The rain had been falling for days and it did not seem like it would be stopping anytime soon. The dreary landscapes of Rakuyou were always an eyesore, but the rain seemed to make them even worse. Inside a rundown old building, Kouka was laying in bed and looking out the window. Next to her a small girl who looked no older than 5 years old was calmly sleeping. She turned her head to the doorway of the room as a young boy walked in and went over to her.

"Mommy, I'm cold" The boy looked up at her and shivered a little.

She gestured next to her on the bed and he eagerly climbed into bed with her. He snuggled up with her and sighed happily, loving his mother's warmth.

"Are you warm now, Kamui?"

He looked up at her then got on top of her and wrapped his arms around her body. His face pressed against her large chest and he looked up at her with a smile on his face. The woman smiled and let him lay on her, she also enjoyed the warmth from his body.

"Goodnight, mommy"

"Goodnight, Kamui"

Kouka yawned and closed her eyes. She had been getting tired quickly and needed to sleep. It was hard for her to raise Kamui and Kagura on her own. She knew Kano was busy and couldn't visit her, but that didn't make it any easier. She really missed having someone who would pay attention to her. She hugged Kamui and slowly drifted off while thinking of her husband.

Kouka was woken up abruptly by the sound of lightning streaking across the sky. She sighed and looked out the window. She frowned as she saw it was raining again She was preparing to go back to sleep when she felt something hard press against her and heard a gentle grunt come from Kamui.

She felt her face heat up and she gently shook him. He groaned and slowly opened his eyes. He had a bit of sweat on his forehead and his face was flushed. When he saw that she was looking at him he sat up. She could see a throbbing tent in his pajama pants. Kamui tilted his head then looked down at himself and whined.

"Mommy, it keeps getting bigger and I have to wait for it to go away"
He kept speaking and complaining, but Kouka wasn't paying attention to that, she was looking at his crotch. It had been forever since Kouka had seen one of those, but she was surprised that he was already big enough to make a large tent. Kouka blushed and looked down at him, her crotch was a bit wet just from seeing him like this.

"You don't have to wait, honey, mommy can show you a way to fix it"

She started removing his clothing and he blushed and backed up a little.

"Relax, mommy will take care of you"

She smiled and pulled his shirt off, then his pants. She looked over his body eagerly, her eyes were especially drawn to the outline of his member in his underwear. She wondered how big he would be, after all, he was still a growing boy, so she shouldn't expect much.

When she slid his boxers down her eyes widened in shock. A thick and veiny cock sprung up right in front of her. She stared at her son's dick. Holy shit, he is bigger then Kanko is! Her shocked expression quickly turned into a smug look and she sat in front of him.

"Mommy, this is embarrassing"

"Shhhh, relax"

Kouka gently grabbed his cock and moved her smooth hands up and down. Kamui trembled and he immediately started fucking her hands. Kouka held them in place and let him take control, he seemed to instinctively know what to do.

"Mommy, it feels good!"

She smiled and got on her stomach in front of him. She gripped harder and yanked on his member, making him cry out in pleasure. She felt so naughty doing this with her own son.

She smirked at the soft groans and cries he was making. His movements got faster over time and she could feel him building up quickly. She chuckled and started moving her hands again. He may be big, but there was no way he was lasting long.

"Mommy, I feel like it's going to explode!"
Kouka leaned down and placed a gentle kiss on his dick, making him cry out in pleasure. She kept rubbing and kissing his cock until Kamui moaned and shot his load all onto her face, making her gasp in shock. She wiped it off of her face with her finger and sucked it off with a smirk. She made the decision right there, she was going to let him fuck her.

She quickly stripped all of her clothing, letting her large breasts bounce free in the air and freeing her wet snatch. Kamui looked at her and blushed brightly, his long cock sprang back up into the air and a line of drool hung from his mouth. She laid down on her back and spread her legs to the sides. She hadn't been fucked in so long, and she was desperately craving it.

"Kamui, come lay on top of mommy"

Kamui listened to her and got on his stomach on top of her. He blushed as his face rested on her exposed chest and his dick pressed against her. Kouka smiled and held his head close to her chest. She gently guided his dick to the proper hole and rubbed his cockhead against it, making both of them quiver with excitement.

"Push it down into my pussy" Kouka whispered seductively to him.

Kamui slowly sunk his shaft down into her hot core. He moaned loudly and wrapped his arms around his mother, holding on tight as he went deeper into her body. Kouka moaned just as loudly as he did and she grasped the bedsheets in her hands. He felt much bigger then Kanko did!

"Y-Yes Kamui, fuck your mommy!"

He lifted his hips up and slammed down into her erratically. He was inexperienced, but he more than made up for that with his speed and passion. Kouka's tits jiggle about and seemed to catch Kamui's attention. He grabbed them and roughly kneaded them with his little hands.

Kouka's mind was a complete mess as she was fucked. He was destroying her pussy. She cried out in pleasure louder then he did and she wrapped her long legs around his back.

"More, Kamui, more!" She shouted.

Kamui stayed silent as he plunged deep into her core, making her spasm every time he hit her most pleasurable points. His huge cock reached all the way to her cervix and filled her with intense amounts of pleasure.

"Mommy, I-I'm going to explode again!"

"Do it, baby!"

He plowed her excessively until he couldn't hold it in anymore. His seed burst straight into her fiery core and he screamed in ecstasy. Kouka gasped as she felt the hot spunk enter her body in spurts. Once Kamui finished he collapsed on top of her and passed out, his young mind completely blown away.

"Oh fuck, that was a much better time then Kanko ever gave me"

Kouka relaxed, she was now satisfied and full of her beloved son's cum. They would definitely be doing that again. She smiled and fell asleep with his dick still buried deep inside.
