Last summer we went to spend a couple nights with my husbands dad. He’s 78. My husband had laid out a pretty skimpy nightgown he wanted me to wear while we were there. He loves to show me off to anybody. He said his dad would love it. The first night after my shower I came downstairs in this thing. I had panties on underneath. I’m sure my father in law got a couple good looks at them. I made sure to lay on the couch where he could look up my nightgown. This turned me on so much. Teasing an old man. The second night my husband talked me into giving his dad a lap dance. My father in law sat in his chair and I can in with my nightgown. I slowly started dancing for him. Then I unbuttoned the front and with my back turned let it fall to the floor. I stood there facing away from him in just a thin white pair of panties. I turned around and let him see my tits. Though they aren’t very big they are perky. I could see he was hard. So I reached out and started rubbing his dick through his pants. I slowly unzipped them and pulled out his huge dick. I put my hand around it and rubbed his balls with the other. Then I got down on my knees and put it in my mouth. He rocked back and forth fucking my mouth for a couple minutes. Then I stood up and slid my panties down. I had shaved the lips but had a cute bush on top. He reached out to rub my wet pussy. I moaned. Then I climbed up in his lap and I sat on his dick. I thought I would cum right there. I moved up and down while he squeezed my little tits. My husband started videoing on his phone. I could feel him getting harder. I knew he was about to bust. He slid his hands down to my ass and let go. He started cumming so hard in me. I made sure to get all of it out. Then I took my panties and wiped off his dick. He was so appreciative he couldn’t speak. Afterwards my husband sent him some pics and videos of me so he could enjoy me anytime he wanted.
