She ignores you and goes back to changing

I was in a world of my own for a second there when I heard my mother's voice again. This snapped me out of it.

"Thanks mister, but really, I've got this," came my mother's bubbly dismissal. She stopped thinking so hard, and turned back around. She was now none the wiser to my presence.

"Er...." I stood there quietly. Wondering if I should move or say something more. She acted if I was already gone.

Her focus was all on her clothes.

Adjusting the towel around my midsection, I swallowed the saliva that was edging the corners of my mouth. I couldn't seem to pull my focus from my mother's jiggling ass. Her exertions were proving comical and desirous.

I had a wicked thought.

Still eyeing my mother, I willed my soft cock to life underneath my towel.

Seeing the thick noticeable bulge, I was curious if my mother would say anything. I was even willing to take it a step further. How far could I play this?
