In some historical cases the royal kids were fed milk from mothers who were selected and had to part with their own kids.
>mom is youthful and has huge breasts
>word reaches prince and he summons you both
>he's in his late teens as old as you
>he explains that he needs to feed on breastmilk for his 'illness' and only your mom can help him
>mom feels sorry for him and agrees to breastfeed him daily while he orders you to be his servant
>prince is a bully, he picks on you and openly milks your moms huge tits dry in front of you
>over a few weeks you notice you become weaker while he becomes physically stronger and more agressive towards you both
>the bullying gets worse and your mom gets worried
>one night you hear your mom slip out of her room and head into the prince's chambers
>you follow her only to find the door locked closed
>eventually you hear the telltale sounds of her moans and the bed rocking
>you hear the prince agressively suckling on her breasts sucking every last drop
>finally you heard her orgasm as the prince deposits his bull seed into her warm depths while you dribble your weak sperm over your fingers
