I sat in my study trying to avoid an heart-attack. The cause of this was my wife. Not anything 
she had done but something she had asked me or rather told me.
It all started when we sat sipping a glass of wine Friday-night. Suddenly she turned to me.
"I spoke to Beth today."
"Oh. How was she?" I asked not to interested, her sister usually called my wife at least two 
times a week if my wife didn't call her.
"Not to good."
"So? Is she sick?"
"No. Not she, but apparently Ron is, no his not sick, it seems that he is unable to get Beth 
pregnant."
"Oh?" this time I was a little bit more interested.
"Now, you don't go around and hinting you are a 'better man' than he is just because I'm 
telling you this. Beth doesn't want him to know."
"She doesn't?"
"No. She think that she can cope with the problem by herself, with a little help from you and 
me."
"Us?"
"Yes. And I promised her that I would talk with you."
"You did?"
"Yes. But only if you promise not to tell Ron."
"Uh?"
"Yes. We don't want him to get upset."
"You don't?"
"No."
"I see," I said not knowing what she was talking about.
"Good."
"Uh?"
"I said 'good'."
"Yes. I heard that."
"Good."
"Uh?"
"Oh I give up!"
"You do?"
"Yes!"
"Good."
"You're hopeless. You really don't know what I'm talking about, are you?"
"Quit frankly - no."
"Oh I'll spell it out for you then. She want you to father her children."
"Me? Father? What children?"
"Hers and Ron's of course!"
"How can I father hers and Ron's children?"
"Oh I give up! Look down," she said.
I did that but didn't see anything but the carpet.
"Not there!"
"No?"
"No! What do you have that Ron doesn't have?"
"Uh? You?"
"Yes, but aside from that?"
"I - I - do I have...?"
"Yes. You have a functional... thing!"
"Oh!"
"Yes. Oh!"
"So?"
"Really Joseph," she never calls me Joseph but when she is irritated on me for something or 
other and I've seen to that she rarely is. I hate my name. I prefer Joe. It's much more... 
manly and handy. "Sometimes you really gets on my nerves!"
"I do?"
"Yes. Must I spell everything out in the tiniest molluscular detail?"
"Molluscular? That's not..."
"Never mind! She want's you to fuck a child in her!"
"Oh my god!"
"At last! Really Joe. Sometimes I wish that... Yes. And I agreed."
"You did?"
"Don't you dare start that again!" she warned me, not that I had the slightest idea what she 
was talking about now either.
"No, dear, I wont."
"Good. Yes. We have agreed that Mondays and Thursdays are the days that you can... service 
her."
"They are? I can?"
"Yes. I don't want this to interfere with our sex-life."
"Of course not, dear."
"So every Monday and Thursday Beth will come over after dinner and stay till nine o'clock. 
That will give you plenty of time making the child, wont it?"
"Yes, dear."
"Good. Agreed then."
"What?"
"Joseph!"
At this point I stood and staggered into my study. I only wished that I had some 
nitroglycerin-tablets it felt as if I needed some.
I still wasn't sure that I had heard my wife right. She wanted, really wanted, me to fuck her 
own sister? And not only that, fuck her without any contraceptives? I slumped down on my chair 
and just sat there staring at nothing. After a while I had gathered enough strength to stagger 
up and pour myself a stiff whisky and with shaking hands I lifted it to my lips and took a big 
gulp.
The more my wife's words started to seep into my numb mind the more did I focus my inner 
imaginer at Beth.
She's a fox. If possible even better looking than my wife. You can tell that they are sisters 
as usually when it comes to siblings. The same slender bodies, the same dark-blonde hair, 
straight noses and full lips. Rather small breasts, slim waist, long legs and a great ass. 
Well, she looked almost as my wife. Just as beautiful, just as... adorable. Just the thought 
of her and my wife naked made my cock tilt a little and harden a little.
At last my wife's words started to seep down. I looked down and suddenly realized what my wife 
had meant when she asked me to look down!
I have a bigger cock then Ron! That's why she wanted, they wan... no, that wasn't the reason. 
But something about my hardening cock got me to think. If it got hard enough I had to go in to 
my wife and fuck her. Aha! That was it! I could make babies! How did they know? I've never 
made any, to my knowledge.
Never mind. They wanted me to fuck Beth, so... At this point I just gave the whole thing up 
and I didn't think about it for almost two days, and then suddenly Beth was there.
I sat in my study doing what I do there when I heard my wife call.
"Joe, darling! Beth's here now!"
"So?" I thought. "Why call..."
I scrambled to my feet and hurried over to the living-room. Yes. There she was.
"Hi Joe," she said in a little shy voice I never heard her use before.
"Oh, hi Beth. Nice to see you."
"You too."
"Yes. It's time," my wife said prosaicly.
"Time?" of course it was me asking.
"Yes. Time. You haven't forgotten what we talked about the other day, have you?"
"No, dear."
"Good. You may service her in our bed. I've put fresh sheets on," she said to her sister. "I 
would estimate that Joe will need, oh what, say thirty minutes..."
"Thirty minutes?!" Beth said surprised.
"Yes dear. That the average time we..." at this point my wife blushed. "Yes. Thirty minutes. 
Don't you think so dear?" she asked me.
"Oh. I don't know."
"No, I didn't think you would. It was a rhetorical question."
Sometimes I suspect that she thinks that I'm a little, well week in the head. But let me 
assure you I am not. It's just that I never seems to know what she talks about.
"But - but I thought we could do it, well, just for a few minutes. I don't want to cheat on 
Ron you know."
"Uh?" me.
"No dear. You wont. And you aren't. You're doing it for the both of you."
"Oh yes. I do want to be a mother! Oh Joe. I would be so graceful if you help me. Us, I mean."
"My pleasure," I assured her.
"Yes, I bet," I heard my wife mumble.
What dear?"
"Nothing. I'll have a cup of coffee for you in about half an hour then."
"Yes. Thanks," Beth said a little hesitantly.
My wife turned and went out in the kitchen and Beth looked at me and smiled a weak smile.
"will you..."
"Yes."
I turned the other way and lead her to our bedroom. Olive had folded the blanket to one side 
so you could see the fresh sheets. I closed the door behind us and when it slammed a little 
Beth jumped more than a little.
I looked at her and she looked at me, and the bed.
"Should I... take of my... undies?" she asked me embarrassed.
"Well if we're going to do this, we are going to do it the right way," suddenly realizing that 
I called the shots. "You have to make love to make babies, unless you don't want it from a 
tube, that is. Do you?"
"Oh no. No! I couldn't. Ron would..." her voice trailed off.
"Yes. Then we'll have to do it the proper way. I want you... nude! And I'll be nude. And then 
we... well have foreplay. Did you know why a woman have orgasm?" I asked.
"Of course! To make us feel good."
"No, no. When a woman have an orgasm her cervix dips down and sort of lap up the sperm 
deposited by the man. So you see you have to reach a climax too, not just a casual... fuck!"
She blushed if possible even more at this.
"Oh. I-I thought..." she began. "That you could... could just put it in and..."
"Oh you heard Olive. Thirty minutes. That's the least it takes and that's only if I'm hot and 
ready, so-o..."
She actually blushed as she was thinking about what I had said and then to my great delight 
she began to undress. First the blouse, revealing her white bra containing a pair of rather 
small breasts, then off came the skirt, at this I threw off my own clothes and stood naked 
waiting for her to get undressed. My cock was already thickening and swelling into full 
erection and while I looked at her while she reached behind her and unsnapped the bra, pushing 
down her panties and bending over at the last moment to get them free from her feet and 
presenting me a well rounded ass. When she stood I caught her glance at my by now stiff 
member.
"So?" I asked when I noticed her glance. "Is this the biggest you've ever seen?"
She nodded and blushed even deeper, not that my cock is bigger than the average cock but I was 
proud of it since it's my only baby-making equipment.
I took her in my arms and pressed her naked body against mine her small tits bore into my 
chest and my cock rubbed into her flat and soft belly. She hesitated a little when she 
realized that I wanted to kiss her, but then our lips met and my tongue didn't reached any 
resistance when it invaded her mouth. Still with my mouth on hers I lowered her down on the 
bed with her legs open and hanging over the side.
I looked down at her body and her blush returned as she felt my eyes on her naked form and she 
could hardly face me when I so openly ogled her body. I bend down and kissed pink nipples who 
stiffened at once when they felt my lips surround them.
My hand strayed down to her cunt and she moaned when I made contact with her clit and played 
lightly with it.
Despite her earlier words she was wet down there and her cunt gave a slurping sound when I 
stuck my finger in it and wiggled it a little.
"Oh," she whispered and when I again wanted to kiss her tongue eagerly met mine.
Without any preliminaries I went down and placed my lips against her wet pussy.
"Oh my god," she moaned and put her hands on my head and pressed my face tighter onto her 
cunt.
I licked and sucked and whipped her clit with my tongue. Her hips shook and raised over the 
bed and when I lifted my head and looked at her I could see that she was hot. Her mouth a 
little open, eyes closed and moans of pleasure escaping her and a moan of disappointment when 
her pussy was abandoned by my lips.
"You love having your pussy licked, don't you dear?" I asked. "Getting you wet and open for a 
good fucking. Tell me that you want me to fuck you."
"Oh I do, I do," she moaned. "Put it in me, make me a baby. Fuck me. Fuck me!"
I pointed the head of my cock at her entrance and pushed and i slipped straight in to the hilt 
in a juicy pussy.
We both groaned as we humped, fucked each other with vigour. And then we came the both of us 
and it hadn't taken the promised half hour but only a mere ten minutes. We rolled apart, 
satisfied for the moment and I kissed her and when her hand found its way down to my cock and 
caressed it it again started to swell and she looked at me with lust in her eyes.
"Again?" she whispered. "Will you fuck me again?"
"Yes, honey."
This time we fucked in a slow during which she orgasmed almost constantly.
"I think that if what you said before is true, I must be pregnant by now. I've never cummed 
this many time before," she giggled when I finally shot my second load in her and fell down on 
the bed beside her.
At this point there was a knock on the door and my wife stuck her head in.
"At last!" she said. "I've had coffee ready for at least half an hour!"
"Huh?" both Beth and I said.
