Mistaking an address, a naive couple stumbles into a swinger's party. As they try to leave, curiosity and arousal keep them rooted. The wife, in a red dress, feels eyes on her curves as her husband, in a crisp shirt, watches her squirm. They're encouraged to join the orgy, the room filled with moans and the scent of sex. Hesitantly, they strip, the wife's breasts heaving as she's sandwiched between two strangers, her husband watching, hard and conflicted.
