Katherine

In an act that surprised both girls, you suddenly grab Katherine's hand and pull her towards you.

"What the hell?!" Joanna shouts at you, bewildered by what you just did.

"I'll be honest she has treated me better in the past than you ever did" you reply to her, as you walk away with Katherine gripping your arm. Although you feel awfully disturbed by the sheer silence she is emanating in response to this. Then it hit you.... right in the balls. She snuck right behind the both of you and decided to uppercut you both in the genitals. Both of you drop to the ground in pain. You grip onto your balls, massaging them in an attempt to relieve the pain, but Katherine's suffering was beginning

Katherine was kicked by Joanna in the head right after she dropped down to grab her pussy. Joanna didn't let up after that though, as Katherine was lying face down she continued to kick her womanhood hard enough that her entire body was inching forward after every strike. Katherine was able to flip herself over to give her a chance to grab her pussy in an attempt to protect it, but Joanna wasn't having it. She began punching Katherine in the hands and then on the crotch giving special attention to hit her love nub with a knuckle.

"You bitch! I know he only picked you because of this!" Joanna shouts, right before she bites onto Katherine's pussy, sinking her teeth in Katherine's most sensitive areas.

Katherine's howling from the brutal attack by Joanna on her pussy is enough to raise you to your senses, and the pain has subsided enough for you to act.
