Spencer saw what just happened and his jaw dropped. He too thought this was all just hokey stage magic but he was bored and didn't have anything else to do. When he saw the cashier turn into a dick, Spencer dropped what he had been looking at.
The dick looked at Spencer, "May I help you?"
Spencer said, "You don't seem too upset. You just got turned into a dick but you seem calm."
The cashier said, "I'm not just a cashier. I'm the store manager. I've been around magic often enough to get used to it."
Spencer asked, "But you plan on getting revenge."
The cashier said, "This shop is about pranks. That guy just started a prank war with me and I will have the last laugh but I don't intend to harm him or do anything permanent. I just like to play around."
Spencer relaxed but continued to stare at the talking dick.
The cashier said, "You seem like the type that would enjoy pranking people."
Spencer said, "Not typically but there is this one bully that I would love to get revenge on."
The cashier said, "My name is William although you can call me Willy right now. I am about to go on break. How about you help me out and while you help me out, I'll help you plan revenge. You're not going to insist that you're straight are you?"
Spencer said, "Uh, no. I pretend to be straight to avoid trouble."
Spencer jerked Willy off. Willy gave him instructions, "Pull my balls tighter. Oh, yeah, stroke me. pinch my head. Spank my balls. You really have to use me if you want me to orgasm. There you go. Almost there."
Finally Willy shot his load and became human. He didn't bother to get dressed since Spencer had already seen his privates.
Willy said, "Thank you. Just for that, I'll give you a dicking wand for free. Stay and have lunch with me and let's plan revenge."
