Her youngest son

Emi's eyes fell upon her son Ichiro as he stood in the doorway. He was still wearing his uniform from the gym where he worked as a personal trainer, and she knew that he smelled of sweat, even from this distance. It was an intoxicating smell that she pretended not to love every time she met up with him after work and was saddened each evening after she showered it off. Sometimes, she'd wished he'd forgo his post-work shower before coming to bed in the tatami room they shared as a family, but she'd never said anything to him about it. As he stood there now, the scent permeated her nose and brought that familiar tingle she'd always denied letting herself enjoy.

"Mother?" Ichiro asked as he stepped into the room. "Are you okay? Akira and I waited for you at the corner for a while and when you didn't show, I decided to go looking for you while he went home."

Emi gave her son a smile and as she stared at him, she knew what was truly going through his mind. He’d been hoping to walk in on her blowing one of his friends in the stacks. She knew that his friends had always joked about having secret sex with her ever since they’d discovered that she’d been actively meeting men at love hotels around the time that her husband had died. It had been a tumultuous time, but that had been before she’d gotten the job at the library to give herself purpose. She could tell that his chest swirled with disappointment after not finding her with a secret lover in the back of the library.

She set the book down and waved him to come closer.

"I was waiting for you," she said as he approached.

"You were?" he asked as he moved closer.

"I was," she replied. "I know what you secretly want."

"You do?" he asked.

“I do,” she answered. “But better than your friends having me,” she continued with a sly smile, “wouldn’t it be better for you to take me?”

As soon as he was close enough, she reached out and gripped his shirt in her slender hand. Pulling him in, she planted a kiss on his lips. An indescribable feeling passed through her body, partly from that part of her brain that was actively controlling her thoughts and partly from the new desire rushing through her son and into her lips. She could feel what he was experiencing along with her own feelings, and that was more powerful than any human contact she'd had before.

At first, her son was confused, but as the realization that his mother was kissing him passionately, not the brief peck of a mother to son, she felt him giving into the ecstasy of the long forbidden moment. Emi felt her son relax in the embrace, and before long, she felt his tongue penetrating her mouth. She knew that he wanted to penetrate her with more than his tongue, and she did not feel the inhibitions that she should have felt as his mother.

Letting go of his shirt, she reached down to slide his gym shorts over his hips. Ichiro placed his hands on her breasts, groping them like he had wanted to do his entire life. She felt him moan into her mouth as she dropped his shorts to the floor, freeing his erection. She knew that all that kept them from doing what he desired the most was gone. His deepest desire was about to be filled.
