What should i do i saw my teachers boobs?

So in high school I liked my science and English teachers as they were so hot. I started liking my English teacher because I saw her boobs. This is how. Every English lesson u have to read for 10 mins at the start on ur own and silently. So I did that. I sit right at the front opposite the teachers desk. She was on her laptop doing somerhing. That day she was wearing a low top and u could see some boobs cleavage. I was attracted by it and kept on looking. Suddenly she looks up to see if any1 is talking and she sees me looking at her tits. She smiles at me and I look down at my book cuz I was embarrassed. I think she kept on looking at me and was smiling, I couldn't see cuz I was looking down at my book. Later on that lesson I asked for help and she bended down and I saw it again. This time I looked down into it cuz she was closer. She was wearing a bra and I saw she had a learning in her belly button. It looked sexy. She was reading my work and I kept looking at it. I looked for about 25-40 secs while she read my work. Once she was finished, I looked away. She helped me and then went away. Then at the end of the lesson she asks us questions on what we learnt. So she sat on the table on the other side of the room at the front not so far from my table. She was wearing a skirt with a long cut in it.( if u dnt know what it is search on google skirt with cut in it and it will come up but look at the formal ones) so I saw up her skirt and she was wearing a thong it was sexy. She had smooth legs and I wanted to jerk of. But I didn't . Now I'm stuck on what to do.
