An old Napier man allegedly wrote detailed diaries about his sexual offending against three young boys.
The 83-year-old man, whose name is suppressed, has pleaded not guilty to sexually offending against two boys over an 11 year period.
He faces 14 charges alleging he performed sexual acts on the boys and encouraged one boy to give him sexual favours in return for money and gifts.
The Napier District Court heard this morning that the man had already pleaded guilty to three charges of sexual offending against a third boy.
Crown prosecutor Steve Manning said the man met his first victim when the 7-year-old's family moved next door.
Manning claimed the man used to pleasure himself in the bathroom as he watched the boy play over the fence.
He became "infatuated " with the boy and wrote diary entries calling him "absolutely gorgeous".
The man invited the boy into his home and began "grooming" him, Manning said.
The eight-year-old once came over complaining of a sore neck so the man convinced him to take his clothes off. He then rubbed himself against the boy.
He was 71 at the time.
The man started giving the boy money and gifts to entice him to keep visiting.
The offending then evolved from touching to oral contact and on one occasion penetration.
The man recorded the offending in his diary, using code such as M1 and M2 which Manning said referred to masturbation.
As he got older, the boy realised the man's behaviour was wrong, but kept visiting him because he gave him money.
The boy, who turned 20 this week, told police: "I surrendered to it."
The police were alerted to the offending after the boy confided in his mother last year.
It is alleged the man also touched another boy from the neighbourhood against his will.
After the man admitted offending against a third boy, he tried to justify his behaviour to his adult son by saying he was in love with the boys.
"In his own mind he believed he loved these boys and that expression was in some form of sexual connection," Manning said.
The trial continues tomorrow.
