I had been estranged from my father. He had been an absolute rat to my mother. Now here he was telling me, he had never been happier since meeting his new partner. He was asking if I would come to his wedding. I had no respect for him and didn't want to go or see his new friend. Then curiosity got the better of me. Who could have taken the place of my mother. I eventually agreed to meet them in a restaurant a few months before the marriage. On my arrival my father was sat with a young woman. She looked younger then me. I was twenty two and she looked late teens, certainly younger then myself. I thought it must be his new lovers daughter. Then he introduced Amber as his betrothed. He had replaced my mother with a girl, not a woman. She was pretty and was interesting to talk to, unlike my father. I enjoyed looking at her large tits. I could see what my father saw in her, but couldn't see what she could've seen in my father. During the meal she was complaining that she had a dress fitting, but hadn't got transport to get there, as my father had a two day trip away for work and she didn't drive. I quickly offered to take her. I collected her from my fathers new home and drove the eight miles to the shop. Talking to her, she had few if any friends and her parents disapproved of her upcoming marriage and had broken off all ties with her. She couldn't understand why they all disapproved so much. She had the fitting and there were a few more small alterations to be done. She looked stunning in the dress and the assistant had initially thought I was to be her husband saying that I shouldn't see it before the big day. The assistant was very apologetic when I told her that it was my father who was marrying Amber and not me. The dress showed off her ample bust without being vulgar. Fitting over I offered to take Amber for a coffee. She quickly accepted the offer. Over coffee she was getting upset that I was the only person from our family that would attend and nobody from her family was going to attend. The only other people would be her two remaining friends and some work friends of my fathers. It was going to be a very small do. After coffee I took her back to my fathers house. She was still upset as we arrived and then got frightened when we found the front door swinging in the breeze. I went in with her and we went from room to room and by the time we were in their bedroom we had checked out the whole house and there was nobody there and nothing taken or damaged. She must have just not closed the door fully. Stood in the bedroom I took advantage and moved in and kissed her. She started to pull away and perhaps slap me or something. Then it was clear that she changed her mind as she pushed her tongue into my mouth and wrapped her arms around my neck. I ran one hand down her back and onto her tight little arse and the other up her side under her tee shirt and into her bra. I had a handful of her large breasts. She was gasping into my mouth as I rolled her large stiff nipple around in my fingers and I groped her arse. Then I grabbed the bottom of her tee shirt and pulled it up and off. I could see more of that lovely creamy flesh that I saw in the dress shop and put my face between the mounds. It was lovely and warm and the smell of her perfume was heady. I reached around and undid her bra and it fell forward. I moved my face away just long enough to totally remove the bra and then I had a nipple in my mouth. She was beginning to groan at the pleasures in her breasts. I would suck one and maul the other and then swap around. I did this for some while, before I changed and had both hands on her arse. I was still sucking her tits as I groped her cheeks, Then I reached around and undid her jeans button and pulled down the zip. Then I was on my knees pulling both garments down together. I had to stop and undo her shoes to enable me to pull them off completely. I was now staring at her tight looking fanny. The fanny my rotten father was fucking. I licked up her pussy and ran my tongue around her clit. Her legs started to buckle, so I stood and lifted her and laid her gently down on the bed my father would fuck her in. I was quick to get back to licking and sucking her pussy. Her hands were on my head as I licked and sucked at her. My hands were busy undoing my own jeans and pulling them and my pants off along with socks and shoes. As I continued to lick her I now had free hands and reached up and was rolling both nipples around and pulling on them. She was moaning loudly as I pleasured her. All was fine except that my hard cock wasn't getting any attention. I grabbed her feet and took them with me as I worked my tongue up her body over her navel and over her tits and stuck my tongue into her mouth. With her feet over my shoulders I had lined my cock up and the tip was touching her pussy lips. "We shouldn't be doing this," she gasped into my mouth. I took my mouth away from hers just long enough to tell her I knew but wasn't it good. Then I was driving my cock into her pussy. She was tight and it was several thrusts before her pussy gave in and let me push all seven inches into her. Then she was rocking with me as I plowed in and out of her pussy. I was kissing her and rolling her nipples and fucking her all at the same time. She was moaning as best she could with my tongue in her mouth. Then she was shaking. It started with her legs and seemed to work up and all through her body. My excitement also rose and as she shook I slammed in hard and released my cum deep inside her pussy. Then I collapsed on top of her. Eventually we revived from our mutual high and rolled apart. It was now she suddenly realized that I had cum in her. I could see panic in her face as she told me that she used condoms with my father and she was not protected. I really did not care and thought it serves her and my father right if she was pregnant, but I didn't tell her that. Instead I reassured her that it would all be ok. I cuddled up to her and stroked her lovely tits. I could see her eyes closing enjoying the sensations I was giving her. It was some while before my cock started to recover and rise once more. With just a little protest from her that we shouldn't I rolled her onto her front and pulled her small arse skywards and slowly pushed my cock into her pussy again. This time I fucked her long and hard for over twenty minutes. She shook uncontrollably as I fucked her going from one climax to another, until I finally came and pumped a second load deep into her pussy. We fucked several more times that day and night as I stopped over. The next morning I again fucked her, this time in the shower. Each and every time I left my cum deep in her. Then I had to go home. Eight weeks later I attended their wedding and at the small reception my father was telling me he was so pleased that I had come. In all just fourteen people attended as well as the newly married couple. Later when she managed to get me to one side Amber informed me that she was pregnant, She was ninety percent sure that it was mine. I told her, "Good luck with that mummy. Hope you and daddy will be happy with my new brother or sister." I left the party such that it was shortly afterwards. On their return from their honeymoon, my father rang me with the good news that he was going to be a dad again at the age of fifty one. I told him I didn't want to know and put the phone down on him. I haven't seen or heard from them since. My brother or sister would be nine now and my sixty year old father would be being run ragged by a soon to be teenager. serves him right.
