We're in Budapest, for a few days of relaxation. We enjoy the art galleries and museums, and strolling through the old town. We are treating ourselves by staying at the Exelsior, an elegant, centrally located, grand beauty of a hotel.

We've been to Budapest a few times, enjoying the many bars and clubs.

But here we are, at the end of an erotic long weekend of fun, and it's our last night in the hotel bar.

Luxury, cosy, hotel bars are a favorite for Charlotte, and she has dressed for the occasion.

She wears a floating, loose-fitting, knee-length, summer dress, which shows off her long, tanned legs. Unusually for her, she is also wearing a pair of thin, white knickers that fit tightly across her neat bum and stretch into her cunt crack. She tells me that she enjoys the sensation of her knickers rubbing against her pussy lips when she walks.

The opulent bar is soon filling up with elegantly dressed guests, as befits the style of hotel.

We both notice a tall, immaculately groomed, and well-dressed older man enter the room and look around. He fits the splendour of his surroundings perfectly. From his arm hangs a pencil-thin woman. She's much younger, squeezed into a pale, cotton dress, her long blond hair cascading over her bare shoulders.

He gives us a courteous nod as he sits opposite, just a few tables away, and pulls a chair out for his companion.

He sits facing us, his companion with her back to us. It is very obvious he has noticed Charlotte, and he does nothing to hide his frequent gaze in her direction.

Unseen by his companion, he gives Charlotte a barely perceptible, thin smile. Charlotte and I both notice his attention with some amusement. His twinkling eyes and flirtatious behaviour are becoming increasingly obvious to us.

The old man must be at least fifteen, or perhaps even twenty, years older than us. He's in good shape, tall, with greying hair, wearing an expensive wristwatch and a tailored dark suit. He has carefully manicured hands, and on his little finger, he wears a blue stone and gold signet ring. It's old money, for certain. The sort of man I know Charlotte is drawn to.

Charlotte plays along with his attention, crossing her long legs and allowing the thin fabric of her skirt to rise up to her thighs. From time to time, I deliberately look away, appearing distracted. This allows Charlotte to look across the room and catch the man's gaze.

She is enjoying the attention, and I can tell from her body movements, she is encouraging the man's stare.

To one side, and opposite him, sits his companion. The young, skinny, bimbo, with perky tits standing proud and straining the front of her skimpy, flimsy, cotton dress. She has long, tanned, bare, legs. Her dainty feet are slipped into silver high-heel shoes, strapped across at her slim ankles.

Compared to the man, she looks tarty. I can't help thinking, he's a lucky devil.

He oozes charm and elegance. She has a sexy look, in a cheap and brassy way. Good for a quick fondle or a fuck, I think to myself. Little do I know how the evening will unfold.

The man is giving his girl a great deal of physical attention, oblivious to us being so close by. He moves his chair to be alongside her. He touches her thigh, slides his hand over her dress, kisses her neck. With each move, he somehow manages to give a quick glance in our direction. He wants us to see him playing with his girl. As I expected, the attention amuses and arouses Charlotte, who smiles back at the man and raises her eyebrows in mock shock.

The man moves his hand under the girl's thigh, pushing upwards and under her dress. She protests, moving his hand away and giggling. It is becoming obvious she has been drinking too much champagne, and as she wrestles to move away from him, her tarty dress stretches across her bra-lass boobs. Her long hair, tousled, hangs loose over her shoulders.

Charlotte and I are transfixed by the two of them, and we both feel the stirring of sexual arousal.

Charlotte is the first to speak. She smiles and gives me a cheeky grin. "I'm just going for some air, and to find the ladies. Won't be long. Be good, and don't misbehave while I'm gone."

As she gets up, the man's gaze follows her graceful walk from the bar, her tight little ass, and her skimpy dress swirling around her hips.

The man tops up their glasses with the bottle of champagne from the ice-bucket. He hands one to the girl, toasts her, and they both finish their drink in one gulp.

She watches, slightly bleary, as he gets up from his chair, gives me the briefest of glances, and heads off down the corridor, taking the same route Charlotte has just taken.

He is following Charlotte, and he seems to enjoy the fact that I'm aware.

I give it less than a minute, and then follow him. I see him, standing against the wall, in the shadows just outside the ladies' toilet. He has undone the buttons of his tailored jacket and placed a hand on his crotch, rubbing the front of his trousers.

I see him unzip himself, pulling out his long, curved cock and holding it in the palm of his hand. As he rubs it, his prick gets harder and longer, the tip glistening in the dimly lit shadows.

I watch from a safe distance, out of sight, as Charlotte comes out of the ladies'. She walks up to the man, stops and stands right alongside him, and gazes down at his erection.

She smiles. I can just hear her whisper, "I had a feeling you might be here. Excited to see me, you naughty old man. Looks like you're even more excited now than you were when you first saw me."

She places the palm of her hand on his open trouser front, wraps her fingers around his cock, and rubs down the whole length of the swelling sticking out from his crotch.

"Hmm, what do we have here? A nice stiff cock. Not bad for an old man like you. Shall we have some naughty fun? I think that might be what you have been hoping for."

Charlotte pulls his trousers wide open, puts her hand inside, cups his balls and brings them into the open. His long, strong, cock has grown to an impressive curved erection and stands proud from his dark pubic hairs. She nuzzles into his neck, kissing him, licking his flesh, her breasts pressing up against his chest.

I watch as Charlotte wanks him, the two of them in the shadows, his back to the wall. He moves his hand under Charlotte's short dress, pulls up the fabric and, moving her white panties to one side, fondles her bare ass. Helpfully, bending her knees, she parts her legs, allowing his hand up her dress, in between her thighs, and up to her vagina.

She sighs and encourages him as he finds her damp crack and slips a finger past the thin knicker fabric and into the oozing wetness.

My cock starts to harden as I watch my lovely wife being aroused by a stranger.

I feel a hand on my arm. The young bimbo stands next to me, slightly the worse for wear. She nuzzles into me, pushing her thin body onto mine, licking my ear, whispering, "I did wonder where he'd got to. Noticed he had an eye for your wife. He's a bit of a womaniser, not that I mind much. Can't let my old man have all the fun, can I. So here I am, Emmy, just for you. "

She slides her hand down my trouser front, undoes the belt and pulls at the zipper. She feels my stiffening prick.

"That feels nice. I think you're getting ready for Emmy's little fingers to have a play."

I am breathless as she finds my erection and brings it out into the open, folding her slim fingers over it.

"How about you and me get it on, while we watch the old man and your hussy wife? Have a little feel of my young, naked, panty-less pussy. I'm already wet for your fingers to slip in."

She rubs her hand down my erect shaft as I feel under her skirt and slip a finger into the warm folds of her hairless wetness. Her shaved pussy feels slippery and inviting.

She sighs and we turn our gaze towards Charlotte and the man. His cock is standing proudly, with Charlotte's hand wrapped over it. With her other hand she leans down and pulls her flimsy white panties to the ground, and then slips them over her feet. She bends down, picks them up, and wraps the thin cotton material over his bulging erection.

She pouts at him. "There, let's see if my panties make you really stiff. Let's have some of your cum dribbling into them."

She wanks him, the soft, silky, panty material rubbing up and down his sticky shaft.

I whisper to Emmy, "Seems anything goes with your old man. Shall we join in with some fun of our own?"

She breathes heavily, opening her mouth and licking my lips. Her hand opens my trousers wide and slips down inside to my crotch.

She reaches down and pulls out my cock, rubbing it in the open air as it grows stiff and long.

As she parts her legs, I slip my finger into her freshly shaved, naked, wet crack. I finger the lips of her cunt, pushing two fingers into the oozing wetness. She bends her knees and widens her thighs as I quicken my hand movement.

The man climaxes silently, his cum splattering over Charlotte's wedding ring, slipping through her fingers into the palm of her hand, and over the white panties in her grasp.

She wipes her pussy clean with them, kisses the old man on the mouth, and folds the panties into the palm of her hand.

Barely a few feet away, my fingers have brought Emmy's little wet cunt to a climax. It coincides with her rubbing my prick as I ejaculate into her hand.

She reels. " I need a tidy up." She moves away and heads for the ladies', passing Charlotte as she walks towards me.

I clumsily tuck my still stiff cock into my trousers.

Charlotte smiles as she comes alongside me. "Had fun, darling? I think we both have."

She holds her damp, cum-soaked panties up to me, and folds them into my jacket pocket. "Souvenir from Budapest. In memory of us both cumming with strangers."
