This was a concept that initiated over a decade ago online where the author (dawn_f) wrote about single mom's named Sarah and Karen who were living together and had a point of contention about one breastfeeding the other's infant which led to them preparing to titfight. It never got to the actual fight and was abandoned. Another author came along and started rewriting it years later, but also never finished. I've taken the names of the women, and the inciting incident about breastfeeding, and written a very different story around it.
Hope you enjoy it.
Breast Feeding
Part 1
Matt and Jake were half-brothers from a large family, both self-employed and doing reasonably well, who had married in their late 20s. Matt's wife, Karen, worked in health care. She was a pretty shoulder length brunette who did crossfit and jiu jitsu a few days a week because she was afraid her curves would lead to her getting fat if she didn't work out. She even did a little kickboxing and was a natural athlete but her build limited how far she could go in any sports. Matt compared her to a shorter, sexier version of Gina Carano when she had filled out after her fighting days.
Jake's wife, Sarah, was an event planner. She was a pretty long haired blonde who jogged a bit but otherwise was proud of her curves. She knew there might be a time where she would have to focus more on keeping her body from getting out of control, but for the time being she enjoyed being right on that edge of being fat that the kids these days called thick. Jake considered his wife to be a taller, sexier version of Tiktok influencer Anelia Verbin, a.k.a. yellz0.
Matt and Jake were both boob men and many playful arguments had arisen between the two when comparing their significant others. Matt was certain that Karen's slightly smaller pair was firmer, due to her working out and taking better care of her body, and would wear out Sarah's bigger rack and squash it flat. Jake obviously disagreed, telling his bro that there was no workout that would make the brunette's smaller pair stand up to his blonde wife's bigger globes.
The couples got together fairly often, leading the men to compare their wives even more. One that kept their fantasies going for a while was a night that ended up in Matt and Karen's hot tub with both women sporting two piece bathing suits that flattered their bodies. Matt begrudgingly admitted that Sarah's bigger tits were closer in firmness to Karen's than he originally thought while Jake reluctantly noticed that Karen's smaller boobs were closer in size to his wife's own pair than had believed they would be.
Karen and Sarah were not unaware of the fetish each husband had. They both had indulged in comparisons with women they saw in public and some role playing in bed as they described the titfights they would have with a variety of potential opponents. Each read some of their husbands favorite stories and watched videos on the sites their men had frequented to get their fix of female competition, mostly focused on no hands titfights. While neither man had broached the idea of the other's wife with their own, neither woman was oblivious to their obvious similarities. When they saw their husbands eyes darting back and forth between both pairs of tits in the hot tub, Sarah and Karen began to take closer notice of their counterpart.
Before anything came of it, something much more interesting happened. Both women got pregnant and gave birth to girls within a few short weeks of each other. Sarah's body finally pushed over that edge from thick to carrying more fat than she wanted while Karen's muscle disappeared behind her own layer of extra meat on the bones. While both wanted to get back to their pre-pregnancy look, neither was upset about the transformation of their boobs. Sarah's big rack had gone up a full cup size, at least, without any more sagging at all even when fully loaded with milk. Karen's pair had also grown quite a bit and, even though they didn't look or feel quite as firm with the extra volume, both she and Matt secretly thought they had caught up to Jake's wife's pair in size.
Every other week one of the couples would drop their little one off with the other, just so they could get some husband and wife time alone and refresh a bit from the frantic nature of being first time parents with an infant. This particular week in December saw Matt and Karen drop off little Allie with Jake and Sarah. After a relaxing dinner at a fast casual chain they returned to pick up their daughter.
As Karen began putting her in the car seat, she noticed that the bottle she had pumped ahead of time was still full. "Did Allie not eat?" Jake responded, "We tried giving her the bottle but she just wouldn't take it this time. It's okay though, Sarah fed her." Karen and Matt's heads both turned to the blonde wife standing off to the side as she blushed and lowered her head, "I had enough to take care of her. It was no problem, really." Matt hesitated for a moment before he responded with a simple, "Oh, okay, thanks," and then the couples chatted for another minute or two until Allie was fully in her seat and everything was ready to go.
"Did you see that!" Karen was fuming as they turned the first corner leaving Jake and Sarah's house.
"See what, honey," Matt responded as he tried to not focus on the image his mind had created of the blonde pulling out her big tit and feeding both girls at once.
"Don't act like you didn't fucking see it. She smiled while she was pretending to blush and put her arm under her fat tits to push them up while she was acting like she didn't have any choice but feed Allie herself instead of using the bottle. She knew exactly what she was doing. I bet she does that same fantasy shit for Jake that I do for you and she wanted to show me up in front of both of you."
"Come on honey," Matt said as they neared their home across town, "I'm sure it was completely innocent." "Innocent!" Karen yelled at her husband.
"There's no way Allie wouldn't take a bottle of my milk. She did that on purpose. She better not do it again if she knows what's best for her."
Matt felt his cock jump a bit at that last comment and barely got out a whisper, "What if she does?"
"You know those milking titfights between mom's that you like to read about so much honey?" Karen said as her anger subsided just enough to notice her husband's arousal, "If your brother's cow-titted wife ever feeds my baby with her fat, flabby tits again then you're going to see a real titfight and I'm going to milk her dry with my better tits."
Part 2
Jake looked at his wife with a sly smile. It was true that Allie was being fussy about the bottle before she eventually drank from it. While Sarah was feeding Kaycee and Jake was trying to feed Allie, he joked that maybe his blonde boob goddess should pop her other big tit out and let his sister-in-law's child feed on it. Sarah rebuffed the idea, knowing how awkward it would be if Matt and Karen found out, and they continued as normal. As the kids finished, Jake blurted out another comment that should have gone nowhere.
