“It was a sweltering afternoon, and the house was a sauna. The air conditioner had conked out the previous night, and the repairman was yet to show up. Sarah, a 26-year-old redhead with a tight body and perky breasts, was lying on her back on the living room couch, clad in a tiny pink bikini. Her nipples were rock hard and visible through the thin material. She was scrolling through her phone, trying to distract herself from the heat.

A knock on the door made her sit up. She adjusted her bikini top, hoping it wasn’t the repairman already. She opened the door to find Jake, her husband’s younger brother, standing there. Jake was a 24-year-old hunk with broad shoulders, a toned chest, and a mischievous grin.

“Hey, sis,” he said, giving her a quick peck on the cheek. “I heard you guys were having some trouble with the AC. I thought I’d come over and take a look.”

Sarah nodded, feeling a little awkward. She had always found Jake attractive, but she knew it was wrong to feel that way about her husband’s brother.

Jake walked into the living room and immediately noticed Sarah’s state of undress. He raised an eyebrow and smirked.

“Looks like you’re already halfway there,” he said, gesturing to her bikini.

Sarah blushed, feeling exposed. She stood up and crossed her arms over her chest.

“I was just trying to cool off,” she said, defensively.

Jake chuckled and walked over to the air conditioner. He opened it up and started tinkering with the wires. Sarah watched him, her eyes wandering over his muscular body. She couldn’t help but feel a spark of desire.

Jake must have noticed her gaze because he turned around and looked at her, his eyes darkening. He walked over to her and stood close, their bodies almost touching.

“You know, sis,” he said, his voice low and husky. “We could always find other ways to cool off.”

Sarah’s heart skipped a beat. She knew she should say no, but she couldn’t help the way her body was responding to Jake’s proximity. She looked up at him, her eyes wide with desire.

Jake took that as a yes and leaned in, capturing her lips in a searing kiss. Sarah responded eagerly, her body melting against his. She could feel his hard cock pressing against her thigh, and she couldn’t help but grind against him.

Jake broke the kiss and looked down at her, his eyes gleaming with desire.

“Let’s take this to the bedroom,” he said, his voice hoarse with desire.

Sarah nodded, her body on fire with need. She took Jake’s hand and led him to her bedroom. She closed the door behind them and turned to face him.

Jake wasted no time. He pulled off his shirt, revealing his toned chest. Sarah couldn’t help but stare. She reached out and ran her fingers over his chest, feeling the hard muscles beneath her fingertips. Jake groaned and pulled her closer, his lips finding hers again.

Sarah could feel herself getting lost in the moment. She tugged at Jake’s shorts, pulling them down. His hard cock sprang free, and Sarah couldn’t help but stare. She had never seen a cock so big before.

Jake must have noticed her reaction because he grinned and took her hand, guiding it to his cock. Sarah wrapped her fingers around it, feeling the velvety skin over the hard muscle. She started stroking it, and Jake groaned, his head falling back.

Sarah couldn’t help but feel empowered. She pushed Jake onto the bed and climbed on top of him. She positioned herself over his cock and slowly lowered herself onto it. Jake groaned as she took him all in, filling her up completely.

Sarah started riding him, her body moving in rhythm with his. She could feel herself getting closer and closer to the edge. Jake reached up and tweaked her nipples, sending a jolt of pleasure through her body.

Sarah couldn’t take it anymore. She felt herself falling over the edge, her orgasm crashing through her like a wave. She collapsed onto Jake, her body trembling.

Jake wasn’t done yet. He flipped Sarah onto her back and started pounding into her, his hips moving in a steady rhythm. Sarah could feel another orgasm building up inside her. She wrapped her legs around Jake’s waist, pulling him deeper into her.

Jake groaned as he felt himself getting closer to the edge. He thrust into Sarah one last time, burying himself deep inside her. Sarah could feel him pulsing inside her, filling her up with his seed.

Jake collapsed onto her, his body spent. Sarah wrapped her arms around him, feeling content and satisfied.

They lay there for a few minutes, catching their breath. Jake finally pulled out of her and got up. He looked down at Sarah, his eyes softening.

“I’m sorry, sis,” he said, his voice low. “I shouldn’t have done that.”

Sarah smiled up at him.
