You are so turned on you can't handle it.
Your scaly erection protrudes from your tail, slightly larger, you think, but it's hard to tell, given the changes you've gone through, the lack of hair, and, well the scales, you're not sure. Either way, you were definitely extremely horny and your erection reflected that fact. You'd never recovered this fast before, but you were definitely ready to come again.
You couldn't stop yourself, you reached down and grabbed your dick. It pulsed and became larger, it felt incredible, harder and stronger than ever before. Was this an effect of the tail? or the extra muscle it had granted you?
You keep rubbing and hear yourself moan slightly as you are unable to hold off the explosion that follows.
You feel some wetness on your tail, but close your eyes, and collapse into a heap of pleasure.
