The Swedish series Threesome, which debuted on the streaming service ViaPlay in the summer of 2021, follows a young couple named Siri (Matilda Källström) and David (Simon Lööf) who have been together since high school and, when we first meet them, have now hit that dreaded rut which sets in for nearly every couple. On a night out in their adopted home of London, they meet French art student Camille (Alma Jodorowsky, granddaughter of famed filmmaker Alejandro), a free spirited young woman who seems sexually appealing to both of them. After they get several drinks in, the three return to Camille's place where they have... you guessed it... a threesome! Siri awakens in the middle of the night to find David spooning with Camille, which she keeps to herself at first, but soon begins to become the dividing rod in their relationship and a sign for her that things aren't as good between them as she may have hoped. With school starting up again for David and him returning to Sweden for his education, things are only going to get more dicey in their relationship and they both need to open themselves up to the possibility that they just aren't meant to be together. While the titular threesome comes in the debut episode and is arguably the highlight of the entire series, Matilda Källström does go nude several more times throughout the course of the season, usually only baring her breasts, though there is a nice look at her butt later in the season! However, seeing her and Alma Jodorowsky topless and getting busy in the threesome is worth your time all by itself! This Threesome will make you wanna have a Onesome!
