Senior Year Ponies Up

Sunset was pretty sure that even without her own baleful influence on Canterlot High, Ms. Redheart, the school nurse, would have seen some shit. As it was, she acted like someone who'd seen centuries of it. It was easy to forget she wasn't very old herself. She'd arrived during Sunset's own time at the school, immediately after finishing her degree. Sunset wasn't actually sure which of them was older, chronologically, though of course Ms. Redheart had no idea of Sunset's real age.

Now, she swiveled on her stool and turned to face the three girls standing (well, Pinkie was lying on the cot) before her.

"Muffins, I will never believe your 'magical centaur in the woods' story," she said. Muffins just blushed and self-consciously rubbed her still-swollen belly.

"Sunset, are you sure you don't have anything to add?" Sunset shook her head. "Pinkie?" Pinkie mimed zipping her lips. Redheart sighed.

"Well, all right. Muffins, whatever this is and wherever it came from, I can't imagine it can get you pregnant."

"You know that much about how different kinds of sperm look under a microscope?" Sunset wasn't an expert, of course, but it seemed like pretty esoteric knowledge.

"Not normally," Redheart shrugged, "I was going to try to look it up on the Internet. Well, that, and honestly your story's so weird, I half expected it to be milk or something. But, well, take a look." She stood and walked over to the medicine cabinet, in which she began rummaging. Sunlight replaced her on the stool and peered into the microscope's eyepiece. She'd seen photos of sperm in passing, and dimly remembered tadpole-looking things with the general translucency of cells under a microscope. The things revealed by the microscope had the same general head-and-tail setup, but the heads were heart-shaped and pinkish, while the tails were undulating, glowing rainbows. Sunset blushed.

"Wow," she said. "That sure is something."

"I don't know whether to call the F.B.I. and ask for Agent Mulder, or write one of you a glowing recommendation letter to a microbiology program. I'll probably compromise by trying to forget this whole thing." She pulled out two bottles of pills and stood. "Muffins, I can give you some Plan B if you want, that's the 'morning after pill', but it'll make you nauseous and if those things can get you pregnant, medical science has nothing to do with it anyway. But up to you." Muffins thought a bit, then shook her head. Redheart put the first bottle back down. "Okay, well, if you squat and spread your legs over the toilet, enough of that stuff should drain out that it won't be visible. You can do it here if you're afraid to go home like that." She walked over to Pinkie. "Pinkie, you know I respect your personal choices, but I thought you learned this one already. If you want to sleep with ten guys at once that's your business, but you can't swallow all their semen! There's such a thing as too much!"

"I know," Pinkie moaned, "but it was just one load this time! I thought it'd be okay. It was just...such a big load..."

Redheart sighed. "I suppose I won't get very far telling you that the human testes just cannot contain this much fluid?"

Pinkie said nothing.

Redheart sighed again. "All right. Well, I've got some medicine here that will settle your stomach. If you needed to vomit you'd have done so already, so you don't need to go to the hospital. But next time you see fit to fellate a," and here she actually made the air quotes, "'magical forest centaur', please don't swallow." Pinkie nodded. Redheart gave her a pill and a cup of water.

"Sunset," she said, "a word?"

Filled with dread, Sunset followed her from the sick room into the waiting room that housed the reception desk. Since it was after-hours, the receptionist had already gone home, and the privacy soundproofing kept Pinkie or Muffins from overhearing anything.

"Sunset," Redheart said, "I appreciate that you've turned over a new leaf, I really do. But the only things I've ever heard of that looked like those sperm, or whatever they were, involved you. Now please, I want to make sure I give these girls the best care I can. Is there anything you can tell me about this? I promise, my only concern is for the health of the students, I won't tell anyone. I suspect if you do know anything, no one would believe me anyway."

"Well," Sunset took a deep breath, and told her the whole story. It took some time.

"I know it doesn't sound much better than the forest centaur," Sunset finished, "but it's true." She remembered the contents of her backpack, and rummaged around for a bit before pulling out one of the blue-papered vials. "See? Here's one of the potions. You can look at the label. It's printed, but it's in Equestrian. I know it's not proof, but I don't really want to show you. It makes you really horny."

She handed over the bottle, and Redheart looked it over. She gave a low whistle.

"I would have believed you anyway," she said. "I hear what the students say, and you've really impressed everyone with your new attitude. I know you wouldn't lie to me about something important to health. But seeing an alien language on a magic potion...it's something else. Thank you for trusting me." She smiled, and moved to hand the potion back.

Sunset smiled and let out a deep breath, but didn't take it. "Thanks for understanding. You can have it if you want, since you think it's interesting. I've got plenty, and can always get more."

Redheart thought for a bit, then put it in her bag.

"Thanks. I can't imagine I'll want to use it, but you're right, it's fascinating." She cleared her throat and looked serious. "Now, as your nurse, I do have to remind you that even if you can't get anybody pregnant, you should still be careful of sexually transmitted infections. You should really use a condom."

Sunset blushed. "I ah, asked Twilight about that in a letter. Apparently all the potions have magic against that, too."

Redheart let out a whistle. "That's quite the feat. If you can ever figure out how to make these over here, you'd save lives. And make a fortune."

"I'll let Apple Bloom know," Sunset said. "The other Apple Bloom, that is. Anyway, are they going to be okay?"

"They should be fine," Redheart said. "Pinkie's seen worse. That girl just loves being accommodating. And Muffins was just worried. I'll make sure to take care of them. I'm sure they'll want to see you later, but maybe let them rest for now. I know you've been intimate, but sometimes people still would rather not be seen when they're not at their best."

Sunset nodded, and left.

Redheart sat down heavily on the receptionist's chair with a sigh. She needed a moment to collect herself. She took it, then headed back to the sick room to see if the two overstuffed girls needed anything else.

Unbeknownst to her or Sunset, Twilight Sparkle wasn't the only one to realize her security was, well, the security of a high school nurse. From her distant apartment, Adiago Dazzle had been watching and listening to the whole conversation. When Redheart returned to the sick room, she took off her headset and grinned.

"Aria," she called across the hall, "I've just made a wonderful discovery..."

"Sunset Shimmer!" Sunset thought she was done for the day, but Trixie's voice made her stop and sigh. Much though she was ready to just go home, she knew ignoring the bossy girl would not improve the situation. She turned.

"Yes, Trixie?" She didn't bother to keep the fatigue from her voice.

The hallway was dark, with only the emergency lights on. The visit to the nurse had gone so long, Sunset thought they must be the only ones left in the school. She could barely see more than Trixie's silhouette, though the other girl was less than twenty feet away and advancing.

"Trixie saw you pleasuring Pinkie and Muffins in the locker room," Trixie said, and Sunset's eyes widened. "Trixie is horny. You will service her as well."

Sunset nearly choked.

"What? No."

Trixie tossed aside her shirt. She was close enough to see better now. Her breasts were nice - moderately sized over a toned stomach. Still, Sunset felt no stirrings.

"How can you refuse the fit and sexy Trixie's glorious feminine charms? Especially for the inferior Pinkie Pie? Why, the whole school has enjoyed her! To lie with Trixie is a rare treat!"

"Yeah, pass," Sunset began to walk away.

"Do not walk away from the glorious and sensuous Trixie! Such an opportunity may never come again!"

"I hope I'll be so lucky," Sunset said, then shrugged, and stopped for just a moment. "Look Trixie, I know you won't listen to me now, but just in case you do someday: you look good. I'm sure someone would be happy to enjoy your 'glorious feminine charms'. But I'm having enough trouble with how horny this magic makes me. I don't want anyone who assumes I'm theirs for the taking. Ask someone else if they're interested, and they probably will be."

"Hah! You don't know what you're missing out on, Shimmer! You can't handle Trixie!"

Sunset sighed. "I'm sure," she said, and left.

Trixie yelled after her for a bit, then put her shirt back on with a flounce. Frustrated and desperately horny, she returned to the locker room. Trixie knew the janitors wouldn't be in until eight, and the whole place still smelled overwhelmingly of sex, with several pools of fragrant cum still puddled on the floor. It reminded Trixie of stealthily watching the whole thing from hiding, and she reached under her panties to her soaking pussy. She looked over at the lockers where she remembered Sunset pressing Muffins, plunging that thick animal cock into her willing body. She stroked herself harder and harder imagining it, then pulled of her panties entirely. Imagining Sunset's cock, she worked three fingers into herself and moved them in a frenzy, tweaking her clit with her thumb as she did so. Before long, she nearly fell over as her knees weakened in an intense orgasm.

As she gathered her thoughts, she found herself still staring at the lockers. Lockers...

Sunset will pay for turning Trixie down, she thought. The nerve!

Using practiced skills and her trusty set of assorted pins and screwdrivers, she forced the lock on Sunset's locker. She wasn't sure what she intended to do exactly - perhaps leave her bra or panties as a taunt. But when she pulled the door open, she saw the crate full of bottles, and stopped. She'd heard Sunset mention a potion. Maybe this was it? She picked up a blue labeled bottle, but everything on the label was incomprehensible. Was that a picture of a horse? She rummaged a bit more, and found more bottles, labeled in yellow, equally incomprehensible.

She began to put them back, but the blue label came off in her hand. For some reason it wasn't glued to the bottle, just fitted snugly around it. As a result, it was easy to remove.

Maybe one gives you the dick, and the other gives it to your partner, Trixie thought, grinning. Won't Sunset be surprised next time she wants to fuck some harlot, and ends up fucked herself? Quickly, she set about switching the labels. As an afterthought, she took one bottle of each for herself.

With all her recent distractions, Sunset nearly made a critical error. Luckily for her, she had friends, and electronics.

Not long after she arrived home, her phone beeped twice in quick succession.

The first was a calendar reminder: Pack for Biology Trip Tomorrow.

The second was a pair of snapchats from Rarity. The first was a selfie of her alabaster friend in a truly stunning black corset, panties, and garters, her full breasts proudly free above the dark cloth, nipples stiff. The caption read: Have a good trip, darling. The second was another selfie, this one showing her from behind, bent over her bed, in the same outfit. It left no doubt that the panties were open-crotch and that Rarity was dripping. The caption: You'll have some more biology work waiting when you get back.

She sent back that she'd be using the last potion she had on her just based on the photos, then did so.

After, she packed for the trip. Unlike her friends, Sunset had elected to take an ecology elective. Unfortunately, Canterlot's urbanization in this world meant there weren't any good places to do a real ecological study nearby - even the woods the cross country team ran in weren't large enough to have any chance of finding signs of any large animals. So they were taking a few days off class to go out to the mountains to do field work in what could pass for real wilderness. It was only a few days, but still, she was sad to be leaving when she'd just discovered her sexual preference - and how many of her friends were enthusiastic about it.

In deference to that, she made sure to drop by the locker room before the bus left the next day. She wasn't sure what kind of privacy she might or might not have, but she expected to miss her friends, and that she might want to think of them fondly if she got any. It couldn't hurt to be prepared.

To her surprise, Rainbow Dash was waiting when she got there. At first she thought she might be hoping for a quickie, but not even Dash could be that fast - for those staying, the first period bell was about to ring.

"Uh, hey," Dash said, scratching the back of her head, "I uh, was kinda curious what it felt like. You know, having one. Can I have a few of those potions before you go?"

Sunset shrugged. "Sure." She handed Dash a few more bottles as she stocked her own bag. Then the bell rang, and both girls rushed off. Neither knew the blue-labeled bottles had once been labeled in yellow.

Sunset wasn't really close with any of the other students on the ecology trip. She'd taken it out of genuine interest. Equestria had almost no equivalent concept of ecological science: all of the environments there were either completely controlled by ponies, or dangerously and magically unstable. She had an idle fantasy that, if she were ever willing and able to return to Equestria, ecological science might help solve the mysteries of the Everfree. And even if not, it was nice to take a class that wasn't basically review from her time at the School for Gifted Unicorns.

Unfortunately, deserved or not, ecology had a reputation as being easier or softer than the other senior science electives, so most of the rest of the class were underachievers. Of the other motivated students, they were mostly those focused on social sciences, or hippies like Tree Hugger who mostly wanted to learn about pollution and environmentalism.

Initially, Sunset would have assumed Sonata Dusk fell in the "underachiever" category. They were far enough into the semester, though, that she knew the other girl did surprisingly well in the class, given her reputation. It was also the only class she didn't share with the other former sirens, though Sunset had never figured out how to ask exactly why that was.

Indeed, while Sonata was friendly to her in the class, the other two Dazzlings remained cold, and this cold shoulder prevented Sunset from being confident enough in the possibility of reconciliation to ask Sonata about it. But she showed up for the trip like everyone else, though she didn't look happy about it.

The bus ride took several hours, and there wasn't much on the docket for the first day other than settling in. By the time they'd finished unpacking their things and getting the tour, it was dinner time.

They were staying at an old summer camp, with all that entailed. The lodgings were bunk beds in two communal cabins, one for the boys, one for the girls. Groups from other schools stayed in the rest. In deference both to the age of the students and the comfort of the teachers, the staff were staying in the main house with the dining room, but in-cabin at sundown and lights out at 10pm would be strictly enforced by venue staff.

There was significant grumbling about it, but Sunset didn't mind. The cabins had their own bathrooms and showers, which meant she could find privacy if she wanted it. Other than that, she was just glad to have some time free of other homework. Her enthusiasm dimmed a little when she discovered there was no cell phone service or Internet, but she took heart in the fact that she'd thought to download Rarity's pictures from the night before.

After dinner, they were allowed to go to the lake until sundown. Sunset enjoyed swimming around, but avoided checking out the other students in their swimsuits too much. Though she suspected the presence of her fellow Rainbooms was required to provoke her spontaneous cock, it seemed better safe than sorry.

When they returned to the cabin at sundown, she discovered several of her fellow girls had been more excited about the prospect. Flitter and Cloudchaser were both drooling over the boys from Crystal Prep, and they collaborated with Tree Hugger, who wanted to see her boyfriend in the boys' cabin, on an elaborate escape plan. Sunset just rolled her eyes and got ready for bed.

Their mission seemed to go well. The three crept out the door not long after lights out, and didn't seem to get caught. To everyone's complete lack of surprise, Lyra slipped out of her own bunk and joined Bon Bon not long after. Then everything was quiet, and soon the rhythmic breathing of sleep filled the cabin.

Sunset was still wide awake. A night owl on her own time, she was also distracted by the thought of Rarity's photos sitting on her phone. Mostly out of paranoia, she wanted to wait until she was sure everyone else was asleep before going to the bathroom to take care of herself, though. Just as she thought everything sounded peaceful, and was getting ready to move, a voice whispered her name in her ear, from the floor.

Her eyes shot open and she turned her head. It had been dark enough that her eyes had adjusted well enough to make out Sonata's pretty face right in front of her.

"Wha..." Sunset spoke as quietly as she possibly could.

"Something's wrong," Sonata whispered back, equally quiet. "I need to talk to you. Can you move over?"

Sunset wasn't entirely enthusiastic about sharing a bed with Sonata, but it was impossible to mistake the worry in the other girl's voice, and she'd never been a good liar even with evil magic helping her. And given the context of the cabin, there didn't seem to be a better option. She slid over towards the window, and gestured Sonata up.

The bed was tiny, and Sonata slid in close in the interests of being quiet. They weren't quite touching, but as they faced each other, their lips nearly did.

"Um, it's about the other sirens," Sonata said. Sunset nodded.

"So, well, you know we never got on great, even in the old days. We all had to be mean, then, to eat, but they liked it more. Aria even liked being mean to me, and Adagio never stopped her. When we didn't have to be mean anymore, I thought they'd get better, like I hear you did. But they never really did."

Sunset wasn't sure why this was coming up now, but it was clear Sonata was distressed. "You don't need to care what they do, you know. You don't have to be with them any more."

"I know," Sonata whispered back, "but we've been together so long. They're the only creatures I've ever been close to. I can't leave them now."

Sunset wasn't sure what to say. She wanted to help Sonata, but it seemed unlikely she'd be able to get through centuries of codependency in a whispered conversation in a camp bunk. Instead she took Sonata's hand in what she hoped was a comforting fashion, hoping to encourage her to explain why the matter had come to a head now.

"It seemed like they weren't doing any harm, either," she went on, "so I figured maybe they'd get better. But yesterday, I overheard Adagio talking about some new information. Something about you. She stopped talking as soon as I came up the stairs. I asked her if I'd just heard your name, but she said not to worry about it."

"That doesn't sound great," Sunset agreed. "Do you know anything else?"

"No," Sonata said, "but the only reason she'd hide it from me is if she wanted to hide it from you. And they're not into surprise parties."

Sunset sighed. "You're right. Thanks, Sonata. I wish we had cell service her so I could warn my friends. But thanks for letting me know." She gave Sonata's hand an encouraging squeeze. She went to let go, expecting the other girl to leave, but Sonata gripped her hand back, gently but firmly.

"It's okay," she whispered. "I like you better than them anyway. But...I'm scared. If they find out, they'll hurt me."

"We won't let them," Sunset said. "That's not how friends should treat each other."

"I don't think anyone told them that."

"We will, if we have to." Sunset gripped her hand back, firmly.

Sonata pressed forward, lowering her head and snuggling it into Sunset's bosom. "Thanks," she said, voice quavering. She trembled slightly.

"Sonata...have they hurt you before?" Sunset dreaded the answer, but she had to know.

"Not since we lost our powers."

"So not since it's stopped being easy?" Sunset couldn't keep a bit of anger out of her voice. Sonata just nodded.

"I'll make sure it's never easy again."

Sonata just shook a little, and buried her head closer.

Sunset had no interest in dislodging the clearly miserable creature, but at the same time she was aware that nothing but a thin shirt separated Sonata's face from her breasts. Still, she wrapped her hands slightly awkwardly around the siren and patted her, she hoped comfortingly.

Sonata gradually pressed closer, until Sunset had her in a full embrace. She couldn't help but be aware of Sonata's body pressed against her. The siren's firm breasts pressed against her own, and her body heat was delicious in the slightly cold night. Sunset rested her chin on the other girl's head and tried not to think about it, with mixed success.

She nearly cried out in surprise when Sonata's hand ran gently across her panty-clad rear.

"Sonata, what...?"

Sonata looked up at her, magenta eyes wide.

"What's wrong?"

"Why did you touch me like that?"

"You wanted me to."

"What? I didn't say that."

"Oh, sorry," she withdrew her hand. "I...we still have a tiny bit of magic, you know." Sunset couldn't help but tense up. "Not like that! Only senses. But I can still hear it when someone wants me. I guess we were just talking so softly, I thought you'd said it out loud. Sorry."

"It's okay," Sunset said. There was a long pause.

"I touched you like that because I think you're hot, too," Sonata finally said. "Can I do it again?"

"It's...complicated," Sunset said. "I like girls, but I don't like having sex as a girl. I have a potion from Equestria I use. It gives me a penis. If you're into girls, I don't think we're really compatible."

"I'm a siren," Sonata said. "I don't really care about gender." Slowly she moved her hand down Sunset's back, giving her plenty of time to say no.

Sunset felt on some level like she should. Sonata was her former enemy. She admitted she still had a little magic. She was vulnerable, hurt. Maybe she didn't know what she wanted.

Sonata's hand reached Sunset's ass, and slipped beneath her panties.

Okay, she knew what she wanted.

Sunset said nothing. To her surprise, her own hand seemed to have moved down Sonata's back, and was now resting on the other girl's ass. She wasn't wearing panties in the first place.

Sonata stroked Sunset's rump gently, sending shivers up her spine at the light touch, then gripped one cheek firmly. Sonata shivered, and suppressed a giggle.

"Oh wow," she murmured. Before Sunset could ask what she meant, she moved both hands up and began lifting off Sunset's shirt.

Sunset realized it was the point of no return, at least for some kind of fooling around. Some part of her still wanted to tell Sonata to stop.

Instead, she reached her own hands down, and began pulling up the siren's own shirt.

Two garments fell soundlessly to the wooden floor. Two pairs of firm breasts fell free, warm flesh rubbing deliciously on warm flesh, hard nipples caressing each other. Sunset reached her hand down to touch Sonata's rear again. It was full and muscular, firm to the touch but soft and smooth. As her hand trailed to the bottom, Sonata spread her legs slightly, and Sunset cupped her hand between them, feeling the tips of her nether lips and a slight moisture. Sonata parted her lips and took a quick breath. Her own hand stole down and pressed between Sunset's panties and her thigh, pushing them down. Sunset pressed her rear back and folded her legs up, letting Sonata pull them off.

As she did, Sunset's pony cock sprang forth, firm and ready.

"Wow," Sonata breathed. "I thought you needed a potion."

"I did too," Sunset said.

"It's like one back home," Sonata breathed as she gently stroked it, making Sunset's vision swim with pleasure.

"Yeah, the potion knows I'm Equestrian, so it gives me an Equestrian dick."

"I love it," Sonata breathed. She traced her fingers up and down along the shaft, making Sunset shiver.

Sunset brought her other hand around and pressed it to Sonata's breast, lightly squeezing the satisfyingly yielding flesh. She traced the base and sides, running her fingers across the bones, then brought a pant to Sonata by circling in along the surface, closer and closer to the nipple, before finally touching it softly.

In reply, Sonata lowered her head further, taking one of Sunset's nipples into her mouth. She ran her tongue along and around it, then gently took it in her teeth. As she did, she pressed her rear back, spreading her legs further. Sunset ran her hand gently over Sonata's mound (lightly furred), and along her thighs, until Sonata spread her legs even wider, and pressed her clit against Sunset's teasing hand.

From across the room, a bunk creaked. They froze, reminded of the girls sleeping all around them.

"Mmmmmbest....friends..." Lyra muttered in her sleep.

After a moment, Sonata began working her lips on Sunset's nipple again. Her hand still stroked Sunset's cock, and she ran it gently from the brimming balls all the way to the tip. Then she reached down and grasped it, pulling it forward as she began moving her own legs forward. Sunset managed to pull herself together.

"I should take a potion, just to be safe," she whispered. "They have some extra magic. Outside pocket of my bag." She didn't really think Sonata had any diseases, but she was a siren. One never knew.

Sonata reached down off the side of the bunk and produced a potion. Sunset chugged it eagerly. The warmth flowed through her, but it felt different somehow. Poised, or anticipatory, even more than usual. She shrugged it off as an effect of the foreplay.

"Are you sure?" Sunset asked, taking advantage of her momentary self-control.

Sonata just looked puzzled. "Of course. Why wouldn't I be?"

"I dunno," Sunset flailed. "It's just...we haven't ever really been close. My friends and I cost you your special magic gem..."

"You said you'd help me," Sonata said. "No one ever said that. It's nice. And I don't mind losing the gem. Sure, we were powerful, but the others like that. I like just being me. And," she pressed her legs forward, her pussy lips stroking Sunset's cock-head, "I will really like being me with you inside me."

"I don't know how I'll stay quiet," Sunset murmured, already nearly moaning from the feeling of Sonata's wet opening on her cock.

"I have an idea," Sonata said, and kissed her.

Sunset was so surprised by the kiss, it took her a moment to process that Sonata had started pushing her hips down, sinking Sunset's pony cock into her azure pussy. She decided to kiss back, and thrust her hips back, and soon the two were locked together, Sunset hilted in Sonata's snug sex.

Slowly, carefully, Sunset turned, lifting herself and pushing Sonata down until the latter lay underneath her on the bunk. She managed to avoid a significant creak. Paranoid, the two stopped dead for a moment, Sunset still fully sheathed in Sonata, straining to hear if anyone had been disturbed.

No sound came from the surrounding bunks. Slowly, carefully, Sunset began plunging in and out of Sonata, lips still locked together to muffle moans. She pressed her chest tightly to Sonata's, relishing the contact of their breasts.

Steadily she fucked, slowly pulling nearly out of her lover before plunging all the way back in. Sonata took her shaft gladly, lips trembling along with her body, more and more frequently as her orgasm approached. Sunset could tell hers was coming, too. It seemed like Sonata might come later, so she tried to pull further out and modulate her strokes, only for Sonata to lock her legs around her, holding her in. She tried to break the kiss to warn the siren, but Sonata sucked hungrily at her mouth and pressed one hand to her back and the other to the back of her head, holding her as close as possible.

Sunset gave in. Her flare sealed Sonata tight, and she lost herself in orgasm.

Sonata was close. She felt Sunset's cock pulsing inside her, felt the pressure build in her pussy as the seed swelled it. Then, with a tiny twinge, the first surge of cum passed into her deepest reaches, where the last remnants of her magic still lived. And those remnants recognized Equestrian magic at long last. The raw power flooded into her as joy, and a blinding, heedless orgasm took her. She grasped Sunset as close as possible, craving as much seed as she could get inside her.

As Sonata's orgasm began, Sunset felt it all across her body, not only in the pussy walls milking her cock, but as a tingle of energy across their embracing breasts, through their dancing tongues, and along Sonata's thighs and legs grasping her. Her own orgasm redoubled, and she began emptying her balls in massive waves into the siren.

And, deep in Sonata's body, where she was very much still a siren, Sunset's very-much-still-pony sperm, enchanted for just such a purpose, found a body that, unlike Muffins, was waiting for heart-shaped, rainbow-tailed sperm. And, true to that purpose, the magic brought Sonata Dusk into prime breeding season.

Just as Sunset Shimmer pumped her orgasm-quaking belly plump with fertile seed.

Unaware of any of this, Sunset and Sonata rode out their orgasms. Sunset, barely coming to herself in time, grabbed her shirt off the floor and stuffed it between Sonata's legs as her orgasm faded, protecting the bunk bed from her overflowing sperm. When both had recovered, Sonata went to the bathroom and cleaned up as best she could. Sunset was surprised when rather than returning to her own bunk, she came back.

"Can I sleep with you?" Sonata asked, "I'll feel safer."

Sunset looked over at Lyra and Bon Bon, seemingly intent on bunking together all night.

"Sure," she said.
