A general amateur couple who applied for a couple's rut consultation challenges the solution of "play with the opposite sex as much as you want without worrying about your partner"! We exchanged partners with each other, and in a closed room separated by a thin wall, we were alone with another's wife / husband ... As we deepened our friendship, such as counseling about each other's sexual life, it became an atmosphere like a real newlywed couple. Close it up! ??
