I previously submitted a story here about my mom in law. I'd been masturbating in the bathroom while it was just the two of us home alone and i was sensing that she had been listening to me from outside of the door. I really hadn't been making any attempts to be quiet while doing it.

It progressed to me pulling my cock out one day when she was sitting behid me in the computer room going through her files. The thought that she was so close to my hard cock was blowing my mind. All I wanted was for her to spin my chair around and go down hard on my dick.

Well today we are home alone again and im thinking of how I can take the next step. She just mentioned she needs to head out to the doctor tomorrow which is 40 mins away from home so i offered to drive her. She seems happy with the thought. What can I do?? I'm not sure what angle to take. Get her talking about something sexual somehow?? Get my cock hard in the car and let her see the bulge?? I'm loving the teasing more than anything. I just know she hasn't had good dick in a while and it would be on her mind. The thought of me pulling off to the side of the road and having her blow me off is top of my list right now. She really is one of those loving, caring Moms who would do whats necessary for her Family. I reckon she would suck the dick like a pro. I just want her to service me. Is that too much to ask?? She'd be doing us both a favor.
