I'm splashing around in the tub, getting kind of bored...I begin to explore my new form, touching my very sensitive neck gills, and pulling on my wet nipples, I stroke my fins and become more and more aroused...I try to touch my vagina...but there's nothing there...except a small patch of sensitive scales...I play with them, stroking and rubbing and poking, getting hornier and hotter...but nothing happens...how can I cum
