Defendant appeals as of right his conviction by a jury of first-degree criminal sexual conduct, MCL 750.520b(l)(a); MSA 28.788(2)(l)(а). We affirm.
Having received alternate weekend and holiday custody of his children after his divorce from their mother, defendant took his six-year-old son and nine-year-old daughter, the complainant, оn a weekend trip in December 1991. After a day of swimming, during which defendant apparently be *556 came intоxicated in the presence of his children and was physically escorted from their hotel swimming pool, the three retired to their hotel room.
Defendant originally shared a bed with his son. However, defendant soon joined his daughter in her bed, ostensibly to have her rub hand lotion on his back, which she did. He then returnеd to his son’s bed. A short time later, he again returned to his daughter’s bed. When his daughter was beginning to doze off, he lifted her nightgown, and, without removing her underwear, forced at least one finger, possibly more, into her genitаl opening. The finger or fingers were, in effect, sheathed by the girl’s underwear. The complainant shoutеd, "Daddy, daddy, don’t,” to which defendant responded, "Well, you don’t have to if you don’t want to.” The complainant told her mother of these events a few days after returning from the vacation. Defendant was subsеquently convicted of first-degree criminal sexual conduct.
Defendant first argues that the trial court еrred in denying his motion for a directed verdict because defendant’s acts were insufficient, as á mattеr of law, to constitute "sexual penetration,” an essential element of first-degree criminal sеxual conduct. We review the record de novo.
People v Morris,
Defendant contends, in essence, that the facts adduced simply do not constitute first-degree criminal sexual conduct as definеd by the statute, and, because of this, the trial court erred in denying his
*557
motion. Statutory interpretation is a quеstion of law that we review de novo.
People v Young,
(1) A person is guilty of criminal sexual conduct in the first degree if he or she engаges in sexual penetration with another person and if. . .
(a) That other person is under 13 years of age.
"Sexual penetration” is defined in MCL 750.520a(l); MSA 28.788(1)(1), to mеan, in relevant part, "any . . . intrusion, however slight, of any part of a person’s body or of any object into the genital or anal openings of another person’s body.” Defendant contends that "therе is no intrusion 'into’ the genital opening where that opening is covered by the victim’s clothing.” We find defendant’s contention meritless. The complainant’s unrefuted testimony established that defendant committed аn act of sufficient physical invasiveness to constitute "sexual penetration.” While defendant аrgues that the complainant’s underwear "covered” her vagina, implying that the underwear was some type of impregnable barrier precluding penetration, the testimony clearly demonstrated that the underwear was forced inward by defendant’s finger. Defendant’s finger, a part of his body, sexually pеnetrated the complainant’s genital opening; we need not consider whether the underwear being discussed may be considered an "object” within the meaning of the statute. The elements of the stаtute were clearly satisfied and *558 the trial court acted properly in denying defendant’s motion fоr a directed verdict.
Defendant next contends that the trial court abused its discretion,
People v McAlister,
Finally, defendant challenges the trial court’s admission of testimony concerning thе involvement of the Department of Social Services. We find no abuse of discretion. McAlister, supra. The testimоny was relevant and admissible because defendant had attacked the credibility of the comрlainant’s mother, the testimony was introduced with limiting instructions, and it served to demonstrate that the mother had acted appropriately.
Affirmed.
