step-Son, you were made to be our cum slut! It's your birthday and now you're ready to be our cum slut. Me and your step-dad are going to train you. Of course we don't want to throw you in to gang bangs before we train you. DON'T WORRY!! Your step-father has just filled my pussy with cum, and I want you to eat it out of my pussy. You'll enjoy it, it's a treat. You will eventually take it from the source, but for now... eat.
