Akira switches to her vagina

Emi felt as her son pulled away from her. She felt a confused moment of disappointment as her orgasm slipped away, but then she heard his thoughts. Now that he owned her body, he wanted more of her. He wanted to coat her insides with his cum and fill her womb with his seed. She knew it as certainly as she knew that he would not stop until she was bulging with his child.

Reaching under her body, she spread herself open for her son. She smiled to herself as she felt him approach and use the slick fluids leaking out of her to lubricate himself. She moaned at the pleasure of his cock as it stroked across her slit. 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 a sense of euphoria, like an itch that hadn't been scratched in years, that rushed through her body as he entered her. She felt him dive into her silky folds with years of desire driving him forward, and she let out a moan of pleasure as his cock filled her completely. She wasn't sure if he was fully inside her, but she filled him completely regardless, and it meant that he was the perfect cock for her, from his length to his girth.

She flinched as he took her so aggressively, but as his cock slid into the silky folds of her interior, she placed both her hands on her desk to prepare her for how aggressive she knew he would be. She felt him place both of his hands on her hips and pull him into her, forcing his cock even farther into her, stretching her insides as the tip of his cock struck the end of her vaginal canal. She let out a scream of pleasure, knowing that it would be undeniable now that she was his woman.

"Akira," she screamed.

"Mother," he moaned in response.

He began to move, slowly at first, causing his cock to slip in and out of her tight folds. She tightened her interior muscles again, clamping on his cock and feeling it touching all of her interior spots simultaneously. He'd already filled her, something impressive for a woman who'd given birth to two sons naturally, but as she clamped down, she felt him shiver with excitement. She wanted his cum inside her and he knew it.

She rocked back against him while he drove himself deeply into her. They both began to moan with the deepest pleasure as they both drove themselves to find the other's 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.

"Aki-" she began.

"Moth-" he said at the same time.

She felt the walls of her vagina crush tightly against him as the orgasm rolled through her whole body. The muscles in her legs gave out and she felt the desk dig painfully into her thighs, but Akira did not stop. He leaned forward and as her orgasm continued, she felt his cock ramming hard against her cervix. Her son was not going to stop until he completely filled 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.
