It was the third week of May when the heat hit hard, and May found herself alone with her older brother in their parents' big empty house. At twenty-one, May had always been the wild one, the one who snuck boys in and came home with hickeys. Her brother Jake was twenty-four, home from college for the summer, all muscle and quiet stares. They had grown up close, too close, sharing secrets and sometimes beds during thunderstorms when they were kids. But now the air between them crackled with something dirtier.
May walked into the kitchen wearing nothing but a thin tank top and panties, her nipples hard from the AC. Jake was at the table, shirtless, eating cereal. His eyes locked on her tits right away. "Fuck, May, put some clothes on," he said, but his voice was thick and he didn't look away.
"Why? You like it," she shot back, turning to grab a glass and bending over so her ass stuck out. She knew what she was doing. For months she had been thinking about his cock, wondering how big it was, how it would feel stretching her pussy. Incest thoughts had taken over her head, making her wet every time she heard him jerk off through the wall.
Jake stood up fast. "You're asking for it, little sister." He grabbed her arm and spun her around, pressing his body against hers. She felt his hard dick through his shorts, thick and throbbing against her belly. May moaned and reached down, squeezing it. "Yeah, I am. I want you to fuck me like you mean it."
He didn't hesitate. Jake yanked her tank top down, freeing her tits, and sucked one nipple hard into his mouth while his hand shoved into her panties. His fingers found her slick cunt and plunged in deep. "Goddamn, you're soaked. Been thinking about your brother's cock, haven't you?"
"Yes," May gasped, grinding on his hand. "Fuck me, Jake. I want it raw."
He pushed her onto the kitchen table, ripped her panties off, and dropped his shorts. His cock sprang out, long and veined, the head already leaking precum. May spread her legs wide and he slammed into her in one thrust, burying every inch in her tight pussy. She cried out at the sudden stretch, her walls clenching around him.
Jake fucked her hard and fast, the table scraping across the floor with each thrust. His balls slapped against her ass. "Take it, you dirty little slut. This is what you wanted, right? Your brother's dick pounding your incest cunt." May wrapped her legs around him and clawed at his back, moaning louder with every stroke. She came quick, her pussy pulsing and gushing around his cock, but he didn't stop.
He flipped her over, bent her over the table, and drove back in from behind. One hand fisted her hair while the other smacked her ass red. "Say it," he growled. "Say you love fucking your brother."
"I love it," May panted. "Love your cock in my pussy. Don't stop."
They moved to the living room couch next, where Jake sat down and pulled her onto his lap. May rode him reverse, bouncing on his thick shaft while he reached around to rub her clit. Sweat slicked their skin. She leaned back against his chest and he bit her shoulder, marking her. "Gonna fill you up," he warned. "Gonna pump my cum deep in my sister's hole."
May slammed down harder, taking him to the root. When he came, he groaned loud and hot jets flooded her pussy, overflowing and dripping down his balls. She kept riding through it, milking every drop until she came again, shaking and whimpering.
They didn't stop there. That whole week in May they fucked everywhere— in the shower with her pressed against the glass, on the floor of their parents' bedroom, even outside by the pool at night. Jake taught her how to suck him deep, gagging on his cock until tears ran down her face, then he'd eat her pussy until she screamed. She begged for it rough, and he gave it to her, spanking her, choking her lightly, calling her his filthy incest whore while he pounded her ass for the first time.
By the end of the month, May knew this was their secret now. Every time their parents were out, Jake would grab her and bend her over the nearest surface, stuffing her full of his cock and cum. She walked around sore and satisfied, already planning the next time she'd drop to her knees and beg for more. The heat outside had nothing on the fire they kept burning inside the house.
