She was gentle. It felt good as I tried to relax as I knew I needed to do if getting fucked in the ass was to be more than a grim experience. She spen... quite some time 'fucking' me with first one finger, and the another, and two together. As she did, my penis, which wasn't very big to begin with, even when 'erect', had become very hard; and each time Tara guided a finger (deeper each time) into my throbbing butt-hole, clear liquid, pre-cum, started oozing out and down on the sheets below."How. She left the room and returned wearing a strap on dildo... it was about 7" long and not real thick and she informed me I was going to become a "real" woman and learn to suck cock! She threw a pillow onto the floor and commanded me to my knees. She started to rub the tip of the strap on around my lips and told me to kiss it and lick the tip which l did. Holding the back of my head so l couldn't pull back, she slowly pushed it past my lips and over my teeth into my mouth... at first it was. Then my son sent me a picture of his cock. Ok I am his mother, I may be prejudiced, but my son has a magnificent cock. This was a cock a girl could curl up to, or impale herself on to. Oh god what am I thinking? I am looking at a picture of my sons cock and loving it. I clearly understood that this was wrong. But wait a minute, how wrong is this really? I am just doing undercover work right? None of this counts because he is never, and I mean never going to find out that his mother is looking. I thought of thrusting my dick into him, as I knew he won’t mind that, and I followed suite. I started fucking his mouth, and he liked that, he adjusted his tongue movements as and when my dick was fully inside his mouth. He sometimes bit the tip of my dick, and I said “Ouch! Don’t do that!”He laughed and continued his job. He was pretty good at it, at such an age he was experienced enough to give me the finest of pleasures. Not that I didn’t have someone doing this to me before, but I would.
