My fembom has herself a male dom and some of his rules affecting me and her

Last time we had playtime my femdom told me her ass belongs to her sir and told me she asked if he okay when she wants me to plaesure her like with my mouth of fingers or sex.

First i didnt notice but no a day later i feel uncomfy with this direction it.s heading, like i dont think her other d/s realtion should affect the d/s realtion between her and me how can i communicate this to her in a nice way?

ldc if she needs to tell him after the playtime that i pleasured her but, i dont want to be restricted by her dom, in my and her d/s realtion in anyway she should like have the free choice what she want.s to do without worrying about her dom all the time while being my mommy.

Sorry for my bad english ><
