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.
