As our sexual interest in each other increased, I too ...as getting bolder, wearing smaller and more sheer, see-thru panties. I was getting more daring by exposing more of my young soft bare skin to his lustful view each time. This intense sexual game we were playing kept getting hotter each time and we both knew it.
