You were feeling a bit under the weather so I told you to take some medicine. I come to your room to check up on you and to tell you that I'm leaving for work and should be home about the same time as your step-dad. As I open the door I see you standing there with a super hard erection. What are you doing? It seems that rather than taking the pill in the blue box you took the blue pill. That's your step-dad's ed medicine. You have to make that erection go away or we'll have to go the the emergency room. Have you tried jerking off? What are we going to do? I can't leave you here like that. When your step-dad takes it I just fuck him and he gets satisfied and the erection goes away but, I can't very well do that with My step-son. I must say though. Your cock is impressive. you definitely didn't inherit that from your step-father. Maybe I can help. How good are you at keeping secrets? Maybe I could use My mouth to get you some relief but, if your step-dad finds out he'll leave Me and we've only been married for six months. Can you keep a secret? I reach out to grab your hard cock and lower My self, all the while thinking... what a great fucking cock. Too bad you're My step-son. As I take your cock into My mouth something starts to come over Me. I'm getting so hot on My knees sucking My step-son's big cock. You don't seem to be getting any relief from My efforts and secretly that's ok wth Me as I really want your big fuckstick inside Me. I tell you to get on the bed. I believe that My sweet, magical pussy will get you satisfied. It'll cure anything. You lay on the bed and I have another taste before I remove My panties and prepare to mount you. I'm so horny at this point that I don't even bother to remove My work dress or crotchless pantyhose. I reach back and guide your cock into Me. Slowly at first I begin to fuck you. I gradually build the pace as I am truly enjoying your cock. After several minutes of fucking your big dick, I know that My MILF pussy has worked it's magic and you are about to cum. I want your hot jizz all over My ass in shiny black pantyhose. As soon as the tip of your cock is freed from My magical pussy, you start ejaculating a massive load. We can defintely never tell anyone about this but, we can surely do it again.
