Paul had his cock balls deep in my wife. I could see them tighten suddenly and he groaned loudly as he pumped his cum into her pussy, her own answering moan expressing her pleasure as she felt him cum hard inside her.

My cock was locked and straining its cage and my buttocks still red and sore from the spanking Paul had given me in front of my amused, encouraging wife. I watched him demonstrate his ownership of her, filling Emma with his seed, making her cum and passionately cry out for him…

Could it really only be two months since my wife had first cuckolded me? It hardly seemed possible that so much could have changed in so short a time. Especially as it had taken years of hinting, persuasion and encouragement to get her to even consider either seeking a relationship with, or responding positively to another man.

The catalyst had been the summer ball at the local RAF Station. As the resident psychologist, Emma had been invited and was looking forward to the social event. She had wanted me to go with her but I'd said she would probably have more fun on her own. She'd been disappointed but had finally agreed and, slightly miffed, she had followed up on my suggestion that she take a room at the base for the night so that she didn’t have to drive home afterwards. 

As the date of the ball drew closer, I took the opportunity to try and persuade my wife to indulge my other fetish – locking me in chastity! On the whole, she had never been keen on this idea but I told her she should lock me up before she went to the ball so that she knew for sure that I would not be masturbating over her whilst she was away.

I said the thought of her in her stockings and heels and her lovely new dress would undoubtedly have me wanting to play with myself – and that, if she locked my cock away, she could ensure I waited for her return the following day.

For the first time ever, Emma looked genuinely thoughtful about the concept. I didn’t press her, but when she was getting ready on the Saturday evening, I brought the chastity device to show her. She still looked a little dubious, but with a slightly exasperated sigh, she told me to go ahead and show her how it worked.

I took my trousers and pants off and between us we got it fitted. Once the lock snapped into place she stepped back and looked down at me lying on the bed. She pursed her lips and then smiled. Finally, she actually giggled, admitting it was a bit of a turn on seeing me like that, all locked away. 

We had struggled a little bit putting the device on, because Emma was only partially dressed – and her touch had me growing almost instantly. But with a little lubrication and a lot of pushing and shoving we had got it away. When Emma asked what she should do with the two keys I said she should put them on a chain around her neck. She laughed and asked what should she say if someone asked about them?

'Tell them the truth,' I said.

She looked at me strangely but, to my surprise, did as I suggested.

As she fixed the keys in place around her neck she looked at my reflection in the mirror.

‘And if I meet a tall, dark, handsome stranger…?’ She asked, half-teasing, half serious.

I looked back at her unsmiling face in the mirror.

‘You wouldn’t believe how much the thought of that turns me on…’ I whispered.

Emma was silent for a long moment and then gave a long sigh. ‘Don't tempt me,' She said. 'Time to go.’ 

Emma didn’t return until nearly 4 pm the next day. I spent most of that time wondering – especially as Sunday lunchtime came and went and she didn’t come home. Eventually, when she did come home I met her at the door, having heard her car pull into the driveway. She gave me a kiss but was otherwise quiet and wouldn’t meet my eyes. I made her a cup of tea and sat down with her.

‘What’s up?’ I asked.

At that, her eyes brimmed with tears and she started to shake.

‘I’m sorry,’ she said. ‘I’m so sorry.’

‘hey, hey, shush...’ I said ‘Tell me what’s the matter...?’

Slowly, over sobs, her story came out. She’d spent a good deal of the evening with a pilot called Paul. She had had a fair bit to drink and in the early hours, she’d found herself in his quarters, kissing him. She said that she'd thought then of all the conversations I’d had with her about her being with another man, and she said she was never sure how serious I was.

Emma looked at me. 'To be honest, I was also a bit annoyed at you, for not coming to the ball with me. And then, all of a sudden I thought, "Why not? This is what he says he wants! And Paul is an attractive man and clearly wants me!"’

And she said she found herself sliding to her knees and unzipping Paul’s fly...

I was getting seriously turned on listening to her story – I could feel my cock straining uncomfortably at the chastity cage. She told me how she had sucked his cock – something she had not done for me for years! She related with shame how Paul had come in her mouth, and she’d swallowed every drop so as not to make a mess of her hair or dress. Then she said she’d had an attack of conscience and had told Paul she couldn’t stay in his room. He’d been disappointed but she had instead invited him to her room in the guest wing.

Emma looked so crestfallen. I, on the other hand, was so excited I was almost coming in my cage. I couldn’t ask questions fast enough. What had they done?

'He fucked me!' She said straightforwardly, with both wonder and shame in her voice.

She was quite forthright with the word, which she didn’t use often, and it turned me on, even more, to hear her use it. She said she'd been shy and a little reluctant so Paul had taken charge of her – and she had let him. She said he was very manly and that he couldn’t seem to get enough of her.

Emma didn't seem to understand this, but I did – my wife lacked confidence in herself but I knew others found her attractive, even in her late forties! Emma said that the first time she’d knelt on the bed and Paul had simply lifted her dress over her back, pulled her knickers down and fucked her doggy style. She whispered shamefacedly that she'd been so wet that he had slid straight into her.

Had he cum in her?

Yes, at least three times that she remembered. Emma's face burned red as she said this.

Condom?

She didn't think so.

Was she going to see him again?

Emma hesitated. ‘He wants me to...’ Emma burst into tears again. 'Please forgive me!!'

'There's nothing to forgive,' I said. 'You know it was what I wanted you to do..'

'But...'

'No buts!'

Emma looked so vulnerable, she was sitting, playing with a cushion. After a moment she whispered, 'Are you sure...?'

'Did you enjoy it?' I replied. Emma hesitated, then she gave me a crooked smile.

'Yes, I did.' She admitted, a little sheepishly. 'I'm sorry..'

'Don't be! Enjoying it was the whole point!' I hesitated for a moment myself, then asked,'Would you tell me what, in particular, you enjoyed? 

Emma looked at me for a what seemed like a long time.

'Do you really want me to tell you?' She asked, looking both bashful and curious.

I just nodded in reply. Emma was quiet, gathering her thoughts.

'I still don't understand,' she said, 'why you wanted me to do what I did, or, or why it seems to excite you...' She paused. 'He did ask, you know, about the keys I mean.' She looked me in the eye. 'I'd had a few drinks by then and told him exactly what they were. He seemed fascinated.'

She reached out and rubbed my groin, feeling the cage through the material of my jeans. 'Let's have a look then!' She said.

I hurriedly pushed my jeans and boxers down so she could see my cock, locked away for the last twenty-four hours. 

'Are you excited?' she whispered.

I simply nodded, as she stroked around the cage. I couldn't feel her fingers but I was straining out of the sides of the cage, which she could see.

'Paul has a very nice cock,' she said. 'It looks nice, and feels nice and – tastes nice,' she said, raising her eyes to meet mine as she continued stroking. My breathing had accelerated and I could feel my cock pulsing in its cage.

'I enjoyed taking him into my mouth,' she continued, matter of factly. 'Even though he's quite a bit bigger than you.' Emma smiled at me coyly; 'I could feel when he started to cum and I started to panic for a moment – you know I don't like cum in my mouth, but I didn't want him to make a mess – so I just thought “to hell with it!” and kept pumping him with my hand and started swallowing as he filled my mouth.' She paused for a moment and then added, 'I actually quite enjoyed it – the taste of him I mean... and I felt proud of myself for swallowing it all.'

Emma was starting to look like she was enjoying herself, teasing me with her fingers and describing what had happened. Her earlier tears had disappeared and had been replaced by a slightly wicked expression on her face.

'When he took me from behind,' she said looking at me carefully. 'It felt like the most amazing fucking I'd ever had. His cock slid straight into me as I was so wet and he filled me so completely that I couldn't stop gasping. I felt like I was eighteen again, and a total slut – but it felt wonderful! And when he came in me I thought I would burst!'

Emma stroked my balls for a moment and then continued, 'I actually came as I felt him cum in me.' She said, 'That's the first time it's ever happened like that for me. It was almost indescribable...'

Emma looked down at my cock again. 'Would you like me to release you?' she asked.

Again, all I could really do was nod.

'Hmm – I'm not sure I should...' she mused. She looked up at me again; 'After all, you asked for this, didn't you?' She asked, half questioning, half teasing. 'And you've only been in there about twenty-four hours...'

Emma deliberated for a few moments.

'No, I think you need to stay in there for a bit longer,' she said decisively, 'at least until I've worked all this out in my head. Maybe until the next time I've seen Paul,' she added wickedly as she got up and walked away, leaving me in a highly agitated state.
