“Hold yourself open for his use,” the Master orders gently, placing her hands on her cheeks.
A tremor goes through her body, but she spreads her ass for me. Her hole tightens into a tiny, rosebud ring.
“Oh, loosen up,” I say, spitting into my palm and rubbing it into her crack. “If you want me to stop, just tell me no. Tell me you don’t want it.”
She doesn’t move, but her ass hole unclenches, spreading soft and petal pink like a kiss. I chuckle and line myself up, rubbing the torpedo head of my dick against her quivering hole.
“That’s right, you can’t,” I taunt quietly. “You want your brother’s dick so bad, you’ll take it any way you can get it. Even in your tight little virgin ass.”
When she doesn’t answer, I thrust forward, breaching her untouched entrance in one deep, brutal thrust.
She cries out, her fingers clenching on her ass cheeks, which only spreads them wider. But the ring of muscle around my cock clenches so tight I can’t see straight, strangling my cock in a death grip that makes me lose my mind. I pull out and stab back into her hard and fast, imagining the strings of cum spraying from her sweet lips as she chokes and sobs in pain,trying to catch her breath. I ram into her harder still, wrecking her clenching flesh again with each stroke.
“This is what you wanted, isn’t it, sis?” I taunt, ramming balls deep into her. “If you wanted gentle, you would have picked Angel. You picked me, so now you’re getting what you asked for.”
She nods her big bobble head, and it pisses me off that even now, with her face hidden by a blank mask, I can’t pretend it’s anyone else. It’s Mercy, the girl I’ve always wanted, the girl I never thought I could have. And now she’s mine. I’m going to enjoy every fucking minute of it.
“You’re doing great,” the Master says, sinking onto the altar beside her and stroking her trembling back. “Take your brother’s cock nice and deep, like a good girl.”
“That’s right,” I growl, punching into her ass hole in rough, relentless strokes. “You wanted your brother’s cock, so take it up the ass like the slut you are. I’m going to wreck your ass until it’s as worn out as your pussy and so sore you can’t sit for a week.”
Mercy chokes on a sob, and then I hear her slurping to get the cum back into her mouth.
I hammer into her so hard she slams into the stone, her ass and hips jiggling as I batter her ruthlessly. “You can make it better or worse for yourself by relaxing or tensing up,” I taunt when I feel her squeeze tight in pain again. “It doesn’t matter to me. I don’t give a fuck if you like it or not. It’s what’s happening. You chose this, so you might as well try to enjoy it.”
“Hold yourself open for his sin as long as you’re willing,” the Master says.
But she doesn’t release her grip on her soft flesh, doesn’t push up on the stone, tell me to stop, to leave her alone and never speak to her again. She spreads herself further, arching her back to receive every brutal blow my hips deliver to hers.
I know somewhere in the back of my mind that I should be nicer. I should be thankful that she chose me. That she’s always chosen me, picked me, just like I always picked her from among our stuffed animals when we played as kids. I’ve always wanted her, just as she’s wanted me. I’ve always wanted her exactly as she is, but now that I have her, instead of treasuring her the way I do inside, I’m hiding her away in a mask, pretending she’s a whore like every other girl I’ve fucked.
She’s not, though.
She’s my darling sister, still as pure to me as the day she came home with my parents, as sweet and perfect now as she was then. No amount of other men can ever change that. That is who she is.
I fucking love it, and I hate that I do, hate that I love her. That after all this time, she is still the same soft, submissive, worshipful girl she always was, and that no matter how cruel I am to her, I can’t change that. None of us can. Mercy is the girl she always was, but I’m not the man I once was. She destroyed me, and I fuck her like I want to destroy her back, force her to see that I’m not the brother she idolized, not a man worth loving.
Heath starts dancing around, reciting his own prayer as he watches me demolish her the way he dreamed of doing all those years. I hate that I took this from him, but I don’t stop. I won’t, until I’ve ruined her the way she ruined him.
“Our father, who art in heaven,” Heath says, cackling as he goes on.
“Hollow be thy name
Thy King will cum
—Her will be gone—
In her, as she is our heaven
Get us our lamb daily bred
Forgive us our sin
As we forgive those who trespass against us
Lead us not into temptation
But slam us in balls deep
