Candi presses a finger to your lips, silencing you. "Shh. Come here." She scooches over and makes space for you on the bed before gently pulling you down, spooning you from behind, hands running up and down your chest. It makes you feel strange. "You're so brave, fighting for me like that. I…thank you."
The genuine relief in her voice is inspiring. You relax a little in her grip. "I wanted to beat him. I…I hit him, but…" you couldn't finish it. He's still too strong for you.
Candi presses her chest against your back and you feel her small breasts on you. "Ralphie told me about…that girl," she says. She does not say Annie's name but she doesn't need to. The distaste in her voice is enough.
You tense up a little but she keeps rubbing you, soothing you.
"I"m sorry, Kyle." She kisses the back of your neck, making you shiver slightly.
You don't say anything.
Candi falls silent. You feel her thinking, worrying. Her hands go lower, rubbing your abdomen. Her fingers brush across the waistband of your jeans. "I don't want you to worry about that anymore. You don't need her." Her hand goes lower still and you stiffen up. Ha. Ha.
"Candi, what–"
She shushes gently in your ear, giving you goosebumps. "Let me do something nice for you." Now both her hands are on your jeans, feeling you, gripping gently. "I want to."
Her tone makes you forget your pain, forget what you saw in the barn, forget the bruising around your neck. You feel the blood rushing in your head, your mouth is dry suddenly.
You want it. There's no question in your mind that you want it, especially now with her hand gently squeezing you. Fuck, this is wrong. It's so fucked up, but… "Is this what you really want?" You have enough self-control to ask. After what Dad's done to her you want to check with her. You still care about her, more than anyone else. If you don't have her then you have no one.
Candi chuckles softly in your ear and squeezes you tighter, her hand running up and down your bulge. "Yeah." She finds the zipper of your fly and starts pulling it down. "You haven't ever done this before, right?" There's no judgement, she's curious.
You shake your head slightly.
"It's okay," she says. "I'll show you. You don't need to be gentle." She hops off the bed and slides her panties off and pulls her shirt over her head so now she stands completely naked before you.
You look. You don't even have to pretend not to want to.
"I just have two rules." She comes to kneel between your legs on the bed. "Only in my butt, and you can't leave any marks. Dad can't ever find out." She gives you a serious look, making sure you understand, waiting for you to agree.
"Okay," you whisper back, feeling light headed.
Candi smiles at you and starts tugging your jeans down. "This will feel good for you. You'll like it."
Your heart is racing, thundering in your chest as your erection springs free, proud and eager, unbothered by your sibling relationship. It's not picky. Soft, smooth flesh, pale curves, and an inviting touch are all it needs.
"Wow," Candi says, the reaction every guy wants. "I didn't know you'd be so… big." She smiles playfully and then starts stroking you with her hand.
You swallow, mouth dry, afraid to speak. You want to tell her to stop. You want to tell her to keep going. You're throbbing in her grip, already starting to leak.
She tightens her hand slightly, biting her lip as she sees precum bead on the tip of your dick. She strokes faster, pumping you eagerly. "Feel good?"
You nod, still not trusting words.
"Ready?"
You nod again. You're a little surprised to see apprehension on your sister's face. It's only a hint, like a cloud passing briefly over the sun. She's unsure, worried, nervous, afraid. But she pushes through. Candi spits on your dick, massaging her saliva across your length with her hand. Then she does it again. Her eyes flick up to yours, looking a little embarrassed that you had to see that.
You don't feel any embarrassment. It just feels good.
She stands up suddenly. It's over. Reason and shame overcame whatever ill-advised generosity she intended to show her brother. But then she's straddling you, pushing you gently down onto your back as she squats on her tiptoes over you, one hand holding your cock still and upright, the other on your chest for support. "I've never done it like this," she whispers, voice wavering with nervousness. "So… I'm just going to do my best." You feel your thick head snug against her tight backdoor.
"Candi, you don't have to–"
She starts lowering herself with a grimace. "Mmh…" Her grip tightens on you again, so tight it's almost painful. She gives you a few strokes, either accommodating you or trying to psyche herself up, you're not sure. "Shit," she whispers, lowering herself again.
You grip her thighs, fingers digging into her. It's partly reassurance for her, partly to hold on as you feel her asshole start to relax enough for you to push into her.
"Oh, fuck," Candi gasps as you slip up her butt. "Fuck!" She doubles over, hair hanging over your face, breathing hard. "Shit that burns…"
"We can stop," you say, though you don't want to.
Her eyes flash with determination and she shakes her head, adjusting herself slightly and then lowering onto you again with a pained moan. "God damn." She's got enough of you inside her now that she lets go of your base, putting both hands on your chest for support as she starts to slowly bounce up and down on you. It's only an inch or so. But it's an inch of pain for her.
She keeps her teeth clenched, staring down into your eyes as she works, riding slowly, working further each time. "Mmmm," she lets out a tense moan and her eyes water as she gets more than half of you into her. "Does it feel good?" she asks, her voice wavering with discomfort. The insecurity in her tone is unmistakable.
It feels amazing. "Yes." It feels like heaven as you fuck your sister's snug ass. You could have never imagined how good it would feel. How right.
Her breasts jiggle slightly as she rides you, bouncing with her movements. It's not smooth, it's mechanical, forced. Candi is imitating what she's seen in porn, maybe imitating what she's done with Dad, but she's doing it for you. Doing her best.
"Oh," she says. It's the first sound that's remotely like pleasure that comes from her. But it's enough to set you pulsing. She's tight. So incredibly tight. You can feel her inner muscles tensing, clenching desperately around you, squeezing you, milking you. Her relentless movement is steadily coaxing you toward an orgasm. Or maybe not so steady. Feels like you're sprinting there.
You feel panic rise within you like a bubble as realization hits. "Sh-shit." You're going to cum. You're going to cum in your sister's ass. What the fuck led you to this point? It's not like she can get pregnant or anything but… you really shouldn't cum in your sister's ass. Right? "C-Candi," you whisper urgently, gripping her legs, trying to make her slow down. "I can't. I'm going to…" you can't say it.
She looks surprised at first and then… and then she smiles, increasing her pace despite the tears rolling down her cheeks. "It's okay," she says, voice tight with discomfort. "Do it inside. I want to feel it."
You shouldn't. You really really shouldn't. Once you do this, there's no going back. It's done and can't be undone. After this moment you'll know exactly what it feels like to cum inside your sister. But you can't stop either. It feels too good. It's just too much. She's so tight and hot and desperate. Her soft noises of discomfort almost sound like moans of pleasure. You can almost imagine she likes this. Almost.
"Cum for me, Kyle," she whispers. "Cum in me."
You let go of everything. You let go and throw yourself into the void. It still takes a moment for you to finish, her tense sphincter gripping your shaft and milking you to orgasm. You moan loud and long, louder than you should, as you climax up your sister's tight ass.
She gasps, feeling you pulsing inside her, and quickens her pace, riding you erratically as you dump your hot, sticky sperm into her rectum.
"Ah… ah God, God…" you whisper, a broken prayer to a dead deity while you fire potent sperm into your sister's guts. Heaven is real, just for a handful of heartbeats as everything is washed away in an orgasmic haze.
Candi whines, sweat beading down her chest as she forces herself to keep riding you, working every drop out. Finally she can't take it any more. "A-are you done?" she says.
You're lost in bliss and can only nod.
She stops bouncing and holds still, her exhausted legs trembling slightly before she slowly lifts herself off of you, crying out when your cock slips free of her butt along with a trickle of semen. You both stare at your shared crime, the product of your incestuous coupling.
When she looks back at you, Candi is smiling. "It's a lot, right?"
"Yeah."
She carefully lays down beside you, resting her head on your chest. "You can shower after me," she says.
You say nothing.
"Was it good?" she asks.
"Yeah," you say. You don't bother to ask how it was for her. You know she'd say it doesn't matter.
"Good." She nuzzles your neck. There's a long pause, the two of you both breathing in the dark, the reality of what you've done crushing inexorably down on you, like the blade of a guillotine dropping. This moment is now forever a part of your life. Inescapable. "Let's do it again tomorrow," she says.
You smile in the dark, feeling a strange relief in shedding your guilt and apprehension. It's like tearing through an old skin and being born a new. "Yeah," you say. "Let's."
