How things started

Entering the world, Dexter was put in a normal village with no real danger besides the fields and forests, which hold a few slimes. Like a naive child, Dexter ran into the fields of slimes, finding out that one of his cheat abilities had become his downfall, as these slimes had used the transformative properties of Dexter's powers to become slime girls. Now, as slime girls, these monsters ravaged Dexter, keeping him hidden in the fields for days as they milked and milked and milked him of his cum. When they were done with him, this sexual experience and deep affection brought about by his other power caused most of these slime girls to evolve into slime mothers. As a thanks, these sexy milf slimes gathered their DNA together, creating a basic newborn slime using the properties of Dexter's powers while he lay limp on the ground, creating a one-of-a-kind existence that was destined to grow endlessly and evolve into something beyond the realm of possibilities for slimes, but also something feminine and humanoid, since this new life was piggybacking off his powers like them.

As for the slime mothers, their minds had expanded to a point that they realised simply staying in these lands would invite disaster, so they got all the other slimes and left for new lands, leaving Dexter and his little slime, watching as it already wriggled onto his dick and began sucking.
