A newly married lesbian couple decided to have a baby. They turn to one of their brothers to impregnate the other. Afterwards the brother begins to have feelings for the woman carrying his baby. While his sister and his wife begin to bond as well.
 
Pregnancy

I like the pregnancy aspect of this story. However, I would like it more if the sister's wife was more of a surrogate instead of just using the guy as a sperm donor.
 
You probably won't like the way I handled something like that toward the end of The Book of Ruth: Doing Ruth Pt. 02. Randy's ruthless sister Jill (who's been screwing him for years) and her lover Gabrielle decide they both want to be impregnated by him. So they tie him down, drug him nicely, and essentially rape him. He's not real happy about that, eh?
 
How about this scenario:

A lesbian couple (Tina & Jo) want to have a kid. They try a couple rounds of artificial insemination to try to get Jo pregnant. Unfortunately, Jo did not get preggers. Each round cost 10 grand & they can't afford to go another round. Tina suggests an idea to Jo about going the old school route. Jo is terrified at the prospect since she has never been with a man before but her biological clock is ringing. Jo agrees but she wants Tina to literally hold her hand while she is getting screwed to which Tina begrudgingly agrees to.

The next thing was finding a guy that would be up for it. They went through the list of every guy that they knew when Jo had an epiphany:

"Alex!!!"

"My little brother Alex?" Tina replied.

"Yeah...it's perfect! He idolizes you plus the baby would technically have both of our DNA."

"Jo, he just turned eighteen. I'm almost positive that he's still a virgin. Also, it would be pretty fucked up since you want me to hold your hand while he bones you."

"I admit that it's not perfect. He is kinda scrawny but he's a straight-A student so that's a genetic plus. He will probably pop his top in minute or two which is a bonus for me! I don't think it will be that hard to get him to say yes. I'm fucking hot and your little brother isn't really subtle about sneaking peaks at me whenever he gets the chance. It will be like Christmas and his Birthday wrapped up into little blonde me."

They were not shocked when Alex agreed. (Alex had repeatedly fantasized about fucking Jo's smoking hot body ever since his big sister started dating her).

They decided that when Jo was most fertile, they would let Alex fuck her as many times as he could over the course of three or four days. Hopefully, one of his boys will hit the target.

The day came and all three of them were in the bedroom. Alex & Jo nervously began undressing and the girls were shocked to find out that Alex may be scrawny, but he was packing a cannon in his pants. Jo was even more intimidated by the fact that the first guy to fuck her was going to be doing it with a dick that a pornstar would be envious of. His sister shamefully couldn't take her eyes off her little brother's erect cock. She was mentally comparing it to the strap-on that Jo fucks her with and coming to the conclusion that his dick was longer and thicker than her favorite fuck toy.

All three got on the bed. First Jo, who laid down on the center of the bed. Then Tina sat next to her and held Jo's hand as promised. Finally, Alex crawled onto the bed and knelt between Jo's spread legs. Alex didn't know where to look. His eyes bounced around from Jo's amazing natural breasts, up to her beautiful face, down to her completely waxed pussy, and then to her sister.

Tina handed her little brother a bottle of lube. For a moment, his naiveté shown through. Tina explained to slather that on his rod so he wouldn't kill her girlfriend. He did as he was told and then got into fucking position. Jo gasped and tightly squeezed Tina's hand as Alex's mushroom head pushed through Jo's perfect cameltoe.

"Be gentle Alex, I've never had anything that big or real in me before."

Jo couldn't believe the intense feelings that were generating in her loins. His cock felt so different from the dildos and other toys that she was used to. The heat from his manhood alone made her realize why women like the real thing. She also couldn't believe that Tina's little brother hasn't blown his load yet. (What Tina & Jo didn't know was that Alex rubbed one out before coming over. He wanted to make the most out of the situation).

As Tina watched her little brother fuck her busty blonde girlfriend, she noticed two things. She observed the shocked look on her girlfriend's face and realized that Jo was really enjoying getting fucked by an actual dick. Secondly, Tina realized that she was incredibly turned on by what she was watching. Her nipples were as hard as eraser nubs as they pressed against her tight white t-shirt. A wet spot had already formed on her blue jean shorts.

Jo wrapped her legs tightly around Alex as she felt her orgasm approach. She screamed out to Tina:

"I can't fucking believe it but your little brother is going to make me cum...HARD!"

When Alex heard that, he began to jackhammer his massive cock until Jo's toe-curling orgasm arrived. He paused for a moment as her body tightly convulsed against his. When she finished Jo asked if he had cum too and his response was:

"Not yet. Do you mind if you could be on top for a bit?"

Jo got into cowgirl position and began bouncing up and down on his thick cock like she was riding a mechanical bull. Alex was in heaven as he watched Jo's supple breasts bouncing up and down as she tightly held on to Tina's hand. He then noticed that his big sister had a patina of sweat on her face as she stared at his cock disappearing into her girlfriend's tight pussy. Her chest was heaving like Jo's bosom. He realized that she was enjoying the show. He couldn't believe it when he just spouted:

"Tina, kiss her."

His big sister seemed to snap out of it and did as her little brother asked. Not only did she do as he asked but she began to rub her girlfriend's clit as well. Moments later, Jo came all over his cock again. He watched as splash of fluids hit his lower torso. Alex felt her big sister's hand occasionally rub against his shaft which sent a shiver up his spine. He never thought about his sister in a sexual way before but he could not deny the fact that this may be the hottest thing he has ever witnessed. That touch ended up putting Alex over the top:

"Ummm guys...I think I'm going to CUMMMM!!!!"

Alex could feel Jo's pussy tighten like a vise as blast after blast of cum filled her up. She collapsed on top of him, still clutching Tina's hand.


Their continued attempts to conceive get hotter and more incestuous as Tina gets into the action as well. First it's pleasuring Jo while her little brother fucks her girlfriend. Eventually it escalates to the point where Alex fucks his big sister as well in an epic threesome.

I think this is a good angle for the 'donor' idea, even if I'm not so interested in the incest category. I've thought about this topic for a few story ideas, but it's never worked out well for me. Every time I get started on this, I keep switching between different story lines, and my muse kicks me in the nose, telling me that this isn't something I should do.

Here's a few of the most common threads that have gone through my mind:

--- Primary Story Theme Starter:
Guy1 and his twin brother Guy2 are both happily married to a set of twin sisters, and while neither sets are identical twins, they all look alike.

Guy1 and Girl1 have two children, and both of these children are rising stars in their elementary classes, and Girl2 is becoming increasingly jealous; she wants awesome kids like these, and she knows the blood-line they all share is a recipe for success. She knows that Girl1 had her tubes tied after the c-section of her last child, and Guy2 had a vasectomy years ago, so as Girl2 feels her biological clock ticking, she knows it would be impossible for her to have a child if things progress normally.

Twist 1:
Girl2 connives with Guy2 to get his twin brother to sleep with her a few times a week during her fertile periods. Guy1 would be an unknowing partner to this scheme, and once pregnant, Girl2 would say they did it via invitro.

Twist 2:
Again with the excuse of 'invitro', Girl2 and Girl1 conspire to switch husbands during a late night of drinking one weekend. They only do this in the hopes that Guy1 will impregnate Girl2. The ladies both enjoy this experience, so they make it a plan to do it every weekend until Girl2 is fertilized. Since it takes a while for the tests to come back positive, the couples swap for several weeks after Girl2 is pregnant.
----Question: Do the guys ever figure this out? Do they realize that the amount of alcohol the wives make them drink to get to this point is excessive and swap out the vodka for water? Only the guys are drinking since the ladies don't want the alcohol to potentially harm the baby.

Twist 3:
Guy1&2 and Girl1&2 all know that Girl2 wants a baby, and as much as she wants Guy2 to be the father, it can't physically happen. With everyone's full consent, Guy1 and Girl2 spend an hour denting the mattress twice a day while Girl2 is on her fertile cycle.
----To make it fair physically, they all know that the unmarried couple is enjoying it, so do Girl1 and Guy2 spend time together as well?

Twist 4:
Girl2 begs Guy1 for months, asking for his help to make her pregnant. After the third session with the invitro doctors, and over $30k spent, Girl2 knows this can't go on for long. In a moment of weakness, Guy1 agrees as Girl2 flirts with him non-stop. After the deed, he is regretful, but Girl2 whips him into consent, saying that unless he does this with her every other day, she will show Girl1 the video she took of their first time. Guy1 likes the sex but hates the cheating and deception, and as much as he wants Girl2 to carry his child, he also hopes that she doesn't conceive so he can keep his access between her legs.
 
A newly married lesbian couple decided to have a baby. They turn to one of their brothers to impregnate the other.
Players: Jill and her wife Lisa; Jill's brother Jim and his wife Kendra. Possibilities here, with and without incest:

* Men terrify-disgust Lisa. Jim isn't the nicest guy. Their coupling is disturbing.
* Men terrify-disgust Lisa. Jim IS the nicest guy. Their coupling is tentative.
* Lisa was always curious about men and has rather liked Jim. Jill gets jealous.
* Lisa was always curious about men but never liked Jim. Jill gets persuasive.
* Lisa and Jill have always liked Jim and vice-versa. The 3-way is inevitable.
* Nervous Lisa demands a blind gloryhole impregnation. Jill slips in somehow.
* Nervous Lisa is reassured by Kendra. They bond. Does Kendra go lez or bi?

Afterwards the brother begins to have feelings for the woman carrying his baby. While his sister and his wife begin to bond as well.
This could delve into non-incest polyamory: Jim sleeps with Kendra and Lisa, Jill sleeps with Kendra and Lisa, and Lisa and Kendra sleep with everybody. Can Jill stay away from Jim? Meanwhile the players' families wonder a bit about the relationships. Resolution could be romantic or tragic or comedic, your choice.
 
Sorry to halfway hijack your thread but the title of your post gave me an idea for a story. It revolves around a heterosexual couple who cannot conceive a child and it is decided that the husband's brother will attempt to impregnate his sister in law (so the child will actually have some of the husband's genes and features). Nothing fancy but the story revolves around their sexual encounter (or encounters) and the fact that this brother has lusted after his sister in law for some time and his very good fortune is like winning the lottery.

No worries, you're not hijacking anything. Regardless of the relationship, tell us your ideas and let your muse run with it. There have been a few ideas tossed around, and this one is as workable as the next.

Now that you've written a quick blurb, how does the rest of the story turn out?
 
Sorry. I don't have as much time as I used to. Let's say that John and Jane Doe are married and have been wanting a child real bad. It is discovered that John cannot father children. Both have been wanting another male for a threesome and Jane had been suggesting John's twin brother, Joe. John had alwwys been against this matchup but now Joe actually seems like the perfect choice to father his child. In the meantime, Joe has always been jealous of his brother for landing such a hot babe and has secretly fantasized for along time about fucking his sister in law. John and Jane approach him about helping them out with their problem and he can't believe his good fortune. They meet on a regular basis to insure insemination. I don't really see the ending but see descriptions of several encounters.
 
My story idea has been bothering me ever since I thought of it because it seemed to lack a certain pizazz or wow element. After thinking on it overnight the missing element finally came to me. The twin brother Joe has a wife of his own (Jenny). Joe is a loyal and faithful husband and tells Jenny the situation. She doesn't like the idea but she is a practical woman who can see the logic and common sense in using her husband's identical genetic makeup to father this child so she reluctantly agrees to let Joe repeatedly fuck his sister in-law until the child is conceived. They have the threesome a couple of times but Jenny gets more and more uncomfortable with the situation until she realizes that the only fair thing to do is to turn the threesome into a foursome where she could fuck John as much as she wants without having to worry about getting pregnant herself. What a perfect situation!

To spice it up even more John and Jane are into BDSM but the others have been vanilla up to now. BDSM is slowly introduced into their lives and they're loving it. Bisexual play could also be involved. This would be a great set up for a chapter series.

What if the wife that wants to get pregnant quickly realizes that her husband's twin brother is a Jedi Master of fucking. She has so many toe-curling orgasms that she loses count. Her husband is a two minute man who seems to only prefer the missionary position.

She quickly conceives but craves her brother-in-law's fuck skills. She lies to her husband in order to keep fucking the brother-in-law. She manages to get another two rounds since she's not showing but her husband starts to realize what's going on when she begins to show in the third month. The wife doesn't realize that her husband discovers that he has a cuckold fantasy. He set up a GoPro camera & had been watching her brother rock his wife's world and been getting sexually gratified by it.
 
How about the girl in question (The one who wants to be pregnant) eventually starts taking "The Pill" to stop herself from getting pregnant and keep up the regular fucking sessions with her wife's brother?
 
Yeah. That's possible. First it was set up to achieve pregancy but the twin brother is such a good fuck while her own husband isn't that she realizes she just can't go back to the way it was. She could even decide to turn her husband into a cuck.

I think this is a good idea for a story. I don't like the part about his sister getting close to his wife. It's just not realistic in my taste. If his wife has never been a lesbian up until this point, why would she suddenly be one now. It's just a pet peeve of mine when people try to suddenly switch sexuality, just for the convenience of the story.

I personally like everything about this, except the cuckold aspect. I would really like to see some stories about cheating without the aspect of the other spouse enjoying it. My twist on this would be that the husband would have a very real and hurt reaction to finding out wife's secret and would try and find a way to remedy the situation.
 
I wrote a story much like what was originally suggested. The narrator's sister and her wife ask him to impregnate the wife (again, want to keep DNA). The narrator says he'll do it, on the condition that he gets to watch them make love first. The brother and sister don't have any actual sexual contact, by mutual agreement. Subsequent attempts are done without the sister.

Mine had an unusual twist. Unbeknownst to the narrator, his sister was also working with an unnamed relative of the wife. The narrator sires a child with the wife, who gives birth a month after the sister does.
