Girlfriend goes skinny dipping with a stranger watching while the boyfriend films the interaction.
Video begins with the girlfriend undressing herself while the stranger watches her. She grabs a towel and covers (barely) herself while getting into the water. It cuts to the stranger talking to the girlfriend while she is completely nude next to him. She slowly gets out of the water with her back to the guy and he watches her. She then talks to her boyfriend. She poses on a rock and bends over before re-entering the waters.
The gf then gets up on the rocks with her hands covering (again, barely) her breasts. The guy moves closer to talk to her. This a great video of Nao interacting with a stranger while her boyfriend films.
