Every day Keku threw a fit about having to leave soon, and every day he immediately squealed with glee the moment mommy actually walked through the door to pick him up. It was cute, though slightly less so after the thousandth time. All the same, I smiled and scratched his head as I came up to Mei.

"Did they behave all right?"

"Keku had to sit in the corner a while for not sharing the blocks," I began, loving the steely gaze that formed above her warm smile. Even loving the fear in our son's eyes just a little. "But he already apologized and got punished for it, so I think it's fine," I added, immediately bringing some hope to the boy's eyes as I mussed his mop of golden blonde hair.

She only hm'ed in response, putting the fear back on him.

"Well, thank you for watching them,"

"Ha! It's a lot more fun than what I do in my office, most of the time," I teased, bringing just a ghost of a blush to the older woman's stern face. We'd spent our lunch break together, as we did most days, and we'd had a little fun as we often did. There was something so wonderfully exciting about talking like this, like casual acquaintances, after I'd mounted her over my desk not five hours ago.

She almost seemed to flee as she gathered up our two present kids and rushed off.

Despite how much I loved the job, I groaned in relief, falling onto the miniature table where the kids ate their snacks and made their little crafts.

"I can handle the rest of the cleanup if you want to go," the only other adult, and in fact the only other person in the room, piped up. I gave her a warm smile, retaking my feet.

"That's alright, I'll help,"

"You have a family to go home to," she argued, for the thousandth time.

"Believe it or not I could use a break from kids right now," I joked, earning the most beautiful soft sound. Shiseru had such a wonderful laugh. I got to hear it all too often working in the nursery with her. The poor woman loved kids but never got to have any of her own. Some medical reason she'd confided in me. This job was perfect for her.

Plus, I got some eye candy throughout the day. She was a wonderfully curvy woman, chest just a cup below Hinata, narrow hips with a plump ass, dark eyes that stood out against light skin. Even wearing her simple work pants and black top, even with her hair up in a messy ponytail, she was absolutely gorgeous. We didn't work together a year before we ended up at a love hotel. One of the more… spirited children had finally been broken. Made it through a whole day without a major incident or a temper tantrum.

We hugged each other in celebration after the nursery was empty. We held each other a little too long. I invited her to join me for a drink that weekend to celebrate. We both knew what would happen, what I really proposed. We'd known each other long enough. She thought about it a half a minute before giving a simple okay, blushing and smiling and ashamed. I'd told Hanabi that Mei needed a weekend visit, and she told Hinata she needed me Saturday afternoon for work.

God the sight of Shiseru when I walked into the hotel bar. That shining auburn hair down, cascading down her back for perhaps the first time I'd ever witnessed. Definitely the first time I'd ever seen her in a dress. A long ebony black one that looked like it had been painted on her body. I hadn't actually intended to drink any, but I ordered one to calm my nerves.

It wasn't like me to actively pursue a woman like that, to try to instigate yet another affair, believe it or not. Shiseru was special. I mean, sure we only saw them during the workday, but we were practically raising a class of children together! That was a unique bond surely.

"Naruto!" she cried out in shock, as I wrapped an arm around her from behind.

I placed a kiss on her neck.

"I was just thinking about the hotel…" I admitted, delighting in the red blush spreading over her frazzled face. She felt so soft against me, particularly that ass, where my erect cock found its cushion. She made no effort to break my grip or pull away. Even resting her head on my shoulder.

"Y-Yeah?"

"Yeah," I added, kissing a couple more times. She bent her neck to give me more access, humming contently as my hands weaseled their way from her hips to under her form-fitting shirt. Such wonderful, soft skin. "You know how much it works me up, watching you look after the kids? That sexy, nurturing, motherly way you dote on them? I don't thank you enough for taking such good care of my children,"

I took her lips this time. She eagerly responded, opening her mouth quickly as I poked at it with my tongue. She remained there, locked against my back as we made out in the empty classroom. We usually had sex in my ground floor office, but it wasn't the first time we, I, had gotten too horny to wait and jumped on her in here.

It didn't seem to bother her any.

My hands shifted direction, one dipping down into her panties and then into her snatch, the other coming up to cup that magnificent breast. She groaned heartily into our kiss. Only breaking it minutes later when a gasp helped some words slip out.

"Oh God!" I grinned wickedly when she chose to take some deep breaths instead of reattacking my lips, then decided to bring them over to her ear.

"I just think about that sexy black dress, these gorgeous breasts practically popping out of it…" a wet kiss on her cheek brought another gasp. "And somehow you drive me even wilder in your work clothes," I added whimsically, moving my hands to her pants and ignoring her half-coherent noise of protest. Pulling them down with well-practiced ease brought my cock one layer of clothing closer to her center.

"Put it in," she requested breathlessly, tugging my smile up a little harder.

Meanwhile, her face contorted as if in pain as I slowly shifted inside of her. Both hands came up to grip that wall, balancing there while she bent over for me. She really was an incredible woman. Even as I betrayed my wife and more than a couple other lovers, I couldn't help but feel happy, proud almost. Pulling out nearly all the way to stab her with another hard thrust only furthered the feeling. The way she gasped in gurgled in pleasure.

She deserved it.

I never knew just how much Shiseru disagreed. She didn't even try to justify this to herself. Cheating on her husband, helping him cheat on his wife, stealing time from work? It was borderline evil, especially when she thought of his half-dozen children who might be affected if she ruined his marriage. Not to mention the class losing their teacher. She felt so wicked, so selfish, so unbelievably aroused.

Even so, her partner looked at her like an angel, like a mentor at first even. Back when he was just a dumb new parent in his early twenties and she had a decade on him. He had just seemed so amazed by her, so resolute and vocal in his opinion that she was a parent in all but technicality.

I grew faster in my thrusts, still yanking out almost completely each time, loving the way it made her gasp and hiccup. She was so warm and wet around me, and there was something so unbearably erotic about doing it here. About working innocently beside her half the day and then bending her over like a whore as soon as the kids were gone. Stealing a quicky while we both had a minute free.

One hand flew off the wall, muffling her noises as she bit down on it. The way her body convulsed and spasmed as I rode out her orgasm was exquisite, it wasn't until she started going limp that I hunched over her like an animal, sped up, and exploded inside of her.

She gave another groan, then a sigh as I pulled out.

"Oh wow Naruto that was…." she wiped some of the sweat-soaked strands of hair away from her eyes. Then she cried out in shock as I fell to the floor and brought her down with me, carefully cushioning her fall of course. "Again?"

I only kissed her neck and dipped my hand back into her wonderfully gooey womanhood in reply.
