Before MURPHY and FAGG, Circuit Judges, and GOLDBERG,* Judge of the United
      States Court of International Trade.
                                   ___________

FAGG, Circuit Judge.

      Aaron Jorge Diaz pleaded guilty to receiving child pornography. At
sentencing, the district court** increased Diaz’s offense level by four under U.S.S.G.



      *
       The Honorable Richard W. Goldberg, Judge of the United States Court of
International Trade, sitting by designation.
      **
       The Honorable Harold D. Vietor, United States District Judge for the
Southern District of Iowa.
§ 2G2.2(b)(3) (increase required if child pornography “portrays sadistic or
masochistic conduct or other depictions of violence”).

       On appeal, Diaz contends his images of child pornography were not sadistic,
masochistic, or depictions of violence within the meaning of § 2G2.2(b)(3). We
disagree. We have defined the term sadism as the infliction of pain on a love object
to obtain sexual release, and as delight in physical or mental cruelty. United States
v. Wolk, 

, 1008 (8th Cir. 2003); United States v. Parker, 

,
847 (8th Cir. 2001). We have defined violence as the exertion of physical force to
injure or abuse. 

in this case depict the sexual penetration of a minor
girl by an adult male with his penis, a young boy performing fellatio on an adult male,
an adult male performing anal sex on a minor girl, prepubescent girls performing
fellatio on an adult male, a group of adolescent boys ejaculating on a grimacing
prepubescent boy, and an adolescent male performing anal sex on a young boy. We
conclude the images are sadistic or depictions of violence within the meaning of §
2G2.2(b)(3). See 

; United States v. Hall, 

,
1261-63 (11th Cir. 2002) (images showing vaginal or anal penetration of a
prepubescent minor by either an adult male or a foreign object is sadistic within the
meaning of § 2G2.2(b)(3)); United States v. Lyckman, 

, 238-39 (5th Cir.
2000) (when pornographic image shows an adult male engaging in sexual intercourse
with a young girl, the conduct shown is sufficiently painful, coercive, abusive, and
degrading to qualify as sadistic or violent under § 2G2.2(b)(3)); United States v.
Canada, 

, 264 (5th Cir. 1997) (same).

       Diaz also argues the Government did not show he intended to receive the
sadistic or masochistic images. Diaz did not raise this issue in the district court, and
appellate review of the issue is foreclosed by Diaz’s plea agreement. Besides, we
have already held that § 2G2.2(b)(3) has no express intent element and that we will
not read one into it. 

.

      We thus affirm Diaz’s sentence.
