¶1The defendant was convicted by a Superior Court jury of two counts of rape of a child with force, one count of the lesser included offense of rape of a child, and one count of indecent assault and battery on a child under the age of fourteen. He contends on appeal that the admission of certain testimony violated the “first complaint” doctrine, and that his conviction should be reversed because of the judge’s failure to exclude a juror for cause. The defendant also claims error in the admission of a photograph in evidence as well as certain statements made by the prosecutor during summation. We affirm.
¶2Background. The evidence presented to the jury included the following. The defendant sexually abused a thirteen year old girl, whom we shall call Tina,
¶3The defendant also acknowledged his guilt on two other occasions. First, Tina, her father, and her mother confronted the defendant about four years after the event, and each parent testified at trial that the defendant admitted to them on that occasion that he had been “inappropriate” with their daughter and that he apologized to her. The defendant’s girlfriend also testified that the defendant told her that “he had really made a mistake,” that Tina had put her hand on his crotch and down his pants, and that she had kissed him first. The defendant’s girlfriend testified further that the defendant asked her whether she would visit him and write to him if he went to jail.
¶4*231First complaint. The defendant does not dispute the admission of the first complaint made to the friend approximately one week after the assault. Rather, he argues that the judge’s allowance of testimony regarding the repetition of those allegations, in several other instances, was violative of the first complaint doctrine. See Commonwealth v. King, 445 Mass. 217, 241-248 (2005), cert. denied, 546 U.S. 1216 (2006).
¶5During trial, the prosecutor presented testimony from Tina as well as several other witnesses who testified to multiple conversations about the rape.
¶6In the instant case, the defendant made multiple inculpatory statements in the presence of the friend, Tina’s parents, and his own girlfriend. These conversations
¶7The admission in evidence of these additional conversations violated the first complaint doctrine. However, in view of the overwhelming evidence presented by the Commonwealth, including multiple admissions of wrongdoing by the defendant, we conclude that the error created no prejudice.
¶8The admission of testimony by Tina that she spoke to someone in the district attorney’s office and to a detective benefits from no claim of context and was also error. See Commonwealth v. *233Stuckich, 450 Mass, at 457 (2008) (“The fact that the Commonwealth brought its resources to bear on this incident creates the imprimatur of official belief in the complainant. It is unnecessary and irrelevant to the issue of the defendant’s guilt, and is extremely prejudicial”). Again, we refer to the strength of the Commonwealth’s evidence as a whole and note as well that the reference to the two conversations during the prosecutor’s closing was fleeting. Accordingly, the defendant was not prejudiced, as the evidence had “but very slight effect,” if any. Commonwealth v. Flebotte, 417 Mass. 348, 353 (1994), quoting from Commonwealth v. Peruzzi, 15 Mass. App. Ct. 437, 445 (1983).
¶9Admission of photograph. At trial, the prosecution introduced a photograph of Tina from the time when the rape occurred, several years before the trial, to which the defendant objected as appealing to the jury’s emotions. This was not error, as demonstrative evidence of Tina’s relative size and immaturity, such as the photograph at issue, was relevant to the element of constructive force, a contested issue in the case, and was not unduly prejudicial. See, e.g., Commonwealth v. Armstrong, 73 Mass. App. Ct. 245, 255 (2008).
¶10Closing argument. The defendant argues on appeal that the prosecutor’s closing improperly referred to Tina’s multiple complaints to bolster her credibility. The defendant’s trial counsel did not object or request a curative instruction. “Although not dispositive of the issue, the absence of any such request from experienced counsel is some indication that the tone, manner, and substance of the now challenged aspects of the prosecutor’s argument were not unfairly prejudicial.” Commonwealth v. Toro, 395 Mass. 354, 360 (1985). We note as well that the references were brief, that they were made largely to refute the defense that Tina fabricated the assault, and that the prosecutor’s closing emphasized the defendant’s multiple admissions. Furthermore, the judge instructed the jury that the closings were not evidence. As noted, supra, the evidence of the defendant’s guilt was strong and pervasive. Even if error, there was no substantial risk of a miscarriage of justice.
¶11Jury selection. Finally, the defendant alleges error because the judge did not excuse a juror who disclosed that his son had *234been sexually assaulted twenty years earlier.
¶12Judgments affirmed.
¶13A pseudonym.
¶14At trial the friend also confirmed this conversation.
¶15In a separate incident, after Tina’s brother confronted him at his apartment, the defendant told his girlfriend that Tina “used to throw herself at him.”
¶16In addition to the first complaint testimony involving Tina and the friend, the following conversations were part of the evidence presented to the jury: (1) Tina testified about a conversation in which she discussed the assault with the defendant when the friend was present; (2) Tina testified to a conversation with her sister and brother; (3) Tina testified to a conversation with her mother, father, sister, and brother; (4) Tina testified that immediately after the conversation with her family, she and her parents confronted the defendant about the rape; (5) Tina testified to a preliminary conversation when she first arrived at the police station; and (6) she testified that she was interviewed by a detective. In addition, (7) Tina’s sister testified that she had a conversation with Tina and their brother; (8) Tina’s mother and father testified regarding a conversation with Tina; (9) Tina’s mother and father also testified about their confrontation with the defendant; and (10) the defendant’s girlfriend testified about the confrontation between Tina, her parents, and the defendant at his apartment.
¶17These conversations are numbered 1, 4, 9, and 10 in note 4, supra.
¶18These conversations are numbered 2, 3, 7, and 8 in note 4, supra.
¶19Aviles, supra at 72-73, establishes an abuse of discretion standard for the admission of subsequent complaint evidence. Because we conclude that the evidence of so-called “contextual” conversations did not prejudice the defendant, our result remains unaffected.
¶20The record suggests, albeit inconclusively, that objections to almost all of the conversations following the first complaint were preserved. We review all of them under the prejudicial error standard.
¶21Members of the same district attorney’s office also prosecuted the case involving the juror’s son.
