Judy Hopps had been laying in bed all day. Her left hand slowly stroked over her engorged belly as she used her right to stroke her sex. Judy had never given a great deal of thought to motherhood, it simply was of no concern to her if she would ever have children. That had changed a few years into her time with ZPD and her marriage to Nick. If biology hadn’t gotten in the way the kits in her womb would be his. Lacking the funding or time to really get fertilized in a lab she and Nick had gone looking for another couple with the same problem. It took a few days of searching and a few awkward conversations but Nick found John O'Hare and his lovely wife Betsy Nights. Betsy was like Nick, the older of the pair and the one most concerned with having a child. Judy had never seen a vixen like her before with her deep black and silvery white fur. She had the most dazzling golden eyes, like seeing the full moon on a dark lake. Betsy was something of a country gal herself having moved to the city in search of romance and having found her love in a coffee shop. John was a businessman, he dressed slick and clean and his square rimmed glasses made him look nearly like a stereotype. The insurance salesman was the less spontaneous of the pair having to plan everything methodically. Judy had been slightly put off when she saw his deep red eyes and white fur. She’d heard no end of rumors about the kinds of illnesses that rabbits with those traits could have. He had rather calmly explained though that he did not have any such conditions. The two couples had been utterly smitten with each other by the time they arranged to actually meet. Judy had been nervous about the meeting for weeks having by that point only spoken to them over cell phone or video call. Even as she was taking her guests hand and leading them into the bedroom she shared with Nick she felt the encounter was unreal. Nick being far bolder then she was already stripped naked and waiting with his cock barely hidden beneath a towel. Later he would claim it was because he had just showered when they arrived but Judy knew better. At the sight of her husband laying in her bed preparing to have sex with another woman (even with her permission) Judy had turned back out of the room forgetting that she still had ahold of John’s hand. The vixen closed the door behind her As Judy came to a stop in front of the couch heart pounding. It was only as John turned her to face him that she remembered her grasp. John confessed he wasn’t thrilled to see his beloved with another man but that they all had agreed to this so they might as well go through with it. Judy recalled feeling more nervous and self conscious about her body then the first time she had sex as she stripped out of her clothes before John. She was pleased to see his arousal as he joined her in standing nude. Judy’s anxieties faded into the background as she sat herself on the couch and spread her legs. Her anticipation had mounted until his cock slipped into her and all at once she was in her comfort zone once more. It didn’t matter that his cock was thinner if longer than Nicks. It didn’t matter that John preferred quick shallow thrusts to the long slow strokes Nick did. It didn’t matter that this wasn’t her husband, it was just animal pleasure between them. They had as a group agreed there would be no kissing, no fondling, no sex outside the type that would lead to children. Neither Judy or John could keep to that agreement though. Their lips met as his fingers slid over her chest tickling her nipples. John came in her pussy and kept going in true rabbit style. She wrapped her legs around his waist as she felt his seed pump into her belly. Her own orgasms started after and as Nick had said she was not one to cum quietly. She moaned loudly only muffled by John's lips as her body pleaded for more of the pleasure he was giving. In the background she was aware she could hear Betsy and Nick going at it. Nick was a bit chatty in the sack, Judy could hear him talking about how soft and warm she was and how he was going to pump her full of kits. Betsy it turned out was equally chatty, encouraging Nick to make her cunt an absolute mess and to hold her tighter. Judy knew that if she could hear that so could John and if anything both rabbits found the sounds of their lovers engaging so to be a massive turn on. Judy moaned as she came again hearing Betsy beg to take Nick’s knot. John flooded her womb with seed once more as Judy heard Nick compliment Betsy’s husband on his hard work. Neither of she or betsy got pregnant that night but from that point on their meetings were much less awkward. They ate dinner together discussing the challenges of being an interspecies couple and after Betsy and John left for the evening Nick and Judy spent an hour making out on the couch with Nick confessing that he hadn’t kept to the no kissing rule. Judy had come clean as well stating she couldn’t be mad at him. Their second time together was at Betsy and John’s home. Judy stripped naked the moment she was inside the doors and asked Betsy to show her the bedroom. Betsy stripped down once they were in the bedroom and it was plain to both women they were eagerly awaiting the night's activities. John and Nick entered the room already naked. Judy and Betsy laid out on the bed and eagerly watched their husbands climb on to the bed. The two men wished the other luck and set to work. Judy was shocked at how much more erotic it all felt to be laying next to the vixen her husband was fucking and to know that he was watching her be claimed by another man. It was a bit of a surprise during the fucking when Betsy turned to her and pulled her into a kiss. A surprise she hoped she returned at least a little when Judy took hold of the vixen’s head and not only held the kiss but deepened it. For the rest of the evening the two ladies held hands singing the praises of the other husband. It was somewhere around her third orgasm that night that Judy realized she was in love with this other couple. Later that evening when she and Nick were showering before they left she shared her feelings with Nick she was more than a little pleased when he admitted much the same. It would actually be on their third meeting that they would learn Betsy and John felt the same. Their meetup to breed was a little different this time with the two men taking seats in chairs facing each other so they could watch as their wives rode the other’s cock. It started as John complimenting Nick for taking such good care of his wife. A compliment that Nick returned and added that it was a pleasure to watch. Betsy had enthusiastically agreed that she loved watching Judy’s eyes go crossed when she came. Which prompted Judy to observe how Betsy’s whimpers of pleasure were the second most erotic sound the vixen made, the first being the yip she let out as Nick tied with her. John apologized as he confessed to falling in love with Judy and Betsy moaned as she professed her own love of Nick. Judy grinned wide looking at Nick before confessing her love as well. Nick naturally enough informed them of his romantic feelings. They ate dinner that night all aglow with this new status quo. They discussed pooling their funds and purchasing a larger house for a combined family. They agreed that the old rules were out but that they should avoid sex unless they were trying for children. It took another week of meeting up before they found a house. Just in time though as Betsy’s test had finally come back positive. Judy was just a little bit jealous but that only lasted one more evening before she learned of her own impending motherhood. Despite Betsy and Judy both being pregnant now the group's love life hadn’t slowed any, just shifted focus. Oral sex was a new step for them and Judy wasn’t sure whether she had had more fun educating Betsy on how to suck Nick off or being taught by Betsy how to use her mouth on John. They were still experimenting with their group dynamics so there was some variation. Judy found that while watching Betsy sucking off both their husbands made her cum without even touching herself Betsy found it just made her want to join in. Nick enjoyed licking the girls' cunnies till they squealed with delight but John found that cunnilingus just left him with a sore jaw and a raging boner. All four of them found that mutual oral sex was fantastic though some pairing were less likely to cause cramping. Judy and John were about the same height and so were Betsy and Nick. However, the realization that it was possible for all four of them to have oral sex if they laid just so on their new bed was a genuine eureka moment. Anal sex was not Judy’s cup of tea at least not with Nick his impulse to try and tie her was just a little too strong and a little too rough. John was better but tended to go too deep and too fast for her liking. She did however not mind in the slightest being laid out between Nick and John with one stuffing her throat and the other pounding her ass. Betsy on the other hand loved it in her ass she had some truly intense orgasms when Nick’s knot was wedged deep inside her or John was doing his best to break her hips. As her breasts filled out and her belly rounded Judy had become more and more enamored with Betsy herself. A feeling that was thankfully returned, neither of them had been particularly interested in girls until now but then neither of them had expected to be sharing their husbands either. Judy loved nothing more than to pull her vixen’s lips onto hers and then feel Betsy’s digits slide up her thigh. The pair liked to sit in bed stroking each other's pussy moaning about how horny their pregnancies were making them. Once or twice Nick or John or both would stumble into the scene and provide something for them to play with. Judy loved sharing their husband's cock. As their pregnancies advanced the boys got hornier and hornier. Apparently the sight of rounded bellies turned them on like they could have never guessed. They were flattered by the attention and their boys pumping their shafts to the sight of them was very affirming… at first. There came a point where Betsy and Judy were just done even looking at their hubbies. During this stretch Nick and John developed an appreciation for what they could do for one another. Betsy and Judy had come home from the doctors office to find Nick in his favorite chair with his knot firmly tied inside John's ass. The fox was cumming hard and thanks to a friendly paw so was the rabbit the pair didn’t even notice their wives had returned thanks to being engrossed in a kiss. After that it wasn’t unusual to find one of them sucking the other off or being taken for a ride. Judy had learned from Nick that he enjoyed John plowing his ass as much as he did stuffing the rabbit full himself. Judy creamed herself to thoughts of her lover just as Nick slammed the door open. “Hosptalbetsy kitsoon!” he blurted out as he grabbed the pre-packed bags and bolted from the door. It took Judy a second to realize what he had said and what it meant. She scrambled to get dressed and out the door. It was only in the car when the cramp hit that she realized she was not going to be able to see Betsy giving birth. --- Overnight the household gained eight new members. Nick and Betsy had three healthy kits, two boys and one girl. Judy and John had five kits: Three girls and two boys. It took a bit of finagling to get them all in the same room and then the new grandparents had shown up. Judy sat looking at the family of her own making and the joy that it brought to Nick’s mother and John and Betsy’s families along with her own. She wondered idly when would be a good time to ask Nick about having more children. “So Judy, when do we think we want more?” Betsy asked with a grin and twinkle in her eyes. “Hmm, maybe next month?” The assembled family laughed but Nick and John grinned at one another knowing their wives were very serious.
