When my bitch wife got pregnant from another man I refused to love the boy like my own son. If he wants any kind of affection he has to earn it the hard way.
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
