His dreams are now fulfilled.

Jail fetishist Matthew Matagrano, 36, was sentenced to 10 years in prison today for posing as a correction officer and sneaking into the Manhattan Detention Complex earlier this year.

The 300-pound convicted sex offender waddled into Manhattan Supreme Court in a bright orange jumpsuit looking sullen as Judge Ronald Zweibel handed down his punishment for the bizarre July 27th crime.

The former counselor for at-risk-youth spent seven hours gleefully strolling through the White Street facility where he strip searched an inmate, stole a $2,500 walkie talkie and handed out cigarettes.

It wasn’t a first for the Yonkers prison enthusiast – he’s been accused of sneaking into jails in four boroughs.
