On February 8th 2017, I was retained as a private investigator by an old school colleague to investigate his mother-in-law. Sadly Ben's father was diagnosed with cancer and had been given six months at best. Ben was more than a little skeptical towards his MIL as she had married his father just seven months earlier. She had been retained as his nurse and now stood to inherit virtually all of Ben's fathers considerable wealth. Ben had a copy of the will and it was grim reading on his behalf. One good point was the clause that if Rita was unfaithful during their marriage, that the will all reverted in Ben's favor. Ben thought she was already being unfaithful. I followed her for three days and although I had my suspicions I didn't actually see anything to confirm it. Then I bumped into her, literally coming out of a Chemist. Some of the contents spilled onto the pavement. I went to her aid to pick her belongings up. On the top of her bag I spied a pregnancy test. From what Ben had told me of his fathers health the chances of any pregnancy being his was slim to zero. She smiled at me and asked, "Haven't I seen you somewhere else before?" I told her that I doubted it and that I had one of those faces, besides I would remember such a beautiful woman had I seen her before. Then she was flirting with me quite outrageously. I decided this was my chance to get in with her and asked her out for dinner. She hesitantly agreed, but would not let me collect her, Instead we arranged a time and a restaurant. Later I reported back to Ben. It wasn't enough to overturn the will, but a start. I set up my apartment with four cameras that all had movement detectors on it in the hopes of getting her back to my house. Unfortunately after the dinner Rita returned home without any shenanigans. Not even a peck on the cheeks. I did manage to arrange a second date for a show in town. I informed Ben not only of the evening, but also of the coming evening. Again I had set up cameras and even one in my car. The show was good and I even managed to put an arm around Rita without any resistance. After the show we went for a drink in a nearby bar and I invited Rita back to my apartment. Again hesitant as she resisted the idea, but after quite a lot of persuasion she gave in to my suggestion. Once in my flat she allowed me to take her coat and give her a peck on the cheek. She then pulled away. I poured us some drinks and we sat opposite ends on the couch talking. I asked about the wedding ring on her finger. She told me that she was married, but her husband was sick and not expected to live too much longer. She was very cold the way she talked about him. I displayed sympathies with her. She went on to say that she would be glad when it was all over. I asked if she didn't love him. "Oh no, I never loved him. If it wasn't for his money I would have been out of there ages ago," she informed me. If it wasn't for the fact that I knew that Ben's father was dying from cancer and was diagnosed prior to her being retained, I could have thought that she was somehow killing him. Then the heartless bitch laughed and said, "He couldn't even fuck me. I have to wank him off most nights. He want's me to suck him off, but I'm not sucking his weedy little cock." I joked, "well how about sucking my cock?" She said that sounded a much better offer. With that I stood and undid my trousers and released my seven inches for her to look at and possibly suck. Rita's hand stole forward touched my cock. It twitched at her touch. "He likes that," she said, just before she swooped down and sucked my cock deep into her mouth. She was well trained in the art of cock sucking and almost caused me to spill my load. I stopped her and suggested we get more comfortable. I led Rita to my bedroom, where I removed her clothes before loosing my own. Then onto the bed, I dived between her creamy white legs and kissed my way up to her pussy. The lips had already peeled apart showing me the way to her opening and her clitoris. I went for the clitoris and sucked it into my mouth and worked it over. Rita was moaning at the assault on her little nub and was pulling my head into her as if to tell me that I wasn't getting away until she was done. It wasn't too long before she screamed her way through her first orgasm. It wasn't to be her last. After several more minutes she was building towards a second orgasm. She was screaming at me not to stop, not that I would or wanted to. Then she gushed her juices into my mouth and onto my face as she came again. This was when I decided that I now needed some relief and climbed up her orgasm wracked body to take aim with my stiff cock at her soaked pussy. She gasped then groaned as I pushed forward and penetrated her pussy. Her fingers dug into my shoulders as I started to rock her and my world with my rhythmic poundings. The feeling were too great and we came together with me pounding my cum into her wet pussy. Then we were in a tangled heap gasping for our breath. As soon as she had recovered Rita declared that she must get back to her husband before she was missed. Once she had gone, I reviewed the films. Both the camera in the lounge and the one in my bedroom had captured more than enough evidence for Ben. For some reason I didn't tell him. I called Rita and arranged another meeting. This time she decided to come directly to my flat. I again set the cameras. This time she had barely cleared the door when she dropped her coat to the floor. She was dressed in a bra and panty set along with stockings and high heels. No dress! She wrapped herself around me and stuck her tongue down my throat. When she had her fill she walked away towards my bedroom. I followed and as I closed the door she was stood bent at the waist twerking her arse at me. I quickly dropped my trousers and pants followed by my shirt. Then pulling her panties to one side I drove my already hard cock deep into her pussy. I think she came straight away as I penetrated her. This didn't deter me from pounding away at her pussy and grabbing her swinging pendulous tits. Rita was groaning loudly, issuing her instructions to fuck her harder and longer and to try to get deeper. I tried to comply with her instructions, slamming harder at her fanny. Then she came with her pussy pulsing around my cock. It caused me to loose my load deeply inside her pussy. Then we were laying on the bed recuperating from our efforts. She was first to move and was kissing me saying she loved me. Not wishing to reply I took her titties one at a time into my mouth and worked them over with my mouth and tongue. Then she was pushing me onto my back and straddling me. I still wasn't hard so she spun around and rubbed her pussy into my face as she sucked my cock deep into her mouth. It wasn't long before my cock revived and was stood to attention for what was to come. Rita spun around again and this time she raised herself enough to position my cock and slowly sink down penetrating her own pussy on my cock. The groans were escaping her mouth as she rode my cock. Then she came again taking me with her. As we lay resting she told me that her husband probably had just a few weeks to go. She seemed pleased at the prospect. Then she again dashed away not wishing to be missed. I again reviewed the evidence and burned both lots onto a DVD for Ben. This time I rang Ben and informed him of the evidence. He was around in minutes and reviewed the film with me. Then he said could I meet her one more time. I was a little confused but agreed. He said that he wanted to be in the flat when she arrived and surprise her with his evidence. He had me burn another copy which he would post to his solicitor. Then he left. Next day I rang Rita again and arranged for a further meeting for that night. When she arrived she was naked under her coat and we again made our way to my bedroom. I made sure the door was ajar. The cameras were again set and running. She was quickly on her knees and sucking my already hard cock. Then I told her that I had enjoyed her riding me so much and could she do a repeat. She was quick to push me onto my back and straddle me. Rita slowly slid down my cock to fully penetrate herself and then began to ride me. She was good, very good, even excellent. Then I could see Ben stood behind her. I could see he was fiddling with something, but couldn't see what. Then Rita yelped loudly as if in pain. I immediately knew what he had done as his and my cock gave him away. Ben had stuffed his cock deep into Rita's arse. I pulled Rita tight to me as we both continued to pound away at our respective holes. Me in her pussy and Ben in her arse. I stuck my tongue down Rita's throat as she got used to the double penetration. Then she was even moving to get the best out of the ride as we continued to kiss. At this point she still didn't know who was fucking her arse. Then the pressure on her pussy and arse caused her to come. It looked a magnificent orgasm as she moaned and groaned her way through it. Then with the additional pressure from Ben's cock, he and I both came in our respective holes. Ben slumped to the floor and Rita was collapsed on top of me for several minutes. Then she rolled over and off me. It was now she saw Ben and screamed. Ben had recovered enough to stand and an argument ensued between Ben and Rita. The crux of the argument was that she was just trying to steal Ben's inheritance. Rita was trying to say that she loved his dad. Ben told her that all she loved was money and that now she had been screwed in more ways than one and his solicitor would revoke her from the will. Rita dressed in just the coat she came in and slammed my door as she left. The following afternoon I was with Ben at the solicitors watching the film. He said there was enough evidence to revoke her from the will and not to worry she would not see a penny. I went with Ben to his father's house. Rita was in the throws of packing up her stuff. Ben told her what the solicitor had said. She then claimed that she was pregnant with Ben's father's baby. I reminded her that she had told me that she had never had sex with him and had just wanked him off. She tried to claim that she had forced some of his semen into her pussy after wanking him off, showing Ben her pregnancy test. Ben just said that a DNA test would be required for her to prove it and without it she wouldn't see a single penny. Then Rita left with her belongings. Neither I nor Ben ever saw her again. It's a shame because she was a marvelous fuck, but completely untrustworthy. It was three weeks later Ben's father sadly died, and Ben did indeed inherit the lot. I still look at the films wondering what might have been had I met her under different circumstances.
