Caught wanking by my nan

Note : This story is completely fictional!

I'd popped uptoy room for a quick wank after walking in on my nan naked, she had the most perfect boobs I'd ever seen her nipples were huge and her pussy was totally bald she was in her late fourties and I was 19 year old virgin at the time so of course my hormonal cock was hard instantly so i turned around and ran to my bedroom.

I thought that i would try what my nan does so i shaved of crotch bald and it looked magnificent, i layed on my bed after cleaning it up with my cock still hard and wanked. My nan had obviously seen or heard me when I ran upstairs as she came to see what the problem was and if I was alright, I however didnt hear her open the door and she walked right in and began to talk before realising what I was doing and sitting on my bed looking at me in an astonished manner.

She asked me what the hell I was doing so I told her everything from seeing her naked to shaving my balls to right this very moment, then she asked one question I never thought she would ask me did I want a blow job. At first I was shocked but then i realised that i could end up having sex with her so i sed yes please nan but only if I can lick your pussy, she took her time before agreeing to let me see her pussy again I let her touch my cock for the first time at the same time I let my tongue wander and pass over her slit before forcing it in with one push I started to tongue fuck her I then added a finger to help me make her orgasm. However at the very moment she started to cum she bit the tip of my cock and made me blow my load all over her face. She licked it all and drank it down.

I turned her around and moved her thong across and positioned my head at the entrance hoping that if she wanted it as much as I wanted to loose my virginity that she would push down and take my cock in her, but to my suprise she gently lowered herslef onto my cock because she didnt want to hurt herself. We continued to shag for well over an hour before the phone rang - it was my mum letting us know that she would be home in about 15 minutes which didnt leave us with much time to shower and get dressed but somehow we managed it.
From then on we had sex whenever it was possible it was always as good as the first time but it got riskier and raunchier every time.
