And I couldn't tear my eyes away from the screen. She was so calm - and so deliberate. I watched with a mixture of horror and fascination as Mum Onscreen put the whole condom in her spunk-filled mouth and rolled it around with her tongue, chewing on it at times, then letting it protrude obscenely between her shiny lips, and dribbling spunk out and slurping it up again. The scene went on for hours, I felt. And I desperately wanted it to end. And I wanted it to continue forever.
When the clip had finished, I realised Mum was watching me. She patted my thigh. 'Are you alright?' she asked. 'You've gone a bit pale.'
It didn't surprise me. To be honest, I think I may have been close to fainting.
'I told you it was going to be dirty,' she said. 'But you get what I've been saying now, don't you? This kind of porn is all about shock. And I think I've shocked you now.'
I shuddered and she leaned towards me and kissed my mouth, bumping me with her shoulder.
'I think you need some release,' she said. 'But I'm going to bring myself off first. It'll be sexier for you to watch me before you cum. Is that alright?'
I nodded wordlessly.
Mum didn't do anything elaborate. She just put her hand back in between her legs and worked her fingers in her cunt. She kept on looking at me the whole time, with a half-smile on her lips. She took her time over it, though. I could see she was working herself up slowly. After a couple of minutes she held her middle finger up - the middle finger of her wanking hand - and I could see a gossamer filament stretching from it to the tip of her index finger.
'Open your mouth,' she told me. And when I did she popped her fingers in.
'Lick it off,' she said, gently. 'Taste me. Taste my cunt'.
So I licked her fingers clean. It was yet another filthy moment between us.
Then Mum went back to masturbating and after a while I saw her fingers begin to move faster and her face contorted. Then she groaned through her grimace and she shuddered. The shudder went on for ages as her orgasm passed through her.
When it had finally finished, she took a deep breath and gave what I can only call a merry laugh. She took her hand off her cunt and stroked my cheek for a moment with damp fingers.
'I really am a nympho,' she said. 'You can see that, can't you?'
Then she took my stiff prick in her hand and began to wank me off.
She was careful. I was on a hair trigger - in fact, I don't really understand why I hadn't cum already. My cock had certainly been leaking for a long, long time. But Mum's touch was very light and she seemed to know instinctively when I was on the verge of orgasm. At those times, she stopped suddenly and let the rising spunk subside. Then, when she thought I could take more, she started to play with me again.
I don't know how long this went on. Maybe it wasn't very long, but I'd lost my sense of time. I was lost in my mother's eyes as she teased my cock to the brink. But, at some point, she said: 'Let's make this kinkier, shall we? Have you still got those knickers I gave you?'
I'd put her little thong in my pocket and my jeans were on the bed. I reached across - the bed was close to us - and hooked the jeans towards me. Then I rummaged in the pocket and pulled the black thong out. Mum held out her hand and I gave it to her.
'I - I thought you had a customer,' I stammered.
'Oh, he can have the next pair,' Mum said. 'Now, what can we do with this?'
And lightly, delicately, she let the almost weightless garment fall across my straining cock head; then she wrapped it round my shaft and balls. She spent a while arranging the material to her satisfaction. Then:
'Let's get it spunky,' she whispered, and she began to wank me again, much harder now, with long, firm, insistent strokes.
When I came, the first spurt shot up high in the air, and it fell back on her fingers, still wrapped firmly round my prick. And then there was another spurt, and then another. By the time I'd finished cumming, her fingers were coated with my spunk and the little black thong was soaked with it.
She sat there, holding my sticky cock for a while, smiling at me. And then, very deliberately, she released me and brought her hand up slowly to her mouth, never breaking eye contact with me. Her pink tongue darted out and she licked her spunky fingers. She did it methodically, adjusting the angle of her hand so she could lick each finger and her thumb and the back of the hand in turn. And she went on doing that until her hand was clean. It reminded me of a kitten cleaning its face with its paw. I saw my spunk gleaming at the corners of her mouth.
She grinned at me, and as her lips parted, I saw a thin string of sperm stretch out between them. But she hadn't finished. She reached down to my prick again and disentangled her thong from it. And then she raised the spunky material to her mouth, stared hard at me for one beat - maybe two - then popped the slimy thing inside. She sat there with the sticky strings dangling down below her chin.
'Dirty enough for you?' she asked, with the thong still in her mouth. And, yet again, I nodded dumbly.
*****
I slept late the next morning. I didn't wake up 'til ten o'clock. As I was crossing the upstairs landing to the bathroom, there was a ring at the doorbell and I heard Mum open it. Then I heard Millie's voice. They both laughed excitedly.
I hadn't been expecting Millie and I was curious about what she was doing there, so I lingered on the landing and eavesdropped. I heard Millie ask: 'Is Brian here?' And Mum said 'Yes,' with a kind of giggle in her voice. Then Millie asked: 'Have you let him fuck you yet?' And Mum said, 'No, but I wanked him off last night. And we played some games too - piss games and spunk games. It was lovely!' And Millie said: 'Ooh, you dirty cow, Mummy!' and they both laughed. Then they must have gone into the kitchen because I didn't hear any more.
I had a quick shower and cleaned my teeth and so on. While I was in the bathroom, everything that had happened the previous night came back to me. I got an instant hard-on the moment I stepped inside and it didn't leave me after I'd dressed and gone downstairs. I more or less hobbled into the kitchen, with my stiff prick pushing hard against my pants.
They were both in there. Millie, who was sitting at the table drinking coffee, waved to me casually and said 'Hi'. She pointed to my crotch. 'You're a perky boy this morning,' she said.
I'd normally have been embarrassed but, when I noticed Mum, all thought of that disappeared. She was standing at the sink, washing some dishes, and she was still wearing the red wool sweater she'd put on the night before. And - just like the previous night - she wasn't wearing anything else. Her arse was bare. And when she turned round I saw her pussy too. Mum just smiled. 'Coffee?' she asked. It was all I could do to say yes. She made me a cup, moving around the kitchen and flirting her lovely bum at me - well, at us I suppose, because Millie seemed to be enjoying the performance as much as I was.
When she'd given me the coffee, Mum came and sat down at the table next to Millie and casually took her hand, and held it in her lap against her cunt. Millie didn't turn a hair. She was grinning broadly, and I realised she was delighted at the effect the two of them were having on me.
'Still feeling perky?' she asked - and there was nothing I could say, because I was, indubitably, completely tented up. In fact, my erection was raging, almost painful.
Mum looked directly at my bulge, then she glanced at Millie. 'We really ought to do something about that,' she said.
Then she turned to me. 'You need a good wank, Brian,' she said. 'And we'd love to watch you. Why don't you do it now?'
'Now?' I said. (I was back in echo mode.)
Mum gave me her sweetly reasonable smile, and Millie grinned broadly, cuddling up against Mum and laying her head against her shoulder. Mum was still holding Millie's hand against her cunt, I noticed.
'Go on,' said Mum. 'Get it out. You know you want to. You can shoot off on the table. It won't do any harm.'
Now, the things I'd done last night with Mum had been pretty extreme, but I was suddenly plunged into a new situation here. I wasn't at all sure about wanking in front of the two of them. But Mum said: 'Come on, darling. Don't be a spoil-sport,' so - a bit shame-faced - I stood up in front of the table and unzipped and took my cock out. Millie cheered when she saw it, but I thought she was taking the piss.
'Go on, darling,' Mum said. 'Give us a show.'
There was no turning back now. I started to masturbate.
It took me a long time to cum. While I was wanking, I noticed that Millie's fingers were moving against Mum's cunt and I realised she was actually trying to bring Mum off. Mum leaned back in her chair and spread her thighs and watched me through half-closed eyes while Millie rubbed her. And, around then, the sheer dirtiness of the situation hit me: I was masturbating over the kitchen table while my mother watched me and my sister frigged her off. And I noticed that Mum's face was turning pink and her bum was squirming on the chair as Millie's fingers worked at her. I think we came together - or not very far apart, at least. I saw Mum's lips form a little 'o' and she threw her head back and clenched her thighs on Millie's hand and moaned. And my spunk shot out and landed in a sticky slash across the tabletop.
Millie looked at the table and then up at me - and she extracted her hand from between Mum's legs and put her fingers to her lips and sucked them. And Mum stood up. She said: 'Over to me, I think. Don't you?'
I was standing there with my sticky cock in my hand. Mum leaned over and put her face on one side, very close to the table top. Then her tongue snaked out and she began to lick at the semen. She looked so serious - so intent! And so deliberate! She was bathing her tongue in my spunk! She was sucking it up!
And then Mum stood up again and looked at Millie. There was an almost mad invitation in her eye. With a full mouth, she mumbled: 'Do you...?' and Millie nodded, and Mum leaned down and kissed her gently, just a closed mouth touch of the lips. Then she drew back a little and Millie threw her head back. Her lips parted. Mum leaned over and took aim and released a viscous glob of spunk and spit. It fell slowly, heavily, into Millie's open mouth. Then Millie reached up and kissed Mum again, and I saw Mum's spunky tongue worming itself against hers.
After a while Mum broke the clinch and stood back. Her mouth was shiny. So was Millie's.
'So that's the basic cumswap,' she said - to Millie, not to me. 'There's nothing to it really, but it's incredibly popular. Of course, the end result depends on the photographer a lot, but if he gets it right, the pictures can be fantastic.'
And Millie said: 'Alex is going to be taking the snaps. She's really good. We'll try this out next week.' And she wiped her mouth with the back of her hand.
Then, to me: 'You don't fancy being a stunt cock do you, Bri? I'll be needing quite a lot of sperm next week.'
*****
I was completely in the dark. There was obviously a lot of explaining to be done. The story came out in the kitchen while we were calming down after I'd masturbated for them.
Mum was pottering about as mothers do, wiping what was left of the spunk off the table and then rinsing the rag.
'What was all that about?'I asked. 'The stuff you were saying to Millie?'
'She's starting a website of her own,' Mum said. 'Aren't you darling?'
Millie explained: 'I got the idea after I found Mum's site. Alex is keen on it too. But we didn't really know how to go about it, so I decided to phone Mum and ask for advice. And, of course, I obviously had to tell her I knew about Sexy Anna - and I told her I'd told you as well while I was at it.'
'I was thrilled,' Mum broke in. 'I have to say, I'd been a bit nervous about the two of you finding out, so it was a big relief to hear that Millie was so, shall we say, enthusiastic about it.
'And I was glad she'd told you too, Brian,' she went on. 'I didn't like having secrets from you both, especially since you're grown up now. I should have told you about the site that time you came for Christmas, I suppose - when I told you I'd done a bit of porn in Germany - but I chickened out. I knew you'd have a pretty complicated reaction, of course. I had to think about that. But we couldn't go on pretending the website didn't turn you on, could we? Because it obviously does. So I decided to meet you head on. If you're going to have dirty fantasies about me, I think we ought to act them out together. So that's what I've been doing.
'And I'm enjoying it too,' she added. 'I love seeing you get all hard and excited over me.'
'So you're teaching Millie how to do porn?' I said slowly, as the pieces began to fall into place. 'You're sort of tutoring her?'
'That's right,' said Millie. 'And she's a bloody expert, of course. But you've probably realised that already.'
'But I thought you liked girls,' I said.
'I do,' said Millie. 'But I like boys as well. It's Alex who's the total lezzie, not me.'
'Mind you,' said Mum, with a big grin, 'Millie's pretty good at the lezzie stuff. Aren't you darling? I'm enjoying that part of the tutoring a lot.'
And Millie did her cat's-got-the-cream smile again while I took in yet more exciting, shocking news about my family.
*****
A bit after that, Mum went upstairs to do something on her website. When she came down again, she looked thoughtful and a little tentative. She said: 'I don't want to impose on the two of you, but I wonder if you'd do me a favour? It's for the site.'
And of course we both said yes - though I for one had a sudden knot in my belly wondering what she wanted.
'I've just had a request,' Mum went on. 'You know I do members' requests don't you?'
We did. I'd actually been thinking about her requests page for ages, and I'd been tempted to send one in myself. I hadn't done it though.
'This one's actually fairly easy,' Mum said, 'but it'll take the three of us. The bloke - I think it's a bloke - wants me to walk round a shopping mall with dried semen on my face. That's all.'
I'm pretty sure I gasped. I noticed Millie had gone quiet. I think she was a little shocked.
'So, what do you want us to do?' I asked.
'Well,' Mum said. 'I thought Millie could do the camera work - it'll be good practice. And you'd just have to cum on my face. I'll give you a suck first to get you nice and hard,' she added. 'And we'll keep your face out of shot, of course. It'll just be me and your cock and your cum.
'After you've spunked on me, we'll go to the mall and walk round a bit, with Millie filming. It'll look just like a family outing. I'm sure no-one will notice the spunk.
'There's a nice coffee shop at the mall, by the way,' she added. 'We could have lunch there afterwards, if you like.'
*****
It was much more complicated than I expected. First off, Mum went upstairs to choose the right clothes for the occasion. That took a while. When she came down again, she was wearing a light green summer dress with shoulder straps and strappy sandals. She looked very nice, but quite conservative and rather elegant - not at all slutty. As she came in, though, she pulled the skirt of the dress up and gave us a twirl. She wasn't wearing panties underneath.
Then Millie had to set up the equipment for the spunk shot. That took a while. They were both very serious about it, doing tests with a light meter and so on. I know hardly anything about photography, but they both seemed surprisingly expert.
We shot the first scene on the sofa in the living room. Mum sat there and sucked my cock for a long time. (It was gorgeous, by the way. Her mouth was so warm and wet and soft.) It was a bit strange having Millie so close to us, though. She had the camera almost in Mum's face a lot of the time. But I got more relaxed as the scene went on - because Mum was so good with her tongue and I was loving every minute of it. Eventually, I more or less forgot about Millie and the camera.
Then we did the cum shot. I think Mum had been careful not to let me shoot in her mouth. I was beginning to realise how professional she was - and that was surprisingly sexy in itself. When it was time for me to spunk off on her, she leaned back against a cushion - a big red one - and Millie messed about for a while, framing the shot. When they were ready, Mum told me to step forward and put my cock in frame, over her face. Then she smiled up at me - well, at my cock, I suppose - and told me to do it in my own time. 'You'll have to wank it, darling,' she said. 'These things never work properly when they're spontaneous. But I'll give you a proper blowjob soon, I promise.'
So I wanked off into her face, and I surprised myself. I'd already cum once that morning and I was a bit worried that I wouldn't produce enough, but I actually came in three or four big spurts. The stuff coated Mum's mouth and cheeks, and it clung to the lashes of one eye, and some went into her hair as well. When she sat up afterwards, a string of my spunk fell from her chin and dropped onto the bodice of the green dress. Although it had been such a huge cum, I thought it wouldn't be any good for what she had in mind. There was too much. She'd never be able to go out in public like that.
But she just asked: 'How does it look?' And Millie said: 'Great!' And Mum went to the mirror in the hall and had a look, and nodded and pronounced herself satisfied. She did wipe the goo off her eyelash - very carefully, with her thumbnail, as if she was adjusting her make-up or something. But she left the rest as it was.
'Shall we go to the mall, then?' she asked brightly. 'I'll drive.'
In the car, Millie sat in the passenger seat with the camera, filming Mum from the side, and I sat in the back, out of shot. I couldn't believe we were doing this. As far as I could see in the driving mirror, the spunk on Mum's face was still obvious, even though it had dried now. There were crusted deposits of the stuff on her cheek and round her mouth. I couldn't see the stain on her dress, but I thought that would be obvious too.
When we got to the mall car park, I asked her a bit nervously if she didn't think she should clean some of it off. But Mum said: 'No, it'll be alright. You'll be surprised how little people notice. That's the attraction of this kind of fetish. If you know what's really going on, it's dirty. But if you're an innocent bystander, there's nothing to think about at all. It's just like going out without knickers on. You know I'm not wearing any, so you know I'm a dirty slut. But the people in there' - she pointed towards the mall - 'will have no idea.
'Unless I flash them, of course,' she added, as an afterthought. 'I might just do that,' she grinned.
Mum walked round the shopping mall for about half an hour - and she was right: nobody paid her any special attention. I lagged behind and watched from a distance. I noticed a few blokes checking out her arse - but that was normal, I should think. Millie drew a few looks, because she's hot and because she had the camera. But nobody took much notice of her either. Mum just wandered about, window-shopping, admiring the reflection of her spunky face in the glass. Then, when they thought they'd recorded enough, we went to the coffee shop for lunch, and Mum sat there smiling, with the dry spunk still on her face. I could see where it was quite plainly. And we chatted while we ate - just chit-chat; nothing sexy. And then we all went home.
When we were in the car again, Millie asked: 'I thought you were going to flash somebody?' And Mum said: 'I did. Don't you remember, I was behind you when we left the café? Well, I opened my legs and hiked up my skirt for the bloke at the table next to us as I stood up. He'd been staring at me for ages. I gave him a quick look at my cunt. He looked quite pleased. I bet he brings himself off over me tonight.'
