"We got out, started making out, and things got hot and heavy quickly, and we ended up having sex against the side of the car as well as on the hood of the car," she told me. "The idea of risking getting caught sends an adrenaline rush and really gets people hot and bothered. It’s that excitement that interests people and really gets them into it. Personally, I don’t think there’s anything more thrilling than performing a lewd act in a very public area."

Dahlia Drake's most memorable moment of exhibitionist sex involved fucking against a parked car at 2 a.m. It was dark, but she and her partner were in full view of a business's security cameras.

Welcome to Rule 34, a series in which Motherboard’s Samantha Cole lovingly explores the highly specific fetishes that can be found on the web.

As a cam model, Drake is used to showing off her sexuality in front of others. Usually, this means performing in front of a small audience watching a stream, or sending videos and pictures to paying customers. On her own time, however, she enjoys getting lewd in public.

"The main reason I do it isn’t necessarily because fans request it, but because I legitimately enjoy public play," she said.

"It makes sex into an adventure and that adventure ends in passion," Raven Risque, an art model and fetish model who often plays publicly, told me. "You are nervous and scared but delighted and turned on... Everything feels heightened because of the adrenaline of being caught, of being seen. Sometimes I even want to be seen."

Every once in a while, a video of people getting intimate in public goes viral. Tabloids pick it up, and suddenly everyone has an opinions about public sex. Last month, it was a duo on a New York City subway platform. In the past, it's been bus riders, a guy with his ass out trying to copulate with a pile of leaves, or Yankees fans.

Sex in public can be fun. It can be gross, regrettable, thrilling, passionate, and inadvisable all at once. But in a time when everyone has a smartphone ready to record or post your sexcapades to the internet, it's a lot harder to get away with it without going viral.

FUCK THE CAR, CALL THE COPS

In 2018, a drunk Kansas man refused to stop fucking the tailpipe of a car until someone tased him. Was he horny for cars, confusing the car with a person's orifice, turned on by the public nature of the car-fuckery, or just very drunk? It doesn't matter—he was charged with "lewd and lascivious behavior." Because in this country you can't fuck anything, let alone someone else's vehicle, in broad daylight.
