Dave Portnoy’s sex tape partner has stepped forward.

A clip began doing the rounds earlier this week that showed the Barstool Sports boss naked, sitting astride a blonde woman who was equally naked — except for the black leather dog collar she had around her neck and the metal leash that Portnoy was holding.

It turns out his companion was Instagram model Sydney Raines.

In the video, Portnoy can be seen somewhat vigorously yanking Raines’ neck around by the leash.

“Some might not approve of the video content but it was entirely consensual and it’s unfortunate that it is no longer private,” Raines wrote on Instagram, “but [Portnoy and I] are still friends with no animosity between us.”

She added, “I won’t label this a mistake since we have both taken responsibility for it.”

Raines seemed to suggest that she expected there to be repercussions for whoever was responsible for the leak by adding, “But the fact that it was leaked and posted without our awareness or consent would be considered the true mistake.”

She said that she now plans to “continue my daily life without vexation” and signed the note, “With no apologies, Syd.”

Portnoy also addressed the video after stocks in the company that owns Barstool, Penn National Gaming, took a hit as the video hit the web.

El Presidente responded with a video on Twitter saying, “A stock is down because somebody has consensual sex? Are you f–king kidding me?”

He even urged his followers to buy Penn’s shares while the price was lower.

“I would jump on this dip and I would f–k it,” he said. “No pun intended.”
