Break up with her Boyfriend

I had never been a fan of my sisters arrogant boyfriend, personally i always though of him as a bit of an asshole, but for some reason my sister absolutely loved him, but now she belonged to me, so it was only right they end it. i turn to my docile sister and say "I want you to call your boyfriend and break up with him". Almost immediately my sister replied in her monotone voice "As you wish my master". she goes to her room and picks up her phone and calls her boyfriend, i stand amazed still in my room that this is happening and i can clearly hear my sister speaking "Hello Henry, yes i don't love you anymore and i'm breaking up with you, please don't ever call me again". as i stood their in silence and aghast my sister walked back to my room and stood in front of me "task complete master" she said.

This was going to be awesome.
