“She will let you,” I say gently. “If you ask that of her.”
I turn to her to make sure, and she nods eagerly. “I will, Father.”
“Do you want him to?” I ask.
“Yes,” she says, her cheeks coloring and her fingers wrapping around the cross she uses as her own form of self-flagellation.
“I don’t fucking want you,” Saint snaps, shoving up from the chair and pacing in agitation. “What’s wrong with you? You’re my sister. And you’re fucking pathetic if you’d let me. I’ve done nothing but disrespect you since the day you got here. If you’d spread your legs for me after the way I’ve treated you, you’re a desperate slut, and I don’t fuck desperate sluts. Especially not my ugly stepsister.”
“Are you sure?” I ask. “You’ve suffered long enough, Saint. You’ve earned her submission, if you choose to accept it. She has given it to you to do with as you see fit. Will you accept this gift from her as penance for the harm she’s caused you?”
Saint wheels on me. “No,” he growls. “I told you. She’s fucking hideous. She dresses like a little girl. She doesn’t even shave her cunt.”
“I want you to be certain before you refuse.” I turn to Mercy. “Show him what he’s turning down. He will have to live with the fact that someone else will accept the gift he didn’t, if he can’t admit the truth, that he wants this as much as you do.”
“Show… Him?” she asks, chewing at her lip in anxiety. “How?”
“Like you showed me,” I say, nodding to her pants. “But without those. Can you do that, lamb? For me?”
Her breath hitches, but after a second, she nods. She stands slowly, stripping off her pants and panties together. She steps out of her fat Santa slippers and slides her bottom back onto the bed.
“Scoot back,” I order. “Put your feet on the edge of the bed and spread your legs.”
She obeys, then hesitantly brings her fingers to her exposed cunt. “Like this, Father?”
“Yes, lamb,” I assure her. “Just like that. Now show your brother how wet you get for him.”
The sense of heady power rises in me, amazement and awe filling me when she obeys without question. After a minute of touching herself for us, her flesh glistens with arousal, and she starts breathing harder, her cheeks pinkening.
“You too,” I tell Saint, unable to tear my gaze from Mercy’s perfect, pink cunt.
Her brother stands beside me, equally transfixed, as he unzips and pulls himself out. He’s already hard, his cock springing free and standing thick and straight. He grips it, jerking himself in rough, angry strokes.
“Doesn’t she look divine?” I ask as her head falls back, her hips moving in slow circles to match her finger as she smears it over her drenched flesh, opening herself, offering herself to him.
“Divinely desperate,” he grunts, jerking harder, his cock stiff in his hand. After only a minute, it throbs out a spurt, then another. It falls in ropey strands to the floor, leaving creamy loops and splatters on the tile.
“Oh,” Mercy cries, her eyes rounding as she watches her brother unload his cum shot while watching her pleasure herself.
“There,” he grunts out. “Now you know how I feel. I already know how you feel. You’d get on the floor and drag your ass in my cum like a dog if it meant you’d get some in your pussy.”
“Would you?” I ask Mercy.
Hurt pools in her blue eyes, but after a second, she bites her lip and nods, looking guilty.
“Show him,” Saint snarls, shoving his dick back into his jeans. “Show him what a pathetic, desperate, horny little slut you are.”
She turns her gaze to mine, imploring.
I nod. “Show me, lamb.”
She hesitates a moment, then slides gingerly from the edge of her bed to the floor. I watch in awe as she lowers herself onto the splatters her brother left, sliding in small circles in it, coating her bottom. The sense of power that swells in me is more than a tide, it’s a tsunami.
“You can do better than that,” Saint taunts. “Show me how much you want me, little sister. Show Father how much you love my cum. Scoop it up and stick it in your dirty cunt. You know you want to.”
Her shoulders shake with sobs, but she smears her fingers in his mess, scooping it up. Trembling globs of white coat her finger, and she sucks in a shuddering breath as she pushes it inside herself. With a mewling cry of surrender, her head falls back. Her hips jerk, bucking, riding her hand. She drives her delicate finger into her hungry cunt over and over, stabbing her brother’s cum into it with startling violence. She goes up on her knees, back arched, and rides out her orgasm with silent sobswracking her body. At last, she collapses into a heap in the smears of Saint’s release that coat her floor, curling into a ball.
“Disgusting,” Saint says, but he sounds gratified. He leans forward and spits, the glob dropping onto her tear-stained cheek before he turns and walks out the door, leaving me alone with the greatest temptation I’ve ever known.
