The eye contact seemed to spur her brother on and embolden him. His hands erupted into a concerto of groping along her hips as he humped her slit, and then slipped up inside her t-shirt and cupped her breasts before focusing on her nipples with his fingertips. His hands were large and his fingers long and they took command over her body in a way that was both overpowering and seductively sensual.
Katy’s mind was reeling. Even though this very taboo scene is what she secretly wanted, the intensity and wrongness of it played on her mind even now in the midst. Nonetheless, if her mind was conflicted, her body responded in a powerfully affirmative way. She felt herself coat his cock with her juices as he continued to hump himself along her from behind. Every touch on her skin set off an explosion of sexual energy that shot across her nerves like bolts of electricity.
While her brother’s hands explored her body, he nuzzled into her shoulder and began kissing and nibbling at the skin of her neck up to her ear. When he reached her ear she heard him whisper breathlessly and desperately.
“This is so fucked up, but I need my fucked up, slutty little sister right now! Fuck I need you!”
His voice was different. She had known it to always be so soft and loving, though low-pitched. The way he was speaking to her was dark, urgent, and commanding. It reverberated in her ears and reached down into her consciousness and set loose something very primal and very wrong. It made her tremble in his hands and on his throbbing cock. Katy let out a single, long, desperate gasp into the night air of the cabin.
Her brother’s moans were becoming more urgent. He broke his contact and flipped the top of the sleeping bag away from them violently and scrambled to take up position behind her. Katy positively drooled arousal when he rose to his knees and roughly pushed her into a position laying flat on her front. She was still unable to speak, but thought in her mind, So this is how he is when he’s horny!
Katy yipped in surprise when his strong hands gripped the sides of her hips like a vise and pulled her up to her hands and knees. She bit her lower lip and shot a look over her shoulder while he clumsily and desperately yanked her thong over her ass so it hung between her thighs. The room echoed with the fleshy slap of him smacking her round backside with the length of his cock. Her view wasn’t entirely ideal but she saw it throbbing, his head flared and a vein encircling him. He was curved leftward and upward and she felt herself pulse at seeing him for the first time. The cock slapping ceased then she felt him diving down between her legs until his tip found the source of her sopping wetness. This was it… the dirty and taboo thing she had been fighting within herself all day. She was about to take her brother’s cock…
Katy balled her hands into fists when she felt the pressure of his first thrust begin to sink inside her. She moaned into the floor while he stretched her and plunged into her hungry opening. Whether it was due to the wrongness of the situation, Jeff’s size, or some combination of the two, the sensations were more intense than she was prepared for. Katy found it nearly impossible to keep quiet and let out a series of moans when he landed his full length inside of her for the first time. It was then that she felt his hand reach around her face and cover her mouth. The lingering notes of her own taste were on his fingers that were now clamped over her lips. He held his hand there as he pulled back his hips before pushing back into her ferociously. The act of her being muzzled in such fashion turned her on in a way she hadn’t expected. She wasn’t just fucking her brother, she was being taken by him and made the object of his pleasure in that moment.
Katy had always been curious about how her brother acted in his intimate moments. Though before present, it was much more innocent curiosity. He had always been so caring and thoughtful with her and most of the people in his life. It excited Katy to see that there was indeed a hungry animal lurking in her brother’s personality, and now that animal was being released on her curvy body.
Jeff continued to pound away at her from behind, attempting to stifle his own verbal outbursts and swearing under his breath. The harder and faster he thrusted made Katy involuntarily lower her shoulders so her face was practically on the floor. Her brother was one of the more generously endowed partners she had to that point and his full length and girth slamming into her rocked her body with sensations that were part pain and part pleasure. Eventually her legs gave out as well and she was again prone on the floor with her brother’s long body over her back. Jeff planted his elbows just above her shoulders to keep her close to him as he continued to rail her from behind.
From that position, Katy could feel the curve of his manhood rubbing along her g-spot with each motion. Her body began to clench and tremble beneath her big brother. She whimpered desperately into Jeff’s hand until he suddenly slammed them down flat on the floor. She sucked in a deep breath of air before she let out a desperate plea.
“Nnnngggg…. Jeff!” her voice reduced to a breathless rasp.
Her body went into the seizures of climax. Her walls clamped on her brother tightly as if begging him to meet her at the zenith of orgasm.
Her brother echoed her sentiment, his mouth directly behind her ear. In a low, guttural groan he let out, “Fuck, Katy… FUCK!”
With that she felt him burrow deep inside her and begin to throb and pulse. His hips kept pressed tightly against her ass while she felt the torrent of cum begin to fill her. They both laid there, sweat beading off their skin against the cold night air in the cabin, both gasping almost in unison. He gave her several more thrusts and their voices harmonised their dirty song into the air. Katy’s lips trembled, her breathing nearly stopped and her body milked every last drop from her brother for what seemed like an eternity until he collapsed over her back.
He lay on top of her for several breathless moments. She could feel his ribs moving as he searched for breath above her. Then he rolled off and slipped out of her, clumsily laying beside her like a boxer who had just been knocked down. She suddenly felt so empty without him inside her. She could feel she was swollen, dripping, and satisfied. After she managed to catch her own breath, Katy turned her head to face his direction and caught his eyes again. The look in them… the sparkle of happiness, the relief of a desire fulfilled… she grinned sheepishly and blushed.
Katy didn’t want to be the first one to speak at risk of disrupting the incestuous magic that was unfolding between them. She also was having trouble forming words due to her body still being a case of convulsing nerves. The drips of her brother’s cum that were beginning to seep out between her lips nearly made her giggle.
Jeff was the first to break the silence. “Fuck I needed that!” he said in an excited whisper. He then rolled onto his side and put his arm around his sister. “I think we’re officially fucked up now, Shortcake.”
Katy was caught ill-prepared for her brother to be cuddling her. It was quite unlike any of the grief-relief sessions she had with the boys at university. She had grown accustomed to quick encounters with no meaningful contact after the fact. She felt her eyes tearing up and hoped their glassy appearance was lost in the dim light from the fire.
She rolled to her side facing her brother and laid her hand on his chest before replying. “We both needed it… and I don’t mind being fucked up with you… not nearly as much as I should anyway!”
The two locked eyes again, and try as she might, she couldn’t keep the single tear that threatened to plummet from the corner of her eye in place. Her brother’s arm was around her, the same arm that she had come to know as a safe place of comfort and now a place where she could have her desires fulfilled. She could feel his still rapid heartbeat against her hand on his chest. She was deep in the throes of a full-on crush on her big brother who had just taken her like she was the only thing that he wanted in the world.
