I don't own The Loud House.

Well guys I have finally returned to writing once more. After my move I had fallen into a bit of a slump when it came to writing. I didn't feel motivated to write so I took a vacation of sorts. A much needed vacation I might add. But now I'm tanned and rested and I'm ready to bring you quality content at the fabulous low, low price of free 99. Lol.

I'm currently working on the chapters for my other ongoing stories that I've been neglecting during my vacation. I will be releasing them in order starting with this one. Next up will be Too Many Dates, then Digi-Loud Adventure, then Terms of A Dress, and finally What She didn't know. I was gonna release the next chapter of Terms of A Dress but as I was reading again because I was also working on the sequel to it, I noticed that I made an error in the last two chapters. So I'm editing chapter 9 and 10 and reworking them so that the sequel story doesn't seem out of place.

And to those of you who have been messaging me and asking if I'm still alive, I appreciate your concern and I have responded to most of you. Except for Dough. Fuck Dough. Nah, I'm just kidding.

Keep in mind that I am still pretty busy so the updates will probably still be coming in every couple of weeks after the latest chapter. So when I post the next chapter of Too Many Dates, which is ch 17, ch 18 won't come until 2 weeks after that. Sorry if it's confusing but if you have any questions just leave them in the reviews and I'll answer them as soon as I can.

Lust For A Loud

Chapter 15: Experimenting

Lori was texting on her phone in the living room while her mother sat with Lily on her lap, sitting on the armchair and facing the TV. It was just a boring Sunday and there was nothing interesting on the television so Lori ignored it. She was currently texting Carol, teasing her about her new crush. Carol had yet to tell her who it was but she was close to making her crack.

Just then her brother walked into the house from outside and he looked weary, probably due to the run that Lynn made him take that morning.

"Hey Mom...hey Lily..." Lincoln greeted, sounding as tired as he looked.

"Hi Sweetie, how did your morning jog go?" Rita asked her son while Lily giggled as she reached for her brother.

"It went as well as you'd expect when you have Lynn leading the charge." Lincoln said with a grimace. "I managed to ditch her about five miles into the run and now I don't know where she is. Hopefully she's halfway to Mexico so that she can leave me alone for once."

Just then Rita caught a whiff of her son and she made a face. "I think you might want to go get cleaned up, son, you're all sweaty."

"Yea...I was planning on taking a shower right now." Lincoln nodded. He was about to turn around when he felt a tug at his shirt. Looking down, he saw that Lily had reached out to him.
"I have an idea, why don't you take a bath and you can take Lily with you?" Rita suggested. "That way you can give her a bath as well since she needs one anyways."

Lori perked up at this. She watched as her mom tried to hand Lily off to her little brother.

"Isn't she a little young to be using the big tub?" Lincoln asked.

But Rita shook her head. "You were barely over a year old when you started taking baths with me."

Lori couldn't help but smirk. "That explains a lot, huh, you little perv?" She teased him.

"I don't remember taking baths with mom and I plan to keep it that way. Come here, Lily." Lincoln said as he took his baby sister from his mom. Lily seemed ecstatic as Lincoln picked her up. "Do you want to take a bath with your big brother, Lily? Do you?"

"Wincon!" She cried out happily, kicking her feet.

"I'll take that as a yes." Lincoln said with a smile. He held her closer to his chest and he started to make his way towards the stairs.

Lori turned to her mother. "Mom, he's 11, don't you think it's a bit weird for him to take a bath with his sisters?"

"Lori, Lily needs help taking a bath since she can't do it herself yet. Lincoln's going to take one anyways so this is the best way to do it." Rita said, waving her daughter's concerns off. "Besides, your brother is very responsible."

"But he's still a bo- oh nevermind, I literally don't care anymore if you're," Lori was saying when she heard Lily call her name from across the room. "Sure?"

Lincoln had stopped and turned around in order to address their mother. "Mom, where are Lily's diapers? She's gonna need a new one after she's clean."

"They're in the same drawer as always, dear." Rita said as she turned around in order to grab him a new one.

While Lincoln and Rita were distracted, Lily had called Lori's name to get her attention. And while her older sister was watching her, Lily held both hands in front of her mouth like she was holding onto something big and she mimed like she was shoving in and out of her mouth, using her tongue to push against her cheek as she shoved the imaginary object in.

Lori's phone fell to the floor with a dull thud as she stared wide eyed at what Lily had done. She knew exactly what the toddler was doing and the sheer audacity of that child shocked her into freezing. And she remained stunned until Lincoln carried Lily up the stairs and out of sight.

"Mom!" Lori said as soon as she snapped out of it. "Did you see that!?"

"See what, dear?" Rita asked her daughter.

"What Lily just did!" Lori said, pointing upstairs.

"I don't have eyes in the back of my head, dear, so no, I didn't see what Lily did. Was it cute?" Rita asked.

"No, it wasn't cute!" Lori said as she stood up. "I'm gonna go with them to the bathroom!"

"You're gonna go take a bath with your 11 year old little brother?" Rita asked in a deadpan voice. "I thought I raised you better than that."

But Lori wasn't listening anymore, she rushed up the stairs and burst into the bathroom. "Lincoln stop!"

Lori couldn't believe her eyes, Lincoln was sitting on the toilet with his legs parted slightly. He had his eyes closed and he had his hand on top of a tuft of blonde hair.

"That's right, Lily, just like that..." She heard him say.

And standing in the middle of his legs was none other than their youngest sister, Lily, gripping his hardened member as best she could with her tiny hands as she took his tip in her mouth, using her tongue to lick it like a lollipop.

"Your milk tastes so good, big brother..." Lily said in a voice that sounded much older than hers and it was strangely anime sounding. "It tastes better than mommy's."

Lori was frozen in place, unable to move or shout. All she could do was watch as they continued this vile act.

"Give it to me, big brother, give me all of your milk!" Lily cried as she slid her hands back and forth along his shaft, effectively jerking him off.

And just as he was about to cum, Lori watched as Lily opened wide in order to accept his entire head into her mouth before she began to suck again with increased vigor.

XXXXXXXXXXXXXXXXXXXXXXXXXXXX

Lori woke up with a start and she sat up suddenly, breathing hard. The memories of her previous dream were still fresh in her mind. Glancing around, she saw that she was lying in her bed with her brother lying on her right and Leni next to him. Ever since they started loving their brother, someone was always with Lincoln. This week was hers and Leni's week to cuddle with Lincoln at night.

Sighing, Lori tried to process what she had seen. It felt like a memory but it was definitely a dream because Lily couldn't talk yet and she definitely didn't sound like one of Lincoln's anime waifus, as he called them. The strange part was that Lori was disgusted by that dream, no, she actually found it a little arousing.

"God what is wrong with me?" Lori muttered to herself.

While the six oldest Loud girls were regularly having sex with Lincoln, Lori had forbidden the four youngest from having sex with him until they were older. Technically, Lucy was supposed to wait until she was 12 but much to their surprise, she proved to them that she was ready by showing them that she could get wet. Lisa theorized that just like Lincoln, all of the loud girls also had hyper active sex drives and that they all matured a lot sooner than normal girls. Lori could still remember touching herself for the first time when she was nine.

And speaking of the younger Louds, Lori had to remind herself to keep an eye on Lola and Lana. They had been trying harder and harder to seduce their big brother and Lori was afraid that Lincoln would cave sooner rather than later. After all, he could hardly deny them anything since he was such a big softy. Chuckling, she could recall a time when he had to be the one to punish them and he felt terrible about grounding them for 1 hour in their room. His compassion was one of the many things that she loved about him.

With a sigh, Lori carefully got up from her bed and sat down on Leni's. She wasn't sure why she had that dream, she definitely wasn't going to have Lily give Lincoln a blow job. But a part of her wondered if perhaps she wanted to let the younger Louds do it a little earlier than she originally thought. She would have to consult with Lisa since she was literally a genius and would know a lot better than her. Thinking about it, she would also have to ask Lincoln about how he felt about that. When it came for Lucy, Lincoln had been at ease and almost eager to do it with her. He loved Lucy, seeing her as special among their family because of their unique bond. Even as close as they all were, Lori had to admit that no one knew Lucy as well as Lincoln did. Perhaps it was because he was her big brother and he felt a need to be overprotective of her. Whatever the reason, she knew that they had made the right choice when she saw how gentle Lincoln was with her.

"Man...now I'm getting horny..." She muttered to herself. Looking over at her bed with Leni was currently using Lincoln as a teddy bear, she sighed when she realized that she should've had sex with him before bed. But Lisa had told them that Lincoln couldn't have sex that night. She didn't explain why, just that it was important.

"Maybe I just need some coffee..." Lori got up and left her room, making her way down towards the kitchen.

But as she was about to pass into the kitchen, she noticed that the basement light was on. Curious, she opened the door to see that the light was indeed on and that there was a familiar noise coming from down below. A very familiar noise. With a frown, she made her way downstairs after closing the door behind her and when she reached the bottom she couldn't help but gasp.

In the corner of the basement where they had a hidden bed tucked away Lori could see three of her sisters. The first that she noticed was Luan who was lying face down on the bed while facing the stairs. She had a ball gag in her mouth and her arms were bound behind her back with her knees bound to as well so that her ass was propped in the air. Her hair was loose and it had fallen over her face partially covering it but Lori could see the look of pure ecstasy on it. Then there was Luna, who was completely naked, and she was wearing a strap on while she penetrated Luan's butthole. And she was giving Luan's cheeks hearty slaps causing the girl to moan out in pleasure with each hit.

And the third sister Lori recognized had the right face and even hairstyle but she appeared much older than she should be. Lisa was currently sitting completely naken on the bed as she watched the two sisters have sex while she touched herself. But what was stranger than even that was that Lisa looked like she was 16, not 4.

"What the hell is going on here?" Lori demanded as she finally found her voice.

Startled, Luna pulled out of Luan and spun around. And much to Lori's surprise, Luna's 'strap-on' shot out several white globs that felt familiarly hot against her skin. Dumbfounded, she stared down at Luna's crotch and she realized that the strap-on she thought Luna was wearing was actually a fully erect penis. A very familiar fully erect penis.

"Dude, Lori, what are you doing here? Shouldn't you be sleepin' bruh?" Luna asked as she looked at her older sister.

"That should be my question! Why do you have a dick? Wait, fuck that, why do you have Lincoln's dick!?" Lori demanded as she wiped the semen from her face.

But Luna just grinned. "I knew you'd be able to recognize the little dude's junk. Luan owes me 10 bucks!"

"That's literally not the point here!" Lori shouted.

"Easy, easy." Luna said as she held her hands up in a placating manner. "We were just testing out some of Lisa's new pills."

"Pills?" Lori turned to her now aged up sister and glared. "What the hell have you done?"

"Sister, I do apologize for not telling you sooner." Lisa said as she continued to finger herself. She was panting and moaning, signifying that she was close. "B-But...I didn't not wish to...ah...disturb your time with...ah...with our brother."

"Will you stop! I need answers here!" Lori said, placing her hands on her hips.

"One moment!" Lisa increased her ministrations and within moments she cried out Lincoln's name as she came, squirting her climax all over Luan's face. Once she was done, she took several calming breaths before she cleared her throat in order to address her eldest sister. "As I was saying, I meant to tell you sooner but I did not wish to rob you of your time with our brother. Luan and Luna agreed to help me test out a couple of my most recent inventions and we should know soon if they are permanent or not."

"Wait, you don't even know if they're permanent or not?" Lori almost shrieked. She turned to look at Luna. "You might have that dick forever!"

Luna just grinned. "Pretty rad, huh?" She then began to stroke her member, shivering as her touch seemed to stimulate her in a manner that she had only just discovered. "When Lisa said that she could give us a replica of bro's dick, I knew I had to be the one to take it for a test drive." She then glanced over at Luan who was still out of it from her most recent orgasm. "And judging from the state that chuckles is in, I'd say that I rocked her fucking world!"

Lori stared at Luna for a moment before she pinched the bridge of her nose and sighed heavily. "Oh my fucking god..." She muttered. Turning towards Lisa, she decided to start with her. "Okay, what did you do to yourself? How come you're literally a teenager now?"

"Oh that's quite simple really." Lisa reached up and cupped her breasts which were a nice C-cup. "I took a pill of my own creation that was designed to temporarily age the user up by approximately ten years."

"You're FOURTEEN?!" Lori blurted out. Looking at her sister more closely, she could see that Lisa had hit the genetic jackpot just like Leni had. Lisa had curves in all of the right places and if Leni was any indication then Lisa's breasts were still developing.

"I know, bruh, I couldn't believe it either." Luna said as she eyed their sister enviously. But then she grinned as she continued to stroke her now hard member. "But luckily I got this amazing dick and let me tell you...if this is what Linc feels every time that he cums then he's fucking lucky! I kind of want to make this permanent now."

"Unfortunately I cannot make that permanent..." Lisa said. "Yet."

"Do...do you still have a...you know what?" Lori asked, unsure if she would somehow offend her sister by asking if she still had female genitalia.

But Luna just rolled her eyes. "Nah, bruh, I don't have a pussy anymore or at least for now." Luna reached down and gently pulled up her ballsack. "See? No girl parts, just dick and balls."

"Lisa...how?" Lori asked her genius sister. "And more importantly...WHY!?"

"I could bore you with the science behind my most recent creations but suffice to say that I've been working on them for a number of years. As for the why...simply because I could." Lisa answered her. She then grinned as she eyed Lori. "Now, eldest sister, would you like to assist us with my experiments?"

It was at this point that Lori realized her mistake. She had come downstairs in order to see what was going on and she had unknowingly walked into a trap. And while she would normally run out of there screaming, a part of her was curious. Gulping, she looked over at Luna's dick and she couldn't help but lick her lips.

"Y-You said that that's a replica of Lincy's dick, right?" Lori asked, subconsciously rubbed her thighs together.

"An exact replica." Lisa confirmed. "I spared no expense when it came to its creation. Though sadly, the semen created by the replica penis isn't Lincoln's. It's actually Luna's."

"Wait, so if Luna were to get me pregnant, it would actually be mine and her baby?" Lori asked, surprised.

"Affirmative. The pill only creates a replica of Lincoln's male genitalia, replacing and converting your female organs with his male ones. But the semen created contains your DNA, not his. After all, it's your body that's using the penis." Lisa explained.

"Huh...that actually makes sense." Lori admitted.

"But of course. I am a genius." Lisa said, sounding a bit smug.

"Enough of that, bruh, are we gonna fuck or what?" Luna asked, sounding a bit impatient. Lori could already see precum dribbling from the tip of her penis and she felt a sudden urge to lick it all up like she did with Lincoln.

"Only for science, okay? I'm literally only doing this because I'm curious to see if it really is the same as Lincy's dick." Lori said as she began to strip herself down to her birthday suit.

"Whatever you say, love, whatever you say." Luna grinned.

Lori knelt down in front of Luna after placing a pillow down on the floor of the basement. She had to admit, she was trembling with anticipation. After waking up horny, she really needed this. And while she was no stranger to girl on girl action, this was on an entirely different level. Reaching up, she grasped Luna's dick with both of her hands and she was surprised to see that it felt exactly like Lincoln's penis. This helped reassure her about what she was about to do since it was so familiar to her.

Cupping Luna's balls, she gently played with them just like she did with Linc's. And with her other hand she began to palm the tip and she would smear her precum down the shaft. Lori could hear Luna groan with pleasure, claiming that she had never felt that before and begging her to keep going. Feeling confident, Lori continued to tease Luna, now using her mouth to plant little kisses to the side of her shaft, giving it a lick here and there.

Meanwhile, Lisa had walked over to Luan's near comatose body and she began to untie her. Lisa had taken one of the penis pills while Lori had begun to undress and she could already feel the effects taking hold. The sensation was similar to having her privates heated up like a furnace with the added effect of a tingling sensation located in her crotch. She then felt something begin to grow and expand slightly where her vagina used to be and when she felt the sudden drop of her testicular sack, she knew that the transformation was complete.

"Now let's see just how effective my new penis is." Lisa said with a grin.

Luan regained enough of her senses just as she began to feel a familiar prodding at her entrance. She smiled as she looked up expecting to see Lincoln but instead she saw Lisa.

"You're not Lincoln..." Luan muttered as she glanced down at her now much older sister. "And how long was I out for? Luna's dick couldn't have been that good, could it?"

"Fear not, sister, you were not in a coma or anything of the sort. I merely took an aging pill that temporarily granted me the body that I would have at 14 years old." Lisa explained as she rubbed the tip of her dick at Luan's entrance. "I also took the same pill Luna did and have gained access to our brother's magnificent penis."

Luan glanced over at Luna and saw that Lori (when did she get there?) was currently giving Luna a blowjob that by the looks of it was making the Rocker Loud see god. And still being incredibly horny, Luan wrapped her legs around Lisa's waist as she reached up and cupped her sister's left breast.

"Puberty was so unfair to me..." She lamented as she gave the breast a light squeeze. "We're almost the same age now and you're much bigger than I am..."

"Do not worry, Sister, I will soon make that the least of your concerns." Lisa promised.

And as Luan began to feel Lisa penetrate her, she grinned as she said. "You got the hardware now so I expect you to drill me like Lincoln does."

Lisa moaned as she slowly inserted herself inside of Luan, the feeling of her sister's pussy wrapping itself around her member was intoxicating. She understood why her brother loved having sex so much, it was just as enjoyable for him as it was for them. But this was a unique experience for her as Lisa had never attempted to give herself a functioning penis before. And if she was being honest with herself, she might not want to go back to having a vagina if it meant giving up that glorious penis. But she knew that she would give it up because as much as she enjoyed penetrating Luan with Lincoln's dick, she much prefered having Lincoln penetrate her instead.

"Ooooh yea...just like that..." Luan moaned as Lisa began to move in and out of her. Her pace was slow and calculated, almost as if Lisa was making sure to experience each stage of having sex. She would slide in a little bit a time before pulling out and sliding back in. Normally Luan would have preferred to be fucked fast and hard but she was enjoying the thorough job that Lisa was doing.

Within moments Lisa's pace began to pick up and Luan pulled her closer with her legs, helping Lisa reach deeper inside of her. She knew that Lincoln was big enough to reach her womb and she wanted Lisa to do the same. There was just something so hot about being filled to the brim with your brother's dick. As Lisa continued to thrust inside of her, Luan moaned her name.

"Lisa...oh fuck...fuck me like that...ah...yes...right there!"

Lisa smirked as she heard her older sister's cries of pleasure. She was also experiencing a new and rather pleasurable sensation of having her penis be closed in on from all sides. It felt as though Luan's pussy was attempting to swallow her penis whole in an attempt to prevent her from ever leaving. The tightness of her sister's vaginal walls closing in her were stimulating her in ways that she hadn't thought possible. If this is what Lincoln felt everytime that he had coitus then Lisa knew that evolution had clearly favored males over females with how easy it was to get them off. She had only been thrusting into Luan for about 10 minutes and she already felt like she was nearing her limits. And if Luan kept moving her hips like that, Lisa wouldn't last another 10 seconds.

"I'm...ah...I'm cuming!" Luan cried out as she arched her back, gripping the bed sheets and curling her toes as she felt Lisa's dick plant itself deep within her.

The sensation of having a male orgasm had left Lisa speechless. All she managed to do was grunt as she buried herself within her sister's womb and released her seed. Her eyes nearly went cross eyed and for a moment her whole body tensed up as she felt a pull from deep within her balls as copious amounts of semen were suddenly shot out through her penis and into Luan's womb. The boiling liquid that she had only felt being poured in her felt very different as it shot out of her. A feeling of euphoria washed over her whole body that seemed to spread from her penis. And after a moment of pure bliss, Lisa exhaled and she collapsed on top of her sister, panting as a sudden wave of fatigue hit her.

"Holy...shit..." She muttered to herself.

"Tell me...about...it..." Luan panted as she lay on her back, enjoying the sensation of waves of pleasure crashing into her. Lisa was no Lincoln but she got the job done. Luan could respect that and if nothing else she could also take one of those pills and return the favor.

While Lisa and Luan were busy with each other's company, Lori was licking her hand clean after making Luna literally melt in her hand.

"You really are a minute man, aren't you?" Lori said once her hand was clean. She proceeded to wipe the rest of her face clean while Luan regained her breath.

"Are you kidding me, bruh? You fucking played my dick like it was a fuckign flute! There was no way that I was gonna last long from that!" Luan protested.

"Well how about you get hard again so that we can continue putting that new dick of yours to the test." Lori said as she pushed Luan onto her back on the other side of the mattress.

Straddling her sister in the 69 position, she allowed Luna to eat her out while she worked on waking up Luna's new friend from his nap. Cupping the balls, she gently began to fondle them as she took the half limp penis into her mouth. She sucked out the remaining semen still within the tube and then used her tongue to stimulate the head before running her tongue down the rest of the shaft. Luna squirmed beneath her and she was barely able to focus on her task.

"F-F-Fuck!" Luna gasped. "Dude...it's like you're trying to suck out my soul through my dick!"

Lori grinned. "That's the idea."

Bobbing her head up and down, it didn't take long for Luna's dick to get hard once more. And once Lori was satisfied with its level of hardness, she quickly changed positions so that she could mount it.

"Um, Lori? Shouldn't I be the one on top?" Luna asked as she watched her older sister straddle her.
But Lori just gave her a predatory smile. "Nope. I'm literally gonna fuck you until you cum dust."

The way that Lori said it sent chills down Luna's spine and she idly wondered if she would even survive having Lori fuck her like a cowgirl. She had seen her go for over an hour while riding Lincoln and she knew that she wasn't going to last anywhere near that long!

But before she could protest, the words got caught up in her throat as Lori began to buck against her hips, thrusting Luna's penis deep inside of her. The sensation of fucking and being fucked were totally different to Luna and she was definitely being fucked. She had no control over the pace or the rhythm as she was forced to try and keep up with Lori. When Lincoln had told her that Lori had two modes; sub or dom, Luna hadn't believed him. But now she was regretting not paying more attention to him.

"Come on, Luns, this can't be all that you've got!" Lori said as rode her sister like a bull. "Show me that you know how to rock with that cock!"

Praying that Mick Swagger would give her strength, Luna gritted her teeth and she reached up and grabbed a hold of Lori's shoulders and flipped her onto the mattress. But before she could capitalize on her move, Lori grinned before she wrapped her legs around Luna's waist and braced herself on the bed. Then she continued to buck against Luna's hips and she still maintained control. Only now Luna was quickly losing strength in her arms to hold herself up. With each thrust of Lori's hips she felt herself get pushed closer to the edge. Her breathing was coming in shallower and she was moaning like a bitch in heat, which technically she was but that wasn't the point!

"That's it...come for me, Luna..." Lori whispered into her ear before she began to nibble on it.

That had been all that Luna was able to take. With a grunt, she felt herself release her load into Lori's womb and within moments she collapsed into Lori's sizable chest. She was panting hard given how spent she felt and she couldn't feel her legs at all. Just what the hell had Lori done to her?

"You did good, Luna, you did real good..." Lori said, not sounding winded in the slightest but still satisfied. She was running her fingers through Luna's hair, playing with it absentmindedly. "A couple of more rounds and you might almost be good enough to satisfy Leni."

"W-What about...you?" Luna asked.

"Oh we're not done yet..." Lori said with a grin that sent shivers down Luna's spine once more. "You got to come but I didn't yet. So we're gonna keep going until you've made me cum enough times to satisfy me."

"But bruh, I'm completely spent!" Luna protested.

"Oh don't worry, I know something that will get you going once more."

Lori reached over the side of the bed and grabbed something that Luna couldn't see. She heard a squirt of something that sounded like lube before she felt something cold and slick prob her anus.

"W-What are you doING!"

Luna felt Lori push a small oval thing with a cord into her butt and she was positive that it was a vibrator. And before she could say anything else, Lori turned it one and Luna almost came once again as the vibrations sent a pleasurable feeling all throughout her body.

"With this little toy in your butt you will be able to keep going and going and going..." Lori said.

Luna could only gulp as she looked into the eyes of her dominating sister.

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Lisa looked over at the passed out bodies of her siblings. After an all nighter having sex, they finally fell asleep just as the morning sun began to rise. In the end it had taken all three of them, Lisa, Luna, and Luan, to fuck and finally satisfy Lori. It seemed that only Lincoln knew where Lori's weak points lay because try as they might they were fighting an uphill battle.

Still, the pills had worked out just as they were meant to. Each penis pill lasted an hour so taking more than one extended it by the same amount. The aging pill lasted four hours and Lisa surmised that it wasn't safe to take more than one at a time. Even when she shrunk down to her small stature, she still kept the replica of Lincoln's penis much to her joy. It had been amusing to see Lori lift her onto her shoulder and suck her dick while Luan and Luna double teamed her.

Next she would have to test out the gender swapping pills. The only question was how she was going to convince her brother to willingly take them...

Decisions, decisions...

End of chapter.
