Author's Note: This is an immoral story, it's bad, it's corrupting, you shouldn't read it. Incest, masturbation, oral sex, fountains of male ejaculate onto nubile female bodies -- you have been warned!
And as always all characters are adults!
Angela stood next to her younger sister's bed smiling as she watched the sleeping form below her. Yesterday was Chloe's eighteenth birthday but today was going to be even more special. Chloe was laying on her side, her back to Angela. Her golden hair flowed over the pillow her head was snugged into, her breathing deep and peaceful.
The older girl sat on the edge of the bed next to the still sleeping form, brushed the blonde hair away from her sister's face. "Time to get up sleepyhead" she said gently. She felt her sister shift, move her head even deeper into her pillow. Angela grinned and leaned to bring her lips against her Chloe's ear. "Rise and shine, today's your special day, that present I promised you? Remember?"
That brought a smile to her not quite awake sister's lips, and her eyes slowly opened. "Hmmmm" Chloe replied, waking up. "I do remember Angie." She rolled onto her back and grinned up towards her older sister as she stretched. "You're going to explain how you went from being flat chested like me to" and she nodded towards her sister's chest.
Angela's eyes twinkled as she chuckled. Truth be told it was probably genetics that caused her breasts to balloon forth -- and she hadn't started out quite as small as Chloe was suggesting. But the rapid growth she'd experienced over the last year or so did happen to coincide with... well...
"You have to promise not to say anything to anyone. I mean really
really
promise Chloe." Her face took on a serious cast and her eyes locked onto her sisters.
"Uhm... is it something dangerous?" Chloe wondered and her face took on a concerned look. "Was it some sort of experiment?" Her eyes got wide at the thought of her older sister taking some sort of hormone or worse steroids!
Angela chuckled again and brought her hands to her chest and cupped her breasts. "Uh uh -- all natural and totally organic" she stated and burst into a giggle as her sister goggled, her eyes glued to her boobs.
Giving herself a second to stop the giggles Angela finally said "No silly, it wasn't dangerous -- well, not in the way you're thinking. But if you said something to -- anyone, anyone at all -- people you love would get into some serious trouble."
The urge to laugh disappeared after saying all that. "You have to swear that you'll keep this to yourself -- or if you don't think you can we'll just leave things alone. And something else to think about."
Angela grinned lopsidedly as she watched her sister think about what was being said. Then continued. "Just because this worked for me doesn't mean it will for you. But..." Her grin turned more intense. "You'll probably have a blast anyways."
She gave her boobs a final squeeze as her sister watched wide eyed. She knew Chloe was jealous about her rack and who knows? Maybe what she and daddy had been doing for the last year may have had something to do with how big they grew after all.
"I promise" said Chloe, then brought her fingers to her own chest. "Cross my heart" and did so grinning. "Scouts honor too!" She moved and sat up in the bed. "So come on Angie and tell me!"
Angela took a breath. "Okay. A couple of days after I turned eighteen..." Chloe's eyes got wider as Angela told the story. She'd found their dad jerking off -- he thought he'd had the house to himself and wasn't as careful as he'd probably always been. She got wildly turned on watching, it was late in the evening and it was clear her dad had drunk a little too much. That probably had a bit to do with what happened next, as he'd only meekly protested as Angela walked up to him and proceeded to take over.
"You gave daddy a hand job?!?" Chloe was almost bug-eyed as she said it. Then giggled.
Their parents had divorced years ago and their mom had at first got custody. It had been an article of faith between the two girls that the only time their parents had sex at all was when they were conceived. But their living with her became impossible and so both girls were able to convince everyone as they got into their teens that they should live with their dad.
Angela giggled back. Then pumped her right fist up and down. It took a few minutes for the two to catch their breath. "Ye... yea... Yes. I did." Chloe looked at her older sister conspiratorially.
"What was it like?" she demanded breathlessly, intently interested.
"You -- if you want to -- are going to find out yourself" Angela responded grinning broadly. "We've been doing it ever since -- and I got the idea of not wasting it so..." and pointed to her boobs with both of her index fingers.
