Her oldest son

Emi's eyes fell upon her son Akira as he stood in the doorway. He was still wearing his uniform from the coffee shop that he worked at as a barista and she knew that he smelled of coffee 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?" Akira asked as he stepped into the room. "Are you okay? Ichiro 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 worried that she'd gone to one of the love hotels with a secret lover. His chest swirled with jealousy, she knew, though she couldn't explain how she knew it, but it was clear as day to her. She set the book down on her desk and waved him over.

"Don't worry," she said as he approached. "I was waiting for you."

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

"I was," she replied. "I've always been waiting for you."

"Mother?" he asked.

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 and began to undo his belt. Akira placed his hands on her hips, holding her at a distance so their bodies didn't collide together and make it difficult for her to continue, but he never broke the kiss. She felt him moan into her mouth as she dropped his pants 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.
