I've had a fetish for women's style sneakers from back before I could remember. As a child, I would masturbate using my sister's sneakers whenever I got the chance. I couldn't figure out how to tell my wife, so I sort of tricked her into it.
She was very pregnant with our second child. Child number one was down for a nap. It was Saturday, and I was making her breakfast as she lounged and watched TV. I had given up my recliner to her. The doctor said it was good for her to get her feet up, however with her out of whack center of gravity, it was very difficult for her to get out of the other chairs in the room. The recliner came with its own 'ejection handle.'
So there she is sitting in the recliner sipping her coffee. She was dressed in the least sexy outfit a woman could wear, but very typical for a pregnant woman: a sweatshirt, running pants and sneakers. I decided to kneel before her and massage her calves. She loves that and it was also good for her health to get the blood moving out of her legs. This put her feet sticking out over the footrest about penis level.
It didn't take me long to get hard, and I 'allowed' my penis to slip out of my pajamas. I pushed it against the soles of her sneakers intending just to hump them in the hopes of getting something out of it. She decided to bat it around with her toes, and then sort of trapped it under the ball of her foot, and peddled it back and forth between the sneakers. I looked at her as she stared at what she was doing, smiling and biting her lower lip in a coy gesture.
She squealed with joy when I came. She likes the idea about being able to 'make' me cum. Later that day we went out and bought several pairs of sneakers in various stores.
Since then, we experimented with several variations with me on the floor and her on the bed and in chairs facing each other. My wife has fallen in love with masturbating me this way. It's quick and easy for her and she gets to look at my whole body as she does it. She likes the way I react, and the look on my face when I cum.
