"Tell her how good it feels," I order my slut. "Tell her how grateful you are to have my cock in you. How jealous she should be."
"It's a-amazing," Marissa stutters, and I rain hard blows against her ass.
"More!"
"He feels so good," she breathes. "So tight... ahh, fuck!"
The little whore's about to have an orgasm already, and I decide to let her this time. Another opportunity to show June what she's missing. I fuck Marissa hard, and the girls keep their gazes locked the entire time. My cock grows harder and harder with each thrust of my hips, but the real excitement starts when I pull a knife from my boot.
"No," June whispers. "Don't hurt me."
"I told you." I smirk. "Marissa's your whipping girl tonight."
My toy's eyes widen at the sight of the knife. I haven't used it on her before, and I know she's scared, not that I really give a shit about her fear. I run the blade along her spine, nicking her here and there, watching thick droplets of blood form on the surface of her tanned skin. God, I'm so fucking turned on I could come right now. Marissa seems to share the sentiment, and another grateful orgasm rips through her body as I punish her with my dick.
"I'm going to come in her," I tell June darkly. "And you're going to beg me to do it."
"No," my stepsister hisses.
"No?" I grin. "Every time you say no to me, Marissa here gets a pretty little cut to add to her collection. Now I'd really rethink that bratty side of yours if I were you."
June pales as I wave the knife in front of her face. "So, what'll it be? Another no, or will you beg like a good fucking girl for me?"
"P-Please," she manages.
"Pathetic." I nick Marissa again, and she cries out from the sharp pain. "I suggest you try fucking harder, June."
"Please come inside her." Something's broken inside my little sis now. Her eyes stare at me blankly. It's as if she isn't here at all, having given in to her fate completely. "Please, Parker."
I would usually scold her, tell her to call me by my new name, but not this time. My old name feels sinful, forbidden on June's lips. And I want fucking more. I don't hesitate to tell her as much.
"Keep begging. Keep fucking asking for it if you don't want your new friend to get hurt."
"Please, I..." June blinks away the tears from her eyes. "Please, come inside her. Please. Fill her up. Give it to her. Do it."
Her words are bringing me closer and closer to an orgasm, and I feel my cock throb with unspilled seed. I groan, knowing I'm getting closer and closer to the release I've been craving all fucking day. "You want it, June? Ask again. Ask like you really fucking mean it. Or else..."
"Please!" She's desperate now, whether for her own sake or Marissa's, I don't know or particularly care about. "Come in her, Parker! Fill her with your cum!"
I groan. My balls are heavy, my dick is fucking throbbing, and I stare into June's eyes as I unload in my toy's cunt, wishing it were my little sis. But I need to bide my time. After all, I have plenty.
Marissa's body sways as I fill her up, and I pull my still-throbbing cock from her hole and show it off to June with a wicked smirk. "Clean it."
She turns her head to the side in disgust. "No."
"What did I fucking say about that word, Junebug? I'm going to beat it out of your fucking vocabulary if I have to. Now lick."
Reluctantly, she opens her mouth, and I push my tip in her mouth, groaning as her tongue swirls around my cockhead. Goddamn, she's good at this. Jealousy twists my stomach into knots as I start to fuck her mouth, making her choke. I could come again right now, but I hold back, waiting until my stepsister has made my dick spotless. Then I pull out and approach Marissa, who's lying, dripping on the floor. I reach between her legs and scoop out the load I've put in her pussy while June watches with wide eyes.
"See this, June? Look at how big my load was... That's because of you." I approach her, cupping my palms with the cum in them. "This is going in you, June."
"No, I—" She stops herself just in time, and I grin at her. I'm still holding the knife in my other hand, and I'm more than willing to use it. In fact, I'm just looking for an excuse to carve either of the girls up. I kneel next to my stepsister, spreading her legs and glancing at her panties.
They're fucking wet.
My eyes meet with hers, burning with surprise. Her own gaze is filled with shame, and she won't look at me. I feel sorry for her then. This pretty girl is so lost in her own idea of what's right that she can't even admit all of this is a fucking turn-on.
