I was 14, in school, and we went to watch a movie in a classroom. As there was not a lot of space I was sitting on the first rank, and because people behind couldn't see the screen, I was, like the others, sitting on the floor, my back against the bench.
  There was a girl behind me, who put her feet on the bench, which was probably quite comfortable for her. She was wearing little flat white boots, and her soles were against my back. Realising that I tried to move a bit on the left or right, but she might have found it was funny and she kept her soles in my back. So I decided to lie a bit more so there was just my head (I thought she would not put her soles against my hair).
  But she began to clean her soles on my head. I didn't like that really, and I passed half of my body (head, shoulders) under the bench to talk to her. I just got the time to say something like "What the hell are " and she put one foot on my mouth to stop me. She said : "You don't want me to clean my boots on you in front of the others, right ? Ok, I stop but I'll do it with you in private and you will obey me, right ?". I said yes with my head, and get back to my place, she stopped to clean her boots on me.
  A the end of the movie she catched me, and said : "Let's go for the private cleaning of my boots." I didn't say anything and followed her.
  We went behind a building, and she ordered me to lie on my back. She first put a boot on me, cleaning it on my shirt, then the other one.
  After she stepped on me, walked on me. Then she kicked me a bit, and I turned, now lying on my belly. She walked again on me, on my back. She stopped, walked in front of me and pushed the toe of her boot on my mouth, and said : "Lick the toe of my boot".
  I've done it, licking also the toe of the other boot. Finally, I lied again on my back, she stepped on me and ordered me to lick each of her soles.
  First, I didn't accept, so she put one boot on my face and put a lot of her weight on it. I tried to struggle but couldn't do anything. I finally accpeted to lick her soles, which I have done, cleaning them from the dust of the street. She has never asked me to do it again, it was my first experience.
  At this time I realised I loved that.
