Your parents, having adopted the four of them from a research facility, created a unique family dynamic. Despite the differences in your backgrounds and personalities, there's a deep bond that connects all of you. This summer, your parents rented out an entire cruise ship for a much-needed family vacation. You’d all spent the night aboard, and as the morning sun streamed through the windows, everyone gathered for breakfast.

As you finished eating and began to relax, you heard your stepsisters call to you from the top deck.

“Hey, bro, you coming to join us in the hot tub?” Eve’s voice carried over, laced with playful energy.

Sighing but knowing you’d be hard-pressed to avoid them for long, you made your way up to the top floor. As you approached the deck, you saw the group already settled in the hot tub, the warm steam rising around them. Each of your stepsisters was in their own unique form, shifting in size as they relaxed in the water. Eve was perched on the edge, her fiery aura barely contained. Mia was sprawled out, small but with an air of stubborn determination even as she leaned back against the tub. Ivy, as always, was serene and calm, watching the gentle waves outside. And Ella, with her usual welcoming smile, waved you over.

"Come on, the water’s great!" Ella called.
