I'm just trying to be the best stepmom I can be. When I heard that my stepson was caught masturbating at school, I knew what I had to do. His "manly burdens" required a practical, hands-on solution, and I was going to make sure he got the full treatment. I'm on the freaking PTA board! So if he needs my body as his designated outlet for sexual release, he can have it. That's my job as his stepmom. I have to teach him how to control his cock. Don't worry, my husband won't find out. My pussy is only for him, but my stepson can fuck my ass.
