Chapter 18 : Surprising Discovery

Liz, her body still quivering from the force of their shared climax, noticed something unusual. Even after Seiji released his climax inside her pussy, his penis remained hard as a rock, defying the usual post-orgasmic lull. Her eyes widened with a mixture of surprise and curiosity as she reached out to touch him. "Why is it still so hard?" she asked, her voice laced with wonder. "I thought men usually went soft after climax."

In her experience with her husband, the penis would go limp after release, but Seiji's penis seemed to have a mind of its own, throbbing with desire as if it hadn't just experienced an intense release. Liz's curiosity piqued, and she felt a mix of excitement and anticipation.

Liz turned to face Seiji, her eyes sparkling with curiosity. "Why is it still so hard?" she asked, her voice laced with a mixture of wonder and desire. "I thought men usually went soft after climax."

Seiji, his penis still erect and throbbing, gave Liz a mischievous smile that mirrored the spark in her eyes. "Well, I guess I'm not like most men," he said, his voice laced with a mixture of pride and desire. "And I have a feeling this night is just getting started. We've only scratched the surface of the pleasure we can explore."

Liz, her heart pounding with anticipation, felt a rush of excitement. "Oh?" she said, her voice laced with curiosity.

Seiji pulled out his penis, still erect and proud, and gestured for Liz to turn around. "I want to try something different," he whispered, his voice husky with desire. "Something that will take us even deeper into pleasure."

Liz did as instructed, her heart pounding with anticipation. Seiji aimed his penis at her pussy from behind, a position she had never experienced before. Liz's breath quickened as she imagined the possibilities.Her body tingling with anticipation. "Like what?" she asked, her voice breathless. "I've never done it like this before. Will it be easier now that you've cummed?"

Liz felt the head of Seiji's penis teasing her entrance from behind, a position she had never experienced before. "Oh, Seiji," she whispered, her voice thick with desire. "You always know how to surprise me."

Liz, her body trembling with anticipation, felt a mix of excitement and nervousness. She wanted to surrender to the unknown, to explore the depths of their pleasure, but a part of her wondered if she could handle more. "Are you sure about this?" she asked, her voice laced with concern.

"We'll find out," Seiji replied, his voice husky with desire. He positioned himself behind her, his penis sliding easily into her sperm-coated passage. Liz felt the familiar stretch and burn of his size, but she was beyond the point of caring. She wanted to feel him in every way possible.

Seiji began to move his hips, his penis sliding in and out of Liz's tight channel with ease. Liz moaned with each thrust, her body responding to the sensation of his penis hitting all the right spots inside her. The new position allowed Seiji to penetrate her even deeper, his penis reaching places within her that sent sparks of pleasure erupting throughout her body.

Liz, her breath quickening, felt a combination of pain and pleasure that pushed her towards the edge. "Oh, Seiji," she whispered, her voice thick with desire. "It feels so good, but it's almost too much. I can't handle much more."

But Seiji, driven by his unrelenting desire, showed no signs of slowing down. His hips moved with relentless passion, his penis thrusting deeper into her with each stroke. Liz's body trembled as another orgasm built within her, threatening to consume her. "Don't stop, Seiji," she begged, her voice hoarse with need.

Liz, her body weak but her pleasure intensifying, felt a coil of tension building within her. Seiji's relentless thrusts, the position from behind, and his penis hitting all her sensitive spots, pushed her closer to the edge. Her breath quickened, her moans becoming more frequent as she approached the precipice of her release.

Her pussy clenched around Seiji's penis, milking him for more.She moaned, her voice thick with desire. "Don't stop, it feels too good." Her body trembled, her muscles tensing as the pleasure built to an unbearable level.

And then, with a powerful thrust, Seiji sent her spiraling into her orgasm. Liz cried out, her body shaking with the force of her release. "Ahhh, Seiji!" Her voice trailed off into a mix of moans and gasps as her body convulsed with pleasure.

Her pussy clenched and released, milking Seiji's penis with each contraction. Her breath quickened, her moans turning into incoherent cries as the pleasure overwhelmed her. Her body trembled, her muscles contracting and releasing with each wave of pleasure.

Liz, her body weak but her pleasure intensifying, felt a mix of sensations as her orgasms crashed over her. "Oh," she thought, her voice a mixture of pleasure and wonder. "I've never experienced anything like this. It's like my body is on fire, consumed by pleasure."

Liz, her eyes closed, her body convulsing with pleasure, nodded, unable to form words. She wanted him to continue, to push her beyond the boundaries of her pleasure, to explore realms of ecstasy she never knew existed.

Finally, after what felt like an eternity of ecstasy, Seiji reached his final load. This time, Liz didn't ask him to pull out. She wanted to feel him release inside her as she reached her own climax, their bodies moving in perfect harmony.

With a final, powerful thrust, Seiji released his warm seed into her, their bodies trembling with the force of their mutual release. They collapsed onto the bed, their hearts pounding and their breaths ragged. Liz turned to face Seiji, her eyes sparkling with a mixture of satisfaction and curiosity. "That was incredible," she whispered, her fingers tracing patterns on his chest. "I've never experienced anything like it."

Seiji smiled, his eyes dark with desire. "And we're not done yet. I have a feeling this night will be one you'll never forget."
