Just then, Jon heard the garage door open. "Oh, your dad must be home," Linda said, reluctantly pulling her pants back over her stiff member.
"Thank God," Jon thought to himself. The whole experience up to this point had been somewhere between surreal and unbearably disgusting. Jon followed his mother downstairs to greet his father. As Mark Madison walked in, Linda gave him a quick hug and a quick kiss. However, Jon noticed, she had an odd grimace after the kiss, as if she hadn't enjoyed it. Then Mark turned to his son. Jon gasped; he had never noticed how handsome his father was! Just looking at his manly face and angular body made Jon wet down low. Jon imagined kissing his father and having him enter...
Jon shook his head. Mark had passed him to go get changed. Jon was in shock: he had just fantasized about his own father! Then Jon remembered the last part of the wish: I wish that for the duration of the swap our genitals will react to the same stimulations that they did when on their original bodies! Jon's pussy was reacting to the man that it used to be attracted to!
