Holy fuck was my stepmom hot. I mean... damn. She'd been hot before. A gold-digging bimbo, true. But a hot gold-digging bimbo. But now...
I couldn't help myself. She was fucking smoking. "Get on my cock, bitch," I snarled at her. Time to take my revenge on the prissy little bitch.
"Yes, Master," she said appearing completely unphased at being called a bitch. She walked over to me, hips swaying almost hypnotically. She looked me in the eyes and sank down on my cock in one motion. Her cunt was impossibly tight and wet. It felt perfect. I moaned and grabbed her tits roughly as she worked herself up and down on me better than any person I've ever known. Even, if I'm being honest, better than Rhonda who I thought was basically a sex goddess already!
"Enjoying your new toy, baby?" Rhonda said somewhat snarkily. Let's be honest though, you can't be THAT snarky when you're stripping out of your clothes at the same time.
"She's fucking tight as hell. For a dumb cunt, she sure can fuck now."
"That's the magic, baby. She's a sex genie. She's made for it. Wired for it," she sounded almost reverent as she walked over to the side of us. She grabbed Laurie's hair and pulled the new genie's mouth to her own aching pussy. "Suck it, slut."
"Yth, mthtrth," Laurie managed as she started sucking. Rhonda ground the new genie's mouth into her cunt and both girls were quickly moaning.
"I wish I had the perfect cock for whatever woman I'm with," I said.
"Yth, Mthtr," Laurie mumbled and suddenly my cock surged. Laurie's moans of pleasure went into overdrive as she started cumming on my now perfect-for-her cock. Her tongue must have gone into overdrive on Rhonda as she had her own orgasm, flinging the blonde bombshell's head back as she did. Laurie turned her attention back to me as she gazed adoringly at me. My cock was sliding in and out of her smooth, slick cunt and she was loving it.
I remembered all the times she'd been snarky and pissy with me though. "Except for you, slut. I wish it was an inch too big for you but you are still addicted to it."
"Yes, Master," she said and then she screamed and whimpered. She stopped slamming herself down on me and instead started going slower, sinking herself down onto my shaft with effort and sheer willpower. Each time, she looked like it was a supreme effort but she was obediently doing it regardless. I flexed my cock as she bottomed out each time and enjoyed watching her gasp as it filled her up almost to the breaking point. With her exquisite tightness and muscle control, I didn't last long and started cumming as I filled her up. She came again as I spurted inside of her before collapsing off to the side as she twitched.
Rhonda and I laughed at our new little fucktoy and I was already thinking of all the ways that I might use her. Rhonda gestured at my juice covered cock and I looked down. It was mammoth. "Apparently sex genies have a pretty high capacity for cock," I said. It was almost comically large as it hung down below me, nearly falling to my knees.
Rhonda dropped to her knees and started sucking at the head. As soon as she did, my cock began to shrink back to a more normal size. It stopped a couple inches longer and much thicker than my old cock, however. "So all those times you said my cock was perfect?" I asked.
"Perfect enough, baby. But damn is it yummy now," she said and she sucked me down in one go. I felt the back of her throat as she deep throated me like a fucking pornstar. When she came off my cock she looked up at me for a second and mumbled, "Sex genie's taste yummy." Then she went back to sucking my cock. Despite having cum inside Laurie only a few moments earlier, my cock was already hard and ready for my hot girlfriend.
Laurie was sitting on her knees, watching us with utter reverence. I guess it made sense. We were her owners now. The magic probably compelled that kind of attitude. "Fuck, how am I so hard so quickly?" I asked.
"You wanted the perfect cock for any woman you're with, Master. Mistress's perfect cock is one that can cum 37 times without resting."
"37?!?" I asked with a shout. Rhonda simply looked up at me and gave me a sassy shrug before diving back down onto my cock. "I'll never have the stamina for something like that?"
"You can if you wish for it, Master. If it relates to sex, I can make it happen," she said it sweetly. Part of me didn't want to trust her. This was my Dad's second wife. The conniving, scheming bitch who'd tried to steal my inheritance. But Rhonda had assured me that not only was she now completely obedient and loyal, she was also 100% devoted to her owners and wouldn't even WANT to harm them let alone be capable of it.
"Okay, fine. I wish I had a super fit body," I said as I face fucked my girlfriend. Suddenly, I felt better than I'd ever felt. I wasn't overweight before but now my abs were showing prominently. My skin tightened and muscles grew. I was cut like somebody in a movie. Rhonda looked up at me and mumbled approvingly before renewing her effort on my cock. Her technique was absolutely perfect as she sucked me down hard and fast. I gripped her hair and took control, shooting my cum down her throat with a shout.
The three of us played around some more over the next couple hours. I didn't cum 37 times but I did lose count. So did Rhonda. As we laid there talking, I kissed Rhonda and said, "You are terrific baby. All this is because of you. I couldn't have done it without you," I said. "Don't you want something for yourself? Some little improvement or something?"
"No, baby. I'm fine. You saying you want me improved?"
I knew a girl's trap when I heard one, "No, baby. No need for changes, you're perfect the way you are."
She smiled and nodded approvingly. I mean sure, slightly bigger boobs might have been better but other than that, Rhonda was almost as impossibly beautiful as our new sex genie. I shrugged. I could have any girl I wanted now. Crazy impossible sex limited only by my imagination. Of course, so could Rhonda I suppose. Did I care? I mean... I didn't want some other guy fucking her really. We probably should have talked that out.
"Are you going to... you know... fuck other guys?" I asked.
