I've given you, my stepson, a list of chores to complete while I'm gone running errands. Instead of working on that list, you end up in my room working your own cock using my silky panties. You're sprawled out onto your father and my bed, when I walk in, having forgotten my purse. You're exposed and embarrassed but relax as I move in slowly toward the bed. I'm flattered and honestly a little turned on by your attraction to me. Your father doesn't fuck me anymore...I don't think he can keep up with me because of my age. Say, I don't mind keeping this a secret if you want to take this a bit further. If you like those panties, I know you'll love the ones I'm wearing...especially when you pull them to the side and slip your nice long dick into my eager unsexed slit. We fuck every way we can as I climax repeatedly. God, it's been WEEKS since I've had sex and I just need my tight pussy filled with your throbbing erection! After I've been fucked properly, I work your rod with my hands and big MILF tits until you shoot your big load all over them. Right as we finish, we hear your father's voice boom from downstairs, "Hey guys, I'm home!" Maybe this won't be our secret after all...
