I am not a lawyer, but it sure sounds like you are walking on a gray area.
If, for example, the girl is 16, and it's "Uncle Fred", not really her Uncle, a friend of the family, who is 45, and he can't wait to kiss and hug this girl, um, er, well, can you see where that might be interpretted as not so great, right?
If, however, it's "Aunt Gracie", the sister of her mother, and the child is 8, that's probably more acceptable.
You need to be very very careful on things like this.
When in doubt, yank it back a couple of notches.
Questions like this, give me a creepy feeling.
