Bi for Mommy's Boyfriend

Mommy's boyfriend is out drinking tonight and whenever he drinks it takes a long time to get his dick hard, that's where you come in....we will turn off the lights and you will hide in the closet, when it's time to suck his dick you will sneak out of the closet and do it for Step-Mommy. He won't even know it's not me, which is why you need to practice right now. We only have a few hours until he is home so we better hurry. I know you want to be a good boy for Step-Mommy and learn to suck cock perfectly. Now lets begin.
