His Cock?

Sam went to get up off the couch, keycard in hand, only to feel a surprising sensation between his legs. His cock, which had just been drained better and more completely than it ever had, was rising. He was still horny, too. The porn on the screen was still going, and he was still drawn to it as if he hadn't just blown a giant fucking load.

He slumped back down to the half-lying position he had just held and just sort of marveled at himself. His fuckstick was standing at full attention again, without any of that achiness he felt when he tried to jerk off two times in rapid succession. He was full-on ready to go. What's more, he was fairly positive his cock was bigger now? At least an inch longer, bringing him to a full foot, and slightly wider. His cockhead also seemed more bulbous and shapely, almost as if he'd received a cologen injection like women get in their lips or ass.

"What the fuck did that robot do to my dick?" Sam murmured to himself.

He knew he wasn't supposed to, but he had to touch it. Take it for a test drive. He licked his hand and started stroking himself slowly up and down. It seemed to feel even better than ever: Was he still sensitive after the extended period of pressure pushed on his manhood, or was this from the robot too? He reached down to his balls. They seemed bigger, somehow denser, and were hanging low as cum built up for his next fuck.

Now Sam had two goals. To get out of the maze, and to figure out what happened here.
