Reincarnated as a step-dad in a fantasy world

Jack opened his eyes and found himself in a space where everything was blank, as if he had entered a realm beyond reality. He sat up, contemplating the situation, and wondered aloud, "Am I truly dead?" A voice responded from behind him, confirming his suspicion, "Yes, you are indeed dead."

Startled, Jack turned around to see a man in his thirties standing there. The sight of him left Jack speechless, for the man was the epitome of beauty and grace. His long, silver hair flowed elegantly, framing his handsome face, while his gray eyes seemed to hold the secrets of the universe. His flawless, unblemished skin exuded an otherworldly radiance, and his immaculate white attire only enhanced his angelic appearance.

As Jack's gaze lingered, the man teasingly remarked, "Have you finished admiring me?" Feeling embarrassed, Jack quickly apologized, "I'm sorry."

With a playful smile, the man introduced himself, "I am Alexandre Eswald, you can call me alex. The reason why we both find ourselves in this blank space is due to my power called 'soul linkage.' You see, like you, I died, betrayed by my best friend."

Curiosity piqued, Jack inquired, "Why did your friend betray you?"

Alex's expression darkened momentarily before he answered, "There is many reasons and one them is that he discovered that I was fucking his wife and that I was the father of her four daughters-"

"Huh," Jack was taken aback, and he couldn't help but ask, "If you were fucking his wife, wouldn't that mean you betrayed him first ?"

Alex's eyes narrowed with lingering pain as he countered, "I may have fucked his wife, but does that truly warrant death?"

'yes, you do deserve death' though jack thought that, he didn't say it out loud.

Meanwhile Alex continued by saying "the other reason is that I had something precious that he wanted"

Curious jack asked "what is that "something" ?"

Alex replied " you will know later".

As the blank space seemed to envelop them in silence, alex revealed an astonishing proposal.He explained that through his power, the "soul linkage," Jack's soul could be reincarnated into alex's body. This revelation left Jack bewildered and anxious.

Seeking clarity, he asked, "What do you mean by that?"

Observing Jack's agitation, alex reassured him, "Through my power, I can arrange for your soul to inhabit my body, more or less. But for that to happen, you must promise me two things."

"Before that, what do you mean by 'more or less' " questioned jack.

"To tell you the truth, I only have an inkling of what might happen," honestly replied Alex.

"Hmm" 

Seeing jack pondering wether he should take his offer or not, Alex said to him.

"I might not know with certainty what might happen, but I can at least promise that nothing will happen to your soul, or mine for the matter, so, you don't need to worry."

"Plus, you don't really have anything to lose, you are already dead, we, are already dead" chuckled Alex.

Alex's last remark seemed to have convinced Jack, so he curiously inquired, "What are these conditions of yours?"

Raising a finger, alex enunciated his first request, "Firstly, you must seek vengeance on the man who killed me, and you also need to save his wife and daughters"

Jack nodded, understanding the task. He replied solemnly, "I promise to fulfill your first condition." he then continued by asking alex "what is the second condition ?"

Alex grinned at jack and said to him " fuck them all" 

"what ?" dumbstruck by that last statement jack asked "fuck them all, what do you mean by that ? and who should I fuck ? "

Alex responded calmly by saying " you see I'm surrounded by beautiful women both young and mature, and that was at death door that I regretted not fucking them, of course, this is not the only reason but it is the only I can talk about right now", he smiled at jack and continued "as for whom to fuck, you will decide by yourself, you can fuck them all or just some of them, after the merging of memories you will know more about me and those around me"

Jack still confused asked "I understood what you said earlier, but I still can't see the need to fuck women, why would you want me to fuck women, and why is having sex with those around you, your f*cking last will ?"

Alex sighed and replied calmly, 'You will know all those reasons later. Also, it's not really my last will; you will understand later what I mean. I can't get into details right now as we don't have much time. All you need to know now is that fucking with women would greatly help you in your journey. Believe me."

Just when he finished speaking Alex seemed to remember something and said "Ah, you also need to take care of my wife and children".

"You have a wife ?"

"Ah, yes, I didn't tell you, but I'm not as young as I look. I'm actually sixty this year. And yes, I have a wife, and we have four children. Well, the first three are not my biological daughters; only the last one is my blood daughter. But since I raised all of them from their childhood, I consider them all as my own," explained Alex.

"As I was mentioning, you need to have sex with as much women as possible. That's the second promise you need to make."

Jack contemplated on the conditions conditions and asked " why won't your soul return to your body ? if you can use your power to send my soul in your body why can't you do the same for yourself and why did you chose me ?"

"I already tried but it's seems that my soul can't return in my corpse, from my understanding it's because I already died in this world, apparently the world won't allow that the soul of someone dead to return"

Jack couldn't understand and asked " how is it different with me, I'm also dead"

Alex smiled and said " yes you died, but not in my world, you and I are from different world which make me assume that my world might permit that your soul take over my body" 

Jack was taken aback by the revelation that there were other worlds beyond Earth, and that he and Alex hailed from different realms. He tried to process this newfound knowledge while attempting to calm his shock. 

Alex, noticing Jack's stunned expression, gave him a few moments to collect himself.

"What happens if your world doesn't allow me to take over your body" questioned Jack.

"Well, in this case I guess both of us will ascend to heaven...or hell. In either case it's mean that it's truly the end of the road for us" answered Alex, but then added:

"I don't know about you, but I'm surely not ready to kick the bucket"

"Wait, you said earlier that those conditions are not your last will and now you are saying that you don't want to kick the bucket, so, I'm wondering, what will happen to your soul once I take over your body"

"I will explain it once you decide to accept my offer. So, what will it be? Are you on board or not?"

Jack paused briefly, thinking before responding with unwavering determination, "Yes, I accept."
