Kate decides she can't work with Yelena any more. Madame Maureen launches an aggressive advertising campaign, prompting middle-aged punter Michael to worry his secret shame is about to be made public.

Mild-mannered student Kate has had enough of Yelena's domineering ways. The pair are now regular threesome partners, but while the punters are fine, Yelena is alarmingly over-enthusiastic when it comes to sadism. Even big Barry handles her with care; he recommends that if Michael ever indulges in any kinky stuff he must have a "safe" phrase to bring proceedings to a halt. His is: "Stop... Hammer-time!".

But love-sick Michael just wants to talk to Hayley, and even her special discount price can't tempt him to drop his trousers. Nevertheless, he tries to use some of her sexy tips to get his wife in the mood, but unfortunately, while the compliments go down well, being called a "horny little slut" doesn't - so it's back in the doghouse...

But Michael has bigger worries after Maureen unveils her new plan for world domination - a website, to be advertised on flyers stuck all round town. Hayley is all excited ("I could be famous!") but Kate and Yelena are woried, as both have reasons for staying anonymous. "They might see it at college" worries Kate, whereas Yelena's past may catch up with her: "They might see it in the Hague!". Kate is tempted to quit, but Maureen talks her round with promises to keep her off the flyers and the website, and to take her off threesomes duty.

Meanwhile, Yelena has a shock when Maureen joins her for the next session, in take-charge mood. And when Hayley's pop-up ad appears on Michael's computer, he has some serious explaining to do to Pippa...
