She cover for me

Then she decided: “What are you talking about?”
“A naked man entered the store. Where is he?”
“I didn’t see any man and even less a naked man in the last 15 minutes.” She seemed nervous and I didn’t know if the other girl would buy it.
“But I saw him entered. He must be here.”
“You can check the store but I didn’t see him and I’ll doubt you’ll find him here.”
She made a sign for me to stay put but it wasn’t necessary because I had no intention to reveal myself. After what seemed like a long time I heard the other girl leave, she turned to me: “I’m not sure why I cover for you. I really should have turned you over to her. Start explaining!”
With not much else to do, I started telling her why I was here, naked at her feet. My story wasn’t that long, even if I told all the details, and we were interrupted only once by a customer. Finally, having told her that much, I told her my name and ask for hers. “I’m Helen. Well, I have some stuff to do before closing and since I don’t think you will help, I better start. Stay put and don’t touch anything.”
So I waited behind the counter. She would sometimes come over and serve a client but nobody notice my presence. Maybe 40 minutes before closing time, we were back to chatting (which was a bit weird since I was naked) when I heard a customer entered and Helen seemed to know her very well.
“Hi, are you coming to the party after?”
“No, I don’t think so. That’s not really my thing.”
“Oh come on, I promise it’ll be fun!”
“No, really. Plus, something happen and I think I’ll be more fun.”
“What happen?”
“If the party is boring, come back here when I close and you’ll see.” Shit, I didn’t want someone else here when we leave.
“I don’t know. Sometimes you’re surprise are not that much fun. Come on, tell me now!”
“You free to decide but I’m pretty sure you’ll like this one. If you don’t come, I’ll tell later I promise.”
“I’ll think about it. See you late”
“Bye”
Helen looked at me and saw that I was a bit mad and a bit uncomfortable about what had just happen. “Oh come, on. I’m sure you will like Emily and I’m also sure she’ll really like you.”
I almost decided to give her the silent treatment but since I was hoping she would help me get home, I rethought my decision. So we continued talking about a lot of things. Of course, being naked in a store, we talked about dare and how daring she thought I was. I told her I was scared but she insisted that she was almost jealous of how brave I was. She even thought I could do more but I told her never again. She got a glint in her eye that told me she had an idea but even when I pried she wouldn’t tell me. Finally it was closing time but fear grip me as I realize that maybe her friend was now there.
