My son got kicked out of school for letting a girl in the class wank him off. I said 'son that's the 3rd school this year!' 'Maybe teaching isn't for you'
Is that about a teacher sexually abusing a student?
No, it's just a joke.
Child sexual assault can be extremely damaging to children and affect their whole lives. Making light about it can be hurtful, just like you would be hurt if people made a joke about something that caused you pain.
