The heat in the old house clung to every surface like a second skin, thick and sweet with the scent of cut grass drifting through open windows. I had come home for the summer after college, thinking it would be just another stretch of lazy days. Mom was still beautiful in that effortless way, her body softened by years but still curved and inviting in the thin cotton dresses she wore around the house. Dad had been gone for years, and it was just the two of us most nights until my older sister, Lena, arrived from the city with her own restless energy.
It started with small things. Moms hand lingering on my shoulder when she passed behind my chair at dinner. Lenas bare thigh brushing mine on the couch during late movies, neither of us moving away. The air grew heavier each evening, charged with something none of us named until the night the power went out.
We lit candles in the living room, the flickering light turning skin into warm gold. Mom poured wine, her robe slipping open at the neck to reveal the soft swell of her breasts. Lena sat close, her fingers tracing idle patterns on my arm as we talked about nothing. Then Moms voice dropped low.
Ive seen the way you look at us, she said, eyes dark. Both of you. Were all adults here. No one has to leave this house pretending anymore.

Lenas hand slid higher, bold and sure, cupping the growing hardness in my shorts. Weve been waiting for you to notice, she whispered, leaning in to kiss the corner of my mouth.
Mom rose and let the robe fall. Her body was lush, full breasts tipped with dark nipples, hips wide and inviting. She crossed the room and pulled me to my feet, pressing against me so I felt the heat of her through my clothes. Lena stood too, shedding her tank top, her smaller, firmer breasts brushing my back as her hands worked my shirt off.
Clothes came away in a slow tangle. Moms mouth found mine first, soft and tasting of wine, her tongue sliding deep while her hand wrapped around my cock, stroking with long, deliberate pulls. Lena knelt, her breath hot against my thigh before her lips closed around the head, sucking with wet, eager sounds that made my knees weak.
We moved to the wide couch. Mom lay back, legs parted, and guided me between them. I slid into her slick heat in one long thrust, her walls gripping tight as she moaned my name. Lena straddled Moms face, lowering herself so Moms tongue could lap at her. The sight of them together, mother tasting daughter while I fucked Moms cunt, burned itself into my mind.
We shifted and turned, bodies slick with sweat. Lena on her hands and knees, me driving into her from behind while Mom lay beneath her, licking where we joined. Then Mom on top, riding me slow and deep, her breasts swaying as Lena kissed her neck and reached down to rub her clit. Orgasms rolled through us in waves, one feeding the next, until we collapsed in a panting, sticky heap.
Later, in the dark, we didnt pretend it was a one-time thing. Morning found us again, lazy and hungry, exploring every combination the day allowed. The house stayed filled with the sounds of skin on skin, whispered encouragements, and the wet rhythm of bodies giving in.
By summers end the pretense was gone for good. We had become exactly what we wanted: a family that fucked openly, lovingly, without shame. The heat never really left.
