Valkyrie Smash

Miku's eyes shot open, the sudden sharp pain forcing her to realize she had made a really big mistake.

In less than a second Sam's spear tore through her insides reaching all the way up in one single motion. Her whole body went rigid from the shock, her mind halting as it struggled to comprehend what going on. She already knew Sam's penis was massive, however only now that it was inside her did she understand what it means to have sex with him.

Sam wasn't having any better time. Miku's virgin pussy was so tight it felt like the pressure was about to crush him.

Gasping as if she had just remembered to breathe, Miku collapsed forward panting while her whole body trembled from the pain.

"M-Miku... are you... are you alright?" Sam said, slowly lifting himself using his elbows as supposed.

The first thing he saw was the Valkyrie's behind, her soaked vagina spread to its utmost as it swallowed his thick rod whole. Having already done it with Nine and the others Sam knew that the Valkyrie's sexual organs adjusted to match his new tool, however this was Miku's first time so he wasn't completely confident that she is unharmed.

"Miku?"

Receiving no response only made him panic even more. He pushed himself into a sitting position, careful to move his lower half as little as possible, but that caused the blond one to groan telling him she felt it.

"Miku, are you hurt?"

His question was met with silence again. This time however the Valkyrie began to move, gradually lifting herself up with shakey arms before turning around to look at him.

"I'm... haahh... I'm fine..."

The tears that had gathered in the corners of her eyes were evidence of the pain she was going through, but her flushed face and the heart shapes in her eyes told a different story. Somehow the expression she made came off as extremely erotic and in just a few seconds the fear Sam felt was transformed into arousal.

"You should've been more careful." He said. "That's not something you do on your first time."

Another negative effect porn had on the Valkyries. He made a mental note to personally teach safe sex to each and every one of them then brought his attention back to the one in front of him.

"But..." pausing for a moment she followed in a small voice "I want to... I want to make Doctor feel good..."

Miku has always been a little aggressive compared to other Valkyries, with Nine as the exception. She took every chance she could get to show her feelings toward him and that extended to wanting to please him with her body.

That said, sexual pleasure goes both ways and Sam wanted her to focus on enjoying her first time instead of worrying about him.

"Miku, can you move?"

The Valkyrie remained silent for a couple of seconds before looking back at him.

"My legs..."

Having guessed as much, Sam grabbed Miku's arms and carefully laid her on her right side. He considered taking his meat pole out but decided it would be pointless since he would be going in again soon after.

Lying down behind her he brought his face close to hers and took her lips. He savored the kiss for some time before looking into her eyes.

"Miku, you don't have to worry about me." He said, gently wiping the tears from her eyes. "This is our first time together so it's important that you enjoy it as well."

"But..."

"It's okay. Let me handle everything from here. I'll make sure you'll have the best time of your life."

Sam joined their lips again then reached down with his left hand, grabbing Miku's leg from behind the knee and slowly pulling it up.

"Ah!!"

"It's okay. We will do it slow and steady."

Having her legs spread apart allowed the young Valkyrie to see where their private parts connected. For some reason that filled her with unimaginable shame, which only grew stronger when she glanced up at the Doctor.

"How do you feel, Miku?" Sam asked. "Is the pain gone now?"

When their eyes met she quickly averted hers, feeling even more ashamed. She wanted to act strong and do her duty as his personal Valkyrie, however she ended up embarrassing herself and having him take care of things for her.

"It's... it's gone... almost..."

"I see..." having noticed how she was being shy, Sam smiled to himself. "Well then, I will start moving slowly. Tell me if the pain becomes stronger, okay?"

"Um... okay..."

The truth is that Sam was nearing his limits as well. He wanted to get to the act as soon as possible but held back for the blond one's sake, afraid to hurt her again.

"Unhh... ahh...

He slowly pulled back watching Miku's reaction all the while. He noticed her body stiffening. She was clearly having a difficult time, but with no complaints coming from her he continued at the same pace.

"Miku, you need to relax." He said. "We're already past the difficult part. There is nothing to be afraid of."

Having something so massive invade her insides made for a terrifying experience, even if the Valkyrie didn't want to admit it herself. Sam was careful when pushing in as well. Once he reached all the way in he would stop for a few seconds then start pulling back again.

"Haah... ahh... ah... ahh... ahh..."

It was a slow process but thankfully Miku seemed to be getting better so Sam sped up. He used his free hand to massage her small breasts, then when he caught her glancing his way he leaned in for a kiss.

"Doctor... ah... hahh... Doc...tahh~♡! Mnahh... ahh... mnmm~♡!"

After a while Sam no longer had to pause between each motion. His thrusts became more aggressive and Miku's moans grew louder and louder. The massive rod that caused her so much pain was now a source of pleasure. She was having sex with the Doctor. She has finally achieved her wish of doing the deed with him and that caused her chest to overflow with happiness.

"D-doc...tah~♡ I'm... ahh~♡! I'm doing it... hah... I'm having sex with Doctor~♡! Hah... ah... hahh... ahh... this is... sex.... This is... ah... this is sex with... Doctor~♡! Hah... so good~♡... sex with Doctor... so good~♡!!!"

Thinking it was time to end it, Sam sped up once more. Miku gasped as her nerves were flooded with the stimulation from her hole, and before she know it she was on the verge of cumming once more.

"Doctor~♡! I'm... ah~♡!... I'm cumming~♡! I'm cumming... Doct... aaaAAAAAAAAAHHHHH~♡♡♡!!!"

Sam let go of his restraints and the two of them climaxed at the exact same time. His cock, which has been pushed to her deepest part, began pumping loads and loads of his fresh artificial cum. Before long Miku's womb was filled to the brim. The young Valkyrie had noticed the warm liquid as it gradually filled her, and having read something similar in that book she immediately that the Doctor came inside her.

"Hahh~♡... Doc... tor~♡..."

Seeing the satisfied smile on her face informed Sam of the way she felt. Smiling back at her he went down for another kiss. Now that they had their first time together Miku was finally on the same level as the others. She could finally proudly declare that she is his personal Valkyrie, but that was a matter for another time.

Right now, all that's on her mind was doing it all over again, and knowing that he can take on multiple Valkyries at the same time, Miku was sure she was in for a long night.
