Pay for Play.

Hugh Hefner’s son Marston has joined Onlyfans and is hoping to use the income to splurge on Pokemon cards.

The 33-year-old — who is one of the late Playboy founder’s four children — made the revelation in an exclusive interview with Page Six, saying: “It is a long-term avenue for further financial security.”

The Playboy scion — who describes himself as “bisexual AF”— is married to Anna Lambropoulos and the couple is expecting their first child.

However, the kinky content creator admitted that his wife is “not crazy” about his OnlyFans account, where he strips down for paying subscribers.

Most of the content is Pokemon-related, but the young Hefner also has videos where he tantalizes fans by “undressing myself slowly” and engaging in “butt plug play.”

While some might be surprised by Marston’s OnlyFans endeavor, it’s a combination of both of his parents’ professions.

Dad Hugh made a fortune from publishing risque content, while mom Kimberley Conrad is a former Playboy model who had no qualms flashing her flesh.

Martson says his liberal upbringing has made him open-minded about how people make their money, declaring: “I believe that there’s nothing wrong with nudity or sexuality.”

He added: “If people have sex and they make money from it, cool. If I end up doing it, cool.”

While Martson does not share content that shows himself having sex, he said he would support his wife if she ever wanted to join OnlyFans.

“If she wanted to do an open relationship, we’ll talk about it,” he explained. “If she wanted to do anything sexual, that’s a conversation that we have no matter what, and we are always having it.”

Marston is a comic book and Pokemon card collector and says he wants to use his OnlyFans income to add to his haul.

He refused to reveal how much he earns from the content he creates on OnlyFans but hinted that it was a lot, saying that he would be able to afford a Pokemon Trophy card before the end of the year.

Some rare Pokemon Trophy cards can cost thousands of dollars.

Meanwhile, Playboy recently relaunched its iconic magazine as a digital-first publication — in a bid to take on OnlyFans.

The online publication serves as Playboy’s “creator platform” — a subscription site that the brand is selling as an “elevated,” “safe” and “exclusive” alternative to OnlyFans.
