Georgia has a big case about this right now. An eighteen year old man and a fifteen year old girl had consensual oral sex. He mother objected after the fact and the young man is doing ten years in prison. Oh- and he was an honor student and in line for several college scholarships. And she was "very mature." TEN YEARS IN PRISON!
As a former 14 year old girl, the mother of a former 14 year old girl and the mother of a former 19 year old boy--- got to tell you- I would question the common sense of your match-up.
No fourteen or fifteen year old is going to admit they "aren't mature," and a lot are thrilled to have the attention of a nineteen year old, BUT NEITHER OF YOU HAS THE COMMON SENSE OR MATURITY OF A SAND GNAT. And that goes for Lamboleum, especially. You are both just looking for a statutory rape charge---or at worse an interfering with parental custody/authority charge.
Back away slowly and stay away until the young ladies are at least 18.
