<human>: Hey guys, so tonight I took my girlfriend out and we ended up back at her place. We were downstairs and one thing lead to another and we were having sex. We heard footsteps upstairs, and she ran to the bathroom, her dad then knocked on the door at the top of the stairs and asked to come down and grab a beer.

I really had no option but to say sure, and threw my clothes behind the couch, and layed on the couch covering myself with a blanket that was there. He grabbed his drink (talking to me the whole time) and even stopped at the bottom of the stairs, we took another minute to finish our conversation, we wished eachother a goodnight, and he left.

My girlfriend came out of the bathroom and saw I didnt get my shirt on and was terrified. She's convinced her dad knows and was unconsolable for the next hour or so until I left.

Ive been going out with her for almost 4 months, and have known her and her family for over 3 years. She cant just play it cool and hope it slides, and is terrified. Whats everyones take on this? What should we do?

Give me the gist of the text in a nutshell
