I was at a military installation of some kind-a hangar, I think.  There was a girl hanging around wearing an open jacket with nothing on underneath it.  I came out of a door, and she opened her jacket all the way and offered herself to me.  I had never had such a direct invitation; I wanted to take her up on it, but there was nowhere around there to do it.  I led her over to a wall and sat her down on my lap, but was kind of embarrassed about screwing her right there.  Later on there were three cheerful-looking bare-breasted girls who offered themselves.  I felt all their breasts and particularly liked the last one's, which were large and somewhat soft.
