We were visiting my daughter and son in law on Saturday. We had a few drinks and watching sport on the TV. After the game was finished everybody moved outside into the garden, except for me and my 11 yo granddaughter who was sitting on my lap at the time, as she always loves to do, the difference today was that she has been shifting her little ass around all the time on my dick which had a effect on me and caused my dick to rise like a flagpole, this even caused her to wriggle around more and at the end got my dick wedged between her ass cheeks.

When we were alone she turned her face to me and kissed me softly on my lips and told me she loves me very much.She suddenly jumped up and whispered that she was going to fetch a blanket and planted another kiss on my lips, this time letting her tongue push against my lips and with that she skipped and jumped out of the room while I was staring at her sexy little ass in her tight fitting denim shorts. My dick was raging like a fire and even though I knew I should get up and get out, I could not.

My granddaughter came back with the blanket, settled down on my lap and pulled the blanket over us. She then wriggled around on my lap until my dick settled between her ass, laid back and snuggled her face into my neck and gave a little sigh. I wrapped my arms around her and pulled her into me, her lips pressed against my neck which caused my dick to twitch against her bum. My head was spinning and my hands started to roam over her body, my right hand was searching for the little nipples on her chest that was recently showing signs off her body nearing puberty, while my other hand travelled over her thighs and up to her crotch area. When my hand stroked up between her legs she suddenly pulled her one leg up bending it at the knee which opened the access to her crotch area like a highway.I froze for a moment not sure how far I should go, that was when I looked down at my granddaughter. Her face was flushed, her lips moist and she was looking at me shyly but with a sparkle in her eyes that begged me to continue. I knew that there were a lot off people around and that I may be caught but I lost it then, bending my head down towards her face and then I kissed her softly playing with my tongue across her lips, she responded by sliding her one arm around my neck and pushed her tongue against mine, we were kissing like lovers not like grandfather and granddaughter while my right hand played with her stiffened little buds and my left hand found it's way up into the gap between her leg and the denim short. There I found her treasure covered by a cotton pantie and to my surprise I found it damp with her juices, when I touched her there she let out a little moan into my mouth.

That was the moment I heard my grandson as he came running into the house calling me.My granddaughter gave a little groan and quickly broke free from our embrace just as her brother came storming through the door explaining that I was needed outside in the garden.

After I persuaded him to go and tell everybody that I am coming I pulled my granddaughter against me and found her lips waiting for me. I knew I should not say it but I whispered against her mouth "I want you" upon which she responded softly with "I love you" then I stood up and went to the bathroom to get rid of all the pre-cum that was soaking my pants and went outside.

She never left my side for the whole evening. What should I do?
