Chapter 153 Upgrade.

Before he knew it, Sam found himself in Nine's room lying down on the bed with her on top of him.

Seeing how she was panting with that ecstatic look on her face he realized that he might be in some serious danger.

"Doctor... I... I want you to-"

She was about to dive down on him going for another kiss, however before she could he blocked her with one hand.

"Nine, cut it out." He said, his expression deadpan. "That's an order."

"But! Doctor!"

Just then Three and Five appeared in the room as well and seeing how their comrades was practically attaching the Doctor they quickly pulled her away.

"Nooo! Doctor! I want to do it with Doctor!"

As Five held her in place, the blond Valkyrie kept reaching toward Sam with both hands. Thankfully things didn't have to get violent and she calmed down soon enough.

"Just to be clear, Nine." Sam spoke, attempting to adjust his glasses just to realize he wasn't wearing any. "I'm the one who decides who and when I do it with. Never forget that."

"... yes..." she replied, her head cast down. "I wanted to be with Doctor, that's all..."

"You have to be more disciplined and control your urges. Failing to so so means you aren't worthy of being my personal Valkyrie."

"Eh!!? Doctor! I'm sorry! I didn't mean to be disrespectful! I will be careful in the future so please don't demote me!"

Sam had already known for some time now that Nine has a much stronger sex drive than the others. Going forward he planned on increasing the size of his harem as much as possible, that would inevitably lead to her time with him decreasing and the same goes for the others. He didn't want her to end up in another man's hands just because she's unable to control her carnal desires.

He stared at her for a few seconds wondering what he should do then closed his eyes and exhaled.

"As a punishment." He said, taking off his drenched clothes piece by piece. "You will watch everything from the sides until I say it's your turn."

"Eeeeh!! But-"

"No buts." Sam cut her before she could complain, walking over to Zero Three and placing his hands over her shoulders. "Besides, Three is the one who saved my life that day. If anyone deserves to go first then it's her."

While the young Valkyrie was blushing to her ears, Nine was completely silent at that statement, her body losing strength causing her to fall to her knees.

"I... I understand..." she said, her soaked hair and clothes making it look as if cold water was really poured on her.

"Five, lock the door." Sam said. He didn't want the other Valkyries to have the chance to peek, though with how they're able to teleport anywhere he didn't know if doors meant anything anymore.

"Alright then..."

Moving away from the young Valkyrie, Sam looked down at his pants and took a deep breath. He glanced at the three Valkyries one more time then proceeded to unbuckle his belt, and once he had everything removed be looked up again to see the shocked expressions on their faces.

"D-Doctor! What happened to your-"

"You already know that I'm no longer the same as before, right?" Sighing at Nine's newfound excitement, Sam looked down at his erect meat pole. "Well, Elina thought it would be funny to mess around with some things and this is the result."

Sam was never bothered by the size of his dick, one could even say he was proud of it considering how many women he managed to satisfy. It wasn't small by any means, however compared to how massive it has become his previous size pwasn't much to speak of.

Just by looking he could tell it was over nine inches, and the thickness only made things worse.

Any man in his place would've been happy to undergo such an upgrade, however to Sam it felt like a huge hit to his pride. Still, a part of him was looking forward to using it but when he turned to the young Valkyrie he saw that she had stepped away from him fidgeting nervously while trying to keep her eyes away from his tool.

"Three?"

"I-I-I think I'll just watch for now!" She said, walking over to Nine and sitting down.

'Ah!'

It was only then that he realized his new weapon was almost as big as her forearm. For a girl with a body as petite as hers it made sense for her to be scared of something of that size going inside her. Nine on the other hand looked rather excited, but the smile she wore disappeared the next second as he turned to Five.

The ponytailed Valkyrie looked as nervous as the young one, however she didn't allow it to hinder her and immediately began taking her clothes off.

Her eyes didn't leave the meat pole as she stepped toward him. When she looked up he was surprised to see that that pink hearts had already formed in her eyes.

He pulled her toward him and stole her lips, going for a deep kiss right of the bat.

Five closed her eyes and intertwined her tongue with his, warmth blossoming in her chest like sparks igniting her passion for him.

Though he wanted to enjoy the kiss a little more his rod twitched demanding he shares the softness of the Valkyrie's lips.

When he went and sat on the bedside Five knew what she had to do, walking over and taking her place in front of his rod.

"Doctor's... It's so..."

She stared at it for a while, her eyes half open as if she was in a daze. She ran her fingers from the tip all the way to the base. Not knowing how she should go about holding it she tucked a stray strand behind her ear and leaned in with her tongue out. The warm breath should've been a clear enough warning, but when the slippery surface stroked the tip Sam's whole body shivered, the sensation increasing a thousand folds when she took the thing into her mouth.

Sam had to actively stop himself from making any sound as he came to a realization. Suze wasn't the only thing Elina had messed with. All it took was a few brushed of Five's tongue and lips for him to realize that the female scientist had cranked up the sensitivity of his rod a few times.

Less than a minute in and he was already on the bring of ejaculation. Though she tried Five soon learned that she couldn't shove the entire rod inside her mouth, not without it going all the way down her throat. Knowing that's her limit she began bobbing her head causing a more intense wave of pleasure to flood Sam's nerves.

He reached out with his right hand about to tell her to slow down but when she looked up at him with those pink hearts in her eyes he chose to let her continue only patting her head instead.

Three and Nine sat on the floor watching from the other side of the room -which wasn't that big-. It became clear that the scene was getting into them as they fidgeted in their place with their hands between their legs as they rubbed against each other.

Three was confused at first, however from what little she knew about the deed she soon understood that there might be more than one way to pleasure a man's rod and was reminded that the deed wasn't just about that thing penetrating her body.

​ Having made up her mind the young Valkyrie nodded to herself before standing up. She quickly removed her swimsuit and faced Sam with a serious expression then before the embarrassment got to her she made her way to his side. Sam welcomed her with a smile and without hesitation pressed his lips against hers. He felt her nervousness through the touch of her skin; the two of them barely had any intimate moments beside the time he made love to her for the first time so it only made sense for. That said, as their lips overlapped he could tell she was trying to convey her feelings to him and that helped him savor her cuteness even more.

"Ah~ D-Doctah~... mnn.. ha~hh~♡..."

Three made some really cute voices, her body shuddering each time he stroked her behind. His fingers eventually found their way to her secret flesh. Rubbing it caused her love juices to flow as her body froze, but Sam took that opening to invade her mouth coiling his tongue around hers and making contortive sweeps of her mouth's vault.

Down below, Five didn't seem to like the fact that his attention was taken away from her. With a slight frown she became more aggressive, running her tongue along the long shaft, sucking at the base while using her hand to stroke it up and down with such vigor it felt like she was about to rip it off. She was trying to make him cum faster but Sam did his best to hold it in. That didn't last for long though and soon after she gobbled the rod once more he held her head down shooting his load deep into her throat.
