Vampire Cultivation System in a Hidden World of Monsters

Mira and I just got right to it. She was rearing and ready to go. By that, I mean her pussy was wet as fuck. She really was a little fuck bunny. She threw her arms around my neck, lined her pussy up with my cock, and just slid herself all the way down.

She went balls deep on me, just like that. By that I mean I was balls deep in her, but she was the one who did the work, not me. By pushing against my hips with her feet, she started working herself on and off my cock.

I kind of just let her do that for a bit. It was incredibly hot to watch and feel, and the balance part wasn't hard. She was a pretty heavy person despite her lean, fit body, because her limbs were made of metal, but I was just that strong. It took a lot to knock me over.

She was really working my cock. I was tempted to bust, but she had waited so long, I didn't want to end it too soon and not give her the time she deserved. I'm not saying I wouldn't be able to keep going after cumming. I'm saying she probably wouldn't, as all the girls before her didn't.

"Why haven't you cum yet?" She said. "Am I not sexy enough for you? I'm working your cock like a god damn cheetah over here."

"You want me to cum? I've been holding back. I don't want to make you pass out like the other girls, before you get your time in," I said.

"You think I'm like the other girls?" She said, looking me in the eyes as she worked my cock like a pro. "I've had all of my limbs replaced. Which were perfectly good limbs by the way. And I have a cybernetic enhancement in my spine that hyper stimulates my nervous system. You don't think any of that hurts? Cuz it does. A lot. I can handle it. Just cum inside me, I'll absorb your cum and we'll get back to it."

"If you're sure. Let's exchange blood first, just in case," I said.

"Ok," she said.

I bit my arm and put it up to her mouth, and then bit her neck. She bit extra hard onto my arm. Far harder than she needed to. Then she started sucking my blood. I sucked her blood nice and steady. Then the system notification came.

[New Vampiric Evolved Ability Acquired: Neural Fortitude: Novice]

[Neural Fortitude: Reduces neural strain and increases neural endurance capacity, including pain tolerance]

[Mira's Vampiric Type: Neural Vampire]

[Feeds off the neural exertion of her opponents in combat and the neural pain caused by the damage she inflicts on them]

'Thanks for anticipating my questions.'

[No worries, broski]

'Getting better.'

Wow. This was going to be game changing! Not just for me, in reducing how often I pass out from overexertion, but also for reducing the neural damage caused to Mira every time she uses her neural acceleration enhancement.

I was sure at Novice level, Neural Fortitude would help a significant amount, but I doubted it would negate Mira's ability to die, or die again, from neural overload due to overuse of her enhancement. While Mira thought being undead would prevent her death from the neural enhancement, I wasn't so sure.

That said, when she absorbs my cum, it will boost her Neural Fortitude ability significantly. That was interesting. By not passing out when I cum inside her, she will increase her resistance to passing out from me cumming inside her, and then if I do it again, it will further increase her resistance, and so on, into infinity.

It was an interesting feedback loop. She just had to handle this first time and she was basically home free. And then I could cum all I want inside her and she would just keep absorbing it and getting stronger.

I couldn't wait to cum inside her, I mean, power her up. I relayed the information that the system gave to me, to Mira.

Then she said, "Ok, what are you waiting for? Cum already!"

"I will, I'm just going to lay you back on the bed before I do it so I don't get pushed out," I said as I laid her down on an empty bed. I pressed my cockhead into her cervix when I laid her down.

"Ok," she said. "Now cum, bitch!"

"Ok!" I said. I had been holding it back for so long, it was going to come in a torrent when I released it. So I released it. "Oh fuck!!! I'm cumming inside you, Mira! Oh god!! Unh, unh, unh!!"

With my cockhead fully inside her womb, I let the first shot loose. The first spurt ballooned my cock as it worked its way up. When it released inside of her, her stomach immediately ballooned outwards.

"Oh fuck!!" She said. "That's so good!! Give me more!!!"

I let loose another shot and another. I just kept cumming. By the time I was finally finished, her stomach was bigger than the mass of her whole body. But she held on like a trooper.

"Oh fuck!!! That's so fucking good!!! I'm literally continuously cumming! Oh fucking fuck!!" She said. She clenched her teeth and tried to will herself to absorb the cum.

I wasn't sure it was going to work like that, but as soon as she did that, her stomach started shrinking. In a matter of seconds, her stomach was petite and flat and chiseled with her small feminine abs once again.

[Detecting… Mira's Neural Fortitude ability has increased from Novice to Transcendental!]

'Wow. Even you sound impressed.'

[I am!]

'Nice.'

"Ok! Hop on me baby!" Mira said, as she turned over and stuck her ass out at me. "I want you to do me doggy!"

Her literal love handles popped out of the back of her hips, just begging me to grab them. If I wasn't already rock hard, I would've gotten rock hard from how sexy what she just did was.

I grabbed her by the love handles and lined my cock up with her pussy. Then I slammed myself into her as hard and as fast as I could. My cock plunged all the way into her womb in one go.

"O-o-o-o-o-h fuuuuuck!!!! I'm cumming again!! Shit!! You feel so good, Dylan, fuuuck!!" She said.

"That's right, baby. Cum for me!" I said, all confident and shit. I felt like I was on top of the world.

I pulled out of her womb and thrust all the way in again, but I didn't pull down super hard on her handles. I just pulled and thrusted enough to where our hips clapped together.

When I did that, my cockhead just kissed her cervix. I didn't want to overload her with constant womb action. I wanted to save that for special occasions.

So I pulled at her handles and thrusted and built up a good rhythm.

"Oh fuck, dylan, fuuuck!! You make me cum so good!" Mira said. "You can cum though, baby. I know you're ready. I know you want to. Just cum. I can handle it."

She was right, I had been subconsciously holding back my orgasm again, thinking I had to give her a fair amount of time, but I should have let it go more naturally. Just cum when I'm ready to. So I did.

I slammed my hips in hers and pulled up on her handles. My cockhead invaded her elasticized womb. As I started cumming, holding her by the handles against my hips, I stepped back away from the bed. This pulled her off the bed but kept her feet off the ground.

She was dangling, attached to my cock. As I came, her belly swelled. I pulled away from the bed because I wanted to give her stomach more room to grow. The more I came inside her, the more powerful her neural fortitude would become.

I was operating under the assumption that when her neural fortitude reached a certain level, it would cancel out the fatal aspect of her neural acceleration enhancement.

So I wanted to be able to cum as much inside her as I possibly could, to try to get her Neural Fortitude over that threshold. I was basically cumming inside her to save her life.

I was still enjoying it sexually, but saving her life was the goal. And I won't say making her belly massive from my cum wasn't hot as fuck to me. It was. Just the idea of it made me cum harder.

So by the time I was done cumming, she was basically laying on top of her now massive belly.

"It's sooo much, Dylan!! I know I said I could handle it, but I think I'm gonna pass out," she said.

Her head started to fall down, but I grabbed her head by the hair at the base of her skull and pulled. Hard. I leaned into her ear and said, "Don't you dare fall asleep until you absorb all the cum, young lady. For safety reasons, but also because I said so!"

"Yes, Dylan! I'll stay awake until I absorb your cum!!" She said.

She closed her eyes and started concentrating. Her stomach started to shrink and shrink. In about half a minute, she had absorbed all of my cum. I lifted her off my cock and set her face down on the bed.

[Mira's Neural Fortitude has reached the Divine level!]

As soon as her head hit the pillow, she was out. One more down. One more to go. I turned to look at Alice.

"Hey, I like a cum bloated stomach as much as the next girl, but I can't handle that much. I'll get stronger the slow way, one normally bloated stomach at a time," she said.

"That's fine," I said. "You still do want to have sex right?"

"Oh, absolutely! Oh and I've been thinking about positions. I think I want you to fuck me in the walk in shower. I'll put my hands against the wall and lean forward, and you just ram me from behind," Alice said.

"Sounds good to me. Let's go get warm in the nice hot shower!" I said as I walked into the massive bathroom. Alice followed shortly behind.
