Two years after a pair of Brooklyn actors spent the night together, one has recreated the date as a rape in a play.

Donaldo Prescod claims his encounter with playwright Mariah MacCarthy was “completely consensual.” MacCarthy never said anything to him or the authorities that she thought otherwise.

So Prescod was shocked on Dec. 9, two years later, when MacCarthy wrote a lengthy Facebook post saying she’d been raped, and named him as her attacker, he says in a lawsuit.

“Safety first, folks. Don’t work with rapists,” she wrote.

In January, MacCarthy debuted a new play, “Safeword,” at downtown theater Dixon Place.

“The central character recounts several instances of having been raped . . . The rape instance about which she goes into the most detail recounts almost verbatim the assertions set forth in the ­defamatory posting,” Prescod alleges in Brooklyn Supreme Court papers.

Prescod says in the $800,000 legal filing against MacCarthy that he’s no rapist.

“At no point did defendant say ‘stop’ or otherwise request that plaintiff stop penetrating her,” he charges. “ To the contrary, defendant actively encouraged plaintiff to continue.”

The sex began as consensual, MacCarthy wrote.

“I was not drunk or coerced into this. I 100% [sic] planned to have sex with you,” she said.

But they had no condoms, so they agreed to stop, even though they were already in bed.

“At some point after you said, ‘We’re not gonna go there,’ you penetrated me. I thought to myself, ‘Didn’t we just both say we’re not gonna go there?’ ”

She told Prescod to stop, but after a few seconds, he kept going, she alleges.

“This was rape,” she wrote.

MacCarthy says in her post that she “did everything I could NOT to name this man publicly, for nearly two years,” but that telling the story in private “wasn’t enough. I needed to name him.”

Prescod says MacCarthy never reached out to him, and he has been shunned by the New York theater community since her post, which received 270 likes and 73 comments.

He wants a court order barring her from posting her rape claims, and is asking a judge to force MacCarthy “to publically [sic] admit that the defamatory posting was false.”

MacCarthy, who removed her Facebook page within hours of an inquiry by The Post, did not ­return messages seeking comment.
