Wrong with fantasising till your hearts delight. Keep doing it Alvin TX sex dating until your fullfilled. Its just a fantasy and as as you are not living it out and pursuing your sister fantasies are completely for your mind and psyche. Sexual fantasies are just that its natural and fine. It is imoral when people cross the line and do taboo things are not considered acceptable by society or religious law. If you are not able to be comfotable and come to terms with accepting it as only fantasies then I would suggest taking steps to phase out the and delete them. Dont be so hard on your self its undetstandable. Alot of these replies below are haters and too quick to judge.
