Your friend comes over to hang out and ya'll start fighting, your step-mom walks in and she thinks of an idea to help you make it up to him. She wants you to suck your friend's cock. You resist at first, but step-mommy knows best, and she tells you she will help you. She starts guiding you and then decides she wants to join in on the action a little bit too. I'm pretty sure this is a day your friend will never forget and may want to come to your house more often after this.
