The calendar had turned to the middle of July, and the house felt smaller every day. The heat pressed in from outside, thick and unrelenting, turning the rooms into slow ovens. Lila moved through them like a ghost — quiet, watchful, always aware of where Evan was. She caught herself lingering in doorways when he passed, breathing in the faint scent of his soap and summer sweat. She noticed the way his T-shirt stretched across his back when he reached for something high, the way his shorts rode low on his hips after a run. Every detail fed the ache that lived between her legs now, constant and insistent.
She used the new dildo every night. The stretch was better now — deeper, fuller — but it still wasn’t enough. She coated it generously with lube, pushed it in slowly, savoring the way her pussy yielded, the way the thick shaft pressed against every sensitive spot inside her. She fucked herself harder each time, hips lifting off the bed, imagining Evan above her — bare, relentless, groaning as he buried himself to the hilt. She pictured his cock swelling, pulsing, then the hot rush — thick ropes of cum surging deep, coating her walls, filling her until it spilled out around him, dripping down her thighs.
She came hard, walls clamping down on the silicone, thighs trembling, but the moment she pulled it free the emptiness returned — sharper, hungrier. She lay there afterward, slick and panting, listening to the sounds from down the hall: the rhythmic thump of the bedframe, Rebecca’s rising moans, Evan’s low growls. “Yes ... deeper ... fuck me ... fill me...” She timed her next orgasm to them, fingers on her clit, imagining it was Evan’s cum flooding her instead of her mother’s.
The messages kept coming. She saw Evan’s face change every time the phone buzzed — small, private smile, fingers flexing, shoulders settling. She watched him read them in the kitchen, on the couch, in the hallway, the outline of his cock thickening visibly in his shorts more often now. Rebecca was relentless, sending texts that made him shift in his seat, hand brushing casually over the growing bulge before he typed back.
Lila knew what they said now, even if she couldn’t read them. She could feel it in the air between her parents — the tension, the heat, the unspoken promise of what happened after dark.
By the middle of the third week, she couldn’t stand it anymore.
Sunday night, July 17, the house was quiet. Tyler asleep. Evan in the shower. Lila stood outside Rebecca’s office door, heart hammering against her ribs. She knocked softly.
Rebecca looked up from her desk, the warm lamplight catching the curve of her cheek. She set her book aside immediately.
“What’s wrong, baby?”
Lila stepped inside, closed the door behind her. Her voice was small, hesitant.
“I ... I can’t stop thinking about it.”
Rebecca’s gaze sharpened, but she stayed seated, waiting.
“About what you told me,” Lila continued, words tumbling out now. “About him ... being inside you. Without anything. About ... finishing inside. Filling you.”
She swallowed, cheeks burning.
“I’ve never had that. Never felt someone ... come inside me. And thinking about it ... I get wet. Every day. Every night. I can’t make it stop.”
Rebecca leaned back slightly, eyes dark with recognition.
“Tell me more,” she said softly.
Lila’s breath hitched. She wrapped her arms around herself.
