Between Your Legs (1999)

Victoria Abril isn’t just walking her dog every morning in Between Your Legs (1999)-- she uses her daily routine to cheat on her husband with a series of random horndogs. Then she meets phone freak Javier Bardem at a meeting for sex addicts, and the two discover they have a lot in common, starting with a tendency to jump into bed. Then things get complicated as Javier finds out his phone-sex conversations are being recorded, which helps Victoria’s policeman husband discover their affair while he’s investigating a murder.  But the mystery we're really conceded with is what's between Javier's legs--too bad there's a woman's head in the way practicing her sword-swallowing routine.
