Amelia dismounted from Vicky and flopped down next to her, leaning against the wall of the shower, fluid dripping out of her. She couldn't believe she'd just lost her virginity to an intersex frog girl from her swim team.
"I guess I can trust you to keep my secret," said Vicky.
"Of course, but I hope this isn't a one-time thing," replied Amelia.
The two exchanged a knowing grin that showed both of them agreed.
"We should get cleaned up. At least we're already in a shower."
Vicky helped Amelia up and turned on the water. Getting clean soon turned dirty as they sensually washed each other. Soon Vicky had another erection.
"I'm starting to understand why teenage boys act the way they do..." muttered Vicky.
Without any further prompting, Amelia squatted down in front of Vicky like a frog then began fellatio. It didn't take long for Vicky to blow her load again, coating Amelia's tongue and throat in her froggy fluids.
The two finally finished washing, dried off, and got dressed. Vicky's feet were uncomfortable in her shoes, to say nothing of the uncomfortable tightness in her pants.

As she lay in bed that night, Amelia couldn't stop thinking about Vicky. As she fondled her breasts, Amelia couldn't help but think they were bigger and more sensitive. Her hands felt so good on them; they reminded her of Vicky's webbed hands... Amelia suddenly jumped out of bed and went her bathroom. Turning on the lights, Amelia saw she hadn't been imagining things. Thin webbing had formed between her fingers. Her breasts were a cup size larger, and the areolas had turned dark green. Her mouth was feeling strange as well. Amelia opened wide and stuck out her tongue. The what extended from her mouth was no longer entirely human.

Amelia's phone rang the next day, Saturday; it was Vicky.
"I've got a surprise for you," she said.
"That makes two of us," replied Amelia.
"There's a big party tonight," said Vicky. "I want to bring you as my guest."
"Oh..." replied Amelia. "I was hoping we could spend some time together...privately."
"I'm sure we'll have time for that as well. What's your surprise?"
"I'll show you tonight."

Vicky picked up Amelia in her car. Hopping into the passenger see, Amelia quickly looked around to ensure nobody was watching. Then reached over and pulled Vicky into a kiss. Vicky was briefly surprised by Amelia's forwardness, then even more surprised by her new tongue. "Wow..." was all she could manage when she came up for air then before going back to kissing. After several minutes of that, both girls were panting.
"Sure you don't want to skip the party?" asked Amelia. She held up her webbed hands to accentuate the point.
"Let's still go, but if it's lame we'll make our own fun."
It was a short drive to the party. Lots of people were clearly there. Music could be heard from the back yard.
As they walked toward the front door, something crossed Amelia's mind. "Is this party mostly guys, mostly girls, or a fairly even mix?"
Vicky shrugged. "I have no idea. Why?"
"If you've passed your transformation on to me, you probably passed along the entire thing. Remember what I said about frogs and Jurassic Park? I might end up with a penis too, or you might end up getting your vagina back."
"Oh." Vicky shrugged. "We'll find out shortly." Her dick twitched with anticipation.
