Last year when I was a senior in high school we had a half day off from school. They let everyone go home at noon because all the teachers in the school were in a meeting the rest of the day.
When I got home the house was quiet. I saw my mom's car outside so I knew she was somewhere around the house. I walked into my room and put my stuff away, then I walked down the hall towards the bathroom. My parents bedroom door was closed but not all the way. There was a little crack of an opening. I figured she was taking a nap or something. When I neared the door I could hear a slight humming sound coming from her room. I peeked into the room and saw my mom spread eagle on the bed, naked, using a vibrator on her pussy! Wow! I had seen my mom naked when I was little, but never after I was about 6 years old. My eyes were fixed on her super hairy pussy as she guided the vibrator in and out of her pussy and over her clit. I don't think I've ever seen a hairier pussy in my life, not even in pictures. It was thick and black. I looked at her tits which were nice and full, and her big brown nipples.
She was laying down with her head on the pillow and her eyes were closed as she concentrated on the feeling she was giving herself. Occasionally, she would lay the vibe down and use both hands to pull her pussy apart and she would rub her clit and then slide several fingers back inside her pussy. Then she would go back to the vibrator.
I got hard as hell watching her. I was rubbing my dick through my pants as I watched. Now and then she would pull her legs apart and raise them pulling her knees back towards her head, and she would almnost violently push the vibe in and out of her pussy. My dick was throbbing hard. She finally started groaning and breathing hard and shaking. When she finally stopped, she rolled over to her side and just laid there.
I quickly tiptoed back to my room, where I locked my bedroom door, took off my pants, and jacked off. I came in seconds after watching her. I never saw her do that again but I get hard as a rock every time I think about it.
