"Hey Jen," Mark said.
"Hi Mark," Jen replied. Her heart was beating fast. The bell rang.
"We should get to class," Mark said. They walked to class, holding hands.
When they got to class, they both had a strange feeling in their butt's, as if their buttcrack's had gone numb. The feeling spread to their groins. This they both noticed.
"Can I go to the bathroom?!" they said simultaneously. The teacher nodded and they both left. They started talking in the hall.
"Kinda wierd how we asked at the same time," Jen said.
"Yeah. I've got a wierd feeling down low," Mark said.
"You too?" Jen asked, "We better check this out together." She half said that because she wanted to see him 'grow'. They went into the bathroom togeher and stripped from the waist down.
"AHHHHHH!!" They both screamed. The were looking at each other's light blue scale covered butt's in the mirror. Jen's leg flesh fused all the way down like a zipper. She tried to take a step and fell over. Her feet flattened out and spread out as the crease between her legs filled in. Mark just stared. He tried to run away fell over because his leges were fusing together too. Both their tail's grew 15 feet long and fused together at the place where there knees should be. Jen's arms got sucked back into her shoulder's and a dolphin's dorsal fin grew from her back, bursting through her shirt an breaking her bra strap. Her breasts grew to DD cup, tearing the rest of her top to shreds. Her top and bra fell off. A dolphin's dorsal fin grew from Mark's back through his shirt. Scales covered them from head from head to toe. Jen's hair grew to 6 feet long. As the transformation ended, Jen passesd out from shock.
