Percy, a young man with a peculiar talent for hypnotism, decided to hypnotize his mother and his cousin's girlfriend one sunny afternoon. With a slight flick of his wrist, he sent them both into a trance, their eyes swirling mysteriously. He suggested that they were going to go swimming, and so they did, both of them walking towards the nearby lake with an odd, dreamlike grace.

As they swam in the clear waters, something peculiar began to happen. The lake began to glow with a soft light, and strange, colorful fishes started to appear around them. They swam around with the fishes, seemingly a part of their world now.

Suddenly, a giant turtle appeared, swimming slowly towards them. Its shell glowed with the same light as the lake, and it seemed to radiate a sense of calm and wisdom. Percy's mother and the girlfriend seemed to understand the turtle, nodding at its silent words.

The turtle led them deeper into the lake, revealing a hidden world filled with magical creatures. There were mermaids with shimmering tails, seahorses that glittered like jewels, and dolphins that sang in soft, musical voices. The women seemed to fit right in, laughing and playing with the creatures.

Percy watched from the shore, amazed at what he was witnessing. His hypnotism had taken them to a magical world he hadn't known existed. He felt a strange mixture of guilt and fascination, unable to look away from the enchanting scene.

Suddenly, a siren appeared, her voice echoing through the water. She sang a haunting melody that seemed to break the spell, and Percy's mother and the girlfriend blinked, their eyes returning to normal. They looked around, confused and disoriented.

Percy rushed to the water, helping them out and apologizing profusely. He explained what he had done, expecting anger and frustration. But instead, they looked at him with wide eyes, expressing their amazement at the magical world they had just experienced.

"It was incredible, Percy," his mother said, her voice filled with wonder. "But don't ever do that again. Not without our permission." The girlfriend nodded in agreement, still visibly shaken but also captivated by the memory of the enchanting underwater world.

Percy nodded, promising not to use his hypnotism without consent. He looked at the lake, now just a normal body of water. But he knew its secret now. And he couldn't help but feel a sense of awe and wonder, knowing that such a magical world existed just beneath the surface.

From that day on, Percy used his hypnotism responsibly, always with the consent of those involved. And sometimes, on special occasions, they would all visit the magical world beneath the lake, swimming with the magical creatures and reliving the enchanted swim.
