Breathlessly she responded, "Jim, I, I am your mother. There is no way in hell we can do this." Mom, we already are," I smirked as I leaned down and t...ok a nipple into my mouth as she placed a hand on my shoulder."Fuck, Jim, no. I tell you what you can kiss my breasts but that is it. And, you can only do it this one time only, understand." Yes mom," I eagerly agreed as I dove into the task at hand full force. My head bobbed from one boob to the other as I tweaked, pinched and pulled on her. They were of good size and amazingly firm.As mentioned above, she has a great figure.
