Hi a long time ago, i read a manga that was about this horny student who went around and just fucked the teachers and some girls from the school. if it helps, one of the scenes i remember is that a science teacher was using a test tube as a dildo. I'm not talking about golden boy, this is a different manga, so anyone know of it? Thanks.

There was a scene with that tube you described in Angel, check Volume 3
