It is hard to resist the charms of a teen stepsister and it looks like this is the case with my teen stepson too. When she started dating another teenager, I always thought that it was going to be a good thing. I loved seeing my teen girl grow and I even thought that the closeness could make me feel closer to my girl. But when she started screaming at him in bed, I decided that this relationship was not going to work. I went to the police and explained to them what had happened and they advised me to get a divorce..
