“Honestly, Sean! I don’t know where your mind goes sometimes!” his wife chided him.

It might have bothered him in the presence of anyone but his sister and her husband. Kylie knew where his ‘mind goes sometimes’ and offered a knowing smile.

They’d both been married a few years now, but despite the pact they’d made that magical night when the spanking they loved escalated into the ultimate act of love, neither had been able to keep their promise once married. They had both ended up with spouses they loved in every sense of the word, and with all their hearts, but neither was getting the spankings that had drawn them together in their early college years.

“Honestly, Sean!” Kylie mimicked Sherry, his wife, “I should give you a spanking!” she said with her lower lip firmly between her teeth.

“Yeah, I wish!” Sean replied to Kylie’s sympathetic face.

“Careful what you wish for!” she said as she looked around to see if they were alone. She had a proposal for the brother she loved more than just a sibling.

“I still remember that pact we made. What happened, Kylie? Were we just two naïve kids making promises we couldn’t keep?”

“I intend to keep my promise!”

“Don’t make it worse! I remember that day like it was yesterday! I hate to admit it, but it was still the most amazing day of my life. Sherry hasn’t got a clue, and I’m sure she’d think I’m a total perv if I came right out and asked her to do it.”

“Same with Brad. We saw a brief spanking in some movie, and I commented on how sexy it seemed, and he just looked at me with that ‘What’s wrong with you?’ face.”

“You know how we said we loved each other? That we were not ‘in love’ with each other? Well, I was lying a little. It felt more like that special kind of love to me.”

“Oh my God, Sean!” she remarked, and he wondered whether he’d said too much. “I can’t believe it! I felt the same way!”

“You did!?”

“Yes, I did,” she replied with emphasis on ‘did.’ “I don’t anymore, Sean, and I don’t think you do either.”

“Yeah, you’re right. I wish you weren’t, but you’re right,” he replied just to agree with her.

“Don’t be sad, Sean. We were just kids then. But that doesn’t mean we can’t have some of that same fun!”

“Don’t tease, Kylie!”

“I’m not teasing, Sean!” she said and looked around again, seeing their spouses talking in the living room. “Let’s go outside,” she suggested. “Listen, Brad’s going out of town next week. Do you remember offering to help with finishing our basement?”

“Yeah, but isn’t Brad doing that?”

“He’s trying, but he’s useless with tools. I’m doing most of the work, and he just looks at me in wonder. His dad was a bit better than he is, but didn’t teach him to use tools like ours did. Why don’t you come over a couple of nights that week to help me?” she said, putting air quotes around ‘help.’ “No one would question a brother and sister working on a project together.”

“Are you sure?” he asked with trepidation.

“I don’t know about you, but my bottom has been aching for a good spanking, and you’re the only one who can give it to me! C’mon, Sean! Please?”

“I’ll have to make sure Sherry doesn’t want to come along!”

“Just tell her it’s going to be dirty and dusty, you know, sawdust! She hates that!”

“Okay, when?”

“Monday and Tuesday, so we each have a night. And we’d still have Wednesday and Thursday if we want more!”

“Oh my God, Kylie! Are we really gonna be able to do this?” he asked, his anticipation blatantly apparent.

“Piece of cake! Oh! Hi, honey!” she said when Brad turned up outside to join them.

“What are you two cooking up?” he said, prompting guilty looks from them both. “I’ve never seen a brother and sister as close as you two!” he added, his comment a result of being an only child and having no idea what it was like to have a sibling.

“Brad, Sean just had a great idea! While you’re away next week, he’s going to come over in the evening and help me with our basement project!”

“That is a good idea! Between the two of you and your talents with tools, you should make a lot of progress!”

Kylie made a face at Sean, saying, ‘Now we’ve got to deliver!’ with her eyes.

Sherry arrived and had to be filled in on the plan, having mixed feelings about being alone for possibly four straight nights.

Kylie was having mixed feelings the following day about their plan. On the one hand, she was highly excited, having been years since she and Sean had to stop their spanking play when she was about to get married. Of course, it wasn’t just spanking, and she lost count of how many times they’d fucked each other, but it was always preceded with one over the other’s knee getting a ‘good’ spanking that they would have likely cum from as well.

They’d gotten so good at it, their climaxes reaching higher and higher as they tried new positions and occasionally a new paddle from Sean’s efforts in their dad’s workshop. They’d even tried new locations; a local park, a hotel room when on vacation with their parents, and even their car, but their best times were always at home, usually in Sean’s basement bedroom. When their parents had left them home to go on a romantic vacation for a week, their unbridled play resulted in multiple spankings each day, all over the house, and severely bruised bottoms.

But things were different now. They’d both married within a year of each other, and though their play continued while they were dating, it had become less frequent as relationships got more serious. She remembered the day she had to tell Sean they had to stop. They’d both ended up in tears, and neither mentioned their ‘pact,’ unable to see how it could work.

With their parents as role models, she swore herself to fidelity when she married, but while sex with Brad was still exciting, it lacked the extra something that an over-the-knee spanking provided. A couple of times, she lay herself across Brad’s knee when they were in bed naked, declaring herself a naughty girl for one reason or another, and Brad had even given her a few playful spanks but never took the hint that she wanted more. The whole experience left her missing Sean’s expert hand as her ‘daddy’ spanking her hiney even more.

All these thoughts in a single day left her confused as to whether she should carry through on their plan. Sleeping on it a second night, though, resolved the conflict, and she decided to do it, but they just wouldn’t follow it up with sex; well, maybe fingers and tongues.

Sean had similar thoughts, though he never considered not doing it with Kylie. While he unequivocally loved Sherry and everything else she’d brought to his life, their sex tended to be somewhat repetitive, occasionally thrilling, but usually just satisfying.

Sherry had caught him once looking at a picture on the internet, but he explained it as an unexpected result from clicking a link, and she accepted the explanation. He almost wished she’d looked more carefully at the image of a man across a woman’s knee with her hand on one cheek while the other glowed red. Maybe it would have prompted a conversation where he could finally admit his desires. While he also missed giving spankings, he’d be more than satisfied if he were only a recipient of such funishment.

His wandering mind often frustrated her, and he wondered what she’d think if she knew how often it was the thought of spanking that his mind wandered to. How appropriate it would be if, instead of scolding him for his lack of attention, she yanked his pants down, tossed him over her knee, and spanked him good and hard.

He, too, would go through with their plan, as now that Kylie had opened the door, he’d be damned if he didn’t step through it.

He arrived at Kylie’s Monday night feeling like his anticipation might cause internal injury. Kylie helped him unload his tools and bring them to the basement, where various building materials were scattered about.

“You can see the result of Brad trying to frame the walls,” Kylie said, not needing to point out the unevenly spaced and even crooked studs. “He said, ‘What does it matter if they’re all going to be covered up anyway,’” she explained, laughing.

“Okay, well, we’ll need to tidy up a bit so we’re not tripping over everything,” Sean suggested, and minutes later, the studs were stacked neatly in the middle of the room, and other paraphernalia placed out of the way, leaving a single dinette style chair in the middle of the space. For anyone else, it would be just a chair used for various innocuous purposes, but they shared a conspiratorial look when it was no longer camouflaged by the mess.

They started by removing the crooked and poorly spaced two-by-threes. Kylie marked off the header and baseplate for sixteen-inch on-center studs while Sean measured the height between them to be sure it was consistent and started cutting more to size. Two capable hands and a pneumatic nail gun had one wall fully studded in less than an hour.

They spoke in clipped phrases and single-word instructions to keep their mind on the work, but they couldn’t deny the energy in the room. Suddenly, Kylie threw herself into Sean’s arms, relishing the familiar comfort they offered.

“I can’t stand it anymore! Please?! I need to be spanked, Sean!” she begged and smiled when he took her hand and led her to the chair.

Standing before him, she knew the evidence of her arousal must be obvious. He stared at her ultra-tight shorts with a pronounced slit, a dark line emphasizing its depth. They hadn’t discussed whether they’d do anything besides the spanking, but they’d both wondered how they could avoid it. Sean looked straight at her cameltoe, with the dampness spreading, then up at her with a question in his eyes. She nodded slightly.

“Ohhh!” she cooed as his finger slid through the damp crevice.

“You’ve been a naughty girl, haven’t you, Kylie?”

“I’m sorry, Daddy! Are you gonna spank my hiney?”

“Yes, I am, and it’s been a long time coming, I must say!” he said as he pulled her shorts down.

The lack of panties was neither surprising nor unexpected, but Sean refrained from touching her again, knowing what she really wanted first. Taking her hand, he guided her to his side and down across his lap.

“Oh my God, Kylie! You have the most beautiful bottom in the world, but it really needs a good spanking, doesn’t it?”

“Yes, daddy! Please don’t spank my hiney too hard!” she said with a touch of concern that after so long, they’d need to take it easy at first. “Oh!!” she yipped at the always startling first spank.

She couldn’t believe it was finally happening. She’d begun to think she’d never do this again, but the stinging slaps and sound of his hand smacking her cheeks were heavenly. During the long abstention, she’d tried to figure out why she wanted and needed this, but now, on Sean’s lap, finally getting her spanking, she didn’t care why. She just absorbed the smacks from Sean’s expert hands, which hadn’t lost any of the magic touch he’d developed long ago.

They hadn’t discussed who would go first, but Sean’s ever-present respect for his beautiful sister made the choice obvious in his mind, and while he wanted the same, he was quite happy to have her perfect cheeks willingly submitting to his hand again. Their spherical shape, deep cleft, and soft, smooth skin (at least before he spanked her) provided plenty of pleasure for him. Writhing on his lap and moaning as the spanking went on and on brought back such fantastic memories of discovery they shared.

“Had enough, Kylie? For now, anyway?” he asked as he massaged dark pink cheeks.

“Oh, God, Sean! It feels so good! Make me cum while you spank me? Please?” she pleaded as she tried to open her legs for him, but her tight shorts held them close together. “Oh yeah!” she said when he dragged them down her legs, and she kicked them off.

The spanking resumed with his left hand from above as his right slid up the inside of her thigh, a loud gasp accompanying first contact with her swollen, sensitive lips. Gentle touches became persistent rubbing of her delicate folds until two fingers found their way inside with louder exclamations and pleas for harder spanks.

“Holy shit! Hoh! Hoh! Oh, my G … oh my G … ohhhmmm!” she gasped as the climax was finally reached.

She collapsed across his lap in exhaustion, with a shiver passing through her body every few seconds, savoring Sean’s delicate touch, soothing her enflamed cheeks.

“Oh, Sean! I have missed that SO much!” she cried as the thought of doing without it again saddened her.

Sitting up in his lap, she put her arms around his chest and rested her head on his shoulder. Sean stroked her back with one hand and her bare thighs with the other, his intent only to soothe.

Sliding off his lap between his legs, she reached for the waist of his work shorts and had them open quickly. Her hand touched his hardness and smiled when the head peeked out above his underwear. With a sly smile, she grabbed the waist of both pants and underwear and tugged them down below his knees, her hands going back to his full-size cock to stroke it a few times before leaning forward to take him in her mouth.

“Oh yeah, Kylie!” he sighed as her tongue reminded him of many such times in their past. He recalled the first time when just the thought of his sister sucking his cock made up for any lack of experience, but she’d gotten really good at it over time, and she hadn’t lost her touch now.

When she slipped a hand underneath to tease his bottom, he was close, and the tip of her finger pressed inside was the trigger that had him shooting a mouthful of his seed into her waiting and smiling mouth.

She got up to sit in his lap again, this time kissing him passionately, their eyes speaking volumes about how incredible that had just been. They kissed like lovers, their apprehension about incest long gone, and both knew this wouldn’t be the last time.

“Maybe we should get back to work?” Sean asked. “We’ve got to show some real progress if we’re to keep our underlying purpose here under wraps.”

A minute later, they were fully clothed and back at work, though they knew without saying that Sean wasn’t finished with Kylie’s cute little butt.

They framed the wall and door that would separate this room from the rest of the basement and started on the last one. They had enough framed to work on stringing the wire for lights and outlets.

They talked as they worked together, but there was a constant undercurrent of desire for what they’d do just before he left. Kylie looked at Sean with both affection and lust, anticipating another spell across his knee. Sean watched his sister work, enjoying an occasional peek at her tasty tits down the neck of her loose T-shirt, but as always, it was her bottom he loved more than anything, regardless of her love of a good spanking.

They were tidying up quickly, knowing what would come next, when Sean saw her bent over the remaining studs on the floor. Grabbing her around the waist, he yanked her shorts down and began the final spanking they both knew was coming. Kylie loved the surprise, wriggling in his tight grasp as he spanked his naughty girl’s hiney.

“Oh, Sean!” she cried as he dragged her body to his toolbox, where he fished around to find their favorite paddle he’d hidden there. “Oh yeah! Spank me! Spank me!” she repeated over and over again when she saw the paddle. Back to the chair where she bent over with her hands on the seat, the spanking resumed in earnest with the soft side of the paddle.

“Flip it over!” she cried, wanting to feel that incredible sting of the hard side and his fingers in her pussy as he’d always done. Rubbing and fucking her with his fingers, the paddling escalated quickly, and soon she was shaking with the effects of another unbelievable orgasm.

“Sean! I know we didn’t talk about this, but I really want you to fuck me!”

“But, Kylie, we’d be cheating on Sherry and Brad!” he protested unconvincingly.

“I know, but can you honestly say you don’t want to? Please, Sean! I want to feel you in me again!”

His resistance weakened by all they’d already done, he dropped his pants and guided the tip of his achingly hard cock into her tight sheath, both of them moaning with the memory of days past when they did this at least once a week.

“Oh fuck, Sean! It feels so good to have you inside me again! Fuck me! Fuck me hard, Sean!”

She didn’t have to ask twice as he stepped up the pace and the force, holding her hips and pulling her onto his shaft as they collided with a loud ‘slap’ in the middle. Her body stiffened as she took his much larger-than-Brad’s cock into her tight, young pussy, and she came less than a minute later.

“Oh! Ungh! Hoh! Huh! Huh!” she grunted as Sean continued the onslaught until she could feel the pulses of his ejaculation within the griping confines of her quivering pussy.

He bent over to hug her trembling body until he’d softened enough to fall out of her dripping pussy. She stood and turned to face him with tears in her eyes.

“Oh, Kylie! I’ve missed you so much!” he said, knowing her tears were for the same reason. She wrapped her arms around him, and...
