Their friends can't believe it as they watch Lou-ann, laughing all the way..Undress her little step-sister and begin whipping her violently while she is chained to the computer desk..You can here and see the severness of the whipping...and the big step-sister just keeps laughing as she whips her step-sister harder and harder and her sisters back gets redder and redder..She wasn't expecting her step-sister to hit for real!!
