"Since Edwin, well... Eva, wanted to play with her gender, why not share the fun with his friends?"
Eva's dad adjusted the Chronivac's setting, selecting "All Females" from the pool area. He then scrolled down to the physical appearance settings and checked "Male" under the genitals section. He then hit the "Randomize" details button, ready for a good laugh. He made sure to hit the "Adjust reality" option, except for Eva - she would be the only one aware of the changes, other than himself.
The transformation hit Isabelle first. As she was doing her laps, a slight discomfort overwhelmed her groin area and a plump package filled the space between her legs. She adjusted her swimsuit over her bulge, oblivious to the fact it wasn't there a moment before. In fact as far as she was concerned the change had appeared in her early puberty - what was first a big clitoris had grown into a quite thick little penis with large testicles.
And she remembered it was the same for every member of the team; they were affected by the same condition.
Flirty-Perci had been graced with the wildest libido of them all. Her own dick was not the largest of the group maybe, but it was certainly the one with the most stamina, always hungry for sex and drooling with pre. Isabelle's altered memory now pictured Perci, often in a state of arousal at the most inconvenient times. She shuddered a little.
As for Diane, she may be flat as a board, but puberty hit the strongest in her nether region. It's like everything she was lacking on her chest had been traded for the heavy meat she sported down there. Her cock was huge, even soft; it was a constant source of shame to her, as it would slip out of her underwear when she moved around.
It was not a problem at their swimming sessions, though. This class was special, just for girls like them. Isabelle looked up to their coach, who was herself sporting a noticeable bulge in her suit. She was the one with the idea of creating this class - a place for girls who had grown penises in their puberty to exercize without feeling guilty.
As Eva was doing her laps, she felt the Chronivac's effects washing over her. Her crotch began tingling as it rearranged itself, and something pushed out. Brushing discreetly over the area, she felt a growth which shaped itself into a penis - a second baby carrot, identical to her own as they sticked out of her groin side by side. Underneath, her balls were twice the size they used to be!
"Two dicks??" Eval gasped, losing her concentration for a second. As she looked at her friends in the nearby lanes, she could make out the outline of their bulge in the water. All of her friends had grown dicks! The Chronivac... But her father didn't know she already had a penis, and so now she had two.
In the line just next to her own, Diane seemed focused on her swimming like everything was normal. Eva's eyes widened when she saw a very large floppy member slip out of Diane's swimsuit through one of the leg openings. It fluttered underwater as she was doing her laps.
Eva's two little dicks stirred.
