Flashing the delivery driver

I (29F) ordered delivery tonight and was feeling horny and wanted to have some fun so I stripped down to nothing but a short, skimpy black silk robe. I tied it loosely so as I was walking around the house my pierced 32d tits were constantly slipping out. When my order finally arrived I made sure to be waiting by the door so I could take it from the driver personally. When I reached out to take the bag from him, my right tit slipped out as expected. I went to adjust my robe but in my nervous fumbling I accidentally pulled the sash and untied it. It hung open just an inch or so but he definitely got a nice view. He laughed and told me to have a nice night before turning to leave. I just smiled nervous and frozen, in awe that I actually flashed a random delivery driver. Now I'm back inside and sooo horny and mad at myself for not inviting him in!
