With The Click of a Lock

Once we were in the privacy of our hotel room Emily started to make out with him. There was no need for the casual flirting anymore. It was clear where this was going. Clothes began to slowly come off and soon my wife was standing half naked, kissing another man, while he explored her body with his hands.

More than anything else the whole situation in those moments just seemed... surreal. Watching her remove her tank top. It had been selected earlier that night after much anxious fretting on Emily's part. She had tried on virtually every piece of clothing in her suitcase before settling on the top for its cleavage enhancing properties. She surmised that he had seemed to admire her breasts during their conversations by the pool over the previous few days. I couldn't deny her logic, and the red bra that she had selected to go underneath it had served to create a tantalizing canyon between her large breasts as it held them up and pushed them together.

This was the bra that I had just watched him remove. Unlike in the movies it did not just flick off and disappear like magic. The four clasps were responsible for a considerable task and he methodically undid them until they were released from their responsibilities. Her large boobs dropped down to hang naturally as she pulled the cups from her breasts and dropped the garment to the ground.

I had a momentary view of her spectacular chest before he wrapped his arms around her from behind, lifting, squeezing, and kneading her boobs. Something which I had done myself countless times over the years.

As they returned to kissing passionately my wife's panties were soon drawn down her legs until she was stood entirely nude in front of him. His tie was gone, shirt unbuttoned, and her hands had been exploring eagerly around the outside of his pants. Things appeared ready to progress further.

However, she broke from him and turned to me. She said nothing to him but held up a finger, silently asking him to wait and be patient for a moment. As she crossed the room slowly her eyes fixed on me and she gave me a knowing look.

I had been unsure that she would even go down this path. Just the sheer intensity of the evening so far had caused me to assume that perhaps she would skip this part of the encounter. It was her first time after all...

However, as she crossed the room towards me the look on her face made it very clear what she wanted me to do... and I wouldn't argue.

I walked over to my travel bag and reached for a small case in one of the inside pockets. I opened it and retrieved the contents. Running my hand over it I marvelled at the fact that this was ACTUALLY happening. Returning to my wife I passed the small plastic cage and lock into her outstretched hand. From across the room he watched in surprised curiosity. I reached down and unbuttoned my pants and allowed them to drop to the ground. I slid my underwear down to follow them. Watching my wife being stripped naked in front of me had caused my penis to begin to swell under my clothing. The sudden rush of cool air and the fact that he was watching me get naked served to undermine that and I felt it quickly decreasing in size. I pulled my shirt over my head in order to get it out of the way and provide unfettered access for my wife.

Emily reached to the bedside table and exchanged the cage for our bottle of lube and dripped some into her hands. I gritted my teeth and began to shrink some more as I felt one of her cold hands reach down, lift up my balls, and begin massaging the lube around them. Her other hand performed a similar task on my now flaccid dick. As she coated my penis in slick lube she held it up and pointed it towards her naked vagina, just a couple of inches away. The tuft of blonde pubic hair which traditionally adorned her mound was gone. It had been shaved off in the bath the prior evening as our fantasies of this happening started to feel more like a potential reality. Our lovemaking over the previous nights since she had met him had been spectacular. Each night became more exciting as we explored the fantasy further... and eventually considered it as an actual possibility. Despite how great our sex had been I knew that my efforts were surely about to be eclipsed by the eroticism of her being fucked by another man.

Emily's right hand left my balls and slowly rubbed it's way down her now bald and smooth pussy. The remaining lube was sexily, and slowly rubbed into it as I watched, entranced. She continued to hold my small penis between her two fingers and then lifted her gaze to catch my eye. "Uh uh" she murmured quietly shaking her head. As she did this she comically wiggled my dick back and forth in front of her entrance. So close! As she teased my penis in its smallest state I marvelled at how it could look quite serious when it was erect, but so... silly... when it was small.

Retrieving the cage Emily unlocked it and took the horseshoe shaped ring in her hand. Smiling slyly as she worked, she lifted my balls high and encircled the base with the ring. One by one she inserted the plastic pegs through base. Once complete she expertly fit the top closure onto it, completing the circle which now wrapped snug and tight around my balls and the base of my cock.

The fidgety work, made more difficult by lubricant and the pressure of someone else observing, did not seem to phase my wife. She completed it cooly and with ease, the result of many nights spent fooling around with it in our bedroom. Her locking my dick into the chastity cage. Fantasizing and roleplaying different scenarios. Ones that usually resembled something quite similar to what was actually transpiring in real life at the moment! I still struggled to compute that it was ACTUALLY happening. Thankfully my role in this required very little performance or activity. My nervousness would have surely shone through. In contrast, my wife was handling herself in a confident and seductive manner which far belied the fact that this was actually HER first time doing something like this as well.

The clinking ice cubes in his glass drew my attention. He had shifted to the bureau and retrieved his drink. He now seemingly understood the unexpected surprise and brief interlude and he leaned casually against the corner, giving Emily her space, but watching with curiosity.

With the ring in place Emily now retrieved the clear plastic tube and rubbed a generous amount of lube around the inside. She took a step back from me so that she could more easily asses her task and then pressed the base of the tube up against my lubed up dick. Even slick and in its smallest state my head was still larger than the entrance. Em and I both watched as she applied some pressure, relying on the sponginess of my head to give way which it soon did. It popped into the tube, smooshing out tightly against the clear plastic. With more pressure and the prodding encouragement of a couple of fingers she had soon shoved the entirety of my penis into the tight restraint. As my head pushed into the larger cavity at the end it began to regain its shape, albeit smaller. It rendered my endowment so that it appeared that I had very little shaft, mostly just my head which was restrained back tightly towards my encircled balls.

With the last couple adjustments complete my wife produced the lock. It was placed carefully through the small ring as I watched. She then took a step forward and her free arm wrapped around my back as she came in close to me. I felt her breath on my neck followed by a soft kiss. Another one close to my ear.

"I love you"

In that moment it sounded different, meant to carry several meanings.

Reassurance that everything would be ok and that the bond of our relationship and marriage was at no risk.

Appreciation that I was letting her do something like this. A fantasy that had been held unfulfilled for quite some time...

Confirmation that this was actually about to happen and in turn warning that I'd better get ready. My role for the rest of the night was to watch helplessly as my wife was bedded by another man. To watch her experience the lust of being pleasured by someone else... and to experience what would surely be the intense sexual and emotional frustration of not being able to stop her, fuck her myself, or even achieve an erection.

With that she clipped the lock shut.

"Go sit over there"

Different tone entirely. None of the previous empathy. A directive. It was happening. I could tell that she was trying to be serious and dominant now.

Watching as she returned to him I recognized that it was something that she clearly already knew. When they were kissing her hands had been active enough around his waistline that she would have had a pretty good idea of what he was working with.

It was not something we had discussed in the lead up to this. How would one even address it in a situation like this? Just four days ago he had been a stranger who she had started chatting with at one of the resort pools. The attraction that had developed over the last few days was what had drawn us to this point. Yes, the three large dildos in her bathroom drawer at home supported the notion that much of our fantasy and roleplay involved another partner who was 'larger' than me. But as she had gotten to know him over the past few days the topic of penis size certainly had not come up! In the dim light of our hotel room I knew that all of this had transpired due to her genuine attraction to him. Even if he'd been modestly endowed she would have still held the same excitement for this encounter.

As Emily drew down his underwear and her suspicions were confirmed her first reaction was to turn to me. Knelt on her knees she surely appreciated the look of surprise on my face as she revealed him to me. I appreciated the transparent look of excitement, anticipation, and blind lust on hers. She continued to look at me as she let her hand wrap around his thick shaft. Her smile was almost triumphant. Her first big cock.

Raising herself back up again she led him towards the bed and signalled for him to lay down. As he rested his head against the pillows Emily climbed up onto the bed and positioned herself leaning over him at waist level. Sitting in the chair I prepared myself for the first act of what would likely be the most erotic show of my life. Realizing that I was about to watch, and almost telepathically sensing my excitement, my wife rose up. With a sly smirk she twisted her body and repositioned herself so that she was now leaning over him... but facing away from me. I groaned inwardly as I realized she wasn't going to let me see. Instead, I was presented with a wondrous view of her bum as she slowly bent over in front of me and lowered her mouth to him.

The unmistakable sounds of oral sex could immediately be heard and I watched him considerately reach down and hold my wife's hair to the side as she sucked his large cock into her mouth. My view was of her ass, upturned and ready. The seductive curvature of her full bum was perfectly framed by the tanlines around the bottom of it. Several days in the sun had delivered a warm glow to much of her skin, but the areas protected by her one piece swimsuit remained a soft pale white. The same creamy color her whole body had been when we left the cold of Colorado close to a week prior.

The difference in skin tone almost served to accentuate the private nature of certain areas of her body. Anyone at the resort was welcome to view her sexy legs, softly sloped shoulders, or substantial cleavage. But the alabaster white of what was underneath her swimsuit was reserved for those who got to see her only in private settings. Tonight she had invited someone aside from me to see her in her most naked and exposed state. Of her 36 years we had been together for 11 of them. It had been at least that long since she had been completely nude in a bedroom with another man.

As Emily bent over him and allowed me to see her extraordinary bum it essentially served as the world's most tantalizing movie trailer. Preventing me from witnessing the opening scenes... but teasing me with what was to come/cum. I knew that in just a short period of time I would likely be witnessing that same view of her bent over, but with another man's penis plowing in and out of her.

To my wife's credit, her efforts to obscure my view achieved what was likely her desired intention. As I sat glued to the chair it was the ultimate tease. I desperately wanted to see her taking his large penis in her mouth but all I could witness was the top of her bobbing head. The lack of visual fulfillment was made that much more powerful by the aural component. The soft sounds of her mouth were periodically accompanied by a soft moan from him or a compliment on her oral skills. When she occasionally took a break her stifled gasps about how big he was served to further stoke my excitement and curiosity. What was especially sexy was she didn't seem to be saying it specifically so that I would hear. I suspected that there would be some of that in the night ahead, but her exclamations in those moments seemed to be made out of pure lascivious excitement about his size and what it was like to work on a penis larger than what she was accustomed to.

From my viewing position several feet away I looked at my penis in frustration. I could already feel it twitching in anticipation. The dark pink skin had fully filled the cage and it pushed upwards against the transparent plastic making my predicament truly clear. Up to that point I had wished desperately to have access to my penis. Being able to touch it while I watched would have been the fulfillment of Emily and my most erotic fantasy nights together. However as I observed it confined in its enclosure I began to realize that she was likely right to do it. Unlocked I would surely struggle to last through their time together. Masturbating to an early orgasm would likely bring on feelings I didn't wish to explore in this moment. By caging my penis she ensured that I would be present throughout the entire encounter.

It was clear that I wasn't the only one with my cage on their mind. Once Emily was satisfied that she had fashioned him with a proper erection she withdrew from him and sat up onto the side of the bed.

"Come here boys"

Her smile towards him was bright and encouraging. The one she gave me seemed to bely a different set of intentions. He gamely rose from the bed and slid over to the side, following her instructions to stand. Sitting in the chair I realized what she intended. We had seen numerous scenes on the internet play out in a similar fashion. It seemed to be almost de rigueur in situations like the one we found ourselves in. It was usually kind of funny and Emily and I had often laughed together at the predicament of the poor husband/boyfriend. Caged or uncaged he inevitably never measured up. My wife's crooked finger and more stern second look made it clear that she was planning to play this out in person. As I rose I realized that I could likely still appreciate the humor of it all, but it certainly felt a whole HELL of a lot different being the subject!

The several steps towards them felt like the longest of my life. Both he and my wife were looking at me as I walked towards them nude. He was a slight bit taller than me and quite fit. We knew from our previous discussions that he was a long distance runner and his body showed it. Not overly muscular, but slim, toned and taught. A light olive skin tone. Fourth generation English, but a Spanish mother. All details we had learned in conversation during the week. I'm in reasonable shape myself, but it was hard to keep that in my mind as I examined his athletic frame. As I took my place standing next to him it was impossible to miss the most obvious difference between our physiques.

Looking downward my small pink penis had been reduced to less than two inches in length and was surrounded by a transparent plastic cage. The key which secured the lock of it now dangled suggestively on a chain in the middle of my wife's cleavage. While I'm sure she would have loved to have a measuring tape with which to define the actual difference in size, my wife was left to visually compare the two.

His was darker than mine and not only much longer, but significantly thicker as well. I would learn later from Em that while the extra inches were nice, it was the girth, added friction, and feeling of being filled up by him that had given her the most pleasure. His penis stretched far out from his body, hard, erect, and slick from my partner's saliva. Without a device to measure (and scared to ask) I figured him for around 9 inches. Even free from my restraint and at my most aroused I would fall just short of the 6 inch mark. The difference in size was abundantly clear.

"Oh love..." Emily sighed dramatically, adopting a tone that I was familiar with from our bedroom role-play sessions. Her hand raised to my dick and she gripped the head of the cage between her fingers. She wiggled it around playfully before looking up at me.

"Look at your little baby dick... what am I supposed to do with this?

"I guess it does look kind of 'cute' in it's cage..."

Despite the fact that I was being chastened for my penis size in front of another man I had to quickly hide a grin from the corners of my mouth as she slipped into character.

"Isn't his penis tiny?" she asked him as she held my caged endowment outward.

"Uhh..." he stammered slightly.

I could immediately tell that he wasn't comfortable saying anything humiliating towards me. I genuinely believed that he quite liked me. We'd spent a significant amount of time in one another's company over the previous few days and I considered him to be a great guy too. So much so that I had willingly gone along with creating a plan for him to have sex with my wife.

He was surely already surprised enough that the evening had transpired this way. He likely wouldn't have expected at any point this afternoon that my wife would be asking him to pass judgement on the size of my dick.

Sensing that he was supposed to play along but still uncomfortable he hedged his bets.

"Uh, I guess it's a bit small?"

"Come on! A bit small??" Emily chastised him as she raised her free hand to his large penis, encircling it and beginning to stroke it up and down next to mine.

She seemingly sensed that he wasn't going to be much help and I smiled inside at the fact that he was stifling Emily's little game.

She returned her attention to me and continued to suggestively stroke his cock in front of me.

"Darling, I'm not sure if you've noticed, but this dick is far bigger than yours" she cooed to me cooly.

"Did you like me giving you head?" she questioned him, again putting him on the spot.

Without the need to comment on anything related to my endowment he responded more easily. "I did"

"... and do you want to fuck me with this?" she again teased, putting him on the spot.

Her long strokes of his shaft slowed as he hesitated in his response. "Uh, ... if your husband is ok with it then yes I would like to very much"

Getting the response she was after Emily returned her attention to me and tugged teasingly on the cage.

"My husband doesn't get to choose. He gets to watch..."

"He gets to watch his wife get fucked by another man"

It was as erotic as anything I had seen or heard... ever.

Done with her penis competition Emily dismissed me to the armchair and dragged him back to bed. She lay on her back and they were soon kissing again. With his hands free to roam and explore her body he did exactly that. Not surprisingly her large breasts received significant attention. He was soon sucking on her tits, squeezing them upwards and tonguing her nipple before sucking the entirety of her large pink areola deep into his mouth. Knowing how fond she is of boob play I instinctively knew that she would be loving it.
