I'm your step-mom. I walk in on you doing the most embarrassing thing ever ... masturbating - with MY leggings! Instead of being disgusted, I'm flattered. I am a woman, after all, and I want to be desired. You can really cum just from thinking about my ass in my leggings? Well, why don't you jerk off to the real thing? I turn around and show you my ass in my leggings while encouraging you to jerk off. I know it's wrong - we both do - but we don't care. When you finish, I tell you to come find me if you ever get the urge again. I can always help!
