My father-in-law would always try to touch my boobs, grab my pussy or ask me to let him fuck me. I always said no. I even told him I was gonna tell his son. He didn’t care, and he continued every time he got an opportunity. He wasn’t getting any sex from my mother-in-law so he was really horny. I did feel sorry for him. One day he stopped by our house unexpectedly. He had a key and so he came on in. I was in the shower and didn’t hear him. I just had a towel wrapped around me and was looking for some undies to put on when he came in the bedroom. It scared me to death. He knew I was in the shower so I guess he made his plan to get at me, which he did. I turned around away from him and he grabbed me from behind and I heard him unzip his pants. He was very strong and bent me over the bed ripped off my towel and stuck his very hard dick in my pussy. I tried to move but he begged me to let him fuck me while he was holding me down already fucking me. I must admit he had a very big dick. He was longer and thicker than his son. It did feel good. After he pleaded with me, I couldn’t say no. So, I quit struggling and let him do whatever he wanted. He fucked me from behind reaching around squeezing my tits. Grabbing my waist pulling me down hard on his dick. He turned me over on my back and stuck three fingers in my pussy and fucked me hard with his hand making me cum. Then he put his dick in me and fucked me for the longest time, rubbing my belly, squeezing my tits and telling me how good my pussy was and how badly he needed this. I was surprised at how good he was and how much I enjoyed it. He said he was gonna cum in my pussy whether I wanted him to or not. I said okay. His big dick was getting bigger and I knew he was getting ready to cum and he rammed it in me as far as he could. I felt the pulsing streams of cum as he finished. He hugged me and told me how much he appreciated me letting him fuck me. I told him it was quite a surprising pleasure. He said he might have to stop over again. I said I don’t think that’s a good idea but knowing how nice his dick is I don’t know if I could resist if he’s as persistent as he has been. I might have to let him unload in me again.
