Jen checked the clock. 11:57.
"Ugghhhhh..." Said Jenny. "So late. I'm so tired."
"Should I...sleep in the water?" She thought. "Or on the bed?"
She finally decided "on the bed."
But then there was the problem of getting herself to the bed.
"Instead of dragging myself, I could take off the costume." She thought.
She pulled herself out of the water and over to the oil. She rubbed some on her hand and rubbed that hand all up and down her back, where the seam had been. After 30 seconds of waiting, the seam appeared and she unzipped the costume. Her tail, long flowing hair, pale skin and big breasts were gone. Replaced by her long legs, brown long-ish hair, hazelnut skin and C cup breasts.
"It feels weird being a human again." Said Jenny. "It feels like I've been a mermaid for such a long time."
She hung up the costume on his hanger, still naked. She glanced down and saw the costume extensions box.
"I'll try some of those in the morning." She said and pushed the surprisingly heavy box next to her bed. "Arthur have me the day off tomorrow. I can try them on all day or the costumes themselves. Or I could hang out with Arthur. Or I could explore the grounds. I can do whatever tomorrow." She yawned.
Then she got in bed, forgetting to put on pajamas. She just climbed into her warm, comfortable bed and fell asleep instantly.
