When you woke up this morning we'd imagine you didn't think you were going to start the day with a look at some video footage of model mates Cara Delevingne and Kendall Jenner bouncing about on a couple of giant, inflatable boobs, but that's exactly what you're about to see.

Yep, it turns out that when you're famous and have a few hours to burn in New York, the only thing to do is swing by the Museum of Sex for - as they described it - a little 'sex adventure'.
