For a long moment, the only sounds were their ragged breaths and the soft, wet drip of spent fluids onto the mahogany. Adunbi lay, utterly spent, his softening cock still sheathed inside Osa’s clenching heat. She was a trembling, sweaty weight on top of him, her back slick against his chest. Quivina finally pulled back, her face a mask of satisfied, wicked triumph.
“Alright, my gorgeous deviants, ” Quivina said, her voice husky but practical. She gave Osa’s flank a gentle slap. “Up. Let’s get cleaned up before we stick to this desk permanently.”
She moved with a fluid grace, sliding off the desk and padding to a small adjoining bathroom. The sound of running water followed. Osa stirred, a soft whimper escaping her as she carefully lifted herself off Adunbi’s deflating length. A thick, creamy rush of semen spilled from her onto his stomach and the wood beneath them, a shocking, tangible proof of what they’d done. The air smelled of sex, salt, and musk.
Adunbi pushed himself up on his elbows, watching as his sister�his sister�swung her long legs over the side of the desk. Her movements were stiff, unsteady. The sight of her, utterly ravaged, her full ass and thighs glistening with their shared mess, sent a dull throb through his exhausted body that had no right being there.
Quivina returned with a bundle of damp, warm washcloths. She handed one to Osa and began to gently wipe Adunbi’s stomach and chest herself, her touch oddly tender amidst the carnage. The cloth was rough against his sensitive skin.
“There, ” Quivina murmured, cleaning him with efficient strokes. “Better.”
They dressed in a heavy, shared silence. Fabric rustled. Zippers closed. The simple acts felt surreal, like astronauts donning suits after a walk on a forbidden planet. Osa slipped her crimson dress back over her head, the silk clinging to her damp skin. Quivina stepped into her sleek black dress, becoming the elegant stranger from the party once more. Adunbi pulled on his boxers and pants, the confinement of the fabric feeling alien after such profound, wet freedom.
Quivina led them to a small, plush sitting area in a corner of the large room, away from the evidence-laden desk. She sank into a deep armchair, crossing her legs. Osa perched on the edge of a loveseat, looking fragile. Adunbi remained standing, leaning against the wall, his arms crossed over his still-heaving chest.
The silence stretched, thick with unspoken words.
It was Quivina who broke it, her dark eyes glinting. “So. How do you feel?”
Osa’s gaze flickered from the floor to her brother, then back. A faint, incredulous smile touched her lips. “Hollowed out. Stuffed full. I don’t know.” She shifted, wincing slightly. “Sore. In... a good way.”
Adunbi grunted in agreement. It was the understatement of a lifetime.
Quivina’s smile widened. “Good. That’s how it should feel.” She leaned forward, her elbows on her knees. “Now for the interesting part. The implications.”
The word hung between them, cold and sharp. Implications.
Osa swallowed. “You mean... the baby talk. During.”
“I mean the baby reality, ” Quivina corrected, her tone losing none of its sensual warmth even as she spoke the heavy truth. “Adunbi came inside you, Osa. Three times. Three massive, deep, fucking loads. We’re not talking about a little spill here. We’re talking about a flood.” Her eyes locked onto Osa’s. “Your cervix was practically bathing in it by the end. You felt that warmth, that weight, pooling inside you, didn’t you? That’s not just cum. That’s potential. That’s life.”
Adunbi felt a chill that had nothing to do with the room’s temperature. He’d been lost in the primal act, in the taboo thrill, in the sheer physicality of it. Quivina’s words dragged the biological stakes into the stark light.
“It was... a lot, ” Osa whispered, her hand drifting unconsciously to her lower abdomen.
“It was a fucking ocean, ” Quivina said, a thread of awe in her voice. “Think about it. Right now, inside you, millions of his little swimmers are making their way through all that warm, perfect fluid. Your body is ripe for it. You were ovulating, weren’t you? You had that glow.”
Osa’s eyes widened. A slight, almost imperceptible nod.
Quivina let out a soft, triumphant breath. “I knew it. The timing... it’s too perfect. It’s fate.” She turned her gaze to Adunbi. “Do you understand what you did, Adu? You didn’t just fuck your sister. You very, very likely impregnated her.”
The word was a physical blow. Impregnated. Adunbi pushed off the wall, running a hand over his face. The image flooded his mind: not of the passionate fucking, but of the aftermath. That thick, white torrent he felt leaving him, surging into her deepest channel. The way her womb had seemed to pull at him, drawing his essence in. It wasn’t just pleasure; it was a biological transfer. A seeding.
“You wanted this, ” he said to Quivina, his voice rough. “You orchestrated it. The dirty talk... ‘breed her’... you were making it real.”
“I was making it honest, ” she countered, her chin lifting. “I don’t play games with pretend stakes. The risk is the thrill. The potential consequence is the ultimate taboo. A child. A living, breathing symbol of this...” She gestured between him and Osa. “Of this connection. Your blood, mixed and multiplied.”
Osa was shaking her head slowly, but there was no denial in it. It was a dazed processing. “A baby. My brother’s baby.” She said it aloud, testing the shape of the words. They didn’t sound horrifying. They sounded... inevitable. A deep, secret part of her, the part that had ached for him for years, clenched with a fierce, terrifying possessiveness. His child. Growing inside me.
“What if she is?” Adunbi asked, the practical part of his mind clawing for purchase. “What then?”
Quivina leaned back, a serene queen on her throne. “Then we have a very interesting nine months ahead. And a beautiful baby after that.” She looked between them, her expression softening into something genuine. “This wasn’t an accident. It was a choice. All of our choices. You both walked in here. You both took what you wanted. This...” she gestured at Osa’s stomach, “...is just the most profound possible outcome. The universe saying yes.”
The room seemed to pulse. Adunbi looked at Osa. Really looked at her. The woman he’d just fucked into a sobbing, blissful wreck. His sister. Her hand was still splayed protectively over her womb, the womb he’d just filled. A possessive heat, entirely different from the lust of before, kindled in his gut. The idea of his seed taking root in her fertile soil... it was wrong, it was illegal, it was the deepest sin.
It was also the most powerful thing he’d ever felt.
Osa met his gaze. Her dark eyes were no longer clouded with pleasure, but with a sharp, clear understanding. And a question. She saw the same possessive heat in his eyes.
“You’re not... upset?” she breathed.
“Upset?” Adunbi echoed. He let out a short, humorless laugh. “I’m terrified. I’m... I don’t know what I am.” He took a step toward her. “But the thought of you carrying my child...” He couldn’t finish. The words were too immense.
Quivina watched them, a slow smile spreading. “See? The fucking was just the beginning. The real connection starts now. With this.” She stood up, smoothing her dress. “I’m going to get us some water. You two... talk.” She glided out, leaving the heavy, charged silence behind.
Alone, the space between them felt electric. Osa didn’t move from the loveseat. Adunbi stood a few feet away, his mind reeling.
“Do you really think...?” Osa started, her voice small.
“After what just happened?” Adunbi said. “With the amount that came out of me? Yes. I think it’s a real possibility.” He took another step closer. The scent of her, of them, still clung to her. “How do you feel about that possibility?”
Osa looked down at her own lap, then back up at him. A single tear traced a path through the remnants of her composure, but her voice was steady, strong. “When you were inside me... at the end... it felt like more than just coming. It felt like you were... claiming something. Planting a flag.” She took a shaky breath. “A part of me wants that flag to grow. Is that insane?”
Adunbi closed the final distance between them. He didn’t sit. He loomed over her, his tall frame casting her in shadow. He reached out, his thumb brushing away that single tear. His touch was gentle, but his expression was fierce.
“Then we’re both insane, ” he said, his voice a low rumble.
