Several years ago my wife began pinching and sucking my nipples during s**.
As the years have passed I have found that it is just about my favorite part of having s**.
Even when I m********* I pinch and tug at my nipples imagining all kinds of things that might also happen to me.
One of my favorite things is when she is under me sucking on my nipples and bends her knee so that I can straddle her leg and push my bottom against her thigh over and over.
I can not tell you the things I imagine are or could be happening to me during those times.
There is no telling what I might be willing to do during those erotic times of desire.
