I enjoy flicking through my scrapbooks because they contain all sorts of personal memorabilia that remind me of happy events throughout my life. There are concert tickets, family photographs, scribbled notes and poems, plus love letters and drawings. When I lost my virginity just after my eighteenth birthday, I quickly became sex-obsessed, and my scrapbooks began to fill up with reminders of my sexual encounters as well.

My other great passion is art, and I love drawing pictures of all sorts of things. My interest in erotic artwork began when I joined a club where they held a monthly life class with a nude model. I became quite proficient at drawing the male and female form.

They were very innocent studies whereas nowadays, most of my pictures are much more explicit.

One of the female models that sat for us in those days was a lovely woman called Carol Bridges. She was around forty when I knew her, and she lived just round the corner from my parent's house with her daughter Tara. In her late teens and early twenties, she was one of the nations’ top glamour models and regularly featured in newspapers and men’s magazines. When she was in her twenties, she was famous for her trim figure, large firm shapely breasts and huge sex appeal, none of which had significantly changed over the years.

A few weeks ago, I came across a nude drawing that I’d made of Carol at one of those sittings, together with a centrefold from a magazine at the height of her popularity. The two images were so different in the sense that my pencil study of her breasts was tasteful and classic whereas the centrefold image was highly explicit with no attempt at modesty. The entry was dated just a couple of months after my first real sexual encounter and, when I looked at it, the memory of a surreal event flooded back.

She frequently attended the lingerie and sex toys parties that my Mum hosted, and I’d got to know her quite well. Then when Tara turned eighteen, she came along too, but she was quite a moody girl, and we never really became friends.

A few days after the art class when Carol posed for us, I called round to her house on the off chance to show her my drawings.

I knew she was comfortable being naked so it didn’t really surprise me when she answered the door wearing nothing but a stylish gold chain and a broad smile. However, when she led me into the lounge where a young man was reclining naked on the sofa with a hard-on, it did cause a sharp intake of breath. I knew that she’d been divorced for some years ago so it was none of my business who she had sex with, but I was somewhat taken aback when she introduced him as Tara’s boyfriend who was staying with them for a few days.

He was a very fit looking young guy about the same age as me or perhaps slightly older and, although I’d heard about this kind of attraction between mature women and their daughter’s boyfriend before, it was still a bit of a shock.

As it turned out, though, there was much more to it than that.

“Callum’s been a naughty boy,” Carol said sternly, “and I was just about to punish him.”

She winked at me when she said it, then went on to explain that after Tara had left for work that day, she’d caught Callum masturbating in her bedroom. That in itself wasn’t really an issue, but when Carol saw that he was looking at the same explicit image of her that was now in my scrapbook, she wasn’t best pleased.

She said that she was so angry that she slapped him across the face then snatched the magazine away before storming downstairs.

When Callum came down sheepishly a few minutes later, he was most apologetic, but Carol had calmed down a bit by then and invited him to sit next to her on the sofa.

They talked about it at some length, and Callum was clearly upset by what he’d done, but Carol was beginning to feel guilty about overreacting. She stroked his hair asking him if he’d taken himself to a climax, and when he said that he hadn’t, she felt that she needed to do more than just console him.

That’s when she suggested that just this once, she’d be willing to do it for him.

“We’d just got undressed, and I’d given him a few initial strokes when you rang the doorbell,” she said. “But I can’t leave the poor boy like this so I hope you don’t mind if I finish what I started. I’m sure Callum won’t object if you want to stay and watch. ”

Since this opportunity might never arise again, he was clearly not going to refuse, so I sat down on a sofa opposite them, and prepared myself for this weird spectacle.

Callum looked at me as Carol cradled his balls in one hand and began to pull on his cock gently with the other. I know it’s a strange thing but I have this vivid memory of her beautifully manicured crimson nails gleaming as she stroked her hand up and down his rigid cock.

It was beginning to turn me on, and I instinctively lifted my short skirt where my finger soon found my neat slit. I wasn’t wearing any panties so there was no barrier to me probing my own pussy, which by now was getting lovely and wet. I slipped my middle finger deep into my vagina and noticed both of them watching me as I sucked it dry.

Callum then reached over with his hand and began squeezing Carol’s fabulous big tits, which she didn’t seem to mind at all. She then shifted her position and knelt on the sofa with her face just above the tip of Callum’s engorged penis.

“I hadn’t intended to go this far,” she whispered, “but I haven’t sucked a cock for ages, and I just can’t help myself.” She then tenderly licked all around his glans before taking it into her mouth.

Callum groaned softly as Carol began sucking him, and when he reached between her legs in an effort to find her pussy, she parted them slightly to give him better access. She was clearly happy to let her daughter’s boyfriend play with her cunt and, when her legs began to tremble, she told him quite firmly not to stop.

After several minutes of expert cocksucking, she slowly disconnected her mouth but kept a firm hold of Callum’s saliva soaked cock in her hand. She looked directly at me and said softly, “ I know I shouldn’t be doing this Candy but I just so want to be fucked,” and in a smooth seamless movement, she straddled him in a reverse cowgirl position.

She guided the tip of his meaty cock into the entrance to her vagina, and I watched it disappear completely into her beautiful body as she sank down on it. She leaned forward putting her hands on his thighs close to his knees and began to ride him energetically. Her lovely big conical shaped tits were hardly moving as all the power came from her hips, and she was making wonderful feminine grunting sounds with every rhythmic stroke.

She tossed her glossy mane of brunette hair and glanced over her shoulder. “God Callum,” she gasped, “Your cock feels so big inside me. My daughter’s a very lucky girl.”

Then she glanced over to me and said, ”What about you Candy, would you like to try it for size?”

“I thought you’d never ask,” I replied softly, and then I swiftly stripped naked.

By the time I joined them, Carol was leaning back against Callum’s chest, and he was holding her tits firmly. She had fabulous long nipples that were really stiff now and just too tempting to resist. I had no idea how she would react when I started sucking them, but when she saw me doing it she smiled at me.

“I didn’t know you were into women too,” she whispered, “I love girls who love girls.”

I doubt Callum had any idea until now just how hot his girlfriend’s mother was, but he was rapidly finding out.

And now I knew that she was receptive to the female touch, I slid my hand slowly down her torso, and started gently rubbing her clit.

Callum’s cock was glistening with her succulent juices as it slipped in and out, and a couple of times she withdrew it completely with an invitation for me to suck it. She tasted delicious, and I made the most of every second by sucking his shaft deeply before she slipped it back inside her vagina again.

She was certainly in no hurry to let me have my turn, but eventually she lifted off and stood on the sofa with her legs either side of him pressing her pussy hard against his face. As Callum started licking her wet womanhood, I straddled his thighs and guided his slippery cock into my young tender pussyhole.

Carol was right, his cock really did feel big and I could feel the tip touch against my cervix every time it was inside me up to the hilt. I grasped his torso just below his armpits and found it easy to bounce up and down on him. Carol was stroking his hair as he licked and sucked her soft pussy lips, and when his tongue found the inside of her vagina she gasped;

“I love what you’re doing to me, Callum. Is this how you lick my daughter?”

With a mouthful of luscious pussyflesh, it wasn’t easy for him to articulate an answer but he sort of mumbled positively, and we both took that as a ‘yes.’

Carol was orchestrating the encounter and knew exactly what she was doing. She asked me to lie on my back, which I did after we all disconnected, and she immediately went down on me. She started nibbling and licking my pussy lips, and in the position she was in with her rear end presenting such a glorious vision of femininity, Callum was soon fucking her rhythmically.

Carol slipped a couple of fingers into my warm wet vagina as she sucked my stiff clit, and the sensation was turning me inside out. She paused only to ask if I’d ever had a woman lick my cunt before, and I replied softly that I had, but not like this.

“I think it’s going to make me cum in a minute,” I whispered.

She became even more energetic with her sucking and fingering until she could sense the subtle signals that told her I was on the verge of orgasm. She teased me by slowing right down almost to a stop, but she knew that I was simmering inside, and it was only a matter of time before she brought me to the boil.

She gradually increased the tempo, and I began to feel my nerves tingling then suddenly my body jerked as though I’d been electrocuted. I gasped out loud as waves of ecstasy pulsated through my entire body, and I could feel my toes curling with the sheer intensity of a wonderfully satisfying orgasm.

Carol didn’t stop, and I enjoyed some lovely aftershocks, but she then turned her attention to Callum who was clutching her hips and fucking her energetically. “Put it in my ass,” she commanded firmly, “Put it in and give it to me hard.”

There was only a slight time lag before she raised her head and winced slightly so I knew he’d penetrated her, and as he went deeper, her expression changed to one of joy. “I love anal sex,” she whispered as Callum started to fuck her cautiously, “It feels so different.”

Then she asked me if I liked it and I confessed that I hadn’t tried it yet.

“There’s no time like the present,” she said, “That’s if you want to.”

“In for a penny, in for a pound,” I replied enthusiastically.

Again, she was in no hurry to give way to me but by way of preparation, she started to gently finger my puckered sphincter and, after a few minutes, she asked me if I was ready.

“I’m ready,” I said slightly nervously. She asked me what position I wanted to adopt soI thought about it for a second and replied, “On my back.”

As I was already in the right place it was just a case of Callum getting between my legs, and slipping his stiff cock into my asshole. Carol suggested that I hold my legs up with my arms behind my knees to give him the best access, and she told Callum to be very gentle because I’d be very tight. I thought it would be simple, but it took a lot of Carol’s spit together with plenty of encouragement with her hand before my sphincter relaxed sufficiently to get the tip of Callum’s cock into me.

There was brief stabbing sensation at first, but once my rectum began to dilate, Callum was able to penetrate me inch by inch until he was all the way in. His gentle fucking soon expanded my tunnel, and before long his strokes became long, deep and rhythmic.

The feeling was sensational, and I completely understood what Carol meant about how different it was. I couldn’t help the primitive grunting noises I was making as Callum tenderly broke me in, and I was so relaxed by now that I was able to let my legs down. It was lovely to feel his body pressed against mine as he lay on top of me kissing me passionately.

I think both Carol and I were impressed with Callum’s stamina and self-control, but there comes a time when a man needs to cum, and when he announced that he was getting really close, Carol took over again. She told him to withdraw from me and sit on the edge of the sofa then she knelt on the floor one side of him resting her tits on his thighs, and I took up a similar position on the other side.

Even though she knew where his cock had just been she had no hesitation in sucking him deeply, and over the next few minutes we shared his throbbing cock between us until he gasped, “I’m cumming.”

As I massaged his balls Carol tugged his cock, and we both had our extended tongues touching his shaft just below his glans waiting for his imminent ejaculation. The familiar sound of a man reaching orgasm was followed by an eruption of warm creamy cum that cascaded rather spurted from his tiny duct. I could feel his balls twitching as his prostrate gland pumped his messy load into our mouths and over our hands.

I love the flavour of semen and clearly, Carol did too as we competed with each other to consume as much as possible. When it became obvious that Callum had little left to give, Carol and I sucked him dry and swallowed every drop.

“We got there in the end, Callum,” Carol panted, “sorry it took so long.”

She noticed some cum dripping off my chin, which she scooped up with her finger saying, “What was it like for you, Candy?”

“Unexpected to say the least,” I replied, “but I wouldn’t have missed it for the world.”

“Shall I make us all a nice cup of tea?” she then asked bizarrely.

And for some equally bizarre reason, both Callum and I said, “That would be lovely.”

Once we were cleaned up and fully dressed again, we all seemed to resume a state of complete innocence and made no reference to what had just occurred. I showed them my drawings, which they both thought were very good and Callum demonstrated what a charming young man he was.

When it was time for me to leave Carol handed me the magazine that she’d snatched from Callum earlier that day saying that I could keep it as a keepsake. I formed the impression that the steamy events of the last ninety minutes or so were a complete one-off, and would never be repeated in any form.

Until she moved away, I encountered Carol many times after that day, but there was never any mention of what we experienced, and I learned some years later that Callum and Tara were married with a couple of kiddies.

As I was concluding this story I asked myself a hypothetical question. If I suddenly found myself in a room alone with Carol and Callum and they were up for it, would I be interested in re-enacting the events of that day?

Now there’s a thought.
