When Sam placed his hands on her shoulders, Zero Five's body jolted a little. He had expected such a reaction and moved slowly, carefully, doing his best to make her relax.
He gently caressed her exposed skin, its softness amazed his mind. Sam didn't touch every woman out there, but he knew for sure the smoothness he felt right now was unmatched.
Just like her hair, Zero Five's skin was similar to a human's. The warmth coming from it felt natural, with the temperature of her body slowly rising from excitement. He couldn't help but think, once again, how amazing Odin was for managing to create something like this. The man didn't joke when he said he would recreate the entire female body. Truthfully, he went even beyond that as no real woman could hope to achieve this beauty through natural means.
No doubt he thought that, since he was doing it anyway, he might as well make them better in every way. Since they were intended to be a replacement for women as romantic and sexual partners, Sam was sure that doing it with the Valkyries would be as good as it could get.
'I need to calm down...' He thought, noticing his growing excitement. 'One step at a time. Who knows what kind of mess this might create... I need to stay patient.'
He had only touched her shoulders so far yet his whole body was demanding he spread her legs already. Unfortunately, the time he had was limited and there was only so much he could do before it ran out. He had to try the few things he decided upon beforehand and the rest would have to wait for another time.
Moving on to the next step, Sam grabbed Zero Five's shoulders and pulled her toward him. Surprised by the suddenness of his action, the Valkyrie looked behind her only to turn away blushing when she saw the Doctor's face so close to hers.
The cuteness of her reaction warmed Sam's heart. He always thought of her as the cool beauty who is never fazed by anything, but now that he got to see this side of her, he realized that the things written in her file were pretty accurate.
In the personality section, Zero Five was described as an extremely shy girl. She doesn't know how to start conversations and is bad at keeping them going. The way she carries herself causes everyone to think she's just a quiet and serious person, but in reality, she's just bad with people and the only way to see through her stoic act is to get close enough to become her master.
'Does this mean we are that close?' Sam thought as he felt her back on his chest. 'She wouldn't have allowed me to touch her like this otherwise...'
Sam was just a little taller than her. Though he was a bit skinny, his body was toned enough to show the contrast between him and the Valkyrie's feminine form.
As he looked from over her shoulder his target came into sight. Though they weren't as big as Nine's, Zero Five's breasts were larger than those of the average woman, and since they were compressed inside her tight battle suit, he was sure they'd be even bigger once they were released.
With his hands having stopped shaking a while ago, he had no trouble reaching for the ripe fruits hanging in front of him.
Same as before, Zero Five's body tensed up when a part of her got touched for the first time. Sam carefully moved his hands on the surface, gently caressing the massive melons until she calmed down. Only when he heard the sensual hot breaths she was leaking did he allow his fingers to slowly dig into them.
"Ah!"
For a moment there he was left stunned by the elasticity of the two buns which prompted him to squeeze them again. Five's heated gasps excited him more, and before he knew it, his hands were kneading her chest as he made sure to enjoy every moment of it, the softness not having betrayed his imagination.
Looking from afar one would think they were just balloons full of air, but Sam now knew that wasn't the case. They were as thick as one would expect from a woman's breasts, and when he lifted them from below, he learned how heavy they were. According to the blueprints, they are even capable of producing milk.
He wanted to free them from the tight suit so he could feel them better, so he could get a taste, however today wasn't the day. Besides, fondling them like this felt good in its own way.
"Ah~.... ha~hh… mmn… aahhnn!"
Zero Five's moans grew louder each time he put more strength into his hands. He watched the shape of her chest change as he squeezed it, knowing he could keep doing this all day and not get tired. Still, in the interest of time, Sam decided to move on to the next thing he wanted to try, and so with a final squeeze, he slowly let go of the massive melons and moved his hands away.
He allowed a few seconds for Zero Five to catch her breath. She turned to look at him, her face flushed, her eyes hazy and almost closed. Such expression was so alluring he almost had his heart stolen and that gave him a little fright.
Before he knew it, Sam began to fear that if he wasn't careful enough with his experiments, he might end up falling for the Valkyries. Many already did without ever getting to see them up close and he wasn't about to believe he was an exception. To ensure it never gets to that, keeping a straight mind and remembering that they were robots was the only way.
"D-Doctor…" Zero Five spoke, stopping to take a deep breath before asking. "Are we… are we done with the experiment?"
Sam stared at her for a few seconds enjoying the way she looked at him. Smiling, he then placed his hands on her shoulders and turned her around before pulling her into his embrace once more. "No." He said, feeling the warmth of her chest as it got pressed against his. "Not yet."
His hands moved on to the next item on the list, starting to play with the Valkyrie's bottom hills. From the way Zero Five reacted, it seems that part of her was much more sensitive. The stimulation was so strong that she started to pull on his shirt, resting her head on his shoulder as she struggled to hold back her moans.
It seemed like she was about to climax at any point now, but Sam didn't want to end it; he had yet to have everything he wanted from this experiment. Relaxing his hands a little, he thought about what he should do next, and when Zero Five looked up to see why he stopped, the idea came to him right away.
Without hesitation, he brought his face closer to hers and joined their lips.
Zero Five's eyes went wide, the shock causing her whole body to go stiff. She didn't know why but having her lips touched by his felt much more impactful than everything they did so far. Her chest was filled with warmth in an instant turning the surprise she felt into a desire. Closing her eyes, she submitted herself to the man and began to enjoy the sensation, paying no mind to the world around her.
Separating only for a moment, Sam kissed her again. Not long after he got his tongue involved, pushing it inside her mouth and tangling it with hers all while playing with her ass.
When he finally let go of her, Zero Five seemed to have lost her senses, staring blankly in a drunken state. It was her first time experiencing such a sensation and it quickly forced her into a state of ecstasy. A couple of seconds later she snapped back to reality and her face flushed with shame.
Sam leaned in and kissed her one more time. Though he wanted to continue, time dictated that this would be the end of their experiment.
"Is it… is it over?" Zero Five asked, holding a hand to her burning chest.
"Yes. This should do for today." Sam said with a nod. "Now, we better start your examination. Remember, we don't want anyone to learn about this."
The examination wasn't on a timer so it wouldn't end until he did something on his side. Though that meant they could go on for a while longer, Sam was worried that the other Valkyries would wake up and think something was off, and delaying his report too much might alert the headquarters.
Zero Five looked a bit disappointed, but that lasted for only a second. She soon regained her calm expression, though her cheeks retained some of the red color that tainted them for the past few minutes. Nodding once she turned to walk toward the other room. As he watched her go, Sam noticed that a certain part of her was soaked and that put a smile on his face.
Once the last container was sealed and the viscous green liquid enveloped her, Sam sat down in front of the terminal and cracked his knuckles.
This was the part where the real work began.
