Brother fucked his sister after spying on her in the shower

Older brother came home from collage. He was laying in the bed all time and acting like a jerk. Didn't even talk to the parents.
His attitude made his sister very mad and she yelled on him. But what brother did after that is totally indecent. He started spying on his naked sister in the shower and masturbate. When sister saw him with hard dick she got furious. But instead of leaving bathroom brother started touching her and tried to have sex with his sister. Girl tried to fight back but strong male took over her. Older brother fucked his sister in the shower. Can you imagine that she liked it?
After incest sex she went to his bedroom and asked for sex again. Now they have lots of brother-sister sex and aren't afraid to have children even when he cums inside.
