The twins are getting ready...

"Is it time, Fumi?" I asked after putting down our toddler baby brother in his bed next to his own twin brother, then heard a pack of our slightly older siblings go running by excitedly.

"I think so, Hana," my twin sister Fumi answered snidely before she started walking after them. "Daddy took her to bed in the middle of lunch," she said over her shoulder.

"That's good," I said to no one in particular. I had been worried that Mother's current labor was overdue, and since Great Granmama passed away last year, this would be my first time delivering our newest siblings without help. Well, Fumi would be there, but she'd only stand by and watch as always. She thought it was interesting, but gross so wouldn't actually help more than to hand me things. The next oldest were boys so they would just be a distraction. Little Iku and Riku were only six, but they were the next set of girls that were likely to be the most help and would listen to me.

Gathering up some towels and the washtub, I made my way to our parents' bedroom. The mob was all standing there giggling, and I knew why. "Alright, everyone back to the kitchen and finish your dinner. Iku could you boil me some water. Riku go fetch me some cold water from the fountain." The crowd of our siblings knew enough by now to listen to me. Either that or Fumi would get mad and enforce my will in a reign of terror. As such I almost never had to raise my voice or ask twice. It was nice having an enforcer, but sometimes I worried that Fumi liked being a bully a bit too much. The fights between us were always strange to behold, me never raising my voice soft as Fumi at me, identical in every way but attitude.

While all our siblings had been at least twins, only me and Fumi were truly identical. We were even supposed to have had a brother, but Fumi always teased that she wouldn’t share a womb with anyone other than me since he had been a stillborn runt. Not that we had any shortage of brothers; just they were all younger than us. Wondering what Mom would pop out this time I entered the half-open door and quietly walked in with Fumi soundlessly at my heels as always.

"Fuck, yes!" Mom groaned as Daddy pounded her from behind. "Lube me up, good honey. It's not gonna be long now."

"You got it, babe," Daddy groaned and I could smell the distinct saltiness of his sperm flooding into Mom’s opening vagina.

"Oh, yeah! You’re making me cum again," she whimpered as she shook and buried her head into her pillow to muffle a long, loud orgasmic scream.

The door opened and Riku came in with the cold water and I wordlessly pointed at the tub and she filled it before leaving. With such a big family we had all seen Mom and Daddy make love countless times, and I had seen what Great Granmama called their unusual birthing procedures, but even she agreed that no other babies she’d delivered were as quick and without complications. So far only the only child they had lost was the brother me and Fumi should have had, so she had never complained about it that I remember. Just in time, Iku came in with a big pitcher of steaming hot water and I started mixing it into the tub of cold water to get it just the right temperature as I’d been taught, and then, almost as if on cue Daddy backed away and collapsed into his chair saying, "It’s time girls."

I stepped up behind Mom and examined her wide open birthing canal, sticky and white with my father's sperm and mother's cum, and just watched as it stretched wide to allow the head of my newest sibling to start being pushed out. With Mom still muffling her cries into the pillow as she was propped up on her elbows and knees I laid out one towel between her legs and held another and just let her contractions gently ease what was probably her first baby of this pregnancy out and held its head until the slimy tiny person popped free.

"It's a boy," I announced to the room, to general happy cheers. He didn't scream, but gave a few gasping shouts as I cut his cord and tied it off before gently dunking it in the tub to clean off the sticky residue of blood and cum. Only then did Fumi take him from me so that I could go back to Mom with the next towel to see who else came out. Most unusually only the placenta came out about five minutes later, and I was unsure what to say. Mom just stayed there on her knees for some time, so I gritted my teeth and did the only thing I could, placed my hand in her still open vagina, and carefully pushed my hand inside to feel for any other baby that might just be slow in coming.

My whole small hand easily slid inside and I went almost elbow deep and could feel my wrist enter through her sore stretched cervix, but her womb was empty. "I guess that's it," I said just as surprised as everyone else as I withdrew my sticky hand and washed it off.

"Really?" Fumi said shocked. "Maybe I should go in and check to make sure you didn't miss one." She was teasing and I scowled at her, making her change tact. "So… what should we call him, Daddy?"

"Kenji Matsomoto Junior," he smiled proudly at took the child from my arms and kissed him.
