An Oklahoma high school is under investigation after a viral video of students sucking and licking one another’s toes at a school-sanctioned fundraiser exploded this week.

The disturbing footage shows at least four kids from Deer Creek High School lying on their stomachs on what appears to be a gymnasium floor furiously lapping up peanut butter off their peers’ bare feet.

“He is devouring those!” one student can be heard saying, as others cheer in the background and an MC moderates the bizarre competition.

The video racked up nearly 50 million views on social media in just 24 hours — and led to a formal investigation by the Oklahoma State Department of Education.

“This is disgusting. We are cleaning up this filth in Oklahoma schools. Our agency is investigating,” state Superintendent Ryan Walters said on X.

The video was filmed Thursday at the Clash of Classes assembly, which was part of the high school’s week-long fundraiser for a local coffee shop that employs people with special needs, according to the Deer Creek School District.

Students from 9th through 12th grade volunteered to participate in a plethora of class competitions that their peers paid to attend — including the toe-sucking tournament.

Administrators initially applauded its students for their involvement in its Wonderful Week of Fundraising, which raised $152,830.38 — but later apologized to its student body and parents.

“There is a video circulating on social media of one of the activities that involves students only during this assembly that has, unfortunately, gained national attention,” the district Saturday said in a letter shared with The Post.

“We want to stress to our community that much of the information accompanying this video is inaccurate. However, through this specific game we failed to uphold the dignity of our students and the proud image of our community. We have a responsibility to protect our Antlers and showcase them in a positive light. In regards to this one particular activity, we fell short and for that we greatly apologize.”

“Thank you for standing with us and helping us to weather this storm and move forward together. “

Despite several students eagerly participating in the games, the peanut butter toe-licking left others feeling unsettled.

“It was surprising,” an anonymous student told Fox 25, which originally obtained the footage.

“I didn’t think they were going to do all that. I was just shocked. I didn’t really have like a feeling. I was kind of disgusted, and then kind of glad I wasn’t over there.”

One parent described the competition as “excessive,” while another accused the school of not thinking things through.

Texas Sen. Ted Cruz called the activity “child abuse” on X, to which Walters replied: “Completely agree. We are stopping this in Oklahoma.”

Walters’ office could not immediately share the status of the investigation.
