Stepmum

They’re shagging again - my dad and my new stepmum. They shag a lot, and I watch them through a hole at the back of my bedroom closet. They always leave the bedside lights on, and don’t cover up. I found it a bit pervy at first, but I got used to it. Now it makes me hot, so I masturbate while I watch. Dad’s cock is big, and she’s a small woman. I wonder where she puts it all. They shag for hours, and she comes a lot. I come too, usually. I don’t watch it all - I get tired, but leave the closet door so I can fall asleep listening to them.

Describe the characters and set the scene - that’s what my English teacher always tells us. There’s me, my name’s Jenny and I’m 14. I’m pretty ordinary really, brown hair and eyes, pale skin, figure rapidly turning from a girl into a woman. I do OK at school, got lots of friends, some boys but never gone further than snogging and a bit of groping. Not that I don’t know what comes next - we’ve had so much sex-ed it’s got quite boring.

I live with my Dad, Martin. He’s 45, still fit and (I think) very handsome. We argue, of course, but I love him to bits really and he loves me too. When my mum died a year ago we only had each other. Trouble is, he works away quite a bit and one of my aunts was drafted in to ‘babysit’ me when that happened. We didn’t get on, big time.

We live in an old farmhouse on the edge of town. It’s all dark wood panelling, low ceilings and odd angles. I’ve always lived here so I’m used to it. Visitors bang their heads.

A few months ago my Dad met a woman on one of his trips abroad. Within a few weeks they had married and she moved in. I was upset, ‘cos it spoilt our cosy existence, but I was glad for his sake because I knew he missed (adult) female companionship terribly. He’s a very physical person - he and mum were always kissing and cuddling - and admitted to me more than once that he couldn’t cope without sex. It didn’t squick me.

My new stepmum is called Jane; she was 44 and pretty in a bold, even tarty sort of way. Good figure (almost the same height and shape as me, so much so that we even swap clothes sometimes), curly brown hair, nice eyes, smiles a lot. I took to her in spite of myself, and she made a big effort to get on with me. Well, I thought, no point in starting off enemies, and I’d rather have her looking after me than my aunt. In fact, she gives me pretty much free rein.

Trouble is, she came with an add-on - her 18-year-old son Will. Great hulking thing he is, fit, good-looking, clever, popular - and hardly notices I’m there. He’s not unpleasant to me, just ignores me. I tried flirting for a while, but either I’m not very good at it or he prefers girls his own age. He and his mum are surprisingly close, they have lots of little in-jokes and are always teasing each other affectionately. I can see Jane’s embarrassed by this when I’m around, and she tries to include me, but it doesn’t work. Sometimes I feel very much the outsider in my own house.

Anyway, to the story. I go to a lot of afterschool clubs so don’t normally get home until 5-ish. My stepmum works in reception at a local posh hotel, early shift, so she gets up at 5 a.m. and gets home about 2. Will has finished school, starts university in October, and does bar work some evenings, so he goes out about 6 and doesn’t get home till the early hours, then stays in bed till lunchtime or after. Dad works quite long hours, when he’s not travelling, so you see we don’t overlap that much.

One afternoon the gym club was cancelled because staff were ill, so I rolled up at the house about 3 p.m. and let myself in. All was silent - maybe Will was still in bed and Jane had gone shopping. I got myself a drink of milk and wandered upstairs. Will’s door was open and I heard a quiet moan. Maybe he’s ill, I thought. Probably a hangover. Serves him right. But I’m a nice person underneath so I peeped in to check he was OK. My jaw dropped.

Will was naked, stretched on his bed. His cock was hard and pointing at the ceiling, and it was a very big cock indeed, bigger than Dad’s, as big as any I had seen on the web. Lying next to him, and running her fist slowly up and down the cock, was Jane - his own mother! Her head was level with his stomach and she had one leg hooked over his. She was wearing her hotel uniform - a close-fitting royal blue jacket and short skirt, with black stockings and heels. She likes the uniform, and so does Dad, although I think it looks a bit tarty. She always wears stockings, not tights - she says tights are too hot. Either hold-ups or suspenders. She often ‘accidentally’ shows off her stocking tops when she wants to distract Dad from some paperwork and get him into bed for a shag.

I digress. My eyes were riveted on her hand moving up and down the great pink column. Will had his eyes closed, and Jane’s were fixed on the cock. She murmured something, smiling. I couldn’t stop watching. They obviously hadn’t noticed me. Will’s hips started to buck. His mother’s hand went faster. Suddenly he groaned and a fountain of white spurted upwards, a good two feet into the air. I heard Jane chuckling. The sperm splattered down onto his stomach and her hand. Another gush, as high as the first. Then to my utter shock Jane raised her head and engulfed the head of his cock in her mouth. Will’s body shook and spasmed. Presumably the rest of his cum was now filling his mum’s mouth.

When he had stopped shaking, she took his cock out of her mouth and shuffled up. They grinned at each other and talked softly. She must have swallowed it all. Jane reached down and hoicked her skirt up - hold-up stockings today - then worked her black tanga knickers (she usually wore this style) down her legs. She dangled them into her son’s face, and he caught them in his mouth and chewed them. I knew how damp and skanky my knickers got after a day’s wear - he was sucking his own mother’s dirty panties!

Jane stroked his cock softly, and I saw it twitch and swell. Soon it was hard again. She got on all fours, tucked her skirt around her waist, and climbed on top of him. Will grasped his cock, pointed it vertical, and his mother lowered herself down onto it. Her skirt hid the actual penetration from my gaze, but it was obvious what was happening. Jane gave a big sigh of contentment and shimmied her hips down until all his cock must have been up inside her. She rested her hands on his chest and rolled her hips around, and Will chuckled and put his hands on her tits.

She rode him with increasing vigour. I could hear the slap of her bum against his hips. His hands were kneading her tits roughly, but she seemed to like it. They were gasping words to each other, which I couldn’t make out. Jane seemed to go into an orgasm, and then Will shouted ‘I’m gonna cum,’ and she yelped with delight. I imagined his cock spurting its sperm hard up into her insides. God, I wanted to feel that ...

I withdrew, shaking, worried that they might notice me when they came down to earth. I tiptoed to my room, shut the door, and stood in front of the mirror. I raised my school skirt and inspected the wet stain on my white knickers. I pulled the sodden cotton into my slit and pressed both hands between my legs. The orgasm came quickly and powerfully, soaking my knickers even more.

Weak-kneed, I lay on the bed for a while. I tried to make sense of what I had witnessed. Will and his mum having sex. Wow.

I had a shower and put on jeans and a sweater - unlike Jane, I hate my uniform. Then I pottered downstairs. She was in the kitchen, still in her hotel outfit. She looked flushed and happy, if a little tousled. I wondered if she had put some knickers on, or whether his sperm was even now sliding its way down her legs.

‘Hi, you’re back early,’ she said brightly. ‘You OK, my love?’

‘Yeah, gym was cancelled.’

‘Oh, shame. Want a cup of tea?’

I found it hard to make small talk with someone I had just watched shagging her own son. Not that I was disgusted - well, only slightly. In fact I had found it very erotic, as evidenced by my creaming pussy. In fact, I was sick with envy. Will was a hunk and he could stick his cock inside me any day, 14 or not. I was the same size as my stepmum - well, on the outside anyway. His cock looked awfully large ...

Will went off to work, Dad came home about 7 and we sat down to a meal. Later we watched TV. Dad and Jane sat on the settee - he was trying to watch and she was snuggled against him, one leg over his just like she had done with Will, showing her stocking top. Her hand stroked a growing bulge in his trousers. Not content with afternoon sex, now she wanting more shagging. Soon they made an excuse about an early night and went upstairs. I waited ten minutes and then crept after them, taking up position in my closet. It must have been a connecting door at one time and the wood panelling doesn’t fit together that well.

They were already at it, Jane on her back, naked apart from her stocking-clad legs wrapped around my naked father’s waist. He’s quite hairy, his legs and bum are covered with the stuff - even got some on his shoulders. He was pounding into her with a steady rhythm that I knew they could keep up for ages. They don’t go in for much in the way of kinky sex - maybe a little oral now and then. Mostly it’s just hard shagging, either him on top (mish), her on top (cowgirl), or doggy. You see, I know all the terms. She comes quite a lot. He just comes at the end, then they drag the duvet over them and fall asleep. No cleaning up or anything. There’s a sheet in the wash every day.

I watched for half-an-hour or so, then went to bed and masturbated again. I wondered whether my stepmum’s cunt was still full of her son’s spunk when my father started fucking it. I like using swear words when I masturbate. Fuck, cunt. Fuck my cunt. I came, hard.

The next day, I skipped art club and hurried home, wondering what I might find. I let myself in silently and tiptoed around. This time she and Will were in the master bedroom, so I could watch though my peephole. Jane was on her back, wearing only black bra and stockings, and Will, naked, was lying between her legs with his face buried in her puss. Have I mentioned that she shaves her puss? I’ve seen her naked in the shower - she’s not bothered about modesty - but never plucked up courage to ask her why she shaves.

He seemed to be licking all the right places. She writhed around, twining her fingers in his hair, doing a good line in orgasmic moaning. She could have been a porn star, except I presume it was for real. Eventually Will must have had enough so he knelt up. His cock was huge and hard and reddened. Jane reached out for it but he pulled away, laughing, then held her arms down on the bed. Her cunt was a big wet pink flower between her splayed thighs. She was saying ‘fuck me, you bastard, fuck me!’ and he was telling her to beg for it. She did. She hooked her arms behind her knees and pulled her cunt lips wide apart, opening herself obscenely to her son. I could see the dark hole of her vagina.

Will crouched over his mother and slowly fed his huge cock into her gaping hole. She moaned. In and in it went, until his balls were pushing against her arse. She was impaled on the bed, helpless, skewered. He started ramming into her, slowly at first, then with increasing power. His whole length pumped in and out of her, noisily. Jane came, maybe more than once.

Her son shouted as he climaxed and pounded deep into her. Then he withdrew and his shining cock spurted long white ropes over her belly. It died away to a dribble on her bare puss. Jane put her hands onto the mess and slowly massaged it into her skin. Her hands moved downwards until she was cupping her pubes. Will sat back, watching his mother masturbate. Her fingers slid between her wet, fleshy lips. Soon she bucked and writhed, knowing her son was watching.

He lifted her hands away when she had finished, revealing a white froth covering her puss. She smiled and, holding his gaze, slowly sucked her fingers. That did it for me. My hand had been inside my knickers for a while - I didn’t remember putting it there - and the orgasm just rose and burst inside me. Fresh warmth coated my fingers. When I could focus again I looked through the peephole. Will was lying between her legs again, watching intently as his mother fingered her clitoris. She was obviously going to show him another climax. The smell of her sperm-soaked, orgasmic cunt must have made his head swim.

He twisted two fingers into her hole, pushing them in right to the knuckle, saying something. Jane chuckled. He seemed to be fingering something deep inside her. I guessed he was going for the G-spot - yes, we’d even done that at school. His fingers corkscrewed around inside her harder and harder, until I feared he was hurting her. But my stepmother’s increasingly loud cries of pleasure reassured me. Suddenly her body went rigid, her arse almost lifted off the bed, and a thin clear jet of liquid spurted from her and hit Will in the face. She collapsed on the bed, jerking, while he laughed. Wow, a female ejaculation. I’d read about it but didn’t really believe it happened.

My legs were like jelly so I staggered to my bed and lay down. I didn’t care what they did next. I just wanted the biggest, softest orgasm I could imagine ...

Later, I heard the shower going. Jane spent the evening in her dressing gown, obviously naked under it. Dad didn’t have a chance. She dragged him off to bed as soon as possible and they shagged, as always, for hours. I wondered where she got the stamina.

You might think I should’ve been more disgusted by Jane and Will. I knew it was incest and I knew that it was against the law. But neither of them were related to me, except by marriage, so it didn’t mean a lot. I couldn’t imagine wanting to have sex with my dad, and I didn’t have any brothers or sisters. If Will had been my real brother, would I still have fancied him? Who knows?

Although I would have liked to skip off school early the next couple of days, I really wanted to go to the clubs, so Will and his mum had to do whatever they did unobserved. I watched them carefully when I got home, to see if I could tell whether they had had sex. But there was the usual playful banter and teasing. Maybe they’d been screwing for years, from before my dad had met her ... even from when Will was my age ...

Friday, however, I had a free period last lesson and decided to skip theatre club, so I got home even before Jane did. Will was in his room, music playing. I hid in my bedroom, listening for my stepmum coming back. Yes, that was her, back door shutting, kettle on, then heels coming up the stairs. The music got louder as she opened Will’s bedroom door, and I crept out to peep through the gap. My step-brother lay naked on his bed, cock hard and resting on his stomach. I saw it twitch.

Jane struck a pose and started to do a striptease to the music, flinging her jacket, skirt, and blouse aside. Hold-up stockings this time, and no knickers! She’d been naked under the skirt, the slut. The black bra was unclipped and discarded, and she rubbed her breasts and shook them at him, saying something. He laughed and beckoned her.

The woman climbed onto the bed and knelt astride his head, holding onto the bedhead, displaying her pussy to her son. He wormed his finger into her slit and pulled out a black cord. I felt a warm gush in my knickers as he extracted a wad of black material from her puss - her knickers; she must have pushed them inside on her way home! God, they would be soaked in her sex juices. I heard them laughing as Will stuffed them into his mouth and chewed. His cock twitched rhythmically.

Jane turned round and lay on top of the lad, wriggling her crotch over his face. She closed her mouth around the head of his cock and massaged his balls in her hand. This was a 69, I recognized. He would be eating her cunt while she sucked his cock. I realised that my hand was inside my knickers, already slippery. They sucked for quite a long time, and once Jane took his cock out of her mouth and rested her head on his hip while she climaxed, her body shaking and twitching. As far as I could tell, Will didn’t come.

Then she got onto all fours and shuffled round so that her crotch was over his hips. I could see, between her open thighs, that her puss was wet and pink and swollen. Will held his cock up and she sank down onto it - I could see her lips sliding around the great purple head, and slowly working their way down the shaft. She rose and fell on him, slowly at first, then faster and rougher, slamming down onto his hips, impaling herself on the great column. Her lips dragged along the shaft on each upstroke, thin and stretched. It was more explicit than many porn clips I had seen.

Soon Will climaxed, noisily, while his mother urged him on with rough cries. I could see her hips rotating, her muscles milking all his spunk. His hands gripped her hips hard enough to leave white marks. When all had subsided she slowly rose off him, her lips reluctant to let go of his cock. It was still fat and slapped wetly against his stomach. Her cunt lips were loose and gaping. They both craned to look as a dribble of whiteness fell from her cavity and landed on his balls. I heard them both laughing. More globs of spunk trickled from her. Jane worked her way up his body, leaving a trail of gobbets on his stomach and chest. Then she shuffled back, lowered her head and stuck her arse in the air - god how her cunt gaped! - and proceeded to lick up every drop of cum from his body.

I climaxed for the second time, knees buckling, but couldn’t stop watching. She kissed him deeply, presumably with cum still in her mouth, while her big dark hole still dripped. Will’s hands stroked her bum and his fingers teased her anus and lips. I saw that his cock was hardening again, and I knew that another shag was inevitable. His mother gave it a couple of big sucks for luck (I could see her cheeks hollowing), then she perched on all fours, knees on the edge of the bed, cunt pointing directly at the door where I was watching. Will scrambled up behind her, his great cock waving. I heard her cry - ‘nnnghhh!’ - as he plumbed her innards.

Slurp, squish, slurp, they went as he fucked her from behind like a piledriver. Jane was juicing like a fountain because I could see drops landing on the carpet. Will rammed into her so fiercely that I couldn’t see how it couldn’t be hurting her. His buttocks clenched and all the muscles in his back stood out. But he didn’t have the stamina of my dad, because it wasn’t more than ten minutes before his back arched and he stopped pounding and pumped another load deep inside his mother - I could see the tendons in his thighs go rigid.

After he’d pulled out and collapsed on the bed, Jane stayed in her position. Her cunt gaped even more. Another trickle of whiteness overflowed onto the carpet. It was too much for me.

About 9 that evening, I was in my room trying to get through some homework. I heard Jane and my dad coming upstairs. They went into the bedroom and soon the noises began. It was not 5 hours since she had been shagging her own son. I resisted for a bit then took up position in the closet. They were doing it doggy fashion, both naked - Jane had even taken her stockings off. I wondered what was going through her mind while my dad was pumping into her already-lubricated cunt. They kept it up for ages.

In the morning they had a lie-in and shagged again, while I watched. No wonder she’d kept her figure, all the exercise she got. In fact they spent most of the weekend in bed, shagging or sleeping. I was in the kitchen when Jane emerged, in her dressing gown, looking mussed and smoky-eyed. She seemed to be walking a bit gingerly, I thought - maybe her cunt was getting sore.

‘Hiya, my love,’ she said, giving me a wet kiss. ‘Sorry I’m neglecting you. Just came down for some sustenance.’ She put the kettle on. ‘Thank god for Viagra, eh?’ She winked at me, and I blushed. She made tea and toast and disappeared upstairs again. I didn’t bother to watch - it was getting boring by now.

Later, Dad must have been asleep and Jane was pottering around, still in her dressing gown. Will was there too, watching TV. She plonked herself down beside him and he put his arm around her shoulders, and they conversed in whispers. Soon they got up and went upstairs. I followed and peeped. In his bedroom, she was kneeling in front of him with his cock in her mouth, giving him a slow and luxurious blow-job. Will’s eyes were closed in bliss. Her lips slid from the tip of his cock right down to the base, she must have got it halfway down her throat. Every so often she would remove her mouth and squeeze a drop of clear fluid from the end onto her tongue. She held the head in her mouth and sucked hard - I could see her cheeks hollowing. Her fist stroked the long shaft.

Jane said something to her son, and he nodded. He leaned back against the desk and arched his back, thrusting his hips forward, looking down at her. She pulled back a bit and wanked him fast, her mouth wide open. Will groaned as if in pain. At a range of six inches his spunk blasted into her mouth and over her nose and eyes, huge white ropes of it, six, seven, eight times. Then his mum leaned forward and closed her mouth over his cock. His body twitched as she presumably sucked out the remains of his cum.

She released his now limp cock and grinned up at him through a mask of sperm. Despite a weekend of shagging my Dad, she had still found time to service her son’s needs too - what a woman.

I lay on my bed and massaged my hot wet pussy, wondering what it felt like to have a boy ejaculate into my mouth and over my face.

I don’t want you to get the impression that I spent all my time watching my family members having sex. Most of the time I was busy with school and friends. The sex was just a background. Maybe Jane’s sexual appetite was normal at her age.

Once, when she was out, I tried dressing up in her work outfit, right down to the black bra and tangas and hold-up stockings. The elastic felt a bit tight around my thighs. I examined myself critically in the mirror. I did look a bit tarty. I lifted the skirt to reveal my stocking tops and panties. It felt quite sexy. I wondered how Dad and Will would react if they saw me. I pulled the panties between my pussy lips and masturbated. The material quickly became soaked. I leaned against the wall with one hand and masturbated with the other, watching myself in the mirror. I came, with wobbly knees. I put the wet panties in the linen bin - Jane wouldn’t notice an extra pair.

A week or so later things got more interesting. I came home early, and just stopped myself walking in on Jane and Will in the kitchen. I stood in the doorway, silently, taking it all in. Will was naked, his cock firmly erect. Jane wore stockings, heels, and a black bra which seemed to have holes cut out for her nipples to stick through. I couldn’t see well, as she was facing away from me, but she seemed to have clothes pegs attached to her nipples! She was leaning on the worktop, legs straight and wide apart, her bum thrust backward. Her son was behind her pushing what looked like a cucumber in and out of her cunt. It was long and green and quite a lot of it was going inside her each time. Jane was doing her usual pre-orgasmic moaning.

Eventually she said something and he withdrew the object - it was indeed a cucumber. Jane’s cunt gaped and her lips looked big and swollen. Will knelt behind her and started to lick her puss. He buried his face between her buttocks and it looked to me very like he was sticking his tongue right into his mum’s arsehole - aargh! Jane pushed back at him and chuckled throatily. Then he stood up and took a little bottle of something from the table, and squeezed a liquid out onto his fingers. He pushed one then two fingers right into her arsehole, twisting them round gently and then more roughly. His mother purred with delight. He got his fingers right inside, up to the knuckles, and pumped them in and out. I heard her murmuring ‘yes, that’s it, fuck it, fuck my arse.’

Her son now squeezed some more liquid onto his cock and smoothed it all over. I began to tremble at the thought of what was going to happen. He stood behind her and held his cock - it seemed ultra-stiff - against her arsehole and pushed. Jane writhed a bit. His cock was a lot bigger than his fingers! But it went in! Jane made throaty noises as the huge shaft disappeared slowly into her arsehole. When it was all in he rested for a while, then gripped her hips and started to thrust. I had a perfect view as he slid in and out, the full length on each stroke. God, what must it feel like for her?

Obviously enjoyable, because she was making all the right noises. So was he, grunting and puffing. His balls had shrunk to a tight little knot, and his back was sweaty. He shouted something and his bum clenched. I imagined all his spunk firing deep inside Jane’s arse. She urged him on. I counted twenty distinct spasms until his orgasm subsided and he stood, panting hard, still buried deep in her.

After a while he withdrew and stood back. Jane’s arsehole was big and dark, as was her cunt. She chuckled and said ‘here it comes’. There was a loud bubbling, farting noise and whiteness gushed from her arsehole and ran down over her cunt and dripped onto the floor. They both laughed. Jane wiggled her bum and another gush of spunk and air followed. He slapped her buttocks playfully.

My stepmum stood up and turned round - I ducked behind the door quickly. When I next peeped out she was perched on the corner of the worktop, her heels on the edges, her thighs spread obscenely. Will was kneeling on the floor in front of her. Yes, she really did have clothes pegs on her nipples! She held her cunt lips apart and he lapped at her gaping hole. Once fixed in position, she leaned back on her arms and closed her eyes and let her head fall backwards, so I felt able to watch properly.

Will ate her cunt eagerly and noisily and it wasn’t long before his mum was close to orgasm. He had his hands on her bum so that she couldn’t back away - not that she seemed to want to. Every so often he would reach up and twiddle the clothes pegs. She sounded like she was having trouble getting enough air. I could see her stomach and thigh muscles clenching. There was another wet fart as her arse released more of his spunk. Then she went completely rigid, and at that moment Will reached up and pulled the clothes pegs off her nipples.

Jane screamed, gasping for breath, as the orgasm hit her. Her whole body seemed to go into spasm. It was only Will’s mouth clamped firmly around her clitoris that stopped her collapsing onto the floor. I saw her nipples, huge and hard and angry red. When her climax eventually faded, I realised that my knickers were so wet that it had run down my thigh. I retreated upstairs to have the mother of all wanks - an appropriate phrase, I thought, in the circumstance.

It all came to a climax (!) the next day. I had snuck off school early again, hoping to see more antics, and I was not disappointed. They were in the kitchen again, Will naked, his mum in holey bra, stockings and heels. But there the similarity ended. Jane’s wrists were tied with rope to one of the old meat-hooks in the ceiling, so that her body was held vertical. I could see clothes pegs on her nipples again, and also this time a few on each of her cunt lips. Will was holding something against her pussy, and Jane was writhing and gasping. There was a buzzing noise - presumably a vibrator.

In the space of a few minutes Jane must have had 3 or 4 orgasms, or maybe they just all ran into one. Will leant against her, one hand on her bum to steady her, the other holding the vibrator against her clit. His cock bobbed against her stomach. They snogged wetly, breaking off to let her come noisily.

‘You want to be fucked?’ he murmured.

‘Yes, oh yes!’

‘Say it.’

‘Fuck me, oh please fuck me!’

‘You want to be fucked in the arse?’

‘Yes, fuck me in the arse! Oh please!’

He got the bottle of whatever it was and coated his cock in it while Jane whimpered with lust. Will went behind her and gripped her hips, bending his knees to get his cock in position. I saw her flinch as it went in, then her expression changed to one of ecstasy. He started to pump in and out, holding her body steady. I was so fascinated that I forgot to stay out of sight ...

Will’s eyes opened and he saw me. His face went from shock to a grin, not breaking his rhythm.

‘Hey, mum, we’ve got an audience!’

Jane’s eyes flew open, then her mouth. ‘Oh god! Jenny! Will! Stop!’

‘Bit late for that, ‘Will said breathlessly, continuing to pump in and out of his mother’s arse. ‘Hey Jenny, want to help?’

I was rooted to the spot. ‘Get the vibe,’ my step-brother ordered. ‘She needs to come again.’

Jane stared at me, making little mewling noises in time with the cock ramming into her arse. She nodded helplessly.

‘Go on, quickly,’ Will ordered. I picked up the vibrator and gingerly held it against my stepmum’s pussy, just at the top where her clitoris peeped out from between her swollen lips, adorned with clothes pegs. The effect was electric. Jane spasmed and writhed, but was prevented from moving too far by the cock which impaled her. Carefully I followed her movements, keeping the vibe over her clit. She howled and moaned. Will pumped relentlessly.

‘I’m gonna spunk!’ he shouted, and thrust deep into his mum. Jane shuddered and writhed. I could almost feel Will’s sperm blasting out into her innards.

When he slowed, I took the vibe away. Jane’s body, suspended from the hook, shook and quivered. Will withdrew and left the room, maybe to wash his cock, I thought.

‘You better untie me, love,’ Jane said weakly. I fumbled with the rope - it wasn’t tied very well - and helped her to sit down. Her skin was hot and damp with sweat. She sat carefully with legs wide apart, the clothes pegs clicking against the wood, and I heard a long, wet bubbly fart. She giggled.

‘I guess you know that your step-mother’s a nympho,’ she said. I knew the word, as an insult, but I would never have used it of her.

I sat next to her. There was another escape of fluids that lasted ages.

‘Oh god, he really filled me up that time. Can you take these pegs off, my love? My hands are all trembling.’

Carefully I eased the pegs off her cunt lips. The flesh was swollen and red and looked very sore. Then I took the ones off her nipples, fascinated by the way they swelled until they looked as if they would burst. Jane gave a low moan and cupped her breasts with her hands.

‘Does it hurt?’ I asked, husky-voiced.

‘No, well, yes, it does. Hurts quite a lot. But ... you’ll understand one day.’

She took a hand from her breast and put it between her legs. ‘I just love sex,’ she said, apologetically. ‘Always have. Can’t get enough of it, ever. I hope you don’t ... hate me.’ She looked so pathetic that I put my arm around her shoulders.

‘Of course not. I like you.’

‘I’m not a very good role model, am I?’ she giggled. ‘My own son.’

‘It’s OK,’ I said, hugging her.

‘I just get so horny. And so does he ... we can’t help it.’

‘How long ...’

‘Oh, a long time. I fancied him as soon as he passed puberty. And he had a thing for his old mum ... I gave him a present on his fifteenth birthday. After that we hardly stopped. He’s a very good lover, you know. Still comes too quickly the first couple of times, but then he can keep going for hours. You should try him, you know.’

‘Me?’ I squeaked, although in truth I had thought about it ever since Will moved in.

‘Yes, you!’ she patted my leg. ‘You’re a woman now, sexually. Don’t tell me you don’t get horny. Or maybe you’re already screwing.’

I shook my head.

‘What’s that? Not screwing? Or don’t get horny?’ she grinned.

I had to grin back. ‘Well, I do get horny ...’

There was another bubbly eruption from Jane’s arse. She chuckled. ‘I shouldn’t be encouraging you to fuck Will, should I? He might not want me so often.’

‘Will’s not interested in me. He barely notices me.’

‘He fancies the pants off you. He told me so.’

‘Oh my god.’

‘But he’s too much of a gentleman - thinks you’re too young. And I try to keep his sexual urges satisfied. But if I didn’t ... there’s no knowing what might happen.’

She stroked my leg. ‘Tell you what - Martin’s away tonight. So I’d normally slip into Will’s bed for a nighttime session. But if you took my place ... chances are he wouldn’t notice - until it was too late.’

‘But he ... he’s so big!’

‘Don’t worry, I’ll be on hand to make sure you don’t get hurt. What do you say, girl? Up for it?’
