I tricked this kid into showing me his thing
Why would you trick someone into doing this?
I heard very interesting things about his piece.
It's natural to be curious about your peers development, but its wrong to ask them to expose themselves. If someone had caught you then you could get into a lot of trouble and possibly suspended from school.
I don't think these things are serious.
It is serious, especially if you are tricking someone. It can be seen as a sexual crime.
