I got a call from my son Roger the other day. He asked if my eighteen year old granddaughter Annie could stay with me for the week. Roger and his wife were going on vacation and Annie didn't want to go along. I asked Roger why Annie couldn't be by herself. My son said he would feel better if someone could keep an eye on her. I told Roger that Annie was welcome to stay if she wanted to.
Friday afternoon my son drove up with Annie in tow. She didn't look happy. Annie got out of the car and walked into my house. I waved to my son and daughter-in-law as they drove off. I took Annie's bags and took them into the spare bedroom.
"Are you hungry?" I asked her.
She told me she wasn't.
"You know where the refrigerator is, if you change your mind," I told her.
Annie went into the spare bedroom and I didn't hear from her. It was getting late so I decided to hit the sack. As I am alone these days, I have taken to sleeping in the nude. I shed my clothes and then got onto the bed. I must have drifted off when I heard a knock on the door.
"Can I come in Grandpa?"
I quickly got under the covers and I told Annie she could come in. Annie began to apologize about being mad. She said she wanted to stay at home by herself but her parents wouldn't let her. I barely heard what Annie was saying. I looked down and saw my cock bulge pushing on the bed covers. I wondered if Annie could see that as well. My granddaughter walked into my room and she sat down on the edge of the bed. I knew she could see my cock pushing on the sheets.
"Grandpa, do you have an erection?" She asked.
I couldn't say a thing, I was so embarrassed. Annie reached out with a hand and she touched the sheets where my cock was. Damn, my cock was starting to rise up. Annie was rubbing against those covers and I didn't know what to say.
"I've only been with one guy before," she told me.
Just like that, Annie pulled the covers back and out came my erect cock. There was silence for a few moments and then Annie reached over and took hold of my dick. She began to stroke my fat cock and I think I let out a moan as she did so. Annie made me more hard than I could imagine. After a few minutes Annie stood up and began to undress. My mouth must have been open when I first saw my naked granddaughter.
Annie was on the thin side. Her breasts were small and she had her pubic bush cut down to nothing. Annie climbed into bed with me and we sort of lost control of ourselves. We were soon kissing each other and I had a hand on one of her small nipples.
"Make love to me Grandpa," she said.
I knew it was madness what we were doing right then. It had been such a long time since I last had sex. I think I just lost control of myself. I flipped over and I got in between my granddaughter's legs. I pulled them apart and I took my cock in my hand. I looked down at Annie's face. She looked like she was in some sort of ecstasy. I did a stupid thing then. I guided my cock to Annie's opening and I began to feed her my cock.
Annie let out this cry as I tried to push into her pussy. She wasn't kidding. She probably had sex just the one time. Her pussy was so tight. I had difficulty getting my dick inside her. I went slow and was able to get a few inches inside her hole. What can I say? My granddaughter needed my erect cock and I was giving it to her. Annie placed her legs around my back. I kept feeding her until I had my entire length inside.
