Push a set of shelves over

There was a steel set of shelves with several bottles on it. You give it a shove and it slowly falls over at him. Alex sees the shelf falling and reaches up to grab it, but all the bottles slide off. One of them, a semi clear jug with a translucent purple fluid in it, lands right in Alex’s lap and pours right on hiss massive dick. Alex pushes the shelf away, laughing to himself until the fluid pouring on his penis starts to sizzle.

“Wh-what? What did you do?” The normally confidant Alex had suddenly become very timid. The sizzling of the fluid gets louder and some sort of smoke was coming off Alex’s dick. Suddenly it all came back to you, the skin condition, the cream, Alex’s penis was melting! The area of his penis the fluid touches was turning jet black and disappearing. Alex screamed in horror and looked at you, “Why?! Why would you do that?! Go get my meds, now!”
