My granny is in good shape and does not look her age. And granny and I have fun together and we talk alot. Well so I am there doing my school work and...watching TV. Granny takes off to visit the neighbor. For some reason I decided to go into granny's attic to look for something, more to snoop. I find this box hidden behind some crap with three VHS tapes and some DVDs in it. They are unmarked so I decide to see what is on them. I figure family stuff. I go back to my room that has an old school TV. My heart started to pound and I started to get flushed at the thought of what was to come. While we ate it was a little tense both of us thinking maybe we had said too much so after when we sat down to watch TV I decided I would break the tension. I sat down next to him on his right side curled my feet underneath me put one arm around his neck looked into his eyes and said, I'm sorry Mr C I know that I can be a very naughty young woman and how much I probably deserve to be spanked so if you. As my hands spread his butt cheeks further apart, I managed to get one finger (covered with spit) into the tip of his asshole. I quietly said: "Let me in there." He struggled and his torso fell foward, his ass now high in the air. I sat up and began pleasuring him with my finger and mouth, saying "Comon Bob, let it go. I want to eat you. When you feel my finger slide in, tighten your butt. Use those muscles. Grab that finger. Feel it slide in and out." I pulled at the jock strap on either side. So I got up & had a look I'm thinking nice knickers, I turned round & Alice was standing behind me, she said do u like my knickers, yes I said she handed me my drink, then said I know what u & Shiela do, she told me one day when I ask why u call at funny times,I said she did, yes she said I know u are having sex with her, she didn't tell u tell me u are having me on, its not true, well she says its is, I don't blame u, us older women like a bit of fun too u know, I looked at her with my mouth.
