Chemical ran into the bedroom, looking for a place to hide. Under the bed? No too obvious. In the bathroom? She'd definitely be found. The closet? It would have to do. She opened the sliding door, and quickly shut it, then perched herself on some boxes, her body fairly well concealed by the all the hanging clothes. She calmed her breathing. A beat passed. The bedroom door slammed open.

"Come out, come out, little mare. I'll be nicer if you come out on your own." There was no way that was true. It had to be a trap. She should stay in the closet. "I'm going to sniff you out soon, little mare. You won't like me if I have to be the one to find you." Chemical felt heat bloom in her lower abdomen. What? No, no, no, she couldn't— The closet door slammed to the side, and light flooded the closet. Chemical held her breath, staying perfectly still. Her pursuer growled, then retracted her head from the closet, and shut it. Chemical Instinct let out as a quiet a breath as she could.

SLMM!! The door was wrenched open and the Beast's hands reached out of the darkness and grabbed hold of Chemical's waist. She screamed as she was grabbed, hands scrabbling to cling to something and keep from being pulled from her hiding spot; to no avail. She blinked as she was dragged into the light, and flinched as she was turned over. Now facing the ceiling, she could see the face of the Shadow Roll Beast snarling above her. The Beast leaned down and put her jaws up to Chemical's throat, biting down lightly. Chemical whimpered. The Beast pulled back.

"I told you I'd sniff you out, pretty mare. Your scent gave you away like a signal beacon. You were never gonna be able to hide from me. Not with your greedy pussy trying to get my attention so much." She grabbed the sweatpants Chemical was wearing and yanked them down her crotch, taking the underwear along with them. The Beast shoved two fingers inside Chemical, who gasped, and writhed before the Beast's other hand closed around her neck, silencing her instantly. "Behave, you slut. That's right, feel how wet you are, you're nothing more than a bitch in heat, with the way you're leaking all over me right now."

Chemical could feel a gush of liquid come her pussy, and felt horror growing inside her. How was she being turned on by this! The Beast grinned down at her, clearly having felt it. She pressed down on Chemical's throat. She could still breath, but just barely. A third finger and then a fourth entered her. "Look at how easily you take me. You're already desperate for my cock, aren't you, whore?"

She shook her head and tried to say that she didn't but couldn't get any words out with the Beast's hand constricting her airway. Even though she could breath, it was so little, and she was beginning to feel lightheaded. The fingers inside of her moved and she could do nothing but take it, take the rough treatment. The hand on her throat pulled away, and she gasped for breath, a strange rush as her thoughts returned sharper than before. The Beast pulled her fingers out of Instinct's slit and then she was being lifted.

She shrieked as she was thrown onto the bed. She tried to get up and scramble away, but those arms, muscles like steel, grabbed her once more. "Don't try and get away, you're mine now, and I'm never letting you go." Something hard pressed against her ass. There was a whistling and then a sharp pain erupted on her butt as the Beast spanked her. "This," she grabbed Chemical's ass right where her hand had hit, causing her to cry out, "is mine. It belongs to me now. I'll do whatever I want with it."

The hard length pressing against her went away, and for a moment, there was silence. Then the Beast's hand was back at her entrance, but this time she seemed to be… coating her hand in the slick. The hand was soaking wet when the Beast pulled it down towards…Oh goddesses, please no! The hand rubbed her own slick onto her back entrance, and after only a few seconds, something— The Beast's throbbing cock, was pressed against her hole.

"Relax, or this is going to be even more unpleasant, slutty mare. I know you want this cock anyway, so why don't you make this easier and stop pretending?" Instinct shook her head, she didn't want the Beast's cock! "Well, if you wanna play hard to get, I'm not gonna argue with you, I'm just gonna fuck this ass, because it belongs to me already." With that, she began pressing in, and although Chemical Instinct did her best to keep the very large stallion out, gradually the head began forcing its way into her tight, mostly dry backdoor.

It hurt, Goddesses did it hurt. She'd never felt anything like the burning she was experiencing as the Beast's girth forced her open. It was agony. It was awful. It…was feeling kind of good…what? No! No, that couldn't be right! She couldn't deny it though…

The head was all the way inside and the Beast grunted behind her. She bodily grabbed at Instinct and forced her up against the headboard, pressing up against her from behind. She pushed inside in harsh, forceful thrusts, working more and more of her large shaft in without giving Instinct any time to adjust. The pain grew more intense, and… so did the pleasure. Why? "I can feel you getting loose and then tightening up again, pretty mare. I know what that means," the Beast put her mouth next to Instinct's ear. "That means you're a dirty, filthy whore who loves to be fucked in the ass." She wanted to deny it, so badly did she want to deny it.

She couldn't though. Because the truth was that it felt… incredible. The Beast's hips came to rest against Instinct's ass. She growled again, all aggression and totally feral. She bit Instinct's shoulder viciously, and began thrusting, pulling out at least halfway every time, then slamming back in. It was… incredible. It was the most pain she'd ever been in, but the best she'd ever felt. The guilt crawled down her back as the pleasure washed over her.

"God I love fucking a fresh tight hole like this. It's even more satisfying when they belong to a whore like you whose about to cum just from being fucked." What? She wasn't about to cum, there was no way! The Beast put one hand back on Instinct's throat and the other went back to Instinct's pussy, this time stopping at her clit. She began choking Instinct to the point just before her breath would be totally restricted and pinched her clit firmly. Chemical Instinct spasmed around the Beast's shaft as it plunged into her and pulled out again and again. Oh Goddesses, she was about to do it, wasn't she? She was right at the edge. It would barely take—

The Beast increased her rhythm, and pounded into Instinct, each impact feeling like it was going to leave bruises. She growled into Instinct's ears. "Fucking take it, slut." With one last thrust, she buried herself all the way to the hilt in Chemical's ass and started cumming. The hot, molten ropes of seed were so deep inside. The sensation was heavenly, and it was just what Instinct needed to climax. "Cum for me, pretty pony, cum right now to the feeling of me filling you up, breeding your tight ass." She shivered, pleasure pulsing through her core, clenching down onto the Beast. They both gasped.

Then the Beast began thrusting again. "You're mine," what, no? She wasn't ready, it was too much, she couldn't, "and I'm not—"

"Red!" Narita Brian stopped moving.

"Ok, sweetheart. That's perfectly fine. Let me get myself out, and then we'll be done." Very slowly and carefully, Brian pulled out of Chemical. When she was fully out, she turned Instinct around and hugged her tightly. "You were incredible, sweet mare. Absolutely amazing. I'm so proud of you for setting your boundary, too. Did you have fun?"

"Mmhm. It was really nice, ma'am. I enjoyed how you made me feel the whole time. You didn't do anything wrong, I just wasn't ready to keep going. I got overwhelmed, so I said our safeword." Brian kissed her forehead and rubbed circles onto her back.

"Would you like to get cleaned up, or do you needa minute?" Instinct kept her head against Brian.

"Can my Snuggley lie down on top of me, and cuddle me, please? I want you to be my safe place right now." Despite herself, Narita Brian couldn't help the little smile that came across her face.

"Yes, of course, Chemise." Brian, still hugging Chemical, turned them to the side, and slowly lowered them both to the bed. Then she turned them both over so that she was fully on top of Instinct, covering the smaller umamusume with her larger frame. Instinct sighed happily, feeling content and protected. She pressed a few kisses against her partner. Brian decided it would be a good time to ask, "tell me what you liked about the scene." Chemical Instinct hummed.

"Mmm. Liked how you were so growly and how you said my body belonged to you. That was so, so hot. You did a really good job being scary in a way that I couldn't help find attractive even with the scene being what it was. Thank you for indulging me, by the way." Brian hummed right back.

"You do so, so much for us. We wanted to do something for you, and I'm the one who could do this for you. I had a fun time too." Brian had a bit of a blush admitting that last part, but luckily for her Instinct was in no position to see it. They sat in silence for another few minutes. Eventually, Brian could hear that Instinct's breathing was beginning to even out, and she knew it'd be for the best they start the rest of the aftercare she had planned.

"Ok, good girl, it's time to get you all cleaned up. I'm going to take you to the shower." So saying, she rolled off Chemical, and stood up. She watched as her partner sat up and stretched, the size difference between them accentuated by how small she looked in the center of their large bed. Brian scooped Instinct up into her arms, enjoying the squeak of surprise she made and the way her feet kicked cutely in a brief panic. She looked up at Brian and pouted. Brian snickered at her.

They arrived in the bathroom, and Brian started running the water for a bath after placing Chemical down gently. She took the smaller uma's hand and held it while they waited for the water to warm up. Once it was an acceptable temperature, Chemical climbed into the tub, Brian continuing to hold her hand. She kept holding it until the tub was sufficiently full, then turned off the water, and released Chemical's hand so she could get in the tub herself. Settling in behind her petite mare, the stallion began lathering soap using a soft wash towel, and slowly cleaned her lover.

"Mmm, feels good Snuggley. Thank you for loving me and treating me nice." Brian kissed the back of Instinct's head and scratched behind her ears.

"Of course. It makes me happy to do this for you." Brian was rarely more forthcoming and vulnerable than when she did aftercare for Squeaky Clean and Chemical Instinct. Tenderly, she washed Chemical's intimate areas with a light touch, and then started conditioning her hair. Once Chemical's numerous locks were lathered, she let the mare rest against her chest, circling her arms around the smaller uma's waist. "Close your eyes if you'd like, Chemise. I'll wake you when it's time to shampoo and rinse."

"Nuh uh," Instinct denied. "I want to enjoy this moment with you. We can sit all quiet though. I just wanna be held by my Snuggley, so everything is perfect right now." Brian was again thankful that Chemical couldn't see her face, and therefore couldn't see the massive blush she was currently sporting. They did as Instinct suggested and waited in silence, basking in the warmth of the water and the presence of their partner. Finally it was time.

Brian got the shampoo ready much the same as the conditioner, slowly working it into Chemical's scalp before lathering it into the rest of her hair. Then she grabbed a small plastic bucket they kept by the bath just for this and began to rinse the neon red strands. The soap and conditioner were washed away, and soft, silky smooth hair was revealed. By this time, the water was starting to cool, so Brian began to drain the tub. She motioned for Instinct to continue sitting and then climbed out of the tub to rapidly dry herself off.

Once Brian herself was sufficiently dry, she grabbed two towels and wrapped Instinct up in them, before once again lifting her. This time she took her from the bath out to the living room. She placed the bundle of mare on the couch.

"Wait here for a few minutes, good girl. I'm going to get everything we need to take care of your hair and tail. Before I go, do you have a show you'd like to watch?" Chemical's ears flicked and swiveled as she considered the question, and then she nodded.

"Can we watch 'How It's Umade?'" Brian chuckled and nodded. Chemical was quite fond of the show, and honestly, Brian would have been safe to just put the program on without asking, but occasionally her Chemise wanted another form of entertainment or preferred to sit in silence after an intense scene, which tonight definitely counted as.

After getting all the supplies needed for proper hair, ear and tail care, Brian returned to find her mare watching the television with what appeared to be a rapt expression. Hmm…

"Chemical? Chemical Instinct?" Her mare didn't react. She was definitely deep in sub space. Brian brought placed everything on the couch and sat down, pulling Chemical into her lap. That was enough to bring her back to the surface somewhat.

"Hmm, oh hello, Sir. Oh, I'm in your lap. That's nice. Thank you for putting me there, Sir." Brian found this somewhat tired, blissed out tone very, very endearing, but she also needed to pull her mare out of sub space, otherwise she might experience a drop if Brian did something she wasn't expecting while she couldn't communicate her wants. She turned off the television, and that seemed to draw her out more. She blinked several times. "Wha—Oh? Oh, gosh, I must have… I'm sorry Snuggley… I was just so comfy and cozy on the couch with—"

"Don't worry, good girl. You're not in trouble, I just need you present and here with me so we can keep talkin' in case somethin' happens that you don't like. I'm goin' to get your hair lookin' all nice." Chemical nodded and turned back to the show, settling down again. Brian started running the brush through her hair, doing her best to be gentle with any tangles. Once she was finished, She carefully massaged Chemical's ears and moisturized them. Then, she wrapped the hair up in a t-shirt after lathering it with leave-in conditioner. Finally, she did the same process with Chemical's tail, though for the tail she did a French braid instead of wrapping it in a shirt.

"We're all finished, good girl. Are you ready to go to sleep?" Chemical Instinct nodded.

"Yes Sir, I'd like to go to bed with you now." Brian smiled at her Chemise. She turned off the television, picked up her petite mare once more, and walked calmly to the bedroom. She held Chemical Instinct tight against her, and when they reached the bedroom where some of the rest of the polycule had decided to spend the night, she lay the mare down in between two of the other stallions who were already asleep. Then she herself climbed on the bed, and just like after the scene, draped herself over the mare. They exchanged murmured 'I love you's' and allowed the comfort of the other's presence to send them swiftly into sandman's arms.

Chapter Text

Chemical Instinct knocked on the door to her lover's office. A muffled 'Come in' permitted her to enter. She opened the door slowly and quietly, trying to be as unobtrusive as possible. She went over to the desk and knelt beside her dominant. Mistress Kamehameha hummed to acknowledge Chemical's presence, and continued her work. After several minutes, her hand extended, and she placed it gently on top of Chemical's head, scratching between her ears. It was lovely. Chemical's gut churned with guilt. She didn't deserve this. It wasn't her place to question her dominant, though, so she remained silent.

"My sweet filly doesn't come to kneel unprompted unless there's she needs or wants to tell me." Mistress Kamehameha pushed her chair back from her desk and rotated to look down at her submissive, hand never leaving her head. "So, which is it this time, pet?" The deep voice of her dominant sent shivers down Chemical's spine.

"Your pony was bad, mistress. She did a bad job helping Ms. Squeaky get ready for her last concert. One of Ms. Squeaky's heels broke, and she fell. Your pony failed to notice the defect and… and… Ms. Squeaky could have… she might have…" Tears blurred Chemical's eyes. Her chin was tilted up, and Mistress looked her in the eyes.

"Hmmm… I think my pony is forgetting herself. I'm the one who determines if my pony is misbehaving. Is that understood? Nod 'yes' or 'no' for Mistress, pony." Chemical nodded 'yes.' "Good. Now, I understand it was scary to see Squeaks take a fall like that, but there was no way you could have known there was a flaw in her new heels. You're being unreasonable, and I think you know that. Do you understand?" Chemical couldn't help herself. She shook her head 'no.'

"No? If you don't understand, then that means you disagree with me. Careful pony, you're getting close to actually misbehaving." Chemical didn't want to misbehave, but she'd failed Squeaky. She'd screwed up, and it was only luck that Squeaky came out ok. She whimpered. Mistress sighed. "I don't like seeing you miserable like this, pony. Tell me what you need. What will make you feel better?"

Silence held the room captive for a moment.

"Your pony needs to be punished, Mistress. Your pony needs to be taught a lesson, so she doesn't make a mistake like that ever again." Mistress raised an eyebrow, and Chemical worried she'd overstepped, even if Mistress had given permission.

"A punishment. I can do that. But I want you to understand, pony. Listen, and listen well." Mistress stood from her chair, and then leaned down so she was next to Chemical's ear. "I'm not punishing you because you did anything wrong. I'm punishing you for thinking you know better than Mistress." She unbent and straightened her back and shoulders. Mistress Kamehameha looked magnificent.

"Get to the bedroom, and strip, then wait on the bed. It should be obvious, but you're being very foolish today, so I'll remind you not to touch yourself. That pussy belongs to me and me alone. Now go, I've got a few things to prepare." Chemical nodded her understanding. She crawled swiftly to the largest bedroom, knowing that was where her Mistress preferred to play.

When she reached the room, she quickly stripped her clothing off, and then folded and placed them on top of the nightstand. Mistress liked it when she kept things well organized, and she often asked Chemical to put the same outfit back on after play. Chemical kneeled on the bed and leaned forward with her hands placed in front of her, a position of atonement.

The door opened, and Chemical's Mistress entered. She paused in the doorway.

"So you do know how to behave after all. Good pony. That won't save you now, though I'm sure that's not what you want anyway." Chemical didn't. She needed to be punished. Needed to be judged for her transgressions. Mistress walked over and sat down at the edge of the bed. "Come get across my lap, pony, ass up." Chemical crawled over and situated her nude body on Mistress pants clad lap. "Good pony. I think 30 is a nice number of strikes. What do you say when you get a punishment, pony?" Chemical was practically vibrating with anticipation.

"Your pony counts and says 'Thank you, Mistress.'"

"Very good, pony, very good. Get ready." Chemical was ready. She'd been ready in her bones for this to happen since the night of the fall, and the overwhelming guilt had built until she had sought out her mistress, and now here she was.

Crack! The first blow came, and Chemical recognized, even as she cried out and her body reacted, that Mistress was using her favorite paddle.

"One! Thank you, Mistress."

"You're very welcome, pretty pony." Crack!

"Two! Thank you, Mistress." Crack-Crack! Two swift blows, one on each cheek. "Three, Four! Oh, Fuck! Thank you, Mistress." She could feel herself growing wet… oh gosh she hoped Mistress wouldn't notice. Slap! "Five! Thank you, Mistress." Only five in and her ass was already beginning to glow, she could feel it. She waited for the next blow to come, only…

"What's this, naughty pony?" Mistress Kamehameha covered her pussy with her much larger hand, pressing the wetness back into Chemical's slit. "Getting excited from your punishment, mm? What do you have to say for yourself?" Chemical shook her head.

"No Mistress, your pony swears it's just her body's reaction. Your pony would never take pleasure in her punishment on purpose, please believe that Mistress." Chemical whimpered a little, knowing how pathetic she sounded but unable to help herself. Mistress laughed and squeezed her dripping sex, hard. Chemical gasped. "I suppose you sound desperate enough that I can take you at face value, pony, but know that I'm watching you." Slap! Quicker than she could possibly process, Mistress let go of her pussy and smacked it with her open hand, using quite a bit of force.

"AAAaah!" Chemical Panted… wait, she needed to— "S-six, Goddesses, Thank you Mistress." Another pause, and silence was the dominant sound in the room, other than Chemical's breathy pants.

Smack-Crack! "Seven, Eight, Shitshitshit, Thank you so much Mistress." The paddle came down onto both of her thighs and Chemical could barely keep from writhing, which she knew would disappoint her Mistress.

"Get ready for the next one princess, I'm going to really let you have it." Oh Goddesses, a warning? Mentally, Chemical did her best to focus on keeping completely still.

Smack!-Whack!-Thwack!-Crack!-Slap!-Snap! Six blows. Each to the same spot on the right side of her ass… For a brief second, she didn't feel anything… and then—

"Oh Fuck! Fuck, Daddy, Please!" What had she just said, what had Chemical just done— Suddenly she was turned over in Mistress Kamehameha's lap, and her mind went blank as her Mistress looked into her eyes, searching for something. She couldn't help but hold her breath. The room was truly, fully quiet now.

"What did you say, pony?" Her Mistress' voice had a quiet intensity. "What did my pony just call me?" Chemical swallowed thickly, and opened her mouth to answer, not knowing what she planned on saying. "Y-your pony is so sor—"

"Not what I want, sweet Pony. Remember, I decide if you're misbehaving. Thinking isn't for silly ponies like you. Now, I'll ask you one more time. What did you call me?" Mistress' words gave no other option but to obey, so Chemical did.

"Your pony called you 'Daddy,' Mistress." Mistress Kamehameha's pupils dilated. She took a deep breath.

"I'm going to absolutely ruin you now, princess." Chemical was thrown onto the bed, and the sounds of a zipper being pulled down and a belt being unbuckled hit Chemical like actual aphrodisiacs. Instantly, she became dripping wet. The mattress sunk behind her, and she was pulled onto all fours before her head was pressed into the bed spread. Mistress breathed down her neck. "Say it again, princess."

Chemical knew exactly what she wanted to hear.

"Daddy." A hand wrapped around her neck from behind.

"Beg for it, princess. Tell Daddy how much you want it." Oh, that was… Chemical Instinct felt a jolt of arousal run through her like never before.

"Please fuck your pathetic pony, Daddy, please fuck her. Pleasepleasepleaseplease fuck your pony's holes, they belong to you. These pony's holes are all yours Daddy, so please fuck them with your long, thick, throbbing cock!"

With no warning, Chemical's pussy was filled with her dominant's cock. She choked, and the hand on her neck squeezed slightly. Mistress Kamehameha was big. Extremely big. Ten inches big. Even with how wet she was, the fit was incredibly tight. It wasn't helped by how Chemical's pussy kept clamping down on Daddy's cock, which true to her description, throbbed every time she did so.

"You know princess, you didn't finish counting, earlier. I'll be nice and tell you where you left off. You were at fourteen, pony. I'll offer you a deal. You can either get spanked 16 more times while I fuck you, and you can't cum, or I'll spank your pussy five times in a row right now and you can cum as soon as I deliver the last strike. Choose, princess." The idea of not cumming through another 16 strikes sounded like utter torture. Chemical knew the five slaps to her pussy were going to be brutal, but… Her choice was already made.

"The second one, Daddy." Mistress bit into her shoulder, hard, and she squealed. She let Chemical go, laughing.

"Adorable. Alright princess, I'll give you what you need, and you can cum at the end, as agreed." Chemical felt arms wrap around her midsection, and she was pulled up and off the bed, Mistress' cock still lodged deep in her. Mistress pulled Chemical into her lap, forcing her all the way back down on her cock in the process, as deep as it could possibly go.

Mistress drew her right hand back, and Chemical found it was much harder not to tense up when she could see the spanking ahead of the impact. Her legs were then spread by Mistress, who trapped Chemical's feet with her own then pulled them open, exposing where they were joined together to punishment.

"Count as I strike you, princess or no cumming, and I know you won't be able to hold back after five, so it's either count or disobey me two times in a row, is that clear?" Chemical nodded fervently.

"Yes, Daddy."

Crack "O-one!" By the time Chemical was in the middle of calling out the first hit, Mistress' hand was already on its way back down towards her pussy for the second strike. Chemical had to devote all her mental power to not fully losing herself to the sensation of her clit being struck. Her mind felt like static.

Smack! "Twooo!" The pain and the pleasure were both unimaginable. Her most sensitive parts were being viciously spanked and with every consecutive blow, she

Whap! "Thuhreee!" This one came out as essentially just a yelp that she managed to shape into a word. Goddesses, she was already close…

Thwap! "Fourrr!" Just one more, she could do it, hold it, hold it for one more second.

Crack! "FFFFiiiiivvvvveeeeee!" This last hit was focused squarely on her clit and Chemical came instantly. The orgasm crashed into her, and her muscles spasmed. She wriggled and writhed, though Mistress' held her in such a way that she barely was able to do much but vibrate in place, other than arching her back and pushing harder against the breasts of her Mistress.

"Good girl, very good girl, princess. My princess is so well-behaved, isn't she?" Mistress was practically purring into her ear now. "Now that we've gotten your punishment out of the way, I can really let loose, sweet mare. Goddesses, I love being inside this tight pussy of yours." Mistress bucked her hips. Chemical moaned. Mistress put her mouth back next to one of Instinct's ears. "Mmm… I want you to be nice and vocal with me, sweet pony. My princess should use her words while I'm fucking her, so I know exactly how she's feeling." She started slowly sawing her cock in and out of Chemical, letting the tip catch at her entrance as though she was about to pull out before beginning the push back in.

"Yes, Daddy…oohhh… your p-pony will let you tell you how you're making her feel. Right now D-Daddy is making her feel so, so good. Oh, Goddesses, please fuck your pony Daddy, she's desperate for it!" Mistress growled at her words.

"Then take it!" Chemical was suddenly being shifted in place, Mistress reaching under her legs to fold her into a full nelson. She stood up off the bed and began slamming her length into Chemical's dripping pussy with as much force as she could. The thrusts were fast and hard and Instinct's pussy clenched firmly around her Mistress' length but didn't seem to slow her at all. Instinct moaned, the heat in her belly washing over her in waves. The pleasure of her Mistress' velvet soft skin over the iron of her cock pressing against her walls was everything.

"Yes, thank you Daddy! Your pony loves this Daddy, she loves it so much." She let out a sob of relief. She didn't realize how much she'd been craving something inside her. She fit snugly against her Mistress, her head tucked under her chin. Mistress was fucking her so good. In. Out. In. Out. Chemical let out a sob. Her whole world narrowed down to her center and Mistress' length. It dominated her mind. The pleasure was all-consuming. She could feel Mistress' love for her; she had to make sure Mistress' knew how much she loved her too.

"Love you, Daddy. Love you love you love you! Oh fuck Daddy!" Mistress growled and suddenly Chemical's clit was being pinched and her world went white. Her eyes rolled back in her head but her vision stayed fully white. She couldn't comprehend the pleasure she was feeling. Her body was no longer her own. She was an instrument, played by a virtuoso. It was the only thing that made sense. This pony belonged to Mistress. These thoughts played in a loop while her climax wrecked her. She was vaguely aware that she was being moved, though her core remained tightly filled all throughout.

Finally, she came back to herself. She was on the bed once more. She was on her knees, face down again, though this time there was a pillow cushioning her head, and one under her stomach as well. She sighed happily, Mistress took such good care of her. She hardly deserved— wait, no. It wasn't for ponies like Chemical to decide what they deserved. That was Mistress' role, and Chemical wanted to be good for Mistress always, even in her head.

Mistress was draped completely over her, covering Instinct's entire body with her frame. She was moving rhythmically, her thrusts deep but slow, only pulling out a few inches before moving back in. Chemical wanted to make sure this was pleasurable for her Mistress, so she began clenching in time with the thrusts, and Mistress gave a light growl in response.

"I see you're back with me again, princess. Good girl, tightening up like that." She pulled back just enough to give herself room to nip Chemical's left ear, growling softly as she did so. "I can tell you're reaching your limits, babygirl, so we're finishing up soon. I don't wanna hear any objections, I know your body's signs well enough. Be a good girl, and once we both finish, let me take care of you, or I'll be disappointed."

"Yes, Daddy. This body is Daddy's to do with as she pleases." That got Mistress growling again, and a shiver ran down Chemical's back. Goddesses, she loved it when Mistress turned into the predator she was on the racetrack. Chemical was happy to be her prey. The force of Mistress' thrusts increased, but she kept to her slow withdrawals from her mare. With it came an ever so slight change in angle that was pressing her length against Chemical's front wall. It was building her up quickly again, but she could also tell from the pulsing of her Mistress' cock that the end was close for both of them.

"Yes yes yes yes, please Daddy. Give your pony all of your cum. Fill her up Daddy, breed her, please!"

"Fuck, princess, I'll give you exactly what you deserve." She began pulling further out with each thrust, and the pace increased slightly. Her Mistress wanted to draw this out, Chemical could tell. She moaned again, a loud keening sound. She could no longer maintain her own rhythmic clenching, the pleasure building up causing her to begin fluttering her walls around mistress cock at random intervals. After roughly another minute or so, Mistress groaned and gave a final, extra forceful thrust, pushing as deep as she could go.

The cum was warm, so warm as it filled Chemical up. Another orgasm washed over her, this time making her feel more present in her body. The pleasure was gentle, and she understand even as it blanketed her that this was Mistress' goal all along. She wanted to make sure Chemical would be awake to enjoy the sensation of them finishing together. Her love for Mistress filled her mind, and she giggled even as the climax continued washing over her while Mistress continued to fill her womb. Her hand went to her belly, and she rubbed it with reverence.

Her peak subsided, leaving only the warmth of Mistress' seed within her, and instantly, drowsiness set in. Oh. Mistress was right. She really was at her limit. A yawn bubbled up, and though she tried to fight it, it forced itself out. Her back arched as the yawn temporarily took over her body. Mistress' arms snaked around her midsection.

"Very good, princess. I can tell how tired you are. Let yourself rest. We'll clean up and take care of each other when you wake. I love you, sweetheart." Her eyes began to droop. That sounded nice.

"Mmm…yes, Daddy. Love you…too." She yawned again, and let her eyes fully close. Mistress rolled them over, and Chemical felt her weight come to rest atop her lover again. King Kamehameha placed a gentle kiss to Chemical Instinct's crown, and the mare drifted off, safe and sound in the arms of her stallion.
