Solelollipop: Ah, Suki. I imagine she's still on some random island, keeping the peace for the Fire Nation. Damn Zuko uses her expertise a lot. I'm still writing when I can, believe me. It just takes some time.

"Tumbling boulder: The Toph Files"

Chapter eleven "Other heat"

"Careful…..there…..yes…." Toph murmured. She was between Changying's thighs, hips moving at a slow pace. She'd already come once but the woman was insatiable. She had no idea why. "Damn….are you going into heat or something?"

Changying stretched her arms above her head, her breasts bared from her sheer top bobbing with the effort. "Could be, Chief…. I can't get enough of you."

"Flatterer." Sometimes Toph got that hard look that said she saw through her. But then she got lost in the sex and looked more at ease. "Damn…."

Changying's thighs widened, and she ran a foot down the back of Toph's thigh. "Hmm, go on…."

"What about you?" Toph reached between them and stroked her clit with two fingers. "You ready to come?"

Changying blushed, groaning. It was apparent the alpha knew what she was doing, and her body reacted. Couldn't fake that. At least if she was going to be seduced, she may as well enjoy the efforts. Especially when Toph shifted back on her knees, leaving her thrusts long and languid as she teased her clit out of its hood with clever fingers. She could almost want to keep doing this forever. But Changying knew that wasn't going to be an option once her seed caught hold.

"Yeeeessss…"

Her unfiltered response seemed to urge Toph on and the police chief pushed her heels up onto her broad shoulders and took her with short hard thrusts. Changying knew they'd finish quickly but she could at least start the crux of her plan. She wafted her chi in unsubtle arousing waves and Toph grunted, the starts of a knot slamming against her on each thrust in.

"Fuck…" Toph looked down toward her with sightless milky eyes. "You ARE going into heat."

"Then knot me, Chief," she said coyly. Toph bit her lower lip and kept her thrusts short, her knot nowhere near to breaching her walls. Changying may not have been a bender, but even she had learned a few chi tricks from Hama. She coaxed her legs from Toph's shoulders, round her waist, and squeezed while stroking her chi with waves of sex and arousal. It was rather mean considering they were already in the middle of it and Toph rode her animalistic desires, thrusting harder and faster into her. When the top of her knot began to part her walls, Changying pressed her nails into the small of Toph's back, urging her on, her thighs wide as she hoped she was wet enough to take her.

And Toph's knot slid in with a loud shunk and the alpha's jaw hung open as she panted in ecstasy. Changying was equally incapacitated, loud mewls escaping her lips. Well, this assignment was certainly enjoyable. She rolled her hips beneath the alpha who then held her still and thrust harder, deeper, tied together. And they exploded, collapsing in on each other. Changying ran a hand idly through Toph's messy hair. The alpha was laying full on her, wasted and panting. It was almost a good sight. Almost.

The wetness she could feel coating her insides were a much more welcome feeling. Changying clenched around Toph's knot, coaxing out everything she had. Toph groaned, face pressed into her shoulder. "Stop that," she commanded, but her hips still moved, thrusting every few moments. It felt good so Toph allowed it, but panic began to set in. She didn't even know Changying that well and she wanted to come over while entering her heat? Was she nuts?

Toph's confused feelings escalated when a sharp wail came from the next room. Lin had been put down in her cradle and now she couldn't get up to get her. She tried to get up and out but a few squeals of pain and smacks from Changying kept her tied. She rolled on her back, the woman tied to her laying across her. She did not like the feeling of being attached by the dick to this woman she barely knew.

"Wait a moment, Lin!" Toph called trying to pump out pheromones of comfort to her child. But the woman on top of her had shrugged off her negligee top, and her nipples scraped across Toph's torso. Toph spread her knees and let the woman settle in. May as well get comfortable. She huffed with frustration as she heard the baby sniffling in confusion, wondering where she was. "Dammit….she needs me…"

"Don't worry….almost soft enough," Changying said in a soothing tone. She brushed Toph's bangs out of her eyes and leaned to kiss her. Toph accepted the kiss, gentler as it was, and relaxed. And slowly, the vivacious woman was pulling off of her, dismounting with a groan that sounded almost pained. Toph hopped off the bed and threw a robe on, heading for the bedroom door.

"You okay?" She called back as she ran to collect Lin. Her baby was sitting up, and her hiccupping cries filled her with guilt. She wailed and Toph hurried to change her and grab a bottle, hoping she didn't smell too much like sex. Soon Lin was in the crook of one arm, sucking mightily at her breakfast. Toph carried her into her bedroom from where the flexing chi signature told her Changying was still in her bed. "Changying?"

The woman giggled and the sheets rustled. "I'm okay. Sorry we got tied up like that. Morning, little one."

Her words were amicable toward her offspring but sometimes Toph felt the hairs rise up on her arms around her erstwhile girl 's attempts. She sat on the edge of the bed, listening to Lin suck on the bottle's nipple. "There you go, little earthbender," she murmured to her child. The pulse of warmth from the child filled her with purpose, mess aside or not. Toph blew her bangs out of her face as she rocked Lin slowly. As she listened to Lin suck and make small noises of comfort, Toph couldn't help worrying about her. Suki's child, she was all she had of her, and here was a strange new girl in her bed. What would Suki think?

Changying ran a hand over the back of her robe in an affectionate pass and Toph felt her lips quirk in a smile. Well, she could still attract others. Suki had missed out. The boastful thought didn't make her bruised heart feel any better but whatever.

"Shall I come back for dinner later?" Changying asked. Toph nodded.

"If you want." She expected that. Changying seemed to be entering her heat. That she was thinking of leaving the apartment was slightly alarming to her alpha sensibilities. Her loins ached thinking of the seed she had just spilled into her. At her primal core she didn't want anyone else to sample what she'd just had. "Or you could stay here."

"And you could stay all day." Changying sounded positively giddy. Toph's alpha pride was soothed. "Can Sen take little Lin for the day?"

Toph felt brief panic at that. She had never been out of the same room as her child longer than a work shift. Sen had been hired to help during these trying early months. But she hadn't expected the current situation. Sen would take Lin, if she asked, but it would be too awkward and cruel of her to have her watch the baby in the same apartment while she serviced an omega's heat. She'd have to take Lin to her own place. Luckily, Sen was of a good family, and Toph knew her mother, had met her several times, and knew she'd help with the baby's care at her house.

"I guess….I'll call her," she said. Toph burped Lin and handed her to Changying. The hesitance she had before accepting the baby put a spike of warning in Toph. But she had to go downstairs to make the phone call. "Just for a minute, here."

"Okay…."

Toph tried not to get annoyed as she put on some clothes and made her way downstairs to locate the building manager to dial Sen's house number for her. She waited for the clicks and after talking to a house servant, was put on with her nanny.

"Hey, Sen. Would you be willing to watch Lin for longer than usual today?" Well no time to go beating around the bush.

"Sure, Miss Beifong. I'll be right over as soon as…."

"Actually, I was wondering if you could take Lin to your family home for the day."

A pause. "Why? Is something wrong with your home?"

Toph scratched the back of her neck with one hand. "Well, I may actually have a personal issue…..I'll pay extra if you need."

"No, that's okay Miss Beifong. And my mom will help with Lin too if she's here," Sen said sweetly and Toph could have kissed the kid.

"Great. Come to get Lin in alittle over an hour?" Toph asked. Sen agreed and they hung up.

Toph tried not to run up the stairs. She had them identified by count, but she did want to get back upstairs and take command of her child back. Changying was many things, but a good caretaker didn't seem to be one of them.

The baby's sniffles met her ears and Toph rumbled in response, taking her and calming her with her chi. Lin quieted immediately.

"So, is it taken care of?" Changying's hand was on her thigh, caressing. Toph nodded, focusing on Lin's burps and sighs.

"It is. Sen will be here soon, sit tight."

But Toph couldn't find it in herself to follow her own advice. Changying's smell was making her begin to sweat at the temples. She took a shallow breath. She focused on Lin's small babbles and tugs on her tunic collar to not fall to desire right that moment.

Later that night, Toph woke from a hard nap, surveying the darkened shadows overlaid over the shapeless room, turning toward the chi signature in her bed. The chi mass laid languidly, coiled in one knotted rope as Changying slept. She smoothed a hand over the bare form next to her and Changying groaned in her sleep. She murmured a name that Toph couldn't quite hear but knew it wasn't her own.

And that was fine. Toph was thinking of Suki. She frowned. She didn't really want to, but she couldn't help comparing them. She felt more at ease when Changying was asleep instead of awake. Even now, sweat drying on her skin and smelling the girl's delicious scent, Toph was glad the sharp-tongued girl wasn't conscious. She needed to think, and her body kept getting the best of her.

Oh well, it wasn't like they were mated or anything. Thoughts of Suki spread through Toph's mind and she grunted, turning to swing her legs over the side of the bed. She needed a drink of water and a piss, and maybe not in that order.

"Toph?" Changying murmured as she began to wake. Toph shut the washroom door, cursing in her mind when she almost went to the other bedroom toward Lin's cradle. She was safe at Sen's mothers house. Safe, right? She tried not to panic or shiver.

"In a minute!" she called. Needs taken care of, she opened the door, naked as she dried her hands. Changying was waiting for her turn and after pressing into her side, naked flesh warm and soft, Toph's mind went to more interesting avenues. She lay back on the bed, tangled sheets at the foot, waiting.

Changying came back in and curled up on her torso, hand teasing her shift, and pressing kisses around her breasts. Toph gave a smug smile as she stiffened in the clever woman's hand.

"You still smell good," she murmured and Changying giggled against her. She leaned up to kiss her and Toph grabbed her wrist, flipping the woman onto her back. If there was a heat in her lap, she was going to enjoy herself.

Two days later, Toph woke, mentally preparing to call Sen and bring her child home, and to get back to the station. She'd have to talk to Changying about what she intended to do and if she needed a kajihana tea. The local clinics carried it for those in need and Toph had knotted her more than five times. How many had it been? An alpha couldn't be expected to be the model of resistance when an omega was in heat. She'd have to have a talk with her. But as she woke, she couldn't sense anyone else in her bedroom. Toph's hand passed through the empty sheets and she sprang to her feet. Her shift had retracted after their last time, so she moved quickly through her apartment.

"Changying?!" Her alpha sensibilities wanted to ensure the woman she'd put her seed into was taken care of. Whether she needed a tea, or…..heck if she knew, she had to check up on her. Did she leave already? The silence in the apartment was foreboding. Toph missed the shrill cries of her baby even. Lin, Sen was due to bring her back this morning, any moment now? She hurried around the apartment, reaching for any chi signatures. Nothing. Only cold inanimate objects met her outstretched hands as she had to rely on touch when feeling with her chi brought not one result of anyone else there. Toph was crawling on the floor in her living room when her knee crinkled on a piece of paper. A note? She smoothed it out and cursed herself. She'd have to get her manager or someone to read it for her.

Toph tried to calm down but she felt like choking. First things first, get dressed. She had to force herself into a quick shower. IF she was going to be around people, she didn't want the scent of sex to put them off. Or her child. A thought of Suki made Toph felt guilty then she pulled on her police uniform. She needn't feel guilty. It was done.

After settling things with Sen, she'd go to the station and get some help to locate Changying. She longed to feel Lin in her arms again and she hated she'd have to leave her again for an hour or two more.

After what felt like an eternity, there was a knock at her door and Toph flung it open in a hurry. She listened to Sen chirp a greeting and gladly took the bundle of wriggly happy chi from her. She sighed, feeling Lin press into her torso, curling trustingly into her sire's energy. Small babbles rose to her ears and Toph allowed a smile, ducking her chin to the top of Lin's head, inhaling her scent from her tuft of hair.

"Baby," she said, a moment of happiness piercing the maddening confusion in her mind. Lin squealed aloud and Toph rocked her. "Come in, Sen."

"Did you have…a good two days?" Sen inquired. Toph could almost sense her looking about for the woman that had commanded her attention. Toph blushed hotly imagining the mess they'd left the place.

"Fine, fine," she said blithely. "I'm so sorry to leave Lin again, but I need to check out things at the station. I won't be long today."

"Of course," Sen agreed. She started straightening up, from the sounds of it. Toph gave Lin another kiss on the brow and handed her over reluctantly. Then she felt the crinkle of paper in her pocket and sheepishly handed it to her nanny, head lowered.

"Could you?..."

"Sure thing," Sen said brightly. She cleared her throat. "Went out to get some things. 'Til next time, Chief."

Toph felt sheer panic rip through her. Was Changying's heat even over? Why did she leave and without waking her? What did all this mean? A headache was threatening to debilitate her and Toph blinked, willing the sharper shadows away. "Uh…"

Sen's words were very understanding even though pity lined her tone. Darn, even the kid was taking pity on her situation. "Well, she'll….she'll get back with you. I'm sure of it."

"Was there…." Mentally, Toph berated herself for the first time in years that she couldn't see. "Was there anything else on there?"

"No, Miss Beifong."

"Okay…" Toph turned to leave, footsteps light and feeling rather lightheaded.

She tried not to run all the way to the station, but she did hurry. People hopped out of her way and little kicks of the earth they stood on helped clear the way. Once inside, her officers rushed her, all asking or reporting at once. Toph tried not to growl, feeling a bead of sweat roll down her spine beneath her uniform.

"One at a time!" she called. After running a hand through her bangs, she took the first offered verbal report and a few more. "Enough of this, get back to work, I need to locate someone."

"Who, boss?"

"Girl named Changying."

"Surname?"

Toph felt even more spreading panic. "I….don't know it."

"Well… we'll help make inquiries."

"You do that. I'm going to walk the beat outside," Toph said. She adjusted her overcoat and went on her way, sliding her metal retractors up the sheaths on her forearms. This girl had caused her enough worry; she was really going to make her track her down, wasn't she?

"Dammit…." Toph muttered. Her body's desires had made her a slave to answer to them. And she had a feeling this had caused a mess of some kind. In her heart of hearts, Toph really wanted Changying to be okay. If she truly were an okay person and had wanted to spend time with her, she hoped she could find her. And sort out what was happening.

She sighed and continued on. Some of the shop owners had gang connections and she could bend a few ears hopefully.

"Blast it, girl! You're still in heat!" Yakone snapped. He covered his nose with the sleeve of his suit jacket, frowning at her over the top of his hand. And he stepped a few generous feet back, but Changying saw his bodily reactions as his trousers tented outward.

"It's ending, I can assure you of that!" Changying snapped. She tossed her overcoat to the side. One of Hama's benders folded it neatly for her. "Is it too early to assess a conception?"

"You done riding that police chief?" one of the women scoffed. Changying flounced by and kicked her heels off.

"For the time, yes," she boasted. "She couldn't keep from climbing all over me."

"I'll believe the end results when I see it," one of the men sniffed. He kept back as well, even though he was a beta. One of the older women was consulting a horoscope scroll and nodding at a calendar.

"Well we won't be able to assess an additional chi signature for a few weeks at least. How many times did you knot?"

"Enough times," Changying gave a languid grin.

"Well, at least we can force the police chief to step down. And put Ching in the position," one of the blood benders said. Changying nodded.

"And you all thought I couldn't do it. Once I get pregnant, we can force Beifong to do whatever we want. Dance to your will, if you want," Changying placed a hand over her flat stomach. "I may be pregnant already…."

"Well then sip this, little mother," one of the women scoffed, handing her another tea. Changying's nose wrinkled at the smell.

"Another fertility tea? Really?"

"We want what's there to take root, don't we? Drink it," the older woman chastised her. The younger woman shrugged and took a careful sip. She grimaced.

"I just want to put my feet up and relax. Beifong was by far an exhausting study."

"Oh, admit it, you love the pleasure missions."

Changying's lips spread into a predatory smile. "Yes, I do…."

"Drink up already."

Changying sipped her tea.

Katara was definitely surprised there was a knock at the door of their new home on the newly furnished Air Temple Island. The White Lotus must have admitted the visitor. She anticipated a city council member, or someone else with an inquiry for the Avatar. Really, couldn't they give them their evening hours just for their family? Katara cradled Kya in the crook of one arm as she unlatched the front door. The newborn was in a sling around her neck and she cradled her arm under the curve of her tiny body.

"Toph!" Katara exclaimed. Her old friend was there, police over coat unbuttoned, Lin wrapped in her own sling around her neck.

"Hi, Katara. Can I come in and have dinner or something?" Toph asked. Katara got there was something else unspoken.

"Sure, come on in! Kya's going down soon anyway…."

"Thanks," Toph said gratefully. Lin babbled in her arm as she walked in, easily following her friend's chi signature futher into the house.

"Toph, hey! What's up? You want lettuce wraps for dinner too?" Aang called nearby. A giggle from high up indicated he was carrying his young son up on his shoulders. Toph gave a wry grin to no one.

"Only if it has loads of meat in it! Got any to spare here?"

"Eh, for you and Katara," Aang said. "Come on in."

"Toff!" Bumi crowed as Aang juggled him down to his feet. Toph tensed in surprise when two small arms suddenly flung around her knees.

"Hey, watch it, kid."

"Toff, see Lin?" Bumi asked. Toph carried Lin into the dining room.

"Sure, go ahead and take a look." Toph knelt at the dining table and Aang's servants began setting their dinner. Aang expressed thanks at his plate of tofu and vegetables and Toph could smell when the meat was brought in for everyone else. Bumi pushed away an offering of tofu and giggle when meat was offered to him.

"So, what brings you here? Not that we're complaining," Katara said. She'd put Kya down in her cradle and was free to help watch over Bumi's chopstick technique.

Toph sighed. "I look that bad huh?"

"I wouldn't say that," Aang said. Katara cleared her throat.

"Is it….. Lin's mother?" Katara asked gently. The way she and Aang shifted told Toph they had discussed Lin's parentage many times in private.

"No. Yes. Sort of."

"No matter who had Lin, can you reconcile with her?" Aang asked gently. Toph only this level of softness from her old friend. Anyone else would have gotten a fist to the face.

"I don't' know. It's very, very complicated," Toph mumbled. Lin snored against the front of her uniform shirt. She rocked her in one arm. "But she left me and…."

Toph could tell her friends were sharing a silent look. She wished she could gauge their expressions first-hand.

"So, what's got you down about her? Did she contact you?" Katara guessed.

Toph shook her head. "No. Even if I wanted her to…" she cleared her throat. "I met a new girl. At your stupid council dinner, Aang. And we got pretty friendly."

Aang nodded to himself. "I see. Is she a good match?"

"I don't know," Toph admitted miserably. She put her chopsticks down on the plate. "We uhm, well she shared her heat….with me. And then she disappeared. I can't find her anywhere."

"Do you love her?" Aang asked gently. Toph sighed.

"No. I don't know her that well."

"This is troubling," Katara agreed. "Do you think something happened to her?"

"It's possible. But no one has any information on her."

"What's her name?" Aang asked.

"Changying."

"And her?..."

"I don't know her surname, if she has one," Toph admitted. Saying it out loud made her feel even more stupid if that was possible.

"We can ask around for you," Katara added. "The White Lotus have a lot of feelers in the city and elsewhere. Don't worry, Toph, we'll find her."

"Thanks, guys." Toph wondered if finding her would be worth it. But she had to know what had happened to her. Lin woke and gave a soft cry against her tunic. Bumi leaned closer, giggling.

A month passed. Toph took it in stride as she could. She went to work, Sen watched Lin, and she came home to her happy child. Toph tried to be happy with that, truly, but she still looked for Changying every day when she was out. She put in questions to shop owners, gang leaders, and asked the ruffian kids what they'd heard or seen. Either they didn't know or they were covering up her tracks.

It was like she'd made up that heat and the woman herself, for she seemed to have vanished into thin air. It was like to drive her mad.

One evening, Toph came home and said goodbye to Sen, paying her and taking control of Lin. She was rolling over to her tummy now and trying to crawl. It startled Toph to keep track of her wriggling chi signature so she wouldn't have her underfoot accidentally. But she took pride that her child was getting bigger.

So when she got a knock on her door almost at dinnertime, Toph was confused to say the least. IT could be Sokka, it could be one of her friends. But she usually knew ahead of time. And she dind't like the swirling masses of chi she could feel out in the hallway. More than one. Who was this?

"Who is it?" she called through the door.

"Changying." The familiar lilting voice called. Toph admitted she went to open the door alittle too quickly hearing that. Lin plopped on her belly on her blanket in the living room, babbling. She reached a hand out but her wrist was clutched away from her goal by Changying's hand.

"What in the…" Toph said. Her wrist wouldn't move either, locked by some kind of force that wasn't a form of bending she knew. "Changying?!"

"Good to see you, Toph," she purred. But the group of men and women in long coats and hats behind her gave Toph pause. She angled Lin to the side.

"What's all this about?" she asked.

"I just want to talk. Can we come in?" Changying purred. The hairs on the back of her neck rose and Toph froze.

"I don't think I have a choice."
