Looking over, Ty spotted the girls' parents lounging and chatting with each other. As the girls were young, so too were their parents. Ty wasn't a great judge of people's ages, but assumed they were somewhere in their late 20s to early 30s. All the parents (three dads and three moms) were keeping an eye on their daughters, but also seemed more interested in the drinks, and conversations they were having. Each set of parents were of varying body shape. One pair was fit and in shape, one was the classic dad and mom bod, and the third was overweight and would be considered chubby.
A mischievous idea hatched itself in Ty's head as he watched the little girls play, and then back over at the parents.
"Switching things around should be fun!"
Ty concentrated on shifting the genitals of the dads onto their daughters. He turned his attention back over to the girls to watch the change. Two of the girls were in one-piece suits but one was in a simple kid-style bikini. The transformation started slow. Each of the girls' in alternating order occasionally began to rub in between their legs. It would be hard for anyone else to notice yet, but to Ty, who was expecting the change, the smallest of bulges had started to grow in the polyester bottoms.
As the change began to enhance, one of the girl's made a grunting sound, almost like a cough. Ty saw that her change was further along, and could make out the outline of a thick flaccid penis trying to find the space to grow in the tight bathing suit. The girl noticed and let out a high pitch scream, "Moooooommy!" before running back to her parents. The other girls soon followed suit. The taller of the three girls' penis had started to poke out the side of her one piece suit with two large balls still trapped. Dark hair was growing around the obscene bulge. Meanwhile, the girl in the bikini style bathing suit could see more of what was happening. Her new penis had pushed out the band of the suit, with the base of her dick poking wide. Her hairy scrotum was still in the bottom.
Ty cackled with laughter watching the girls run over to their parents, and seeing the parents reaction of pure shock and fear as to what was happening.
Almost at the same time, each of the dads were finding that they had an excess of fabric from the bathing suits in between their legs.
