Andrea and Luna are challenging themselves to take a very cold bath. The goal is to prep for a trip to Iceland and they are curious to how long they can handle shivering and their chattering teeth. There is no faking here as the girls get frigid and talk about how uncomfortable they are. Little goosebumps form on their bodies and they try to warm each other up by hugging and grinding on each other. When they try to kiss, their lips chatter.
There is not a good way to get warm even as they love on each other, so they huddle in the cold, and wait for the challenge to be over.
