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.
Willie turned Robin around to check out his ass in the mirror. His underwear framed his firm cheeks perfectly. He couldn't help but clench his buttocks, so he could see the outline change in the mirror.
He tried his best to contain himself, wanting to discover Robin's body slowly and carefully, like he would a new partner. But his excitement got the better of him. With nothing to restrain him, he unwrapped Robin's clothes more like how a kid unwraps his birthday presents, and Robin's briefs soon joined his jeans down by his ankles.
Willie's exploration had made Robin's cock rock hard and this was truly an impressive sight. His best estimate put it at almost 20 cm in length. It was fairly thick too. Maybe not beer-can thick, but something like a Coke can.
While he kept the right hand busy exploring Robin's body, he used the right to start stroking the massive cock. The feeling was unique, but there was something familiar about the feeling. Almost like the first time he had his cock held by someone else or the first time he had sex.
In his excitement, it wasn't long before he brought Robin's body right up to the edge. He felt the cum building up. It felt different than what he was used to in his own body, but there was no mistaking it; Robin's nuts were ready to burst. He cupped the right hand in an effort to catch what would be coming out.
When Robin's body released its load, Willie couldn't keep him quiet even though he tried. Loud moans came from Robin's mouth as strand after strand of thick white cum shot out of his cock.
