Do you want my ass, Daddy?

from DarkLust

You decide to be nice and take your stepdaughter's clean laundry upstairs to her room in the laundry basket. As you approach her door, you hear a soft moan, followed by a much louder scream. You panic slightly and open the door. Lying before you, completely naked except for her stockings, is her bottom in the air and her head upside down on her bed. A vibrator is dangling from her buttocks.
