I do have fun with my potter fanfic… even had a toffee that turned hair jet-black (that was it). Poor Ron when Ginny thought she was giving a midnight blow-job to Harry…. Potions to elongate the todger (Harry didn’t read the label, took the WHOLE package, ended up with one towering up to 40’ high). Oh, and the magical condom, a spell that’ll allow for perfect sex, only price is losing your magical abilities for the next 48 hours.
