I'm not doing anything wrong...

Setsuko kissed Yuki tenderly as they undressed and she eagerly responded back. Very quickly she moved her head down to her breasts that were still smaller, though had grown quite a bit since our younger days thanks to the growth she experienced from each of her pregnancies. Setsuko hadn’t changed much during hers, but maybe that was because hers had been so much larger, to begin with. Yuki however really loved how much growth she’d had there, so really loved the attention. She would often say with the next one she would surpass Setsuko’s bra size, so it had become a friendly competition, and I enjoyed judging it often.

Once they were the rest of the way naked they started using their mouths in other places and I was just stoking up to a good hard-on as I watched when little Gendo came in the room. "What are you doing daddy?" he asked innocently as any six-year-old would seeing his dad jerking off.

I held up my finger to my lips to signal for him to be quiet as I eased back from the peephole in the back of the bathhouse. My son was supposed to be out playing with his cousins today, but it seems Kouki must have grown tired of babysitting my gaggle of rug rats. That meant playtime was over for me, but hopefully, I could let the ladies continue their ‘no boys allowed' party in peace. If Setsuko didn’t get her fill of alone time with Yuki she could get mighty cranky. Besides on days, they got like this there was usually a good night for me later on since they would both then focus on me the whole time.

"Just… uh… checking for leaks," I said making something up. "Don’t want all the water escaping the bathtub do we?" I said picking up my son and walking back to the house with him. "Where’s Auntie Kouki?" I asked.

"Right here," Kouki, now five months along on her second child herself said coming around a corner carrying my youngest daughter who was only two. "Sorry, but Natsumi needed Shinji to…" she started, but stopped as she looked at me. "Ahem…" she pointed down and I looked and saw my boner was poking obviously in my pants.

"Sorry," I said shifting it down my pant leg quickly before grabbing Osanna from her.

"So everyone else is down and napping," she informed me.

"Alright," I answered. "Thanks for watching them even for a little bit."

"No problem. I…" she chatted happily when she was interrupted by a piercing orgasmic squeal from Yuki clearly enjoying whatever Setsuko was now doing to her within the bathhouse behind me. Kouki paused for a moment and then just continued as she walked back to the Takahashi manor house, my home again, though without the name since Setsuko refused to marry me, despite having already had two of my children. She said she didn’t love me, just my cock, but I was okay with that. I had proposed to Yuki, but she said she loved me and Setsuko equally, so wouldn’t do anything that would upset our strange balancing act of a threesome.

Little Genma however had gotten a funny viewpoint from my earlier explanation so tugged on my arm and pointed back to the bathhouse. "Mommy found the leak!"

"She sure did," I smiled and brought him back into the house.
