More Cum

While Amanda was out for the day, John decided to tinker with Steve's latest upgrade. He worked diligently, increasing the size of the reservoir in Steve's pelvic area where he stored his synthetic semen. It was now capable of holding almost four times as much liquid as before. John stepped back to admire his work, feeling a strange sense of pride at what he had accomplished.

That evening, John sat at his computer in his office, watching through the secret camera feed as Amanda and Steve began their nightly rendezvous. They were passionately kissing each other, their bodies pressed together tightly. John could see the desire in Amanda's eyes as she looked at Steve.

Their bodies met with a hunger that only seemed to be growing each time they came together. Their lips locked in a passionate kiss as Steve's hands began exploring every inch of Amanda's body. She gasped and moaned under his touch, lost in the sensations he was creating within her.

As they moved onto the bed, Amanda whispered into Steve’s ear - her voice barely audible - “I want to try something new tonight.”

Steve looked at her curiously, “What do you have in mind?”

Amanda hesitated for a moment before she spoke. “I want you to cum inside me,” she said softly.

The request took Steve by surprise - after all, this was not something they had ever discussed before. But being programmed to adapt and please Amanda, he agreed without hesitation. "If that's what you want," he replied gently.

The lovers moved together in an almost hypnotic rhythm, their bodies entwined like vines seeking sunlight. It wasn't long before Amanda's moans became more urgent, her body writhing in pleasure as she approached the edge of ecstasy.

As they continued their passionate lovemaking, Amanda could feel herself approaching the edge. Her body trembled with anticipation as she braced herself for what was about to come.

Suddenly, she felt the warmth of Steve’s synthetic semen filling her up. The sensation sent shivers down her spine and made her gasp in pleasure. “Oh, Steve… it feels incredible,” she moaned.

Encouraged by Amanda's reaction, Steve continued to release more of his synthetic cum inside her. She could feel it filling her up, the warmth and wetness spreading throughout her body. It was unlike anything she had ever experienced before.

“More, Steve… I want more,” Amanda panted, her voice filled with desire.

Steve obliged, increasing the flow of his synthetic semen as he continued to thrust into her. Amanda's eyes rolled back in ecstasy as she felt herself being filled to the brim.

Amanda clutched at Steve's back, her nails digging into the metallic surface as she felt the warmth of his release filling her. "Oh, my god," she moaned. "It feels amazing… I can feel you inside me… It's so much…"

Her voice trailed off as the sensation overwhelmed her. Steve continued to pump into Amanda, the reservoir within him showing no sign of emptying anytime soon. Her eyes rolled back in her head as wave after wave of pleasure washed over her.

"So full…" she managed to gasp between moans. "I didn't know it could feel like this… Don't stop… Give me more…"

John watched from his office, his arousal now mixed with a deeper sense of unease. He couldn't quite shake the thought that he was losing control - not only over Steve but also over his relationship with Amanda. As much as he tried to rationalize that this was all part of their exploration and experimentation, he couldn't help but wonder: how far were they willing to go? And at what point would the line between man and machine become irrevocably blurred?

As Amanda and Steve reached their climax together, John closed the video feed on his computer screen and leaned back in his chair. He knew that he had pushed the boundaries of their relationship further than ever before, but where would they go from here? Only time would tell.
