Granddaughter's Visit.

My daughter -in- law has always been very flirty with me even in front of my wife. I have always thought that someday things might go all the way ,but it hadn't yet. This brings me to her daughter my granddaughter. She's very attractive not a model ,but a sexy slightly plump girl she just turned 21 2 months ago. Anyway my wife and daughter-in-law were going shopping and the granddaughter didn't want to go so they asked if I was alright with her hanging out at our house until they got back. I really didn't have any plans so said sure we'll have a nice visit while you two are shopping. Little did I know how nice this visit would be. Once the girls left it was me and Samantha alone so I asked how things are going for her and about her job. We made small talk for maybe 20 - 25 minutes or so when Samantha looked at me kind of funny. She said Gramps can I confession something to you and you promise you won't be mad or tell anyone especially my mom. I said sure Sammy you can always tell me anything and I could never be mad at you and I can keep a secret. Well you know how mom's always flirting with you. I said yes, but it's harmless fun. Then she told well Gramps it makes me mad. I said really why? Then she said because if she ever went further and you two ended up having sex you would not want me. I was confused and said sweety I wouldn't do that with her and even if I did I would always want you thinking in an innocent manner. Sammy floored me when she said really Gramps you want to have sex with me because that's all I think about. I've wanted to fuck you since I was 15 and I caught you coming out of the shower naked. I barely remember that. I said Sammy that's not what I meant when I said that, but now that you said that I would love nothing more than to fuck you. She smiled and grabbed my hand and led into the guest bedroom. Once inside we stopped and I was already hard she took me in her mouth for a quick taste. Gramps I want to feel you cum in my pussy I'm on the pill so it's okay to cum in me. I mounted her and slowly started fucking that sweet pussy of hers. I only lasted about 3 minutes before I filled her with my cum. Once I pulled out she demanded I lick her clean which I did without hesitation. I've always wanted to eat a creampie but my wife thinks it's gross. To be cont.
