Like most modern couples, Shan and Mark struggle to fit sex into their busy lives along with family, friends and work. Snatching a few precious moments alone, they start to have sex but are interrupted by guests arriving early. To their surprise, Shan and Mark realise that stopping before they came actually heightened their pleasure, increasing their feelings of lust for each other. Keen to explore the idea of delayed satisfaction, the couple set a date in the diary, allowing them to climax at the weekend - but not before.
