For the past few minutes, something seemed off to Cassandra. Suddenly, it hit her; she was breathing comfortably underwater!
“The kiss; that mermaid; she must’ve given me the ability to breathe underwater!” she realized; but she was only half right.
Her legs quickly began to shrink away as her tailbone pushed forward. Her feet shrank as her toes thinned and elongated, a thin violet-colored webbing forming between them. Before long, they were merely a pair of pelvic fins. At the same time, the lost muscle mass from her shrinking legs filled in the tail while violet scales covered the entire mass. Finally, as if exploding from the tip of her tail, a broad caudal fin flared out.
Cassandra nearly screamed at the sight of a long violet-colored tail having sprouted from her, but she couldn’t ignore how beautiful it looked. When her last lingering fear was alleviated by the sight of a short, subtle seam in the middle of her tail, just below hip level, she continued staring at her tail, a dozen conflicting thoughts running through her mind. Her attention was only broken when someone slapped a pair of seashells over her breasts.
“Come now, even we mermaids have a little modesty.” A beautiful voice said from behind her. Cassandra turned sharply around to be met with the face of the same mermaid that had kissed her inside the cave. “For the record, I think you’re very beautiful, too. So, how do you like my little gift?”
