Is It Normal For A Boy To See His Mom Nude? Part 3

This is the continuation of my confession.

The process of her sleeping casually continued and it became a normal thing for me. Now I too started to sleep only in boxers with nothing inside.
Yesterday when I saw her pussy again well exposed and inviting, my cock went wild. I thought of doing something naughty and an exciting idea striked my mind. I rolled her to one side and spooned her. I hugged her tight, my arms pressing her boobs and my one leg over her.
I lifted her maxi till her waist and started poking my boxer covered cock on her bare pussy.
I just felt that she might also be enjoying it as I heard her a bit slow and deep breaths.
My cock was really enjoying it and I was feeling like I was in heaven.
Later I decided to tease her a bit and so I rolled to the other side. She might have been irritated by my actions as after a few minutes she hugged me from behind.
I was acting as if I was asleep. Later she started to move her fingers around my chest and stomach area.
After a few seconds, while carecassing, her hand slipped and she touched my cock. Due to all these incidents, my cock became rock hard and stiff. She felt my cock for 9-10sec over the boxer and then removed her hand and gave a smile.
Then she rolled over and slept.
I too had a busy day so slept within a few minutes.
