At the moment, it was hard to think about homework, because when mom had gotten up and walked to the kitchen I'd been given a nice view of her pert ass in the gray shorts, and all I could think about was the absence of panties under them, and the lack of any panty line. Mom's ass was perfect -- firm, round, and sculpted. I knew she did squats and other exercises at the gym to keep it in shape, and whatever she did, it worked.

The sight didn't help my hard on, though. If I stood up and followed her to the kitchen to help it would be impossible...
