You want to go for a swim. You change into your bathing suit, but when you are about to dive in, a hot woman in a bikini approaches you. She asks you if you want to go for a swim and you say yes. Soon, you're both in the water. Suddenly, the woman starts freaking out. When you finally get to her, you realize that her brown hair is longer, her bikini bra is now a red clam shell one, and her legs and feet have been replaced with a red mermaid's tail. You realize what's going on, and that you're next. Your feet fan out and your legs combine. Soon you have a blue tail. Then your hips increase in size and you notice that you're becoming a mermaid, not a merman. Your arms shrink, you lose all body hair, your fingers become longer and more nimble, and your nails longer and more feminine. Then your nipples become erect, and soon you're staring down at 2 DD cups, like the other woman. Finally, a blue clam shell bra that matches your tail materializes on your breasts. Now you're staring down at a feminine body. But what about your face? Suddenly, you feel the change happening. First, your face structure becomes more feminine. Then your nose becomes softer and cuter, your lips, larger, and your eyes wider. Finally, your hair grows down to the back of your new tail, and you feel the transformation is complete. You also notice your hair is now blonde. You and the other woman realize you're the only 2 mermaids in the pool, but then you realize that that won't be for long, as the more people that go into the pool, the more mermaids there will be.
