for a delivery guy, so whatever I was wearing before he came, I am wearing when he shows up. Everything from bikini to bathrobes and lingerie. The time I can remember most recently was when a guy from Delicious Deliveries delivered sushi and I was walking around in my bikini this fall, and I leaned over to grab the bag with food and one of my titties fell out from the bikini top and I didn't notice until it was too late. I will never forget the look on his face, when I calmly put "it" back inside the bikini top.
But I also have a story where the repair guy of my refrigerator came back 2 days later to "check" on it. I had worked late at the hospital in 1990 and woke up by the doorbell the following morning, really early, and outside is this guy wondering if my fridge is all working, and so I told him to come in (I am just wearing a bathrobe) and we walks to my kitchen and we got talking, and before I know it, I have made coffee for me, and asked him if he wanted any. While chatting in the living room, drinking coffee he suddenly stood up, walked up to me, and threw him self on me, and we totally made out and ended up in bed...that was fun. He later confessed that he had seen pictures of me in my apartment and he just had to come back when I was home, so it had been all planned by him in advance.
I would probably never do anything with a delivery boy because I would never be sure in advance they are really sending a guy. Sometimes women shows up...lol. Not that I wouldn't do anything to a woman, but it is different. On another note, I have a few stories to tell about hotel guys though, delivering food and other things to my hotel room. THAT have been much more fun
