Naturally big girl Stacey has eaten far too much over Christmas and is desperate to lose weight. She joins a fitness class at her local gym, where she meets a dreamboat instructor Matt, who can't keep his eyes or his hands off her. After her first lesson, he invites her to the staff swimming pool and offers her a compulsory rub down afterwards. Stacey can't believe her luck, nor the fact that he's happy to indulge her other desperate wish - to have a baby!
