Monster Period
🕑 Added 2023-08-06 05:12:01 +0000 UTC Story by Leena “God, I hate this,” Lizzie said. “What's wrong?” Carrie asked, looking at her friend with concern. They had decided to get together for a movie night a long time ago, and Lizzie had been talking about possibly backing out all morning. But they decided to go through with it. However, now that the two were together, Lizzie looked like she was straight out in pain. “It's my period,” Lizzie said. “I always get horrible cramps like this.” “You never complained before,” Kerry said. “That's because I usually medicate it away,” Lizzie said. “You can medicate your period away?” Carrie said, questioningly. “Yeah, I'm on birth control. Birth control usually has a week of placebos to keep you on your period. But there's literally no reason to skip that week. Medical science has shown that it's perfectly safe. And when you do, you just don't have your period anymore. You can't get pregnant either, but for me, that's a good thing.” “Really?” Carrie said astonished. “Then why do we take the placebo week?” “Oh, I could start ranting all about that. Short answer, it's misogyny. A bunch of men decided that women still had to be in pain for it to be natural. It's all problematically wrapped up in religion, too. But they're just a lot of women out there suffering when they don't have to.” “Okay. So, why'd you go off it?” “I didn't want to. There's just a problem with my pharmacy. My pills have been delayed for a week. Which means Aunt Flo is coming.” “Oof. Sorry. When will they have more pills?” “Probably in another week or two. I need to call the pharmacy tomorrow. They've had shipping problems, and it keeps getting lost in the mail.” “That’s rough. Well, I think that I have some pain killers in my purse, if that would help.” “No, that's fine. I think I just need to lay this egg and be done with it.” “Lay an egg what are you talking about?” “Oh God, it's coming!” Lizzie said she backed up and leaned against the wall. “OK, just get me some water. This should be done in a second.” She started breathing heavily as deep cracks started coming from her body. She gritted her teeth as sweat dropped down her brow. Carrie stepped back and watched in horror as Lizzie's hips began to crack. They started to widen, her jeans straining against their expansion. “What the fuck is what's happening to you?” Carrie said in fear. “I told you my periods were monster periods, right? I guess I just didn't say how monstrous they were.” Lizzie's teeth started to grow sharper, crowding her mouth. Her tongue extended long and pointed. Her words started to come out as hisses. A third eyelid closed over her eyes as they became yellow, slitted and reptilian. “I told you I was a mutant before,” she said, grunting through the pain. “Yeah, but you said your mutation was minor,” Carrie said. “Yeah. Uh, it only shows up when I'm on my period. Oh, shit it's coming hard now.” Lizzie braced herself against the wall as her hips continued to spread. Her body began to grow, shredding through her clothes. Her knees locked in place and then cracked and bent backwards, as her thighs bulked up. Her toes stuck to each other and extended outwards, shaping themselves into three toed talents. Her heels grew out into a dewclaw that operated a bit like a hand. As scales started to push out of her skin, she squatted low and moaned as her underwear shredded to pieces. Carrie could see her pussy literally pulsing in front of her. “Oh, fuck oh, fuck oh, fuck fuck fuck. Oh, fuuuuuuck.” “What the hell?! Is this normal for you?” “It was. Then I got on birth control. Why do you think I got on it in the first place? Oh god, oh fuck it, it hurts.” Lizzie tilted back her neck and let loose a dinosaur like screech. Growling as her arms started to extend long and spindly. Her fingers merged down into three as her nails grew sharp. The skin on her thighs reached up to attach to both her legs and arms, growing into flap like wings. She looked like some sort of pterodactyl girl. And she was growing rapidly. “God, Lizzie, what can I do?” “I told you just get me some water,” she grunted, frustratingly. “You know, for the one who's transforming into dinosaur here, I'm really the more levelheaded one. You'd think it was you who was mutating.” She forced out a laugh, and then suddenly groaned in pain. The scales had covered her whole body, her skull had pushed backward into a pterodactyl like head. She had already grown another foot in height and was still growing. She was beginning to cramp her apartment. “I'm almost there. I'm almost there,” Lizzie grunted. Lizzie spread her legs as her pussy and asshole slowly merged together into one hole, a reptilian cloaca. It spread wide as a greenish white orb started to push through. Her claws scratched at the wall as the egg started pushing out of her body more and more. She screamed and screeched, and with one final push managed to get it out. Afterwards, she collapsed on her floor. Carrie still staring at her in shock. “Thanks for the water, Carrie,” she said sarcastically. “Sorry. I just, I've never seen anything like this before.” “Yeah, my mutation is attached to my hormones,” Lizzie said, catching her breath. “Small bits can peek out whenever my emotions are high. Maybe a scale here or there. Some sharp nails. If I get horny, I might transform a little bit, but it's all easily hidden. But when my period hits hoo boy. The eggs come, and I gotta lay them.” “Eggs. Plural?” Carrie asked. “Yeah, unfortunately, I'm gonna be stuck this way for about a week. I'll be laying every day until I change back. Or, I guess, until I get back on birth control, if my pharmacy was competent, this wouldn't be an issue.” “Wow, so your periods really are monster periods. As in, you turn into a monster.” “Technically, I turn into a pterosaur. But, you know, whatever works for you.” “Is this a bad time to say that I wanted to watch Jurassic Park tonight?” “Oh, will you shut up? And seriously, can you get me that water? I feel another one coming out.”
