Oh a TF Ray gun, for sure! Maybe a logo for Pleasure Island Brand Cannabis or beer? A spellbook full of TF spells. A magical pig tail butt plug. A hypnotic spiral pattern with the message Keep Calm and Become a Rabbit. A pool toy nozzle. A muscle growth pill. A pup face with spirals in the eyes and the words "you are getting sleepy." Hmmm what else ... I've written some stories about a potion called Dumbslut that turns guys into horny stupid muscle boys, maybe draw a vial of that?
Can't wait to see what you do!
