Once they emptied Ian’s mind, the boss of the organization twisted the machine’s original brain sucking functions to begin to fill it but not with the spy’s original content, if not of a serum that made the subject’s brain completely docile towards their new owner.
The machine needed a helmet so that the content doesn’t fall outside from Ian’s brain. While inserted into Ian’s opened head, the machine began pumping its contents into the former spy’s brain, drenching it completely reaching all of the brain’s regions.
Ian’s blank face began to react softly into the serum’s insertion into his brain, having his pupils shiver as the load pumps through his brain lobes.
Ian moaned softly as the machine continued flooding his cerebrum with the mysterious relaxing content as it finished loading all of it.
The machine stopped and Ian’s blank stare remained but his open mouth began smirking as the serum took over his brain.
The boss began enjoying his new addition to his crew by measuring Ian’s biceps as the spy mindlessly flexes it to obeys him to every command. The boss softly mentions his excitement of adding the spy into his team as the spy nods and agrees with him with a "yes, boss".
As the process finished the boss watched the liquid surrounded the spy’s head and brain as he looks his toy’s skull to reinsert it and enjoy him as much as he wants.
