Kevin frantically looked around at school and found Kendra walking and talking with some of her girl friends.
"Hey Kendra," called out Kevin. Kendra tried to ignore him at first. He caught up and gently grabbed her arm. "I need to talk to you. It's about that...uh...marine biology project I was helping you with."
"I'll see you girls later" said Kendra and she reluctantly stopped to talk to Kevin.
"I thought I told you..." she began. Kevin showed her his hand. There was now webbing between the fingers almost to the tips. He put the hand back in his pocket so that nobody else would notice.
Kendra's heart rate quickened. "Have you had any other changes?"
"Not that I can show you with my pants on."
"If you take a shower you should return to normal afterwards." Kevin gave her a curious, hopefully look. "Even if it's a shower by yourself." His shoulders sagged.
"Okay. Thanks." Kevin turned and headed for the gym.
Kendra turned to head for her first class, but something didn't feel right. She was feeling warm. She had taken a shower that morning and transformed so that shouldn't be a problem like it had been yesterday. She realized she was feeling aroused at the thought of Kevin as a frog boy. She shook her head. Yesterday was a one time thing. She brushed some hair out of her face and stopped suddenly. She looked at her hand. It had a faint green tinge and there was webbing growing between her fingers. But she had transformed this morning! Was it because Kevin had touched her and was in the process of transforming? Was it because she was getting aroused?
She turned around and hurried in the same direction Kevin had gone.

For the second time in as many mornings, Kevin hurriedly undressed in the boy's locker room and stepped into a shower stall. His toes weren't webbed like his fingers, but the skin around his crotch was turning green. The transformation seemed to be spreading out from his dick. He turned on the shower and stood under the water. He didn't hear the locker room door open.
Kendra recognized Kevin's backpack and the pile of his clothes. At least she had the time to undress properly, unlike yesterday. Her fingers were about half webbed so far. Green splotches were forming all over her body. Her crotch, butt, and breasts were completely green. Her nipples, a darker shade of green, were hard. Naked, she stepped into what she realized was the same shower stall as yesterday.
Kevin's eyes went wide: Kendra had joined him after all and seemed half transformed. Kendra's eyes went wide as well at the sight of Kevin's big green dick. She suddenly went from aroused to having never wanted a dick in her as badly as she wanted that dick in her. She licked her lips.
"Changed your mind?" asked Kevin.
"I guess it's your lucky day" replied Kendra. "Again."
