Today, all she said was, “Hurry up and cum for me, Slade, before Mom and Dad get home.”
I pushed up inside her in one long, pulsating stroke, perfectly content to take my time. Iris was more than just a hot body now. She’d learned a lot in the past couple months, and I’d learned that I was a damn good teacher. I’d seen her plump lips wrapped around my tip more times than I could count, and now when I plunged to fruition inside of her, she knew how to roll those hips and make me groan.
She was doing that now, urging me to finish, to leave all evidence of our forbidden lust inside her. Sweet, innocent Iris was on birth control now—I’d convinced her it was easier for both of us that way. No condoms to hide. Just my stepsister strutting around with a warm, creamy center.
That thought alone almost made me pop. Christ, I had to chill. I had to make it last. Because if everything went according to plan, then this would be the last time I got to fuck her.
Goddamn, some part of me was gonna miss this.
“I’m almost there,” I assured her through gritted teeth, leaning back a little to watch my dick speed in and out of her. I was covered in her desire. Iris had a hair-trigger, and she’d already gotten off multiple times, soaking the counter and me in the process. When my tip left the clinging wetness of her core, it made this popping sound I just couldn’t resist. Normally I’d have lost it right then and there, but the way my stepsister was digging her nails into my chest was killing me.
“Watch the tattoos,” I whispered. They were new and they were sore, and when Iris grasped them, they burned like hellfire. Which, given what we were doing, was awfully fitting.
“Sorry,” she moaned, leaning her head back so the damp curtain of her hair tumbled down her shoulders. I kissed the swan-like curve of her throat and she panted for me, her tits bouncing with the effort. Keep it cool, Slade. You can’t finish yet. Still got a few minutes…
“You’re close, Slade. I can feel it.” I drew back and her gaze met mine, hazy from her most recent orgasm. Her lips were swollen too, puffy and red, first from sucking my cock, then from my mouth on hers, stifling her moans and screams. “Cum inside me, baby. Please. Someone’s gonna catch us…”
Of course they are. That’s the point, Iris. But if she’d known that—if she knew this was all just a way to piss off my dad and put my brand new stepmom in her place—she never would’ve let me inside her. And that would’ve been a shame, because then I wouldn’t have known that turning a virgin into a succubus was a very worthwhile pursuit.
I couldn’t tell her the plan. Instead, I reached down between us and jiggled my thumb against that little bud I knew would send her over the edge again in no time.
Iris’ eyes widened. Her breath caught. “Oh, Slade. I can’t take it…” She raked her nails over me again and I just barely twitched out of range before she drew blood from my tattoo again. “I’m gonna…”
“Scream,” I told her, pumping in harder, faster, pushing her limits as well as my own. God, she was tight, and the way she writhed all over me was making my toes curl. “It’s our last time together, Iris. At least, for a while. I wanna hear you, baby. C’mon.” I turned the movement of my thumb into something more urgent, a tapping that made her wail. “That’s it. Louder, Iris. Scream for big brother.”
Yeah, that was nasty. But isn’t all sex, at twenty-one? And anyway, it worked. Shamefully, it turned us both on.
Iris began to shriek, spreading her legs wider to take the pounding I inflicted. She’d forgotten all about our parents, about what we were doing, about where we were doing it. She forgot how bold we were and how we were damn near out in the open. I could see it in her eyes when she looked up at me, her teeth embedded so deep into her lip that she’d broken the skin: all Iris Walker was thinking about, right at that moment, was cumming on my cock.
Shit, I was thinking about it, too.
Right up until the moment the pool house door opened.
The sounds that followed are ones I’ll never forget. The high-pitched cry of Iris helplessly surrendering to her orgasm, almost drowning out the sharp click of the doorknob turning. Then the little whine of the hinges as the door swung in, flooding the room with daylight and a single shadow, one that looked an awful lot like my dad’s.
Sweet vindication filled me as I filled Iris right in front of him. I couldn’t tell which was better: revenge, or my orgasm.
I expected a whole lot of yelling next. I thought Iris, for sure, was gonna start to scream. And my dad had always had a temper, albeit only a verbal one. I could almost taste his bellow on the back of my throat as I swallowed, turning toward him, following Iris’ horrified gaze.
His face was ashen. There were deep, dark lines where none had been before. His eyes, cold as ice, made my skin prickle with pins, needles, and goosebumps. There was anger in him, all right, but it wasn’t the hot, explosive kind I’d anticipated. This was the silent kind, with a warning vibration that made the hairs on my nape stand on end.
Iris was the one who spoke first, only it wasn’t really a word that escaped her lips so much as a strangled sob. The smirk on my face faltered for a fraction of an instant. I hadn’t been expecting that, either—that the sound of Iris’ grief would put a little crack in my stone heart.
“Is this what you texted me for, Slade?” my father said. Disgust shimmered in his eyes, pulled taut at his lips. “You wanted me to see this, didn’t you? That’s why you said your mother and I needed to come home so urgently.” He shook his head. “Thank God she’s still in the main house.”
“You did this?” Iris whispered, lip curled, brow furrowed tight. There was a note of disbelief in her voice at first, but the longer she searched my face, the more her denial abated and turned to rage. Disgust. “You bastard. You… did this. Used me.” Then she lost all expression, staring blankly at the floor. “Oh, my God. Everything you said was a lie…”
I knew what she meant. I knew she wasn’t talking about the little stuff. Not about how I’d told her she was pretty, or that she had the best rack I’d ever seen. She was talking about those three little words I’d said. The ones I’d lost sleep over, thinking maybe I’d pushed it too far.
I love you, I’d told her once, just to get her legs open. Or that’s what I told myself. Because thinking any other way, entertaining any other possibility, might make me back out. Might change my mind. Might fuck up all my plans to get even with the man who’d used my mother until she was dead, and then traded in her memory for a younger model.
My father inspired a rage so strong in me that sometimes, I couldn’t see straight. Feeling anything for Iris, anything at all, was a threat to that. Because every time I even thought about the idea of those feelings, my vision got blurry in an entirely different way.
And that just wouldn’t do.
“Get out,” my father said. Despite how low his voice was, it seemed to shake the room. “Get out of here, Slade. And don’t you dare come back.”
Iris withered as I withdrew, covering herself with her arms and legs while I pulled up my swim trunks. I risked a look in her direction and my stomach sank. Those eyes were wide again, but not with pleasure or sweet naiveté or even shock. They were wide with pain. Wide with rage.
How could you? her gaze said to me. I just gave her a shrug and watched her eyes get wet.
It didn’t matter how hurt she was. The fact of the matter was that Iris was better off without me. I would have told her as much, if she’d have listened. If my father would’ve let me stay in the same room with her for one second more. But I knew neither of those things were going to happen now, so I’d just have to say it to myself: Come on, Iris. This is the best thing that could’ve happened to you. Years from now, you’ll look back and see. Splitting our parents up was something I had to do. For me. For my mother. And in some ways, for you.
