Before the Absence of a Lover
 
The Captain's meeting followed the normal agenda and the minutes sluggishly passed. There was the usual backbiting and point scoring with Mayuri sniping at Zaraki about some imagined slight. Toshiro was tired of the meeting before it had commenced. What was there to discuss? He was leading a mission into the human world to provide support for Ichigo. As yet, the only people he knew that were definitely going with him were Rukia and Renji because of their friendship with the deputy Shinigami.
 
Then the old man dropped the bombshell. “Captain Hitsugaya, I would like you to choose the final three members of the party. You will need to clear the choice with the relevant Captains, but I do not believe anyone would be foolish enough to disagree. I would counsel you to choose wisely and I recommend that you do not choose another Captain.”
 
Toshiro felt the blood drain from his face. “This is just great. None of the Captains will be pleased to have any of their subordinates taken from them, no matter what the reason.” He noticed a number of the people in the room shoot him looks of warning, except Soi whose eyes seemed fixed much lower than his face. He had avoided looking at her until now and had to quickly re-arrange his Captain's coat when he saw the direction of her gaze. Just a look and he got hard, thinking about how they'd fucked before the meeting and how good it had been.
 
From being used as sex toy, and now he would admit that had been his role, she'd actually asked him to fuck her and she'd enjoyed it and wanted more. When she made the new suggestion there was little chance he would say no. While the meeting went on he found it difficult to concentrate, anticipating what would happen afterward, hoping she wouldn't change her mind. He wanted to get between her thighs and screw her until they were both unable to come anymore. Just thinking about it was enough to make this meeting even more meaningless than normal. He wiped his forehead, amazed at the sweat that was forming there, even though the day was not warm. His cock kept reminding him what it wanted to do; it was a pity it couldn't make the meeting end.
 
“Any further business?” Captain Yamanto asked.
 
Toshiro held his breath. This was usually the time when all the arguing started but for once no one said anything. The silence lengthened.
 
“Then I will provide the final comment. The mission leaves for the human world tomorrow.” Toshiro felt as if he had been struck, he'd hoped for at least another day. He quickly glanced at Soi to see her face fall in disappointment. She wanted more time with him; at least he hoped that was why she seemed unhappy. “Captain Hitsugaya, will you remain behind for some final instructions?”
 
He nodded, knowing the instructions would be lengthy. The other captains left and Soi gave him a quick glance as she left. She mouthed `one hour?' and he nodded gratefully. One hour would pass, eventually. It had to pass. Time didn't stay still, except during these thrice damned meetings.
 
He tried to pay attention to the old man's advice, restrictions, prohibitions and instructions but his mind refused to concentrate. Perhaps his mind wasn't completely to blame. He agreed, half listening to some of the matters being outlined and then Captain Yamamoto asked, “Who else will you choose? I think you should clear it with me now, just in case you have any difficulties.”
 
His mind had been elsewhere because he stood there, his mouth open as he tried to think. Renji was going and he remembered who he was good friends with: “I will request that Ikkaku Madarame joins the mission. He has fought Ichigo and they became friends, I think. He is friends with Renji and the two of them would provide solid support.”
 
“If you choose him, I suggest you also select Yumichika Ayasegawa as well. Those two work particularly well together. I do not believe that Captain Zaraki will be pleased and you should ask him for his agreement,” the Captain-General was not advising, he was ordering.
 
“Yes, sir. I will make certain he is informed,” there was no way on Earth that he was going to chase after Zaraki. Anyway the man would probably be having his bath, and everyone knew only stupid or suicidal people would interrupt that Captain's bath.
 
`See that you do. And the third candidate?” For a moment Toshiro thought of nominating Soi, but he wanted her here to protect Momo and it would seem strange to nominate a Captain especially since he had basically been ordered not to select another Captain.
 
“I still have yet to decide. I will let you know soon, Sir,” he temporised.
 
The old man nodded. “I'm sure you have much to do. Good luck Captain Hitsugaya. I'm satisfied you accepted this responsibility.”
 
Toshiro bowed slightly and left the room. Now he could meet Soi. He hoped she would be interested in more than one screw because the images that had passed through his mind made him believe that once would only be a taste. As he closed the door behind him, he felt a pair of well known arms embrace him and ruffle his hair. “I'm going to miss you so much when you're gone, Captain.”
 
“Matsumoto, leave me alone. I know you're teasing, but I'm tired of it. I have a job for you; you know, work,” he may as well make her do some work for a change.
 
Her large eyes looked at him, shocked. “Work? For me? What have I done to displease you?”
 
He choked back a laugh at her pretence of innocence. “I want you to ask Captain Zaraki if he objects to Ikkaku Madarame and Yumichika Ayasegawa accompanying me on my mission. I want you to get the answer. It's urgent, but don't be stupid enough to interrupt him if he's bathing.” He was rather surprised at the unusual expression that crossed his Lieutenant's face. For a moment he could have sworn he saw a spark of interest in her eyes. Dismissing the notion he continued, “I'll meet you in my office in two hours. Make sure you have an answer for me.”
 
Without another word, which was also abnormal, Matsumoto nodded and left, smoothing her hair as she went through the door. For a second he felt a strange foreboding, but shrugged it off. She'd be sensible, he hoped. If she wasn't he'd have to remind her of her position as his lieutenant. She hated the reminders, becoming solemn and irritable, but she did listen and try to comply, for a short time.
 
Noting the time he saw he had ten minutes before the hour had passed. He moved as swiftly as he could to the place they had met for the last two weeks. Entering the room he saw it was deserted and felt apprehensive. Soi might have changed her mind and decided that the pact was broken and she didn't want to renew it.
 
He licked his lips, wishing for the taste of her in his mouth, the sound of her sighs as he licked her, feeling her respond to his tongue. Hell, he'd even go back to just servicing her with his mouth now. He pictured how she looked, naked, her knees bent; her thighs apart as she demanded he pleasure her. For the last week he'd enjoyed bringing her to orgasm, even though he went through the ritual washing. Why was he even thinking like this? It was over.
 
The door opened and Soi entered, looking unexpectedly shy. She closed the door and locked it, but then stood uncertainly, glancing at him, but refusing to look at him. He found he felt shy too, but so damned horny he wanted to fuck her against the door.
 
Minutes ticked by. His cock was getting harder, just knowing she was in the room, but she still seemed to be entranced by the pattern of the floorboards, her face pink and her mouth open, just a little, as she refused to meet his gaze.
 
Tiring of the impasse, he removed his coat and dropped it to the floor. She copied him. He undid his shirt and it quickly followed the coat to the floor, then his hakama, then the rest. Soi copied everything until they were both naked, standing metres apart in the room. Her eyes had moved from the floor boards and seemed to be firmly fixed on his cock while his gaze strayed between her chest and the fine down that covered her sex. He stifled a groan as he looked at her, wanting her to come to him, to acknowledge that she wanted him.
 
Giving up, he lay on the bed and let his hand descend to his cock as he shut his eyes. What could he say to her? She had been in control of all the sex until now and he wanted to assert his authority, or at least be a partner in the decisions.
 
A hand shyly touched his penis and he opened his eyes to see Soi standing next to the bed, a look of near fear on her face as she touched his cock then quickly jerked her hand away, indicating that she was scared of what it might do. Toshiro realised she had not completely lost her fear of men, but he thought she was trying to force her acceptance of him. Her face was a mixture of confusion, disgust, longing, desire and fear but he could only respond to the longing and desire.
 
Without thinking any further, he reached for her and dragged her on top of him, his lips eagerly seeking hers. She resisted, but as soon as her body came in contact with his, her mouth opened and she was kissing him in return. She pushed her mound against his cock, rubbing it between their bodies, a direct contradiction of how she had acted when she touched him with her hand. Feeling the fine hair and her skin touch him in this way he almost pushed her onto her back and penetrated her, but that would be cheating.
 
Her tongue knew what it was doing. She licked his lips and then caressed his soft palate and gums. She did not even touch his tongue with hers until he was unconsciously thrusting against her. The movement made her break the kiss.
 
“Lick me,” she commanded as she had many times before. Pushing her onto her back he deliberately misheard her and began to kiss her shoulder lightly, hoping she would ask for something more. He wanted her to treat him differently to the way she had the past two weeks.
 
“Lick me,” she demanded, her voice torn between confusion and anger.
 
Shrugging he moved his head down to her breasts, tracing his tongue from one to the other, not sucking, just licking. Her skin tasted different and she smelt of soap. She'd demanded he lick her and that was what he did. He licked her breasts, her nipples, her stomach and her nipples again, taking his time and varying between soft and gentle and avid and lustful. He liked her breasts. They were small, but well formed and he noticed that goose bumps were forming where he licked. The skin on her breasts felt different to the firmer flesh of her stomach.
 
“Toshiro, you're not listening. I said lick me,” her voice did not sound as assured as normal but the tone was lower indicating that she didn't dislike it.
 
“I am licking you. You weren't specific,” he said running his tongue over her nipples again and again. She stiffened underneath him and he wasn't sure if it was anger or something else. Her nipples were pink and erect and he wanted to take one in his mouth and suck it, but she'd only asked him to lick her.
 
“I meant lick me, make me come,” the demand was wavering as her nipples became even more erect and seemingly demanding of his tongue.
 
Ignoring her words, Toshiro moved up her body and kissed her mouth to prevent any further demands, careful to keep his lips gentle on her but she pulled her mouth away.
 
“I thought you were going to do what I said.” She looked a little worried at his ability to act independently but her eyes kept straying downwards which made him hope.
 
“Everything's changed Soi. I thought you realised that. The agreement is that we will have sex, not that you will be in charge, and having sex is more than just licking you as I have. I have an idea. You tell me to do one thing and I'll do it. Then I tell you one thing and you do it,” Toshiro was trying to compromise. It was better than just giving into her demands and maybe he could demand that she allow him to touch her breasts, the different parts of her body and he could experience that intimate contact.
 
Soi looked even more puzzled and unhappy. “You ask me to do something? I don't like the sound of that. You might ask me to lick your thing and I don't want to.”
 
“You expect me to lick and suck your pussy. Why won't you lick my cock?” This woman had some strange expectations and he wasn't happy that she always referred to his penis as a `thing'. It had crossed his mind he would enjoy watching her tongue lick his cock lingeringly but her words made him discard that fantasy.
 
“Because it's a man's thing,” was the only answer she gave.
 
“But you like me fucking you with it,” Toshiro pointed out. He was beginning to wonder if this new agreement would work out at all.
 
“I liked it the only time you did it. I might not like it the next time,” she snapped, angry with his obvious pride in her enjoyment of having sex with him.
 
“Okay, okay. I won't ask you to lick my cock. Will that make you happy?” Toshiro was prepared to concede that point.
 
“If you lick me now, and I don't mean my breasts. I want you to lick my clitoris,” Soi said, a little more assured.
 
Toshiro shrugged and moved down, between her parted thighs. He would indulge her in this because he wanted to. Slipping his fingers between the close curls, he exposed her labia and began to lick her cunt. He could barely taste his cum from the earlier fuck, but he was now sure she had bathed. He could taste her. He thrust his tongue into her a few times wishing it was his penis and hearing her sigh, he moved his attentions to her hot centre, licking her the way she had told him she liked best, slow interspersed with fast. After a minute he drew his mouth away from her and sat up. Her eyes opened mystified and dazed and she stared at him again not understanding. It was hard for her to adjust to the change in their agreement.
 
“My turn. I want you to kiss me on the mouth and use your tongue,” he demanded. He really wanted to ask her to touch him, but it seemed unlikely she would agree. She had kissed him earlier.
 
Soi sat up slowly and brought her mouth to his; kissing him with the expertise she had shown previously. He wanted the kiss to persist but Soi broke it after he was starting to draw her closer his excitement focusing on how she could arouse him so easily with her tongue. She made her next request. “Suck my breasts.” She lay down, her eyes shut, expecting him to comply.
 
Toshiro swooped down eagerly, drawing the erect nub into his mouth. He'd been waiting for this request and was rewarded by a soft sigh of pleasure. “I like that,” she said as he increased the pressure and licked her with his tongue as he felt her strain against him. He let his lips rove over the warm flesh, teasing her, pulling the skin between his lips and gently sucking and then moving back to the nipples until she was sighing regularly and he noticed her legs had parted slightly, whether voluntarily or involuntarily he did not know.
 
That was enough for him to stop. “My turn. I want to fuck you until we both come,” Toshiro demanded, finally giving into the demands of his body.
 
Soi did not reply. She lay back and parted her legs further, obviously waiting for him to start. This time he did not hesitate but plunged straight in, wanting to feel her tight walls enclose him once more. The smooth muscles surrounded him and he sighed in pleasure at being within her body once more, having thought of this moment all through the Captain's meeting. She jerked against him as he penetrated her and he looked at her, noticing her eyes were tightly shut. He stopped moving, wondering what was wrong.
 
“Why did you stop,” Soi asked, staring up at him questioningly when he stopped. She was moving very gently under him, tiny motions as if she were trying to push herself onto him further.
 
“You jerked against me. I thought I'd hurt you,” Toshiro explained, ignoring those subtle pushes that were arousing him. He hoped they were evidence that she wanted him to continue because if she wanted to stop now, he wouldn't know how to react.
 
“Maybe for a second, but I like the way your thing fills me. Could you move now, fast? I only have an hour or a little extra and I want to do this more than once, if we can,” her candour shocked him slightly but he found her words exciting.
 
Nodding at her request he began to thrust into her, slowly at first, needing to feel her pussy clutch at him as he moved into her. The first time they'd had sex the way the muscles had gripped him was a surprise. He hadn't known it would be like that, the slick feel of the muscles massaging his cock as he pushed into the heat that surrounded him Sighing he increased his speed as he felt her response . Her hands were now on his back and he felt her pulling on his shoulders and she brought his mouth to hers.
 
There was no hesitation in returning her kiss. He yearned for the method she used when her lips moved on his and her tongue teased its way into his mouth. He'd once tried to kiss Momo, but she had laughed at him, telling him that his mouth was too wet. Soi just kissed him and he was glad that instead of instructing him how to kiss, she showed him. She circled his gums and then touched his hard palate with swift flicks.
 
When the kiss was finished, he pushed her legs further apart in an effort to penetrate her deeper. She complied and then wiggled a bit to find a more comfortable position. The wiggling almost undid him, providing a new sensation that he wanted to explore again. He stopped, “Do that again,” he said.
 
“What?” Soi asked. “Kiss you?” Her eyes were only partially opened and he saw the coloured irises moving behind the half shut lids.
 
“Move like that again,” Toshiro instructed her.
 
“No. If anyone has the right to make a demand it's me. I didn't want you to stop and you did. I told you I only have a short time and I'm close. Make me come.” Soi was again making those subtle little moves that made him forget his request. The subtle moves were becoming less subtle and more erotic as she rocked her hips against him.
 
That move was even more stimulating than the wriggling and Toshiro stayed still just to experience how her cunt worked on his cock. As a reflex to her actions he pumped into her, grinding his pelvis into her, his hands gripping her thighs tightly, as he felt the first signs of his impending orgasm.
 
Soi became rigid underneath him and he thought she was holding her breath. Not certain, he was about to ask her if she wanted to stop, he felt her vagina grip him tightly and then spasm around him. This time he knew what was happening and thrust into her harder, wanting to fully experience the sensation this time. His mouth opened wide as he felt his climax overtake him, trying to prevent the yell he wanted to make, as his seed left his body.
 
After the few seconds he required to get his senses back he looked at Soi to see her looking at him the same way she had last time. Again he felt abashed at her scrutiny and hurriedly withdrew, lying down beside her.
 
“That was better than last time,” was her unexpected remark.
 
“Yes, it was,” Toshiro replied without thinking. “I wish I didn't have to leave tomorrow.” He bit his lip, quickly understanding how revealing his last statement had been.
 
“You could ask for me as one of the members of the mission,” Soi began.
 
“I thought of it, but it won't work. You promised to watch over Momo and the Captain-General said he only wanted one Captain,' he kissed her, again without thinking what he was doing.
 
For a brief second he felt Soi tense against him, but she returned his kiss. `I hope that means you want to do it again,” she remarked, one eyebrow raised as she looked at his cock.
 
Toshiro tried to explain. “I do, but I can't, not yet. I've already come three times today. Men are different to women. We have to wait until we can get erect again.”
 
“Why? It seems silly to me.” There was a tinge of disappointment in her words.
 
“That's just the way it is. If you sucked me, it might make it happen faster,” he said knowing what the response would be.
 
“Suck your thing? Never. Why would I want to do that? I told you earlier that it wouldn't happen,” Soi's expression showed her repulsion at the idea.
 
“That was licking, not sucking. Well, you could touch me instead, that might help.” Considering her reaction to touching it earlier he didn't hold much hope that she would be prepared to do that either.
 
“Touch that? Isn't there anything else I can do?” Soi seemed torn between desire and fear and he could appreciate the conflict she was experiencing.
 
“I don't know. Why don't you think of something?” If she made the choice he couldn't be blamed.
 
Soi looked at his body and his face. Quickly her head moved and her mouth engulfed his right nipple. The sudden pressure made him jolt as she started to suck it, hard and fast. His cock jerked in response at the unfamiliar but arousing sensation. Her mouth was hot and her lips felt strong as they tugged at him, but he wondered why it was so exciting. It dawned on him that she had done this before, but he didn't care as she applied more pressure.
 
She switched to the other nub and licked it before applying a similar pressure. Her mouth was making him hard and he felt her hand move downwards to tentatively touch him. As soon as found he was erect, her hand was swiftly removed, as was her mouth to his disappointment. Without waiting for her demands he mimicked the way she had treated him and soon she was sighing heavily, and demanding that he make her come.
 
This time he tried to make it last, thinking it might be the last time he would have a chance to screw her until he returned. Soi complied for a little while as he sucked her breasts while fully penetrating her, but soon demanded that he move faster and encouraged by pushing onto him when he seemed about to slow. When they were once more lying quietly, panting almost in unison, Soi let out an exclamation and quickly got to her feet, washed and dressed. “I'm late. We'll meet here when you return from the mission. Don't worry about Momo; I will make sure that she is safe.” She hurried out the door and Toshiro felt a strange pang when he realised she hadn't kissed him good bye.
 
Tiredly washing and replacing his clothes, he left the place as cautiously as he could, realising that Matsumoto might be waiting for him back in his office with the response from Captain Zaraki. As he walked through the streets he noticed one or two passers by look at him and smile. He did not smile in reply but opened his office door, only to find it empty. Sitting at his desk he applied his mind to the neglected paperwork, wondering why his lieutenant had not yet returned from her simple task.
 
Hearing a knock at the door, he answered it only to see Ikkaku Madarame standing there. “Captain Zaraki urgently requests your presence at his house, Sir,” was the disturbing request.
 
“I only need his need his verbal agreement. I have other duties I must attend to before I leave tomorrow,” Toshiro was not pleased to be summoned in this fashion.
 
“I must insist, Captain Hitsugaya. It involves your Lieutenant. I think you need to visit my Captain as soon as possible before the situation gets out of hand,” Ikkaku implied some dire consequence and apprehensive at the range of possible problems that his mind created, Toshiro agreed. Ikkaku bowed and left.
 
Overhearing snippets of conversation on his way to the 11th Division compound, and being mindful of the brief message from Ikkaku, Toshiro dreaded what he was about to hear. Once again, his Lieutenant had disregarded a direct order. The consequences this time would be brought to bear on her; he would not be the only one who had to fix this situation.
 
Entering Zaraki's house, Toshiro quickly saw that the situation was worse than he thought. He was speaking as he opened the door and used that time to observe them, to see if the rumours were true. Matsumoto looked more satisfied than he had ever seen her, happier but also very untidy and her uniform did not seem to fit. Zaraki's hair was loose and he wasn't wearing his eye patch and he looked almost happy. That was chilling. They weren't touching and though they both denied any emotional entanglement, it was obvious to him that this was more than a purely sexual relationship. Why would Zaraki demand she be moved to his Division if she was only his sexual partner? Why was Matsumoto staring at Zaraki like that? If he didn't do something quickly, he might lose his Lieutenant, permanently, and though she irritated him beyond all reason, he liked and trusted her. She had proved her loyalty so often and they were friends. Making a quick decision, he ordered his Lieutenant to accompany him back to his office.
 
Without warning his temper rose. He'd told her, he'd warned her and again she had ignored him and become involved with that Captain. Walking back to his office his mind flooded with outraged thoughts. This was an ill advised liaison and he would try to give them time to come to their senses. He reprimanded her; insulted her in the way most calculated to shock her, by accusing her of wishing to sleep with all the Captains and then informed her that she was the final member of the party set to leave for the human world. He reasoned that if he removed Matsumoto now, this affair might not last the separation. As usual she seemed unaffected by the lecture, shocked at her inclusion in the mission and quickly left to be with her new lover for this last night.
 
Disgruntled, but not surprised, he completed the work he needed to do and when he was returning home he decided to visit Momo one more time, hoping she would at least be conscious so he could say good bye. Entering the room where she lay, he quickly walked to the bed and looked down at her sleeping face. His feelings had changed. He still loved this fragile girl, injured by the man she adored, who had ultimately tried to destroy her, but the love was that of compassion and friendship, nothing more. Quietly he stood there; the changes wrought in the last few weeks had made him reassess much in his life. Hearing the sound of someone entering the room silently he looked up to see Soi, staring at him in astonishment.
 
“Captain Hitsugaya. This is unexpected. May I speak to you outside, at once?” The words may have been phrased as a request, but it was evident that it was a command.
 
Speculating on what she might want, he followed her out of the room. As soon as he emerged from the doorway, Soi seized him by the coat and pulled him toward a door which she unlocked and dragged him inside and then locked the door behind them. The few seconds this required gave him time to observe where she had taken him; it was a linen room, where sheets and towels were kept. Soi quickly grabbed some off the shelf and threw them to the floor while he stood there. Grabbing his coat again, she tugged him to the makeshift mattress she had made and encouraged him to lie down in the cramped space. He opened his mouth to speak but she shook her head at him, sternly as she removed her hakama and became intent on removing his. He looked at her, her lower body naked while her upper half remained clothed and realised it was one of the most sexually charged sights he had seen. His cock, rousing when he saw her, was now rigid and pulsed with desire. He was nude from the waist down and she lay on her back, her hand straying to his cock, pulling it, using it to make him position himself above her. Not needing any further encouragement he quickly mounted her and pushed his erect cock inside her welcoming warmth.
 
“She touched me,” he thought. “I thought she'd never do that.'
 
“Soi,” he began, but she shook her head again, and pulled his mouth down to hers, whether because she wanted to kiss him, or to keep him quiet, he wasn't sure but her talented tongue began it's exploration of his mouth as she bucked strongly underneath him.
 
Instead of slow, this time their joining started fast and urgent, each of them encouraging the other frantic action, aware they were in a public place and would only have this chance for a short time. This proved to be only too true when they heard voices outside the door. Exchanging shocked looks, they stopped moving and listened, wondering if they would be discovered.
 
“Isane, as Assistant Captain Shuuhei is here to help me, could you please attend out patients. I think we will be busy in here for some time. If I need your help I will let you know.” They heard footsteps leaving and then Captain Unohana spoke again. “Thank you for your help, Assistant Captain Shuuhei. I need to take some linen for mending and everyone seems to be busy. That's strange, the door is locked, but I'm sure I had a key in the lock.”
 
“Darn it Retsu, you don't have to pretend, I've never heard a more transparent excuse. No one else is here. Come on, kiss me.”
 
“I know it's night time and there aren't many visitors normally, but we are still in the hallway. Some one might walk past. I thought if I gave the excuse of sorting linen, which everyone hates, we might have some privacy. If you recall last time you visited me in my office, Iemura kept knocking on the door. It really made it...” her voice was cut off suddenly and the door seemed to shift a little on its hinges as two bodies were pressed against it.
 
“What? Captain Unohana and Assistant Captain Shuuhei? I can't believe it.” Toshiro looked at Soi, who was looking rather amused at the overheard conversation.
 
“I left my keys in my office,” Captain Unohana sounded a mite breathless. “Come with me, we'll get them and then…”
 
“This is stupid. I want you to meet me at 9th Division headquarters in 10 minutes. I've told everyone I'm off duty for the rest of the night, so no one will be there. If you refuse, then that's it. No more secret affair, no more trysts in your office. I want you for the night, not just a quick fuck when you can fit me in. You know you want me. Your nipples are erect, I can feel them against my palm and I bet you're damp and itching between your legs.”
 
There was silence on the other side of the door. Soi pulled Toshiro's hands to her breasts and he noticed that her nipples were also erect and she was wet around him. He hoped that Captain Unohana would accede to Shuuhei's demands, because trying to stop his urge to thrust repeatedly into Soi meant that he would have to either withdraw or give in.
 
“10 minutes. I'll be there but you must keep your side of the bargain and make certain that no one is there,” Captain Unohana's voice was unsteady.
 
The sound of retreating footsteps was like a signal and Toshiro began to fuck Soi with firm hard and fast thrusts. She went wild, clawing his back, pushing against him, wrapping her legs around him as she urged him on, with tense little whispers. By now Toshiro wouldn't have been able to stop if the door did open. He was so close and Soi was beginning to tighten around him. As she came, she muffled her moans against his neck. A few more pushes and he felt his sperm empty into her as he fought the urge to yell.
 
This time he withdrew and lay on his back without looking at her. His eyes were having difficulty focusing and that was when they were closed, whether they would work when he opened them, he wasn't sure.
 
Soi got to her feet and rearranged her clothes. “Thanks. See you when you get back,” she said and left without any further comment or kiss.
 
“I am just a sex toy,” Toshiro thought with a tinge of melancholy. “I wonder if she even likes me.”

If you want more details about the conversation between Toshiro and Zaraki and Toshiro and Matsumoto it's in Chapter 2 of Different Circumstances.
 
Please review. As to an update, maybe. One possibility for another chapter crosses my mind.
