Im so glad your mom went out to the store so we could be alone. I am your Aunt and its about time I tell you about the tradition between all good Aunts and Nephews. I need to be a good Aunt and help you widen your asshole. You need to start training at your age in case you turn gay as you get older. You need to be ready to take it up the ass at any time. So I am going to assign you butt plugs to wear. And you must wear them 24/7. You cannot take it out unless you ask my permission. Dont be ashamed we will never speak of this to anyone, its our little secret. And since I am willing to be a good Aunt and help you with stretching your asshole out, I want you to keep in mind I should get something out of this too. Not only is there a traditional 20% of your income deal in this for me but I want to be able to pleasure myself to the fact that I did this to you. Its so hot that I get to widen my nephews asshole and I want you to jerk off to the idea too. Of course you will have your ass stuffed while you cum and thank me out load. I want to hear you scream in ecstasy and thanking me for ruining your asshole. Lets go into the back bedroom before anyone gets home and I will supervise your first ass stuffed jerk off session while I play with myself.
