"time to see your sparkie limbs," sam asks as you focus on your human arms. You feel your fingernails pop off, one by one, as they're replaced by longer, sharper claws. Thick webbing soon overtakes the gaps in your finger and thumbs, testing the rubber textured membranes by moving your fingers every way you can. The skin on your hand becomes moist and sticky as tan scales form over them and up your arms to your shoulders. Your arms spasm here or there as you feel muscles expand and fins growing on your wrists and forearms.
"so aren't eels...you know...electrical? she asks as she pauses her drawing.
"well, most eels aren't in nature, however seeing we are dealing with merfolk and the fantastical in general," you say as you do one more change. You've been holding back this change for a long time, scared of the effects that your electrical powers could have while changing everything else. You put your hands together as a faint glow comes from them, and you feel the energy flow through you as bright glowing lines form up your tail, over your adamant, and down your arms. Soon sparks go from one hand to the next, then straight lighting links, you give a little light show as the smell of ozone fills the air. This also gets your dual cocks out of your slit as the feeling of electricity is just a real turn-on for you.
