Downloading Rule of Three

For over ten years, Laura and Sonia have built a relationship founded on respect, trust, excellent communication, and strong emotional responsibility. One could say it's a relationship anyone would envy.

This includes occasionally opening their relationship to, as they admit, have some fun.
