My parents just legally adopted an 18 year old female from southern China. She is really attractive and incredibly smart. I am really attracted to her, and would like to start dating her. However, would it be weird that she is technically my sister. I am a 53 year old male, in someone good shape. I am 5' 6" and weigh 230 lbs. I think she would be a great match for me because she is 5' 8" and weighs 124 lbs. She can't speak English, but that is ok because my plan is to not be talking, if you know what i mean. ;-) Please give any advice possible. Thanks everyone!
