No. Take it on face value for now, and accept it as an accident.
If more things occur - then bring it to the attention of your girlfriend. But basically - tread carefully. Driving a wedge into a family is dangerous business.
she was probably just having fun. if she does something again, then id talk to her.
This was the yunger sister just having fun. Don't think anythikng about it. Maybe it was a dare from one of her friends. Just ignore it. And maybe she has a crush on you, and then be SURE to ignore it.
