A/N: I want your honest opinion on this piece here. I am so not used in writing lemons, so...a few hints here and there would be nice.
"Hey Jo?" the sister spoke to her brother, using his nickname.
"Yeah Caro?" Joseph used his sister's nickname in return.
The young man got up from his crouching position and turned towards the shower curtain, where he could see the shadowy silhouette of his sister.
"Can you...help me with something?"
He could see her moving, turning her back to him.
"Er…'kay? Need some shampoo or something?"
"No, not that. There's something...on my back."
"On your back?" Joseph crossed his arms and tilted his head in confusion.
"Yeah. It feels like something is burning there a little. Can you take a quick look?"
"Er...uh...what?" The brother asked, taken aback by the request. "Your back?"
"Yep. I can't exactly turn my head around that far."
"Er...okay. Just turn off the shower for a sec. Don't wanna get the place flooded."
Caroline grinned to herself, as she turned around and stopped the flow of water onto her naked skin. The effect on her was almost immediate, as without the warm water her wet skin started to cool off. The young woman wrapped her arms around her chest area, in order to somewhat compensate for the lack of heat.
Behind herself, Caroline could hear the shower curtains being shoved aside. Joseph took in a hissed breath, before speaking. "Okay...where exactly am I supposed to look? And why are you wearing a necklace in the shower?"
"In opposite order, because I felt like it and it's right here." Caroline swung her right arm around and rubbed with her hand on a spot on her back, which was located barely above the location of her ass cheeks.
Blushing a little bit, because now he couldn't just keep his sister's hips out of his field of vision, Joseph took a closer look at the spot his sister was rubbing on.
"Hmm...I don't see anything...well, it is a bit red. Does it itch?" Joseph carefully went with his finger over the spot.
"No." His sister replied. "Just burns a little." Inwardly she was glad for the little coincidence. Her brother may be lazy, but far from dumb.
"Hmm, my guess would be you have a little rash. I don't exactly have any kind of cream here for something like this, only against burns." He explained, rubbing his chin. "I guess I'll add that on the things to buy for tomorrow. But else, you're feeling fine, right?"
"Yeah, everything's fine. By the way" Caroline turned around, causing her brother's eyes to widen for a split second, before he quickly turned his entire body around, making splashing noises with her feet.
"Whoa, whoa there sis! A little bit of forewarning would be nice."
His sister giggled at his words. "I told you already, I don't mind if you look. We've seen each other naked since we were kids. It's not like I'm showing you anything, you haven't seen before."
"You're doing this on purpose, aren't you?" he grumbled, his face completely red. "Is this revenge for eating the last slice of cake or something?"
"Oh, come on. Stop being silly." Caroline replied in a childish manner. "Unless you really are attracted to me, then I feel flattered, but you're not really my type."
"Uuurgh…" Joseph groaned, facepalming. "Is this some kind of side effect from drawing too much hentai? Or are you on drugs?"
"I'm just fine."
"I highly doubt that."
Caroline giggled again. Unbeknownst to her brother, she had stepped out of the shower, her steps were muffled by the towel she placed on the ground earlier.
"Didn't you want to tell me something?" Joseph asked, still oblivious to his sister standing behind him. "If not, then-"
Before he could finish the sentence, he could feel Caroline pressing her naked body against his back. Joseph himself hissed in surprise, taking in a deep breath, while the female sibling wrapped her arms around him, pulling him even closer to herself. He could feel her warm breath on his, causing shivers to run down his spine.
Now there were a lot of things going through Joseph's head at this very moment. Some were possible explanations for his sister's behavior, others sexual fantasies he didn't even know he could imagine. Still, despite all of those...distractions, he still managed to calm himself considerably down, at least from an outsider's perspective and managed to say his next sentence with his deadpan voice.
"You soaked my clothes."
The brother tried to think of anything that might distract him from this particular situation, though the increasing blush on his face didn't help.
"Mhmm, guess you need a change of clothes," Caroline whispered into his ear.
"...Seriously." he breathed out. "What did I do to you that you'd start screwing with me in that way?" Inwardly he wondered if it would be an overreaction to lash out at his sister. He considered it to be a "maybe", since apparently, she had decided to move around him, keeping her body firmly pressed against his own, until she was right in front of him, her wet hands going through his messy hair. She gave him that one smile, the one she always gave him when she had done something to intentionally get him mad. Yup, she was screwing with him. He was convinced now.
"Why do you think I'm screwing with you?" She spoke to him in her erotic voice. Joseph "replied" by given her a deadpan stare.
"Maybe I am just trying to be a nice sister?" she whispered coming ever closer to her brother's lips. Said brother could feel his face heating up more than on a hot summer day. His lips quivered, while another shiver went down his spine. Still, he managed to keep his face straight, expecting Caroline to pull back all of the sudden and start laughing out loud. That never happened.
As soon as their lips met, Joseph's brain short circuited. His eyes widened, his breathing almost stopped, his back straightened out, all the while his sister gave him a kiss directly on his own lips. His first kiss ever given by another girl. The kiss only lasted for a couple of seconds, but Caroline followed it up by another soft kiss. Then another. And another.
Caroline's hands slowly trailed down her brother's back, until they reached his waist. Not ending the slow stream of kisses, the sister slowly pulled up the shirt her brother was wearing. Like in a daze he raised his arms and allowed her to take off the shirt. Gently she rubbed with one hand over his chest, while the other one gently pulled his head closer, until their lips met once again. Caroline's nipples gently rubbed themselves against her brother's man-nipples, tickling both brother and sister.
After an especially deep and lengthy kiss, Caroline slowly walked around her brother, her hand trailing along Joseph's body. When she let go of him, she gave him a coy smile and a wink, before re-entering the shower. The brother could only stare after her, as she slowly closed the curtain behind herself and turned the shower back on. With her face hidden, Caroline smiled triumphantly to herself, when she heard her brother dropped his trousers to the ground and probably got rid of his underwear soon after. Her smile grew wider, when she heard the shower curtains being moved to the side and her brother stepping into the shower, his bare feet creating splashing noises on the ground. She had her back turned to him at the time, standing directly under the shower head and waited for him to make the first move.
Joseph for his part hesitated just long enough for Caroline to believe that she needed to make a move. However, he eventually found the courage to do something, namely putting his hands on Caroline's ass cheeks and slowly rubbing over them, as if he was savoring the feeling. His sister encouraged him to do more by putting her hands on his and pressing them firmly against her cheeks. This resulted in a certain part of her brother's body to touch her right leg very lightly.
"You like this, don't you?" she asked him, not expecting an answer. She turned herself around, giving her brother a good look of her breasts once again. His face turned a deep shade of red once again, but he didn't look away. She looked down her brother's body and for the first time in years got a good look at his cock. It wasn't exactly what she expected and she meant that in a positive manner. His cock was not the longest she had ever had inside herself, but it was still above average, not to mention thick. She was positively delighted to her discovery. Grinning, she took the hands of her brother once again and placed them on her breasts over her hard nipples. Her brother, who had been looking at her new necklace just a second prior, now had his eyes drawn to her breasts once again. His heart raced a mile a minute at this point, with his cock standing at attention and pre-cum already coming out of it.
Joseph slowly massaged his sister's breasts, causing her to let out a small moan. Caroline stepped closer to her brother, making sure his hands remained on her assets and gave him a deep kiss. This time she included her tongue, invading his mouth and wrestled his own tongue into submission. The male sibling moaned uncontrollably, feeling his cock twitching in anticipation. Caroline wrapped her arms around her brother and pulled him closer, pressing their bodies together. She could feel his cock rubbing against her stomach.
Before any of them ran out of breath, Caroline broke the kiss and looked at her brother with bedroom eyes. He for his part appeared to be in a mixture of shock and excitement. After giving him a small kiss on the nose, she bent on her knees and took her brother's cock into her hands. Joseph's entire body jerked at the touch and along came continuous moans. The volume of those moans increased when Caroline skipped the handjob and took the cock straight into her mouth. Breathing through her nose, Caroline moved her head back and forward, causing the cock to twitch inside her mouth. Her brother lacking in experience and self-control, couldn't hold it any longer.
"Caro...Caro...I….I….AHHH!" Just as the scream pierced her eardrums, the salty taste of thick, sticky cum assaulted Caroline's tastebuds. Her brother's cock throbbed inside her mouth, as it continued to spray the white goods into her throat, which she was more than eager to swallow. Her tongue slowly licked around the cock, making sure to not miss a single drop of cum. Joseph at this point panted heavily, his face red and his eyes closed. Never had he felt this kind of pleasure before. A small part of him told him that this was wrong, but it was drowned out by the sheer amount of pheromones clouding his brain.
Once her brother stopped cumming, Caroline released his cock with a sloppy plop sound and straightened herself. With still some cum left in her mouth, the sister kissed her brother and put the sticky, salty substance right into his mouth. Still dazed, the young man accepted the treat without any resistance. One has to question whether he was even aware of just what he was swallowing.
Caroline, however, wasn't done just yet with her brother. There was one final treatment she had for him and for herself for that matter. Using her superior strength, she gently brought her brother down, being careful not to slip up on the wet ground. Once both were sitting on the ground, Caroline gently pushed Joseph on his back. She then proceeded to take his cock in both hands, first rubbing it slowly and over time picking up the speed, until the male sexual organ became hard again. All the while Joseph could do nothing more, but moan in pleasure and press his arms against the walls of the bathtub the siblings were in.
Once Caroline found she had sufficiently prepared her brother, she positioned her own sex organ above Joseph's cock and wrapped her pussy around the thing. The moan that escaped her brother's mouth was so loud, she expected him to orgasm here and there, yet he somehow managed to hold himself back for the moment.
"Get ready brother," Caroline said before she started to move. Both siblings moaned and groaned, as the feeling of pure ecstasy went through their bodies. For Joseph, it was his very first time and for Caroline, it was a completely new experience, since she was technically doing something illegal. There was just something exciting about the notion of having sex with your own family member. In fact, she became so excited that she couldn't help herself, but to grip her brother's chest, digging her nails into his skin. Joseph let out a scream in pain, though it could have easily been mistaken for a scream of ecstasy.
Blood began to run down Joseph's body, something only Caroline noticed, due to Joseph having his eyes closed. The sister leaned over and began licking up all of the blood, not slowing down one bit in her motions. This was the breaking point for the male sibling. Letting out a primal scream, he couldn't hold it back anymore. Caroline could feel the warm cum filling her womb. She was pleasantly surprised when she noticed that her brother came just as much, if not even more than previously and managed to fill her up. After one final moan, Joseph's entire body became limp from complete exhaustion.
Caroline could see that her brother had hit his limit already, which was unsurprising given his lack of experience. She herself would have enjoyed if this continued on for a little while longer, but there was always tomorrow. Leaning forward, Caroline gave her brother one final kiss, before resting her body on top of his, the shower keeping them warm for the entire night.
