Draw faces on each of your boobs and stand in front of a mirror. Have them talk to each other for at least 5 minutes. An in-depth, meaningful conversation (move them with your hands when they talk). Oh.. and you should join in. Don't be rude.
Take photos of your new friends and keep them on your camera/phone/computer for a week.
18/f
Nothing too public (can be in public but secretly) and no insertions!
