I bought this thong to wear as a present for my boyfriend who just graduated from the fire academy. I had never worn crotchless panties before, so I did not know what to expect. Wow! From the moment I put them on while getting ready, I could not concentrate on anything but how naughty these seemed! As a bonus, they fit well and they are very comfortable. BF discovered that I was wearing these while we were waiting in our booth for dinner, and then he couldn't concentrate, either. Or keep his hand out of my "lap". It turned out later that the opening is too small to be...ahem...functional for him, but these panties were a super purchase based solely on the tease and anticipation factor beforehand. Needless to say, he has asked me to buy more pairs!
