Your doctor step-mom catches you masturbating at home! You know the rules mister. No masturbating without her. She's a doctor and she knows what's best for you and your health. It's just not right for you to be tugging on your dick for hours. Don't worry, step-mommy will take care of you with a nice handjob. But when that doesn't work, since you're so backed up, she has to resort to other more extreme measures. She tried not to show her step-son how much she enjoys sucking his dick and riding him reverse cowgirl and cowgirl, but it's too hard. In the end, she confides him that she needed this just as much as he did. They can be honest with their needs and help each other out going forward.
