I watched my mother masturbate. We lived in a small house when I was around 12 and her vibrator was really loud. She liked to party so I could safely tiptoe to her door and nudge it open a crack without her noticing.
Her bed faced the door so it was a full on view and I saw everything. She would thrust her ass and whimper when she came and I had never seen ANYTHING so exciting. I’d try to make it back to my own room to masturbate but I came all over her door once.
I confessed to her about it many, many years later and that made me really horny, too.
