Bedtime with Mummy...50

Your Daddy married Claire when you were only two years old, so you've always considered her your Mummy. You still call your father 'Daddy' even now you're eighteen, so it's perfectly natural to call her 'Mummy'. To call her 'Stepmummy' just sounds silly. She adored you from the start, and doted on you, and spoiled you rotten, and mollycoddled you, and is delighted that you've always been her 'Mummy's Boy'. Even now, when you set off for college, she adjusts your uniform and straightens your tie and gives you your packed lunch. Daddy's away on business, as he often is these days. You're asleep in bed when you have a terrible nightmare. Both parties are aware that any sexual activity must be with mutual consent.
