'my appetite is much larger than my father's was, You both shall serve me tonight' leaving both of them surprised as they thought that you would only use one of them a night. Looking at their confused faces as they wait for you to pick which one to stick your cock into you inquire 'oh are you only used to fully satisfying your men without helping helping each other out?'

'yes master, I've practiced how to properly serve both nobility such as yourself and whoever else you wish so I can perfectly satisfy you on my own"Rubina assures while gazing greedily at you wanting you for herself much like how Alina is as well .'I was perfectly able to satisfy your father completely without any assistance before siring of either of his children' Alina brags.

'do either of you wish to go against my command and act without the other' you rhetorically ask as you sense some jealous within them.

'no master' they both respond nervously.
