You couldn’t really blame me. I was an 18 year old with raging hormones back then where my dick had a mind of its own. However I knew I wouldn’t d... anything stupid because she was my granny, and she grieving her dead husband.We ate in silence, or rather I ate in silence, while granny aimlessly ran the fingers all over the rice and dal. “Granny,” I said, “if you eat your food, I’ll bring out the photo album which mom has hidden”She looked up at me immediately, her demeanor changing almost. “Baby, Monica said that you should try to have orgasm’s that help relieve the buildup. She said that some porn videos might help you learn how to stimulate yourself. I have one here on my tablet. Why don’t you see if you can try to do what the girl does to see if it will help you?” Ron asked as Elly looked at what he had handed her.Ron watched as Elly headed toward her bedroom. He already began to envision her on her bed holding the tablet and rubbing her pussy as she learned how to squirt.. I watched as her fingers popped the top two buttons."One more, " I said."No, please, Dear." she begged, "it'll show too much and these are people we see all the time." Do it," I demanded.That was better, the last button done up was below her bust line. She slipped her leather coat on and we walked the few hundred yards to our friend's house.Getting near midnight and lots of drinks later, I was dancing with our hostess, Katie, whom I know since school days; and, although we had never got it. I can feel my panties soaking through; it is all I can do to concentrate. Finally the day ends, before I can even think about heading home I have to stop in the bathroom and give myself some relief or who knows what I might end up doing. I grab my belongings and head for the bathroom. Just as I approach the doors, the cleaning staff steps in front of me and sweetly tells me they will be closed for half an hour. So much for that idea. My frustration and arousal increasing, I scurry off to my car.
