I couldn't see as much as I would have liked. It was too blurred for that. But I got the gist of what my sisters were up to. In particular, by the time I left, Elsa was indeed on her knees helping Anna out with her creampie. Knowing Anna, she was only willing to let Elsa clean that up because she had cum up her booty as well.
I was hard again, visions of Elsa and Anna in my head. Grinding slickly together, all naked and wet in the shower. Kissing and fondling and rubbing up on each other. And imagining Elsa's talented tongue doing naughty things to Anna's messy little pussy.
I got dressed, but was unable to do anything about my erection. I worked on breakfast while the girls were still showering, and managed to get some muffins out of the oven by the time Anna came through in a whirl, still adjusting her hair as she walked.
"I'm late," Anna announced, as though it was going to be shocking news.
"I know," I said. "Take a muffin with you."
"Mmm, thanks. I really should eat something... other than Elsa."
I smiled and gave her a quick kiss, handing her an only slightly cooled muffin, then she was gone again.
Elsa was slightly more dignified coming through, but only just slightly. She had no bottoms on, and was in fact carrying half her clothes in her hand. I'd been missing the days of casual partial or full nudity around the house, and took a moment just to appreciate my big sister with her pussy peeking out at me.
She smiled and casually posed for me, letting me soak her in.
"Awfully risky," I said.
Elsa shrugged. "Casey's got the kids for a bit."
"Oh?"
"Yeah. I've been missing fucking around in whatever room we like."
I nodded. "Me too."
"So... wanna fuck in the kitchen before I gotta go to work?"
"Do you really need to ask?"
Elsa smirked, carefully piled the clothes she held in her hand on a chair, then stepped up to me for a long, body-melding kiss.
"That's what I was hoping to hear," she murmured.
I made out with Elsa some, reaching down to play with her butt since it was so nicely bared for me already.
"Is your ass lubed already?" I asked, discovering how slippery her tight little hole was with my finger.
"Maybe."
"Naughty."
Elsa tossed her hair flippantly. "Just being efficient. I don't have long before I need to get moving."
"But you want it in the butt, huh?"
"It's better for keeping cum in all day. Don't want to be totally sloppy and messy at work, you know."
"Ah. Pragmatic, is all."
"That's right."
Elsa turned from me and bent over the counter, presenting her bumhole for my approval. I slid in easily. Elsa was good at anal anyway, but I had strong suspicions Casey had helped her warm up this morning before she got to me.
"Daaammmn," I moaned.
"Mmm, you love it every time, don't you?" Elsa purred.
"Just as much as you do," I said.
I thrust in Elsa's ass, giving it to her nice and smooth. Once we got going, I reached around to rub her clit the way she loved, the way that would make her feel really good. I wanted her to cum for me with my cock up her ass.
"And Anna," Elsa said. "She loves this stuff so much."
"Almost like you're sisters."
"Mmm. Almost like that." Elsa smiled fondly thinking of Anna, then gave me a sultry look over her shoulder. "Cum in my ass for me, ok?"
I whimpered softly as her request had its intended effect on me. "Working on it."
It took a little while longer to give Elsa what she asked of me. Then, with her cummy bum and my cock still buried inside, she got to cum too.
We shared some happy kisses, then I watched her finish dressing, knowing that my cum would stay snugly in her ass all day. Same as with Anna. My horny, loving sisters.Alright, I need to be off," Elsa said. "Love you. See you later."
"Love you," I called, still watching wistfully as Elsa left.
I lingered a moment, then set off to find Casey. She greeted me, kissed me good morning, and happily fobbed all the kids off on to me while she grabbed a shower.
Between the four of us, we tried to make sure at least two of us were home on any given day. Wrangling three small kids took a lot of energy, mental and otherwise.
Today it was Casey and me. We were kept fairly busy, right up until we somehow managed to get all the kids down for a nap at the same time. It felt like quite a feat by the time we sneaked out and slunk wearily onto the couch together.
"So much work," Casey complained.
"Tell me about it," I said.
"I wanted some time with you, and now that we have it...."
I smiled wearily. "Right?"
We just sat together for a while, until I managed to work up some energy. Casey giggled as I knelt down in front of her and got her bottoms out of the way. I lazily ate her out while she gave me equally lazy head pats.
I thought make her cum with my mouth would be about the extent of it. But Casey found some horny energy afterward and climbed into my lap to slowly ride me.
"Just want to get another one in before the kids wake up," she murmured.
"Mmm. Noisy little things, aren't they?"
"Well you know whose fault that is. Only one of us had a hand in all three."
I pouted. "I don't think you can blame me for that."
"Watch me."
Casey kept riding me, and eventually I came in her pussy. She stayed snuggled up on me, the two of us enjoying the moment, until the inevitable crying began. Always with the crying.
I sighed. "Best get our clothes back on."
"Ugh, I know."
I gave Casey a final kiss before we got up and sorted ourselves out. So little time for cuddles these days. Such a shame.

We collectively got better at managing time and the kids as we developed habits and schedules. The kids growing up a little helped too, though their extra mobility was a sheer nuisance for a while. Still, it was something.
If anything, I only fell deeper in love with Anna over time. Like we were always meant to be together. We played around with Elsa and Casey plenty still. No changes there. But they were married, and Anna and I might as well have been. I toyed with the idea sometimes of doing it officially. Anna got in on the daydreaming, but we both knew it was just wasn't for us. Being brother and sister and all.
None of us particularly knew what we'd tell the kids when they were older. We couldn't hand wave everything away. It wasn't a typical household by any stretch of the imagination.
It wasn't an immediate problem. The family was happy. I got to really enjoy the simple things like sitting out back and watching the kids play, particularly with someone next to me. Anna, more often than not.
"This part's good," Anna told me.
I nodded easily in the fading evening sun. I took Anna's hand and interlaced our fingers. "It is."
"No one ever explained how hard raising kids is. Why is that?"
"I don't know," I answered honestly. "But everything seems good when you're around."
"Yeah. Yeah, same." Anna sighed and leaned against me. "I just want to take these lovely, peaceful moments and--"
She was interrupted by a loud scream from the yard. We both groaned simultaneously.
"Blurgh. Who is it?" Anna asked.
"Can't tell."
"Guess I should go see."
"Nah, you stay. I got it."
It was an effort tearing myself away from Anna. But she'd still be there when I dealt with whatever minor tragedy had no doubt just occurred amongst the kids. I looked back over my shoulder at her as I left, and the soft, beaming smile she still held for me made everything just seem so damn good.
