Well, let's look at the California law on sexual battery. Are the elements all there? Might be a longshot.
243.4 PC (a) Any person who touches an intimate part of another
person while that person is unlawfully restrained by the accused or
an accomplice, and if the touching is against the will of the person
touched and is for the purpose of sexual arousal, sexual
gratification, or sexual abuse, is guilty of sexual battery. A
violation of this subdivision is punishable by imprisonment in a
county jail for not more than one year, and by a fine not exceeding
two thousand dollars ($2,000); or by imprisonment in the state prison
for two, three, or four years, and by a fine not exceeding ten
thousand dollars ($10,000).
