I like to sleep nude.
I don't do it too often because it causes me to have erotic dreams. They are almost always about the same thing, the girl next door. She's not really a girl, but rather a mature and beautiful woman.
The dreams vary, but usually run like this;
I am lying in bed on my left side having just awakened. She is lying tummy down, with her face turned away from me, still asleep. We are both nude. It is early summer and only a light sheet protects us from the gentle breeze of the ceiling fan. Without awakening her I throw the sheet back and began to caress her back with my right hand. Across her shoulders, down her back to her creamy buttocks, my erection growing with each stroke.
