My parents remarried after a period of separation. So his stepsister Natsu also returned to live with the family after living with his father. Natsu is now a beautiful young girl, no longer as childish as before. Time flies so quickly, seven years have passed. I am now grown up and have awareness about love, sex and women. So seeing my stepsister made me feel extremely hot inside, especially my cock. One day when my parents weren't home, Natsu and I invited each other to do some adult fun.
