Tainted

When he first feels the urge, Pietro is ashamed. He shouldn’t want his twin sister like this. Yet, when he watches her grow from a girl to a young woman, he’s mesmerized by the changes. 

He knows that he is also changing, his adolescent body full of tempestuous emotions and impulses. Though, he cannot stop the rush of desire when he looks at his sister. He blames their closeness, and that they once shared a womb. He doesn’t love anyone as much as he loves Wanda, and he knows that will never change.

He wants to remain close, to watch her fair skin develop into curves he longs to caress with his fingers. He wants to touch and taste every bit of her, and as her brother, he wants to possess her knowing his sister would never allow him to do so. He wants to claim her as a man claims a woman in his bed.

Pietro resists the urges, pushing them down deep into his psyche and letting them rot with his other unnatural thoughts. Though sometimes he needs to relieve the pressure, and he feels tremendous shame when he touches himself and thinks of her. Still, she will never know. She won’t look inside his thoughts and see her there, fully exposed and pliant under his heady gaze.

When he reaches into his pants, he grips his hardness, relieving the pressure with gentle strokes. He thinks of only her, and he moans when he imagines them in their bed, his hands finding purchase on her soft, rounded breasts and hips, and delighting in their sin without a care in the world. 

Knowing his sister is sleeping in the room next to him, Pietro curses himself, trying to control his sounds. He does not want to raise her concern, but he has to take care of his desires before he’s unable to sleep that night. He has to do this without her ever knowing.

His pace quickens as he strokes himself, up and down, spreading the sticky wetness that forms at his head. He’s panting heavily, and he whispers her name as he rubs himself faster, feeling the heat quicken over his skin.

“Pietro?” his sister calls out to him by his door. He freezes, his thoughts turning into dread. No, no, he doesn’t want her here!

“It’s fine,” he croaks. “I’m fine. I’m just…”

His door creaks open and she steps inside. He tries to cover himself in his bed, but when he meets her eyes, she realizes what she’s interrupted. His face feels like it’s burning, and he looks away from her piercing gaze.

“I’m sorry,” she says softly. “I did not mean to...I was worried. I thought I heard you crying.”

He inches away as she continues moving toward his bed. She stops at the edge and watches him.

He sputters out. “It’s fine. It’s perfectly natural and…” 

“Do you want me to help?” she asks, and he turns toward her in shock.

“No! You shouldn’t, I mean, Wanda, that’s not…” right, he is about to say, but then she crawls next to him on the bed and curls into him.

“Pietro, we don’t keep things from each other. I don’t want you to suffer,” she says, and she dips her hand under the blankets, searching out his heat. He feels her soft hands rest over his as he grips himself. 

He stares at her, still awestruck to believe this is real. He’s sure he cannot dissuade her at this point. He trembles as her soft fingers push away his hand, and she takes him into her grasp. 

Instead, he pleads with her once more, but he knows he doesn’t want to lose her touch. He wants more than this from her, but his rational mind is screaming for them to stop. “Wanda, you don’t have to do this. Please, I don’t want you to regret this…”

She looks up at him, meeting his panicked eyes with her calmness. “Pietro, brother, I love you. I will never regret anything we share together.”

“I love you, too, Wanda, sister, but you don’t know how much. You don’t know that I think of you…” She places a finger against his lips to silence him. He gapes at her as she leans into him and places her lips against his for a kiss. Her breath is hot against him.

She whispers. “Tell me what you like, brother.”

He lets out a strangled cry as she caresses his cock lovingly. “I...either use your hand or…” He swallows hard, and can’t believe his thoughts are spilling out like this. “Your mouth.”

“Hrmm,” she says, and he watches her as she dips below the blankets. He groans as he feels her wet mouth engulf him, sucking him up, and trailing her tongue down his shaft. Pietro tenses as she continues her ministrations, lapping him up and sucking the head, teasing the slit as she tastes him. 

“Ha…” He lets out a noisy moan and feels the tension heighten in his body as she continues to lick and suck at him. 

He yells out something in Sokovian, and she draws him into her hot mouth as far as she can. He pitches forward like receiving a blow to the head, and he comes in her mouth before he can warn her.

“Wanda, I’m sorry, I’m so sorry…” he says, and he begins to cry.

She draws him into her embrace, and they settle into the bed curled against each other. She kisses his tears away, and he shakes against her, aghast at what they’ve done, and shame for enjoying her touch so much.

“I’m sorry,” he sobs. “I shouldn’t love you like this. I’m sorry I’m so tainted.”

“Shhh,” she says, carding her fingers through his hair to soothe him. She pulls her face to his so she can meet his desperate eyes. “It’s alright, don’t fret, brother.” She kisses his forehead lovingly and adds, “If you are tainted for loving me like this, then I am tainted too.”

She nuzzles her forehead against his, and he lets her draw him into the embrace. His body stills next to hers, and Pietro strangely feels at ease. He hugs her tighter, and he feels sleep wash over him in warm dreams.

He dreams only of her, and he feels a sense of peace knowing that she loves him just the same, no matter how wrong it is.
