Juvenalas Penitatas
Lesson 4 - Rilka's Relief

Rilka was normally a sound sleeper, and Talek had largely adopted the same trend. It was surprising how a place of such misery could also be, in its own way, a safe and comfortable space. The big, circular bed had a form-fit mattress that held the sleepers however they lay, the duvet was heavy and warm, the pillows numerous and the padded 'breakers' could be used to provide firmer surfaces as needed, bracing a Penny who wanted to sleep on their side, or holding the duvet off their scale to avoid unwelcome friction against a well-punished hide. Aside from pain or fear, lust was the main cause of unrest.
Talek was, physically, nine years old. Mentally, he was sixteen – and his brain hadn't gotten the message upon becoming a little-one once more. The first month in this new home had been hell because of the near-permanent erection he'd carried, small as it might have been. The gift of being allowed to masturbate after his first week, albeit with every member of the family watching him do it, had gone a long way to calming him down. He wasn't able to jerk off as often as he wanted to, but under his father's gaze he'd beat one out in the back garden just the other day. He was currently a little bit chubby on account of how nice Rilka smelled, but it was all more than manageable. He could have happily slept.
Unfortunately, Rilka was being a squirmer tonight, and the aforementioned 'niceness' was the cause. Feminine moisture had soaked into her pyjama bottoms, and the only way out for the fragrance was to drift up the channel between their bodies and escape right past Talek's nose. The 'chub' was going to be full-on hardness by the time they were roused for breakfast.
Once all the basic needs were tended to, Rilka's first port of call was her diary. She fetched it from the bookshelf and opened to today's page before giving a little whoop of joy. “Finally!” she cried, leaving the book out in full view, with today's page open, as she hurried out onto the corridor as quickly as any Penny dared to move. “Daaad!” she called downstairs. “Can you come up here, please? I really need to talk to you!”
She stepped back inside and hovered at the door, fingers fumbling with the frilly waistline of her freshly-donned tee-shirt. Shon entered with the look of a man who had been pulled away from some urgent task. “Yes, Rilka?”
The girl gave a shy little gulp. “It's... been six months since... you 'helped' with my needs.”
“I don't follow,” he answered.
The cream-coloured lizard girl made a huffing sound, one that was dangerously close to rude. She checked her tone and posture, becoming extra-polite. “Daddy... I would like to have an orgasm, please.”
Realisation dawned. “Oh! It has been six months since your court-approved 'self care' time, hasn't it? Alright, I will get the mat for you.”
“Can't you-” she began, but the protest was instantly cut short by the scowl.
“We do this properly, or not at all!” It was obvious the little lizard wanted to protest further, but she held her tongue. “Slip out of your clothes, then. Talek, this isn't a punishment so you don't have to go bare if you don't want to. That said, I have a sneaking suspicion your 'sister' would very much like to see you in bare scales while she's having her cunny massage.”
The passing comments turned Talek's snout the colour of beetroot, but Rilka's shyness had apparently gone altogether. “Oh, I can't wait!” she cheered, tossing her clothes onto the bed with playful flicks of the wrist.
“What did he mean about a mat?” Talek asked, his gut instinct being that it was some foul form of torture device. His inner eye conjured a metal rack with a thick, black dildo that squirted hot sauce or ginger-laced water into the victim over and over until they came out of sheer overstimulation.
“It's a special mat with restraints and stuff,” she explained, a little less giddy now, “I'll be strapped down all exposed, dad will put a bunch of sensors on my head, and then the computer built into the mat can monitor my stress levels. It knows how close I am, and it knows when I've finished. Like, fully finished. My friend, Lusu has one as well, and she's a greedy girl! Last time she got three orgasms rubbed out of her before the machine threw up a red light!”
“So dad's going to... tie you down and make you cum over and over?”
Talek's lustful awe made Rilka grin. “Not likely. I got one last time and that was it. Lusu gets off on 'overstimulation', but I hate all that! The machine goes red as soon as I squirt! That said...” her tone dropped as she drew in close to whisper, “last time, before bed, dad took me downstairs and let me watch a movie on his lap... and he rubbed me all the way through. Really slow, really gentle, teased me with the softest of strokes until I was dribbling onto his lap, then quietly curled a finger up inside and drew slow, careful circles right in my sweet-spot. We were both totally silent the whole time, like nothing was happening... and when I came, he stopped straight away, let me ride it out, then wiped the wet on my snout without ever looking away from the holo.”
The girl's lustful tone shifted instantly into a playful giggle. Talek knew exactly why – her recounting of father-daughter masturbation had left him fully-erect, and having undressed as his father suggested there was no hiding his desires.

The mat arrived in Shon's hands, and he carefully set it up in the middle of the floor. “Down you get, pet!” he said pleasantly, letting the girl settle onto her back before slipping sturdy leather cuffs over her wrists, ankles, thighs and tail. These were then bound to anchor points that left her utterly exposed and helpless, with paws closed around grips and legs tucked up against her little chest. Next came the aforementioned sensors, which Shon checked a few times before consulting a small, black device on his wrist. “Well, your 'base' is pretty high. You are needy!”
“Having Talek here is... a distraction,” Rilka confessed, glancing at the giddy little erection hovering close by.
“I'm sure he is. Talek, I know this is going to be exciting for you, and you are well aware by now that 'privacy' isn't a thing even in these matters. You can watch all you like, but you must not involve yourself in any way, is that understood?”
“Yessir!” the boy squeaked.
“Good. Also, I hope it goes without saying that you do not have permission to masturbate. That little stiffy is going unattended.”
Happy his son knew his place, Shon gave the cream-scaled lizard his full attention. He settled down on the floor next to her and gently stroked a green finger over her slit, coaxing out a sharp intake of breath from the helpless girl. “Tell Talek how my little girl takes her 'me time',” he commanded in a gentle voice as his digit gave another gentle pass over the seam of her lower scale.
“She... is still, and quiet, and doesn't beg!” Rilka replied, her eyes sliding shut as her father's touch sent tingles through her body. He pressed a little firmer, forcing the scale to part and allowing the soft, pink flesh beneath to feel more friction. Another, deeper huff came from her snout.
With first and third fingers, Shon splayed her open, exposing her tiny little passage to the world. The scent of her crotch wafted out, making Talek's cock bounce hungrily, but Shon was content to keep up the slow, careful teasing.
“It's important we take our time with this,” Shon said, his eyes fixed on Talek. “She may be a lustful little thing right now, but we want to make sure that she's fully ready for my finger. The last thing we'd want is to put it in too soon, or too forcefully, and cause her discomfort.” He gave a few more slow passes, each stroke making the Karrian girl tense up and breathe in sharply. “Come round here and get a better look. Watch now.”
The boy followed his father's finger on its caress. As he curled it away, the tight little opening to Rilka's cunny twitched, then slowly relaxed again. Shon waited a few beats before stroking again. Each time, the pause before relaxing grew slightly longer, and sometimes she would clench two or three times before calming. “You can smell her excitement, can't you? Look as well how her skin is becoming a fuller pink, and see the little shine of wetness? She would very much like me to enter her now, and if I let her beg she absolutely would. But we're still within her tolerances, so we're going to keep going like this.”
“Does she- does Rilka like being edged?” Talek asked in the hungry manner of all teenage boys given access to smut.
“No, she does not. Little miss Rilka hates edging, overstimulation, rough-sex, anal... she's a very vanilla little thing when it comes to her 'me time' activities. But, as I said, this is...” he trailed off, checking the coloured bars on his watch for a moment. “Are you sure it's been six months, Rilka?”
“Y-yes!” she gasped, her passage shamelessly gulping at the two males.
“Alright. Time for the main event then,” Shon confirmed, and slowly eased a single digit inside his daughter. From the twist of his paw, Talek guessed he was massaging her 'front', seemingly curling the finger up to find the 'rough patch' that all Karrian girls had there – or so he'd been told.
Whatever he was touching, it got an overt reaction from Rilka. She arched her back as much as her bindings would allow, toes curling as she tried to find purchase and change posture to place the intruding finger exactly where it was needed. “J-just a little-” she began, but her father's finger instantly withdrew.
“And that's a time out,” he said flatly. “Ten minutes to cool off.”
“Dad-”
“Now it's fifteen. You know not to beg,” he added with a wag of his wet finger. With that, he took Talek by the paw and led him downstairs, leaving the girl to whine and huff alone.

Shon parked himself in a comfortable chair and made Talek set on his lap. “What about you, little man? What are your preferences with this kind of thing?”
“I... have a bunch of stuff I like... in porn,” he managed, his face the colour of a well-spanked backside.
“Not much experience with the real thing? No shame in that, especially at your age. I don't expect you to be some kind of expert, Talek, and I don't want a clinical analysis. We'll get that later. For now, I just want to know your general likes and dislikes. For example, the ban on self care. How does that make you feel, not being able to masturbate.”
The boy's snout scrunched up. “I hate it!”
“And when you had to rub one out in the middle of your room, with all of us watching, how did that feel?”
Talek shook his head, “I didn't like that either.”
“Then what would you enjoy? No shame, not at all.”
Somehow, the blush grew darker. “Furry girls. Jalaxians, or Aspatrians, any girl with lots of fur. Whiskers are a plus. I... want to have sex with a girl who has fur.”
Shon gave a thoughtful smile as he considered something. “Just girls? No interest in boys at all?”
“No!” the reaction had teeth, and Shon sensed he was pushing this private talk a bit too far.
“Okay, okay, no more questions.”

The pair returned when time was up. Rilka lay quietly on the floor, not that she had a choice, and Shon saw no need to inform here of what was to come. He started over, resuming with the gentle teasing of a finger's caress on the outermost scale and working in with torturous slowness, one eye on the monitor band, the other on his helpless daughter's privates. She came to readiness faster than becore, and Talek could see by how she bit her lower lip she was determined not to blow it this time. The finger curled in and got to work, teasing and caressing, seeming to probe a little more than last time and following the huffs and whines coming from Rilka's maw.
Almost like a count-down, a soft beeping began to sound from the mat itself. It grew in tempo as Shon's rubbing grew more forceful, until four quick beeps came in succession and Rilka arched her spine, thrusting her hips as far up as she could-
-and Shon pulled away, denying her at the very last moment. “D-dad!” she wailed, humping at nothing in frantic attempt to slip over the edge.
“Are you sure it's been six months, cream-cake?” he asked sweetly.
“Yes!” the reply came, much too forcefully for any Penny's own good. “I know it is! It's in my diary and everything!”
“Little lady, that tone is completely unacceptable!” Shon barked, going straight back into disciplinarian mode.
“I'm sorry! I didn't mean to shout! Please, daddy! You know I hate this!”
“Of course you do. You know I wouldn't deliberately keep you on edge on your care day,” he answered, all transgressions seemingly forgiven.
Back to work he went, finger worming in, making the bars and monitors dance. So overworked, the girl took no time at all to get back to readiness, her warm, wet passage clenching hungrily against her father's finger as the warning beeps began again. Closer and closer, faster and faster, the caress of her inner space pulling the girl to the very brink again... and yet again, nothing but denial.
“Daaaaad!” the helpless girl wailed, thrashing in her binds as Shon calmly wiped his finger clean of her moisture.
“Do you mind if I check your diary, just to be sure?” he asked politely.
“Yes! It's right there, go read it! Look!”
Shon fetched the book and brought it over. “Mhmm, you put it right here, just like you said. But... if I were to back about five months... look! Here's a page where you admit to having pleasured yourself.”
The girl's eyes went wide in desperate horror. “B-but you knew about that! You caught me and punished me!”
“The rules are that you get relief once every six months. It's not been six months since that dalliance, has it?”
Tears began to roll down Rilka's cheeks. “But... but you... bound me like this and touched me!”
Shon smiled gently at the frustrated little Penny. “It technically doesn't count if you don't finish. You can ask to be touched whenever you like, little miss, and it's up to your mother and I whether we agree to it. We're happy to give you a little bit of huffy fun once in a while, as long as it doesn't go anywhere.”
“You... you knew,” she whimpered in a broken little voice. “You've known all this time...”
“Yes I have. Now, I'm going to give you one more quick rub, then you can have another time out.”
“Noooo!” what had seemed to be a tender act of kindness now revealed itself for the true act of cruelty it was. Rilka, a little girl who hated edging and orgasm denial, was going to endure both. Talek felt nothing but shame as he watched, his own twitching cock expressing his enjoyment for seeing a girl bound, teased, and denied in such a way... even though he himself would hate being in her place just as much. Shon, against his prior word, seemed not to care at all how much his daughter writhed about in her binds, nor did he pay any heed to the desperate begs for mercy coming from her maw. When the beeping came again it was like a countdown to cruelty, and Rilka was sobbing so hard it was as if she'd been spanked. Edged closer, and closer, and closer until just a single flick of the digit more would have at least given her a ruined release... but not even that came. All that was left was a long, mournful howl of lust denied, echoing from the throat of a desperate little rejuve who knew relief was at least thirty days away.
“I'm going to let you settle down again, pet,” Shon spoke again in that 'kind' voice he used, now all the worse for the harsh realities of what he had done. “Talek, you can stay here and keep her company. But you are to behave, understand? You can talk with her, you can ignore her, but you keep your hands to yourself, and you keep them off that guilty little stiffy. When I come back, Rilka can have some more cunny-rubs and we'll talk about your interests a little more.”
The final words drew another sob from the captive girl. Talek, on the other hand, felt utterly sick to the core. Not only was the the hardest he'd ever been in this house, with a big bubble of pre leaking out from his shaft, but his excitement and pleasure had come at the expense of the only friend he had in the world! “Rilka... I'm so sorry. I... I hate myself for this!”
No reply came. It seemed she hadn't heard him, or didn't care to reply. Her eyes were clenched shut, quietly leaking tears as she huffed and blubbed. As Talek watched her wallow in misery, he resolved himself to do at least one decent thing for her.
He lay down on the floor between her legs, shuffling forward on hands and knees, bringing his snout level with Rilka's musky slit. “W-what are you doing?” she whimpered, trembling at the feeling of breath upon her thigh.
“I'm going to be nice to you,” he answered, and let his tongue lap over her folds.
The girl shrieked in alarm. “Talek, no! You can't do that!”
He ignored the protest, pressing his lips firmly against her passage and working his tongue inside. Her hot inner space was warm and wet, her fluids carrying a metallic tang distinctive to Karrian sexual fluids. It was a taste he loved, and he hungrily fished for more.
“Talek, I'm begging you, stop! Please!” Rilka wailed, but Talek only had ears for the mat. He twisted about, searching with his tongue for a spot he knew had to be – there! His sister gasped, her whole body trembled, and below him a slow beep began.
Now he knew where her sweet-spot was, Talek lapped at it as fast and hard as his tongue could manage. No matter how his sister begged and squirmed, the steady beeps told him he was on course. Faster, faster, he put as much force into lapping her twitching inner passage as he could, knowing that she had to be close simply by the trembling of her body. He didn't need the matt's long chime to tell him Rilka had come – the squirt of fluids straight into his maw was all the evidence he needed.
“There you go,” he sighed, pride dripping from every word. “You got that release you wanted, and you didn't touch yourself!”
Through the haze of horniness, it was slowly dawning on Talek that this was probably not the genius workaround he thought it was, given that Rilka's expression was one of mortal dread. Any remaining doubt vanished when their father returned, stone-faced and eyes wide in rage.
“Dad?” Talek asked, cautiously. No reply came. The silent adult approached the boy quite deliberately, making Talek retreat a few paces before the gap was closed.
Shon never broke eye contact. He raised his wrist and tapped some buttons on the wrist-band. From it came a recording of Rilka's voice. Talek, I'm begging you, stop! Please! Shon let the recording play three times before silencing it. “What did you do?” he asked, cold as ice.
“I...” Talek began, but his mind seized up. He couldn't focus enough to even come close to explaining.
Rilka, bound still on the floor, tried to answer for him. “H-he licked my c-cunny, dad.”
Shon focused on the girl, kneeling down beside her and softly caressing her dark blue hair. “Are you okay, little one? Are you hurt?” Rilka shook her head frantically as the binds were released. “Alright. I just need you to sit there for me, okay? I need to deal with Talek now.”
When he rose, it was akin to a storm front barrelling down upon an undefended shore. “Talek, you are in more trouble than you can ever imagine! What the hell were you thinking?”
“I... wanted her t-t-to f-feel good!” he whimpered.
“Feel good?” Shon echoed. “You raped her, Talek!”
“No!”
“You violated her sexually! You forced you tongue into the genitals of a helpless little girl! What would you have me call that, Talek? I have the evidence right here! The moment this is uploaded your days as a 'juvenalas' are over! You will be taken to the courthouse for sentencing, and you'll be coming back to this house not only as a hard-time penitatas, but as a six-year-old girl!”

What followed were two events that played out simultaneously. The first was that Talek broke, and broke utterly. He fell backwards as if punched, howling as if his soul were ripped from his flesh. It was not the cry of a child in pain, or a boy in fear, but of absolute, total grief. It was the sound of a boy mourning the death of his former life, having realised in the most absolute of terms that he was a dead man walking.
The second was that Rilka flew at him like a cream-scaled missile, hammering into him and clutching him so tight he couldn't draw enough breath to cry. She put herself directly between the boy and her father, her own tears soaking her cheeks and dripping onto her beloved brother. “It was all me!” she blurted out. “I forced Talek to do it! I faked being upset to frame him!”
Shon's jaw fell open as the girl continued her suicidal tirade. “I'll tell the court that recording is a fake! I'll tell them you're lying, and so will Talek! We'll both tell them it was me and he's the victim here! You aren't going to destroy him over this!”
The passion of her defence broke through Talek's terror enough that he could see the confusion in Shon's features. When he finally broke the silence, addressing the girl who now broke down and bawled into Talek's chest, he spoke with a genuine tone of concern. “Rilka, honey, I think you and I have a lot we need to talk about. Right now. I'm going to be waiting for you downstairs, so I want you to calm yourself and then come sit with me for a while. Talek, all I can say to you right now is that you are in a lot of trouble... but not as much as you think. That was a stupid thing to do, and you are going to hurt for it, but some of the things I said just now... you'll still be just as you are now when we're done, okay? What 'officially' happened here... maybe we can bend the truth a little bit. Maybe... certain files will 'accidentally' get deleted. It'll be bad, just not world-ending bad. Okay?”
The boy could only nod mutely in confirmation, but that was good enough. “Downstairs when you're ready, little one,” Shon repeated to Rilka on the way out.

Talek never found out what exactly was said between the two. He certainly wasn't going to ask. All he could do was lay on his bed and whimper in numb dread at the prospect of what was going to be unleashed when his father reappeared. When that moment came, Shon was terribly calm, like an iceberg is calm when drifting through a shipping lane, or a meteor is calm when approaching an unsuspecting planet. He came to rest upon the circular bed and fixed a disapproving stare at the whimpering little lad, with just a brief detour to collect some punishment implements. “You and I need to have a talk about consent,” he stated.
“I-”
“Not asking for your input,” Shon cut in. “You are going to lie over my lap now. I am going to talk, you are going to listen, and then when I'm satisfied you understand what you did wrong I am going to hammer the lesson home.”
Shon took Talek's tail in a firm grip and held it upright. His other hand took up the tail strap – a hateful little band of brown leather with a jolly red hilt that belied its cruel nature. “You and Rilka are penitatas. I know, you're a 'special case', but the point remains the same; as rejuves subject to correctional measures, you do not possess any means to consent to anything. You cannot give informed consent to interact with anyone, to purchase anything, or to engage in any activity. The default position for every single thing you do is 'I cannot do this', until consent is granted by a legally-appointed authority figure. Do you understand that?”
“Y-yes,” the boy whimpered.
“Do you really? I hope so. Now, this power of consent lies entirely with your mother and I, but it goes beyond that. We not only control what you can and cannot consent to, we are legally empowered to ignore and go beyond normal civic restrictions. This is why we can spank you two so harshly, and why we can force you to live under conditions that would be deemed cruel for a regular 'kindern', or even any other class of rejuve! Do you understand that, Talek? I want you to prove to me you understand.”
Talek nodded timidly. “Y-you can d-do stuff we can't... and nobody else can... s-so... it...”
“Yes?” Shon lightened his tone, sensing they might be on the verge of a breakthrough.
“S-so it was 'gainst the law for me to d-do sex stuff wi' Rilka, 'cos s-she can't consent.”
“Very good. Nor can you. The problem, you see, is that penitatas are not kindern – if you were 'real' eight and nine years olds this kind of fooling around would be different. Frowned upon, yes, but you wouldn't be deemed legally able to understand the consequences. As a juvenalas or a penitatas you are legally responsible for your bad choices!
“You breaking our rules and pleasuring yourself? That would be bad, but it's bad because you're disobeying your guardian. You and Rilka having sex? That would be worse. You performing sex acts on a helpless girl? One you knew was being restrained against her will? Talek... do I need to explain to you why that was bad?”
Talek let his tears answer for him. Somehow, being questioned in a concerned, fatherly tone was even worse than being yelled at. “s-sorry!” he managed.
“I know. I want you to understand one last thing before I start, Talek: I'm not going to go as hard on you as I can. I'm deliberately cutting you slack because, more than anything, I need to make sure you two are both back on track. This whole thing... it's derailed you both. I know that. This is just enough to get you good and sorry. We'll take the rest as it comes, okay?”
“Y's”, the rejuve blubbed.
The strap found the base of his tail, swift and hard. Already a wreck, his loud howling was more fitting for a rejuve half his physical age, and far louder and more desperate than the pain of the strap alone deserved. Shon knew his boy was bawling out his emotional distress too, and that was welcomed. Steady, rhythmic slaps echoed through the bedroom, each given enough pause for their stinging lesson to fully soak into the tender flesh and thin scale of the tail base.
“So-reeee-eee!” the youth howled as the belting did it's thing, coaxing out every last drop of pain, fear and grief the boy had inside of him. Though he'd promised only the tail, Shon changed focus to work down the boy's cheeks, turning his green-scaled buttocks red with strong, steady slaps. This brought panic to the crying fits, but the experienced father knew that by spreading the smacks he could change the focus, and prevent unwanted bottling up of feeling. 
“Okay, let it all out now,” Shon soothed the boy, running a dark green lizard paw through the boy's black hair. “Once you've settled a bit I'm going to bring Rilka back up here with your mother and we'll all have a talk to make this right.”

The family meeting was done in laps – Talek on Shon's, Rilka on Liki's. Both pennys were firmly held, but in a comforting way rather than a restrictive one. Rilka's bottom and tail showed no signs of parental attention, but her eyes were wet and heavy. Nobody spoke, though Talek got the distinct impression his parents were silent due to wanting them to go first.
“Rilka... I am so, so sorry for what I did to you. I promise... I'll never touch your privates again.” Shon leaned in and whispered one little correction that made Talek blush, despite the knots in his chest. “I... will never touch your privates without permission again.”
Rilka's eyes stayed fixed on the floor. “Talek... I used to be a man. I was twenty four and I... got into a relationship with a fifteen year old boy. A sexual relationship. We met up a few times and, at the time, I told myself it was consensual. He... he seemed to like it. But we lost touch after about six months, and then years later he found me again. He had a hard time dealing with our 'relationship', and he felt used by me. He was going to go to the authorities over it, so I turned myself in. I honestly never wanted to hurt him, but I did. I used him. That's why I'm a girl, and that's why my parents do a lot of... sexual things to me. You coming here was my big chance to prove that I could be a healthy, happy, normal girl. I... messed that up on the first day, didn't I?”
“Rilka, I... I don't know to feel about all this... this is really hard...” as he trailed off, a kind, fatherly paw stroked his head.
“Take as much time as you need to get this right,” Shon assured him, while Liki seemingly gave similar encouragement to her charge.
To carefully fill the long silence that followed, Liki spoke across the circle. “Talek, do you like Rilka? Or are you just attracted to her body.”
“I think I like her,” the boy mumbled.
“I like you too,” Rilka confessed.
“And do you want a sexual relationship with her?”
The timid little boy glanced upward at Rilka's pained, yet earnest face. His eyeline took in her little slit and flat chest along the way, which the subtle little clench of scrotum appreciated. “I... I'm not allowed, am I?”
Shon stroked the boy's head again. “If we allowed it, would you want a sexual relationship with her.”
“Y-yes,” he answered with a blush, and the matching shade on Rilka's face was answer enough.
Liki and Shon exchanged their dreaded 'parental grin' with one another. “Then here's what I propose,” the mother said. “All the current rules apply to you both – no sexual contact, no masturbation. While you're in the house you can undress whenever you like, and there'll still be no shame for being stiff. As long as there's absolutely no physical contact, we will let you 'tease' each other all you like.”
“If you 'accidentally' touch each other, we expect you to confess immediately,” Shon added. “If it's a genuine accident we'll give you a time out to calm down, and so long as you do calm down that'll be the matter settled. If you are deliberately flouting the rules, we will go hard on you and take away these little leeways, understood?”
“Next.. and this is the rope,” Liki let the term hang in the air so both rejuves understood the meaning, “from now on, we'll give you half an hour of 'dimming the lights' at bed time. As long as nobody 'finishes', we don't mind what you do. You can kiss, you can touch each other... we'll even turn a blind eye to sex. So long as you are both still as pent up as when you started, or more as the case may be, mommy and daddy will pretend it never happened.
The mother's words made the pair a little puzzled, and somewhat anxious, but Shon's grin suggested he was looking forward to what came next. “If our little ones are very, very good, we might even let you have 'me time' earlier than expected. But that's conditional on you being good as gold!”
“Does all of that sound fair?” Liki asked, and as if her kind tone didn't make it clear she added, “we want your honest feelings, so speak up if there's anything about that you don't understand or find unfair.”
“So we can... edge each other... but still only get to actually jerk off once a month?”
“Or once every six months for Rilka,” Liki confirmed. “But like your father said, we might change that.”
Talek glanced away from his mother and back to Rilka. There was a certain... hunger in her eyes. “I guess... if Rilka wants it too? Okay.”
The grins of the parents grew wider, and Rilka began to tremble as a giddy smile spread over her snout. Liki, paws on the girl's shoulder, spoke for her. “Then, Talek, I am willing to consent on Rilka's behalf... to sex. Full, vaginal penetration, and riding to climax.”
“Do you want that, son?” Shon chuckled.
“Y-yes!” he looked at Rilka's smug face and realised she must have been in on it before coming upstairs. “I would love to have sex with you, Rilka!”
Shon popped his nude little son on the floor, the nine year old's boyhood ramrod straight in anticipation for the coming gift. Rilka crawled over, slow and sensual, shaking her tail and playfully pawing at him as she straightened up. A soft kiss was planted on his snout. “How does a little girl take her 'me time', Talcum?”
“She... is still, and quiet, and doesn't beg,” he replied, quoting the mantra she'd uttered when bound to the masturbation mat.
His words delighted Rilka as she shuffled herself into place. “Good girl, Talcum! Now let's see if you can manage it!”
Slowly, inch by inch, the cream lizard lowered her body towards Talek's green hips. The moment came when his cock felt a pressure that bent it downward, and Rilka paused there until a helpful mother gently took the wayward stiffy and pointed it to its proper place. A low whine of delight slipped from Talek's maw as he was enveloped, sliding slowly, inexorably, into the blissful embrace of Rilka's cunny. Her warm folds held his Karrian meat like a velvet glove, and the penny girl seemed content to simply sit upon his pole and cuddle. He was certainly not going to object either, as even when quite still the subtle motions of her body gave a tickling pleasure to his length.
Clearly understanding their part in this, Liki and Shon softly began to rock the pair. Rilka's words came to the boy's ear-slit, whispered so soft he strained to make them out. “Go limp... except in there. Let it happen... good Pennys accept their fate... good Pennys only cum when mommy and daddy make them cum.”
The teasing, childish words had an unexpected impact on Talek's groin, making it jump and squirm. He did his best to be limp and trust his father's paw to hold him upright. He fought the urge to hump, so his stimulation came entirely from the soft rolling of Rilka's hips.
Up until that moment, Talek had hated the helplessness his parents forced upon him. Now... it was the best thing ever.
He came, suddenly and with only a soft gasp. It was long drawn out, his meat spasming in time to the purposefully slow rocking of the girl in his gentle embrace. The only acknowledgement he got from anyone as to his climax was a subtle huff in the ear from Rilka's nostrils. The twitching slowed, the last of what little spunk his tiny balls had was coaxed out, but the rocking continued. He stared into his mother's smile, lips tights closed, and thought he saw a little twinkle of awareness... but nothing changed.
They rocked together as Talek went soft, then over many long minutes rocked him back to tender hardness. Despite his louder, blunter huffs and the tightness in his muzzle, this drawn out forced-sex continued. 
“Do you think they're done?” Shon asked quietly.
“I'm sure they'd tell us if they were,” Liki replied firmly.
Rilka giggled, just once, into his ear. The lad's tender length had twitched at the fake-ignorance of his parents. Over a long, and wonderful evening he was edged back to full hardness and kept there, too spent to cum, while little Rilka grew more huffy by the minute. The spasm and yelp of her orgasm was the sweetest sound Talek had ever heard, and he responded with a dry orgasm of his own. A few long rolls later, and Rilka whimpered out a little plea for mercy. Their 'kindness' complete, the parents left their little charges huddled in place, exhausted and sweaty, but neither willing to move an inch.

They were, without doubt, the happiest penitatas in the universe. At least, for one night.
