Family celebration! Fucking in HIS parents' bedroom?

What a brilliant idea of mine! As we've known each other for ages, my best friend invited me to his family party. Man, that was boring, we were so bored! While the whole family was gathered in the garden for a barbecue, I had the great idea of sneaking into his parents' bedroom to have a bit of fun ;). It didn't take him long to realise that I was absent, and he discovered me in the bedroom just as quickly! So what now? Either join in and enjoy the thrill of being caught or go back to the bores?
