I am a married woman, but twice a week, my lover visits me for a moment of debauchery. Until one day, right in the middle of a cunnilingus, my husband pushes the door... and there I am, fucking with my lover and my husband at the same time! The door slams, the steps on the stairs, the engine starting, the gravel crunching under the tires and the silence. The silence as a signal: my three hours of adultery can begin. Three little hours, twice a week. Tuesday and Thursday, between 2:30 p.m. and 5:30 p.m. Never before, never after, never...
