Primal Urges (Closed for Aussie_Wolf)

It was very weird what her brother was doing with that piece of fish, but she was finding it pretty erotic... then again she was a weird girl. She dressed up as a cat and stuck a tail up her ass, and just recently started having sex with her older brother.

But was that all it was? She thought as she felt his lips caress her skin as he traveled up her body and they were looking into each others eyes. She smiled and laughed a little when he said it was the best piece of fish that he had. Sam reached her arms up and pulled him down against her body and kissed him.

No, it wasn't just sex. The weekend's events were certainly not what she was expecting but the experience made them closer than before. She never told anyone about her kinks before and she didn't think anyone would really accept her for them. Sam held David tight as she thought about how lucky she was that he caught her nude on the couch, otherwise she still would have been stuck with just herself. She did have reservations about the initial change but after that big step... everything just felt so natural.

"I'm going to need another bath now." she mused and then thought of something. "Or maybe YOU should clean the dishes... I would be the dish..."
 
David smiled as his sister pulled him into a hug and he returned it. He was amazed at how quickly his life had changed. In one weekend he had gone from being a workaholic guy with no prospects of having a girlfriend and a serious hangup about his sister, to having the girl of his dreams in his life, having the most mind blowing sex of his life and being the most content he had been in years.

He did chuckle a bit as Sam suggested seeing as how she had been the dish he had to wash her. Well that was true he guessed and it was only fair.

"Hmm it is going to be tough getting you in the sink though," he teased her as he kissed the tip of her nose.

"Of course there are other ways to wash you. I could do it in the shower, or the bath of course," he told her. Then getting a glint in his eye he grinned cheekily. "Of course we could stick to your favorite theme and I could wash you just like a cat and lick you clean. Would you like that my little kitten?"
 
"Mmmmm, both a bath and tongue bath sound nice." Sam bit her bottom lip. She knew there were a few places that would need extra attention with that tongue of his.

"And I would like to see you TRY to give me a bath in the sink." She laughed, trying to imagine it her in the sink. The only thing that would be in it for sure would be her bottom... it wouldn't be impossible.

"Most cat's don't like water... you might have your hands full trying to get me clean."
 
David smiled as he took her hand and began to lead her upstairs.

"Well then It is going to be a delightful handful because I have decided to first try to get you clean in the shower, and then I am going to have to give you a tongue bath."

Then he looked at her and chuckled. "On second thoughts maybe we should do that the other way or we could end up needing three baths."
 
"I'm not complaining," She smiled when he suggested switching up his plan. She let her brother lead the way. They by passed their rooms and went straight to the large bathroom they shared. Sam suggested that while the tub filled he could bath her with his tongue.

There was a plush bath mat on the floor and Sam laid her back down and she waited. She was looking forward to him thoroughly cleaning her in certain areas. She was getting excited at the thought of it. She was already of things he could do with that tongue.
 
He looked down at his sister and smiled. She was probably thinking of the things he was going to do to her with his tongue, but he was sure he was going to surprise her. He was going to take his time and give her a thorough going over.

He had deliberately filled the tub with more hot water than cold, making the room steamy and warm. This was to keep them warm, but also to put a thin sheen of water on his sisters body and give him something to lick off and also keep his mouth moist. It was also because he was sure this would take awhile and by the time he was finished he didn't want the bath to be cold.

Smiling down at her he started at the toes of her left foot and slowly licked around them, even suckling on them, before moving up her foot to her ankle then slowly up her leg, past her knee to her hips. He moved close to her pussy then slowly pursed his lips and blew a jet of air across her lips, before licking slowly down her other leg, repeating what he had down just in reverse.

By this time the bath was full and he reached up and turned it off before smiling down at her and again leaning down, this time starting just above her mound and working up her belly and hips. He stopped and teased her belly button before moving on until he reached her breasts, circling them and teasing her nipples, working the gap between them as well before he moved on.

He licked up her sides and under her arms. Along her neck, her ears, her arms, her fingers and then teasingly he turned her over and licked all over her back and down the backs of her legs. Again he avoided her middle section, licking around her ass, but he worked his way back to it and then began to lick all over her cheeks. Reaching up he grabbed the cloth and spreading her cheeks wide he cleaned between them then lowered his face and licked her dainty crack. He avoided her little hole and then he flicked his tongue over it and delighted in her reaction.

Again and again he swiped his tongue over it before he made it into a probe and teased her entrance. However now wasn't the time for any more than this. He licked down further and then eased her over and spread her legs wide until his final target was bared before him. Looking up into her eyes he gave her a warm smile then lowered his head and licked up and down her swollen lips. Slowly he pushed his tongue inside her, deeper and deeper until it could go no further and then he licked back and forth, slowly at first then faster and faster.

Gradually he used his fingers to open her up more, then he moved all over her pussy, licking her lips, her depths and then her clit. He went slowly, he went fast and he went super fast. He went lightly, he went normally and he put hard pressure on her. Finally when he had thought she had enough and the mat looked like it was soaked, he sat back and looked at her.

"I do believe it is time for you to have a water bath now dear sister. However I know how cats hate water so I will get in first and then you will so I can hold you and make sure you don't try to run away."

Smiling he stood up and gingerly got in the tub. It was rather hot and it took him a little bit to sink down in it. Then he held his hands out to her and gestured for her to get in. "Careful it's hot but I think you are going to like it," He chuckled not realizing the double meaning he was giving as his erection almost poked out of the water at her.
 
Sam was in heaven as her brother gave her first bath with his tongue. When he first licked and sucked on her feet, it was a little strange and tickled her at first, but once she was over the initial shock she was surprised by how much she liked it. He continued to lick at her body and she was surprised how certain places made her shiver; kisses and licks on her hip, ribs, the side of her breast (ok that one not as surprising), feeling him sucking on her fingers and ears where turning her on as well. Then she turned over and there was more of her to explore. The back of her knee, when she felt his tongue graze over it her toes curled. She was mewing softly and she could feel her desire burning inside of her.

Then when his tongue slipped over her crack she gasped softly. "What are you- Ah!" She squealed a little as her face flushed bright red. She moaned softly and tried to remain still but he was making it hard to. Then she felt him pushing his tongue against her, briefly which made her moan more and her body pushed back. She was disappointed when he stopped and had her turn over onto her back once more.

She smiled back at him before he lowered his head and she once again felt his tongue tasting her. Sam cooed and moaned with every touch and lick he gave her. He was driving her mad with every change of pace and pressure he used. Just when she thought she couldn't take anymore he stopped and she whined. She was panting and writhing on the bath mat, trying to catch her breath.

Playfully she pouted, "But I was enjoying my tongue bath." and she watched him go into the tub before she joined him.

Sam didn't take nearly as long as her brother did in getting into the tub. Sam always like hot baths and showers and the temperature was perfect. She gave a relaxed sigh as she leaned her back against her brother's chest. One of her favorite things about their house was the huge tub. Grabbing his hands she forced his arms to wrap around her as they sat in the warm tub. She closed her eyes and took in a deep breath.
 
David smiled. He wrapped his arms tightly around his sister and began to nibble on her ear as she leaned back against him. "We are not going to be able to do this for much longer," he whispered. "Mum and Dad are due back tomorrow and then we are not really going to have the privacy anymore except on rare occasions." His stiff erection began to slide up and down her ass as he moved a little trying to get comfortable.

"I was thinking that it might be time for me to maybe get a place of my own. I am doing well at work and I could afford a small place. Nothing too fancy, just a small apartment, but it would be mine."

He then loosened his arms a little and placed his hands on her breasts and began to massage them in slow deliberate circles, his fingers finding her nipples and tweaking them slowly. He rubbed them between his fingers, occasionally pulling them upwards then resuming his slow teasing of them.

"If I did that, would you come and visit me little sis, maybe stay over some nights just to keep me company? he asked.

Samantha moaned softly as her brother played with her breasts. She shifted and moved until her brother's cock was between her legs. She listened to him explain how their parents would be home soon and they would have to be more careful. Still, sneaking around could be fun. Her hand slipped down until she gently pressed her length against her slit. As she rocked her hips, her sex rubbed his which made her moan more.

"Yes, big brother" she purred as they continued touching each other. "I'd try to come and see you every night I can. I can't leave master alone for too long." Gently she rubbed her fingers up and down the underside of his shaft. "I need to make sure big brothers bed is warm. Just like I did last night."

Her body was still on fire from the tongue bath he gave her. They probably wouldn't be able to do that again for a while. Or take a regular bath. Maybe she could sneak into the shower with him. That would be risky but that would also be fun. Then when he moved out they could do so much more. Sam shuddered as she tried to imagine everything they would do. She couldn't wait until it was safe for him to cum inside her. Ever since he took her over the kitchen table she kept imagining him fucking her, breeding her and filling her to the point that she overflowed with his cum.
 
He moaned as she rubbed the bottom of his cock and pressed it up and into her sex. Gently he began to rock his hips, sawing it through her lips as she pressed it upwards. He could actually feel it rubbing against her engorged clitoris and he smiled as he kept the pace nice and slow.

He continued to rub and tease her breasts and nipples, teasing and pinching them as he had come to find she liked. Leaning in he kissed and nibbled on her neck then moved up to her ear.

"I would like that Little Sis. Your Master would be pleased to have his little kitten in his bed to keep him warm while he slept. Of course before they slept he would make sure his kitten was full of his cream. He would fill all three of her holes so full of it she would leak it for days. Would my kitten like that?" he whispered.
 
"Yes!" Sam moaned. His words fueled the images in her head of her brother taking her and using her however he liked. She shuddered at the thought of really being fucked to the point that he dumped all of his cum inside of her, making her a full gooey mess. Her pussy was craving the taste of his cum. Part of her really wanted him to just bend her over the side of the tub and fill her now. She hated that she had to wait for it!

The more he teased, the more she responded. She started bucking her hips more. Every time the tip of his cock brushed her clit it sent shocks of pleasure through her. "Is that your plan for me? Also soon ask master can give me his raw milk you plan on having me dripping with it 24/7?" She purred as her hips rocked, causing the water to move and slush around the tub.

That prompted another thought. Getting up early to get masters milk before she started classes... imagining her panties getting soaked, trying to desperately keep his cum inside. She probably wouldn't be able to concentrate on school, just thinking about when she would get more of his cum.

David thought about that. They had to wait a full week until the injection in her arm made her completely safe and then he could finally experience his little sisters pussy in the truest sense. Would he really want to be with her 24/7 though? He tried to imagine his life with her and then he grinned. Of course he would be fine with that. His sister was a gorgeous woman, she wanted and was willing to have sex with him whenever he wanted and besides that he loved her.

"I would have you bathing in it if that was possible my sexy kitten,"he said nibbling on her ear as he pinched her nipples a little harder. "However I will send you to school with your breath reeking of my cum, your ass full of it and your pussy trying to contain it, and then when I pick you up from school I expect it all to still be there as I top you back up, " he told her as he pressed his cock head up to meet her clit every time she rocked her hips. He wanted nothing more than to take her right then and there but he knew he couldn't.

"I want inside of you little sis, I want to fill you with my milk. You have a choice of two holes but you better pick one quick."
 
Sam bit her bottom lip and shuddered. She knew which hole she wanted it in, desperately. "I... I really want master to fuck and fill my pussy. I need master to fully mark me as his, please." She begged, even though she knew that it was probably not a good idea. She just couldn't deny what she wanted. She needed his cum inside her and she would do just about anything to get it.

It was so risky though. It was probably why she was even more turned on, begging for it. Hadn't she warned him not to cum inside of her this morning? Now she was begging him to. It was like a switch went off when she thought he really was fucking her raw. Now she craved it. All she could picture in her head was being filled and told not to lose a drop, and if she did she would be punished. Punished... that sent another shiver down her body. How would he punish her?

Sam was still rocking and bucking her hips. She moved more, feeling his head tease the outside of her entrance. She just needed to angle herself right... the next thrust, she pushed herself on his cock and the head went in. Sam arched her back and moaned as his thickness started to open her up. Before he could stop her, if he tried, she pushed herself down to get more of him inside her. Her pussy was hugging him tightly. Even if he told her no right now, she could at least be satisfied with feeling him buried deep inside of her like this.
 
David waned to stop her. He knew how dangerous this was, and what the consequences could be, but as soon as she got his head inside of her all rational thought fled.

God she was so tight. He had thought being inside of her with a condom was good, but this was beyond words. He was barely inside of her and it felt like she was gripping him with a vice made of flesh.

He had to stop her before this went too far and his hands reached down to her hips. However instead of pushing her off, they gripped her tightly and pulled her down even as he bucked his hips up to sink more of his shaft inside of her.

"Oh god you are so tight. I can't help myself you little minx. If this is what my little kitten wants then this is what she is going to get. Now sit up and take me properly and turn around. I want to see my kittens face as she rides her masters cock. I want you to tell me how it feels to have it inside your tight pussy that is now only mine, and I want to see your face when I fill you up with my cream," he whispered in her ear.

Sam thought for sure David (now look whose switching names :p teehee) was going to push him off of his cock. Instead she felt him grip her hips tightly, pull her down and shove himself up and fully into her. Her body tenses as she moaned, her tongue hanging out as she felt the head of his cock rubbing against her cervix. She was panting from the excitement of having his bare cock inside of her, she almost missed his orders.

She pulls herself up and without lifting from his cock, she managed to turn around, feeling her pussy twist around his shaft until she faced him. Sam took a deep breath. Her body was trembling. She was going to get her masters cum, her big brothers cum!

"It feels so good to have masters raw cock inside me," she breathed softly. She hadn't dared moved up. She felt like as soon as she did she would orgasm from excitement. "I love masters cock so much... it's touching the back of my pussy." She bit her bottom lip and rocked her hips a little, feeling his cock rubbing her cervix. Her walls tightened and so did her thighs on both sides of his waist. She purred out a moan, and then started to lift herself up and down, causing the water to make waves.
 
As soon as she started moving David could see a problem. Actually he could see several but they were all linked. The main priority though was to let some water out of the bath. If they didn't there was going to be a bloody mess very shortly.

Luckily the plug was just below him and he was able to reach down and grab it. Of course he had to angle his hips upwards to do this causing him to thrust even deeper inside his Sister. Considering just how deep he was already he basically mashed himself dead up against her Cervix as she rocked herself upon him.

It was a mixture of pleasure and pain, but he enjoyed it. Fortunately it did not take long for the water to drain out enough to a level that her movements were not going to cause a tidal wave to crash all over the floor.

Grabbing her hips he looked into her eyes and groaning he lifted her up until just his head was inside her tight entrance and then he pulled her back down onto him hard, again slamming into her rear wall with a loud cry.

"Oh god sis you are so tight. I am going to fuck you and fill you and then do it again until you pass out from pleasure."
 
"Ahhhh!" Sam cried out as she felt her brother grasped hips and pull her down into his shaft until the head once again slammed against her cervix. It hurt but in a good way. And then his words only added to her pleasure. Her walls squeezed around his girth as she imagined him doing exactly as he promised. They really shouldn't be doing this but she was craving it. She needed it. Her body was screaming to feel his, completely unobstructed until the two of them reached their climax.

Sam held onto her brother tighter. Her breath panting heavily in his ear as she tried to ride him at a pace that would build up both of their desires. The water was lower now but she could still feel the water move from the force of her movements. She shifted until her face was near his and she kissed him, hard and hungrily against she tasted his lips. Her moans increased as she felt herself starting to shiver from the build up of pleasure.

"Do you... promise?" She spoke between breaths. Her nose brushed against his as she continued to rock her body. She didn't want their parents to come home, ever. She just wanted it to be her and David, forever. She didn't care if they had to runaway to be together, she just needed him.
 
God he was in heaven. She was the tightest, most energetic, loving, kindest girl he had ever known and he wanted to be with her forever. If their parents never came home he would be sad but then he could have her whenever he wanted and they could be together.

As he continued to thrust into her he marveled at the way she thrust back at him, quickly matching his pace and striving to take every bit of him she could. Her hungry kisses and gasps pushed him to new heights and he thrust harder and pulled her down firmer onto his shaft.

"I promise Sis," he gasped out. "We will always be together." He grunted and strained and with a few final thrusts he could feel himself on the verge of cumming.

"Get ready Sis. You wanted it and now you are going to get it."

With that he pulled her down hard and began to cum, but his head was buried so hard against her cervix it hardly came out and he backed off a little before it flooded out. He squirted a half a dozen times, flooding her and filling her tight confines.
 
Sam came as soon as she felt the force of his cum shooting against her cervix. It felt hot and electric and she never felt like she came so hard in her life. Her brother came inside her. No one had ever cum inside her like this. She didn't think she could ever make love with him any other way now.

When Sam came, her legs clamped around his waist tightly, her body shuddered and everything felt so tight and full. Her breasts were pressed against his chest and her fingers dug into his back. She didn't really mean too, she couldn't help it. It just felt so good... and now she truly felt like she was completely his. Both of their sexs were throbbing and that felt good too.

"I... I love you, David." She said softly between deep breaths.
