Karla woke up smiling as her alarm rang its 6am alarm. 19 and full of life, her dark brown hair flowed across her pillow, her pale skin almost as white as her sheets.
Karla felt the nipples of her 32D sized breasts harden as she had a very special thought. Her older brother Ben was in the next room to her sleeping still. The rest of her family was all still asleep and would be until around 7-7.30ish. Plenty of time for her to enact her plan.
She arose from her bed, her breasts falling gloriously across her chest as she did. She quietly picked up the red bra and panties from her bedside table and got dressed with her first deadly layer of weapons. She then picked up her little black nightie next to them and got dressed with her second layer of weapons.
Ready for the fight she planned on winning, she tip toed out of her room slowly closing her bedroom door. She tip toed to the next room and quietly opened the door.
Lying there fast asleep was Ben. 20 years old and a big lad. Built like a truck wall to wall muscle, but Karla knew exactly how to bring down men like him.
Karla tip toed over to his bed. Thinking about Ben's big, veiny cock inside her filling her with exactly what she needed and knowing she would carry that inside her in front of her family without them ever knowing. These thoughts got her a nice wet patch in her panties and she rubbed herself under her nightie.
Sliding her fingers underneath her panties to her she slid her finger between her pussy lips covering her fingers with her lovely wetness. The scent of which would drive any man over the edge of sanity.
Taking her finger out of her panties she bit her lip and climbed onto the bed straddling Ben. Ben stirred and slowly opened his eyes looking up at his younger sister. Her pale legs either side of his waist, her plump ass sitting on his boxers. Her breasts ready to burst out their bra and nightie neckline as she looked down at him with a look a woman only gets when they desperately need male seed.
"W-wha-" Ben began confused.
Karla's wet hand dashed towards and clamped around his mouth before he could make another sound. Karla smiled as she watched Ben breath faster in surprise breathing in her wet scent from her hand centimeters away from his nose.
"Shhhhhhhhh." Karla put a finger against her lips.
Ben became more and more docile as her wet scent took effect on his body and the monster in his pants began to stir under Karla's supple ass. Ben's eyes glided over the black nightie, it's neckline plunging revealing pale breast flesh. The sides of the nightie tightened towards her accommodating her curves, showing off her shapely hips. Ben's monster stirred with heat as he fell for Karla's first layer of weapons. Ben felt tingles of anticipation run through his body, his sexy little sister was sitting ontop of him all wet and wanton.
"Mmmmmmm." Karla quietly moaned, as she began to grind her firm young ass cheeks against her older brother's tented boxers. Karla pulled down the neckline of her nightie with her other hand exposing her second layer of weapons. A red bra and heaving breasts threatening to burst it. Her breasts bounced as she began to grind her brother faster. Ben was transfixed by his little sister's supple bosom, round pale breast flesh bouncing above him, the hairs on the back of his neck standing up. The hint of a brown areola appeared as one bounce sent Karla's left breast almost out of the cup of her bra.
Ben breathed heavy loving each bounce and his hands rose and grabbed the dress of Karla's nightie. Pulling it up Karla raised her hands and let her older brother undress her. The sight of her big pale breasts smooshed together in her straining red bra sent Ben's tent hard up against Karla's ass cheek.
"Awwwwe don't cum yet big brother..." Karla whispered.
"W-We can't be doing this." Ben whispered back.
"Oh really?" Karla whispered back, turning to face away from him and bending over showing him her plump apple in her lace panties.
"Oh god." Ben moaned, cupping one of his sister's supple ass cheeks in his hand. The thrill of having such sexual tension between them surging through his spine.
Karla raised her legs and sat her ankles on her brother's shoulders. Then crawled with her hands backwards til her chest sat just above his tent. Looking back at her brother and the 69 position she was now in, she grabbed the lining of his boxers and pulled them down, his monster erection sprung free.
"Ohhhh no no." Ben protested.
Karla clamped her thick pale thighs around her brothers neck, locking her ankles together.
"Shhhhhhh big bro. You'll wake everyone up." She whispered with a wicked smile.
"N-n-no." Ben struggled to say as his sister's thighs choked him.
"Awwwe was that a no big bro?" Karla whispered, taking her bra off, casting it aside she settle her firm, big breasts around his meat pole. "Gottcha!" Karla thought.
"How about now?" Karla whispered, looking back at her brother as she began rubbing her breasts up and down around his cock. Ben's eyes rolled back and she felt his breathing quicken against her ass.
Karla loosened her grip with her thighs, risking Ben crying out, but pressed her ass against his face to muffle any cries. Ben didn't make a move or say a word. Unsurprising, she thought, who wouldn't want to be smothered by his sister's lovely ass. Karla wiggled her ass against Ben's face and Ben's meat started to pulse.
"Mmmmm that's right bro, no one refuses your little sister, not even daddy or mommy." She whispered looking back at him with a smirk.
Ben groaned into her ass flesh as his balls started to tighten with each stroke from his sister's breast flesh.
"Uh oh, I just told you my secret." Karla whispered placing a finger to her lips. "Am I going to have to choke you so hard with my thighs you forget any of this happened?"
Ben moaned into Karla's ass and shook his head.
Karla giggle, "Mmmmmm good boy." She whispered.
Ben started to struggle to breath, suffocating in his sister's amazing ass. His hands shot up and grabbed at her ass cheeks and thighs trying to pull them apart.
