She does

Morgan lazily glared over the page of her book and considered the brown beverage for a moment “Sure” She said and then took the cup from William’s hand.

He did his best effort to stop the grin from forming, he really did, but was simply unable to stop it completely, so instead he drank from his own coffee.

“Yug! What cheap brand is this?!” Morgan asked disgusted after drinking from the coffee.

William would had normally coward under the hateful glared that his sister was giving him, but not today, oh no.

It was time to test his grandpa’s notes “Calm down, Morgan”

Just like that all the fury left Morgan’s face and she leaned back on the couch “Sure, why not”

William blinked a few times and finally left out a sigh of fire relief. Morgan would had never in a million years have just calmed down like that. It had worked! His grandpa wasn’t insane and he had control over his sister!

Wait a moment... He had control over his sister.

It was better to confirm it, better start with something small “Sis, give me that book”

“Here you go” She said giving it to him.

Not bad, so ready to the next level “I never like you wearing so boring clothes, take them off”

“What ever you say” With that she got off the couch and began to strip. William really wished that he had told her to do it sensually and to put an a show, but before he could give another order Morgan was completely naked with only a necklace on.
