One the creature finished loading brainwashing serum to Seung Min’s brain, he ordered his obedient fathership to get on his knees and bring his face close to his crotch. The fathership began serving his new owner as it was programmed on the hunk’s head.
As the alien was satisfied on his new fathership’s functions, the last part of his transformation could take place. This part required to change not only Seung Min’s brain internal structure, it required some physical changes to be done here.
The helmet did the physical change by drilling through his brains, leaving a gap between the two hemispheres. As it finished doing that, the alien was ready to load the finishing serum into his servant’s cerebrum. It placed its dick into the warm, juicy now yellow matter and loaded the final seed into it. Leaving it drenched and fully transformed into his new cumdump.
