Gif: JUST ONE DROP (Patreon)

He bought a potion to feminize his enemy, but when the bottle arrived it felt much too light, like it was empty. He unscrewed the cap to have a look and a single drop fell out and plopped onto the back of his hand. The drop traveled up his arm, warm and wet against his skin, and as it crawled beneath his sleeve he felt a strange tingle all over. He told himself that he had nothing to worry about. After all, he hadn't swallowed any of the potion. What could just one drop do, if it only touched his skin?
