My Gran

Long Story Short. I had to live with my Gran Beryl, mainly because I was at university. But also my grandfather had passed away last year and she was alone. Gran is in her middle sixties and is an active woman. She is 5'7" and a little overweight and I'm 5'9" little overweight with glasses. At 21 I was still a virgin and shy around girls, my Gran kept trying to build up my esteem. Then she caught me masturbating and she just took over doing it from me. I was shocked at first, but soon was enjoying it a lot, I came and it landed on her chin. She told me anytime I wanted to masturbate she would help, later that Saturday she was in her garden kneeing weeding and I got horny watching her. So I walked up and felt her ass and she turned around and said Not here. She got up and led me to her garden shed, once inside she told to drop my pants. First she started to play with my cock, then she stopped and took off her top and bra. Then back to stroking my cock, she started to suck it to lube a bit and I blew in her mouth. I expected her to cross as I didn't warn her, but she swallowed it and kept on stroking to keep hard. Once I was firm again, she lifted her skirt and pushing her panties aside lowered herself onto me and rode until I came inside her. We have sex anytime I want and last month my mother Kay 46 her daughter came for weeks visit. I thought no sex while she was here, but our first dinner together Beryl told Kay I was a great fuck. I almost fainted from the shock, my mother Kay answered That's good, I'll try him out tonight. Kay had asked Beryl to teach me about sex and as her and my father are in the middle of their divorce. She wanted to test me out and if I was good. She would move back with Beryl after the divorce and they would share me. I had sex with the both of them till returned home, she expects to be back in a month or so.
