Hey there! These are going to be a series of one shots. Some AU, some not, some rated G and fluffy, some PWP (like this one). I only ship SesshomaruxAdult!Rin, so there will not be anything pedophile in nature. *Shudders*

Here is the first one!

Rin knew he was close. She gasped as she felt her hair tugged, claws dancing tantalizingly over her stomach. He pulled her up to him, chest to her back as he continued to thrust into her. She bared her neck to him, and he grunted in approval and nipped her mark. She closed her eyes, feeling her body spasming around his thick cock. "Rin." He panted into her ear.

"Yes, oh Sesshomaru!" She whimpered as she came. She heard a grunt and he thrusted in her harshly, jarringly, and she sighed as he came deep in her. He seemed to have felt the same way as he wrapped both arms around her midriff and licked her mark gently.

"Rin, you are mine alone to see like this." He reminded her and bit into the mark.

She hissed and wiggled a little. But he was still buried in her and he had a strong grip on her. He released her mark and licked in long strokes of his tongue. It only made her desire his tongue elsewhere and she blushed knowing he would smell her reawakened arousal. His response was a chuckle. "I brought you back here to the castle to be my mate. You know I have every right to you then."

"Yes, my Sesshomaru." Rin purred out. She claimed her hold on him and felt his teeth nibbling gently on the shell of her ear. He had admitted he only bedded a female twice before her and she was going to be the last. His yoki was in her, extending her life to match his, they were forever tied.

"Ah, you claim a great deal. Are you strong enough to claim me?" He asked teasingly and rocked into her; his member slowly reawakening.

She closed her eyes for a moment and licked her lips. She nodded and heard him huff.

"In your position?" It was a literal question. He had mounted her from behind and took her hard, they both needed it.

"Yes. I am worthy. I was capable as a child to bring you to your knee. Now that I am grown I have brought you to both of your knees, as you can surely tell." She said softly. He pushed her long raven black hair aside and moved his lips back down to her neck and shoulder.

"So, it seems. Yet, another has daringly tried to see what is mine." He grumbled and pulled out of her.

She did not whimper. He did not like her when she whimpered. He once left her body when she whimpered. He came on her stomach, stroking himself, and denying her pleasure. All because she had whimpered. Even after years of being mates, he had moments where he hated weakness. Whimpering was one. Instead she turned to face him and cupped his cheek, softly stroking the stripes on his cheeks. He closed his eyes in contentment and she smiled to herself and reached up and grabbed the tips of his long pointed ears and rubbed them between her fingers. "Rin." He groaned throatily.

"Hm. Did you not see the demoness who wanted to bed you this evening? Lady Izumi of the East detests me. Perhaps I should remind her I have borne your daughters." Rin said with a smile.

Amber eyes slowly opened, his head moving slowly from left to right, torturous grunts passing between his lips. Eyes half-lidded, he pulled her by her hips and tried to push her down onto the futon. She pinched his ears and he groaned.

Instead she let go of his ears and pushed him onto his back and straddled him. He understood her intent and let his claws dig into her left hip. Grateful that only his right hand was clawed. "Rin. That demoness is a simple wanton whore." He smirked up at her.

"I am Lady of the West. Only I may look at you, undressing you with my eyes. And…" She gripped the base of this hard cock and slid down it easily. "I am the only one who can bed you now."

Sesshomaru groaned and thrusted up into her as she rose and fell down on him. "No one may look upon you as I do." He reminded her. The reason why they were in their chambers during the middle of the day when they were supposed to be finishing their negotiations with the other lords.

"Lord Aito is a fool." Rin said and smacked Sesshomaru's shoulder lightly and rode him faster. Anyone else would have lost their arm for touching him so, yet she heard him huff indignantly at her. She rested her palms on his chiseled abs. Muscles twitching under her touch. "Oh!" She gasped out as he raised his knees and she slid her hands to his shoulders and dug blunt nails into his pale skin.

The moved faster against each other and she leaned down and kissed him, not minding the sting of his claws in her skin. He didn't use his poison on her nor would he ever.

"Ah! Sesshomaru!" She gasped and sat up better, leaning away from his lips. He gripped her tightly and moved her faster on him. She tossed her head back and came. "Fuck! Sesshomaru!" She gasped out.

"Mine." He pressed up into her and came. She felt him release insider and shuddered at the sensation, coming again so suddenly at the feeling. When he finished minutes later, Rin let herself collapse on his chest, buried still inside her. She kissed his chest and shoulder while he rubbed her back and willed himself to relax.

"Maybe more demons should look at me. This was quite the spontaneous session." She laughed and smiled.

"Had you not intervened, Lord Aito would be a puddle of poisonous slime on the onsen floor. How dare he enter our private baths to watch you bathe!" Sesshomaru snarled and rolled them onto her back.

"Ah! You're supposed to relax. Oh! Fuck! Fuck, fuck!" Rin bit her knuckles and moaned around them. He was growing hard again.

She was told about this by his mother. Sesshomaru was going to keep bedding her until she was completely submissive. His demonic nature would not let her rest.

She knew she wasn't entirely human anymore, but she was human enough that having come twice, she didn't know if a third was possible. "Sesshomaru…hmm, no more." She said softly but never a whimper.

"You threatened to let more demons look at you. I have to quell that desire." He growled. His red eyes boring into her.

She laughed and shook her head, "I was teasing!" She squeaked out as fangs grazed up and down her neck, lazing about as he kissed her neck.

"Teasing? Such a dangerous thing to do my love. I fear that a punishment is in order." He reared up and gripped her thighs tightly, spreading them and pushing them higher against her chest.

Rin felt her eyes roll to the back of her head as she writhed beneath him. She was unable to push back at his onslaught and tossed her head side to side. She could feel every inch of him as he thrusted in and out of her quickly. He was panting above her, watching her. She arched toward him as he pounded into her special spot over and over. The spot Kagome had called her g-spot, she didn't understand until Sesshomaru mated her. "Ah! Ah—ooh! Yes, yes! Oh, Kami yes! Sesshomaru" She screamed at the top of her lungs. "I'm coming, ah-ah!" She screamed and shook beneath him. She arched her neck and submitted to him. She panted and laid submissive. She knew she couldn't come a fourth time so soon. Her clit was so swollen from his grinding and touches, it was also so sensitive.

"Rin!" He growled with a long howl. His head came down and bit into her flesh, into the mark. His body shook above hers as he thrusted into her and came deep in her again.

She wrapped her arms around him and sighed in content. She kissed his shoulder since they were right before her. His face buried into the crook of her neck. He was sucking on her mark and licking it gently. Dog demons was her only explanation. She liked it though, his tongue licking all over body. She particularly liked it when he licked between her legs. He would normally growl, spreading her thighs and dove in between her legs, letting her grind against his face.

She shook the thought from her mind and concentrated on feeling him. He was finally relaxing, claws retracting. He shifted and pulled out of her. She sighed softly at the loss.

"I believe the entire castle knows that we belong only to each other. No other may look upon you nor any be so audacious to try and bed me." Sesshomaru huffed out and let Rin pull him down for a kiss.

"Hm. She asked then?" Rin questioned him with a raised brow.

"Her scent asked. Perhaps her and Lord Aito should be matched." Sesshomaru rolled them onto their sides. He rubbed her hip and then leaned over and licked it slowly and gently. "Since they clearly need to both be bedded." He added after his ministrations.

Rin shook her head. "Aito is still a pup in many ways. He is not much older than me, while Lady Izumi is a whore in many ways she lacks the emotional capacity to care for more than a quick affair."

"Is this your counsel then?" Sesshomaru asked.

"Yes, they are not a good match." Rin stretched onto her back and arched her back up. She felt claws grab and massage a breast, careful of piercing her skin. She playfully smacked his stripes on his wrist. He withdrew his hand and huffed.

"Then what do you suggest? We need better trade and we need them out of our castle. They have overstayed their welcome." He said and laid on his back beside her. She rolled on her side and he glanced at her. She touched the indent on his hip, half of the 'V' on his lean hips. Lean hips that perfectly fitted between her spread thighs. She moved her fingers up along his ribs and then down onto his lower chest. For someone so fluffy in his true form, he was pretty hairless before her. Only a trail of soft silver hair led down from his navel the source of her greatest desires at most times. She moved her hand to his heart instead and traced patterns there.

"Let's see. Lady Izumi desires spices of the east. She lives in the East, so marry her close to home and strengthen her stronghold there. Her subjects like her, despite her looseness." Rin said and heard Sesshomaru grunt at the last bit. In agreement or disapproval, she did not care. It was probably the former as she felt his arm snake around her and rubbed her hip.

"Hm. There is Haru. Give him some land and he can receive title of 'Lord'. He served Mother's family for generations; his loyalty is true." Sesshomaru said and Rin nodded.

"See, an excellent match." Rin smiled lazily in the warming afternoon.

"Hm. Lord Aito?" Sesshomaru asked her.

"Let's send him to your mother at the Palace in the Sky, so that he may learn proper court etiquette." Rin kissed his cheek. She was even bold and let her tongue flick out and lick the stripes. She got a reaction of a small shudder. Claws gently scrapping her skin. Dog demons. They lived in his father's estate since it was easier for most demons to reach. It also meant Inuyasha, Kagome, and the other could visit more easily than the other palace.

"Mother may beat him several times over if he is caught spying on her." Sesshomaru chuckled.

"Really? I thought she might teach him things. He is a young handsome dog demon after all." She received a growl. She cupped his face and kissed his jagged stripes down to his snarling lips and pressed carefully against his fangs. He simmered down and pulled his claws from her hip. "Sesshomaru is my Sesshomaru and there is no other and there will be no other. I made a simple comment. My apologies." She smiled and let him go as he shifted. Muscles stretching as he leaned over and licked her hip again, laying gentle kisses in apology for his reaction. "Such soft kisses from such a deadly lover."

"Lover?" He pulled her to sit with him. They had rested enough. He cupped her face, "You're my mate."

"Can't I be both?" She asked, lowering her eyelids, brown orbs glittering from the sunlight filtering through the open door to the garden. She pouted swollen, full lips and received a gentle kiss. She had grown pretty, lovely and fair, and other words had been tossed her way.

"Yes, that suits my needs best." He smirked. "Now, perhaps we should go to the baths and that annoying runt of his pack will not try and spy. Or else…" A feral look grew in the depths of his amber eyes.

"Or else what my lord husband?" Rin hummed out, ideas running through her head as surely as they were in his mind.

He leaned close to her, whispering in her ear, breath fanning on her skin hotly, just like his words, "I put you on all floors of the onsen and fuck you hard until he scampers off with his tail between his legs. He will know who my Rin belongs to." He nipped her earlobe gently and she shivered. She could feel the wetness gather between her legs along with all their activities.

"Let's go bathe then." Rin smiled and swiftly disengaged from his hold and grabbed a yukata.

"After the bath we must check on the children." Sesshomaru reminded her.

Rin laughed as Sesshomaru grabbed a yukata and tied it loosely around himself. The baths were part of the region of their chambers. "Poor Jaken, saddled with babysitting duty while we dealt with the guests." Rin laughed out as she walked to the open door and waited for him. He walked up to her and placed a hand on her lower back.

"I trust Ah-Un more with Towa and Setsuna than I do Jaken. But they are only two summers old, Jaken should manage." Sesshomaru said and they both stopped as they saw their raven-haired daughter, Setsuna, walking about down the porch.

"Or not." Rin laughed and walked up to their youngest daughter. "Setsuna, you clever girl, did you escape Jaken?"

"Mama! Papa!" Setsuna called softly and snuggled into Rin.

Sesshomaru walked down the porch and turned into the open doorway of the children's room. "I see." He said simply and walked in.

Rin raised an eyebrow and looked at her daughter. Amber eyes looked at her and Rin smirked. She quickly padded down the porch and turned into the room and laughed lightly at the image before her. Rin looked to Setsuna and saw a small smile. "Naughty girls. Mommy and Daddy had meetings this morning and here you two are…"

"Tying up Jaken." Sesshomaru finished and swiped his claws at the make shift ropes made from a torn sheet.

"Are you alright, Jaken?" Rin asked with an amused smirk.

"Milord, Milady…your children are devious, little…" His eyes grew wide as he saw the smile form on Sesshomaru's face. Death was eminent, "darling pups! They passed their lesson. How to make ropes and tie up an innocent retainer!" Jaken said quickly.

"We'll take them now, Jaken. Organize and prioritize the scrolls." Sesshomaru ordered and picked up Towa.

"I want to play." Towa pouted and pointed down at Jaken.

"No more playing. You did well. Come, time for a bath." Sesshomaru said and followed Rin out of the room.

"Play in the bath?" Towa asked.

"Yes, swim in the bath." Rin smiled.

Jaken fell back onto the floor and sighed in relief, he was spared a beating by quick thinking. His lord's weakness was no longer his new lady, Rin, but the children. Compliment the children and you would be spared. He nodded to himself at his theory.

The truth was that Sesshomaru only spared Jaken for the moment because he did not want to commit violence before his children at such a young age. He would be Jaken much later, once the girls were asleep for the night.

Sesshomaru is a bit possessive, isn't he?
