After about 5 minutes of mouth kissing, it was getting a little uncomfortable with our height difference. So I sat down on the office chair and had he... sit on my lap.I pulled her face closer and resumed kissing. I could see that she was not very used to kissing so I guided her with slow kisses and she was following along. Then I cupped my hands around her right breast and started to fondle. She paused her kiss and looked at me and this time there was no shyness. She asked if the front door was. I saw the time was only 12:15 and there was still time for me to dress up and clean everything before the maid arrives. So I decided to watch some porn and shag off. I plugged in my headset and was on the bed naked, without even locking the front door. And I was getting in the real mood and was playing with my dick. This kept on going for some time. I wanted my manhood to get really hard before I start offloading.I was so into the videos, that I lost track of everything around me. And was. She concentrated on her dolls, ignoring him, as she usually did.She doesn't know what made her look up, at her grandfather. There was something wrong, she sensed it. Perhaps it was the way he held his shot glass, perhaps it was something else. She looked at the old man's face. She dropped her dolls and approached her grandfather silently. He no longer watched Lou, his eyes lost in the distance. His face trembled.Nothing like this had ever happened, but she sensed, as girls do, that there was. A few minutes passed and I unbuttoned her trousers and she gasped as I pulled them down leaving them just above her knees as my finger ran over her panties.Another couple of minutes and I moved over and pulled her pants down and took them off her feet, spreading her thighs I noticed she was wearing blue panties, as I spread her I touched the front of her panties with my tongue and she cried out “Oh God No there, please NOT THERE”.I obviously took no notice and pulled down her knickers,.
