One can imagine the comments which would have flown from the back bench boys when mom was seriously teaching. She would have been in her late twenties...when she taught and her ass must have attracted a lot of attention.My lust for my mother’s body was not gradual it happened all of a sudden, I still remember those scenes, it was my twelfth grade vacation. I remember the evening when I was busy watching tv and mom was getting ready for a function. My mom had called me twice and I reluctantly went. It was almost as big too. Thick, veiny and it looked delicious to a fledgeling sissy to me. Delicious and scary. I grasped it in one hand and quickly realized I might need two, but how could I hold the glass?Then it hit me: my mouth.I could use that to help, and I'm sure it would feel better than a struggled handjob. I began stroking, my hand gliding up and down his hardening shaft. His veins pulsed under my hand as his cock grew larger and larger. Eventually, the tip of his cock was in front. When his cock settled down and was not throbbing as much, I leaned back which brought it back in front of my face. I admired it for a few seconds and then reaching up grasped his shaft with one hand, putting the other hand back on his chest, to one of the nipples. I rolled, tugged, pulled and squeezed his nipples one after another as I brought his big cock up and slowly wiped it all over my face with my other hand. Each time it was at my lips, I licked the head and tasted the precum that was. All I knew was I was fucking my grandmother and I didn't want to stop.I let her arm go and grabbed her hips as I thrusted. I was no longer holding her down and I was shocked when she didn't fight to get away. She just lay there with her eyes closed, trying to hold back her grunting. I was really doing her now, and I felt my balls tightening, when suddenly she said something that nearly pushed me over the edge. She actually moaned the words, "You're gonna make me cum Johnny."My cock shot some.
