Under the surface, she holds her breath, the water pressing against her, filling her ears, muffling the world above. She kicks her legs, propelling herself downwards, her body fully submerged. She feels the water's pressure against her skin, her pussy throbbing with need. She reaches down, her fingers finding her clit, rubbing it in tight, quick circles. Her body tenses, her lungs burning for air, and then, with a rush of bubbles, she comes, her orgasm pulsing through her body as she breaks the surface, gasping for air.
