29 experiment 02. (part three)

When checking Nine's Valkyrie file Sam was surprised to find nothing that could help him become her master. No hint was provided in the personality section.

She was described as the big sister type who cared for those around her. The file said that she would definitely make a good mother and wife, however it never mentioned anything about how to make her into one.

Sam had no idea how to go about making her his plaything, but he didn't have to think too hard about it. After all, she already came to him once with the intention of partaking in erotic acts.

"Doctor~♡" Nine said, panting as she smiled at Sam. "Does it feel good~?"

"A-ah, yes, really… really good…"

"I see~♡"

The Valkyrie was still on her knees, this time using her giant breasts to service the Doctor who was sitting on his chair, his pants having fallen off.

"But honestly, to think there are so many ways to stimulate the male organ." She said, bringing her attention down to his crotch, which was hidden underneath her chest. "Those two in the library didn't do this even once."

"Probably… because she didn't have... a chest… like yours…" 

Sam was having a very difficult time keeping his thoughts together. Though she was still wearing her tight combat suit, the softness of her marshmallows was still mind-numbing. 

"Now that you said it…" 

Nine's chest was way too large compared to that of the average female human. Most of the Valkyries had oversized breasts, however she was among the few who had such a comical size that couldn't possibly work for a normal human. 

They were so big that Sam's fully erect penis was completely buried between them. Nine had to lift them from below due to their sheer size, which took a considerable amount of effort, but seeing Sam's reaction increased her excitement and she was trying her best to make him cum once again.

It wasn't before long that the sticky white fluid erupted, and after a couple of seconds, it began filling her deep cleavage.

"A lot came out this time too~♡"

That was the third one, yet Sam didn't feel satisfied. After unloading that much his reserves should've been empty making it difficult to go on, but for some reason, his rod was already preparing for the next round less than a minute after he finished.

Wanting to make the last one count, Sam stood up and pushed the chair away. Nine noticed the state of his spear and knew it was already time for the fourth round. This time however she didn't have to do much herself.

Sam reached out with both hands and grabbed her gigantic milkers, their shape having changed a little with her nipples stiffening. He gave them a good squeeze and pressed them together, then proceeded to slowly insert his hard cock in the line dividing them. 

Watching him carefully, Nine straightened her back so she would be at a more optimal height. She remembered seeing something like this back in the library, although a bit different. And as if to confirm her guess Sam began moving his hips, gradually increasing his pace.

The Valkyrie didn't understand why but it felt different from when she was the one moving. Her heart was beating much faster and a certain part of her felt awfully itchy. Before she knew it her hand slid between her thighs trying to scratch that itch. It was then that she noticed how wet her crotch area was. 

Though the state of her groins was a source of confusion, Nine began massaging it. The next moment a new sensation washed over her entire body opening the dam and allowing the heat it blocked to flow out. 

"Ahh~♡ ahh~♡ mhaah~♡ ahhAAAHHHHH~~♡!!!"

Her fingers moved in accordance to Sam's pace and with a last thrust the two of them climaxed at the same time. 

Sam held on to Nine's massive juicy melons as his rod pumped the sticky white substance between them. Nine was panting uncontrollably, her mind a bit hazy as her secret trench continued squirting a clear liquid, creating a small puddle under her.

"Haa~~h~♡…" 

Pulling her hand from between her legs, the blonde Valkyrie looked at how drenched it was. Sam, having ejected his thing, backed away to catch his breath. When he let go of the giant marshmallows the sticky liquid trapped between them flowed down her stomach and onto her thighs. It wasn't his intention but the Valkyrie was now covered in his semen from head to toe.

"I see you came as well…" he said, noticing her stained hand. 

Nine tilted her head at him, not understanding what she was talking about.

"Um… how do you explain this…" Sam stopped to think. It was another thing one usually didn't need to explain, but he tried his best anyway. "Remember how your muscles tensed up this entire time, especially around your… well, down there…" he said, pointing at her nether. Nine followed him with her eyes which widened the next moment as if she understood what he meant. "Cumming is when that tension gets released. It's also called climaxing."

"... it felt… so~ go~od~♡" Her entire body seemed to melt, finally relaxing now that she knew the leak wasn't a cause of concern.

"Is that so?" 

It was impossible to know if the Valkyries actually felt sexual pleasure, as they aren't exactly human. According to the Frejya file, they were all made to be the best sexual partners. Their bodies are programmed to react the same way a normal female would, which means that at the very least they should be able to recognize how they're supposed to feel when experiencing the right stimulation.

That was what made them so different from the average sex doll. Doing it with a Valkyrie would surely feel like doing it with a real woman, although many times better. 

Excited to move on to the main dish, Sam turned to look at the terminal and reality immediately hit him.

"Let's end it at this for today." He said, his shoulders slumping. 

They have already run out of time. 

"Eh!!?" Nine looked up with a start, her expression turning sour. "But we have yet to-"

"Let's leave it to another time. You still have to go through your examination."

"Then how about we continue after?" 

Sam stopped to give it some thought as he cleaned himself and pulled his pants up. In the end, he could only shake his head, a regretful sigh escaping him.

"No, it would be for the best if we leave it for another day."

After ejaculating four times it was inevitable that he would go into sage mode. The idea of going on after the examination was appealing, but he had something else in mind for when he would eventually cross the line with Nine.

First, he needed a bed. He wanted their first time to be somewhat special so doing it in the lab felt a bit lacking. Also, he wanted to go at it for a while without having to worry about time so it would be ideal if they could meet at night. That said, fulfilling those conditions didn't seem like an easy task. It would be impossible to sneak her into his room without anyone noticing, and humans were prohibited from entering the Valkyrie's quarters so he couldn't go there himself. 

'Maybe I should just ask her to come here after dinner time…' Sam thought as he considered his options. In the end, he decided to worry about it at a later time.

"... understood…" Nine began to sulk. She used a towel to wipe herself then returned it to Sam who threw it in a bag immediately.

As she walked to the other room, Sam reminded her to keep what they did a secret just in case. The examination ended a few minutes later and the three Valkyries left like usual, as if the short session from before never happened. Sam moved on to editing the examination results, erasing anything suspicious from Nine's file as well as Zero Five's, since they continued to make out after yesterday's report was sent.

With that, the second experiment came to an end. With a woman satisfying his urges for the first time in more than a year, Sam leaned in his chair and stared at the ceiling, his mind replaying scenes from his steamy encounter with Nine.
