I have sex with my husband's grandfather. He's almost 70. He lives alone. I went to visit him wearing a skirt one time, and he said how lucky my husband is. Then later he said he loved seeing pretty girls in short skirts. I thanked him and he said he really liked it when he saw up their skirts. I did the "oh grandpa" laugh, then turned in my seat so he got a good flash. He got hard right in front of me. I giggle and said I could see he was getting excited and he said he really liked my pink panties and if he was a younger man he'd love to get inside me. I said he was plenty young and I walked over to him and sat my butt on his lap. I turned in his lap and we started kissing. He looks good and his dick was really hard. We kissed while I pulled his dick out of his fly, then I put my knees on either side of him on the chair and pulled my panties to the side. I eased down on him and we slowly fucked while we kept kissing. We do it whenever I can visit him without my husband. He pays me $100 to do it without protection so he can make a baby with me that only he and I will know is actually his.
