It’s reading, writing and writhing.

Hundreds of city teachers are boosting their incomes through lucrative liaisons with sugar daddies, according to the dating website SeekingArrangement.com, which pairs attractive young people with rich, typically older romantic partners.

“Sugar babies who want to live their lives and better their careers can’t, especially when they are working multiple jobs,” said the site’s CEO, Brandon Wade.

“Having a mentor or partner who exceeds what they already bring to the table can allow them to focus on their goals and achieve the lifestyle they strive for.”

A total of 451 Big Apple teachers, mainly women, are engaged in extracurriculars with SA’s well-heeled “daddies,” according to the site.

The majority hail from Brooklyn, where 206 of the sugar-baby educators have sought connections. Another 83 call Manhattan home, while 74 live in the Bronx, 58 in Queens and 30 on Staten Island.

And it’s not just in the city that never sleeps where teachers are taking on a second job of bedding the wealthy.

There are 1,489 sugar-baby teachers living in the state overall. That’s 14 percent of the total of 10,000 Seeking Arrangement’s sugar babies who identified themselves as educators.

The average age of the Empire State teachers on the site is 27, but the range spans from 22 to 56 years old.

New York ranked No. 2 behind California for the total number of sugar-baby teachers.

Texas and Florida came in third and fourth, with 1,302 and 999, respectively, according to an Orlando Weekly report.

Seeking Arrangement couldn’t say what grade level the educators teach or whether they work for public or private schools.

The average teacher’s salary in New York state was a highest-in-the-nation $79,588 in 2017, according to a Rockefeller Institute of Government analysis of state Department of Education data published in April.

That report also found that the wages of New York state teachers who have bachelor’s degrees has grown commensurate to the salaries of others with a BA between 2007 and 2017.

Starting annual salaries for city teachers with a bachelor’s degree average $57,000, while teachers with a master’s clear around $63,000 when they start.
