You have been steadily trained by your Stepaunt and have learned that you will be made into a breeder. She enters the room seeing you on your knees as you should be for her and she congrats you on that but she wants to give you something to indulge in as a reward for turning down woman who was into you. She pees in a glass and gives it to you. you are a good Stepnephew. she gets you to closely worship and tongue fuck her ass and to worship her breasts. She then teases you how you lost your virginity to that other woman but only truly wanted your Stepaunt and so she says she is going to fuck your ass again, but you're not allowed to cum until she says. As she fucks you it becomes more difficult not to cum but you withhold yourself. She then says that you are going to breed her and so she rides you until you cum inside of her. She gets you to eat the creampie out of her pussy and she is pleased with your performance today.
