I figure it's time you knew that I've been fucking your best friend. You know your dad is kind of getting up there in years and even though I love him, he doesn't satisfy my needs. Your best friend offered his cock to me and I took it, again and again. Oh now don't get jealous. I can't fuck you, you're my step son. Maybe I can at least help you get off without touching your dick. Go ahead and get your dick out for me. I want to see if it's as big as your friend's. You can rub it for me. That’s it, rub the tip gently. Show me how you stroke it. I'll even show you my mature body while you rub yourself to climax. This is a bonding moment isn't it? I hope your dad doesn't come home from work early and catch us like this. It's not bad because I'm not touching you. Are you ready to cum for me? That wasn't a very big cum load, you poor thing. I may have to save some of your friend's cum in my pussy next time I fuck him so I can show you what a real cum load looks like.
