I then began to stroke myself off, slowly sliding my hand back and forth, over and over as...I kept my grip firmly around the length of my shaft and stroked myself off in front of her."Look upon me as you jerk yourself off, Adam. I want you to see me as your sexual desire whom you wish to please. My beauty. Imagine me naked before you, fucking me in positions of all kinds. My hands, gripped upon your cock and stroking it for you. My lips. Every time you back-answer or refuse to do as you are asked your mother is to note it down.

I said okay and he got us both a bottle of beer. We sat and drank our beers and made small talk for a few.
