In her ass

Breaking the kiss, she turned around to face her desk. Lifting her skirt, she pulled her panties down to her over her hips and let them fall to her ankles. Looking back over her shoulder, she decided that it was time for him to dominate her. He would not be satiated simply being her lover, she knew, he had to know that he truly and deeply owned her body, and she was already slick thinking about her son becoming her master.

His eyes fell to her ass as she leaned over the desk, and she knew that he was second guessing what was about to happen, but she also knew these thoughts were conflicting with the ones in his mind that wanted him to do it. He tried to look away, but as he did, Emi watched as her son's eyes fell to the open book on her desk. As his eyes fell to the inscription, Emi watched as his face changed, and in that moment, she knew that he knew that she knew he wanted her. All thoughts of resistance disappeared.

Laying her chest flat onto the desk, she slid both hands down her hips and grabbed each of her cheeks to spread her ass open for her son. The motion caused his eyes to drop to her opening, and when it did, she saw his cock engorge even more than before. She knew that he was ready to break every societal rule that kept them from being together. Turning her head to look away, she smiled to herself as she heard him spit into his hand, preparing himself to slip into her.

She moaned at the pleasure of his cock as it stroked across the sensitive edges of her opening. She briefly felt the head of him touch her fingers and it caused an electric excitement to course through her body. It was replaced a moment later by an intense stretching feeling that initially caused her a strange feeling of pain, but it was a different kind of pain than she’d felt before. Something about this pain was intensely erotic, something that she’d never felt before in her life. Her son was truly doing something that she’d never done with any man ever before, and therefore he would own that part of her forever.

Emi felt as nerves she’d never felt before awakened inside of her as Akira pushed himself deeper than any man she’d ever felt before. If she’d been uncomfortable before, these nerves changed that moment, and as she felt her body tightly squeezing on his cock, she wanted nothing more than for him to continue awakening things inside her she’d never felt before. She wanted him to push her levels of desire that she didn’t know she had, and her son obliged as he continued to push himself inside her.

"Akira," she moaned, dropping her head to her desk.

"Mother," he moaned in response.

He began to move, slowly at first, causing his cock to slip in and out of her tight asshole. Remembering something she'd read a long time ago, she clenched her interior muscles, clamping down on him as tightly as she could. As she clamped down, she knew he was surprised and impressed with her. She was going to milk all the cum from his cock, and in that moment, their minds linked on this fact. And in that linked moment, she knew that he was planning on forcing his cum as deeply into her ass as he could.

As they both shared the mental realization that she was going to have his seed inside her, they both began to move. She rocked back against him while he drove himself deeply into her. She felt her ass ripple as she slammed into her, and she enjoyed the feeling of him taking her entirely. Her body was entirely his, and she knew that he knew it. She grinned wickedly, knowing that this was going to be a moment they shared together, the moment that he took her special hole. She felt the urge to really drive him into her ask, forcing him to destroy her ass for all other men. That would truly prove his dominance.

Instead, she kept going, moaning with the deepest pleasure as he continued to find her pleasure spots. Her heart began racing and her blood pumped. She felt a tingling that ran up her spine and deep into her stomach, a feeling that she'd never felt before in her life. This moment was the most intense sexual feeling she'd ever had, and she knew, deep in her mind, that it was the same for him.

“Mother," he said, "I’m going to go faster now."

"Yes, Akira," she moaned in response. "Take me."

He began to thrust faster, making sure to distinguish between faster and harder. She relished in his expertise, surprised by her son's abilities considering that she knew how little he'd been sexually active. He clearly knew that harder was different than faster, but she hoped that harder would come soon. She wanted to feel him truly releasing his desires into her before he filled her guts with his seed.

She began to squeeze and release her opening in response. He clearly enjoyed what she was doing because a moment later, she felt his hand come to the back of her head and grab a handful of her hair. She moaned excitedly as he pulled her head back and began pumping as fast as he could into her ask, using her body for his pleasure. Relaxing her muscles, she became as pliable as possible to him command and moaned deeply as he thrust his cock into her again and again.

As soon as her moan ended, she felt a sharp pain as he smacked her ass with his free hand.

"Akira," she said with amazement.

The hand that had just hit her ass came across her face. She knew that he'd read her thoughts about being harder, and she knew it was time. As soon as she knew, he began ramming into her as hard as he could. She felt him strike that deep pleasure spot inside her over and over again, causing sparks to course through her with each push. It was the most amazing feeling she'd ever felt and she knew that just as he would yearn for her again in the future, she would yearn for this feeling again.

Letting go of her mouth, she gasped for air the same moment she felt his arm snake around her waist. She felt his fingers touch her clit and felt the electric shock of having two different pleasure points on her body being stimulated at the same time. She let her head fall heavily on the desk and moaned into the wood.

"Aki-" she moaned.

"Moth-" he said at the same time.

She felt her ass tighten against him as the orgasm rolled through her whole body. It was deeper than any orgasm than she’d felt before, stemming from some point in her body that she was unaware even existed. Something about the way he was fucking her touched some part of her that had never been touched before, and her son continued as if was not going to stop until he was done with her, and that thought drove her more into the orgasm, feeling it roll up her spine, into her neck and across the top of her head. Her whole skin felt electric.
