He Hypnotizes them, Makes Brooke undress her mom and caresses Meredith's body.

He looks at both mother and daughter, he started planning something, until he got an idea.

"When I snap my fingers you two will wake up, but you'll be in a hypnotic trance", Jack said.

He snaps his fingers, all of a sudden both Meredith and Brooke sat up on the couch, they each had blank looks on their faces, Jack was smiling at both of them.

"Meredith, Brooke, you two are in a hypnotic trance, you'll hear only my voice and obey me, do you two understand?", Jack asked.

"Yes, Master I understand", Meredith answered in a monotone voice.

"Yes, master I understand", Brooke answered in a monotone voice.

"Brooke, I want you to undress your mom, and caress her body, Meredith, I want you to sit still and don't move, do you understand?", Jack Asked.

"Yes, Master We Understand", Meredith and Brooke answered in monotone unison.

Brooke looked at her mom, Meredith looked at her daughter, Brooke started slowly unbutton Meredith's blouse, she took it off of her mom's body, and dropped it on the floor, she started caressing her mom's thighs, Meredith didn't react to her daughter touching her, Brooke reached around her mom's body, she unhooked her mom's bra, she started stroking her mom's back, softly, While Jack was watching them.
