He stops by his gym

On the way home Jon first planned to head home directly but another thought pushed into his mind. His body felt as if it had changed in that weird night at the forest but he wasn't sure about that. He turned into a parking garage at the city center near his workplace and a few minutes later he stepped into the gym, where he was training from time to time after work. The receptionist smiled as he stepped out of the elevator and a few minutes later he had changed into some training clothes. When he stepped into the main room, he noticed that it wasn't that crowded as he was used to in the evenings during workweek.

He went over to some training devices and set them to his usual settings, quickly realizing that they were way too weak for him. He had to increase settings significantly before he started to sweat.

"Wow," he then heard a female voice say. "Wish I could run so fast."

He looked up and spotted a young woman, who quickly came over to him, watching his settings on the treadmill. "Hi, I'm Jon," he said while running the speed easily.

"Hi," she said and he noticed how she seemed to start breathing quicker. "This is impressive."

"Thanks," he responded and kept watching her. He could see her nipples get hard through the fabric of her sport bra. "Everything alright?" he asked as she leaned a bit over, almost moaning. She seemed to behave strange, even with him completely clothed.

"Uh ... yes ... maybe ...," she said and a moment later she pushed her hands in her pants. "I'm just ... so horny," she mumbled and bit on her lips while she clearly was playing with her pussy. He stopped running and before he could react, she was on her knees and pulled down his pants. Seeing his cock caused the familiar reaction. Her body didn't changed but her eyes became way more slutty and she licked her lips. Then she started to suck him off.

Soon he had come in her mouth and bend the young lady over one of the benches, fucking her passionated from behind. Although some of his thoughts circled around her behavior earlier. Something seemed to made her horny even without seeing his cock. Was his theory about the changes flawed in some way. He kept pounding here and at some point a drip of sweat dripped from his face onto her back. It instantly clicked in his head. He was sweating when she started to behave like this. Maybe that was another ability, was his sweat making women horny?

He fucked her for another ten minutes and finally came over her trained ass, before pulling up his pants. He was just walking towards the exit as he could her talk with some other guys in the room, asking them if they could help her with another load of proteins for her training. When he looked over his shoulder the three guys had her bend over already again and started to fuck her. Jon smiled as the girl seemed to enjoy the porn movie reality unfolding around her.
