With trembling fingers, I began to scroll through the pictures. The second shot was much the same as the first, although Susan was now leaning forward and licking Ella's right cheek with the flat of her outstretched tongue. Helen looked into the camera lens with a perverted smile on her face as she raised Ella's tutu to show that she wasn't wearing any knickers, her hairless, puffy preteen cunt fully visible. Rachel was now squatting down next to Helen and was pulling her left nipple so hard that her whole tit was stretching to follow. I estimated that her tit was pulled a good two or three inches out. Clearly she was turned on.

The next picture showed Helen and Susan licking Ella's cheeks and the trail of saliva they left behind glistened like silver. I could also see that my wife had her hand between Ella's legs from behind, her middle two fingers clearly resting on Ella's cunt. Fucking hell, this was some amazing stuff! For the second time in the space of half an hour, I thought about my expectations before leaving home. A photo of Susan in her bikini would have counted as a major success.

Now I was viewing hardcore child porn, performed by my sister in law and now, my wife. Well, maybe hardcore was a bit of an exaggeration for my wife touching Ella's four year old cunt, but I wasn't about to argue, especially as the photographer clearly knew what they were doing.

And then, it hit me. If Susan and Helen were posing together, then who the fuck was taking the pictures? Will? Surely not? As nice a bloke as he was, he was limper than a soaking wet newspaper. He couldn't fight his way INTO a paper bag, never mind out of one. But someone had to be taking the pictures. My mind raced. A professional photographer? A friend or family member? Not that it really mattered I suppose. The pictures were fantastic who ever was taking them, but I was curious.

I let the thought drift away as I moved deeper through the folder. My cock, still protruding from my flies and covered in rapidly cooling semen, began to twitch as the images on screen became harder and harder. I pushed my trousers and underpants down to my ankles, freeing up my cock and balls. Ella was now lay on her back on the dining room table and Susan and Rachel held her by the ankles, spreading her legs as wide as they could. Ella's fairy outfit was now reduced to her plastic tiara, a pink t-shirt that proclaimed "Fairy Princess" and a pair of pink, sequinned ballet pumps. Helen was squatting down between her legs and was spreading her hairless cunt with her fingers. The pinkness of Ella's young twat was clear to see, as was the moisture around her hole.

The next shot was a close in of my wife as she extended her tongue and licked Ella out. Helen's eyes were closed and her cheeks were flushed red. Clearly, she was enjoying her work! The next shot got me wanking my cock again. Susan was now on the dining table with Ella, this time squatting over her face with a hand on the back of Ella's neck, lifting her head towards her cunt. My stroke increased as I viewed the next shot. With a sideways glance at the camera, Rachel had replaced Helen and was now licking her own daughter's cunt, the close in shot showing her tongue penetrating her little girl's hole, her middle finger inserted into her tiny, virgin arsehole to the first knuckle.

My brow was now soaked with sweat and I could feel an uncomfortable, cold dampness around my arse and balls from the perspiration. The pictures suddenly stepped up a gear and I felt my cock spasm in a warning of what was to come. Susan was now on the table with Ella in the 69 position. Ella was on top facing away from the camera, her bald twat inches away from my sister in law's face. Susan's tongue was stuck deep into Ella's cunny. Helen was also in the shot, her tongue stuck in Ella's little pink arsehole. Rachel's hands, her distinctive black nail polish identifying them, spread her daughter's arse cheeks to allow my paedo wife more access.

In the next shot Susan and Helen knelt on all fours, facing away from the camera their firm, white arses filling the screen. Ella knelt behind them, her hands raised towards their cunts. Both women looked back at the camera over their shoulders, faces flushed red with lust.

The following pictures were similar, although Rachel was now in shot as she knelt and guided Ella's right hand into my wife's cunt and then her left into Susan's. The following pictures showed Rachel forcing more of Ella's arms into the wet adult cunt holes until, in the final picture Ella was nearly elbow deep in Susan and Helen.

The final two pictures sent me over the edge and I orgasmed for the second time in half an hour. Now naked, save her sequined ballet pumps, Rachel lifted her right leg and placed it on Helen's back, before thrusting her shaven cunt towards her daughter. The final shot showed a stream of bright yellow piss arching out of her twat and hitting Ella in the face. The piss was clearly jetted with some force as the mystery photographer had captured the yellow liquid as it rebounded off her tiny forehead. Droplets were caught in freeze frame as they bounced into the air. I thought I was going to pass out. Ella, four years old and dressed as a fairy, having been licked out and rimmed by three women, one of whom was her own moter, was now fisting my wife and her sister as her mother, her filthy mother drenched her face and hair in piss. I literally felt as though an invisible hand was constricting my throat as I viewed the images. And then it all went wrong. The sound I was hoping not to hear, a key in the back door filled my ears.

SHIT!!!!!! SHIT SHIT SHIT SHIT SHIT!!!! Someone was coming in! Fucking hell. I was sitting in a puddle of my own freshly shot cum, trousers now around my ankles and hardcore paedo images on the computer screen. I panicked. I tried to get up, pull my trousers up and turn off the screen all at once. I failed, miserably. I stood up, cracked my knee on the computer desk turned and tripped headlong over my trousers. The last thing I remembered was a blurred image of the hard wooden edge of Susan's dining table, the same table that had just appeared in the images I had cum to, approaching at speed. I didn't really feel the impact. I just saw a bright light explode behind my eyes then felt a sensation of hitting the floor. And then, nothing.

I don't know how long I was out for, but I came around with a start. My eyes struggled to focus on the blurry figure that knelt before me. I felt a dabbing sensation at my forehead well before the sharp pain came in. As if activated by a switch, the sharp cutting pain filled my head. I instinctively closed my eyes and raised my hand to my head. I heard the voice of my wife, Helen telling me not to touch my head. Oh fuck. Bollocks. Fuck fuck fuck. This was it. I slowly opened my eyes. Helen knelt before me holding a cloth to my head. I had been moved so I was sitting upright against the wall, facing the computer table. I looked over and to my relief saw that the computer was turned off. But then relief was replaced by panic as I realised that Helen must have turned it off. The sensation of panic heightened as I saw that my jeans and underpants were still around my ankles and my sperm covered cock was still out.

"I knew this would happen" said Helen. "I told her to take the stick with her, but she wouldn't listen". I looked up at my wife's face. She looked down at my crotch, "Looks like you had a good time though". I mumbled a reply, deeply embarrassed.

"Why didn't you say anything?" I finally managed to blurt out. "You've been doing this behind my back. Why not say?" With a scornful look, Helen almost spat her words out at me.

"Oh yeah! Like that would have worked. How DO you tell your husband your fucking kids with your sister? Get real".

"So what now?" I asked.

"What indeed" replied Helen. "Are you going to turn us all in to the cops?". I shook my head.

"I want some answers though" I replied.

As I sat, forehead pounding with the pain of the impact, trousers around my ankles my wife told me everything. This whole thing had been going on for nearly eleven years. It was the birth of Susan's first son, Matthew that had activated a latent paedophilic desire within her. Helen explained that within a few weeks of Matthew being born, Susan had caught her father in law, Brian masturbating over her infant sons sleeping face.

Rather than being repelled, Susan had been massively turned on and had actually finished Brian off onto Matthew's face before licking the sperm up. Since that first encounter, her desire had grown stronger day by day. My wife explained that Susan had invited Brian round at every opportunity, but had kept Will, her husband totally in the dark about what was going on. This was still the case to this day and Susan had no plans to change the set up. Helen explained that Susan and Brian had been fucking each other senseless most weeks days and playing with Matthew was a major part of their sex sessions. I thought about the scenario. Brian, 63 years old and not exactly slim or attractive was fucking Susan behind his own son's back.

Not content with that, he was also abusing his own grandson with the boys mother! My wife explained how Susan had sucked Matthew's cock at Brian's request. Aged just 2 months, Susan had sucked her son, rimmed him and had also drenched him with piss, all to satisfy her perverted lover. And it didn't stop there. Susan would do anything that Brian asked her to.

"Anything?" I queried.

"Anything" replied Helen.

Helen continued and explained how Susan used her charm and tact to convert several of her female friends to the same desire. A network of mothers, with sons and daughters of all ages was headed by Susan. She was the spider in the centre of the web. Whilst she provided the fresh talent her father in law, Brian took the pictures and videos and then distributed them among specially selected, paying clients. These clients in turn, submitted orders and paid handsomely for their requests.

This was how Helen had become involved. As we were permanently short of cash It seemed a good idea to agree Susan's request to join her. Helen explained how she had performed her first shoot with Matthew and Robert, then aged 4 and 7 and had sucked both their cocks as Brian photographed them. Not content with fucking my sister in law, Brian had then fucked my wife after the shoot. So not only was Helen a secret, active paedo, she was now fucking old men behind my back. She explained how she had made £300 from that first shoot and had tucked the money away in her building society account. The one that she told me she had closed years earlier.

Just then Helen's phone rang. Taking it from her pocket she answered it.

"Hi Brian" she said, looking down at me. "Yes, he's here........ yes, he found it..... yes....... yes... looks like he's shot a couple of loads to them to be honest........ ok............ ok". She then offered me the phone. Tentatively I took it.

"Hello?" I asked, nervously. Brian's deep voice spoke back from the other end.

"Well now, it seems we have problem young man. You've found us out. Susan has been very careless hasn't she?" I nodded and made an indistinct sound, my throat as dry as sandpaper. "So how to resolve this issue. Helen tells me that you seem to have enjoyed looking at our pictures. Which ones did you cum to? Tell me."

I mumbled into the phone "........The one...... the ones....... Ella..... the ones with Ella".

Brian let out an appreciative "Hmmm. Yes those were good ones weren't they? Well young man, I have a proposition. We need a regular cock. One to join our sessions. Think it over". And then the line was dead. Helen looked down at me. "Think it over" was all she said, before she stood up and walked into the kitchen.
