my wifes vibrator

I love watching my wife tease and please herself with a vibrator. First time ever we were fooling around with a tiny vibrating toothbrush thing, we did that from time to time, then one day i bought a bullet vibrator, cheap one but it broke. Then a bought this bullet that had an assortment of sleeves. I inserted it one night, slowly and pushed it to her g-spot, she got so wet, and then we made love. I can blow just watching her play with it. It has an attachment that turns my cock into a vibrator but it just vibrates it so bad it goes numb and I find that hard to control.
