It's been four days since the last time we saw the two of them together, and now we find out that they're going to have sex again. This time, it's going to be "polynesian sex" . In other words, you can have sex with someone who isn't your partner, but you can't touch their private parts. That's right, we're being tested. Okay, now we get to see what it feels like to be in love with someone other than your partner. We're not exactly sure what that means, but we'll find out soon enough.
