This all started after our daughter Chloe went to university. While she was at home, we were always careful to keep our sex life, as private as possible. We're not prudes, we just didn't think it right to let on about what we were doing. Most parents must think that, don't they? Before she left to go to to university, we talked to her a lot, about having a great time but being careful. Her expression said, I'm not stupid, although she didn't say it out loud.

I wonder if all couples have cycles in their sex lives, where things change, coming, no pun intended and going. Things you do, then don't do, then go back to. Most couples must have loads of sex when they first meet. For most, it must tail off over time. It did for us. In our case, I've no real idea why but it's like we've gone back twenty years. I'm not complaining, actually I'm grateful. When things tailed off, I started masturbating, something I'd not done for years.

It started off, not so innocently. At first I wasn't exactly angry. Disgruntled would probably be the closest I could get. Technology has come a long way since we married. I posed for pictures Stuart wanted, old school Polaroid and 35mm, long since faded and burned in the fire. One evening when we were getting ready for bed, I was sat on the toilet, when Stuart appeared with his phone and snapped a picture. I couldn't exactly get up mid flow to stop him but left him in no doubt about my thoughts. It didn't stop him, as he continued while I showered. I'm not a patch on how I looked twenty years ago but I'm not bad for my age. Never the less, it was something he'd just done. We hadn't talked about it, as we had with our earlier photo sessions.

Like I've mentioned, neither of us are prudes. We watched a bit of porn but never really found it satisfying. The acting is terrible and the sex not realistic. Well, it didn't have much in common with how we have sex. Stuart doesn't have a huge dong, although his knob is pretty wide. I don't have fake boobs or botox. I don't talk much during sex and our orgasms are nothing like what you see on the screen. We also know that there has been an explosion of people like us, and even older couples posting pictures and videos online.

The pictures we'd taken long ago were just for us. Stuart assured me, that he'd never shown them to anyone else. With this resumption, I sought and received the same assurance. With that in mind, I started to play to the camera. The pair of us have always slept naked. Stuart's body heat keeps me warm. Although, he does sometimes complain about my cold feet on his legs. With Chloe away, our nakedness spread to the rest of the house, at least in the evenings and with the curtains closed.

In the old days, Polaroid film was expensive and by the time you factored in developing and printing, not to mention privacy, 35mm wasn't that different. These days, it costs nothing. We already have our phones, the pictures and even videos cost nothing extra. Not just that, you can take as many as you like and storage isn't an issue. The capacity of phones and laptops is massive. We're never going to fill them up. Although, we were giving it a good go. Plenty of pictures of both of us naked but the draw of the moving pictures was too much to resist.

Have you ever watched yourself having sex? It's a strange experience. In your head you have a mental image of what it looks like. On screen it isn't the same at all. Similar but not the same.

I know that my vulva isn't the most photogenic. That doesn't bother me. I know everyone is different, I'm happy with it so why get hung up about it's look. I'd had a mental image of being penetrated but watching video of Stuart's cock going into me was fascinating. Watching my labia moving as he fucked me was almost hypnotic. Watching the movements as I came, after he touched my clit was incredible. Seeing his cum ooze out of me wasn't so great but interesting anyway.

We'd have some of these videos up on the TV in the bedroom, as we got ready for our next session. We were hooked, almost obsessed with videos and photos. Just about every aspect of our private life was being recorded. Seeing his cock throb as he came in my mouth was great. It hadn't occurred to me before but he always kissed me after I sucked him off. I'd assumed that it was to thank me for what I'd done. However, he must have been tasting his own cum. The trigger for this thought, a video of him going down on me after he'd fucked me and cum. In the twenty years or more we'd been together, I'd never considered it before. I probably should have said something but I didn't want to embarrass him. Watching videos of him going down on me were a little disappointing. We couldn't see much. Occasionally, he'd lift his head away and I'd see the tip of his tongue on my clit.

Most of what we did looked pretty good, at least to us. That's not to say that it was all like that. One day doing it doggy on the sofa in the lounge, he slapped my arse. Something we've both seen in porn. All it did was make us both burst out laughing. Concentration broken, you can't really come back from that. A few weeks later, with me face down on the bed, Stuart was going at it hard, in a sort of press up position on top of me, when a muscle in his back went into spasm. We were stuck together like that for over half an hour. My face buried in the duvet and him unable to move but uttering a succession of swear words through gritted teeth. Eventually, his muscle relaxed and we were able to extricate ourselves. Sex can be funny, can't it. One day I got cramp in the back of my leg. I screamed. Stuart took that as a really intense orgasm and started fucking me harder, until I thumped his chest. You can have a laugh about these in hindsight. Although at the time, they aren't funny at all.

That's how things carried on. When Chloe came home during university breaks, we stopped filming. We'd wear pyjamas around the house in the evenings and we tried to be quiet if we had sex. That's something else I'd learned from our videos. Perception is a funny thing. I'd thought that I was grunting and groaning like a farmyard full of animals when we had sex. Actually, I just sigh and whimper. It sounds a lot louder in my head, than what anyone else would hear from me. Actually, in the circumstances, not a bad thing.

It was during the Christmas break in Chloe's second year that things changed. My parents and Stuart's were coming for Christmas. Chloe helped me get the spare room ready, she gave up her room and would sleep on the sofa. It was only for Christmas eve and Christmas day. She didn't mind. You always want to impress your parents. At least I didn't want to disappoint them by ruining Christmas dinner. I pushed the boat out and ordered a goose, rather than turkey, which none of us particularly like. It didn't stop me worrying, about getting everything perfect.

I struggled to get to sleep. Even when I did, I kept waking. I picked up my phone from the bedside table. 3.41am. I decided to go and make a hot milky drink. I almost crept along the landing and down the stairs. My father is a really light sleeper, I didn't want to wake him. At the bottom of the stairs, there was a faint glow, coming from the lounge. Was Chloe awake too? The answer to that was yes. What she was doing chilled me to the bone. She was in her sleeping bag, sat up with our laptop on her knee, the screen lighting her face and the unmistakable sound of Stuart and me fucking, coming quietly from the speakers. I pushed the door open and we just stared at each other. I don't think either us really knew what to say. She didn't stop the video but she was looking at me, rather than the screen. Eventually, I walked in and took the laptop and turned it off. Still not a word exchanged. Chloe broke the silence with something that nearly broke me.

"Can I watch."

"That's what you've been doing, isn't it?"

"Not that. Not the videos, the real thing."

I just stood there, my mouth moving but nothing coming out. How can you respond to something like that. So I didn't. My mind now taken off the need for a milky drink, I now had a lot more to worry about than my cooking skills. I took the laptop and went back to bed. There was absolutely no chance of me getting back to sleep. I didn't tell Stuart what had happened. That would have to come later. Our first priority the perfect Christmas.

I must have looked a bit of a mess. Despite a shower in the morning and the aid if a bit of makeup, my eyes looked sunken. No disguising the tiredness. Chloe on the other hand was bright eyed and bushy tailed. She was brilliant, helping me with everything. Only once did she ask,

"Can I?"

"We'll talk when everyone is gone."

That seemed to placate her. At least for a while. With her help, we turned out a more than presentable Christmas dinned. Gift giving complete, like every time the seven of us are together, we end up playing silly games and drinking. Stuart's mum sips sherry like it is cough medicine. Mine drinks too much and gets all giggly. All very normal apart from the cloud hanging over my head.

It wasn't until our parents had left, on Boxing Day, that I told Stuart what had happened. He didn't look angry but a little perplexed. Chloe just smiled.

"How much have you seen?" He asked.

"Just about all of it. I found it last year. I wanted to login to my Uni account to check my results, when I found the folder. Calling it XXX is pretty dumb."

"That's because it's our laptop, not yours."

"Mine had died and I didn't have the charging lead. So, do I get to watch? I've seen it on video already."

"One thing at a time. Don't you have any concept of privacy?"

"Not really. Nothing at Uni is ever really private. We share virtually everything."

I didn't want to know where that was leading. I don't think either of us have any idea about Chloe's sexuality. As far as we are concerned that's her business. She's never mentioned a boyfriend or girlfriend. Nor has she ever brought anyone home with her. The answer when it came was difficult for either of us to comprehend.

"I like to watch. I caught Estelle with her boyfriend."

"Estelle?" I asked.

"My housemate. I thought they'd freak but they just carried on. So I stayed and watched. Shane's got a big cock and she squeals like a pig when they fuck. He likes me watching and she doesn't mind."

That blew my mind. I'd have died of shame, at anyone catching us. Now I was having those thoughts about Chloe having seen all of our photos and videos.

"Don't you have any boundaries?" Stuart asked.

She thought for a few seconds.

"No. Not really."

"Well, other people do."

"Yeh, granny wasn't impressed but I think granddad wouldn't have minded."

Granny is the way she addresses my mother. When she'd stayed with them, which she did from time to time, she'd edged their bedroom door open, mid.... I hesitate to even think about it or to use the word about my parents. I suppose she thought that in the heat of the moment they wouldn't notice. Afterwards my mother said nothing, as though it had never happened. My father a little more stoic and understanding but suggested that barging in wasn't the way to go.

"I thought we'd brought you up to be better than that." I said

"I know what you've done for me. I really appreciate it but I have to be me, not another version of you. So, in case you were wondering, which I'm sure you were. Yes, I've shared Shane but I prefer to watch. It's just who I am."

I don't think either us knew how to react to that. We'd sent her off to university telling her to have fun, which she clearly was. Our warning to be careful, seemed to have been heeded, except where my parents were concerned. I could well imagine my mother being mortified. I was actually surprised at my father's reaction. Not that I'd ever have been in a situation which required that sort of response. I couldn't actually believe that we were having this conversation with our daughter. Or that she'd witnessed all of our most intimate moments. Including some things I wouldn't admit to doing, let a alone enjoying.

The conversation ended there. She'd said her piece. We'd said ours but nothing had been decided, agreed to or rejected. Our sex life took a plunge off a cliff. What had been three times a week, suddenly became nothing at all. That was down to me. Odd I know. Chloe knew we did it, what we did and that we filmed it. With her back in the house, I didn't know what to do. After a little over a week, Stuart couldn't hold out any longer. It started as an almost silent mutual masturbation session. It was never going to end there. We both needed relief. As we'd refrained for the performing, when it came, the fuck was hard, fast and loud. Sometimes you just need it and can't help it. The fallout in the morning was loud and vociferous.

"Not fair. I didn't barge in. I was stood outside waiting to be invited. Didn't you hear me knocking?" Chloe said.

We hadn't. Probably drowned out by the squeaking of the bed springs and the rocking of the frame. She was serious. She really was expecting to watch us have sex. It was like two businesses negotiating a deal. Proposals went back and forth. Little by little the concessions were all on our side. The only one she made was not to tell anyone.

That's how we ended up in this unconventional situation. A lot of our sessions when she was away had been spontaneous. We did it when we felt like it. What we did was a spur of the moment decision. Now, sessions were planned. She'd be invited. Initially, she could sense my discomfort with the situation. My worry that Stuart would see here as a younger version of me and things would get out of hand. I can't believe it but I actually said this to Chloe, when we were alone.

"Not going to happen. I don't have many boundaries but that is one. Like I've told you, I like watching. Dad's not fucking me and you're not licking my pussy. Although, I might have to rub it."

It didn't reassure me that much.

The first session was somewhat tense. What I hadn't taken into consideration, was that Chloe would be as naked as we were. It was like looking into a timeshift mirror. She could be me, twenty years ago. I tried not to look too closely by I couldn't help the occasional glance and making comparisons. Stuart was far more open about it.

"Nice." He said, before I managed to get him to focus on me.

"Beautiful knob. Wide and I like the ridge round it." Chloe countered.

As if he was playing up to her, he ran his finger round the base of his glans. Trying to bring things back into focus, we moved to the bed, kissing and cuddling. I know that she's seen that and way more but it didn't make me any less nervous, with her in the room. Even more so, as Stuart's hand moved between my legs. For a second or two I resisted but that was never going to last. A minute or so later, I returned the gesture by slowly stroking his cock. As things moved on, I could sense but not see Chloe moving around. Getting a better or different view? I was determined to keep things fairly vanilla. Stuart fingered me to a couple of orgasms before we fucked and he came in me. My thoughts would align enough for me to cum while we fucked, something that happens most of the time. Even if it takes a bit of clitoral stimulation. That didn't do it today. Stuart knew the signs and stopped. Chloe said nothing, walked to the door and left.

As time progressed, we left our door open. Chloe would come in if she wanted to, which was more often than not. The first time she'd just watched but on every other time she came in she masturbated to at least one orgasm. Sometimes stood close to the side of the bed. Something I couldn't manage. I've never got off standing up.

Her masturbation wasn't all that changed, she started asking for things. It was as if we were performing for her and not our pleasure. The results were the same, the three of us getting off, sometimes multiple times a night. We'd hear,

"Suck his cock..... Tongue her clit...... Wank his cock, make it spurt..... Put it in her bum."

That was one of the things, I wouldn't admit to doing. I always lied when my friends mentioned it. Although, Chloe will have seen several videos of us doing the unmentionable. It took several years before Stuart plucked up the courage to ask if we could do it. Like everything else, either of us had suggested, we gave it a try. It felt like a red hot poker was stretching me open. On my knees, I remained still, my hands grasping the duvet while he did it. I was grateful to feel the expulsion of his cum into the wrong hole. His withdrawal left me feeling open and vulnerable. He sensed it instantly. That night he held me tighter and for longer than usual, before sleep overtook him. He didn't ask to do it again.

I hate to admit it but it was me who initiated the next and subsequent insertions into my bum. A drunken night out with my friends and a conversation, during which I kept silent, was the spur. I've no idea if it was a change in my attitude or my body but it's something which I shouldn't enjoy but definitely do. Chloe won't have failed to notice that more often than not I'll orgasm with Stuart's cock in my bum. He does but less so. I don't know if it is the memory of that first time that holds him back but he often ends up stroking his cock to finish. It looks impressive on the videos but I'm sure isn't as satisfying for him.

Chloe seemed to have a particular liking for watching that. The degradation of her mother? A fascination with bums? Knowing it's taboo? She never did say.

What she did say was,

"Tried it with Shane but he's way too big. Couldn't do it."

Thinking about our daughter even trying it made my blood run cold. How big was too big? Had she tried it, just because she'd seen us on video? All sorts of things crossed my mind. I began to wonder if we had corrupted our own daughter. Or whether watching our videos was just an extension of what she'd already found to her liking. Whatever the case, I didn't want to discuss it. She'd try and coordinate her orgasm with mine. She'd keep going until Stuart had stroked his cock and sent his cum shooting over my bum and back.

I have a lot of worries. Firstly, about what we are doing now. It surely isn't right to let your daughter watch you having sex? Less still to follow her instructions, showing her exactly what she wants to see. I think this is more of my problem than Stuart's. He doesn't seem too bothered by it. I know that he's not going to do anything with Chloe but he does seem to like to watch her as she cums. She's far less quite and much more expressive than I am.

I can't help thinking about what she's going to be like when we aren't around. Although, it isn't our problem, it worries me. You want to take care of your kids and do the best for them. However, dealing with this is beyond anything we are able to deal with. Chloe's attitude,

"Something will turn up."

How you can know that, I'm not certain. Finding people who are happy to have sex while you watch isn't an everyday problem. At least for now, we'll carry on.
