A Black Mark Against the Family
by Isabella

I'm not sure if I've mentioned it before but we, my husband James, daughters Amy, eight, Laura, six and son William, four, all live in one of James's mother's houses, when James was working we were paying his mother rent, around a thousand pounds a month, but the house was a huge six bedroom home with large garden and a swimming pool, so it was worth it. When James was made redundant, his mother started to put seventy percent of the rent we paid into an off-shore bank account for us to use after the redundancy ran out and, if James was still unemployed and we had to rely on unemployment, that bank account would give us a little extra comfort.

'There is no such thing as a free lunch!' After almost a year of unemployment, James's redundancy money running out, I suddenly discovered that we had a cousin that had been, well, not exactly hidden, but never spoken of. James's aunty, on his mother's side of the family had a son, Mark, he was just sixteen years old, his nick name in the family was 'Black Mark' and that wasn't a reflection on his ethnicity, but his behaviour.

Mark was in trouble, nothing unusual in that from what I heard, his family lived in Manchester, there was an incident with a girl, a gun and some stolen goods, no one was saying just how involved Mark was in the whole thing but the upshot was, the girls family were out for blood, Marks blood, the police wanted to lock him up and the owner of the stolen goods was after him too. June approached me, "Mark is family, you live in a family house, you have the room and you are at home all day to keep him out of mischief!"

I knew it wasn't a request, I knew that I could refuse to look after Mark but I also knew that June had several empty three bedroomed cottages in the village that were only worth a quarter of the price of the huge place we lived in, I also knew that June wasn't above selling up our house from under us and being forced to move us into smaller accommodation.

When Mark turned up he wasn't at all what I had expected, I had imagined him to be five foot nothing tall and skinny, like most of the boys I had known when I was sixteen, Mark was no skinny kid, he was over six foot tall, he was something of a body builder too, he seemed to have a wall of chest but a pinch of a waist opening out to quite wide hips for a boy, the width wasn't pelvis it was muscular thighs.

The first day was uneventful, the second was too, on the third day I woke up at six o'clock in the morning, which was a lie in for me, William often woke me at five am. Mark and Amy were already in the living room, I could hear Mark reciting a nursery rhyme, I thought it was sweet of Mark to be entertaining Amy with a nursery rhyme, even though at eight, Amy would have easily been able to recite the rhyme to Mark.

"Ride a cock horse to Banbury cross!" was being repeated over and over again, when I got into the room my thoughts of how kind and generous Mark was being was misguided, mark was sitting on the middle seat of the sofa, he was dressed in just his boxer shorts, Amy was in her nighty, she was sitting on his lap, facing him, with one foot either side of Mark's hips. As he was reciting the rhyme he was bouncing Amy up and down as if she were riding a horse, only the horse's saddle had been Mark's abdomen.

I was shocked to say the least, I didn't dare check but Amy often slept with no panties on under her nighty, I cleared my throat, I was ignored and the bouncing kept on going. "Amy, I think you should go and shower and get ready for school!" Amy reluctantly slid backwards down Mark's lap. As she slipped onto the floor both hers and my eyes, were fixed on the front of Mark's boxers, a huge erection was inflating the front and he didn't bother to try and hide it in any way.

I didn't make anything of it, I couldn't speak anyway, there was a lump in my throat, not quite as big as the lump in young Mark's pants though. My head was in a spin for the rest of the day, I didn't have what could be called a conventional marriage, I had never seen my husband naked, I had never even seen him in just his underpants before, I had no idea how a lump in James's pants would compare with the lump that was burned into my memory from watching my daughter climb off of it but I doubted that James would have made the same impression on the front of his pants.

That night I asked Mark if he needed his pyjamas washing, "Oh aunty Issy, you're so old-fashioned, I don't wear anything in bed, not even my underpants!" I was a little shocked by that revelation, I had never slept naked, in fact, I could have gone out shopping in what I wore to bed, neck to toe flannelette nighty, bra and knickers.

I spent the rest of the evening thinking about Mark, in my mind he was a sixteen year old boy, in reality Mark was as tall as my husband, in the main he was as mature as my husband and I was certain that he had, at only sixteen, had far more life experiences. Mainly because Mark was a city boy, exposed to life in the raw on the streets of Manchester, James had never lived outside of Northamptonshire, even when at university, James had been cosseted in the seminary and even when he switched from theology to business studies he was still in the same closed environment.

I had a very disturbed night's sleep, unusual for me because I usually slept well, the image of Mark's erection through his underpants, the image of Amy bouncing up and down on Mark's lap, her private parts so close, possibly even rubbing against......... then the image of Mark naked just three feet away from me, the other side of the wall, and then I was awake, shivering and sweating at the same time, the dream repeating over and over again in my mind.

Over the next few days I tried to keep Mark and Amy apart, I woke at the slightest sound and checked to see that Amy was still in her bed alone, I also watched closely as Mark flirted heavily with Amy whenever James was out, Mark didn't seem to care if I saw him making a play for Amy though.

It was four days later when I woke at four o'clock in the morning, there had been a gasp or a giggle, one or the other, or something else, it was coming from the living room, I got out of bed and checked Amy's bedroom, her bed was empty, I tip-toed down the stairs, Amy was sitting across Mark's knee, he was once again wearing just his underpants, Amy was in her nighty again, this time I didn't need to wonder if she was wearing knickers under her nighty or not, Mark's hand was firmly planted on her bare bottom, her nighty was 'hiked up' at the back, they were engaged in a passionate kiss, so engrossed that they failed to hear me open the door, I pulled Amy off of Marks knee just as his hand was working around her bottom to come at her little pussy from behind and below, "Back to bed young lady!" I said sternly.

Mark was about to follow her up when I stopped him, I closed the door and pushed him down on the sofa again, well, I tried to push him down on the sofa, he was solidly built and I just bounced off of his bare chest. I had practiced the speech in my head several times, the 'you're twice her age', the 'She's too young', the 'She doesn't understand that you are just playing with her'. Mark stopped me mid flow, "There are only five girls within a five mile radius, two are older than Amy, but only by two years but Amy is far more mature than either of them, anyway, Amy is gagging for it, she has been trying to get me to go into her bedroom when you guys are sleeping but every time I've tried you have been up like a shot. I'm going mad; all I'm doing is watching TV and masturbating ten times a day. It's not my fault that I've been banished down here two hundred miles away from my bitches!"

Mark brushed me aside and stamped his feet on every tread of the stairs as he went up. At breakfast there were a lot of blushes on my face and Amy's face too, Mark looked unconcerned, he was totally happy that he had been trying to seduce my young daughter. As soon as Amy and Laura left for school I phoned James's mother, Mark was hovering so that he could eves-drop on my conversation with his grandmother. I explained what I had found a few hours earlier and that I needed her to find somewhere else to house her grandson. "You're our only option unfortunately; he has to stop with you for at least two more weeks, until his case comes before the magistrate. I'll send Ron over to have a word, I'm sure there will be no problem after!"

I was very disappointed, even more so when Mark said, "I'll not bother packing my bag just yet!" As he left the room. When Ron turned up an hour later, he knocked the back door and walked in the kitchen where I met him, "Mark's up in his room!" "I'm not here to talk to Mark; I'm here to talk to you!" Now I was confused, I was even more confused when he dropped a packet of ten condoms on the table. "Mark has been sexually active with a large number of girls for two years; apparently he has a reputation as a bit of a stud in Manchester. Anyway, we're, sorry, you're stuck with him, he's not like James, he can't go for five years without sex and keep his sanity, he hasn't got James's religious beliefs to sustain him!"

I was shocked, I knew that James's parents knew that James and I didn't 'communicate' as husband and wife since James made me pregnant with William, June had to countersign the contract between James and I that gave me ownership of her house if James ever tried to rape me again, the house was after all his mother's property, but it had never been mentioned since and never by Ron, who had always been very, 'very' friendly towards me since that date.

"I'm sure that James has been a good husband but unfortunately I wasn't around much during his formative years and his mother has ruined him totally as a man, but, I'm sure that young Mark would open your eyes and make your toes curl from what I've heard, all you have to do is let yourself go and let yourself have a little fun, Mark will get the hormone problem out of his system, Amy will be safe and you might get a little out of it too!"

I was shocked, James's father was suggesting that I had sex with someone other than James, and a family member at that, then, when I thought that I was as shocked as it was possible to get, he shocked me a little bit more, "And when Mark has used all of those on you, ring me and I'll bring another box over and use them on you myself!"

Ron left me in a state of shock, shock and something else, I was actually shivering with excitement, I watched as Ron walked past the kitchen window, he had dropped his bombshell and walked out, not his usual kiss on the cheek like usual when he left, he kissed me on the lips before he walked out. Mark hadn't been up stairs in his bedroom as I thought; he had sneaked down to the living room, so that he could listen in on his grandfather's talk to me.

Mark was in the kitchen before Ron started his car engine, Mark swaggered past me, he picked up the box of condoms and held them right in front of my face, he pulled the cellophane tab to rip the outer packet off and then flipped the lid off of the box. He then took out one of the silver wrapped prophylactics, he dropped the box on the table and passed the wrapped condom between the fingers of his left hand, like a magician doing finger exercises.

I was mesmerised, still very much off balance from Ron's suggestion and parting kiss, Mark moved his left hand right in front of my face, the condom almost touching my nose as it ran through his fingers, then, almost without my feeling it, he used his right hand to flick the hem of my dress up a little, easing his right hand down between my thighs, I didn't want to open them for him but my eyes and my mind were totally fixed on his left hand and the rotating condom as it flashed past my eyes.

I had no idea how he managed it but suddenly there was a sharp pain as Mark forced the gusset of my cotton panties up into my vagina and two of his fingers along with it. Mark moved his hand out of the way and lowered his face down to mine, his lips clashed with mine as his fingers stabbed harder up into my body, pushing the material up ever higher. His left hand pressed against the back of my neck, pressing the condom, still in its foil against my skin, then he seemed to lift me of the seat with just his lips and left hand, well both hands, the pain between my legs was intense.

I had no idea just how strong Mark was, I was trying to touch the floor with the tips of my toes as he forced his tongue into my mouth and the fingers of his right hand were digging into my body hard, almost all of my body weight was resting on my clitoris, trapped as it was against the pads of his fingers on his palms. I was starting to get a very strange feeling, I was getting very breathless as Mark began to shake me from side to side, I was getting breathless, if I had been with James at that point he would have stopped whatever it was he was doing to cause my pleasure, after all, only a whore would enjoy sex and it was a husband's duty not to turn his wife into a whore.

I felt hot sweaty skin starting to press against my pussy as the shaking was slowly moving the gusset of my panties to one side, then bare skin inside of my vagina too as Mark's fingers freed themselves from the safe cover of cotton, I sank a little further down his fingers, he was searching around inside of my body, pressing around on the roof of my vagina, I gasped as a sudden wave of pleasure flooded my body, I had never felt anything that deep inside of me during 'intimate time', another gasp as I started to dissolve into an orgasm, the first ever at someone else's hand and the first one from deep massage inside of my pussy.

I felt Mark's mouth change as it pressed against my mouth, it changed from tight concentration as he kissed me to wide smiling as he realised that he had achieved his goal of making hard contact with two different erogenous zones at the same time. Mark changed his hand action too, from side to side to back and forth, slowly at first, then building up in speed and as the speed built the movement of his hand reduced until the point where there was almost no movement at all, his hand just seemed to vibrate, causing intense pleasure through both erogenous zones.

I don't know how it came about but somehow my arms were around Mark's neck and I was now kissing him rather than him kissing me. It had been over four years since I had last been intimate with anyone, well, my husband actually, he was the only man I had ever been intimate with in my life, well, up to this point, now Mark was being very intimate with me, far more than my husband had ever been and he had given me three children, three children but no orgasm, I had lost count of the number of times that I had orgasmed just on Mark's fingers in just a few minutes.

And as suddenly as it had begun, Mark's fingers slipped out of my cunt and he dipped his head forward and lowered me to the ground. I was gasping for air still, I thought that I was going to have a heart attack because my heart was beating so fast, Mark dropped the condom that he had been holding in his left hand all that time onto the table top and slipped the box with nine condoms into his pocket and walked out of the room. I had collapsed on the floor as soon as Mark had let go of his hold on me and it took me so long to recover that James and the kids almost walked in and found me still there on the floor where Mark had dropped me.

I was disgusted to find that the floor was soaking wet, I had hoped that it was sweat or some other innocent liquid but I knew that it had all come from inside my own body, via my vagina, either pee or some other clear liquid, I was cleaning the floor when James walked in, I moved quickly to cover the condom still sitting in its wrapper on the table top, I knew that I should have told James exactly what had happened, told him that it was his father's fault, no, I doubted that, it was his mother's fault, she had just left the details and the execution to Ron, don't ask me why I didn't tell James, I would have thought I would have taken great delight in telling James all about it, rubbing his nose in what his cousin had done to me and what his own father had told me to do with Mark and his promise to return later with more!

As I carefully swished the wrapped condom into my handbag and set about starting cooking the family meal I realised that I was disappointed, more fulfilled than I had ever been in my life but disappointed, why hadn't Mark used the condom properly, mind you, the answer to that was very likely that he had an eye on the time better than I had, he would have known exactly what he was doing, after all he had planned it, I was just reacting to his scenario, letting him drive everything, I would have happily allowed him to fuck me there in the kitchen and James would have walked in on us.

There was an air, some kind of electricity all around the room, well, all around me really, me and Mark, you could almost see the flash of lightning whenever we passed close to each other, I sent the kids off to have their bath early and when they had their nighties and pyjamas on I read them all a story instead of individual stories for each of them, which didn't please any of them, then I sent them all to bed at the same time instead of staggering them by age as I usually did, that didn't please the girls at all, I did relent slightly, I told Amy she could read for thirty minutes if she wanted too and Laura that she could read for fifteen minutes.

Mark was waiting for me in the living room, I was half hoping that James would be in the living room too so that there would be no chance of anything happening. While I had been reading to the girls Mark had showered, he was now standing in the middle of the living room wearing his dressing gown, James was in his study, "I need to see if James needs anything!" "He's OK; I took him coffee and biscuits when I came down from my shower!" I stepped out of the living room and noticed that the tea tray was leaning against the door to James's study, Mark had set up a 'tell', if James opened his study door the try would fall to the floor alerting Mark that he was on the move.

I was half way to the study door to pick up the tray to take it in to the kitchen when Mark grabbed hold of my arms from behind, his grip was vice like, I was almost picked up and half carried, half dragged back to the living room, as soon as Mark had closed the door he started kissing my neck, he released my arms and started to play with my breasts through my dress and bra. I felt his hard cock pressing against my bottom, first through his dressing gown and my dress and knickers, then I felt him pull his dressing gown open.

Mark moved in front of me, kissing as he went, we were almost dancing around the living room as I was making feeble and half halted attempts to evade his kisses and his grasp. I looked down at his uncovered chest, abdomen and, well, much lower, I kept telling myself not to look, I had after all managed to live with James for ten years without once feeling the need to look at his naked body but I knew from the feeling of Mark's cock against my bottom that his cock was in a different league to my husbands.

When my eyes got to Mark's cock I froze, my inner voice kept telling me that I shouldn't have looked, but I had looked and now I was in inner turmoil, four years without feeling a warm body against my own was a very long time, Mark was definitely nothing like his cousin, he stood there proudly naked, reaching out to pull me against his naked body, well, his dressing gown was still covering his shoulders but his front was totally naked and not a single hair anywhere on his body, just the mop of floppy, dirty blond hair on his head.

Our bodies met, mine fully dressed, his semi-naked, he managed to get his lips against mine and as soon as the tip of his tongue worked its way into my mouth, I knew that I was totally lost. I responded to him, my arms lifted around his neck automatically, my fingers running through the shorter hair at the nape of his neck. We kissed for several minutes but it felt like an hour, as I was busy stroking the back of Mark's neck and head, he was busy rubbing his hands down my sides and over my hips, practiced hands, skilled hands, I felt the sides of my panties rolling down over my hips and bottom, even though his hands remained outside of my dress.

As the soft cotton dropped to my ankles I found myself on the move again, I was being pushed backwards, in my mind I thought that Mark was trying to use my knickers around my ankles as a trip wire to get me on the floor between the back of the sofa and the welsh dresser. I carefully stepped so that my knickers dropped off of my feet, thus avoiding tripping myself, Mark felt them on his own feet and kicked, I thought in anger, I spotted the white cotton in my peripheral vision as my panties sailed across the living room and dropped behind one of the comfortable chairs.

My bottom crashed into the back of the sofa, Mark pushed his tongue deeper into my mouth and was now 'dry-humping' his cock against the front of my dress, rubbing himself somewhere between my pussy mound and belly-button, Mark was so excited that his pre-cum was actually wetting my abdomen through the thin poli-cotton material. Then the tongue left my mouth, I saw his hand reach into his pocket and he pulled out the box, now containing just nine foil wrapped condoms, he took one out, "Here it comes!" I said to myself, deep inside I didn't want him to fuck me, deeper inside I was desperate for him to fuck me, I was listening for the tray to fall against the floor into James's study, I desperately needed an excuse to turn and run away from my cousin. I knew that if Mark didn't fuck me I would probably end up asking James for sex and that would have definitely been very dangerous.

Mark grabbed my arm again, he pressed the condom into my hand and as I was trying to work out how to tear the foil open he turned me away from him, pushed me over the back of the sofa so that I was bent double, he lifted the back of my dress and bent his knees, standing up into me, lifting my feet off of the floor as he took the full weight of my body on his cock, in one violently rapid movement, he was buried, cock, up to his balls in my cunt, I gasped out loud, I wanted to scream, in terror and in relief but I just gasped out loud in pain as my body was violated for the first time in over four years.

Mark fucked me hard for fifteen minutes, fifteen minutes of earth shattering orgasms for me, Mark didn't seem to be getting anywhere close to his own though, I knew that every thrust into my body came with an increased risk of being caught, there was an early warning of sorts with the metal tea tray against James's study door but there were also my three children, any one of them could walk in on us at any time, they seemed to have a built in radar for walking in on me at just the worst moment, usually just while I was wrapping their birthday or Christmas presents as I had never had sex in the living room before. And! And, what if the tray hit James's foot instead of the Oak floor, there would be no warning then.

I wanted to tell Mark to get it over with, I realised that he was showing off, he was holding back his own orgasm so that he could give me a dammed good fucking, and he was doing exactly that, then I heard the pitch and tone of his breathing change, he was getting close, he had lasted ten times longer than James had ever managed and the fact that I was standing, bent over the back of the sofa had increased the feeling for me a thousand times over my usual missionary position sex. Mark's body began to stiffen, his muscles were starting to show his closeness to the 'end game' and then, 'CRASH!' One tin tray hitting two hundred year old Oak, Mark pulled away from me slightly, I almost jumped upright, I felt a sudden rush of scalding hot semen covering my bum cheeks and then my dress fell down over my wet bottom.

As James walked into the room holding the tray in his hand Mark was stepping away from me and was pulling the belt around his dressing gown into a knot, "Where did you find that James?" Marked asked in exaggerated innocence, "It was against my study door!" "Oh god, I'm sorry Cousin, I must have just put it down when I saw Isabella carrying arm's full of dirty washing down the stairs, and I noticed that Billy had dropped one of his cars on the stairs and I rushed over to stop Issy tripping over it!" "Well, at least you did it for the right reason, but please, it's William and Isabella, not Bill or Billy or Issy!"

Mark gave a sycophantic smile, "I'll try and remember Jim!" James raised an eyebrow at being called Jim, "Sorry; Cousin James!" I still had the condom in my hand, I moved my hand behind my back, that was a big mistake, while trying to hide the condom I had pressed the back of my dress against my bottom, the spunk covering my bum suddenly acted like glue, sticking the material of my dress to my backside.

I backed away from James and towards the door he had just entered through, "I need to take my shower, hopefully there will still be enough water for me after everyone else has used it!" James had walked through the door into the kitchen, as I got to the stairs I heard Mark following me, "Can I scrub your back Issy?" I bolted the door as soon as I got in the bathroom, as I peeled my dress off over my sticky bottom I heard the handle turn; Mark was trying to get in the bathroom with me.

As I showered myself I reflected on the day, I had come a long way in less than twelve hours, I had been unfaithful to my husband, I had committed incest, I know that it was Mark who had committed the actual act but I was the older party, it was up to me to have stopped it. Mark had given me the best sex of my life, twice in one day, I counted the masturbation from earlier as that had been my first ever climax at another person's hand.

I would have to check my diary to see when my last period ended, Mark hadn't actually cum in my cunt but I knew that there would have been enough semen in his pre-cum to make me pregnant, I was so fertile that I often said that just being in bed with James would make me pregnant during my fertile period. I had two unused condoms in my handbag now and Mark still had eight in his box, did that mean that I could look forward to eight more incest sessions before Mark went back to Manchester for his court appearance, and after that eight, would there be more incest to come from James's father? Only time would tell!
