At an art auction Pete meets 50-year old Ros,who is attractive,wealthy and urbane as well as being sex-mad,foul-mouthed and married to the glowering Duncan,though she insists that theirs is an open marriage. Duncan's disapproval,a disastrous visit to his parents with Ros and the feeling that he is her kept man drive Pete away from Ros and back to the forgiving Chloe. He tells her that Ros is his auntie and asks her to his birthday party. Here his lies come back to bite him as his distraught 'auntie' turns up demanding sex. Furthermore the girl who jumps out of his cake is Anna, who has just heard him betray a confidence she told him.
