I knew it…

That spell was far too dangerous. What was I thinking? Summoning my future self to possess my body. So what if I won the battle against the Demon? So what if he saved my life? Looking at the ashamed and red faces of my wives who were thinking of cheating on me made my heart wince.

In truth, I had never once worried about the four girls falling out of love with me and leaving to find someone else. After all, I knew the full extent of their emotions. Irina was crazy over me, so much so that she would steal my fingernails and strands of hair. Lilith was obsessed and would do anything to spend one more second with me. Be it in the bedroom or in the lab.

Ysabelle was willing to put her life on the line to save me, and her love was equally as heavy as the rest. And finally, Rosa would never even think of cheating and would trap me in a prison of her making.

Those four girls would never cheat on me, and no man on the planet could steal their hearts.

But there was one other person that their hearts would move for… Future me.

Since I was slumbering within my soul, I didn't know the full extent of his powers or charm. And right now, I hardly even cared. I dragged the four girls away from the wedding venue and straight into the bridal room.

"J-Jin, what are you doing?" Lilith gulped and watched my every move hesitantly. "We can't just leave the guests unattended, right? I'm sure they're still in shock after that whole affair."

"Y-yeah! Brother, we should return and finish the ceremony. Technically, we aren't married yet!" Irina followed up with shifty eyes.

"J-Jin… I-I'm sorry! I-I-It won't happen again!" Ysabelle, feeling the most guilty of the four, attempted to apologise and make up for her cheating heart.

"..."

As for Rosa… Well, she's given up. Closing her eyes, she laid down on the silken sheets and with eyes like a dead fish, she spread her legs.

Ah… The plan was ruined… I wanted to make our wedding night special. I wanted to give them the grandest wedding in the history of mankind. I wanted to make this night a night to remember. I wanted to provide them with the best wedding and, immediately after that, give them the best sexual experience we would ever have.

This entire bridal room was designed for that purpose.

A bed big enough to fit a dozen humans was decorated with an assortment of beautiful flowers and scented candles. Numerous sex toys were spread throughout the room, even a chamber with special 'tools' that would enthral Rosa. Romantic music played in the backdrop as vitality pills were prepared for the five of us.

I was planning on making this a night that we would all remember for the rest of our lives, yet… It was all ruined!

All because of that stupid spell.

"No, I was a fool. I shouldn't have played with time."

"B-But, you saved us, Jin!" Lilith exclaimed with joy in her heart. As if trying to appease me, the girl approached my side and gently drew a circle on my chest. "If you didn't summon yourself from the future, we would have been doomed. And besides, future you told me to tell you this!"

"I don't want to know what that thief said," I scoffed and grabbed Lilith's shoulders. Flying her up into the air, I pinned her down onto the bed and stole her lips.

My tongue ravaged the stunned blonde beauty, and my hands moved wildly over her lovely wedding dress. I didn't care about how expensive her goddamned clothes were. Treating her rougher than I'd ever done, I rubbed her chest and broke the diamonds ingrained in the cloth. Two of my fingers grabbed her cleavage, and with a single yank, I pulled down her ivory dress, revealing the two perky peaches all men desired.

I released my grasp on her lips and looked down at those scrumptious breasts. The desire to conquer and plant my seed into the woman underneath me almost immediately filled my veins. My manhood was already starting to come alive, and my chest enlarged from my heated breaths.

"W-Wait, j-just wait a minute, Jin!"

Once again, Lilith made a plea for innocence. No, she was trying to distract my mind away from her previous infidel thoughts.

"D-Don't you want to know how the Outer Demon was defeated? Don't you want to know the truth behind your power?"

"The truth behind my power?"

"T-That's right! W-We can work that out together! You can become even stronger than you are now! If you can't remember, we can share our memories! In the future, you will become so strong that no one can stand in your way! Isn't that your goal? To become stronger?"

Lilith's proposal did sound tempting.

While I had summoned future me, I wasn't in control of my body. Therefore, I didn't know what occurred during the time I blacked out. However, my consciousness was immediately awoken when future me intended to take my wedding night away from me and steal the girls I loved.

If I reviewed their memories, I could figure out how to escape this bottleneck I was under and ascend into a higher tier of power.

But that didn't matter to me now.

"I could care less about that," I snidely snapped.

Why did I want to become stronger? Wasn't it because of my four beautiful wives? I wanted to become strong enough to be worthy of them. I wanted to become strong enough to ward off potential thieves who might steal their hearts. And… I wanted to become so strong that no one could ever pose a threat to them.

That was why I was so reluctant to use that spell.

I feared I would lose my wives forever if I summoned future me. And my fears weren't unfounded. If I were just a few seconds late, perhaps…

I unmounted Lilith and looked around at the other three girls. Irina and Ysabelle were still standing behind me, unsure of what to do or feel. Therefore, I helped them.

Pulling them onto the bed, I abruptly pinned the four down, standing over them like a shepherd watching his sheep. In one whole movement, I tore my tuxedo and pants, leaving me with nothing but a bulging underwear. But even that was too much, as my manhood had slowly gotten big enough to erupt through that single piece of cloth.

The four of them looked at me shyly as if they knew what was to come.

In the past, it was hard to get all four of them onto my bed at the same time. They all wished to monopolise me, and the thought of sharing their lover willingly in bed was apprehensive to them.

But this time, I was the one who wanted to monopolise them.

"You four were naughty girls… To think you would even consider cheating on your husband on your wedding night."

"T-Technically, that man is also you, so…"

"Oh? So your heart has been captured by him?"

"N-No, o-of course not!"

Lilith quickly looked at her fellow sister wives, praying that none of them would throw her a saving line. Alas, none of them talked, and they desperately avoided eye contact. I could feel Lilith's heart shatter as she lost all hope.

"It seems like I must teach you all how to be faithful again."

I pulled down the final piece of cloth holding my manhood back in check. Channelling magic from my life ring, I increased my vitality and enhanced my essence a thousandfold. With that magic in play, I had essentially a gun with infinite bullets locked and loaded.

The meaty rod flung out with a vengeance and stood just as erect as the tallest mountain on Earth. Blood pumped into the shaft as it grew bigger by the second. Turning as hard as diamonds themselves, my dragon roared angrily, and the little kittens on the bed meekly stared at it.

Flicking my fingers, I sent magic down their bodies, abruptly disrobing them from the neck down. Their intricate white bodies were now ready for my eyes to feast on. Irina's immaculate white thighs, Lilith's mesmerising breasts, Ysabelle's perfect hourglass figure and Rosa's adorable bush…

They were all mine!

I was not going to let another man steal them!

I need to ingrain it into their souls so that they will never have such infidel thoughts ever again.

"Girls, you better be prepared. Tonight is going to be the longest night of your lives."
