On the drive back Grace was telling me that my sister said I had a nice size cock and that I came a lot. I liked that. All the while she was rubbing my cock through my pants causing a precum stain on the front. After I got out of the car I tried to conceal my erection as best I could. Thank god it was.

Just to make sure everything works. He's not a professional like those other two." Gosh, I suppose you're right. We would probably need to do it several times; just to get him at ease."

Mine is why I’m here today. ‘Cos I’ve never told anyone about it. No one. I talk to my mum, and I tell her just about everything, but I’ve never told her this. I’m not ashamed of it, or shy – but I do worry about what she would think of me.
