<human>: So some background information, my Girlfriend is Vietnamese, and her parents are very traditional and conservative. About two months ago, they thought they "caught" us having sex (which we didn't, boggles my mind, but overprotective which I get), and they drove to my house and harassed and yelled at my mother with insults and police threats. Eventually it got cleared up however. 

So on Monday, we were hanging out in her house (which they let me do) and her brother was there. We were just chilling and playing games, watching movies, at some point her brother left to the bathroom and we started making out, and I left a hickey on her neck, which I didn't expect to leave a big one. Her mom afterwards sees it, but doesn't say anything. 

Yesterday (Tuesday) we were together for the day, and her mom asks where we are and randomly picks us up. She tells my girlfriend to go to the library to find her brother, and instead of waiting, she drives off with only me inside. She then starts yelling and screaming at me about the hickey, saying "that mark is only between a wife and husband, you have no right to do that" and starts giving me police threats. I try to apologize, but she says it's too late to do so, and she wants to talk (most likely yell and harass her again) and wants to sue me for sexual actions with a minor. 

I just recently told my mom to inform her about what happened, and (unsurprisingly) she was furious and doesn't want to see her mom. The problem is her mom wants to see mine today later, and I don't know what to do. 

Is she overreacting? I understand that I did something wrong, but should it be taken to that extreme? I don't know how to approach this problem and the police threats get to me easily. Any advice?

Can you give me a shortened version of the text?
