IFC Films released the first trailer for the R-rated Jason Sudekis comedy “Sleeping With Other People” on Thursday, June 25, according to TheWrap.

In the film, Sudeikis plays Jake, a serial cheater, who reconnects with former flame Lainey (Alison Brie) at a sex addicts support group. As they have both just gotten out of disasterous relationships, they agree to remain friends and establish a safe word if the sexual tension becomes a problem.

Lainey suggests they use avocado, but Jake says it’s “too sexual.” “You gotta see the way I eat an avocado,” he says. “You’re gonna be like, ‘That’s nice. Do that to me.'”

The film also stars Amanda Peet, Adam Scott and Jason Mantzoukas. Will Ferrell and Adam McKay served as producers on the film under their new Gloria Sanchez Productions banner.

“Sleeping With Other People” opens in theaters September 11.
