Swingers Sex Party (2007)

"Swingers Sex Party" plays out as an erotic drama built around exactly what the title suggests, with partner-swapping and group encounters driving the setup. Christine Nguyen takes the lead role here, and the single clip on the hub catches her fully nude in an explicit sex scene. It's just 1 scene total, short rather than feature-length, but it puts her bare on camera without cutting away.
