Setsuko is about ready to pop...

I could always tell when Kenji returned home, even if the earth underfoot hadn't reverberated from his gigantic footfalls all the kids calling out and laughing gave it away. The whole town loved their big friendly giant and he was especially popular with the kids. He never got tired of giving rides or playing games with them. He truly was everything I’d ever hoped to find in a man to be the father of my children, even if mother didn’t approve.

Well, she didn’t really disapprove of him so much as the fact that I’d agreed to be one of his two wives. She always got perturbed that he had also married Natsumi, claiming their kids would be freaks for some reason, but refused to talk about it whenever I pressed. I thought she was just jealous that a woman her own age had gone and remarried, much less bore that man several children. Or maybe it was she was defensive of my status as a sister-wife. She always said I was good enough to have any man I wanted, but if not the strongest and bravest man I’d ever known he was definitely the most potent.

I rubbed at my swollen belly, feeling the stir of a still unknown number of babies in my well-stretched uterus, and tried to identify again how many might be within me this time. After that first encounter, we tried to back to our normal lives. While I knew even then that I loved Kenji I’d stupidly let my mother convince me it would never work out. She said he was too big and could never be the right man for me, but before the month was up I knew his seed had taken hold inside me.

After that, I went to the new barnlike house he’d been building for himself and proposed to him on the spot. He was so cute and shy, apologizing for saddling me with a child. I tried to make him understand, even make him happy every night for a week just as we had on that fateful day, but I couldn’t get him to cum again by myself. That is when I went to talk with Natsumi and found her puking her guts out and cradling a slightly swollen belly just as I was. That was when I knew fate intended all three of us to be a family and a growing one at that.

It took a lot of convincing to get her to come to move in with us, and they spent a lot of time talking about things between them very seriously, but I gave them space. There certainly was a large age difference between them, not to mention the size difference that we both shared, but together we’d made it work for almost a decade now. And on this fourth pregnancy in that time, I was ready with a plan to give Kenji the greatest gift I could.

I took a deep breath and called out "Kenji," loudly before letting it out slowly. My insides churned as they squirmed about, getting antsy to see the world. With experience had come wisdom and I knew today would be the day I would once more give birth to a veritable litter of my husband’s children. Having my belly engorged out to ridiculous proportions I’d been assigned bed rest by Yuki for the last month, but soon that would be all over.

"Yes, my love?" he poked his head down into my bedroom from the window as he arrived.

"It’s time to fetch Yuki," I answered and began my huffing breaths to relax my body as my first painful contraction began.

"It’s now? Oh, shit! I’ll be right back with her!" my adorably nervous spouse panicked and then I felt the ground shake as he took off at a run to fetch our midwife. All the kids and Natsumi came in to check on me, all excited, but once everyone saw I was fine she rounded them up and out into their playroom while she offered to go fetch my mother.

"Oh, dear gods, no!" I gasped, worried she might actually bring her again. The first time I’d insisted and she was a nutcase getting in everyone's way with stupid orders as if she had become the queen of my household. The next two times I invited her, but warned her to keep her place and let Yuki do her work, but still, she managed to make life horrible for everyone around her. In fact, I’d she should have remembered that I’d planned to only let her come over after they were born, and even then only begrudgingly because she was their grandmother. Then I caught the glint of her dry humor in her eye and threw a pillow at her as best I could in my incapacitated state, woefully poorly and just landing on the floor away from her feet. "Not funny!" I grunted and went back to the breathing exercises she had taught me.

"Sorry," my threesome partner smiled like a wolf, "I couldn’t resist." Then she was silent for a long moment before she returned to serious and asked, "Are you still planning to go through with it? Your plan?"

I gulped, knowing it was dangerous given the nature of how much damage could happen to my body during childbirth, but I’d been envious for a long time of how only Natsumi had been able to eventually accept all of our lover’s love. Sure I’d had over a half dozen children in just three pregnancies with him, but in all those cases I’d been inseminated indirectly, or with just his tip poking at my slit. Even with years now of trying to stretch open my various orifices I still had never truly felt my husband inside of me where he belonged. I was much smaller of frame than Natsumi, but looking at their faces when she took him inside, even if she could only accept half of his rod, I was jealous. Thus leading to my plan for today.

"Yes," I said defiantly. "I know the risks, but I need this, Nat."

Natsumi nodded silently, and I think she understood. "Alright, I’ll take care of the newborns, but you have to promise me that if it hurts too much you will stop. It’s not anyone’s fault he’s so big. Not his and certainly not yours. He still loves you no matter what."

"I know," I sighed before tensing up as the next contraction came painfully, faster than I expected. "Oh, boys stop fighting…" I groaned at my whale of a belly. "At least three this time from how they are shoving each other to get out."

"Well, here comes Kenji with Yuki," Natsumi answered and I was actually surprised I hadn’t noticed this time, but I guess the pain was pretty distracting.

Yuki was a doll as always, helping ease the pain with her herbal potions and over the next few hours easing out a total of three baby boys and even another two little girls. This was by far my largest litter yet and gave me confidence that I could handle the next task I’d set for myself. Natsumi, having only finished nursing her last clutch of three was still able to quickly wet nurse my new brood and introduce them to the mob of our other children who were amazed by these new little people I'd just produced.

Once the afterbirths were taken care of she pulled out her needle and thread. "You sure you want me to wait?" she asked with loving concern for my welfare much as Natsumi had. "If I don’t do it quickly you could get an infection."

"Please," I begged, still breathless from the hours of pushing. "I just need a few minutes with Kenji first."

"Alright…" Yuki said, clearly indicating she thought this was a mistake. "I’ll send him in."

"Thank you," I said honestly to my childhood best friend. Only half a moment passed before Kenji came in, cautiously.

"Are you alright, love?" he worriedly asked.

"What a mess I must look like," I sighed and tried to brush my hair with my hands. Suddenly, despite everything I felt like I was ugly at this moment, covered sweat and rank with the stink of blood.

"You're beautiful," he insisted and came up to gently pet my head with one massive finger three times the size of a normal man’s.

"Then make love to me," I said and spread open my legs. I had Yuki remove the piles of bloody towels I’d laid on, yet still, the bedsheets were brown from it and my bleeding gaping hole couldn’t have looked appealing. "Please, I’ve only got a little time before Yuki has to sew me back up," I begged. "Let me feel you inside me, just once."

"But…" Kenji looked white as a ghost at my request, but I knew I couldn’t let him deny me this one request.

"I’ve born a dozen of your children, and probably will a dozen more if I live long enough," I insisted and we both knew by now that was likely true. Yuki was honestly impressed that we’d fared as well as we had over such extreme pregnancies, and somehow still not had any serious complications. After our first pregnancies, we thought it was luck, but by now it was past amazing; we seemed destined to carry as many of his children as our bodies could handle, and then some. She figured it must be magic since even in the best of times one in ten normal births ended with a dead mother, and even more often a stillborn babe. Whatever magic that had grown Shinji that Kenji forced into him had somehow blessed the mothers of his children with both with the ability to survive normally fatal multi-child pregnancies, and the long and painful birthing process, as well as leave his offspring durable enough to survive in such an overcrowded womb.

And at this point, I was honestly betting on that magic to allow me to get through this next bit. "Please," I begged again. "I need to feel like your woman. Just this once." He adorably bit his lip and I could tell he was torn between wanting to and not wanting to hurt me. "I’m all numbed up from Yuki’s drugs, so I won’t be in any pain." That wasn’t really true, as only my outside skin was numbed from her salves, but that last bit seemed finally good enough for him and he started taking off his pants. "Hurry," I urged him on. "I can already feel my cervix closing."

He wasn’t hard, so he had to suck at my gushing tits that had grown so large from my hyper pregnancies that they rested on my belly while I was pregnant, and hung down to my navel when I wasn’t, but at least that meant they were large enough that he normally only sucked one whole breast in his mouth at a time. Now vacant my wrinkled belly flesh had already collapsed down from its overstretched limit out past where my arms could reach and now was down to what a normal pregnant woman might look like at seven or eight months. Feeding a gaggle of fetuses was hungry business, so of course, I’d put on a bit of weight, but luckily Kenji really got turned on the more pregnant we got. Oftentimes near the end of our terms if we weren’t able to please him he simply jerked off looking at us all bloated and round with his offspring.

Honestly, if it hadn’t been for that I think I might have resisted getting pregnant again after the first time given how exhausting an ordeal it was, but after those first two wonderful girls, my body seemed empty and void without a new life growing inside me. By the time a year had passed, I found myself unable to resist masturbating in a bath of his baby batter after he’d cum all over me. Those were some of the strongest orgasms I ever had, knowing that pushing his potent goo inside me might once more take hold inside me and fill me to the bursting point over the next several months.

To help him along I wrapped my bare feet along each side of his shaft and tried to stroke him hard, and with a little work and teasing, he was ready enough. But still, once more he offered, "Are you sure about this? I won’t love you any less if you…"

"Stop talking and fuck me," I growled, trying to spur his determination. He chuckled and moved forward, taking his place. With his unique size and our rapidly multiplying family size, we’d had to build this house to accommodate both needs. He usually slept out on a gigantic carpet in the common room where the was plenty of room to stretch out, Nat and I had our own bedrooms, but they were made with very tall ceilings and long enough beds to accommodate him and us all. He placed one foot on the floor of each side of the king-sized bed, straddling it as my feet rested upon his tree trunks for thighs. Then he grabbed the rafter above for a handhold, and with the other directed his third 'leg' towards my gash.

I heard his head wetly toying with my gaping outer lips, and his motions moved me and the bed, but they were still pleasantly numb as I had expected. I felt myself stretch back open and he looked up worried at me, but I just nodded and he continued. I wished I could see past my crotch, something I’d not done in years now, but I could see from his face that same intense battle of ecstasy and worry he always had with Nat when she took what she could of him inside. But I still couldn’t feel anything other than sore pressure down below so spurred him on with, "Deeper!"

"You sure?" he asked again and I uselessly tried to push myself down, as if I had the strength to wiggle more of him inside. I could tell from his hips that there was further he could go, yet he held back.

"I was just full of your kids an hour ago, and they weren’t so gentle. Now get your fat dick inside me and fuck me right," I demanded, getting a little testy. With a grimace, he placed one hand around my back and hips and used it to hold me while he pushed a little deeper, and then I felt my insides pop back open. "Yes! There! That’s it!" I groaned as my poor cervix once more stretched wide and this time accepted his massive member directly inside my womb that had just emptied, yet even then I knew I could take more. "Deeper!" I begged, "Give it all to me!"

I watched then as my stomach distended once more like a child’s head poked up in my stomach and I knew it was the knobby end of his three-foot cock deep in my swollen uterus. I used moth hands then to wrap around my giggly soft belly flesh and squeeze around it, and that really got him going. He started pulling back and thrusting as gently as he could, only going back out to where my birth canal stated before driving back up inside me to where my hands tightened around him. It wasn’t exactly pleasant for me, but watching his eyes roll back in his head was totally worth it. My love for him and the joy I felt at taking all of him as no one had ever done was euphoric in its own right, so when he began panting and I felt his balls that had been spanking my ass tighten after only a minute of this I knew he was about to cum.

"That’s it, love. Fill me back up with your babies!" I groaned and cheered him on. "Pump me full... Put a dozen more... deep in my womb!" That was enough and I swear I could see my belly ripple up with his hot potent jets of semen as he put his gallon of fresh sperm directly inside me for the first time. That did set me off on a weird and deep sort of internal climax that I’d never experienced before and likely wouldn’t ever again. So I cherished the painful sting on all my open cuts and tears as his salty injection washed over them.

He was panting heavily and looked down at me, maybe thinking me in pain, and started to pull back once his throbbing had diminished, but I pulled on his fingers beside me. "Wait, just… stay inside me as long as you can," I begged again. "I just…" and then I started to cry. My emotions were all a wreck now from the pregnancy and now the sex. But he lovingly pet my hair and told me I was wonderful as he stayed inside, plugging my womb for another ten minutes before he softened enough for my constricting womb to spit him out.

I didn’t think I could get pregnant so quickly after having just given birth, but I sloshed with his seed inside me for a week or two before I felt the slight pinch in my side indicating an ovary had dropped another batch of eggs into his potent soup still coating my womb. I knew in only days that it had taken hold and somehow without telling her Natsumi knew as well. She was only four months along on her third pregnancy and sometimes claimed her ovaries were drying up since she was getting old, now past forty, but even then she’d had five children in the last two pregnancies.

Late one night long after the older ones and Kenji had already gone to bed, while we both nursed my new litter, she whispered to me, "Seems like we’re never _not _going to be pregnant until we die." I smiled and then she confessed, "I think I’m gonna try that trick that next time too." All I could think was it was a good thing she was about halfway along and the nine-year-olds were getting old enough to really help out caring for the younger ones because I had the exact same thought. At least that would keep us staggered so only one of us was birthing at a time now.
