All Comments on 'The Commencement'

I caught me step grandmother riding a dildo when I was 15. At first she was mad at me and accused me of spying on her, but I wasn't. The next day she asked if I enjoyed what I'd seen the day before and I said yes. She asked me to keep it a secret and let me watch her again and asked me to rim her asshole while she fucked her dildo. I did, and we did each time I went to visit her. I never fucked her, but she sucked me off several imes and I ate her pussy and ass all the time.
