I spent the next few days fucking Sarah repeatedly, taping it, and then making Steve watch the videos with me. He paid me ever more obscene amounts for each recording, until he sent me a full $1 billion for a POV video of Amanda sucking me off.
We went through it, frame by frame, while I narrated it and gave Steve "tips."
"See here, how she is taking the whole thing now? No more complaining before taking it into her throat?"
Steve nodded.
"When you get good with her, that's the end point you want to get to. Sarah on her knees for you, asking you to *please* let her suck your cock, then jamming the whole thing into her throat in one go?" I sighed and smiled. "It's really something special. Your wife is a special woman, Steve - you're a lucky man."
I clapped him on the shoulder and pretended I couldn't see his eyes were tearing up. I paused the screen, leaving the image of his wife Sarah looking up at the camera proudly as she took my cock to the root.
"Alright, I gotta take off for now. See you at dinner."
I walked out of his home movie theater and through the halls of his mansion. I almost felt bad - I could tell he was really getting his heart broken. Oh well.
Should have thought of that before, Steve, I thought. Once you steal my girl and my life's work, selling my invention for $10 billion, you give up the right to complain too much.
I walked out into the hot, bright sun. Steve and Sarah had their own private island in the Caribbean, and it was just the three of us here. When I reached the guest house, I checked my messages.
I had a couple from Dana. She was missing me, and, thinking of her, I realized I was missing her as well. She had sent along another couple of boudoir pics - not quite nudes, but their close cousins.
"Thinking of you..." the first one was captioned. She was facing the camera, lying on the bed, her smiling face framed by her blonde locks. The enticing curves of her ass were out of focus in the background.
The next one was significantly sexier. It was a selfie, on her back in bed. Her large breasts were bare, her eyes were rolled back in her head and tongue, dripping, hung out of her mouth. Her moist, bee-stung lips screamed sex. The caption was a continuation from the first one: "...In my throat."
"Jesus fuck you're so sexy," I wrote back. "I miss you too. I'm almost done here - I'll be home soon."
Then I brought up the Master PC program. I checked first on Dana. She had just read my text, and her settings were spiking. Her jealousy, affection, and arousal settings were all jumping as I watched.
My phone buzzed again. Another pair of captioned photos from Dana. The first one, again, was a little reserved. She was wearing a form-fitting dress that was riding up her toned thighs. Her legs were crossed, and she was sitting on the edge of a fountain. I could see several guys in the background, checking her out - I couldn't blame them. This one was captioned "Thinking of going out..."
I eagerly flipped to the next one, and was not disappointed. "...And what we could do when we got home," read the caption. Dana was on her knees, looking at the camera in mock astonishment, one hand covering her mouth like she was shocked. The fancy-looking club dress from the first pic appeared to have been torn off her, leaving her breasts encased in a lacy, skimpy bra. Next to her was an ass. A truly exquisite, mouth-watering ass, sculpted by years of exercise - Madison's ass. She was naked, bent over at the waist. She had a hand on each cheek and was pulling them apart, making sure the camera could see both her holes - and her pussy was dripping. Her face was visible in a mirror over Dana's head.
Just then, Madison texted me. The two of them must be together right now, I thought. Madison's text was more to the point: "If you don't get back from wherever you are and fuck Dana until she can't stand soon, she's going to go insane. She's climbing the walls."
Then she sent a follow-up: "If you need any help with that, you have my number ;)"
I looked back at Dana's profile. I checked her monogamy and relationship settings - they were both still high, showing she was still dedicated to me and our relationship. I breathed a sigh of relief, exhaling a breath I hadn't realized I had been holding. I was glad she wasn't about to go looking elsewhere, and I didn't have to tinker with her any more to stop her. I didn't like messing with her, I realized. I had chosen her by accident, almost - just totally at random - but she had turned out to be basically perfect. The only thing I had done to her was before we first met, when I made her believe we had been dating for a while. But I hadn't enhanced her body, changed her sexual appetites ... she was still her, and I liked that.
"I might just have to take you up on that," I messaged Madison.
To Dana, I wrote "I miss you so much. I'm wrapping things up. I'll be home as soon as I can. <3"
Ok, I thought. Time to put a bow on this thing with Sarah and Steve, finish the revenge, and get back.
I brought up Steve's profile and upped his Suggestibility to maximum, so anything I said would sound eminently reasonable. Then I had a better idea - I undid that change and instead upped his Submissiveness. If I told him to jump off a bridge, he wouldn't think it was a good idea - but he'd do it because I told him to.
Then I went to Sarah's profile and upped her Submissiveness as well. She had figured out that she could only cum when I was touching her, and she was hornier than should have been humanly possible, so I hadn't had much trouble with her - but I didn't want to have any issues at this stage.
Checking the clock, I realized it was almost lunch time, so I headed back up the hill to the mansion. I bumped into Sarah first. She was on her hands and knees, working in the garden, and I took a moment to admire her rear end before she noticed I was there.
"Hey," she said, standing up. "We got a present for you. It's inside." She pointed toward the front door, which was standing open. I could see a large package inside - a gift wrapped box, close to three feet on a side, with an enormous bow on top.
I looked at her a little questioningly.
"Steve wanted to get you something - said you'd been doing him some big favors, something about movies? And I knew just the thing." She pulled off her gloves and dropped them on the ground near the freshly-dug dirt.
We walked in together, her arm around my waist.
"I know I said 'this is the last time,' this morning, but - what do you think about after lunch, you and I sneak away to -" Sarah cut herself off when she caught sight of her husband coming down the stairs. She still thought her cuckolding of him was a secret.
"What is this?" I asked excitedly as the three of us stood around the large package.
"A small token of gratitude for coming out here, and helping us out," Steve said. He had paid me $1 billion for cumming in his wife's mouth that morning, and still thought I was the one doing him a favor. I grinned widely - this really was too good.
"Open it, open it!" cried Sarah.
I pulled the lid off, and stood back in surprise. The enormous box had been a ruse; there was nothing large held within. It was a small set of car keys. Sarah bent over, taking the excuse to rub her ass against my crotch, and picked up the keys.
"Here!" she said.
It took me a moment to place it, but then I turned the keys over and saw the logo. They were the keys to the 1954 F-type, my dream car. I had told Sarah about it years ago, when we were together. On a trip home from her parents', we had pulled over and she had gone down on me while I struggled to form a sentence, stammering to concentrate enough to describe the vehicle.
I was actually touched, for a moment. "Thanks, you two," I said. Steve shook my hand, then Sarah gave me a big hug. She pressed her whole body against mine - I could feel her breasts rubbing my chest, and the heat emanating from her groin as she rubbed it against my hip. I shot Steve a conspiratorial wink over her shoulder. He blushed and squirmed, looking away from her lewd display.
"And we'll pay to have it shipped back to the mainland, of course. Come! On, to lunch!" Steve said, and began leading the way out onto the deck.
Sarah and I sat down at the table as Steve began carrying out dishes for lunch.
"I've been working on this all day," he said with glee. "I woke up at three to make the bread from scratch!"
