About twenty minutes later, I woke up again and watched my mother beside me breathing sounds, and I began to feel distracted again.I tentatively put my palm on my mother's waist. My mother didn't move and her breathing was nothing unusual. I became bolder and moved my palms down, covering my buttocks with my palms, and gently stroked them.My mother's butt is very fat, and it feels very elastic. After stroking it for about half a minute, I started to move my hand toward my mother's waist. When my hand was pressed against my mother's underwear, I stopped for a moment, then suddenly reached into my mother's cotton underwear. My fingers swam directly to my mother's smooth and soft buttocks, and stayed there.
