Not quite

You look down at Grace's come spattered face, feeling as powerful as you've felt in years. You step back from her, tucking your cock away and doing up your pants as she slowly gets to her feet, her eyes never leaving yours. You note that her nipples are bulging the fabric of her top, and that her pale skin is flushed with excitement.

"You aren't finished missy!" you tell her. "You got your sister out of being punished, but you still have punishment to take." She looks at you with wide eyed shock, her chin trembling.

"But...you...but you said...." she stammers, fighting tears.

"I said I wouldn't punish your sister. You still have some coming."

"But...but...I sucked your cock!" she wails

"To get your sister off the hook. Now turn around and bend over. Put your hands on the bed," you order, picking up a hand mirror from your dresser and smiling cruelly at her.
