Popping The Pervert

I gave you a potion that makes you swell up whenever youre aroused. Look at you, you must be really aroused because youre about to pop! Dont worry, Ill make sure you do POP! But first Ill tease you with my hot body so you grow rounder and rounder and its easier for me to pop you. Just how should I do it? A pen? My nails? Maybe my heel?
