It could be that the teacher has a very traditional view of gender roles and believes that boys should be more 'feminine' in some aspects. So, the teacher starts to give the boy tasks that are usually associated with girls, like doing embroidery or cleaning in a very meticulous way. And through a system of rewards and punishments, the boy is made to comply more and more, until he becomes a sort of'sissy slave' to the teacher.
One possible plotline could be that the teacher uses psychological manipulation. For example, the teacher might constantly criticize the boy's masculinity in a subtle way, making him feel inferior. Then gradually, through giving false 'praise' when the boy behaves in a more 'feminine' way according to the teacher's view, the boy starts to conform more and more, becoming like a'sissy slave' in terms of always following the teacher's commands without question.
Perhaps the story could start with the boy being bullied at school for being different. The teacher, instead of helping him in a proper way, starts to enforce certain 'feminine' behaviors on the boy as a way to 'protect' him. Like making him wear more 'feminine' clothes to school so that he won't be bullied. But this gradually turns into a situation where the boy feels he has to do whatever the teacher says, almost like a slave, losing his own identity in the process.
