First, a short PSA: Remember to lock your computer when you leave your desk. Robin never did. That's why one of his coworkers was able to install a very special piece of software on Robin's computer.
Willie had worried that the software would set off all sorts of alarms--What he had installed was technically malware--but it seemed the antivirus software was more concerned with infiltration of the computer or the network. This software would only infiltrate the user.
As soon as Robin got back to his computer, Willie opened the app on his phone to trigger the hypnosis process. It wasn't long until the "swap" occurred and suddenly Willie was seeing the world through Robin's eyes rather than his own.
Willie had taken possession of Robin's mind and body. Not only did he see through Robin's eyes, but he could also move his hands and when they touched something, Willie felt it just as if he himself had touched that thing.
Meanwhile, Willie's body was left in a drone-like state. Just barely awake enough to sit at his desk and appear busy enough to hopefully be left alone.
The feeling of being inside someone else's body fascinated Willie and he couldn't help but touch himself--or rather Robin--all over to experience the feel of Robin's hands on Robin's body. He let the hands slide up over the thighs and continued up towards the chest. Willie started to investigate his new body with excitement but soon noticed he started to attract attention from Robin's co-workers.
To get some private time in Robin's body, he went to the nearby restroom and he was careful to lock the door behind him. It was strange to look in the mirror and see Robin's face. His short ginger hair and pale freckled face made him very handsome. Not to mention his tall skinny figure, interrupted only by a massive bubble butt and an intriguingly large bulge.
His t-shirt came off almost instantly and Willie used Robin's own hands to explore his upper body. These hands had, of course, felt this exact sensation before. But this time Willie was on the receiving end of the nerve signals and to him, this was all new.
Continuing to undress Robin, Willie unzipped his jeans and let them drop to the floor. Underneath Robin was wearing a pair of well-fitting orange briefs. It felt a brave colour choice for a ginger, but they suited him. His bulge had started to grow.
Apparently, Willie being turned on inside Robin's body made Robin's body behave as if he was turned on. This was valuable information.
