Laura slowly swam along the shadows, breathing slowly from the small SCUBA tank she wore, her hands at her sides. Her strong shapely body was encased in a black long sleeve leotard and full black tights that disappeared into a pair of simple black rubber fins. One of her sexy legs had a knife strapped to the calf. A black rubber mask and lycra gloves completed her outfit. She knelt on the bottom and looked around warily, her black hair floating around. She reached down to fondle her breasts and masturbate when some underwater lights came on ahead of her. She closed the snap crotch hastily as she stared curiously.

Suddenly, someone jumped into the lit area. When the bubbles cleared, Laura could see that it was another diver. A very sexy looking voluptuous blond "frogwoman". She wore the same outfit Laura did, only in dark blue. She looked around until she saw Laura. Laura swam toward her slowly, a curious look in her eyes. It was Jennifer.

At that moment, Jennifer recognized her, too and reached down her sexy leg for her knife, an angry look in her eyes. Laura pulled her knife out and swam toward Jennifer, pointing it at her. The two women caught each other's knife hands and began to wrestle underwater, bubbles pulsing from their regulators. They struggled in a flurry of black and blue lycra, their fins kicking as they rolled over each other in three dimensional combat. Laura felt Jennifer start to weaken and doubled her effort. She managed to push Jennifer to the bottom and roll her on her side. Jennifer struggled to get free, a look of terror on her face. Laura trapped both of Jennifer's hands with her free hand. She freed her knife hand as Jennifer shook her head and whimpered into her regulator.

Laura was really enjoying this. She put her knife down and fondled and squeezed Jennifer's breasts, then she knelt behind Jennifer while still holding her hands, reached down, and removed one of Jennifer's fins. She twisted Jennifer's tights covered toes until she heard her squeal. Laura ran her hand up Jennifer's leg and began to rub her clit through the leotard and tights. She felt Jennifer tense up, her breathing short and choppy, then relax. Laura felt warm fluid on her hand.

Laura reached for her knife and held it menacingly in front of Jennifer. Then she stabbed Jennifer below her breasts. Jennifer curled up around Laura's knife, her eyes clenched in her mask. Laura stabbed again, moving the knife around, then released her.

Jennifer swam backwards, her one fin kicking feebly. She stopped and sank back, her regulator falling out of her mouth and a small stream of bubbles escaping. Laura pulled herself over Jennifer. She removed Jennifer's mask and straddled her face, her hips gyrating with heat. Moments later, laura arched her back and came, a stream of bubbles gushing from her mouth. She put her knife away and nonchalantly swam back the way she had come, water swirling between her breasts and around her hard nipples.

On the surface, she stood in shallow water and pulled her mask up on her forehead. She heard bubbles behind her and turned around.

"That was great! I can't believe I could cum like that underwater."

"I almost came when I stabbed you. What an act. How erotic. I'll 'die' next time"

"These rubber knives are great"

"You can do some neat things with handles, too," Laura whispered as she kissed Jennifer. She pulled her mask back on and grabbed her regulator.

"I hope the camera is still recording." said Jennifer as she followed her lycra covered lover underwater.
