As Paul lay there, he wondered how he found himself in this situation. Here he was, lying on his bed, next to his wife, Megan, at twenty five, the same age as Paul. Also on the bed was Mark, Megan's younger brother. All three were naked, the bedsheets ruffled, wet with sweat and sperm.
How had this happened, Paul tried to understand.
Today was Thursday. Last week Megan had received a phone call from her parents, asking if it would be ok for Mark to come and stay. He had got into a bit of trouble at college and seemed to be unsettled. Maybe a few days away from home would help him clear his mind. Megan had agreed, and on Sunday afternoon Mark arrived at the train station. He lived about thirty miles away, and had to catch a bus and then a train to get to his sister's house. Paul met him, and then drove him to the house where Megan and more importantly a nice hot meal awaited.
Paul and Mark had always got on well together, with Mark looking up to his sister's man as a kind of big brother.
Paul and Megan had started dating about six years ago and finally married about eighteen months ago.
Just recently some tension seemed to be creeping into their relationship. Work and tiredness and the lack of money seemed to be coming between them, and as a result their sex life in particular was not very eventful. Paul was still keen but Megan didn't seem too bothered and on the rare occasions when they did make love she lacked passion and interest. Paul had suggested spicing things up a bit, but nothing seemed to excite his wife. He worried that she may be having an affair but some subtle investigating seemed to rule this out. The only suggestion of his that sparked any curiosity from her was when he mentioned a threesome.
"Possibly", Megan mused. "What did you have in mind? Another woman or another man. Someone we know or a stranger?"
"I don't know. I was just thinking out loud", replied Paul, slightly taken aback that his wife hadn't dismissed the idea out of hand.
That was about a month ago and the subject hadn't been mentioned since.
Now Mark was here. After he arrived they had dinner, watched a bit of tv, then Megan went to the shop for a bottle of wine while the boys played on the xbox.
"I'm going to have a bath, you guys. My shoulder's still playing me up a bit," said Megan.
"What's wrong with your shoulder? Getting old Megs?" teased Mark.
"HA HA! Watch it kid or else you'll be on the next train to mum and dad. Just been aching lately. Too much work," she retorted.
At about a quarter to ten, she reappeared in the living room, wearing a dressing gown. The other two were watching some documentary about sharks on tv.
Paul looked at his wife, then stood up. "If you two don't mind, I'm going to bed now. I feel tired and I've still got a bit of a cold. See you later".
Megan kissed her husband, told him she would follow soon and then sat down on the sofa.
Mark went off to the bathroom to get changed, and to fetch the spare duvet and pillow for his 'bed'. His sister's flat had only one bedroom, so Mark was going to sleep on one of the two sofas in the living room, while Megan and Paul slept in their room, the next one along the hallway.
Mark returned twenty minutes later, carrying the duvet and pillow, wearing only a pair of boxers. He sorted out his bedding then climbed under the duvet.
"Do you want some more wine?" asked Megan.
Mark nodded so she went to top up their glasses, popping into her bedroom on the way.
She came back to the living room.
"Paul's already asleep. Ouch!" she exclaimed as she put the wine glasses down.
"You ok sis?" asked Mark.
"Just this shoulder. I yank it occasionally and it really hurts."
"Would a massage help?"
"Would you? That would be good."
Mark got up and moved to the other sofa. Megan stood up to let him sit down, then she sat down again, her back to him, sitting between his open legs. He started to massage both her shouders.
Meanwhile, in the bedroom Paul was not asleep, in fact. He was tired, but could not sleep, so he lay there eyes closed, trying to nod off. He could clearly hear the conversation in the living room.
"Ooh. Aah. That feels good. Oh yes, you're good at this Mark," sighed Megan, as her brother rubbed her shoulders.
In the next room Paul smiled to himself. "If I had a dirty mind, that sounds like she's having sex," he thought knowing that she was having a shoulder massage.
"OH God! Yes that's perfect. Keep doing it Mark," Megan said.
Mark carried on massaging her shoulders for a while, stopping only for each of them to have a sip from their wine glasses.
After another ten minutes had passed, Megan gently lowered her dressing gown off her shoulders, allowing her brother to massage them on the skin rather than through the wool of the gown.
This meant that as he rubbed, he could see the rising of the top of her breasts. He started to get a bit horny, changing the mood of his actions from innocent to a bit sexual. Even though this was his sister he was getting turned on.
He rubbed a bit more then for no obvious reason he moved his right hand slowly down from her shoulder, into her gown and down on to her breast. Expecting her to push his hand away, at the very least, instead she did nothing. He stroked her delicate skin, squeezed her hard nipple. Never before had he seen or felt his sister's breasts. They were small, size 34AA, but he thought they felt perfect.
After five minutes he moved his left hand down in the same way, on to her other breast.
"Mmmm. Nice oh yes," breathed Megan as he fondled her breasts.
Paul listened, smiling at the way her voice sounded as though she was fucking. His mind started to wander, imagining that she was actually having sex and he started to get an erection.
Back in the living room, Mark also had an erection as he stroked his sister's tits.
Megan suddenly got up. "Hold that thought young man," she whispered to her brother. She went into the bedroom, tiptoeing so she did not make a sound. She leaned over her husband, then satisfied he was asleep she went back to the living room.
Again she sat down between her brother's legs but as she did so she opened up her dressing gown and lifted it up, so her bare arse pushed against his crotch. Mark once again fondled her breasts and let his hands wander down her tummy towards her legs. Her gown was fully open and for the first time he saw her tits and lower down a neat tuft of pubic hair.
"Oooh. You don't shave?"
"No Paul likes the hair. He doesn't like it bare."
Paul tried to hear this but couldn't quite make out the words. He heard 'shave' but not enough other words to form a sentence. He had now given up trying to sleep and was lazily stroking his erection, his perverted mind trying to picture what it would be like to see his wife with another man. Even her teenage brother? "I'm sick, " he thought.
Mark's right hand slowly moved down through the soft pubic hair and to his sister's vagina. As his finger gently entered her slit and began to probe she pushed her bare arse further against him, feeling his hard cock pushing at the material of his boxers.
He fingered her cunt, getting faster and harder as she began to moan, louder and more erotically.
"He's good at this massage stuff!" thought Paul, in the other room.
With his left hand, Mark freed his cock from his boxers so that it was pressed tightly against her arse cheeks. He continued to rub her vagina, finding her clit and make her thrash up and down on the sofa. Her arse constantly rubbing against his cock. She nearly had tears in her eyes as she whispered breathlessly to him "I'm cumming. Oh!!"
As she said this his own orgasm hit, sending jets of sperm over her arse, back and his chest. He could feel her juices on his fingertips as she relaxed, leaning back against him.
"You naughty boy! What am I going to tell mum and dad?" she laughed at him as she stood up, pulling her gown back around her.
She kissed him goodnight. "Never again, " she said wagging her finger at her brother as she headed out the room to the bathroom to clean up.
As she passed the bedroom, Paul was trying to work out what he had heard. Moans, sighs, creaks from the sofa springs and then Megan calling her brother a 'naughty boy'.
"No way. It's just me being sick," he thought as he stopped stroking his shaft and rolled over to try to get some sleep. Megan came into the room, removed her gown and climbed in the bed.
"Goodnight, darling. Sleep well."
The next morning Megan was up and off to work before the other two awoke. Paul was next, leaving Mark free for the day. He played on the xbox, watched some tv and chilled in the small back garden. It was a nice warm, sunny day, so he did a little bit of gardening, thinking it would be a nice way to show his appreciation that his sister and her husband had let him stay. He had been having a hard time at home and at school lately and this break was just what he needed. Although Megan was seven years older than him they had always been cool with each other, her playing the big sister role perfectly. In fact the age gap was ideal because she was young enough to understand still what the teenage years were like but old enough to give advice. However there had never been anything remotely sexual about their relationship, although Mark would admit that deep down all potential girlfriends were compared to his sister, because she was his sort of role model. He liked Paul too, and always enjoyed visiting, although when he did his parents normally came along too.
Now on this sunny afternoon he was doing a bit of weeding, wearing only a pair of shorts, replaying last nights events in his mind. He hadn't planned it or expected it. He didn't know why he had suddenly lowered his hand to Megan's breast and felt slightly embarrassed about it in the cold light of day. He hoped and prayed that it would not change their closeness or make them awkward around each other. He was scared that his whole family would suddenly fall apart because of what happened last night. He had even started to repack his bag, half expecting Megan to send him home when she got back from work. Of course she could have stopped him at any point, but he still felt he was the one to blame.
At about three pm Megan got home. She looked out the kitchen window and saw her younger brother outside. She poured a glass of water and watched him for a few minutes. She had also been thinking about last night, although not as much. She enjoyed the massage, especially as the whole three months she had this shoulder problem, her husband had not offered to help, but a massage was just what she needed. That and a few glasses of wine had made her a bit loose. When she lowered the shoulders of her gown it was to let him get closer to the area of pain but also because it felt so damned good. When he touched her breast she just let him carry on, thinking nothing of the morals. Maybe he needed some release to his frustrations too? What happened after that just crossed too far - she knew that today - and had decided to talk to him and clear the air, also fearing a breakdown in their relationship.
She went outside.
