Sesshomaru's Demon

(A/N Lemon)

"If you are sure you want me then I choose to be…" She trails off with a smile, looking at the ground, "I choose to be your mate." She looks up when she feels his aura blast out and sees that his markings have grown jagged, his eyes have turned red and teal, and his teeth and claws have extended. "My Lord, have I made you angry?" she asks in concern as his demon suddenly grabs her and pulls her close.
"No," With that he seals her mouth with a rough kiss. "MINE!" he claims as he starts to nuzzle her hair and neck.
"Lord Sesshomaru?" She asks, "Are you okay?" she was confused as to her loves response to her decision. "Oh… You are the demon side aren't you?" She asks realizing what was happening.
"Yes, and I don't want to hear you calling me Lord anymore." He snarls. "I am just Sesshomaru to you now." Don't scare her. Duh. "Rrrin," the demon part purrs, "You are mine now." He smells her arousal rolling off of her in waves now. Her face holds the largest smile he has ever seen and total happiness is in her eyes.
"S-Sesshomaru," She starts with a blush "what-how do I…" She looks so confused on what to do next. Then she shocks him by pulling him close and kissing him. He freezes and then when she starts to pull away thinking he didn't like her kiss, he jerks her back and pushes them back against a tree. She gasps and he slips his tongue into her mouth and starts to explore this new area of her body, his hands slowly moving to cradle her head. Her head spinning from his response she shyly starts to touch his tongue with her own. His chest rumbles as he growls lowly at her shy attempt. Heat explodes within her as he starts stroking her tongue with his own, battling for dominance, that she immediately surrenders to him. She presses herself against him as she feels an ache in her lower abdominal area along with a wetness that she doesn't understand, hoping it will help somehow. They both moan and he pulls his mouth away and starts to lick nibble and kiss her neck. One hand moving to her obi, the other pulling her closer to himself. When her obi finally comes untied he sends it to the ground with a flick of his wrist, undoing the small ties that hold her kimono together, slightly exposing her chest and breasts. Her hands were running up and down his torso and tangling in his hair and mokomoko. She moans loudly when his hands graze her breasts as he pulls her kimono down to her waist. He pulls away slightly to see her breasts that were just large enough to fit into his hands. She slowly reaches down and starts to tug on his obi then stops realizing that his armor and swords were still on his figure. Putting her hands on his chest she pushes at him.
"Sesshomaru, your armor and swords." She reminds him gently when he growls unhappily at her pushing him away. He quickly pulls away from her and with her help removes his armor, as he removes Bakusaiga and Tensaiga. He pulls her close again claiming her mouth for a searing kiss that leaves both of them panting for air. He pulls away only to return to showering her neck and shoulders with kisses. He returns his hands to her breasts, massaging them and plucking at her nipples as they harden into pebbles. When she gasps and moans loudly he moves his mouth down taking one of her nipples into his mouth and swirling his tongue around making her moan and her hands clasp his head by his hair to her breast as her back arches into his mouth.
When he pulls away to switch breasts she moans loudly in protest at him stopping. And yelps when he starts on her other one. One hand was holding her close while the other was massaging the breast not in his mouth. He moved the one that was holding her to drift down her front to her soaked core. His fingers grazed her wet folds and he held back a moan at how ready she was for him. His erection was painfully hard and the feel of his silk pants was driving him insane. Suddenly Rin felt the night's air on her bare skin, and upon realizing she was naked she gasped, completely shocked at the realization of what was happening to her. She looked at Sesshomaru, "I don't- I haven't-Ummm…" she trailed off with a look of embarrassment and worry. "What do I do?" She asked looking adorable to Sesshomaru as she stood there naked and unsure of what HE wanted her to do.
"Do whatever comes to mind, I won't deny my mate anything she wants." Never shall she have to worry about what we want, she will always come first. Indeed. She shall have her hearts desires as long as we are mates.
"May I undress you?" She asked with a small worried smile. Her eyes showing her innocent embarrassment. At this request he lifted her hands and placed them on his obi, and showed her how to untie it. When it came loose she gathered it up, folded it, and placed it on his armor to keep it clean. He chuckled to see her treating it with such respect, "It will take all night if you undress me this slowly, Mate." He smiled a happy smile, "I can think of other ways we can spend the night continue more speedily." His chest rumbled in amusement as she smiled sheepishly and quickly moved to the ties of his hatori, only to be stumped with the mokomoko being in the way. "How do I move this?" She asked as she ran her hands up and over his mokomoko. She gasped when it lifted itself and moved out of her way. "Thanks." Her hands went to his pants and seeing the bulge she ran a curious hand over it. His growl made her jump and as she started to apologize he chuckled again and he rubbed up against her hand with a moan. She smiled and took her had from his erection to the ties of his pants, upon finding them she untied and slowly lowered his pants. As she lowered his pants she saw his penis jump free and pulse. Abandoning his pants she put both hands on it and was amazed at how hard it was to the touch, she also saw how large it was. That worried her. Where does that go? How does it fit into everything. He groaned when her hands hesitantly touched his manhood, and his hips jerked towards her making her hands slide up and down on it. His legs threatened to give out and he grabbed her pulling her up and slammed his lips to hers.
"What happens now?" Rin innocent asked.
"Didn't they teach you about sex?" he asked. At her questioning look he explained, "what happens between a man and a woman." She shook her head negative.
"Kaede always said that what happens between a man and a woman was not to be told until the wedding. It wasn't proper for a maiden to know what goes on between a husband and wife." She responded. How innocent can a human be? She was never told what is going on. I bet she is scared stiff with not knowing how or what to do to please me. I shall be gentle. I have to be gentle.
"I can tell you what to do or you can experiment and find what you want that way. It is your choice."
"Just tell me how to start." She said with shinning eyes.
"Let me," at that he brought them both to the ground beside their clothes and started kissing her mouth, followed by nibbling and licking his way down her body, pausing to grant special attention to her breasts, then moving downward to her black curls and hidden womanhood. His hands reaching it first and stroking her folds finding the jewel at the front and slowly running a careful claw over it causing her hips to jerk and her to groan, loudly. He moved one of his hands to cup her buttocks and the other found her channel and started to pump one of his fingers into it. She stiffened at the invasion, but soon was moaning and moving her hips at the same pace as his finger. He then inserted a second finger and started to scissor his fingers back and forth stretching her slowly. As her body adjusted to that his tongue flicked her hidden jewel and she let out a loud yelp of shock. When he started to move his fingers in time with his tongue her head started to thrash back and forth at the sensations coursing through her body. Her moans and panting escalating to small screams of "Sesshomaru, more please, give me more." She whined when he stopped and pulled away from her only to spread her legs and slide up her so his dick was even with her pussy.
"This will hurt at first." He told her gently, she nodded and when he started to push into her, her eyes started to water, "Sorry, Mate." With that he slammed his hips so that his manhood was buried all the way inside of her. She screamed in pain, but started to relax as she realized he was waiting for her to give the okay to continue. When the pain subsided she moved her hips experimentally and found the sensations unbearably pleasurable.
"I'm okay now" she stated as she started to rub her hips up against his, causing friction that felt wonderful to her. Sesshomaru started to slowly thrust in and out of her tight channel, but sped up when he heard her gasp "faster, oh please, faster." Her moans and groans came in time with his thrusts and she was panting, "more, faster, more, please give me more." He complied yet again to their delight then abruptly withdrew from her and asked if she wanted to try something that would please him more. She nodded, and he said "get on your hands and knees" she complied "what next?" He responded by pushing into her from behind, sliding over her sweet spot making her shriek with pleasure. She started to shove herself back onto him to make him go faster and was delighted when he went into demon speed. Her shrieks and screams were getting loud enough to hurt his sensitive ears, if not for what she was panting in them. "So…Good…More…Please…harder…faster…MORE!" and she came with her loudest scream of "SESSHOMARU!" He followed growling his release in the form of "RRRIN!" He then sank his canine teeth into the juncture between her neck and shoulder causing her to come again. He pulled out of her and cutting one of his fingers he spread his blood into her wound then licking the wound closed.
"What was that for?" she inquired.
"I have marked you as my mate for all the world to see and with my blood you have gained a demon's lifespan." He responded with a true smile.
"If Jaken saw that he would freak out." She pointed out with a full grin and started giggling at the thought of Jaken's face if he saw Sesshomaru's smile.
"Hn." Sesshomaru grinned, "your right."
"I think it makes you look even more breathtaking." Rin states as she cuddles into his chest with a yawn. "Night, love." She whispered as she started to doze in his arms.
Sesshomaru's grin widened when he heard her. "Goodnight, koibito."

(A/N Koibito means sweetheart, or lover, in Japanese)
