Visiting the incestuous family

When Karyn returned to Jon's house the next day, she was surprised to be greeted at the door by Zoe. The teenage goth girl smiled at Karyn as she arrived giving her more than a little surprise.
"Oh hi Karyn," she said with a flirty wink. "Here to see my stud brother?" she asked.
Karyn had to take a double take, Zoe seemed a little... different, glowing as she led her to Jon's room taking the opportunity to jump into her brother's lap as Karyn entered.
Karyn was rewarded for following by watching brother and sister make out passionately.
