When I and my brother found our that our parents marriage was a complete fake we almost collapsed. I've found out that the person who pays for our life style is not our father but instead is mom´s old uncle to whom my mother pays with sexual favors. On top of this I also find that my father is having an affair with his half-sister, my aunt. For some time I was having an attraction for my brother and feeling very guilty but after knowing all this it made everything easier to append between us.
