Kelly winced and exhaled a relieved breath as the 10th and final blow fell and she lifted her naked body off her father's lap. She stood, sniffling, and looked at her father, his gaze gradually softening from the one he'd been wearing for the last thirty minutes. She reflexively covered her exposed boobs and sex, but dropped her hands to her sides quickly after a stern, wordless glare from her father. Experience told her this was not a battle she should try to win, and after all- she knew she was guilty.
Standing there in the buff, she briefly lamented the trouble she has caused not only to herself, but to her poor brother as well. Kirk stood against the wall, equally naked, head down and arms at his side, thick penis dangling between muscular legs. Ever since her chance encounter with it a few days ago, Kelly had been obsessively trying to catch another glimpse of that strange organ. It still seemed huge to her, even though it was considerably smaller than when she'd accidentally walked in on her brother. Now that it was clearly on display just a few feet away, she could not bring herself to do more than steal a quick glimpse of it, avoiding her brothers' eyes.
"Against the wall Kelly," instructed her father and she took her place next to her brother; the two contrite teens awaiting the lecture they both knew was coming. Kelly wasn't sure whether it was worse that she still got spanked at her age or that, because of circumstances that were all her doing, she was now being punished together with her mostly innocent brother. Kelly felt absolutely awful. She had begged, pleaded, and cajoled her brother using every trick in the book, playing on the fact that she knew he adored his little sister. She had batted her eyes and played on his affections to engage him in the little conspiracy that was the reason for their current predicament. Kirk was really a great brother. He was always there for her, always looking out for her, and was utterly adored by her girlfriends as much for his good looks as for his friendly demeanor. Some of them had big brothers too, and none got along with them as well as Kelly and Kirk.
Having to undress in front of her male family members was just one of those things Kelly has learned to live with; the two siblings had been punished together for most of their childhood, and were used to seeing each other in such an exposed state. Kelly had always been secretly fascinated by his body and now that she was older, she knew that there had been just the slightest hint of sexual excitement at their shared nudity. It's not like she was particularly prudish and as her body had filled out, she got a kind of perverse pleasure in making her brother uncomfortable, waking around in a towel or skimpy nighty, showing off her changing body. It was a safe way to explore her budding sexuality with someone she trusted and loved. She thoroughly enjoyed his attention, and was secretly delighted to catch him looking at her when he thought she wasn't paying attention.
Their punishments were not something they talked about with each other; much less something they shared with their friends. Their dad was a strict, old-school disciplinarian and only rarely punished them anyway, which made their current situation all the more traumatic. They had not expected this kind of punishment at eighteen but 'Lying to Father' was at the very top of his list of punishable transgressions and apparently, 'Getting a tattoo on your twat' was the new second place entry; beating out last year's 'Throwing a Rager when dad was out of town.' That punishment had been just as bad, but at least then she still had her thick, dark bush, which she only recently realized offered a considerable amount of visual protection for her privates. That time, Father had also spanked her nude, but Kirk had just been sitting in a chair nearby observing. Even then, she was secretly proud of the effect her naked body had on her brother and she could see him squirming in his seat though she could not remember if she had actually seen his erection through his pants.
Father was lecturing them on choices, responsibility, consequences, and a bunch of other stuff Kelly was perfectly happy to ignore; especially when it came to getting something she really, really wanted. She had been discussing her tattoo with her friends for months and with her brother for weeks; wearing down his arguments and finally breaking him down to where he even agreed to lend her some cash and give her a ride to the parlor where the 'deed' would be done.
Kelly glanced down at the still red rose tattoo just above her freshly denuded sex. She had intended for her brother to ever see it though of course he knew about it and its intended location. She had certainly never considered having her Father see it at all, but even now, she thought it had been worth it. "I'm going to have to make this up to Kirk" she thought to herself. "Really make it up to him."
Kelly briefly met her brothers' eyes before he looked away again. His lingering embarrassment from their earlier encounter was still fresh. Kelly had walked in on him unexpectedly- catching him mid-stroke masturbating to porn in his room. He had been lying on his bed, watching something on his TV and his erect penis had looked huge in his hand; the dark purple head clearly visible above his clenched fist and the long, veined shaft glistening with the lotion he was using for lubrication. "Was that my expensive skin cream?" Kelly had randomly thought. His balls too, seemed absurdly large between his legs, and the shock of the encounter temporarily froze them both. Kelly had stared wordlessly for several seconds, looking not at his face, but directly at his exposed member.
Kirk regained his composure and pulled a pillow over his lap, after which Kelly had mumbled a quick "Sorry!" and ran off to her room.
For days afterwards, the image of her brothers' cock had been burned into her mind; its size, its shape, the glistening wetness, the very "maleness" of it made her nipples hard and her own sex wet in response. She had let a few boys slip their hands under her shirt and had even let one slip a hand into her pants, though his awkward fingers had considerably difficulty navigating her dense foliage to find her treasure. Kelly had spent many hours since in bed rubbing herself, the image of her brothers large, erect cock her only fantasy material.
Perhaps not realizing what she was doing she had been teasing him relentlessly the last few days. In the throes of her mini-obsession, she wanted to see his penis again, wanted that rush of sexual energy, wanted to feel that tingle deep within her pussy. She had walked into his room wearing just a bra and panties to casually ask him a question, but with the real intent of seeing how he reacted to her semi-transparent attire. She knew her dark bush and nipples would be visible through and that there were even a few hairs peeking visibly above the low-cut waistband. To her great delight, he had noticed, and his expression left no doubt that he had been excited by the view. She left before her nipples had hardened and the small, growing damp spot became obvious.
Father's lecture was over, and Kelly snapped back to reality, sneaking another quick glance at Kirks long, limp penis dangling beside her. His thick pubic hair reminding her just how naked her own sex now appeared.
