Recently my girlfriend told me about how her cousin was having a sugar daddy relationship with a 30+ year old man. She said it was strictly going to be for her company in exchange for gifts and money which I highly doubted considering most of these types of relationships end up with the guy wanting sex. A couple weeks later, her cousin tells her that she's had sex with the man and he gave her a $300 "gift". Apparently, she met him off of an app and lied about her age because she is 17, (app is 18+). She also said that the guy knows she is underage. I don't think I should be the one to tell her parents but told my girlfriend that if she cared about her cousin, she should notify them.

WWBTAs if either of us snitched?
