Soul for a Girlfriend?

Lilith's POV

I was sitting beside Saishi who was lying on the bed with a flustered expression on his face, which he was trying his best to hide. The tip of his ears were slightly red, which was quite hilarious because it was the first time I saw him like that.

His neck was exposed as a bit of blood was smeared on the place I sunk my teeth into. He was genuinely horrified when he realised that I drank his blood. He was staring at me with his dark eyes, which were full of curiosity. 

It was rare to see him like that.

He was still breathing heavily, and his heart rate was pumping. The effect of the drug still had some time to wear down completely. Between the fist of his right arm, he was clenching the bedsheet.

It was a completely natural reaction for humans.

I recalled the moment how his body gave in to the aphrodisiac in my saliva and slowly lost control over his body as I sucked on his sweet blood. Even though I've tasted a lot of blood, he had a sweet scent to it.

I was teasing him a bit because it was fun to watch his reaction. It wasn't every day that I could see an embarrassed Saishi laying on the bed with red ears. He was quite cute, and I found it hilarious.

"Drinking human blood can save you from dying?" He asked me in his husky voice as I slowly nodded my head, "Not particularly… but you can say that."

It wasn't that drinking human blood would save me from dying. Or at least that's what he was thinking.

I was dangerously low on mana, which would've indeed led me to my end, but unfortunately I can't die. I have tried to take my own life in many ways, and running out of mana was one of them.

But I didn't die, just got caught in an endless abyss of suffering. But that's a story for another time.

I was low on mana, so drinking human blood was an indirect way for me to get mana. Even though it was quite simple, the process itself required some mana. I used the tiny bit of mana left in me to make that happen.

What I did was take his life energy and process it into mana, since mana was also a source of life energy and I could convert energy into different forms. But I didn't bother to explain all that, since it would be way too complicated for him.

I laughed awkwardly as I noticed him narrowing his eyes and pointing his index towards me, asking, "What was that though?"

I followed his eyes and noticed him staring at my fangs, which got exposed as I smiled. I pulled my cheeks with my left hand and showed him my sharp canines, "This?"

"I have never seen those teeth before!" He exclaimed with pure joy, but immediately repressed himself and gave me a cold look as I chuckled.

For him, it was like directly out of fiction where vampires drink the blood of humans.

"They grow out when I'm thirsty." I said, rubbing the tip of my fang with my thumb as he asked in confusion, "For blood?"

It was almost like how big cats unsheathe their claws before hunting. Demon's Teeth become unsheathed when they feel some sort of instinctual stimulus. For me, it was the need of mana where I was willing to do anything to get that.

"You know how your epiglottis moves asides when swallowing?" I said, pointing towards his neck, as it was a better example since it was referring to the human body. He nodded his head and replied, "You're really good at giving examples."

"I'm feeling better now." I said because I know he has been worried for me for the past few days, even though he sucks at expressing himself sometimes.

"I felt really weird." He said in a low and embarrassing tone as he narrowed his eyes at me and said, "Next time, give me warning before doing that."

"You'll feel like that either way." I chuckled as the effect of the aphrodisiac and anesthesia in my saliva will remain the same even if he is aware of what's happening. I shifted my eyes towards him as he looked away.

"You're having lewd thoughts, aren't you?" I said, as it was clear as day on his face. He was definitely feeling some sort of tension because of me. He looked back at me and nodded, "About you? Yes."

"That was straightforward." I laughed at him, being as blunt as ever. He was rubbing his neck with one of his arms and said, "That sting, it was your teeth digging in my skin."

"Yes." I nodded, and added further explanation, "And the pleasure you felt was because of the aphrodisiac I released in your bloodstream to make it less painful."

Slowly turning towards me, his eyes grew wide as he slowly spelled out those words with utter disbelief on his face, "Aphro...disiac?"

"What the fuck…"

"Don't look at me like that." I replied, showing him my palm while wheezing at his reaction as he sat up and looked at me like I just pulled the lamest prank on him. He said, "It was painful, just that the pleasure was overwhelming."

"Same thing." I nodded and dismissed his concern as he nodded instantly to strongly oppose my opinion and replied with a plain, "No."

I knew that after that day, he would never look at me the same way. It was the first time I did something like that to him and he looked quite horrified even though he calmed down pretty quickly.

The only problem with this method was that the person I'm doing it on becomes addicted to feeling that same pleasure again and again over time. If it comes down to that with Saishi, I would have to do something about it.

As for humans, the fluid in my saliva was literally drugs for them. And time has been the witness that stopping a person's addiction has been one of the toughest things for the person themselves.

And I again proved myself to be as terrible as I always was.

I just pulled Saishi into this trouble, knowing everything that would happen to him.
