What would you do if...(Girlfriend + flask = ???)?

What would you do if you were out with this hot girl..She has bronzed tan skin, baby blue eyes, long kinda wavy curly black hair, a total 10. She's a real sweetheart, but all the sudden she slides up her short red dress a little to reveal a flask tucked under a black garter. Then she takes a swig. What would you do in this situation?
