Mom's Special Medical Condition

My arm wraps around her body as I slide up behind her, we are both lying in bed naked, the early morning sun peaking through her bedroom window bathing the room in it's soft glow. She stirs as I cup her breast, gently massaging it as I press my cock between her ass cheeks, slowly grinding against her as I kiss her neck and shoulder.

Sliding my hand down her body my fingers glide through the neatly trimmed bush on her mound, my finger coming to rest against her clit. Pressing my cock harder against her I nibble on the lobe of her ear, my finger rubbing her clit in a slow circular motion.

She makes soft purring noises as my middle finger runs down between her pussy lips to her pussy, running around the rim through the juices flowing from it. My middle finger slides in and out of her pussy, only as deep as the first knuckle at first but slowly getting deeper until it full length slides back and forward inside her.

Moving her ass slightly away from my cock she moves her arm, I feel a fingernail run along my cock before her long slender fingers wrap around my shaft.

Her moans grow louder as my finger moves faster, her grip on my cock growing firmer as she jerks it. She freezes momentarily, her body going rigid, her hand squeezing my cock harder, then with a squeal she comes, her body trembling with an orgasm.

Still with a firm grip of my cock she lifts her leg placing it on top of mine, moving my cock she rubs the head over her pussy lips, pressing it against herself as she guides it into her pussy.

She starts rocking her body, my cock sliding back and forward, moving my body closer to hers my cock sinks deeper into her pussy.

Our bodies work in unison as we fuck, moving as one at a frantic pace, our desire, passion increasing by the second until with a grunt I come. Pressing myself firmly against her body, my cock is buried as deep as possible in her pussy filling her with cum as she squeals, her pussy spasming around my throbbing cock with her orgasm.

"You better go Steve, your father will be home soon."

"Yes Mom," I say giving her a kiss before rolling out of bed.

Briefly I stare at her gorgeous naked body glistening with sweat in the early morning sun, glancing at the clock it's 6.15am Dad will be home about 6.30am, after one last glance at Mom I turn around moving to the bedroom door opening it.

As I lie on my bed I hear Dad getting home, walking down the hall as he goes to his bedroom. He's the nightshift manager working from 10pm to 6am Monday to Friday, it takes about 30 minutes for him to travel to and from work. He's being doing it for about the five years, prior to that he was on day shift Monday to Saturday, the move to night shift gave him a pay rise and a full weekend.

Staring up at the ceiling I smile as I think how lucky I am and how jealous my mates would be if they could see me now. I always got teased about being a Mommy's boy growing up everything I did was with Mom, Dad was always at work. As we grew older the teasing changed, they started teasing me about Mom being a hot milf and what they would do to her.

Actually what they dreamt of doing to her is what I'm doing now.

Mom is very attractive, at 41 she has the body and face of a 20 year old, she has short blonde hair, crystal blue eyes, a small button nose and full red lips. Her neck long and slender, breasts full and round with pink areolas and naturally perky nipples. She exercises every day doing aerobics and weights giving her a firm flat stomach and a well toned body, her ass a juicy firm peach drawing your eyes to it, her legs long and muscular. At six foot two she stands out in the crowd, her lily white complexion eye catching in the clothes she wears, it's only natural to be drawn to her and desire her.

My relationship with Mom changed on my 18th birthday, my actual birthday was on the Wednesday but with Dad in his new job we planned my birthday party for the Saturday night. I invited some school mates and Mom invited several of the neighbours, in all we had about 30 people attending.

Everyone was having fun on the night, a marquee was set up in the garden, Dad had organised caterers, music played and alcohol flowed. With so many guest we hired a porta loo, it was occupied when I wanted to pee so I decided to use the toilet inside. It was also occupied, it was then I decided to use the bathroom in Moms and Dads room, that was when my life changed.

Opening the door I was stunned by the sight that greeted me, Mom lay on the bed her dress bunched up around her waist, panties lying on the ground and tits bouncing around. Mr Johnstone from down the street was standing between her legs his cock buried in her pussy as he held her legs by the ankles in the air spread wide.

Mom saw me as soon as I opened the door, it took Mr Johnstone longer, long enough for me to see his cock pounding Mom's pussy. Once he realised I was there he froze with his cock buried deep in Mom's pussy, he was actually coming inside her as he stared at me. Pulling his cock out cum was still dripping from it as he looked at me, reaching down he pulled his pants up, bumping me as he rushed out the door pass me. Mom still lay on the bed, her legs spreads, cum dribbling from her pussy onto the bed, a look of shock and horror on her face.

I was speechless, turning around I left the room closing the door behind me, the bathroom was now free and I entered. Staring into the mirror I was filled by mixed emotions, I was angry at Mom, I was sad for Dad and I was aroused, my cock was rock hard.

Getting back to the party I was there in time to see Mr and Mrs Johnstone walking down the driveway leaving, Mrs Johnstone didn't appear too keen on the idea. For the rest of the night I avoided Mom and on Sunday I made a point on going our for the whole day and most of the night.

It was the following Tuesday night that Mom came to my room after Dad went to work.

'Steve we need to talk," she said.

"About what?" I said, I wasn't going to make this easy for her.

"You know, what you saw Saturday night."

"Nothing to talk about, you were being a slut cheating on Dad."

"Yes I was but I couldn't help it."

"Ah, Mr Johnstone forced himself on you did he."

"No, no never I wanted him to fuck me, I needed him to fuck me."

"Then why couldn't you help yourself Mom?"

"I have a condition, I need sex."

"We all want sex and you being married get sex from your husband, my father."

"I don't just want it Steve, I need it, medically I really, really need it," She paused letting that sink in before continuing, "I hate myself for it but your Dad is not enough and now he's working night it's even worst, that's why I need to be with other men."

"You saying Mr Johnstone wasn't the first?"

"No he wasn't, isn't."

I stared at her, tears ran down her cheeks, I didn't fully understand everything she had said but it was clear she's been cheating for awhile.

"Don't hate me Steve, I take pills to reduce my need for sex but they have other unpleasant side affects." She said as she took a bottle of pills from her dressing gown pocket. "I have to admit I do go off them occasionally, I know I shouldn't but I think that being with someone else is the lessor of the two evils."

I was speechless, for the second time in a week as I stared at my Mom I was speechless not only because of what she had said but because of what I saw. As Mom pulled the pills from her pocket it loosened the cord of her gown allowing the top to fall open exposing one of her breasts. Also while she sat on the bed the bottom of her gown had also opened as she moved around and gave me a glimpse of her pussy.

Mom became aware of me staring at her breast, she quickly pulled the gown up to cover it only to fully expose her pussy to me.

"Sorry Steve I... I didn't mean for you to see me like this," she said bursting into tears, her hand releasing her gown letting her breast once more fall out.

Feeling sorry for her I sat up and gave her a hug, at the same time the sheet came off my body to leave me just sitting in my boxers. As our hug broke my condition became obvious, it was like I had a large tent pole poking out the front of my boxers.

Mom stared at my boxers, she didn't try to cover herself up which only made me harder. There was a hunger in her eyes, her tongue ran over her lips as she stared at my boxers, her hand touched her breast brushing her nipple before it dropped between her legs.

I'm not sure she knew what she was doing, her focus was on my boxers and the cock underneath, the rest of the world including the rest of my body didn't exist at that moment. Mom's free hand reached down inside my boxers and pulled my cock out, cupping my balls she lowered her head taking me in her mouth.

She sucked my cock and fingered her pussy until I came, she sucked every drop of cum from balls without dribbling a drop. Without a word she stood up and left my room, my flaccid cock covered in saliva and cum rested on my stomach.

Mom returned the next night, this time she wasn't wearing a dressing gown or anything else, she just walked into my room and climbed in bed beside me.

"Mom you can't be here, it's not right."

"You didn't complain last night Steve."

"That was wrong, I... I couldn't control myself."

"Don't you think I'm sexy?"

"Of course you are but your my Mom, it's not fair on Dad you cheating on him."

"Isn't it better I'm with you rather than some random stranger?"

"It's no different, it's still cheating and it's wrong."

"How is it wrong, you are your fathers son so in a way I am with him when I'm with you."

"No it's still not right, you're my Mom."

"And that only makes it more special, most people don't understand or appreciate the special secret love a mother and son can share."

"But that's... that's incest."

"Only those that don't understand it call it incest, to the enlightened it's a magical way for a mother and son to show their deep love for each other."

I knew I was fighting a losing battle on two fronts, Mom wasn't going to take no for an answer and my hard cock showed my body had already surrendered to her.

Mom had also noticed that while my mouth said no my body said yes.

She had pushed the sheet backed when she climbed on the bed, her bare leg was touching mine, rubbing against me as she moved. As our conversation progressed she began running her finger over my chest, slowly working it down my body as my cock grew until her finger was tracing my shaft through my boxers.

She pushed the front of my boxers down grabbing hold of my cock, as she stared into my eyes she smiled at me while stroking my cock, I thought I was in for another blow job. Instead she was suddenly straddling my lap, as she held my cock she lowered herself onto me, her eyes never left mine. Putting a hand on the back of my head she pressed it against her breast as she bounced on my cock, she rode me until I came in her pussy. Mom then sucked me hard again as I ate her pussy before I fucked her doggy blowing another load deep into her pussy.

That was the beginning, for the first few weeks Mom came to my room a few nights each week when Dad was at work then things went to another level when Mom took me to her bed and I started spending the occasional night with her. Now when we are together at night it's always in Mom's bed.

Now you would think I have the perfect life, constant sex with a hot insatiable milf that will fuck me anyway and anywhere I want. It is I couldn't want more but I have more and I couldn't be happier.

It was about six weeks ago on a Saturday night or more correctly a Sunday morning. With Dad home on Saturday nights Mom is occupied with him meaning I'm free to go out on the town. On this Saturday night I got home after midnight, normally the house is quiet at this time of night but as I walked towards my bedroom I heard a noise, it was coming from my sister's room further down the hall.

Her bedroom door was slightly open, I stood outside it for a couple of minutes before entering. She was crying, she was sitting on the side of her bed rocking back and forward as she hugged a stuffed toy.

"Bec what's wrong?" I asked as I sat beside her wrapping my arm around her shoulder.

"I'm going to be a slut."

"Sorry, what... you're going to be a slut."

"Yes."

"What do you mean, you don't have to be anything you don't want to be."

"I... I have no choice, it's my destiny."

"Destiny!"

"Destiny, fate, doom."

"All sounds very dark, but I don't understand."

"I have a medical condition that will end my life."

"What, you're dying!!!"

"Not literally but I might as well be."

"Bec just tell me in plain english what you are talking about."

"I have a rare medical condition that'll make me a sexaholic that will never be faithful to one person."

As I sat there I saw an opportunity, I didn't know if Mom's condition was hereditary or not but if Bec is like Mom wanting, needing sex I could be of service.

"How do you know?"

"Mom told me, I wasn't feeling well and was telling Mom about it and she told me it was a family condition."

"Is there a cure?" I asked pretending I knew nothing about what she was talking about.

"No cure just drugs that could suppress it or something."

"Well there's hope then."

"Not really, Mom says the drugs have horrible side effects."

"What's the other options?"

"There's only one, sex."

Not an unpleasant thought, Bec is three years younger than me at 20 and like Mom drop dead gorgeous. She has long blonde hair which reaches down to her ass, she is tall at just over six foot with a firm petite body. Her breasts are small and perky always poking out the front of her tops, her hips narrow, she loves wearing tight clothes which show off her small firm ass, and her legs are long and slender.

"Let me help you," I say placing my hand on her thigh.

Looking at me she asks "How?"

I didn't answer her verbally instead I leant forward kissing her, pushing her back down on the bed as we kissed. She didn't resist, she returned my kiss with passion as she wrapped her arms around my back.

Bec was wearing a nightie as she sat on the bed and only a nightie I discovered when I slide my hand along her leg and under nightie to her bare pussy, a soft bare pussy with fine delicate lips. I unbuttoned her nightie as she laid on the bed, I moved my mouth to her sweet little breasts, licking and sucking her nipples.

I fucked Bec that night, actually twice to be honest without the slightest regret or feeling of guilt. I suppose it may have been due to the fact that I have been fucking my mother for years that the concept of incest being wrong never crossed my mind. If sex with your mother is special then sex with your sister must also be special. The fact that Bec never hesitated or resisted from the moment I kissed her only helped to make it feel right.

Saturday and Sunday nights became Bec and my night, we still went out on Saturday nights to keep things looking as normal as possible. I wasn't sure how Mom might react if she found out we were fucking, though having Dad home on weekends helped in this regard but it was becoming harder to keep me and Mom a secret from Bec.

I managed to convince Bec to keep our relationship special we should only be with each other sexually on weekends, that she should let her desires build during the week and it will ultimately increase her pleasures on the weekend,

We made Saturday nights our special night.

We would both go out with our friends separately meeting up somewhere during the night.

It's exciting, thrilling to be fooling around when out, the risk of getting caught adding to the excitement and pleasure of our sex. The joy of sneaking off to the toilet, into a cubicle, fucking each other as people come and go, or leaving the club meeting in a dark alley, Bec wrapping her legs around my waists as I hold her against the wall while she bounces on my cock or bending her over fucking her from behind as she leans against a wall. Always with the same result of us returning to join our friends knowing what we just did and that Bec has a pussy full of my cum which is slowly dribbling down her leg.

When we can we also pretend to be strangers meeting each other for the first time, flirting and fooling around with each other, always ending with sex where ever we are.

Once we get home we are like wild animals, luckily Mom and Dad are always in bed as we can barely keep our clothes on or our hands off each other. As soon as we get into a bedroom, generally mine as it's the closest to the front door, we are naked making out.

Bec's waxes her pussy, she gets it done every Friday which means as well as being super smooth it's also super sensitive for our weekend together. She loves having her pussy eaten, as soon as I get her into my room I go down on her, kissing and licking her pussy, slipping my tongue between her lips, lapping up her juices as they pour from her pussy. She grabs my head pressing it firmly against her pussy as she rubs her clit with the other hand, holding it there until she's ready to squirt then pulling it back she squirts all over my face before pushing me down onto her pussy again.

Releasing her grip I kiss my way up along Bec's body stopping at her breast, my mouth moving back and forward between her hard nipples. As I suck her nipples she spreads her legs wider offering herself to my cock, reaching down I take hold of my cock rubbing the tip against her pussy lips, slowly pressing it against them, forcing them apart as I slide into her pussy.

Bec wraps her legs around my back as I fuck her, holding me firmly as my cock moves back and forward inside her. Lifting my mouth off her breasts I kiss my way up to her mouth, our tongues wrestling as our mouths touch, our bodies wrapped together in a passionate embrace.

Breaking our embrace I roll over onto my back, my signal for her to mount me, for several minutes she kisses and nibbles my nipples as her fingers wrap around my cock sliding up and down.

Bec straddles my lap, her fingernails scratching my chest as she rides my cock, her pussy squeezing around me tightly as she bounces up and down. Her head tilted back, hair touching my legs. She smiles as her nails dig into my chest, her body trembling as she presses down on my lap swallowing my whole cock in her spasming pussy.

Climbing up Bec turns around to ride me reverse cowgirl, it's a lovely view watching her sweet ass. It isn't long until I feel that familiar swelling of my cock and that tingling sensation the second before I come.

Hoping off my cock Bec takes me in her mouth, cum dribbling from her pussy onto the bed as she licks and sucks my cock.

For a little while we lie side by side kissing, our hands wandering over each others bodies until my cock is fully aroused again.

Now it's not only time to enjoy the view of Bec's ass but it's also time to enjoy fucking her ass. Bec gets on her hands and legs, her head resting on the bed as she sticks her ass in the air offering it to me.

Picking up a tube of lube I squeeze some over her asshole and on my cock, for the next few minutes I spread the lube around the rim of her ass and inside while at the same time coating my cock with it. As I do the lubing Bec fingers herself, rubbing her clit and sliding fingers in and out of her pussy, as her excitement grows so does the speed of her hand and finger movement.

Even well lubed her asshole is tight, she groans as I push my cock into her, stretching her little hole. Her body is perfection and this sweet little asshole represents the icing on the cake, the ultimate pleasure as I fuck her until I come.

The following week I spent Monday, Tuesday and Thursday night in Mom's bed, on Saturday night I went out as normal meeting up with Bec around 9pm. Our friends aren't with us tonight which would normally mean extra fun for us but tonight Bec was a bit off. She wasn't as flirty as normal, even wanting to go home early, I convinced her to stay a while longer.

We're sitting at a table having a drink I put my hand on her thigh moving it under her dress, she automatically opens her legs. As usual she's not wearing panties, I rub my fingers around and over her pussy lips before sliding one then a second into her pussy. I watch her nipples go hard as I finger her, she bites her lip to suppress her moans, her hands making fists, fingernails digging into her palms. With a slight squeak she comes, taking my fingers from her pussy I place them in my mouth sucking her juices of them.

This time there's no changing her mind and I find myself getting home just after 11pm, as usual the house is empty but there's no frantic energy from Bec, no urgency in rushing to my bedroom. Instead she stands in the hallway kissing me, taking my hand she walks pass my bedroom to her room.

Once again she kisses me as she opens the door, turning me around, pushing me backwards in her bedroom. She continues kissing me as she starts undressing me only stopping to remove the last of my clothes and her own. Standing naked in the middle of the room I look at her body, my cock growing harder by the second as is my hunger and desire to have her.

"I have a surprise for you Steve," Bec says stepping closer to me.

"Hmm I like surprises," I say just as I feel an arm wrap round my waist and fingers wrap round my cock.

Spinning around I see Mom standing in front of me.

Bec steps pass me moving up to Mom kissing her passionately, turning to me she kisses me before kissing Mom again.

Mom has kept hold of my cock and now pulls me towards the bed, reaching it she pushes me down on to it. Taking her hand off my cock she places it on the middle of my chest pushing me backwards so I'm lying on the bed, as she does she climbs over my body positioning herself over my face.

As Mom lowers her pussy to my mouth Bec fingers wrap around my balls and her mouth swallows my cock.

Mom grabs the back of my head pulling it up, pressing my face firmly against her pussy as she grinds it against me. Mom isn't a squirter like Bec but she still gets extremely wet and as she rubs her pussy over my face I'm getting lathered in her juices. Meanwhile Bec's fingers squeeze and juggle my balls as she slurps on my cock, I can feel her saliva running down the shaft onto my balls.

Climbing off my face Mom gets on the floor, pushing my legs further apart she moves in beside Bec. I lift myself up on my elbows to watch them as they use their mouths and tongues to play with my cock and balls.

Mom grips my balls and base of my shaft squeezing them as Bec and her run their tongues up and down my shaft, around my nob with each time they reach the tip they kiss each other before returning their tongues to my cock.

Mom sucks on my balls first one at a time then my whole ball sac as two fingers and her thumb massage the base of my shaft. Bec is sucking on the nob of my cock, her tongue rubbing against it.

I'm not sure how long they have been playing with my cock but I do know I'm not going to last much longer. They know it also as they move their heads over my cock kissing as Mom wraps her fingers around my shaft and starts jerking me off. It only takes a minute or so before streams of cum shoot up hitting their faces, Mom keeps pumping my cock as cum pours out flowing down my shaft onto her fingers.

Bec and Mom lick the cum off my cock, then Mom's fingers before turning to each other faces and licking my cum off.

With me out of action cock wise for a little while they climb on the bed getting into the 69 position with Bec on top. I lie beside them sucking on Mom's breast while I play with Bec's breast or rub Mom's clit.

With a hard cock I move behind Bec's ass, Mom is feasting on her pussy leaving her sweet little asshole for me. Leaning forward I run my tongue over her ass making her body tremble as I touch her, my tongue runs around the rim of her ass making her wet with my saliva, spreading her cheeks I slide my tongue in and out of her hole.

Dribbling saliva over her asshole I massage it inside with my middle finger, rubbing my finger around inside her as I slide it deep into her ass. Spitting into the palm of my hand I rub saliva around the nob of my cock as I finger Bec's ass.

Bec is no longer eating Mom's pussy, she moans constantly as I slide back and forward in her ass while Mom sucks and licks on her pussy and clit. Mom has already received one squirting facial and by the sound of it she's about to receive her second.

As Bec squirts her ass squeezes tighter around my moving cock pushing me over the edge, with a grunt I come in her ass, pushing my cock in as deep as I can I fill her asshole with cum.

Bec climbs off Mom lying on the bed beside her facedown, panting heavily, Mom rolls over onto her stomach taking first my cock in her mouth slurping and sucking on it. She then moves to Bec's ass spreading her cheeks licking and sucking my cum from her ass.

As Mom eats her ass Bec turns her attention to my cock pulling it towards her mouth, her tongue running around the nob before she closes her lips over it and sucking.

I'm on my knees in front of Bec as she sucks the nob of my cock and plays with my balls, she lies on her stomach with Mom's head nestled between her legs as she licks and sucks Bec's ass and pussy.

Hard again I turn my attention to Mom, she rolls onto her back spreading her legs, jizz dribbles from her wet pussy, I run my finger along it scooping it up feeding the first finger load to Bec before sucking the second finger load myself. Moving forward I rub the nob of my cock against her lips and clit making Mom moan, leaning forward I rub the length of my cock along her pussy while I suck on her nipples.

Bec has been watching me or more accurately watching my cock sliding between Mom's pussy lips as I lean over her, reaching out she rubs Mom clit and the nob of my cock when it appears.

Sitting up I take hold of my cock once more rubbing the nob against Mom's pussy, Bec moves beside me taking my cock from my hand. Leaning over she sucks the nob before rubbing it against Mom's pussy then sucking it again, she repeats this several times as Mom starts squirming begging for my cock to fuck her.

Bec isn't finish playing with my cock or Mom yet, she starts pushing my cock into Mom's pussy only to pull it out sucking it before shoving it back in, while at the same time she rubs Mom clit. All Bec's playing has given Mom an orgasm and holding my cock to one side Bec licks the jizz from Mom's pussy before kissing me as she shoves my cock into Mom's pussy releasing her grip.

Mom has two more orgasms as I fuck her and Bec plays with her clit and nipples before I come in her pussy. Bec pulls my cock out finishing me off in her mouth before diving on Mom's pussy cleaning the cum from it.

Exhausted we collapse on the bed kissing, Mom leaves shortly after saying Dad will be home soon.

Bec explains to me that Mom texted her when we were out saying Dad got called into work and wouldn't be home until early next morning, that was why she was in a hurry to leave earlier. I also found later that Mom and Bec have been fucking for the pass 12 months or so when Mom first told her about the medical condition. It's was Mom's idea for Bec to fuck me telling her it would help as her condition worsened and now threesomes were the next step in managing it.

I often wonder how real this condition is but the constant amazing sex makes it seem irrelevant and I'm more than happy to be the cure to what ails them.
