The Malling School, in Kent, retweeted the clip to the 1,070 users that follow its official Twitter account, which has 1,070 followers.
The secondary school has now deleted the tweet, which featured the 'blue-tick' verified porn star Riley Reid.
The clip, which was posted on April 19, has more than one million views and has been retweeted 3,000 times.

Before sharing the porn clip, the school in East Malling, Kent, previously tweeted a series of pictures from a school trip to Kenya where pupils were helping to paint a classroom.
The account was also spotted following eight others linked to the sex industry, before they were rapidly unfollowed.
One of the school's Twitter followers, a 19-year-old man whose brother is a pupil, said: "I'm shocked.
"It's not what you'd expect of a school's Twitter feed."
He added: "It makes you think about how it got there."

Last year, the head teacher of Oakwood Park Grammar School in Maidstone, Kent, blamed hackers after a pornographic tweet was "liked" from his Twitter account.
The Malling School has been approached for comment.
Local web users mocked the school for their kinky web blunder.
One, using the name 'Disgusted of Tunbridge Wells', wrote: "This is absolutely disgusting.
"Can someone provide a link to it please? I need to view it to make sure that I'm really disgusted."
