I'm a 19 year old male and my cousin in 18. we are not related by blood because she is addopted. eveer since i was 17 or so she would always "accidentally" walk out of her room or the bathroom without a top on, and would stand there for a few seconds. then she would say omg i'm sorry i didn't see you there. After this would happen i would usually take some of her panties and masterbate in the bathroom. Now she is 18 and wants to have sex. Is this ok since she is addopted?
