Your mom knows how much you hate the school principal. Today he made up a completely fake reason to give you detention, but when you got home you understood why he wanted you out of the house. Now he's threatened to expel you unless you stay and watch him
As a stay at home mom I can get pretty board at times. I found out watching my sons fuck each other was a great way to pass the time. So now I 'leave' the house every so often so they don't have to worry about anyone walking in on their brotherly love ses
