My Girlfriend's mother

I once fucked my girlfriend's mother!! Okay, here's how it happened:
I was about 19 at the time, and my girlfriend was 14. We'd been going out for a couple of months, and I went round to her house in the afternoon (as I often did) to wait for her to come home from school.
It was a very hot summer's day, and I was only wearing a t-shirt and a pair of swimming trunks/shorts. Her mother made me a c up of tea as usual. Then we sat down and talked.
Somehow the conversation got on to her saying that her daughter was quite shy and naïve, and she hoped that I would treat her right. Then she said that she wanted to check what I had, to make sure that I didn't hurt her daughter! Before I could realise what was happening, she had pulled down my shorts to reveal my cock. As she took it in her hands, and looked at it, not surprisingly it began to grow upright! Telling me she wanted to check my technique, so that she could advise her daughter, she quickly pulled off her blouse and bra - and her skirt and panties. Then she lowered her pussy onto my cock!
I remember her big bouncy tits and her hairy pussy. It didn't take me long to cum inside her! Then we stood up, and got dressed.
Neither of us ever mentioned the incident again - I wonder if she did advise her daughter on anything!!
