(Really embarring) What you you do?

I've only known this girl for two and a half weeks. Normally I wouldn't sleep with someone so quickly, but it happened. My problem is that a video of myself and her in the act has been shown to both her family and my (unofficially adopted) family and around 10 other people. It was all done in fun by a mutual friend but obviously we aren't happy. Neither of us have seen any of the people since the video was shown. We are both adults (30 and 27). I mean seriously do you think the people who watched it will be mad, so far all we know if what we have been told by text. Apparently my 17 year old adoptive sister saw a glimpse, so I'm guessing that won't help. Fortunately it was mostly under the bedding. Are they all just going to laugh it off or will her father square off with me?
