Gran

My Gran 61 is the quiet type, not use to talking much as my late grandfather always did the talking. She usually stayed quiet, after his death she moved in with her son my father and his family. Both my parents are lawyers like my late grandfather was and are busy most of the time. I'm the youngest of 3 at 21 trained as an electrician not smart enough for college like my siblings had been. So, when my parents were away it was just me and my gran, it was a Sunday afternoon I was out my parents were away, I came home earlier I'd said I would be. I heard a soft moaning sound on entering the house and thinking my gran was sick when to check on her. I opened her door without knocking and caught her naked on her bed masturbating herself. Both shocked at first, but my gran recovered first and saw a bulge in my pants. Asking me to show her my cock adding I'd seen her so it's only right she saw my cock. So, I dropped my pants, and my hard cock point straight at her. She had me come closer and started playing with my cock, I was enjoying her actions and so when she asked me to join her in her bed I did. She mounted me and rode me until I came inside her, after a short rest she had me go down on her and then mount her. In all we fucked three times, it caused me some problems at first. Every time I saw my gran bend over; I got a hard-on. But it wasn't the last time we fucked; every time my parents were away or out at a dinner we would fuck. I went from a virgin to a regular lover; my gran has trained me to satisfy her and now says I'm great lover. Which has boosted my confidence very much, I do date, but yet to fuck any of my dates. But I'm getting closer I think, but there is always gran.
