….

The small demon gulped, looking up at the once not-so-large human. Never did he foresee this happening, nor did he think he would want this so much. His cock was hard in anticipation. The large human showed her lusty smile. She too had been unsure of this, but something about it had made her all wet, or so she told him. Both nude before each other, he thanked whatever had done this to him. His eyes skimmed down her body, down to her wet, dripping folds. Eyes glowing, he was ready to begin.
….

Early that day, Sesshomaru and Kagome had just finished romping around in the woods. While Sesshomaru loved how it felt with her, there was a strange feeling that there was something more he wanted. Every time he would finger her, feeling the warm pulsing in her pussy, or that same feeling on his tongue or member, it was as if it wasn’t enough. It was as if he wanted to feel that same feeling… all over him. He never spoke to Kagome about, not being sure what she would think of that. In his spare time though, he would just close his mind and imagined it. Of course, this would always cause him to have an aching hard on, and soon he and Kagome were rutting again. If only he could feel that just once, he thought. 

The day went on like usually. Rin and Jaken followed Kagome and Sesshomaru towards the edges of his domain. With Naraku gone, things had gotten a lot quieter. This had reminded him… Kagome had asked him a question about something he never thought of. Lord of the West, yet he didn’t have a place to live. He found no reason to have a home; he could just lie under a tree if he needed a place to rest his head. However, with the entourage he had now, it would be good to have one. I would really be good for Kagome and Rin. Both could become ill quite easily, unlike to Jaken and he who did not become ill. 

Remembering back when he was young, he recalled that his father had had a small home for them once. Then, after his mother decided that she would choose her duties over his father, it became an escape for Izayoi. It was a vague memory, but something about being under that roof with his family was nice. 

Deciding, he told Kagome and the other he’d be back later. After that, he flew off to find the best artisans and the like he could find. Just in case, he also stopped by Totosai’s home. He may have been a weapon’s crafter, but he might have known someone he hadn’t.
…

Masking their scent, a figure hid in the bushes near Totosai’s hideout. It had been a demon that had defeated by Sesshomaru long ago and had luckily survived. He still cursed the loss of it, and especially his tail. He had the perfect panther tail; so nice and soft. He would clean it six times a day. He actually used it to impress ‘the ladies’. Now, there was a small stump where the long appendage once was. 

Now, he would get his revenge! Opening a bag of strange dust, he whispered a spell upon the dust, in which he learned from the one that had sold it to him. The wind suddenly picked up, and the dust followed it. Circling itself around Sesshomaru, the panther smirked. “Half the size, half the power.” The panther ran off, pleased with what he had done.
….

Sesshomaru had smelled something odd on the wind, but ignored it, as he had work to do. Each day, he would check on the progress of the new home that would be his and Kagome’s. However, each day he found himself noticing changes in himself. At first, he thought maybe he wasn’t getting enough rest. It was hard to make sure he kept the new home a surprise, and he slept very little since. Now he wondered if something was wrong.

First, he noticed his hearing was a bit off. He should have been able to hear at least across the forest before him, but now he could only hear ¼ of the way. Next was his sight. Having excellent perception of far away landscape, now it seemed he could only see as far as the building of his home, if he came out of the forest clearing, which hadn’t of been that far. Last he noticed was his demonic senses. Everything about himself just seemed weaker. 

‘Perhaps I should get rest.’ The house was complete, all but for furniture. Totosai had showed up, so see how well it was done. Taking the opportunity, he asked Totosai to go get Kagome and the others. 

The workers had left, so Sesshomaru went inside to one of the large rooms, before falling fast asleep. 
…

Sesshomaru awoke later to the loudest booming sounds he had ever heard. He quickly shot up into attack position, eyes glowing red. He saw no one; but what he did see was more of a surprise than anything else was. Suddenly, the house looked a lot bigger than it had. Turning his head upward, the wall looked to be the size of a mountain. For the first time, he said something his half brother would say aloud.

“What the hell is going on?!!?!?!”

The booming sounds grew louder, and soon giants walked within the room. He got ready to pounce, only to see those giants were Kagome and the others. They looked to be searching around the room for something, starting to look worried.

“I can feel him in here, but I don’t see him,” spoke Kagome.

They must have been talking about him. Jaken started jumping up and down, shaking the floors below him and taking him off his feet. If he didn’t make them aware of him soon, the imp would surely get his pay back for all the years he used Jaken as a punching bag. Then, he got a great idea. Pulling out Bakusaiga, he jumped up as far as he could and used his mighty attack against the wall of the room. Turning towards the others, he found his idea to be right.
Rin, who noticed any little thing, had surely noticed him making a gash in the wall. He watched as she gasped.

“Lord Sesshomaru!!!??”

All turned to look where she had. He quietly groaned then. He didn’t think about the now interrogation he would have.
…

Sesshomaru and Kagome sat on the floor of their soon-to-be room alone. They had both been lost in thought about the situation. An ideal flashed upon Kagome’s face.

“I know! I’ll ask Kaede and Sango. Since Kaede is Sango’s midwife, they’re both in the same village. They should know something about this.”

Sesshomaru nodded in approval. As much as he’d hate anyone to see him like this, those two women have great knowledge in thing. Even the perverted monk might know something. 

“Very well. We will head out on Ah~Un tomorrow. For now though, we might as well rest here. After all, this was made for us all to live in.”

Kagome smiled down at her love’s form. He had a point. Not to mention Rin probably needed this rest in a nice, comfortable bed. 

“All right then. Tomorrow.”

Deciding she should probably lay down herself, she started to get up for bed. She stopped herself, noticing the strange look on Sesshomaru’s face. Was it…embarrassment?
…

He did pay attention to the whole conversation, but a thought kept crawling back in his mind. Being in the state he was, one would think he shouldn’t be so horny. Nevertheless, those thoughts that had been appearing in mind’s eyes kept popping up throughout the conversation. That pussy of hers…

His cock twitched at the thought. How would it feel? Would it be like he imagined it? He felt embarrassed at just the thought of it. 

“What is it,” he heard her ask.

Could he tell her? Gathering up the will power, he mumbled out what he was thinking.

“What was that? You’re going to have to speak louder. It’s already hard to hear you,” she replied.

“Well-I…I meant to say… Kagome, would it be troublesome to ask you for a favor?”

This peaked Kagome’s interest. What sort of favor would he want? She had never seen him act like this. “What’s the favor,” she asked him.

Swallowing hard, he finally choked it out. “Kagome, there is a great longing I have had for quite sometime now. I’ve wanted to feel you from the inside, not just with my cock. With my whole being, I want to be within your pussy, feeling the wet warmth all around me.”
…

Kagome blinked more times than she could count. He wanted what??? She started to pour out reason why that could be a bad thing. The more reasons she came up with, the more he found ways to reassure her. It was a little on the weird side; but, it wasn’t like he was asking for something like a threesome. He just wanted to see if it would feel as good as everything else would. The miko knew he could see her nervousness and worry about it. 

“A-all right, Sesshomaru. I guess we can give it a try. But if you don’t like it, or if something feels off about it while you are in there, I’m pulling you out. Agreed?”

Sesshomaru nodded. “Agreed.”

Gulping slightly, they went over on the best way to do this. She even contemplated how she would have to get herself wet enough for him to slide in easily. He even suggested putting him in her mouth to cover him with saliva, and then putting him in. ‘I’ll only do that if I can’t get wet enough,’ she thought, not too fond of that idea. What if she accidentally swallowed? While she didn’t really expect that to happen, she really didn’t want to take any chances. Even her swallowing him completely would end badly. 

Both of them undressed. As Kagome finished taking off the last piece of clothing, she looked down to see Sesshomaru sliding his hands slowly up and down his shaft. He was nervous too. At least she could tell that. Knowing he felt similar to her was sort of a blessing. That means they both would be taking extra precautions. 

Watching him stroke his member usually would arouse her; but tonight it looked cuter than anything. An itty bitty Sesshomaru with a hard on. Something about that made her want to giggle. Instead, she tried to keep herself in the mood. Looking over his body, her hands slide up her stomach. She began playing with her breasts. Rubbing the large mounds, her finger circled her nipples, making sure not to touch them. 

The effect of a large Kagome actually was making Sesshomaru more lustful. Especially how she began to look at him while playing with her breasts. He groaned, rubbing a little faster on his member. 

“Kagome, please play with your nipples,” he spoke loudly. “I want to watch you do that.”

Kagome complied, as she started rubbing them. She moaned softly, as she squeezed the tips and pulled at them. Listening to his groans and seeing him rubbing himself more brought out more lust within her. She could feel as her fold was starting to get wet. The want for something inside of her was growing, the more she played with herself. Bringing one hand down, she circled her folds with one finger. Suddenly, she pushed her index finger with her and began to pump. ‘Perhaps this won’t be a bad idea,’ she thought. 

The miko began to think about how it would feel to have his full body within her turning and wiggling, rubbing against her from most likely all angles into her sides. It made her hotter. She soon inserted yet another finger, just to try to appease her thoughts, but it wasn’t enough. She looked down at him, licking her lips. It was time.
…

Noticing the gleam in her eyes, he knew she was ready for him. He was even happier to see that she seemed to want him within her. Walking over to her, he waited for her to slide her fingers out. 

He raised a brow, trying to figure out how to go about this. ‘I suppose I should test this first,’ he thought. Lifting his arm, he slid it between her folds, feeling the pulsing warmth around it. ‘Nnnn. It’s wonderful,’ he thought, a fang sticking out of his mouth. Using his hand to grasp the side of her, he slipped in his other arm. Then his pushed a leg slowly in, and then the other. Soon after, he was pulling himself in. The heat and pulsing around him was delightful. He could hear Kagome whine and groan, as he went in slowly. As much as he wanted to hurry up, he had to admit it was difficult to pull himself in. Much to his surprise, he felt Kagome’s index finger on top of his head, helping him to go in. It was both shocking and somehow very pleasing that she did so. 

Soon, warmth was completely around him. The sounds of liquid slapping around him and the movement of her pussy’s insides are all that he could hear. His eyes were closed. He could feel air coming in, from Kagome most likely keeping her folds open. They had discussed that, so they would both know he was getting air. He squirmed around, trying to get into a better position. That’s when he felt the vibrations; her moan rumbled throughout her, making her wet insides squeeze him a bit. It wasn’t enough to hurt him, and it was very enjoyable to his bodies. If he had any aches or pains, he was sure this would rid him of them. Even more, was just the comfort of it all. 

‘This must be how a child feels in the womb.’ 
…

Kagome’s head fell back, while she held herself open. All that squirming really did feel wonderful. If he continued to squirm like that, she wouldn’t be able to keep herself from cumming. That was what they were worried about. Would her body squeeze him too hard, if she came? Or, would he be pulled in far and have difficulties coming back out. Perhaps he would just flow out, along with her sexual fluids. The feeling became too great, as his body pressed hard against one of her sides. Kagome called out his name in both worry and pleasure.

Sesshomaru felt his body squeezed, making him cum within her. Warm fluids were pushing him out of her. Before he knew it, he was sliding on the floor outside of her. He opened his eyes, after wiping as much of her cum from his face. He groaned, now being out of that comforting warmth. He watched Kagome’s face change from pleasure to worry to relief. 

Kagome was glad to see his was all right. She picked him up while she panted. 

“You were wonderful, my love,” she told him.

“So were you,” he replied, a smirk rising on his face. 

The miko placed the small demon upon her chest. Both laid there still panting. No longer did they feel like this was a bad thing anymore. Sesshomaru, in fact, wanted to continue doing this until he is returned to his normal form. 

‘This will most likely be the best thing about being this size,’ thought Sesshomaru, before he fell fast asleep on top of Kagome.
