Warning: Spoilers ahead! Do not proceed unless you’ve watched “Euphoria” Season 3.
Sydney Sweeney left little to the imagination throughout all three seasons of “Euphoria” with several X-rated scenes, especially as Season 3 followed her storyline as an up-and-coming OnlyFans model.
The actress, who portrays Cassie, has been a key member of the cast — alongside Zendaya, Jacob Elordi and others — since the first season of the Sam Levinson-created HBO series premiered in 2019.
Viewers watched as her character got off while riding on a carousel in Season 1, and got hot and heavy with Elordi’s character, Nate, in Season 2.
During an appearance on “The Tonight Show Starring Jimmy Fallon” in June 2025, Sweeney teased that Cassie would be leaning into her “crazy” tendencies in the third season — except that she’ll be “even worse” this time around.
“Being able to go back to Cassie and grow with her, and go even crazier is such a treat,” Sweeney told GQ in November 2025. “It’s such a fun roller coaster ride, because I’m getting to go to all these insane places.”
That has rang true, as fans have watched as Cassie launch her career as an adult entertainer in the latest season — resulting in high highs and low lows for the character.
Sweeney kicked off the first episode of the Emmy-winning series with a bang, as Cassie wore nothing while getting intimate with her then-boyfriend Chris McKay, played by Algee Smith.
The racy scene, however, quickly came to a halt after McKay choked Cassie without her consent.
Sweeney’s character became freaked out by the situation and immediately told her beau to never try the move again.
After taking MDMA at a carnival, Cassie hopped onto a carousel with fellow high schooler Daniel Dimarco, played by Keean Johnson, amid a fight with McKay.
While under the influence, she got turned on by the motions of the ride, leading her to climax in front of a crowd of onlookers.
Once she was finished, Cassie looked around in horror at what just occurred.
Cassie kicked off Season 2 with a hot and heavy makeout session with her new boyfriend, Nate, portrayed by Elordi.
In the scene, Cassie’s dress was pulled down as she and Nate got intimate in the bathroom.
Ultimately, the couple was interrupted when Maddy, Cassie’s best friend and Nate’s ex-girlfriend played by Alexa Demie, banged on the door, unaware of their relationship.
Cassie once again stripped down to nothing when Elordi’s character had an explicit fantasy about her.
At the time, Nate was rushed to the hospital unconscious after getting into a bloody fight Fezco, portrayed by the late actor Angus Cloud.
The duo was seen having intercourse, and Sweeney’s character was later shown lying on a bearskin rug sans clothes.
Cassie turned to OnlyFans to help pay for her wedding to Nate after realizing he couldn’t afford to pay for $60,000 worth of florals.
Throughout the episode, viewers watched as she posed topless and wore a variety of costumes — including a baseball hat and a baby outfit.
Additionally, she wrapped herself in an American flag while her housekeeper took photos of her.
Cassie’s most memorable look on the show was the leopard-print jumpsuit and matching gloves she wore in a dream about her rise to fame as an OnlyFans model.
In the dream, Cassie grew into a Godzilla-like monster, towering over a city and walking towards a building with a man inside pleasuring himself while watching a video of her on his computer.
When Cassie approached the man through the window she burst out of her bodysuit, exposing herself.
Elsewhere in the episode, she wore a barely-there leotard while jump-roping for her subscribers before later sucking on her toes while recording content.
In another risky episode, Cassie was seen sans clothes, as she covered herself with a yellow Python for a photo shoot.
She was noticeably struggling as the snake wrapped around her.
Sweeney’s character later changed into a pink lingerie set while posing alongside Anna Van Patten and Rosalía’s characters, Kitty and Magick.
Cassie’s X-rated scene with movie star Dylan Reid, portrayed by the son of Richard Gere and Carey Lowell, Homer Gere, was yet another wild storyline in the season.
In the episode, Cassie pursued the actor to try to regain her following after impulsively deleting her OnlyFans account.
She stripped down to nothing for a wild sex scene, which led to the duo breaking the bed.
After they were done, Cassie took Dylan’s phone and shared a video of themselves in bed, captioning it, “World’s greatest f–k @itsjustmecassie.” The post went viral overnight.
