Nude on the Ramp at School

This is about a female friend in school that wanted to be naked in public and asked for my help with do it. She is a pettie woman with very small next to nothing for tits. She had sex for the first time just months earlier and it was in her ass. That was the only time she had any attention from men and she wants more. She asked me to pull her dress off of her leaving her naked in the hallway during classes changing. She said she wear nothing under the dress. No panties or bra and she didn't want to know when tomorrow I was going to do this. I decided to do it after english class because she has to walk down the big ramp to the other end of the school. This ramp is the only connector between the two ends of the building.
The day has come. She has the dress on and she keeps smiling at me knowing what would happen. English class is now over and we're just started walking down the ramp. I come up behind her and pull the dress off over her head. She is shocked and excited. I took the dress with me as I went down the ramp looking back at her. She thinks I'm going to drop the dress so she can put it back on, but instead I throw it over the railing to the lower ramp. She can't beleave I just did that. I keep going not knowing what is going to happen with here now. After school she calls me over to her house. She opens the door wearing the dress again. She said everone saw her naked. She got called to the office and was asked who did this to her. She told them she didn't know because the dress was over her face and then she was tring to cover herself. They don't know it was me.
She said I missed a good show, but now I get a private show in her room. We go up to her room and she says take my dress off again. So I did. She is naked again and she tells me I can do anything I want with her, and I did. Tieing her up. Sticking my dick in every hole she had. Sometimes many times. She was loveing it.
