The morning sun poured gently across Ayaka's home, cicadas humming faintly outside. Kana arrived, her sandals crunching on the pebbled path as she carried a small paper bag of Kyoto sweets for her friend.
She knocked softly on the door.
"...Ayaka?"
No answer.
Frowning, Kana knocked again, then tried calling out. The silence made her brow crease. She walked around the side of the house, her fingers brushing against the old wooden wall, until she reached the window near Ayaka's room.
That's when she froze.
Her lips parted in shock, a flush rising hot across her cheeks.
Inside—through the thin curtains—she saw Haruto kneeling on the futon between Ayaka's legs, his face buried deep in her pussy. His hands clutched at her thighs, spreading her open wide as his tongue worked furiously. Ayaka's hips writhed, her fingers tangled in his hair, her face tilted back with bliss.
"Ahhh—H-Haruto… yes… right there… lick my pussy more!"
Her voice was raw, dripping with satisfaction. Ayaka's tits bounced slightly as her chest heaved with pleasure, Haruto's hand squeezing and kneading one breast, thumb flicking over her hardened nipple.
Kana's heart hammered in her chest. She stumbled back a step, her breath caught in her throat—but her eyes refused to look away.
Every wet, slurping sound of Haruto's tongue echoed through the paper walls. Every moan Ayaka let slip made Kana's thighs clench together tighter.
Heat pooled low in her belly.
Her panties grew damp almost instantly.
Kana bit her lip, gripping the wooden frame of the window with trembling hands. Her breath came fast, ragged. The sight of Ayaka's face—eyes rolling back, mouth open in helpless cries—made Kana's body throb with a strange, desperate need.
"…Gods… why does this feel so hot…?" she whispered to herself, cheeks burning.
Her free hand slid down almost without thought, pressing against her skirt, her fingers feeling the wet heat soaking through the fabric.
Haruto moaned into Ayaka's cunt, his tongue flicking mercilessly as her body twisted with ecstasy. Ayaka's cries grew louder, her face glowing with sweat, her body trembling on the edge.
Kana's knees went weak.
Her heart raced.
And then—unable to fight it anymore—she slipped her hand under her skirt.
Her fingers brushed against her drenched panties.
Her pussy lips throbbed against the damp cloth.
Her breathing hitched.
And for the first time, Kana gave in.
Kana's breath hitched the moment her eyes locked onto the sinful scene through Ayaka's window. Haruto's lips were buried between Ayaka's thighs, his tongue moving in slow, wet strokes as Ayaka's back arched in delight. One of his hands was firmly cupping her breast, thumb brushing over her hardened nipple, while the other held her thigh open.
Kana's heart raced, heat spreading down her body until it pooled between her legs. Her hand instinctively slipped down to her skirt, fingers brushing over her dampening panties.
"Ahh… Haruto… Ayaka…" she whispered, biting her lip as her eyes widened at Ayaka's moaning face.
She couldn't take it anymore. Kana slid her panties aside, exposing her swollen, glistening pussy lips to the cool morning air. Her fingers trembled as they parted herself, one finger circling over her clit, sending an electric jolt through her.
"Mnnhh~… it's so wet already," she whimpered softly, peeking again through the window. Haruto's tongue had just flicked Ayaka's clit, making her shiver in bliss, and Kana nearly lost it right there.
Her middle finger pressed in, slipping past her entrance with a slick, lewd sound. She gasped quietly, biting into her sleeve to muffle it. Her pussy tightened around her finger, sucking it in as if desperate for more.
Her hips started rocking against her hand, grinding into her fingers as she circled her clit with her thumb. The wet, squelching noises of her own arousal filled her ears along with Ayaka's moans from inside.
"Ahhh… Haruto… lick me too…!" Kana panted in a whisper, her eyes hazy, her face flushed bright red.
Her pace grew frantic—two fingers thrusting in and out, thumb rubbing her clit faster, juices dripping down her thighs. She was shameless now, thighs trembling, body pressed against the wall outside the window as she gave herself away to the lust.
Finally, her body snapped. Her pussy tightened violently around her fingers, and she slapped her other hand over her mouth to stifle the scream threatening to burst out. Her orgasm rolled through her in waves, juices spilling over her fingers, dripping onto the ground below.
She slid down the wall, panting hard, her hand still buried in her soaked pussy as the aftershocks left her trembling. Her eyes lingered on Haruto inside, still pleasuring Ayaka.
"Girls… really do… masturbate…" she whispered to herself with a weak, breathless laugh, lifting her glistening fingers and staring at the shine of her own lust.
Kana leaned weakly against the wall beneath Ayaka's window, her body still trembling from the orgasm that had left her legs quivering and her fingers soaked. Her chest rose and fell with ragged breaths, each inhale tasting of sweat, lust, and forbidden pleasure.
Her thighs glistened with streaks of her juices, dripping onto the grass below in sticky trails. Slowly, shakily, she pulled her fingers free from her pussy, and the wet sound of them slipping out made her blush even deeper. Her hand gleamed with her own nectar, strands of it stretching between her fingers.
She stared at it for a moment, dazed, before bringing her hand closer to her face. The smell of her own arousal filled her nose, making her shudder again. She spread her dripping fingers apart, watching the glistening threads of slick connect and break.
Her lips parted in a breathless, delirious laugh. "Haahh… look at me… I couldn't stop myself…"
The muffled sound of Ayaka moaning Haruto's name still echoed faintly through the window. Kana's eyes fluttered shut as she whispered out loud, shameless and drunk on lust:
"Girls do… masturbate…"
Her gaze dropped between her thighs, to the mess she had made of herself—her pussy swollen and red, slick with her climax. She rubbed her thumb gently over her clit again, shivering at the sensitivity, before sliding her soaked fingers across her entrance one last time, smearing her juices over her folds.
With a shaky smile, cheeks flushed and breath uneven, she whispered again, firmer, almost proudly this time:
"Girls… do masturbate."
And with that, she pulled her panties back up over her dripping slit, the fabric immediately clinging to her wetness. She gave one last glance inside the window at Haruto and Ayaka, her eyes dark with desire.
Next time… it'll be me, she thought, her heart pounding.
Then she slipped away from the window into the morning air, leaving behind only the faint scent of her lust lingering on her fingers.
