I am a rabid supporter of girls and women. If I had gotten my hooks into the soon-to-be-16-year-old and had enticed him into (I'm trying not to hurl) being my toy, I would be guilty as heII of sexual abuse. Likewise, an older teenage, 18, 19 or better seducing a "younger than 14" year old. Is the girl 10 or 13? 
Had the statute of limitations not run out, I'd be inclined to press charges against the boys (I call 15-year-olds "boys") whom I - when we.... - that took advantage of me when I was 14, even though I thought it fun at the time. 
There is not enough information in the article to know the age difference and the relationship. I want to know too, who has previously seduced the boy?
