Jake slammed the door behind him after their parents left for the weekend. At 22 he was done playing big brother from a distance. His 19-year-old sister Emma stood in the kitchen in tiny shorts and a tank top that barely hid her tits. She looked nervous but curious, exactly how he wanted her.
"Get over here," he said. "You asked what fucking feels like. I'm teaching you for real."
Emma bit her lip but walked to him. He grabbed her hand and pressed it against the hard bulge in his jeans. "That's my cock. You're going to learn every inch of it."
He didn't waste time with soft kisses. He shoved her tank top up, yanked her bra down, and sucked hard on one nipple while his hand went straight down her shorts. Two fingers pushed into her pussy without warning. She was already wet.
"Fuck, you're soaked," he growled. "You've been thinking about your brother fucking you, haven't you?"
Emma moaned and nodded. Jake finger-fucked her fast and rough, thumb rubbing her clit until her legs shook. "Say it. Say you want your brother to teach you how to take cock."
"I want you to teach me," she gasped. "I want my brother's cock."
He pulled his fingers out and shoved them in her mouth. "Taste your own cunt. Good girl." Then he pushed her to her knees right there on the kitchen floor. He unzipped, pulled out his thick cock, and slapped it against her cheek. "Open. Lesson one: suck your brother's dick."
Emma wrapped her lips around the head and he immediately thrust deeper, fucking her mouth in short strokes. Spit ran down her chin while he held her hair. "Relax your throat. Take more. That's it, choke on it." He held her head and pushed until her nose touched his stomach, then pulled back just enough for her to breathe before doing it again. When he finally let her up, strings of saliva connected her mouth to his cock.
"Strip," he ordered. She peeled off her clothes fast. He bent her over the kitchen table, spread her ass cheeks, and licked straight from her clit to her asshole. Emma cried out. He ate her pussy hard, tongue fucking her hole, then switched to her ass, getting it wet and sloppy. Two fingers slid into her pussy while his tongue worked her rim.
"You're gonna take my cock in both holes before the weekend's over," he told her. "But first you learn how to come on your brother's dick."
He stood, lined up, and shoved his cock into her pussy in one hard thrust. Emma screamed. He didn't give her time to adjust; he started pounding, hips slapping against her ass, balls hitting her clit with every stroke. The table scraped across the floor from the force. He reached around and rubbed her clit fast and rough.
"Come on my cock, little sister. Come for your brother." She came hard, pussy clenching and squirting a little around his shaft. Jake kept fucking her through it, then pulled out and flipped her onto her back on the table. He pushed her knees to her chest and drove back in, going even deeper.
"Look at me while I fuck you," he said. "This pussy belongs to your brother now." He fucked her fast and dirty, sweat dripping, the wet sound of her cunt taking him filling the room. When he was close he pulled out, straddled her chest, and jerked off onto her tits and face. Thick ropes landed on her skin while he groaned her name.
They didn't stop there. He dragged her to the couch, made her ride him reverse cowgirl so he could watch her ass bounce, then bent her over the arm and took her ass with spit and slow, steady pressure until she was begging him to fuck it harder.
He did, gripping her hips and slamming into her tight hole until he filled her ass with cum.
Later that night he fucked her again in their parents' bed, missionary this time, slow and deep at first so she could feel every inch, then hard and fast until she came twice more. Between rounds he made her suck him clean, taught her how to swallow, and told her exactly how her brother liked his cock worshipped.
By Sunday night Emma was sore, marked with hickeys and handprints, and leaking cum from both holes. Jake pulled her against him on the couch and kissed the top of her head.
"Lesson complete," he said. "Next time I'll teach you how to beg for it."
Emma smiled against his chest. "Yes, brother."
