Suddenly, you feel your legs starting to tickle. You look down to see some blue and green scales growing on your legs. You reach down to feel them, and you find out that in your hands are growing webbing between your fingers and nails disappear, as well as your belly button. Your skin turns green and scaly, and you grow fins on your forearms. You feel an itch in your head and reach with your hand to find that instead of your hair, you have fins. That starts at begins just above your forehead and go all the way to the base of your neck. It reminds you something like a Mohawk on your head with the addition of 2 more smaller fins on each side of your head.
Now your face starts shifting around and more green scales appear and spread around your face, leaving you all green and scaly. You also have ear fins now, your nose shrank into your face until there was nothing left but a smooth surface. Your teeth are sharper now, your iris change color to a bright yellow and adjust to help you see underwater. Now your chest starts tickling, and you look down and see your scaly breasts growing bigger. Two B cup breasts stick out of your chest. 3 slits open in your ribs, so now you got gills.
You can feel how sensitive your breasts are by massaging them with one of your hands. While the other hand reaches down and to feel your new vagina instead of your cock, and as you do, you realize your legs have morphed into a fishtail. Finally completing your transformation into a Siren.
“ Hmm someone rather happy with their new form "“ You turned me into a god dame mermaid and for some reason I feel horny … Ugh, just turn me ba..." You do get look at yourself at the reflection in the water, and you are horrified. You have a mermaid tail and your upper body looks similar to the creature from the black lagoon.
“ AHHHHH what the fuck you turned me into a fish freak "
" Wrong I turned you into a Siren ".
