When I was 17 my parents went away for a weekend. They asked my grandmother to stay at the house as they didn't trust me to watch my siblings while they were gone. The first night my siblings were asleep and my Grandma was in my parent's room across the hall. I was in my room smoking pot. When I get high I usually get extremely horny, so I stripped down to my tighty-whiteys, got throbbing hard, and started stroking my dick through my underwear.

I then got it in my head that I wanted my Grandma to see my hard cock. Being a waisted as I was I decided to go watch TV with her while just in my underwear. I stopped in the doorway and asked if I could watch TV with her. She looks down to the very visible bulge, then looked up and shook her head yes.

I sat down in the chair next to her slouched down so my bulge would be very seen by her. After a few minutes of her watching TV and occasionally looking over and staring at my groin, I was so dirty horny I could hardly stand it. I started rubbing my hand up and down my crazy hard dick. As I was doing this I noticed her looking over more often and for longer looks. This was making my cock throb like crazy. I then went for it, my heart pounding as I took my throbbing dick and balls out one of the legs of my tighty-whiteys and started stroking it slowly. Again, my grandmother started staring at my crotch more often and for longer times. also, she was now holding her boobs through her clothes. It was when she stopped watching the TV and started watching me completely that I went further.

I stood up facing her and removed my underwear. Then I started stroking my cock slowly, while still standing there. She moved one of her hands down to her crotch and started rhythmically squeezing. After about a minute of standing, I sat back in the chair and reclined it the whole way. Feeling crazy horny and high I started stroking hard, humping my hand and moaning. She was just staring at my cock, squeezing both her boob and crotch, and grinning slightly. I was extremely hard and horny and just started pumping really hard while squeezing and pulling my balls. Then I couldn't hold it any longer and shot rope after rope on my chest and stomach. As I was my Grandma gasp-moaned while pushing on her crotch hard. When done I laid there rubbing cum all over my chest, stomach, cock, and balls, and lightly moaning.

After a few minutes, my grandmother handed me the tissue box. I cleaned up some then got up to leave. My grandmother pointed to my underwear on the floor and said, "don't forget those", as drops of cum fell from my dick. I picked them up and went back to my room. In the middle of the night, I woke up extremely hard again. Ended up jerking off again to thoughts of my Grandma.

Over the years, every once in a while, I would end up doing more naughty things with her.
