Delivery guy has to give special service to horny clients

I like my job. I'm good at it too, if I may say so myself. I'm fast, accurate and always polite.

Hi, my package. Just coming.

Look, I really need to go. I have quite a few addresses to visit yet. So if you would be so kind as to sign...

Soon, but first help me. This or this?

Both can work, but why not the real thing?
