My grandmother (Nana) lives with my mom and my younger brother George. My dad died several years ago. Nana is sixty four but her body looks like it's the body of someone around early fifties. She has no weight issues and her tits are quite large. Nana likes to wear dresses with a low cut front. I think she likes to show off her nice big tits and I don't blame her.
On more than one occasion Nana has caught me checking out her tits but she has never said anything to me. One of the reasons I can't help checking them out is because mine are tiny and I'm more than a little envious.
One day last week Nana wore a particularly low cut dress and my mom told her she looked lovely in the dress. I looked at her chest and saw that Nana wasn't wearing a bra. I could see her nipples poking at the dress material. That same night mom and dad went out for the evening and George was in his room at the computer. I was in the kitchen when Nana came in and I couldn't help but look at those tits again. Nana walked over to me and I'll never forget what she said to me. "I know you're dying to see them aren't you?" I knew exactly what she meant and I nodded my head.
Nana pulled the dress straps over her arms and then pulled down the front of her dress completely exposing both tits. Her areolae were real wide and very dark with a big nipple in the middle of each. I just stared at them. Nana took my hand and placed it on one of the tits. I fondled it and quickly started playing with the nipple. I could feel it hardening as I squeezed it. I then switched to the other one and played with that one. Nana then took my hand away and told me that was enough.
I asked her if I could put one in my mouth and was told no. Then, she put her hand up her dress. I watched her pull aside the crotch of her panties and put a finger up her hole. After a few seconds she took her hand out and put her middle finger to my mouth. As I opened my mouth she told me to "suck it off." That's just what I did and then I went to my room. You know what I did then.
I don't know if anything else will happen with me and Nana. I doubt it. I am going to force myself not to look at her tits any more.
