Emma had played "house" with her older step brother Benjamin , when her and mum just moved in but now he said he was too old for it. Emma loved the feeling of dominance over babying the older brother and she wouldn't be denied . It was easy to sleep some diuretics into his pre-bed time milk . Then mum when prevented him from any late drinks , Emma collected her own wee and poured it in his bed while he slept. Out of ideas it was easy to manipulate mum to put him in diapers.
