I was sexually harassed in class and my teacher did nothing

I'm making a painting on my classroom wall bc my teacher really liked art I made. I started doing it today and I need to stand on a chair to reach the wall. When I got on the chair these two boys came in and started whistling at me and talking about my ass. I was trying to ignore them but they came over to me and one sat on the table near my chair and kept rubbing his foot down my leg. They kept being gross and when I didn't say anything one of them threw an empty bottle at me and asked if it was because I was (the r slur)ed (I am autistic). And then they started talking about how disabled ppl are easier to sa. Then they just insulted my painting for the rest of class but I didn't really give a fuck at that point. They also told me to deep throat my paintbrush bc they "were trying to see smt". They obviously weren't actually into me it was a weird bullying thing but I still felt really gross and nauseous. It was probably the worst bullying experience I've ever had. My teacher didn't do shit about it. I've never seen them before in my life idk what their names are or how to report them. I'm a trans guy and I really wish I passed better so shit like this didn't happen.

Edit: I didn't expect this to get so much attention. Yes, I have told my parents.
