A hybrid between a YCH and a commission made by  azeriunleashed as the two first panels are part of a YCH, but everything that comes after was part of a commission. I am very excited about this piece as I am a huge fan of both Azeri's symbionte and Topazknight's Mephiphages and this combines some of my favourite kinks into an awesome package.

Mini story:
Ronin, that kinky dog-deer-horse boy, had accepted to help out inseminating this space-creature. They feed themselves with semen, but there are records of one of this wigglies actually getting inseminated and releasing eggs, so scientists have long tried to find the right specimen that can help the creature reproduce: many tried but failed, the creature would just dethatch after feeding and leave.
This time something peculiar happened, the creature's rear opened up like a flower and attached to Ronin's face, pushing down a couple dozen eggs in his digestive tract, but it was not all: once they were done they let go of both Ronin's manhood and his face and proceeded to force their way into Ronin's mouth, causing Ronin to suddenly get stimulated and ejaculating uncontrollably.
Once he had expelled all of the eggs the scientists had no clue over why the creature fed itself to Ronin and assumed it part of their mysterious life cycle, so they just let him go... little did they know the creature was still alive inside Ronin and was now looking for a new host~
