Listening to mom

I was around 24 when this happened. I've always wanted to watch my mom masturbate. One morning I heard her in the guest room next to mine. I could clearly hear her vibrator going in and out of her. As quietly as possible I made my way to the wall and listened to her pleasure herself. I lowered my pants and joined in. I really wanted to walk in on her and lay beside her and just watch her cum. I felt happy that I could hear her. I heard the vibe in your pussy. I had seen it and had a perfect vision of the activity beside me. I heard her moaning as she came, around the same time as me. 10 years later I wished I would of at least "accidentally" walked in on her.
