cock was so obviously hard and bulging in his trousers.

We climbed to the next level. It was even quieter here but very brightly lit so finding a discrete spot was challenging. My eyes were still scanning for cameras, Jack seemingly so aroused he was close to masturbating himself to orgasm.

Behind a large panel which had been placed temporarily to screen a display we found our place.

'Put your coat on the floor,' said Jack as he pulled it from my shoulders.

'Lie down.'

I did as I was asked. My body long and slender, lit by gentle shadows, my legs stretched out, my pussy still wet and waiting, my breath panting, Jack dropped his trousers and released his throbbing erect cock, still oozing semen from its tip.

"Be quick," I pleaded.

He dropped to his knees, bent down and sank his stiff prick into me and my juices, fast and furious. I clenched his shoulders urging him on with soft whispers. Not enough he must have thought and turned me over onto my front so I was now on all fours. He entered me from behind, doggy style, with strong thrusts, pushing in between my wet shaven pussy lips, stretching them wide, my cum dripping onto the lining of my coat, sliding in and out with long, hard thrusts until he exploded with a spasm of hot semen which splashed onto my ass as my orgasm rippled through me.

I turned over to face him, pulling my coat back over my shoulders while my pussy oozed with his warm cum.

"What a clever boy. Very nice. And very naughty also."

We adjusted our dress, used a tissue to wipe the cum stains, hugged and kissed, locked arms and walked calmly out of the museum hall, passed the friendly attendant who gave us a farewell wave and the remaining tourists and out through the front entrance.

We reached the Adlon Hotel early evening.

"I have an idea," I said as the lift took us to our floor.

"Oh really?" Smiled Jack. "Another one on the same day?"

"The Spa and Sauna does not close till nine in the evening. How about we get a drink in our room, get ready and wander down there. It's sure to be empty this time of day and we could have the whole place to ourselves?"

We wolfed down a couple of large Gin and Tonics from our mini bar. it was almost seven thirty by the time we walked into the luxurious Spa and Pool area. It was empty. Just one attendant nearby, clearly close to coming off duty.

We had the beautiful, long pool to ourselves and swam along the edge. I don't know why but I thought to myself, this will help clear Jack's semen from my pussy. My dirty thoughts clearly not all spent yet. We grabbed some towels and a drink and settled in the lounge area choosing a corner chair so as to be mostly invisible from preying eyes.

I saw Jack's penis hanging onto his leg, just under his towel and could not resist bending forwards to give it a kiss.

"That's for later," I teased.

"Have you read the proper sauna dress code?" he asked with a grin.

"It specifies no clothing as one of the rules."

As we were toying with the idea of a quick naughty fumble on the chair, we heard the noise of people entering the Spa. A group of several animated and excited German men and women all jumped into the hot tub which was near us.

We thought it best to escape the noise to the quiet of the Finnish Sauna. Taking off our bathing costumes and placing them in a locker, we wrapped clean white towels around our bodies as specified in the hotel sauna rules and entered the wooden lined cubicle.

The hot stove pushed out steam and soon our bodies were glistening. I opened my towel and let my fingers spread the lips of my shaven pussy, with my other hand I went to slide under Jack's bottom to explore his cock and balls, hopefully as a prelude to a quick fuck between us. A fuck in the sauna, so close to strangers, was a real turn on for me.

Then the sauna door suddenly opened. In came three couples. All German. Excited, slightly inebriated, laughing, towels barely concealing their private parts. Two of the couples were mid forties. The third couple, wealthy looking, fit and slim must have been around our age, early fifties.

"Guten tag," said the older man and grinned at us.

"Hello," smiled Jack, feeling just a little uncomfortable and trying to control what a moment ago was a swelling penis.

"Ah, English," said the man as they all took a seat in the sauna, packed around us.

"Nice to have you here with us. You like German sauna?"

We nodded. Secretly we wished we could have left.

"And you know the rules, right?" He grinned.

"No clothes."

With that he pulled his towel away revealing a muscular, tanned torso and, as we both noticed, a large and pendulous cock. Somewhat larger than Jack's, I could not help observe. He spoke something in German to his wife and she too pulled off her towel revealing a well defined and trim body with perfect breasts, long elegant legs and a shaved pussy which she happily allowed to open up for us by spreading her legs a little wider than necessary. I had to admit she was a pretty woman and as I glanced at her pussy it reminded me of my own. Slim and neat. I allowed myself to imagine her being fucked by her large husband. The two of them curled together, her pussy filled with his throbbing penis, their juices mingling. I stopped myself or else I'd start to feel horny again.

The man grinned. He spoke again in German to the other two couples.

As a team, each threw aside their towels letting them drop to the ground. We were now staring at a row of nude folk all smiling at us. I have to say all the bodies were not bad. The younger couples had looked after themselves also and each one of them seemed completely at ease with being naked. One wife even pointed to her man's cock and nodded, as if to say she approved. Another took her partner's penis into her hands and blew a kiss at it. They all laughed.

Nudity, even in a group, was a natural state for these Germans. The atmosphere was relaxed and friendly. They admired each other's bodies, fondled their parts even but there was no malice, no crudeness, no seediness. Just fun.

The older man turned his attention towards me. I should have expected this. With an inclination of his head and a puzzled look he pointed to my towel. I knew what he wanted.

All his friends looked on and smiled between themselves, nodding encouragement. What was there to loose I thought. I'm not ashamed.

I unwrapped the towel from around my body. sat straight, naked legs together, arms to one side and smiled. The man nodded. Jack did the same, pulling his towel from his lap, conscious of the gaze from the three women fixed on his cock.

They all began to chatter excitedly. The older couple put their arms around each other, still looking at Jack and me.

"You like fun too?" He asked.

"Together. Like us," he winked.

With that his hand opened his wife's legs apart and he jabbed a fat and long finger into her bare pussy. She threw her head back, sighed and wriggled onto his finger. The juices began to flow as he pushed in harder and with a circular motion, her legs now wide apart for all to see. The smile on her face said it all. More please. More.

Her husband's cock started to grow and he pointed to us. I got the hint even if Jack was slow on the uptake. They wanted us to play with one another in front of them.

I obliged, leaning over and massaging Jack's cock, feeling myself between my opening legs. feeling myself getting wetter.

The other couples looked on in various states of arousal. Some masturbating themselves, others playing with their partners, all with wide grins on their faces.

The old man was still fingering his wife's wet pussy as he moved towards me, his other hand at the ready. I pushed myself forwards and away from Jack who now had his prick in his hands, my naked pussy wet with desire, dripping cum, wanting more. The man slipped in two experienced fingers and they gently caressed my open slit. His wife gazed down at me, her pussy so like mine, both of us dripping cum down our thighs, his fingers wet with both our juices.

I took his prick in one hand, Jack's in the other. They both felt very different. Little and large. But equally hard. The four of us were now in a ring of hot and frenzied erotic passion. Jack allowed his hands to wander along the older woman's thigh and into her crotch taking over from her husband's fingering with his own. I strained to get the two men to cum, rubbing the swollen cocks up and down, lubricated by sweat and semen. And below me my pussy was overflowing with my own cum juices as fingers probed deeper and with more rhythm.

We synchronized orgasm. All together, all to the delight of the other two couples who came in turn, one after the other.

I looked around. We were hot, spent, covered in semen, happy, contented, electrified and exhausted.

I wanted no more. It had been a busy day. I leant down to kiss the old man on the lips. Then I kissed his wife the same way and for a fleeting moment she put her tongue in between my lips and into my mouth. I hesitated and then let her, the two of us licking each other's mouths, feeling our wandering tongues, exchanging saliva as our husbands watched it run down our chins. She was a good kisser and I reciprocated wildly, enjoying sharing sloppy lesbian action, wet tongues and lips. I felt erotic, naughty, abandoned, carefree. Another memory for us both I thought.

"Tomorrow." The man nodded his head at us both.

"We are here," his wife added.

I smiled and wondered. Could we do it again?

We'll certainly be back to this hotel and this spa sometime soon. But I wonder if these lovely, exciting and adventurous people will be also.
