Me and my wife have a great sex life, always trying new exciting ways together and alone but with no one else, we often tell each other our stories of how we masturbate when we are alone, ie in the car, shopping, beach, or garden. When we are out we are always touching each other up and finding somewhere to cum especially when people are around.
Anyway it gave me an idea, I've got this digital recorder so one Sunday morning when I know she likes to wank off I set the recorder up under the bed. When I returned a few hours later I couldn't wait to listen to it. When she went out later to see her friend I started to listen, after a while I heard her start to play with herself. I could hear her slight moans and this got my cock hard.
I got naked, lubed myself up and carried on listening, her moans got louder and I could hear her fingers slapping her wet pussy. Then I heard one of her vibrators start and to my surprise she started talking to herself saying things like get up my cunt, fuck me hard.
By this time I was wanking like hell, I had to stop myself a few times as I wanted to come when she did, she was now really going for it. She was saying things like up my arse and pussy you bastard! I know she likes doing this while sucking her long nipples.
All of a sudden she was screaming away going mad, her orgasm like most times went on and on. I was spunking all over myself by now cumming hard myself. I couldn't wait for her to come home when she did, I had to fuck her there and then. This set me up for weeks of masturbation.
