Sister Comes To Stay With Couple

This story could have been in any one of a number of categories. 'Loving wives' (mostly), 'first time' (unfaithful), 'group sex' (four together), but I decided on 'erotic couplings'. Please comment on which you feel would have been the right one.

More importantly, I hope you enjoy the story.

"There is no way your sister is coming to live here, temporarily not."

"Why not, I thought you liked my sister?"

"Where do I start? She is a bad influence on you. She flirts with everyone, including me. She is manipulative. She has a terrible taste in men."

"That's a bit unfair; she only got me in trouble once, well okay twice. Yes, she is a flirt, but she flirts with you, because she has always said that she fancies you. I suppose that does confirm that she has a terrible taste in men."

"So, your sister fancying me, makes her flirting with me okay, does it? I think I might find her living under the same roof rather difficult."

"Are you saying that you find my sister attractive?"

"I am not sure that I should answer that question. Whatever I say, could be used against me. You know what effect she has on nearly all men, and in case you haven't noticed, I am a man. She is frighteningly like you in some ways, and I think things could get very awkward."

"Look, I have said she can come and stay until the end of the month. I can't go back on my word, can I?"

Paul had always struggled when it came to his wife's sister, Jen. Jen looked very like her older sister, Patty. They were very different in character, but Paul had always found her frighteningly attractive. He didn't like to admit it to himself and certainly had never told Patty. Patty didn't need to be told. There had always been a certain buzz when the three were together.

The first 24 hours.

Within two days, Jen was on the doorstep with an overnight bag. Her greeting of Paul was outrageous, even by her standards.

"He is looking even more of a hunk than he used to. You must be working out hard in the gym, to look that good, Paul."

She said this having given him a huge hug and stepped back to look him up and down. With the same enthusiasm she added,

"This is where you tell your sister-in-law that she is looking drop dead gorgeous."

Laughing, Paul pretended to be looking her up and down with a critical eye.

"You're looking okay, for an old girl."

"You cheeky fucker, you will pay for that comment. Anyway, what does that make you, if I am an old girl?

Patty decided it was time to calm things down a little and suggested a cup of tea or coffee. The rest of the day was taken up picking up Jen's belonging. By the end of it, all three were exhausted. It was therefore a surprise when Jen announced,

"I am going clubbing. It would be great if you both join me. It has a great atmosphere and the music is spot on."

Paul immediately declined and Patty was not far behind him. Jen was not taking no for an answer and said she would love it, if Patty went with her. Patty wasn't sure how she got talked into it and Paul even encouraged her. The two sisters discussed what Patty would wear. Everything she suggested, Jen rejected, even commenting that some were more suitable for a funeral that an evening clubbing. Jen then started offering her sister her own clothes. Patty was intrigued at how daring most of them were, but did agree on a bright red dress that she had to admit did fit her perfectly and wasn't as outrageous as most. Paul however was stunned to see his wife dressed in a very short dress that showed off her cleavage rather alarmingly.

"You cannot go out dressed, or rather undressed, like that. If you move, let alone dance you will show off your panties to the world. Talking of which, are you wearing any panties?"

It was Jen who answered.

"You can't wear granny pants with that dress. The compromise is a thong."

It was only then that Paul looked at his sister-in-law's outfit. The first thing that he noticed was the lack of bra and a sportingly low-cut front. Jen, like her sister, had smallish boobs but they were being displayed to full effect. Her dark nipples could just be made out through the thin material. Jen noticed Paul studying how her boobs were looking without a bra and smiled as she said,

"I never like to compromise, particularly when I go clubbing."

With this she smoothed her hand across her bottom. Her brother-in-law wondered whether she was illuding to what he thought she was, but tried to shrug it off. He was still wrestling with this image when Patty kissed him on the cheek and was on her way out of the door. With a huge smile, Jen copied the kiss and skipped out of the door.

It was only then that it fully registered how little his wife was wearing and that he hadn't really challenged it. As the evening went on Paul did just wonder how the 'girls' were getting on. He found himself fantasizing and was rather disturbed that these fantasies always involved Jen, not Patty. They involved her dancing with a number of men, with her dress barely covering her naked bottom. He watched a film to take his mind off his fantasies and retired to bed at midnight.

It seemed like the middle of the night, when he woke to find his cock being sucked. He feigned sleep initially as he woke slowly and checked he wasn't dreaming. The mouth made no attempt to tease his cock. It felt much more like his cock was being prepared for something more, with great urgency. He felt for the body kneeling beside him on the bed instinctively finding a naked pussy with great accuracy. The fact that while there were no panties, there was still a dress around the waist, instantly sent his mind into overdrive and his cock became erect in record time. His fast-waking mind came to a simple conclusion. Given this conclusion, he decided that maintaining the pretence of not being awake was the prudent option.

Things moved fast and he was soon on his back, being mounted with the same urgency, as he had been sucked. This was like no sex that he and Patty had enjoyed for a long time. The excitement of this almost frightening coupling, was intense and Paul couldn't keep his pretence up, as he gripped the hips that were riding him and fucked the dripping pussy hard and fast. The couple exploded at the same time, within less than two minutes.

"Fuck, I needed that I have been as randy as hell all evening."

His still slightly confused brain, took a few seconds to register that the voice was that of his wife, not as he had presumed his sister-in-law. Before logic kicked in, he did have a very brief flash of disappointment, before relief took over. They were both asleep within a minute and when he woke in the morning Patty was still in a deep sleep. She still had her sister's dress wrapped around the middle of her body.

Paul left her to sleep, going downstairs to make coffee. He sat remembering the encounter from the night before. He had loved how it had been so intense, but disturbed that it might have been partly due to the fact that, he had thought he was fucking Jen. His eye spotted Patty's clutch bag on the floor, which was partly undone. He was shocked to see that her bra had been stuffed into it. This got his mind thinking about the fact that Patty had been pantie-less when she had arrived in their bed. He didn't have time to develop this thought before a bleary-eyed Jen staggered into the kitchen.

"Fuck, that was a great evening last night. You should have been there; you would have loved it. You should have seen your wife, they were like bees round a honey pot. I barely got a look in. She danced until I thought she would drop. My friends loved her. One wanted to come home with us, well to be honest, I think it was more that he wanted to come home with Patty. I nearly agreed as I would have very happily taken one for the team, if you know what I mean. I was totally revved up, but Patty refused to let me come and join you two in bed when we got home. It did sound explosive in there for a few minutes."

Paul felt bombarded by Jen's excited commentary of the previous evening. She had said so much and created so many very different images in his mind. Unlike the previous evening, these were almost exclusively of his wife. The images were often completely unrealistic, but they aroused him just the same. One he couldn't quite shake of was of Patty dancing, surrounded by a number of men with her dress around her middle as it had been when he left her in bed.

He made coffee for Jen and tried to change the subject, asking her questions about the breakup of her previous relationship. In her normal very direct way she gave him far too much graphic detail of how her ex had not been 'doing it for me'. She gave Paul a sly look and added,

"Sometimes I think my big sister might have actually got things right."

"What do you think I might have right, little sister?"

"Well you seemed to have things about right last night, when we got back from the club. It was me who turned down a dead cert with Jason last night and had to hear you getting screwed silly instead."

"So you thought that Jason was a certainty for you last night, did you? I thought that... well never mind. I am sure you were right."

It was Paul who with a teasing laugh said,

"'You thought that', what my dear?"

Patty immediately went bright red and tried to change the subject. Paul was not quite finished winding his wife up and absently handed her the clutch bag that was still not closed. He did just comment,

"From what I can make out you had a very exciting evening. I am far from sure that I should let you go again, it sounds quite dangerous, out there. Mind you if I thought I would receive the fringe benefits like last night, well..."

It was Jen who couldn't help but jump in with,

"I was up to double those fringe benefits, as you put it, but my big sister was very selfish, and I went totally without. I am of half a mind to take my ex up on his offer, of him screwing the arse off me, with no holds barred and nothing other than uncomplicated sex. I think my style is going to be badly hampered while I am living here."

With this Jen disappeared upstairs, saying she was going for a shower. Patty was clearly shaken by the conversations and fell very quiet. Paul was a little confused, but the sexuality of the whole discussion had left him aroused. He comforted Patty, reassuring her that everything was okay and that he was not angry with her in any way. They also retired upstairs for a shower. Unusually, Patty joined Paul in the shower after he had finished washing. He made to get out as she got in but she put her hand on his chest to stop him. She put her finger to her lip, before dropping to her knees.

Her mouth felt totally different to the night before, as she teased his cock and added her hands to his shaft, his balls and his bottom. The water was still full on, and Paul took the showerhead off the wall and played it directly onto his wife's head. As different as it was to the night before, there was a freshness and enthusiasm that their sex had sometimes lacked previously. Although she teased, and was not too demanding, it was not long before he was getting close to loosing control so brought his hand down to her head to warn her. She knew exactly what he was telling her, but only redoubled her efforts and was rewarded as he squirted forcefully into her receptive mouth. His knees buckled as he squirted, time and time again, before there was nothing but a dribble settling on her tongue. She stood up and ushered him out of the shower, but not before demanding that he kissed her mouth, that still retained a small amount of his jizz. As he dried himself, Paul reflected that maybe his sister-in-law staying did have some real upsides.

As for Patty she felt relieved, that far from causing a major problem between her and Paul, everything that had happened in the last 24 hours, had seemed to work out more than okay. She smiled to herself as she played the water across her erect clit, but didn't take it any further.

A week later

The three did not spend a lot of time together, during the week, as Paul was away for much of it. When they did, there was lots of banter, with lots of innuendo and teasing, often sexual in nature. Jen had taken Patty shopping to get an outfit for clubbing, on Friday night. Patty didn't tell Paul, as she knew that he would not want her to wear what she had bought.

It was very different to the dress she had borrowed the previous weekend. This was tight fitting, very short, but not flaring out at the bottom. With the top fitting tightly across the bust, the two sisters had agreed that there was no way a bra could be wore with it. It was dark enough for the darkness of her near black nipples not to show through. However, the thinness of the material did little to hide the shape of her chunky nipples, particularly when they became erect.

As time approached for her to get changed Patty became very nervous of Paul's reaction to the outfit. Jen had the whole situation under control and smiled to herself when, right on time, Paul's mobile rang. Paul never realised that the invite for a quick pint from his best friend had been set up by his sister-in-law. He put his head round the door of the bedroom, where the sisters were dressing. Jen turned at just the right time to give him his first view of her totally naked boobs. She made no attempt to cover them as he explained that he was just popping out for a quick pint.

Patty was delighted, to be able to relax and get dressed without worrying about her husband judging her outfit, well at least, before she went out. As she slipped her newly purchased thongs, Jen simply said,

"No."

"But I can't go out without anything under my dress."

"You came home without anything on under your dress last week."

"Yes, and I blame you and the drink for that. I am stone cold sober right now and it just does feel right. Don't you think that some men might think it is sexy to see that I am wearing a thong?"

"You obviously meet a better class of man than I do. The ones I meet, firstly see it as an invitation, and secondly think it saves time later."

Patty laughed at her sister and responded with,

"I haven't met any class of man, other than Paul, for a very long time. It was nice last weekend, to be noticed, to feel someone new fancied me, to feel sexy. Don't get me wrong, I am not going clubbing with you to get laid, by anybody. I love Paul and wouldn't do anything to hurt him. The evening dancing last weekend, revved me up perfectly. Paul didn't know what hit him."

"I know, it sounded great. My fingers were a really poor substitute for a stiff cock. I suspect, if you had not been there, Jason, I think his name was, might have been fucking me senseless most of the night."

"Oh, it never occurred to me, but I totally cramped your style. Maybe it would be better if you went out by yourself tonight."

"I have been going clubbing now for years. I have not had half the interest shown to me during one evening as I did last week. You were a man magnet and I loved it. Come with me. I am not asking you to screw anyone, but keep the men just interested enough. Maybe tonight, I will get lucky."

The sisters understood each other and Patty offered her sister a hug before they went out. Patty was now comfortable with her outrageous outfit, comfortable with the idea of dancing with any man who attracted her, comfortable with being her sister's support act.

The evening was busy, for both of the sisters. It was hot in the club and the energetic dancing left both girls perspiring well, but loving the non-stop attention. At around midnight Patty found herself dancing with Jason, who she had met the previous week. She remembered how her sister had been frustrated, that by being there she had frustrated her interest in the young man. She would have rejected him when his hands found her naked cheeks, but she resisted so as not to upset him. He took this as permission to carry on and when his fingers found her anus she did call a halt. She was very aroused by having her anus tickled, while dancing in the middle of a busy dancefloor, but knew that she had to stop it.

She was pleased when he made light of her rejection, and rejoined a small group including Jen, who greeted him warmly. Jen seemed to sense a little tension between Patty and Jason, but rather than let it worry her she said,

"If we go back to our place, you two could find a quieter place than the middle of the dancefloor."

Patty was furious with this intervention from her younger sister, but decided not to challenge her, as she knew that Jen was keen to get Jason back to the house. When they arrived at the house, Paul was surprised to hear them back so early. He was also surprised when Jason walked through the door. The girls hadn't mentioned Paul to Jason, who slightly nervously said,

"Oh, I am sorry I didn't realize that there was a boyfriend around."

"Husband, actually, but don't worry. Can I get anyone a drink, I could do with one."

Jen put some music on, and by the time that Paul was back with the drinks, Jen and Jason were dancing. It was only really at this point that Paul register how the two sisters were dressed. Patty's nipples were very erect, making her braless state very obvious. She saw her husband noticing this, instinctively closing her legs tightly. She now felt very aware of her lack of underwear. He was confused with his own reaction, which was a mixture of being stunned and being excited. Trying to reconcile these he indicated that she should join in the dancing.

Patty was relieved that Paul didn't seem to be angry with her and was soon dancing excitedly with the other two. The drink and the music took her over and she was quickly completely engrossed. It was Jen who came over and invited Paul to join in the dancing. When her initial invite was rejected, she changed her approach and kissed her stunned brother-in-law. He didn't fight this, as it cranked up his already high level of arousal.

Jen couldn't miss his positive response to the kiss. She cuddled up to him and dropped her hand to find his cock. He tensed as the implications of what was happening hit him. Far from drunk, but highly aroused he just didn't fight it, until his cock was as hard as steel. By this time, it was just too late to stop it, and he knew he didn't want to. Patty had also given in to the sexuality of the situation. Somehow, the fact that Paul was watching her, did exactly the opposite of what she expected, and she felt freed up. This time, she didn't push Jason's hands away, as again they ventured under her dress at the back.

Seeing Paul kissing her sister excited her beyond belief. It wasn't the hands exploring her cheeks that shocked her pussy into melting, it was seeing her sister seeking out her husband's erection. Jason immediately sensed the change in atmosphere and kissed the confused Patty, before she had the chance to question it. Her eyes closed and stayed closed as the kiss caressed her lips.

Things had fallen perfectly for Jen. She had wanted to seduce her sister's husband, since before they were married. Now her prudish sister was dancing in the middle of the room, nearly naked, kissing another man as he fingered her anus, while her husband watched her. Paul's cock was rock-hard and Jen knew that it was mainly due to what Patty was doing, not her own actions. She saw her chance, there were risks involved, but who could blame her, she took the gamble. His erection was in her mouth before Patty opened her eyes.

The look that the married couple exchanged communicated more in five seconds than they often shared in days or weeks. Patty's expression included; denial, shock, questioning, arousal, but most of all a request for permission. Pauls mainly included; shock, apology, questioning, arousal, acceptance and finally permission. Neither knew what might happen, or what permission was being sought or granted. But both knew it had been granted, by both of them.

Jason was disappointed as Patty eased herself away from him. She took two steps towards Paul before holding his gaze again. There were three shocked observers, as very slowly she took hold of the hem of her dress and pulled it up and over her head.

Paul had seen her naked thousands of times but never like this. Everything he saw was new, everything he saw was perfect. Her small firm breasts capped with button-like nipples, that were more than half an inch long and even wider, looked almost painfully erect. With no areola the dark nipples stood out very prominently from the pale skin of her breasts. His eyes drank in every inch of her flat stomach, before they were invited to explore between her legs by the triangle of shortly trimmed dark pubic hair, that seemed to be pointing to her pussy, demanding him to drink further from the view. What he could see of her pussy was slightly flushed with a hint of a dark sheen. He sought her clit, hoping it would be prominent but contented himself that the area did seem swollen.

Without taking her eyes of his, she knew her sister's mouth was wrapped round his cock, a cock that was hers to suck. She knew what she wanted, what she needed. She was kneeling with Jason's cock in her mouth, within seconds. He looked a little bemused as he stood with his trousers around his ankles and his cock growing from aroused to rock-hard in seconds. Patty had shocked herself by how quickly things had progressed, how quickly she had progressed them. Now she tried to slow herself down.

She had not seen a cock, other than Paul's, for years and now wanted to enjoy it to the full. She had not really registered what size he was, something that shocked and surprised her. Now she explored his balls and started to really play with the cock in front of her. She knew what she wanted and she was sure that she would not be disappointed. She wanted sex, simple uncomplicated sex. Paul and her had not had sex like the previous weekend for a very long time. They made love regularly, but last weekend, brief as it had been, they had had sex. She had loved it and was ready for more, right now.

His cock was very similar to Paul's. She tried to study it without being too obvious about it. Her conclusion was that it was probably slightly shorter but maybe a little thicker than her husband's. She did particularly like the large purple head that felt silky against her tongue. Jason's hands were holding her head, but were not demanding. There were four people in the room, all fully engaged. Somehow all three realised that, for some unspoken reason, Patty was in charge. She wanted so much, but her next actions were going to result in things moving fast, very fast. It was as if she couldn't stop herself saying what was in her head, what she seemed to need so badly.

"Jason, I wanted you to fuck me. Show my husband what it is like to watch another man fuck his wife. Paul, I want you to fuck my sister until she doesn't know which way is up. She has been wanting you to do her for years, I am sure you won't disappoint her."

There was a stunned silence, as Patty still clearly in charge, moved towards where her sister and husband were sitting. She turned away from them, knelt down, opened her legs and dropped her shoulders to the floor. Her fingers found her clit before she added,

"Sis, get down here and offer yourself to Paul. Do it now."

Nothing more was said until Jason was kneeling behind Patty and Paul was kneeling behind Jen. The two sisters were beside each other before Jen said,

"Just wait for a minute before you fuck me. Watch your wife take another man's cock. I have been told by my ex that there is nothing more exciting."

Patty couldn't believe how perfect her sister's words were. When Jason eased his erection into Patty it was close to perfect for all four. Paul did panic briefly when his excitement threatened to spill over. He offered up his cock to his sister-in-law's very ready pussy, but again she just said,

"Give it one more minute, I think you wife is just about to explode."

Jen had read her sister's excitement perfectly. Jason had only been fucking Patty for a minute and with a frustrated wail her fingers found her clit, just before her violent orgasm exploded spectacularly. All the way through her long violent climax Patty kept screaming, then moaning and finally whispering, "no". Every one of them meaning something different.

Paul in near panic couldn't contain himself any longer and penetrated Jen hard and fast. He took hold of her hips and fucked her hard. He prided himself on being able to control himself while making love to Patty, but now he had a problem. He held off the inevitable for as long as possible. Jen loved the urgency of things, but was not going to get there before Paul started to empty his balls deep inside her.

Patty was apologising to Jason for climaxing so quickly. Jason was delighted to have watched the gorgeous Patty totally disintegrate on the end of his cock. He had loved it but had not cum himself. He didn't stop fucking her completely, but just stroked in and out of her gently. She seemed to be happy with this, but a little uncomfortable when he thrust a little harder. It was Jen who broke the silence,

"Well, if that is what getting married does to you, I am not sure whether to go for it or not. What a couple of lightweights. Mind you, you seem quite happy still, old girl. As for me, your husband has got be all revved up with nowhere to go. I am sure that we can get him interested again, but I must admit to being rather in need of a hard cock right now. Are you up for a little sharing, Sis."

Paul was now sitting on the floor watching as his wife got slowly fucked. It took Patty a second to realise what her younger sister was suggesting. She had started to recover from her devastating orgasm and while she never orgasmed twice was beginning to enjoy Jason's very understanding and undemanding attention. She felt a little guilty for having been so needy, and understood that her sister might be frustrated.

"Do you mean that you want Jason to take turns fucking both of us, or are you trying to take him all for yourself?"

Jason's evening had been great, but it was just getting better by the minute, when Jen replied,

"Oh no. I would not be greedy. If you are still happy, he could take turns with us."

Jason needed no second asking and was balls deep in Jen within seconds. He fucked her firmly using her hips to ensure deep long thrusts had her moaning her appreciations. He was soon building towards losing control. He had the perfect excuse to pull out of her and re-enter her sister. In the seconds it took he was back under full control. As for Patty, much to her surprise her pussy welcomed the new invasion as if she hadn't had an orgasm in days. She wasn't close to having a second orgasm when Jason swapped pussies again, but she was hoping that he was up to returning again. In total Jason swapped pussy an amazing five times. The visits were getting shorter as his cock grew impatient. When he left Patty the third time she was on the brink of a second orgasm.

Jen had realised why Jason's timing was as it was. When he visited her for a third time she was finished with sharing. She had loved everything that had gone on, but was now desperate for the relief of an orgasm.

"Don't you dare stop fucking me again until I have cum all over your cock. Do you understand?"

Jason understood and was actual happy to be able to concentrate on himself and the one pussy in front of him. As for Patty, her heart did sink slightly, as she realised that she was not going to experience Jason fucking her to the mutual orgasms she had been hoping for. Paul had been somewhat forgotten, but had been watching with great interest and excitement. He had been fully erect, for some minutes but had not wanted to interfere with the other three's obvious pleasure.

Patty was delighted as he entered her with the greatest of ease. The technic of the two couples was quite different until Jen interjected,

"Paul, stop making love to the poor girl and fuck her. She doesn't want gentle stroking she wants a big hard cock fucking her into next week. Go for it, show her your urgency but don't stop until she cums all over you."

Not for the first time, her little sister had read Patty perfectly. They were close enough for Patty to reach over and squeeze her sister's hands, to thank her. Both pairs now fucked with urgency and purpose. Jen's much needed orgasm was not long arriving triggering Jason's. Hearing Jason excited Patty and started her rise towards her second and surprisingly strong climax. As nearly always, seeing his wife orgasm excited Paul so much he came after fucking her all the way through her strong contractions.

Jason and Jen disappeared shortly after, not to be seen until the morning. Patty and Paul retired to bed and chatted about the evening. Both were delighted that the other seemed very comfortable but also very excited by events. The last comment before they turned the light out was from Patty,

"My little sister has been with us for a week and it has been the most exciting week of my life. I cannot even start to think what will happen, if she is with us for a month."

Paul struggled to sleep, as his third erection of the evening was fuelled trying to imagine the answer. His imagination was far too successful for him to manage sleep for over an hour.
