Summer time psychos

Summer crazy

Sex no no 

Well, my next door neighbor(sister) has a friend who was over.  This friend use to have a foster home, but fell in love with her adopted son, had sex with him, and is now pregnant with his children; twins.  Her other adopted son, the first son's biological brother, didn't want to stay with his adopted mother because she is carrying his brothers/nephews, so he wants to stay with my sister for the month that he's home from the army. 
I think Social services need to revamp their rules and regulations and perhaps do better background checks because it seems to me that parents should NEVER have sex with their kids whether they are adopted or not.
