when i was around in my seventh class i had s***** relation with my sister we felt so attracted to each other , since then we were having times and again some kind of physical contact when i grew up i satarted having guilt about it but we couldnt control our self and some times here and there we did . i have been hating my self about it and feel very upset as a closely gaurded guilt which i finally want to get over . god please forgive me for it ,
