Residents of a sleepy English town are up in arms over a kinky sex festival heating up their neighboring forest.

About 500 swingers from as far as Romania and Australia descended on Brokes Wood near Kent on Saturday for the second night of Flamefest, an al fresco skinfest featuring event a dungeon, a dominatrix-controlled “adult play area,” and erotic workshops — including one called “Getting Sexy with Snakes.”

The festival’s website touts the three-day event as a descent into “the purest, most hedonistic elements of the party scene, from kinksters to ravers” where the intrepid “explore pain, experience pleasure and fulfill your fantasies.”

But disgusted denizens of nearby Tunbridge Wells their town simply cannot countenance the sylvan shenanigans — and besides, they never voted to approve the event in the first place.

“I’m no prude but this is the wrong place for this sort of thing. It’s a residential area,” Councillor Dianne Hill told Kent Live.

Hill said she received numerous complaints about the sex-filled affair, and added “a big worry is they say there will be coaches (busses) coming down. Where are they going to park? People are obviously going to be concerned about the noise,” Kent Live reported.

Resident Chris Herbert said he simply doesn’t “want a bunch of perverts descending on our town,” the Daily Mail reported.

“These people are coming for an orgy and it’s going to create hell on the roads as the woods can only be got to along a single track road,” Herbert, 42, griped.

Event organizers said they secured a temporary license to hold the event, and didn’t need it to be approved by a council committee, according to reports.

And besides, the organizers insisted, they are not making sex into a public spectacle, the organizer Helen Smedley said.

“We allow people the safe place to have sex, we’re monitors, just to make sure everyone’s safe. There’s nothing that happens in view, on site. People go off to their tents to meet like-minded people,” Smedley told Kent Live.

The fest, which costs about $385 to attend, runs through Sunday.
