It don’t mean a thing if it ain’t got that swing! And these luscious ladies mean business, because sometimes one partner just isn’t enough to get one’s interest rising. Speaking of rising, you’ll have one stand-up stiffy when you see Lindsay Lohan and Lily Labeau get it on during The Canyons' freaky foursome. Elizabeth Olsen doffs het top during an orgy in Martha Marcy May Marlene, Toni Collette’s cans are out during some wham-bam-thank-you-glam group sex in Velvet Goldmine, and Mimi Rogers and Stephanie Menuez switch partners (including an epically-mulleted David Duchovny) in The Rapture. Krista Morin and her mams host a swingin’ house party on an episode of Sex/Life, Hannah Arterton and Rea Mole have a lovely naked snuggle in bed with two guys in Amorous, plus more terrific team ups with Amber Heard, Melissa Barrera, and Lady Gaga, and more! Not the mention one of the many Sense8 orgies that’ll have you wishing you could join in on the fun!
