This started about 10 years back she was married then but now. She's my neighbour   who I had fancied for some time. I knew her husband rarely fucked her but she had a few young studs for one night stands.  It was a very hot summer when she went into her garden in only her sexy bra and panties my boxers did little to hide my hard cock. I joined her in the garden it wasn't long before we were both naked my cock was in her cunt fucking her. We both climaxed quickly then we went indoors for more sex play and fucking.  From then on it was one of two casual fucks gradually more frequent.   She is still very sexy her tits are small but still firm a little droopy but not saggy.  Her well used cunt is soft and silky still being tight . It has now become a regular relationship we share the same bed most nights for bedtime sex games before my cock is in her cunt to fuck her.  You could say she is now my mistress  as I still have several sexy casuals.
