First time poster, so be nice.
A couple of years ago I was broke and had to move in with my grandmother. Not too bad, she cooked for me... Anyway, one day my doctor's appointment was cancelled so I came home earlier than usual. Since it was just us girls, I didn't bother announcing myself when I came in. When I opened the door to my room (OK, the room she let me use) I had a quite a shock. Right in my face, so it seemed, was a pink, wet, hairless pussy with a dildo sliding out of it. The upper half of the woman's body was mostly under blankets. The lower half looked like a middle-aged woman, or maybe even younger. My immediate reaction was that a stranger had broken in and was masturbating in my bed. To my later embarrassment, I blurted out, "Who the f*ck are you?"
I was shocked when my dear grandmother got up and ran out of the room. I didn't know what to do. Obviously I wanted to apologize for cussing her out, but I figured she was mortified, so I left her alone. A few minutes later she came back in a bathrobe and said she wanted to explain that she wasn't a "creep" (her word), but being in my room made her feel like a young woman again. "You LOOK young!" I said. Grandma was confused and pointed at her wrinkled face and white hair. Feeling a flush coming to my face, I pointed at her lap.
This provoked quite a reaction from grandma. Honestly, she stood up and said, "Woooooh!" She was clearly quite delighted that someone thought she had a young-looking body. To my further shock, she asked, "Do you want to take another look?" Without even thinking, I said yes.
Grandma opened her robe and I had quite a long look. Her B-cup breasts looked surprising perky. I held up my hands to them, and she nodded in consent, then I gave them a squeeze. Considering she was over 70, they were pretty firm. Then I looked down at her vag. Although my first impression was that she was shaved bare. I realized that she had a fine layer of salt-and-pepper hair. Her pussy lips were still visibly wet. "I hope I have your genes," I said, "you look great." She smiled and spread open her labia. Her vagina looked pink and fresh, and my mild lesbian tendencies started to come out. I realized that I wanted to go down on her. This felt pretty weird, so I said "Thank you" and left the room.
