She stated to the judge Ruben had engaged in this activity with the young males "for many years", and youngsters had earlier experienced illness the next day.
She explained Ruben had been successful in rationalizing this for many years as the minors being "overstimulated by activities", until his stepchild had suspicions in recently.
