I had just awakened and was going downstairs when I heard two women talking. I rounded the corner and saw that it was Jessica, my sister-in-law, and Becky, my wife. I was about to go in when I heard Jess say my name. I decided to stay hidden and listen what it was about. I found out that Mark and Jess where trying to have a baby and the reason they have been unable was because Mark had low sperm count and the chances of Jess becoming impregnated by him was slim to none. She asked Becky if she was okay with me doing the deed. Imagine my shock when I heard Becky say that it was okay. Stunned wouldn’t even begin to describe what I was feeling. Yes Jessica was very beautiful looking and I would be lying if I said that I didn’t have fantasies of me fucking the living daylights out of her. But never in a million years would have I thought that I would get to do just that and with my loving wife’s blessing. I just quietly went up to Mikey, my two year old son’s room to check in on him.

After that day I begin to wonder when Jess or Becky or even Mark would approach me. Then again, I wondered even if Mark knew about Jess’s idea or if it was something the girls had come up with. I decided to act as if I hadn’t heard them talking.

A couple of weeks passed after that morning and I started to wonder if it just was a joke and maybe Jess wasn’t serious about the idea or Becky had changed her mind. But then on Saturday afternoon I got a call from my brother inviting us to their place for dinner.

We were sitting in the den after supper and by the looks of those three I knew that one of them was going to broach the subject. I decided to play ignorant. I already had made a plan.

********

First let me tell you guys about us. Mark and I (Steve) are brothers. We both are blonde haired, blue eyed. Mark is couple of years older than me. He is 29yrs old while I’m 27. Jessica or Jess as she prefers to be called and Becky both are beautiful brunettes. Jess is 28yr old while Becky is 26. Jess has an amazing figure of 34-26-35 while my wife has a figure of 34-25-34. They are more or less similar figure with my wife being just a touch slimmer than Jess. Becky and I have been married for the past three years while Mark and Jess have been married for 6yrs.

*******

Mark started first. "Well bro, Jess and I have something to ask you."

I looked at him suspiciously. "This sounds scary."

Jess had been looking at Steve all evening. She had not really noticed how good a shape he was in and had not really noticed the large bulge in his jeans before.

"As you know Jess and I have been trying to have children but we found out that the problem is my low sperm count."

I said, "Hey, no problem. I'll gladly donate sperm at the sperm bank."

"That's just it," Mark replied. "We can't afford artificial insemination. We need to...to provide sperm the natural way."

"You're shitting me!" Then I glanced at Becky. "You know about this and are agreeable to it?"

"It's for Jess and Mark," Becky said trying to keep calm. "I know you love me and Mark knows Jess loves him. You know how happy we were when we had Mikey."

"Yes, but this is very intimate and we can't take it back once it happens."

"We know," Jess said finally speaking up. "It will just be as mechanical as we can do it."

"Wow...this is crazy. Becky you know that I've never wanted to have sex with another woman besides you."

"I know," she smiled, holding my hand.

"No one else can know. We all have to swear."

"We swear," Mark said, checking out Becky's cute little body. He started wondering if maybe he could mess around with her while I was fucking Jess.

Becky saw Mark's eyes on her body and realized what he was thinking. Even though they had only been married three years, their sex had dwindled to maybe twice per month. She too had read stories about couples getting together to get one wife pregnant while the other two spouses messed around at the same time. She didn't think Steve would go for that, at least not until he started having real sex with Jess.

"Honey, we all want this to happen. Mark and I feel comfortable that it will only be with one purpose in mind."

I looked at Jess's nice round chest. She had at least two cup sizes on Becky. "Well hell, why not? When do we start?

"I knew it wouldn't take much of a fight," Mark laughed, even though he was still not sure about this.

"This is almost my fertile time," Jess said nervously.

"Tonight?" Mark asked. "Are you anxious?"

"Mark, if this is the way you are going to act then we should call this off," I said quickly. "I don't think Jess or I really want to do this but it is needed for you two to have a child."

"Also," Becky chimed in, "In order for it to work it needs to be done more than once. We have to increase the odds."

"Shit," Mark said softly. "I hadn't figured it would be more than just once. How long is this going to go on?"

"At least two weeks," Becky said.

"Two weeks!" Both Mark and I said loudly at the same time.

"Two weeks, as often as Steve is able to do it."

Even Jess hadn't planned on doing it with me every day for two weeks. "She's right. We do it for two weeks and hopefully that will be it."

"Steve is on summer break from his teaching job and since you are home there shouldn't be any problems with time," Becky grinned. She glanced at both men's crotches and noticed we were both turned on.

Everybody all got quiet as they considered what the next two weeks would be like.

"I don't think I want to be in the house while you are doing it," Mark said looking at Jess. "Maybe Becky and I can go to the movies or take some walks."

"Uh....yes he's right," Becky smiled. "We shouldn't be here."

"So do we start tonight?" I asked, knowing that my pants were about to burst open.

"Mark and I can go to our house. Mikey is with your mom," Becky said standing up. She looked at her watch. "It's almost 8PM. We will be back around 10PM."

"Two hours?" Mark gasped.

"It's the first time and I'm sure they will be nervous," Becky said. "It can't be rushed to the point where the yield will be affected."

"The yield?" I asked.

"Of sperm."

Mark decided to set another rule. "Also, you can't be naked while you are doing it. It uh...should be dark and Steve just pulls it out and you slide up your gown and don't really see each other."

Jess laughed. "You're joking right? We're going to be having intercourse for two weeks straight and you are worried about us seeing each other naked?"

Mark looked at me and said, "It's supposed to be mechanical with no foreplay."

I glanced at Becky. "What if I have problems you know...getting it up?"

Becky looked at the obvious hard-on pushing up my pants. "From the looks of that and the fact that you are always horny, I don't think that's a problem."

Jess could see that Mark was wavering. "That's fine. If it happens we will have to revisit the rule. We all want to make a baby, so please let's try it," she said.

It was strange walking our spouses to the door so that we could go upstairs and have intercourse for two hours. It was also strange for Mark and Becky, leaving their spouses behind to have sex.

After the door closed we stood looking at each other. "I think we should go slow," she smiled. "I've always thought of you as my little brother."

"Same here, but I've also fantasized about you."

"You have?" Jess asked, surprised. She realized she had known me since I was fifteen years old. "Let's go sit down on the sofa for a while."

Jess also asked me if I wanted a drink but I declined. "So, I guess we just need to do it."

"Right. We said to make it mechanical. Where do you want to do it?"

She glanced at the large rise in my pants. "I don't think there will be an erection problem. You've been that way since we started talking about it."

"I know and I'm not sure how long I'll last since I'm really turned on."

"We have two hours," she giggled. "Give me five minutes to go upstairs and get ready."

I watched her go and thought about my wife sitting in our house with my brother while we had intercourse. They said it was to produce a baby but I was going to fuck my brother's wife, mechanically or not. I looked at the clock and sat nervously for five minutes.

"I'm ready!" Jess yelled.

I reached into my pants and guided my eight-inch hard cock upward towards my navel. I knew Jess would be calling the shots and wondered if she would allow any foreplay or kissing. I stopped at the master bedroom doorframe and knocked.

"Come in, silly," she giggled.

I didn't know what to expect. I peeked around into the room and saw candles lit on the two night tables. She was lying on the bed wearing a long black nightgown with thin spaghetti straps. "Wow...you are so beautiful". The candles gave off enough light for me to see her nice round titties and hard nipples pushing out the black silk.

"Thank you," she blushed, feeling weird that her young brother-in-law was seeing her like this. "Come closer."

I walked to the bed and waited.

"I guess you should undress to...to your underwear. I mean, you won't be really naked."

I quickly jerked off my shirt and pushed down my slacks. I stood upright after pulling my socks, shoes and pants off my feet, proudly displaying my bulge of affection.

"We said to make it mechanical," she said. "So why don't you crawl up here between my legs?" She slowly pushed her legs outward while pulling up her nightgown, making sure to keep her pussy covered. "I'm not wearing panties."

"Oh...ok," I said, looking at her delicious creamy thighs, hoping she would wrap them around my hips as we fucked. I moved onto my knees between her legs and reached into my boxers to find my hard cock.

"Wait, lean forward. We uh...can't see each other." It hit her that this was really happening.

******

"How much time is left?" Jess asked me as I fell off to the side. She had her eyes closed and her legs bent to keep my cum inside of her as much as possible.

I moved onto my elbows and leaned over her to see the lit alarm clock on the night table. "About thirty-minutes."

She felt my erection against her hip. "God, are you hard again?" She had never been fucked three times in one night.

"I've stayed hard," I bragged. "Do we have enough time?"

"Yes....hurry and put it inside again," she giggled, dropping her leg closer to me and reaching out to guide me home again. We had no problem lining up our bodies as my hard cock pushed into her cum dripping pussy. "Ohhh...yes," she whispered.

I reached under her and cupped her bare ass this time. She didn't object that my fingers were on her bare buttocks, so I took the opportunity to caress and explore while my hips drove my manhood deep inside.

"Kiss me," she commanded. Again our lips met and parted. We both forgot about the main purpose of making a baby. Our present purpose was to cum again. "Fuck me Steve...fuck me," she whispered, while her lips and teeth nibbled on my earlobe.

"Ah...Ah...Ah...Ah!" She moaned each time I bottomed out.

"Fuck me, Steve...fuck me!"

"Hurry...faster...don't stop!" Jess cried. "I'm close...so close. OH SHIT!!!"

I came again, deep inside of her. I squeezed my cock a few times until I was empty. "Shit, more than two hours are up. We better get down there."

She opened her dazed eyes and grinned. "You go down. Tell them that I have to lie on my back a while. It's what the doctor told Mark and I to do to improve the chance of getting pregnant." She watched him get dressed. "Come here," she said beckoning me with her index finger.

I leaned over and kissed her. "I guess we will do this tomorrow."

"And the next day and the next day," she sighed.

******

Earlier, after we kissed during our second time and were resting, I told her my concerns that there was a chance that our spouses wouldn’t be comfortable with this for the whole two weeks. She said she, too, had similar thoughts. That’s when I let her in on the plan that I was thinking about. At first she seemed apprehensive, but after a while she agreed to it and gave an evil grin. That grin just told me the ground rules were out of the window and next day we would be fucking like bunnies.

*******

When I went downstairs I found both Becky and Mark sitting opposite to each other and Mark looked a bit uncomfortable when he saw me. I informed them that Jess was still upstairs, keeping her feet up to hold everthing inside for better chances.

What about tomorrow?" Becky asked. "You're supposed to do it every day."

I replied, “Why don’t you and Jess come over to our house tomorrow for lunch?" I asked Mark. "There something I need to talk to you guys about.”

I started to walk to the door when Mark jumped up and walked to me. I leaned back hoping he wasn't going to punch me, but felt his hands pulling me into a hug.

"Thank you brother," Mark said. "This isn't easy on any of us and I want you to know how much I appreciate what you are doing."

“Tell Jess we will see her tomorrow. Goodnight, Mark," Becky said, took my hand and walked outside.

*******

The next afternoon they arrived and once we had lunch we rested for a while. We were in the den when I turned to Mark and Becky and said, “Last night Jess and I talked for a while, and we both feel that it doesn’t seem fair to you guys that you both have to leave the house while your spouses are having sex.” They both started to say something when I raised my hand signaling them to remain silent and let me finish. Then Jess started from where I left off. “So, I suggest that we forget about the rules and have it in the old fashioned way. Before you both say something, let me finish. We both think that it’s only fair that you and Becky have sex with each other for the whole two weeks.”

Mark was stunned at what he had heard. First he looked at his wife, then at Becky who was looking at me with the same expression. “Let me get this straight and see if I understand what you are saying. You want that I should have sex with Becky, and Steve that you are fine with it.”

Becky looked at me said, "Honey are you sure about this?”

I looked at both of them and said, “Yes I’m absolutely sure. I know that how difficult this must be for both you and Mark, knowing that your spouses are having sex with each other. And also, we both kinda felt guilty that while we were having sex you were probably just sitting watching telly or talking, both trying to keep your minds off the same fact.”

“So, yes. If both of you feel comfortable enough with each other, Jess and I would like you two too have sex with each other. You can go to the master bedroom and talk about it and maybe kiss each other and see where it leads.”

Mark looked at Becky who managed to look back seriously. "I'm okay with it and you are probably right," he said. "If we all do it at the same time then there won't be any jealousy and no holding back."

When Mark and Becky got up and went upstairs, I had an inkling that they both had talked about it last night and maybe they were going to tell me and Jess the same thing. I turned to Jess and whispered “I think they talked and came up with a similar plan.” She looked at me and said that she doubted it. After ten minutes, we went upstairs and heard the tell-tale signs of fucking coming from the bedroom.

"It worked, though," Jess whispered.

Then I led her to the guest bedroom and started fucking the living daylights out of her. That’s how it went on for the next two weeks. Both the couples would have sex. One couple would be watching Mikey while the other couple had sex. Weekends we both would be screwing at the same time as my parents always have Mikey for the weekends.

******

Later on, Becky told me that on that first day Mark and she had kissed each other and had masturbated for each other, although they hadn’t looked at their private parts. She said that they were wondering how to approach Jess and me with the same idea and how we would react. But I had beaten them to the punch and suggested it first.

*******

Six weeks later Jess and Mark told us that Jess was now pregnant. Nine months later a beautiful angel who they named Paula was born. She looked so beautiful, a true angel. She was the exact copy of Jess except for one fact, she had my blue eyes.

The End
