9 Chapter 9 Commissioned by Warslick Alt POV

Serafall Levithan was a woman who knew what she wanted in life. She was one of the strongest devils in existence and was within the top thirty strongest beings in the world and well into that list. She had stood on a mountain of corpses to get where she was and all she wanted these days was for devils to quit making trouble for her as the devil's head of foreign affairs and one last thing.

She wanted her sister...

As her adorable sister Sona stared down at her angrily with her soaked thong showing under her ultra-short skirt she could still see the splatters of Jake's white semen on her pantyhose and panty-covered mound as she gracefully stood up and took a seat in front of her sister uncaring of her nudity and disheveled state.

"So my adorable Sona, you are moving... Very fast to secure Jake to your side?" Serafall spoke while folding her arms under her large breasts Inadvertently pushing them up and making Sona glance at them and although Serafall was inwardly preening at the measuring glance her beloved sister took at her breasts she didn't any sign of noticing her glance.

Sona flushed at her sister's point but she gamely put on a serious and businesslike expression of stoicism but her control over her expression couldn't hide how her cheeks were still pink at her sister's words. "And so what if I am? Didn't you yourself offer to take him into your peerage?" Sona pointed out and then sniffed.

"I am merely using my wiles to make Jake attached and more pliable to my desires," Sona said seriously but Serafall only raised an eyebrow before leaning forward and before Sona could react she swiped her finger across her sister's crotch making her jolt and moan at the abrupt pleasure and then Serafall stuck that finger into her sister's mouth and then Serafall's eyes widened as she could feel with her potent magical senses that Sona's magical depths actually grew slightly by ingesting Jake's semen...

So Serafall did the obvious thing and then used her other hand to swipe a bit more of Jake's remains to taste it and she couldn't help but blink at the honestly not-at-all-bad slight vanilla flavor... Then she felt her own prodigious magical energy grow by what felt like a whole percent.

Which for her was massive! Sure in terms of power numbers, a single percent of a hundred was nothing, but what if her power level was like a million or a billion? Her growth not only was in the depth of her power but she could also feel her control over her magic growing, so she just eyed her sister who had wordlessly moved her head back to remove her finger from her mouth.

"Sona... Jake is too valuable for you to be wishy-washy." Serafall said bluntly and Sona flinched at what her sister was hinting at. "You already used a stronger magician pact to bind him to you. But with his inevitable power growth to say nothing of him just up and leaving this world, losing him would be..." Serafall couldn't even finish the thought as it was worse than some human tearing up some mega-winning tax-free lottery ticket after thinking the numbers were wrong.

"Sona, as a Sitri I am asking you formally if you are going to make a Solomon contract with him... If you cannot, I will seek him out in order to teach him the Key of Solomon to bind devils to himself to gain their powers and in turn with him inevitably falling in love with you or maybe even myself we will grow in power." Serafall explained as she blushed at the thought of actually losing her virginity.

While deep down... A hidden thought was born of having Jake fuck that bitch Grayfia who she would swear to the deepest of hells was still looking at her position of Levithan!

The Key of Solomon was a ritual that Lucifer created when he saw how god favored Solomon so greatly and desired to bring that being that didn't even seem to be human to depravity. He created the Key of Solomon that would act as an internal core within the person that would grant them the devil clan's power that signed the contract of fealty and in doing so Solomon became the strongest human to ever live... Until he just disappeared somehow and the contracts were voided before he could be turned to the devil's side.

"I... Is that really necessary?" Sona whispered blushing as she was well aware of what signing the contract meant. She would have to have sex with Jake and his semen would act as the seal to the contract and binding Sona's form to his being.

Serafall solemnly nodded while mentally cackling with joy as Sona flushed and after a moment shyly nodded before her hands came together. "I don't think I am ready for that yet though Sera." Sona continued whispering but Serafall leaned over and gently took her sister's hands into her own.

"Sona I swear I will be with you all the way, it's in our very blood to do this kind of thing and we can even blindfold him or something to make this easier on you." She consoled and Serafall couldn't help her thighs quivering in need as she saw her sister bite her lower lip and nod in agreement.

She did it... She was going to coach her sister through losing her virginity! Oh, wait... She herself was still a virgin!
