Once he finds out what it is, maybe

"Speak!" He instructed the shivering demon beneath him, while learning first hand that succubi could indeed cry.

"I share my source with you." she whispered, sobbing. John knew he had broken her. The plain fear of **** had probably also cost Layklé her sanity, but he didn't care about that now.

"Explain." Another shortly given command and yet another whispered obedient reply.

"I will form a link to you. You will gain parts of my powers. The stronger I become, the stronger you become. But it also makes me gain strength slower than normal. I will be forever bound to that speed, even after your ****." John nodded. This sounded more pleasing to him.

"How do we form that bond? And can it be broken?" He asked, which resulted in another silent sobbing. Had she hoped he would deny this offer as well? Stupid girl. If she would have thought of it, she would have known that there was no reason to.

"By you drinking my blood. And it can only be broken if we both want it to be. Which means even after you die, I will be kept weak and my power will be drained away by Gaia, slowly killing me." Great, so he could be certain she wouldn't act out and betray him. That was if she was telling the truth. All his instincts were telling him she was, but when dealing with abyssal monsters, or anything from the abyss, as Henrietta had proven, his instincts were not to be trusted completely.

He cursed himself for the need to do this, but he cast yet again, an overcharged deal with the devil before restating.

"You will share your powers with me in an extend of relation to your own ability strength. You will die shortly after I die. This agreement can't be broken until it is of mutual wish to do so. The only thing you gain from this is that I agree to not **** you right now. Is that correct?" He repeated everything. Even if her statement before was a lie, once she agreed it would become the truth, undoubtfully.

She chuckled, which looked really weird considering she was still shaking and crying at the same time.

"I agree to your contract." She said. The small sigil, this time a purple one, appeared on her left tit. A fitting place. John however had no eyes for it as he raised his brows.

"How did you notice what I did?" She chuckled again and stood back up, just after John had let go of her. There was no more danger coming from her, unless she was suicidal. Especially since she knew she was bound to her word.

"I am a succubus, boy." John frowned. He considered his encounter to be succesfull and he had just defeated her. So she should at least show some respect to her new master! "We have a high affinity to magic. After all, every bit of energy we consume, we strengthen it by turning into pure lust that we first store in our bodys, so we can send it to our targets later. And magic is no different there." John took a step back. Shit. Had he just fed this monster with a super loaded gun of energy? And even worse, he had done so by using not only every mana he had, he also drained his mana regeneration for the next minutes along.

"Fuck." He cursed and Layklé smiled triumphant at him.

"Oh, don't worry, boy. We will." She looked into his eyes, knowing full well that the tables had turned in this battle once more.
