    The crime of penetration with a foreign object is defined in section 289 of the California Penal Code.

    (A) Any person who commits an act of sexual penetration when the act is accomplished against the victim’s will by means of force, violence, duress, menace, or fear of immediate and unlawful bodily injury on the victim or another person shall be punished by imprisonment in the state prison for three, six, or eight years.

    (B) Any person who commits an act of sexual penetration upon a child who is under 14 years of age, when the act is accomplished against the victim’s will by means of force, violence, duress, menace, or fear of immediate and unlawful bodily injury on the victim or another person, shall be punished by imprisonment in the state prison for 8, 10, or 12 years.

    (C) Any person who commits an act of sexual penetration upon a minor who is 14 years of age or older, when the act is accomplished against the victim’s will by means of force, violence, duress, menace, or fear of immediate and unlawful bodily injury on the victim or another person, shall be punished by imprisonment in the state prison for 6, 8, or 10 years.

    “Sexual penetration” is the act of causing the penetration, however slight, of the genital or anal opening of any person or causing another person to so penetrate the defendant’s or another person’s genital or anal opening for the purpose of sexual arousal, gratification, or abuse by any foreign object, substance, instrument, or device, or by any unknown object.

    “Unknown object” shall include any foreign object, substance, instrument, or device, or any part of the body, including a penis, when it is not known whether penetration was by a penis or by a foreign object, substance, instrument, or device, or by any other part of the body.76
