She makes me feel so inadequate.

The other day, my wife surprised me when she let me let me play with her tits while laying in bed late in the morning. I got to suck on them, play with her nipples while she laid there letting me do what I wanted which is unusual. I got to play with her feet which she enjoys and really excites me. I went down on her removing her panties and licking her with everything I had and feeling pretty good about my enthusiasm. Mostly, she laid there seeming to enjoy what I was doing but not reacting all that much. I got super hard. couldn't wait any longer and tried to crawl between her legs to slide my penis inside her. She smiled and pushed me away, saying, "that was nice but don't be silly, you know that little thing does nothing for me" and got up out bed.
