The swimming pool

David thought about it for a moment, if it were up to him, he would just go on a rampage, fucking whoever was in front of him, who needed plans when you're as strong as a demi-god, but there were only two of them and the morning rush of the gym was about to start, dozens of people would come and use the different facilities of the gym. That's when he remembered about the water aerobics class that was about to begin and a wicked idea appeared in his mind.

"Tell me Katy, how good of a swimmer are you?" David asked Katy with a grin on his face.

"Not too shabby but I didn't bring my swimsuit." She responded returning the smile to David, immediately understanding what he was planning to do.

"We won't be needing one, come." David led the woman to the swimming pool of the gym, it was a large in-door pool where all manner of classes took place and a frequent stop by many gym goers, the perfect place to start spreading the infection. When they arrived it was still empty but in just a few minutes the instructor for the water aerobics class would show up and shortly after all the people that signed up for the class so they needed to act fast.

David and Katy both nodded at each other and dove in, the water felt a little cold on their naked, sweating bodies but they didn't mind, they swam towards the shallow area where they could stand up. David put his hands on Katy's bouncy, sexy boobs making her moan. "Ahh~ Your hands are so strong, and hot..."

Motivated by Katy's moans David started squeezing her breasts, her hard nipples poked through between his fingers. "And your tits are so big and soft." David growled; he sandwiched his rock-hard cock between Katy's wet tits. "This feels so fucking good!" He couldn't stop moving his hips as he fucked her tits. He thrusted his cock deeper and deeper into her cleavage as if he were pushing into her pussy. He then felt a surge of pleasure coming from his tip and heard a slurping sound. Katty wrapped her tongue around his cock and she was taking it all the way down her throat.

"Fuck! I'm going to...!" David groans and as much as he wanted to fed Katy his infected seed it was needed somewhere else. He pulled back and Katty quickly repositions herself to stroke his throbbing manhood vigorously. David let out a beastly growl as his cock erupted a substantial load of foul cum inside the pool. His sex fluids dispersed in the water contaminating it.

"You think that's enough? I don't mind doing it again but is your turn now." Katy said rubbing her pussy lips as she gestured David with her other hand to come closer.
