John never knew a silence so defining as the few moments when he sat with his back to the door, and Grace waited patiently outside for an answer. He didn’t know how to answer was the problem. That wasn’t the kind of question he would have expected; then again, he was expecting her to make more of a statement, such as, “I’m calling Mom and Dad/The cops!” Nor was he expecting her so sound so subdued. Most surprises- good or bad- usually set her off like a firework; a little shriek as she zips around before eventually exploding. Such a difference in mood made him more wary and unwilling to make a move.
Grace tried once more. “John… it’s okay, I’m not mad or anything. Just kinda, well, surprised I guess.”
Yeah, I’ll bet! He thought to himself. Though he wasn’t exactly relieved, he noticed that her voice wasn’t wavering like it usually would when she tried to hold back her anger or fear. She seriously didn’t seem as bothered by what happened as he had thought. He finally took a deep breath, clearing his head a little. While he still didn’t want to face her, the fact that she was making a peaceful move to confront him about it rather than the aggressive tactics she was known for made it a little easier to get back on his feet and prepare to face the music. 
With a shaky hand he slowly unlocked his door, making the knob rattle as he turned it. There she was, standing with a friendly smile on her face and her hands behind her back, though her eyes failed to look him in the face. He couldn’t blame her, with how awkward the whole situation was. The most he could do was stare in her general direction, either past her to the opposite wall or above her at the hall lights. 
Neither one said much at first, aside from ‘um’ and ‘so…’ as they both fidgeted in place for a few seconds.
Unsurprisingly to either party, Grace was the first to speak up. “Sooo… that was a bit awkward, huh?”
John finally looked her dead in the face, albeit incredulously. Awkward as Fuck would have been closer, but even he felt like that didn’t even remotely cover the entire situation. He had literally been jerking off behind his sister’s back and had just jizzed on her leg. It went beyond awkward and straight into creepy as hell. Yet here she was, smiling- almost in embarrassment it seemed- at his doorway like he had just simply let slip a curse word in front of her. 
“I’m not entirely sure you understand what just happened here!” He surprised himself by even forming a complete sentence. But the surprise of her happy-go-lucky reaction to his actions was greatly outweighing his fear of being arrested at the moment. 
“Maybe not, but…”
“… but you’re not mad? Not even a little shaken up?”
“Nope!” It was a very matter-of-fact response, with absolutely no hesitation. “I mean, I thought I was scared at first, but I’m actually kind of, well, excited.”
“You’re kidding me!” He didn’t mean to say it out loud, but it was already written all over his face anyway. Any other girl, no matter what age, would have likely beaten the snot out of him while calling the cops. 
“Nope!” She responded with a small smile.
After a few seconds of stunned silence a sudden thought came to him. Ridiculous as it was to think that she wasn’t freaked out at all, this was the same girl who craved attention in many forms. She never cared whose eye she caught or how many heads turned from what she said; she just wanted to be looked at, admired, even despised if she couldn’t get anything else. Perhaps being sexually admired by her older brother was flattering to her; fucked up and ludicrous as it seemed.
John just shook his head, rubbing his temples and sighing in exasperation. “Christ, this can’t be real!” Again, he didn’t mean to say that out loud, but it didn’t seem to matter what slipped out anymore.
Grace wasn’t done blindsiding him apparently. “So was that your ejactolate that got on my leg?”
John froze for a second trying to process what she just asked. “What!?”
“Ejactolate, like the stuff that comes out of your penis when you orgasm?”
“I think you mean ejaculate… and yes, that’s technically what happened.” That at least proved she had been given some sort of ‘sex talk’ before. It was a valiant effort for trying to sound smart, but of course she proved once again that she only half listened.
“It’s really gooey!” Was all she said at first. John noticed that her fingers on her right hand had something smeared on them, and he had a small burst of unwanted excitement to think that she had been playing with his jizz. “Is it always like that?”
“It… is for me at least.” He shook his head again, trying to steer things in a new direction. “Nevermind that though! It’s super gross and you should really start to wash it off before your fur gets all matted!” 
Grace looked at her leg for a moment and the streak of semen that was already starting to dry on it. “I guess I should, huh?” She giggled sweetly, and it was driving John even crazier. “Could we talk more about this after though?”
“We’ll see, maybe. Just get too it already!”
“Okay!” she skipped over to her room to grab her shower robe, while John grabbed a spare towel and underwear from his room and headed downstairs to his parents bathroom. More than just wanting to keep his junk from being too musky he just wanted to find some way of calming down a little more. 
As soon as he was stripped down and under the shower head he turned the knob to blast him with icy water. The shock to his system did the trick, and even under the frigid water he felt himself finally calm down. 
He adjusted it to a more bearable temperature before cleaning himself off, trying to keep his head clear of any thoughts as he washed his junk. Then he just stood there for a short while, trying to think through the situation a little more clearly. Sure, it was great that she wasn’t mad, but the fact that she seemed to enjoy such attention didn’t bode well for future possibilities. He had to talk to her again, more seriously this time. This was a big enough mess as is and he didn’t need a bigger one popping up on down the line.
He suddenly heard the shower curtain rustle and felt a chill go over him. He whipped around to find Grace standing just outside the shower in nothing but her robe, and he reflexively tried to cover himself. 
“How the hell did you get in here!?”
Grace smiled with a small giggle. “You didn’t lock the door silly!”
God dammit he thought to himself. “Never mind that, why are you in here anyway!?”
She started undoing the sash of her robe, “I just thought it would be more fun if we showered together.” Just before she started to pull her robe off John turned back around and shut his eyes tight. His dick betrayed him, trying to fight against the hands that covered it.
“Grace, get out of here!” 
Even though he should have just forced her out or tried to be sterner, the fact was that he was finding it harder and harder to deny that this was something he wanted. The internal struggle wasn’t even a close battle now that Grace was making a move on him as well. 
He heard her step into the shower, and then give a slight yip of surprise. “Jeez it’s cold! You don’t always take showers like this do you?” 
John didn’t say anything, he just started breathing more heavily as he cracked an eye open to see her arm reach past him to the shower knob. Moments later warm water cascaded on both of them, and he started to notice how much it felt like his blood was starting to boil.
“There, much better!” Exclaimed Grace as she placed her hands on John’s shoulders, making him jump slightly. She giggled again, “Calm down John! It’s not like there’s anything wrong with this!”
She can’t be serious he thought to himself. “There’s plenty wrong with this and you know it!”
She didn’t say anything, likely disregarding his comment, as she reached for their Mom’s shampoo bottle. “You wouldn’t mind moving would you? I want to get more under the stream.” She didn’t really wait for a response as she nudged herself past him, and he felt her nipples brush against him. His cock twitched in his hands and he quickly moved to the back of the shower and faced the opposite direction again. 
He could have just jumped out of the shower then, just quickly grabbed his towel and bolted to his room again. But his true interests and feelings for the situation kept him firmly planted, even if he was still too scared to act on his impulses. 
“Can you help get my back John? Please?” He heard her ask rather sweetly. 
He finally dared a glance over his shoulder and his cock twitched more aggressively this time. Even if it was just a back view, the sight of her nude body was just too much for him. Somehow her butt seemed curvier than it did when she wore those tight shorts of hers. Her tail wagged slightly, splashing water on the shower wall and the curtain. He looked away again, his face flushed even deeper and hotter than ever. “I’d… rather not.” He finally said.
“Aw, why not?”
He sighed heavily. “I, well… I don’t really trust myself. There’s no telling what’ll happen.”
“What are you talking about?” she asked with slight cluelessness in her voice. “I don’t care if you touch me John. C’mon, just help me wash my back. Pretty please?”
That sweet voice that she tried on everyone normally never worked, but in this instance it was rather disarming and compelling. John eventually turned to her, dick at full mast and aching with every pulse; grateful that she was too preoccupied with suds in her hair to even catch a glimpse over her shoulder.
He grabbed the soap she had set aside for him, lathered it into his hands, then nervously started to reach out to her. His cock twitched with his frantic heartbeat once his fingers made contact with her back, and he almost forgot to keep breathing when his palms started to rest against it. It was a ridiculous amount of effort to continue, considering the semi-innocence of the action, but he eventually did start to work in the lather, which made Grace hum pleasantly. 
“Thanks John! It’s so nice to finally have someone help me with that. I may be kinda flexible, but washing my own back is still annoying.”
“Uh-huh,” was all he said. He barely even registered anything she had said. While there was a conscious effort to help her wash her back, instinct slowly started to take over the lower he got. He started panting a little when her rubbed along the small of her back, the urge to reach lower and grab that curvy teenage ass growing more and more. Before he knew it it was already happening, and Grace just gave an innocent giggle. “You don’t have to wash there John, I can get that myself.” She said as she bent over to wash her leg finally. 
Damn you and your cluelessness he thought to himself, staring at her ass more as he got a clear view of her pussy. She may have known that he was admiring her body, but she clearly didn’t understand the position she had put herself in. John’s reservations were diminishing rapidly the longer he had his hands on her, and very soon, all bets were off.
Not a second after Grace had rinsed the soap off of her leg, she suddenly found a pair of arms wrap around hard and hug her close to her eager brother; something hard and fleshy pressed between her butt cheeks.
It was Grace’s turn to gasp as she tried to look around at him. “John! What-“
“I told you didn’t I?” he whispered in her ear. “There’s no telling what could happen.”
His right hand started tweaking her left nipple, eliciting a small, surprised squeal he had never heard her utter before. It drove him crazy to hear her already making such lewd sounds, and his left hand lowered to her inner thigh while he started to kiss her neck. 
She squirmed in his arms, at first seeming like she wanted to fight him off, but eventually the movements felt less deliberate and more sporadic. He couldn’t believe how she was handling this, and it just made him want her even more.
He rubbed his cock between her ass cheeks as he continued to fondle her, his left hand starting to trace along the outer lips of her pussy. He felt her shiver at his touch. 
“John! This feels so weird!” she said a little nervously, though obviously warming up to it. 
He teased her pussy lips more before spreading them slightly, and Grace started letting out small howls of pleasure. Her sounds started making him a little over zealous, and his kissing and fondling intensified to the point where he started slipping a finger into her, and she let out a slight yelp. It was enough to make him snap out of it for a second to realize what he had almost done. 
Grace may have been one to flirt, but she did so innocently. She had never fooled around with anyone, and likely never even touched herself; and the evidence of her virginity was more than apparent to him now.
He pulled his finger out, hugging her a little more gently this time. “Sorry Grace, I was getting a little ahead of myself.” He nuzzled her gently. “I’ll stop if you want me to, but if not then I need to make sure we take this a little slower.” He hesitated for a moment, and when she didn’t answer he started to let go of her. But before he could draw his hands away, she gently laid her own on them.
“No, it’s okay John.” She turned to him, a small smile on her face that was more genuinely sweet than he had ever seen her give before. “I actually liked it.” She lightly placed his hand back to her groin, then looked down at his cock. She tentatively reached out, grasping the shaft lightly in her soft hand. John couldn’t help but give a soft moan from that. 
They looked at each other again, John smiling a little awkwardly. 
“Can we keep going?” asked Grace, as if they were playing a simple little game.
John nodded, feeling no reservations or qualms about his situation anymore. “Sure Grace… but maybe not in here.” He reached around to shut of the water. “I’d hate to try and explain to Dad why the water bill was so high over the weekend.” She giggled a little at his dumb joke.
“Seriously though,” he continued as he hugged her again. “You’re going to be going through a lot of firsts tonight, and I want to make sure we do this the right way and in the right place. Okay?”
“Okay!” she replied as she hugged him back. Even with their wet bodies starting to feel a bit of a chill from the air, there was an inner warmth that they shared in that moment; an affectionate kind that neither one had truly shared as siblings before. John felt happier than he had in a long while, and he had Grace to thank for that. He was going to make sure that this would turn out to be a pleasant experience for her.
