Twelve months ago, next month, I got married to Fiona. Up until last month I was still very much in love with her, and had even booked to fly out on a surprise anniversary vacation. That was until I found out by total luck, she'd sucked off and then fucked a guy three weeks before we wed. I know for definite she did, because the guy who she had a night of "Horny anal sex" with, used to work for my company. One I set up a couple of years before Fiona and I married. During a night out with some of my employee's, he bragged about fucking a woman a year ago, who was about to get married to a logging businessman. When he went into detail about what they did, what she looked like and then told me her name, I froze with anger. She'd told me she was visiting her mom that weekend, when in fact she'd arranged to have one final night of sexual freedom, letting this guy do anything he wanted to with her.
The following week I made sure the guy got sacked, amongst other things which befell him. And then drove over to my wife's moms home. Louise is my mother in law and she's what you might call, one cock hungry slut. She's divorced, after Fiona's father caught her in bed with two teenage guys. He beat them up and dumped her. Even though I'd had many opportunities to bed the bitch, when she'd almost weekly at one stage asked me to fuck her, I'd always refrained from doing so, telling her I was marrying and then married to her daughter.
The week after I found out about Fiona and her pre marital anal fuck fest. I pulled my car onto Louise's drive, got out and walked directly into her home. Taking her by the hand when she asked why I was there, I lead her to her bedroom, pushed her onto the bed, spread her legs and ripped her panties off. Her smile was like a Cheshire cat as I buried my face into her already wet pussy. I'm no Casanova, or very well endowed at seven and half inches. But when I'm horny or like last month, horny and angry, I remain erect for a hell of a long time. In the two and a half hours I was in her home, I must have fucked Louise in every conceivable position known. And in every orifice. I fucked her mouth making her gag. I fucked her pussy until she came, I lost count how many times, and I took great pleasure in brutalising her asshole until I'd cum up her rear fuck hole twice. By the time I walked out, Louise was begging me to call back round another time.
Back at home I waited for my wife to get in from work. I was going to have a shower, but decided against it. That's because as soon as Fiona walked into our bedroom with me being naked, I had her sink to her knees and take my cock into her mouth. The same cock which had not long been fucking her moms mouth, pussy and especially her asshole. I took immense pleasure watching her gag on my cock, as I forced her to deep throat me. Then when I was ready to fuck her, I threw her onto our bed, ripped off her panties as I had her mother earlier and thrust my cock straight into her asshole. I listened to her moaning about not having used lube, but I didn't care. Pushing her face into the bed I fucked her harder, until I had the image of the guy she'd fucked in my mind. Telling her she was MY slut, I spurted my cum deep inside her ass.
I left her lay on the bed wimpering about me being too rough. Rough isn't what I'd describe what I'm now doing with her mom each week. Downright animal fucking is what we get up to. I treat her like a whore and I genuinely think she loves it. There is nothing we haven't done. From drinking my piss as I pee all over her, to having me fist fuck her asshole after I've fucked it and cum deep inside her. Having my own company which I've worked damn hard for, gives me lots of time to escape the office to drive the forty minutes to Louise's home. She's always ready to have sex and I never now dissapoint her. I've even got to the point that if Fiona found out, I'd tell her if she doesn't want me pleasing her mom, she can fuck right off. Because I'm going to continue screwing her piece of dirty shit mom, until I get bored, or I decide to leave them both.
