While you continued to suck Damon's dick. You felt something strange happening to you as the two of you change.
You and Damon grow slits, on your sides, as you now had gils. You felt your nipples grown into your new breast cover in seashells.
Damon meanwhile grown musscles as he now had a stronger upper body. Both your legs fuse together into your new limb.
Damon grew blue scales while you grew red scales. Your hair then grew longer as your face become feminine.
Your privates then change to match your new form as both your changes finish as your toes become your new tail fins.
Damon then blows his load, into your mouth, as your changes were now done. After sucking his dick. You realize your, and Damon's changes, and freak out.
"Damon I'm a mermaid and your a merman." Damon notice his changes as well. He was shock as well.
"How did this happen to us?" You notice the pook water was glowing and realize the pool change you.
"It must have been the pool. It must have change us. I didn't expect this to happen." You told Damon.
"We can't be the other ones who were change. Maybe other people change as well." Said Damon.
"Damon do you still love me?" Damon swims over to you. "Of course Elliot. Or Eillen now. Nothing will change that." You felt happy Damon still loves you.
