The room was dimly lit, only the bedside lamp casting a warm, contained glow over the bed. Ylva had sat down on the edge of the mattress, her legs slightly apart, her trousers already pushed down to her ankles. Her cock rested heavy against her thigh, still half-soft, but pulsing with a slow rhythm that betrayed what was coming. Summer knelt between them, her hands resting on her aunt’s knees, fingers tense, as if she didn’t quite know what to do with them.
The girl was fourteen and looked even younger in that moment. Her hair fell across her face in messy strands, and her eyes, wide open, wouldn’t leave the member in front of her. She said nothing. She only breathed through her mouth, small sips of air that could be heard in the silence.
Ylva watched her. Thirty-seven years old, and she had never felt anything as contradictory as this. Her niece. Her brother’s daughter. That quiet, obedient, untouched girl. And now she was here, cheeks flushed and lips parted, staring at her aunt’s cock as if it were something she didn’t fully understand but had already claimed her.
“Come closer” Ylva said, her voice low, almost hoarse. It wasn’t a harsh order. It sounded more like a tired suggestion, as if she herself were fighting the urgency rising in her belly.
Summer shifted forward on her knees. Her hands moved a little higher along Ylva’s thighs, cold and trembling. Her fingers brushed the warm skin and stopped just short of touching. Ylva felt the contrast: those small, cold hands against the heat that was already hardening between her legs.
“You can touch it” Ylva murmured. “It doesn’t bite.”
Summer swallowed. Her fingers closed around the shaft with clumsy delicacy, as if she were afraid of breaking something. The cock responded immediately, thickening in her hand, the skin stretching, veins becoming more defined. Ylva exhaled slowly, eyes half-closed, watching how her niece’s innocence made everything feel dirtier than it already was.
Summer leaned in. Her lips brushed the tip first, a timid, almost experimental kiss. Then she opened her mouth and took the head between her lips. It was hot, soft, and had a slightly salty taste that made her frown for a second, but she didn’t pull away. She tried to take more, her cheeks hollowing, and when she reached the halfway point she stopped, her eyes watering from the effort. She couldn’t go further. Her throat closed in a small spasm and she had to pull back, gasping through her nose, a thin string of saliva connecting her lips to the now fully hard cock.
Ylva felt a strong throb. Seeing her like this — mouth swollen, eyes confused, trying to take it again — was obscenely perfect. Her niece. The same girl who, two hours earlier, had been sitting on the couch with a math book in her hands, answering her tutor’s questions in a quiet voice.
“Slower” Ylva said, and her hand settled on the back of Summer’s neck, not pushing, just holding. “You don’t have to swallow it all. Just… suck it.”
Summer nodded almost imperceptibly. She tried again. This time she licked the underside, her tongue flat and clumsy, tracing the thick vein that pulsed there. Then she took it back into her mouth, deeper than before, and when it reached the back of her throat again, she squeezed her eyes shut. Her hands gripped Ylva’s thighs, fingers digging in a little.
Ylva couldn’t stop watching. Every time Summer failed, every time she pulled back with shiny lips and ragged breath, her cock grew harder. The head glistened with saliva and precum. It was too much. Seeing that innocent face struggling to please her, doing something she had clearly never done before, stirred a mix of tenderness and something much darker inside her.
“Fuck, Summer…” Ylva whispered, and her voice came out dirtier than she intended. “Look at you. Such a good girl… and here you are, with your aunt’s cock in your mouth.”
Summer glanced up for a second. Her eyes were glassy, not exactly from pleasure, but from concentration and something she couldn’t name. She didn’t answer. She simply lowered her head again, trying once more, slower, more careful. Her lips stretched around the thickness, and when she managed to keep it inside a little longer, Ylva felt her balls tighten.
Ylva’s hands slid down to Summer’s ass. Over the skirt at first, then underneath, seeking skin. Her fingers were cold compared to the heat radiating from the girl’s body. She squeezed gently, feeling the firm, young flesh, and Summer let out a small, muffled sound around her cock.
“That’s it…” Ylva murmured. “Suck it properly. All the milk I’m going to give you is for you.”
Summer didn’t fully understand. It showed in the way she frowned when she swallowed the precum that reached her tongue. But she kept going. She kept going because it was Ylva asking, because ever since she had stepped into that room everything had felt strange and hot and necessary in a way she couldn’t explain.
Ylva began to move her hips very slowly, almost without realizing it. Short, controlled thrusts that made her cock slide in and out of that inexperienced mouth. The wet sounds filled the room, along with Summer’s uneven breathing.
When she felt she couldn’t hold back any longer, Ylva tightened her fingers on her niece’s ass and let out a low groan.
“Ah... I’m going to come… don’t pull away.”
Summer didn’t pull away. Her eyes widened a little when she felt the first hot spurt hit the back of her throat. She frowned, confused, as if she hadn’t expected that amount, that thick, warm consistency. She swallowed on instinct, but not everything. A little escaped from the corner of her lips, sliding down her chin in a white trickle.
Ylva watched her while she came, pleasure mixing with a guilt that wasn’t strong enough to stop her. Her niece, with her mouth full of her semen, trying to swallow it all even though she clearly didn’t know exactly what it was or why it tasted like that. And still she did it. She did it with that same adorable, obscene expression, frowning, licking what had escaped, wasting almost nothing.
When Ylva finished, still breathing hard, Summer stayed there on her knees, breathing through her nose, lips swollen and shiny. She wiped the back of her hand across her mouth, but not with disgust. Only with that innocent curiosity, as if she were processing something new.
Ylva looked at her for a long moment. Her hand still on the back of her neck, gently stroking her hair.
“Come here” she said at last, her voice softer now.
Summer stood up on shaky legs. She sat on her aunt’s lap, her skirt still hiked up and her panties slightly damp from her own excitement that she didn’t fully understand. Ylva pulled her against her chest, feeling the girl’s heart beating fast against hers.
They didn’t say anything for a moment. Only the silence, heavy with everything that hadn’t been said yet.
Ylva ran her fingers down Summer’s back, slowly lowering until she squeezed that small, firm ass again. Her cock, still half-hard, rested between them, brushing against the girl’s belly.
“We’re not finished yet” Ylva murmured against her hair. “Do you want me to show you the rest?”
Summer didn’t answer with words. She simply hid her face in her aunt’s neck, breathing fast, and nodded very slightly.
Ylva’s hand moved lower, sliding between her legs, feeling the wet heat through the thin fabric of the panties. Summer tensed, but didn’t pull away.
Ylva smiled faintly, a contained, almost sad smile.
“Good girl.”
Summer stayed still against Ylva’s chest, her heart pounding so hard it felt like it might push its way out of her throat. The fabric of her aunt’s shirt smelled of detergent and something warmer—adult skin that had lived more years than Summer could imagine. Her fingers clutched the edge of that shirt as if it were the only thing keeping her anchored to the real world.
Ylva felt every one of Summer’s breaths against her neck, short and warm. She still had one hand on the girl’s back, tracing slow circles, while the other rested on her hip, fingers brushing the edge of her panties. Her cock, no longer fully hard but still heavy and sensitive, lay trapped between their bodies, leaving a damp trail on Summer’s flat stomach where semen and saliva had mixed.
“Breathe” Ylva murmured, her voice low, almost a whisper that vibrated against Summer’s ear.
Summer swallowed. She could still taste something strange in her mouth—thick and slightly salty—and every time she swallowed she remembered what she had just done. She didn’t know if she liked it or if she simply liked it because it was Ylva’s. Everything was new. Everything was too much. But she didn’t want to leave. She didn’t want that heat rising in her stomach to disappear.
Ylva slid her hand lower, under the skirt, until her fingers touched the damp fabric of the panties. Summer tensed immediately, a small flinch that pressed her body closer to her aunt’s.
“You’re wet.” Ylva said, without judgment, simply stating a fact. Her thumb brushed the center of that wetness with deliberate slowness.
She slipped her fingers under the fabric, pulling it aside. Summer’s skin was soft, hot, completely smooth because she had never imagined anyone would see her there. When Ylva’s middle finger brushed the outer lips, Summer let out a small, choked sound—neither a moan nor a protest. Just surprise.
Ylva didn’t push inside right away. She stayed at the entrance, feeling how the wetness gathered against her fingertip, how her niece’s body reacted even while her mind was still trying to process everything. She moved her finger in slow, gentle circles, grazing the swollen clit without pressing too hard. Summer’s breathing quickened, her hips shifting just a little—an instinct she didn’t even know she had.
“Like that…” Ylva whispered against her hair.
Summer squeezed her eyes shut. She could feel Ylva’s breasts pressing against her own, fuller and heavier, and for a second she wondered if hers would ever be like that. Her aunt’s hand was skilled, patient, and every caress made something inside her tighten more and more. Her fingers dug into Ylva’s shirt, wrinkling the fabric.
Ylva felt her cock hardening again between them, pressing against Summer’s stomach. The contrast was brutal: her niece so small, so inexperienced, and her at thirty-seven, with a cock that was already throbbing with the need to be back inside that mouth or, better yet, inside the virgin pussy that was soaking her fingers.
“I want you to take off your skirt,” Ylva said suddenly, her voice rougher. “And your panties. Let them drop.”
Summer hesitated for only a second. She climbed off her aunt’s lap with shaky legs, turning her back to her. She unzipped the skirt and let it fall to the floor. Then, with clumsy hands, she hooked her thumbs into her panties and slid them down too. When she turned around, she was completely exposed from the waist down, the skirt a small pile at her feet. Her slim legs, the pale triangle between them, everything glistening slightly from the wetness Ylva had drawn out.
Ylva looked her up and down. Her cock was fully hard again, curving upward, the head swollen and shiny. She leaned back a little on the bed, supporting herself on her elbows.
“Come here. Sit on me.”
Summer approached. She climbed onto the mattress carefully, one knee on each side of Ylva’s hips. When she sat down, the cock was trapped between their bodies, the thick shaft hot against her stomach and her pussy. Summer looked down, confused again. She didn’t understand how something so big was going to fit there.
Ylva took her own cock in one hand and tilted it back, brushing the wet entrance of Summer with the tip. The contact made both of them sigh at the same time.
“Just a little,” Ylva said. “At first, only the tip. If it hurts, tell me.”
Summer nodded, biting her lower lip. She placed her hands on her aunt’s shoulders and lowered herself slowly. The tip of the head pushed against her, opening her millimeter by millimeter. It was much bigger than she had imagined. She felt a strange pressure, a stretching that burned a little, but also a strange pleasure that climbed up her spine.
Ylva clenched her teeth. The tight heat of Summer was almost unbearable. Her virgin niece, so narrow it felt like she might split her in two. Only the head had gone in when Summer stopped, breathing hard, eyes squeezed shut.
"Mmh! hurts…” she whispered, her voice small.
“Shh. Stay still. Breathe.”
Ylva didn’t push. She only moved her hips in very gentle circles, letting the head slide in and out just a fraction, coating itself with Summer’s wetness. One hand rose to the girl’s chest, over the blouse, gently squeezing one of the small, firm breasts. The nipple hardened under the fabric and Summer let out a muffled moan.
Little by little, Summer lowered herself a bit more. Two centimeters. Three. She felt her body opening for Ylva, felt her aunt’s cock filling her in a way she had never imagined. Tears pricked at her eyes, but they weren’t only from pain. It was something deeper, something that made her want to keep going down even if it made breathing difficult.
Ylva watched her with half-lidded eyes. Seeing her cock slowly disappearing inside that innocent girl, seeing Summer’s brow furrow every time she sank a little lower, sent a wave of pleasure through her so intense she had to hold back from thrusting all the way in.
“You’re so tight…” she murmured, almost to herself. “My good girl… swallowing your aunt’s cock.”
Summer reached halfway and stopped again, panting. Her stomach rose and fell quickly. She could feel every vein, every throb inside her. It was too much and at the same time not enough.
Ylva lifted a hand and brushed the hair away from Summer’s face with a tenderness that clashed with what was happening between their legs.
“Look at me,” she said softly.
Summer opened her eyes. They were bright, confused, filled with something she couldn’t name.
Ylva smiled faintly, a contained, almost protective smile.
“Now I’m going to move a little. Just a little. Okay?”
Summer nodded.
Ylva began to lift her hips with short, controlled movements, pushing barely inside that virgin heat. Each time she went a little deeper, Summer let out a small sound, somewhere between surprise and pleasure. Her hands gripped Ylva’s shoulders, knuckles white.
Ylva’s cock throbbed inside her, leaking more precum that helped the slide become a little easier. She felt her balls tighten, full again, aching to empty inside that narrowness that wrapped around her like a hot glove.
Summer lowered herself a little more, almost without realizing, and suddenly something gave way inside her. A sharp, brief pain that made her gasp and dig her nails into Ylva’s shoulders. But then came relief, and a new, deeper sensation that made her open her mouth in a silent moan.
Ylva stayed still, letting her niece adjust. Her hand stayed on Summer’s breast, the thumb brushing the hardened nipple through the blouse.
“It’s done” she whispered. “You’re almost completely full of me.”
Summer breathed through her mouth, staring at the place where their bodies joined. Only a little was left. Just a little more and her aunt would be all the way inside.
Ylva felt the exact moment when Summer’s body relaxed a fraction more. Then she pushed upward, slow but firm, until their hips met and the cock was buried to the hilt.
Summer let out a choked sound, half moan, half sob. Her eyes widened, locked on Ylva’s. She felt the cock pulsing inside her, touching places she hadn’t even known existed. It was too big, too full, but at the same time it was exactly what her body was asking for without her understanding it.
Ylva pulled her close against her chest, holding her still, letting her get used to the thickness.
“Good girl.” she murmured against her hair. “Such a good girl.”
And they stayed like that for a moment, joined, breathing in the same rhythm, while Ylva’s cock throbbed inside Summer, ready to start moving for real.
Ylva’s hand slid down to her niece’s ass again, squeezing gently, spreading the cheeks a little so she could feel better how her cock was completely sunk into that virgin pussy that had just stopped being one.
Summer hid her face in her aunt’s neck again, trembling, and whispered something so quietly that Ylva almost didn’t hear it.
“Mph…it hurts… b-but… don’t stop.”
Ylva closed her eyes, feeling a wave of something that wasn’t only lust. She kissed Summer’s temple and began to move her hips very slowly, pulling out just a couple of centimeters and sliding back in, setting a slow, deep rhythm that made every thrust feel like both a promise and an invasion at the same time.
The wet sound of their bodies coming together filled the room again, more intimate now, more real.
And Summer, with her eyes closed and her body trembling, let herself be carried away for the first time in her life.
Summer clung to Ylva’s shoulders as if the world would vanish if she let go. Each slow roll of her aunt’s hips made the thick cock slide a little deeper, then withdraw just enough, only to fill her again. The stretch no longer burned as sharply, but it remained a constant, heavy pressure that stole her breath. She felt every throb inside her, every thick vein dragging along her inner walls, and it made her tremble uncontrollably.
Ylva kept the rhythm deliberately slow. She didn’t want to break her. Not yet. Her hands rested on Summer’s hips, guiding her with gentle pressure, lifting and lowering her just a few inches at a time. The cock moved in and out with a low, wet sound, almost discreet, but impossible to ignore in the quiet room. The swollen head nudged something deep each time it bottomed out, and Summer let out a small, choked gasp that escaped without permission.
“You’re so tight…” Ylva murmured against her ear, her voice rough but held back. “Like you never want to let me go.”
Summer didn’t answer with words. She only dug her fingers harder into her aunt’s shoulders, knuckles white. Her mind was a whirl: this wasn’t like the books she read in secret, nor like the vague explanations she had overheard once or twice. This was real. Ylva’s cock was inside her, moving, opening her, and her body was answering in a way that embarrassed and excited her at the same time. She felt her own wetness sliding down the thick shaft, easing every thrust, and it made her feel dirty in a way she didn’t fully understand.
Ylva lifted one hand and brushed the hair from Summer’s face again. She wanted to see her eyes. She wanted to see that mix of confusion and pleasure that made her niece look even more innocent. When Summer opened her eyelids, her pupils were blown wide, lips parted. Ylva leaned in and kissed her mouth, slow and deep, tasting saliva and leftover semen. Summer responded clumsily, copying what she felt, her tongue hesitant but curious.
While they kissed, Ylva began to move her hips with a little more force. Not fast thrusts, but deeper, more intentional ones. She pulled back almost all the way and sank in to the hilt again, feeling Summer’s pussy clench around her each time. Her balls tapped softly against the girl’s ass with every motion, a constant reminder of what was happening.
Summer broke the kiss with a gasp. Her forehead dropped against Ylva’s, breathing into her mouth.
“It feels… weird…” she whispered, voice broken.
“You’re full of me” Ylva answered, her fingers pressing a little harder into Summer’s hips. “All of me inside you. Do you like it?”
Summer hesitated. She wasn’t sure “like” was the right word. It still hurt a little, but there was also a spreading heat from her belly down to her legs, making her toes curl. She nodded, the movement tiny, and that was enough for Ylva.
Ylva shifted the angle slightly, pushing upward with more purpose. The head rubbed that sensitive spot inside Summer over and over, and the girl let out a louder moan, surprised. Her hips moved on instinct, dropping to meet the next thrust. She wasn’t conscious of what she was doing; she was simply chasing the pleasure that was building.
“That’s it…” Ylva said, her voice lower, dirtier. “It's like you were born for this... So good..."
The word made Summer blush violently, but she didn’t stop. Her movements grew clumsier, more urgent. She rose and fell, trying to find that friction again. Her small breasts rose and fell under her blouse, nipples hard and rubbing against the fabric. Ylva slipped a hand underneath, lifting the garment, and took one directly. The nipple stiffened even more between her fingers, and she pinched it gently, tugging just a little.
Summer arched her back, a choked sound escaping her throat. Pleasure mixed with discomfort, with the feeling of being used by someone who had known her forever. It made her feel guilty and, at the same time, wetter.
Ylva felt her own arousal rising fast. The cock throbbed inside that tight heat, leaking more precum that mixed with Summer’s juices. Her balls were heavy again, full, ready. She knew she wasn’t going to last much longer like this.
“Summer…” she murmured, and her free hand dropped to the girl’s clit, circling it quickly but softly. “I want to come inside you. Will you let me?”
Summer’s eyes flew open. She didn’t fully understand what that meant, but the urgency in Ylva’s tone made her nod again. She didn’t want it to stop. She wanted to feel more of whatever this was doing to her.
Ylva picked up the pace just a little. Her thrusts became deeper, firmer. The hand on Summer’s clit didn’t stop, and the girl started panting louder, sounds spilling out unchecked. Her body tightened around the cock, small spasms that made Ylva growl under her breath.
“Fuck… you’re squeezing me so hard…” Ylva said through gritted teeth. “You’re going to pull it all out of me.”
Summer couldn’t think anymore. She only felt: the thick cock opening her, her aunt’s finger on her clit, the heat rising and rising until something inside her broke. Her first real orgasm hit like a slow but unstoppable wave. She clenched hard around Ylva, inner muscles gripping the cock with force, and let out a long, shaky moan that fractured in her throat.
Ylva couldn’t hold back any longer. She pushed in to the hilt one last time and stayed there, buried completely. Her balls tightened and she started to come in thick, hot spurts, flooding Summer’s virgin pussy until it overflowed. She felt every pulse, every heavy rope of cum leaving her and staying deep inside her niece. The cock throbbed hard, emptying itself completely, and a little white semen began to leak out around the shaft, trickling down Summer’s thighs.
Summer felt the sudden heat, the flooding inside her. She frowned again, that adorable, confused expression Ylva already knew, but she didn’t move. She let her aunt finish, let every spurt fill her more. It was strange, sticky, but it was Ylva’s. And she liked it. She liked it so much that, without thinking, she squeezed her inner muscles as if trying to keep it all in.
Ylva stayed still, holding Summer against her chest, the cock still inside, twitching with the last remnants. Her hand stroked the girl’s back in slow circles while both their breathing gradually calmed.
Summer hid her face in her aunt’s neck, still trembling from the orgasm. She felt the warm cum inside her, slowly dripping, and a very small, new part of her mind wondered what would happen if that… if that did something more. But she didn’t ask. She just stayed there, breathing against Ylva’s skin, feeling full, used, and in some strange way, protected.
Ylva kissed her hair softly, eyes closed. She said nothing about what had just happened. She didn’t speak of consequences or what it meant. She simply held her, letting the silence stretch between them, heavy with everything neither of them was ready to name yet.
Ylva’s cock remained half-hard inside Summer, as if it didn’t want to leave. And Summer, with shaky legs and a body marked by her aunt’s hands, made no attempt to move.
