Words: 4763 ****** Depraving the Heroines ****** by AnneMarkus Summary A shameless copy/homage to Depraving the Huntresses, in a way. Lots of monster girls getting each other off, too. ***** Beginnings ***** Ochako's eyes fluttered open, and she stared up at the hospital room's ceiling. She immediately noticed the smell of fish; but it wasn't nearly as bad as you'd think. In fact, it was quite pleasant. She tried to move her head around, but she instantly felt as sick as if she'd used her quirk on an elephant. She lay her head back, trying her best not to vomit. Luckily, her shuffling about managed to call the attention of her friend in the room. Tsuyu's wide eyes appeared over the gravity girl. "You're awake, ribbit. I was starting to worry" she did her best to smile, a gesture that few people but Ochako, who'd spent such a long time as her partner and thus knew her limited range of expressions, could truly appreciate. She gave back the best she could, which amounted to a small curling of the lips. "Wh-... What h-happened...?" Tsuyu sat by her on the hospital bed, taking her hand. "We were fighting a villain... We split up to look for him, and when we found you... You were shivering on the floor, ribbit. We didn't find any wounds, and the doctors found no poison... They gave you an intensive treatment, just in case. You never know what kind of quirk might pop up, ribbit." That explained why she couldn't move; who knew what so many meds could do to a body? She really did recall something about a mission... the details were hazy, but the anesthetics were starting to wear off. ... Ochako and Tsuyu, or rather, Uravity and Froppy, were following close behind their pro hero chaperone, Ryukyu. It was not their first patrol, but after everything that'd happened since the beginning of term, UA was definitely not willing to have two of its students doing hero work unsupervised. The three of them heard very clear cries for help coming from a nearby alley, and, as heroes do, jumped in to help. The guy looked about as average as it gets: black ski mask over the face, black sweater and brown pants with some not-so-expensive sneakers. When he saw the heroic trio, he darted off into a nearby building, which happened to be an empty warehouse. They all entered and decided to split off and... Well, Ochako's memory cut out at that point. According to Tsuyu, after they arrested the guy she was just... There, on the ground. Ochako blinked, returning to reality. Tsuyu's unmoving eyes stared back. It was hard not to notice how... Well, how cute she was. Even the more frog-like parts of her, like her tongue, accentuated the adorable face she had. The gravity hero forced her eyes closed, still not well enough to shake her head. What the hell?! She wasn't into girls, and the way she'd just looked at her best friend was not platonic. Even as she tried to force the memory away, she felt the blood rushing to her cheeks. Too tempted at one more glance, she opened her eyes, but found only the white of the room. "T-Tsuyu-chan...?!" "Still here, ribbit. Just call me if you need me." The usually bubbly girl let a sigh escape her lips, not sure if it was one of relief or frustration. Deciding that she had no other option other than stay awake and torture herself over her newfound attraction, she closed her eyes and drifted off to sleep. Her dreams proved worse than reality. ... The two girls huffed and panted, their training finally done for the day. All of the other girls were absent today, preferring to study with Yaoyorozu for an upcoming test. Alone in the dressing room, Ochako took off her UA standard issue suit, still a bit sticky from Tsuyu's occasional tongue lashings. Suddenly, she felt a set of slightly cold arms wrap around her semi-nude body. "Occhan... I'm really hot, Occhan..." The familiar voice send shivers down her back, but in a pleasant way. She was confused, but her body betrayed her as it gripped the frog girl back, turning around. The wide eyes she knew well wore a lusty look as Tsuyu slowly started kissing Ochako's lips, inching ever closer to her mouth. No longer in control of her own actions, Uraraka's hands slid down her friend's back, groping her remarkably toned ass through her plain white underwear. Closing her eyes, Asui planted soft kisses right on Ochako's lips. Not long after, a probing tongue tried to force its way into the brown-haired girl's mouth, which she accepted in her lust filled haze. The long, sticky tongue explored the new surroundings well, tangling with its new dance partner. Unable to control herself either, Tsuyu held Ochako close and shot her eager tongue down her lover's throat. Ochako's eyes shot open, surprised by the strange feeling. Quickly though, a blush crept to her cheeks and her gaze rolled upwards as she reveled in the new sensations, enjoying very much the feeling of having her throat filled like so. Unable to take it anymore, she pushed the froggy lady to the ground, pawing at her underwear. Soon she found the hardening shaft, wrapping her hand around Tsuyu's... Thick... Swelling... Cock...? What...?! Ochako woke with a start, her heart racing. The lights in the room were off, and she found it safe to move her head again. She saw Tsuyu slinked back on a comfy chair, sleeping beside her, still in her tight hero outfit. She probably hadn't yet left her friend's side... Ochako blushed again, but returned to reality quickly. She took advantage of the skin-tight outfit to examine her friend's crotch. She couldn't be sure, of course, but it looked shaft free, hard or otherwise. She breathed the same sigh from earlier, unsure how to feel. Still staring at her friend, a hand floated down to between her own legs. After all that happened today, Ochako decided not to stop it, getting herself off to her best friend. Finishing quickly, she absentmindedly raised her fingers to her lips and sucked. It tasted... Sweet. Very sweet. It had the effect of warm milk, setting the bubbly girl to a drowsy state once more. She turned away as one final effort to get the frog girl out of her mind. Her next sleep was dreamless and Tsuyu free. A small part of her was disappointed. ***** First Changes ***** It'd been a week since she woke up in the hospital. By day three she could walk again, and by day five she was cleared to leave. It was a weekend, so she took the opportunity to stay a while with her parents, and today she'd be moving back into the dorm at UA. She liked her parents, but she appreciated air conditioning, too. Granted, she still didn't feel 100%. She felt like her reaction time had been severely nerfed, and more often than not her limbs felt like jelly. She hadn't told anyone this, but she also found herself unable to function without getting herself off at least once a day. Her thoughts invariably drifted back to her froggy friend, and she'd stopped fighting it a while ago. Whatever it was that awakened this in her, it probably wouldn't go away soon, and she still found guys hot, so she didn't have many complaints. Though she couldn't ever imagine the real Tsuyu in her fantasies, because she always... Packed something extra downstairs. When she wasn't in her daily fit of horniness, Ochako avoided any words related to sex at all costs. Her focus snapped back to the physical world as the train announced her stop coming up. From there it was a simple walk, or it would be if Ochako's legs didn't feel much more stable than jelly at the moment. Nevertheless, she fought her body's desire to collapse to the ground for long enough to reach school grounds. Barely having gotten to her familiar old room, she felt a familiar warmth getting to her. She usually only felt this at night though, right before sleep. Either the new location had somehow thrown her body out of whack, or things were getting worse... She hoped it was the former as she slid a hand down her cheap hand-me-down pants. Throwing herself onto her bed, she did her best not to make much sound, which she'd gotten quite good at with all the overnight stays at the hospital. Inserting her fingers onto herself, she arched back slightly and bit her lip. Was it just her or were these getting better and better? She brought her hand to her mouth to lick away at her sweet fluids. That was the only lasting change from whatever had knocked her out, it seemed. Even her saliva had been sweetening up lately, though it was obviously not as easy to notice. She went back to touching herself as her mind drifted to her first dream she had, back at the hospital. The thought of a tongue- deepthroating seemed as natural to her now as putting on shoes before leaving the house. Only about a million times hotter, of course. She realized her fantasies were a tad unrealistic, what with her not having to stop to breathe and all, but they still did their job. Soon enough she'd spent herself, panting on top of her bed. Classes wouldn't start in a while still, so she set an alarm clock and took off to dream world. She didn't notice as she slept, but her underwear started to tighten up ever so slightly. ... She felt very uncomfortable in her seat at the back of the class. Not because of the warm welcomes, that was still very nice. But because it was very hard to focus. With Tsuyu two seats ahead, even behind Iida's decently large frame, not to mention the other girls in class, it was increasingly hard not to slip her hands inside her underwear. All classes that day were in the classroom itself, which meant that at least they wouldn't be changing into their hero clothes; a small blessing, as the usually cheery girl feared how she would react around Tsuyu's skin tight suit and Yaoyorozu's unbelievably skimpy outfit. As Present Mic launched into his usual bombastic speech during english class, a sweet scent wafted over the class, though no one paid it much mind besides Ochako. It smelled exactly like her own fluids, and the wetness in her underwear told her exactly where it came from. Her body threatened to act on its own as she placed a hand on her thigh, inching ever so closer to its slick, needy objective. Enough was enough, Uraraka thought. If she wasn't paying attention to class anyway, she needed to take care of her ever rising libido. Barely having gone through the interaction of asking for the hall pass, the gravity hero slammed the door to the bathroom stall behind her before practically ripping off her clothes. What little sanity she held on to, she used to stuff her own sticky panties into her mouth, preventing herself from making too much noise as she plunged two fingers into her more than receiving folds, letting out a muffled, high pitched moan. Her other hand floated to her perky breasts, twisting and pinching at her nipples in ways she would never have dared to before. She jerked her hips, humping into her own hand and hoping to any god that might exist that no one hear her. Withdrawing her sweet fingers from herself, she rubbed her sensitive clit, her legs nearly buckling underneath her. She took a pause to realize that it was not only much more responsive, but also bigger. In fact, if she concentrated, she could see it growing before her very eyes! It was almost big enough that she could wrap her hand around it... And she was very tempted to. She calmed herself for a moment, sitting down on the toilet and spreading her legs, watching the nub reach upward as she absentmindedly continued to tweak her nipples. Slowly, she started to caress her new member, carefully grasping it. She gasped with a jolt of pleasure, noticing it was much softer than expected. Looking at it, she expected it to be just as hard as her classmate Kirishima, but it felt more like sponge cake: soft and malleable, yet also firm. Getting over the initial shock, she squeezed it tightly, pumping her hand upward and reveling in the feeling. She found the tip of it to be especially sensitive, bringing up her thumb to play with it, squirming over her own teasing. The shaft never showed signs of wanting to stop growing, and it started to thicken as well as lengthen. Soon enough, one hand was almost not enough to wrap around it, and its growth started to slow. Quickly inspecting the thing, Ochako determined it to be a good seven inches in length, and quite thick. With her focus out of the growing length, she noticed something else emerging. Right at the base of the new addition, two balls hastened to pop out, providing relief to a force Ochako didn't even realize she felt. The flood gates inside her lifted, and she transitioned from her slow, experimental stroking to openly and wildly thrusting into the provisional hole her hand formed. The underwear gag proved ineffective as her muffled moans made it well out of her small stall, but she hardly had the clear mind to care. Her eyes rolled back like usual as she reached her limit, gushing a thick, white liquid out of her recently formed cock. It fell back onto her stomach, and she eagerly scraped it to bring to her mouth, delighted to find it even sweeter than her female cum. She laid back on the toilet seat, taking in the situation. What. The. Hell. She was afraid to look again, but like or not, Ochako had a penis. A big one, if what she overheard the guys say was true. Panicking slightly, but still not looking, she brought her hand down, glad to find her girly slit still well and fine beneath her sack. Deciding that the changes might not be exclusive to her crotch, she slowly unlocked her stall and poked her head out, having already removed her makeshift gag. "...hello? Anyone?" Seemingly alone, she stepped out and looked at her own figure in the mirror, scanning every detail. What was once her clit had grown veiny, reddened skin around it, matched by her plump balls. Her hips looked wider, and turning around, her ass had definitely grown, but hopefully not enough to be noticed through her clothes. Even her breasts looked... Not quite bigger, but fuller. Like a pregnant woman, ready to feed her child... She couldn't be pregnant, could she? She looked thin as always, but... She decided that it was just too much to worry about for the moment. Scanning over herself one last time to make sure those were all the changes, she clothed herself once more. She just hoped that this situation didn't get any weirder. Three days later, it did. ***** Cinnamon ***** Ochako fell into routine quickly. She'd get off as soon as she woke up, then go to class. Depending on how much exposure she'd have to semi naked women in the changing room, she'd do it again either during lunch or after the final bell. She'd go out with friends and do what she was used to until one final session at night. She knew this was probably unhealthy, and she noticed that every time she came, the next time would feel even better. Additionally, she was starting to get a distaste for anything that wasn't mostly sugar. On the evening of the third day after she grew her new partner in crime, she caved. She was absolutely starving for some reason, but they weren't allowed to go out at that hour. Looking in the fridge of the dorm's common room, she found nothing worth eating, and in the cupboard were only a few salty crackers. Biting into one, she spat it out immediately. It tasted like dead fish bathed in toxic sludge. She almost resigned herself to a long, hungry night when an idea popped into her head. Taking the crackers up to her room, she made triple sure to lock the door. She stripped herself in a much familiar fashion, her jeans still tight from her recent growths, and watched with an involuntary grin as her friend rose to attention. Were she to look upon herself without whatever taint ran through her body, she would probably be horrified. Ah well. She grasped it gently, letting out a sigh of joy and relief. Sticky pre leaked out of her tip and she took it on her finger, licking it softly. Not as sweet as her cum, but it'd do. She stroked herself more, collecting her natural lubricant, and, once she had enough, spread it happily over hear meal. Testing it, she was delighted to find her own taste overrode the putrid snack's. Laying a few more on her bed, she got to work. By the time she was close to the edge, she had gone halfway through the package. She felt satisfied with her work already, but she couldn't resist the thought of something even sweeter. As she sprayed her load over the food, something in the back of her mind clicked, unbeknownst to her. She put two sticky crackers together in a sort of cum smore and bit into it. When she came to, she'd eaten the whole pack and blown two more loads. She looked proudly at the sticky strands between her fingers. Were they... Brown? Taste testing it once more, she threatened to black out again. The taste hit her like a truck, sickeningly sweet, with a slight spice to it. It tasted like hyper concentrated cinnamon. Getting up to clean herself off, she found a familiar sensation returning: her legs once again felt unsteady, but now she could describe it better. It felt exactly like her spongy shaft, like her legs were made of some sort of soft pastry. Sitting back down, she ran her eyes over her lower half... Only to find her shaft slowly turning the same brown as her seed. It spread, slow at first, then very quickly, already down to her knees and up to the base of her breasts. She noticed a warm sensation as she grew fuller, thicker, wherever her skin turned. Her thighs flared out, her belly gained some chub and her breasts grew a whole cup size. Alarmingly, the same syrupy cinnamon started to leak out of her nipples. The color spread to her hands and feet, already going up her neck as Ochako didn't make the slightest effort to stop it. Whatever it was, she knew this was who she was now. Her skin finally finished turning, spreading to her hair, adding sugary white streaks here and there, shared by her nipples, as well as her slick pussy and the tip of her hardening shaft. She grinned wickedly at her new tone of squishy, spongey skin. Then she groaned in pain. Unpleasant jolts flowed down her spine, as well as from her scalp. She felt her skeleton extending as a fluffy, white tail cropped from just above her wide butt. Her hair bulged out at two spots on the front, and suddenly two equally colored rabbit ears sprouted, easily making her a couple of inches taller. Bringing her hands to the sides of her head, she found her old ears missing. Her transformation completed with her front teeth growing out, making it hard to hide them without concentrating. She felt new energy as she stood up on her jiggly legs. Thoughts of how she would show her face in public were shoved away before she gave her own ass a light spank, feeling the whole thing wobble. The bunny girl giggled, not remotely worried about her new pastry flesh. She skipped around the room, not bothering to clothe herself. She was just too giddy at her new body. She seemed to be able to produce her syrupy sweet fluid at will by milking herself, which would help with her salty food problem. In fact, she couldn't wait to share her cummy treats with the rest of the class, especially the girls~ She got to work gathering it up into a bowl, absentmindedly humming. She didn't even notice when a certain frog girl knocked, concerned about the odd noises that were coming from the room. Nor did she notice when the same girl used the dorm's master key to walk in. ***** Tsuyu ***** Asui wasn't having the best of weeks. She visited her friend in the hospital at least once a day, which didn't help her studying for the upcoming midterms. Classes were getting even tougher as a whole, after so many villain attacks and with the fall of All Might. And even now that Ochako was back, she was quite distant, always locked up in her room. The noise complaints were what spurred her on to act. Something weird was going on, and she would get to the bottom of it today. After a good while trying to convince professor Aizawa to lend her the master key, she turned it on her classmate's door. Now, she hadn't been expecting something good, obviously, but no amount of preparation would have helped with what she saw. The first thing she noticed was the smell, like a freshly opened bakery, if said bakery used three times the amount of sugar in their cakes. Next she saw the puddles of... Brown. She couldn't quite describe it... It was like syrup, in a way, but more opaque and sticky. At last she saw the rabbit. Well, rabbit wasn't quite the right word. It was like a person with bunny-like features, much like she had her froggy quirk. Whoever it was had their back turned to Tsuyu, so it was hard to tell the gender, but the... Large behind suggested it was a girl. Her (?) arms were moving up and down in a quick rhythm, and she really was making these loud moans that sounded almost like they should be found in a porn video. Her skin was a slightly unnatural brown, but then again she had classes with a pink alien. Her bowl cut was familiar, at least if you removed the white specks... And now that she thought about it, the voice wasn't that strange either... "...Occhan...?" As the beast-person turned around, Tsuyu couldn't hold in her gasp. She was met with the same friendly smile she'd come to know along the year, the same slightly goofy expression. But something about it was wrong, like a speck of black in a white canvas. Even as she watched, she could swear that speck was growing and growing until that canvas was as dark as a new moon night. She made to step back, only to slip on what was once her friend's discarded underwear. Asui groaned, dazed from hitting her head on the wall. In the distance, she heard the click of a door being locked. Just as she was about to call out for help, something very sweet met her lips, a tongue of pure sugar invading her mouth. She lay there, helpless and afraid, until she felt those emotions drain out of her, slowly. In their place came the urge to kiss back. Not just kiss, but really take advantage of her froggy tongue, which was twitching with a mind of its own. She felt her blood rushing to her crotch, something poking at it... No, something growing out! The usually calm girl started to panic at about the same time her uniform's top was ripped off, her assailant licking and sucking on the sensitive nubs atop her large breasts. Whatever it was that was growing between her legs was getting her underwear painfully cramped. Seemingly reading her thoughts, 'Ochako' tore off her skirt and underwear in one swift movement, and Tsuyu shrieked as something warm fell onto her chest. The black haired girl knew what it was, but she dare not think it. It was big, at least some good nine or ten inches long, and about two wide. It was sticky and warm, and a cap or foreskin covered the head of the throbbing shaft. It only got harder as Uraraka gripped it tightly, but not enough to hurt. Asui let out a small moan as her best friend stroked her, giving the shaft small kisses here and there. The bunny woman peeled off the foreskin, wrapping her soft lips around the head of the thick shaft. The corruption having done its job on Tsuyu's inhibitions, she gripped her partner by the fluffy ears and pushed her down on the throbbing shaft, prompting an excited squeal. Her throat was unbelievably soft and flexible, but still just tight enough that the recently corrupted frog let out a groan and exploded with her first male orgasm. Not wanting to leave her feminine side untouched, she let go of Ochako, spreading her glistening lower lips, hidden behind her recently drained sack. The sweet rabbit took the hint and her own shaft stood to attention. Both their minds drowned in a lust filled haze as one entered the other, and they lost track of the hours they spent getting each other off. ... Tsuyu stood in front of the mirror, rubbing her cum-bulged belly. She'd returned to her room after Ochako passed out in her upteenth orgasm, but she still missed the sensation of being filled. She licked a speck of cinnamon cum off her finger, turning the light off and lying down on her bed. She settled for letting the rabbit take her in her dreams, unaware that the real changes to her body had just begun. ***** Bull Frog ***** Chapter Notes Shorter chapter this time, sorry about that The next day, Tsuyu woke up with a massive headache and an even bigger hard-on. She decided to deal with the throbbing in her head before the one between her legs, but putting her hand to her forehead, she felt something different. Her fingers met with two pointy somethings, smooth and rounded upwards. Horns, most likely. After how Ochako ended up, she figured she wouldn't stay human, or even just froggy. Speaking of, her skin was now a pale green, and just a little slimy. She thought it best to take a proper look at herself in the mirror, but fell down to the ground, not used to her new hooved feet. In fact, her whole legs were replaced by those of a horse's or a cow's, fur and all. Sitting back up, she was met with another change: her shaft was big enough to easily tower over her when sitting down. It was mottled with black and white, much like her legs, and the head seemed much flatter than the previous night. Even her sack felt much heavier, each nut about the size of a small soccer ball. It would probably have made it harder to walk, had she still had human legs. The smell of it all was intoxicating. Her tongue twitched, aching to wrap itself around the throbbing length. So she let it. Her lids felt heavy as she licked herself, probing her prehensile tongue all over the thick pole. She felt it would be hard for anyone except spongey Ochako to wrap their lips around the monster. But it still wasn't enough. She reached for her breasts, taking a few moments to grasp how big they had gotten. She could feel four bumps on each one through her shirt, all leaking warm milk. She smiled and let out a soft "Moo~" as she wrapped the flesh mounds around her shaft, her lactation lubing it up as she pumped up and down, nearing the first of many orgasms that morning. ... The night was silent. Two figures moved away from the school dorms, headed to one of the many unused training facilities. In between their unending humping sessions, the two corrupted girls had agreed that staying so close to so many witnesses wouldn't end well for them. They could pass for normal people with unusual quirks outside, but most of their ex-colleagues would be able to recognize them. UA's training facilities were mostly city-like anyway, and they rarely got that much use. They both had enough stealth and combat training to go by unnoticed and get some food from nearby convenience stores, as long as no particularly skilled pro heroes were on patrol. It all seemed well, and it was. Until around five days later. Please drop_by_the_archive_and_comment to let the author know if you enjoyed their work!
