Lilly likes experimenting, but this one experiment might have taken things too far. After an evening of rigorous testing, she awakens to find she's grown a cock! Inspecting her new discovery, she begins rubbing her new cock, liberally applying lube to analyze how it reacts to stimuli. It isn't long until her cock begins to tingle with excitement, then ultimately explode with buckets-worth of cum! The experiment was a RAGING success.
