Syzoth couldn't explain it.
His son just vanished without a word or an explanation.
Of course he was worried and decided to find out what the hell actually happened.
And one day, the body was found.
Someone put his mutilated corpse inside a bag and threw it out into the nearest river.
It seemed like his boy got into a gang or something, and then got killed there.
The ones responsible were caught and condemned for a life imprisonment, but that still didn't bring him his boy back.
Syzoth then didn't care about his life anymore.
His life then just went even worse.
He became an alcoholic, but funnily without paying for any alcohol. He did it all himself.
And then, after a few more years of pain he was killed by some thief who broke into his house.
But to Syzoth's surprise, his life didn't end then. A powerful being chose him as his champion for some reason, gave him a new body, a new life, and a new purpose.
And that was the sole reason he put up with most of the shit his so called "teammates" pulled. Not all of them were bad. But sadly most of the actual good ones died in the first few years.
But even after all the time, some of his old habits didn't seem to die.
After taking a sip of the devils potion, his innate ability to easily understand the potion made it possible for him to make an antidote to the serum.
Syzoth was also lucky that the liquid itself was relatively low grade.
If it were any higher tier, Syzoth may have been nothing more than a mindless servant to the devil.
But his love for remaking and perfecting potions carried on, and so he worked on the new potion as a side project.
After countless attempts he was finally able to find out the necessary ingredients needed for the potion.
Basically if you were ti spray a "marangla", a rare demonic plant with the urine of a succubus, the plant wound grow fruits, whose juice would be a necessary component for the potion.
The higher rank and more powerful the succubus you got the urine from, the better the outcome.
How did Syzoth got the urine?
That's a story for another time.
Whatever the case, Syzoth wasn't sure at first what he exactly created, and so he tested it on a few of his lab rats.
All of them showed the same pattern.
The rate in which their hormones increased exponentially, with it their wish for reproduction.
If their need weren't satisfied, they would die in a matter of seconds.
Those that did survive however seemed to have an intimate relationship with their partners.
They would protect them at any cost, take care of them, bring them food, scratch them.
They also didn't like when other rats came near to their mates.
That was however only if the rat that drank the serum was a male.
If it were a female however, the effects were similar to those of the male species, but the female seemed to be somehow infecting other females into being more lovable towards the male rate the female rat mated with.
No form of jealousy seemed to exist.
However Syzoth quickly found out that after a single week, all female rats refused to reproduce with other male rats, all but the mate of the female rate that drank the serum.
They would ignore all advances of the male rats, and even when they tried to get the deed done forcefully, the female rat would give a loud squeak, in which all other infected female rats ran at the male one and tore him apart.
And when Syzoth removed the one male rat that somehow got himself a harem, the females still refused to open up towards the other males.
Syzoth then decided he had enough, and had made sure to not do it again.
That happened again when he did it in a tank with only female rats. All other rats seemed to try to get impregnated by the other female rat after a mere week, even when they should know that it wasn't possible.
And Syzoth did do the same when he gave in a tank full of male rats one to sip of the serum.
The effects were similar to earlier experiments.
Not having a female rat to mate with, it then just took thr nearest rat and mated with it.
Then, even when thar rat tried to get away from it's rapist, the other rat always managed to find it and tried to continue the deed. That, and it would aggressively attack anyone who approached them.
Syzoth had to remove him.
His snake had a nice snack.
But a scientist needs other test subjects, and again, the same result.
No matter if it were a hog, a lizard, a snake, a bird or even a fish, the results were the same.
If the consumed didn't mate with somebody they would always die in a few moments later.
Syzoth, being shocked at what he created, made sure that it wouldn't get used accidentally again.
He did however decide to keep, just in case it could be used.
But now, the tiefling drank all of it, and before she could get to him, he quickly slammed the door.
The tiefling pursuit to punch the door again and again, but somehow it didn't seem to bulge.
Only a few moments would the dood show some cracks.
Syzoth knew that it was only a matter of time before the door would break, and the deviled one rushed to mate with the single entity that could be possibly mated.
Syzoth himself.
Syzoth also knew he couldn't run away.
If he were to do that, than Luciana were to surely die, and being a princess if tieflings, knew that her death alone could potentially start another major conflict.
Something that Syzoth really didn't wish to deal with.
So he took his remaining time to make another potion.
A potion of stamina recovery.
Syzoth, knowing a little bit of demonic culture, knew that some deviled one, those that had royal blood especially, possessed a unique gift that the female would suck out the litteral life force of their partners if the male ones were to suddenly tire.
Syzoth didn't wish to experience it again, made sure to create and drink as many endurance and stamina recovery potions as he could.
He knew that he would need all of it.
Just as he was about to drink his tenth potion, the door broke, and a blue tiefling ran op at him with a uncontrollable lustful face and glowing hearts in her eyes.
