Work Text:
Aside from being biologically zanthen, Erin was as human as they came. She was an all-American girl, raised by human foster parents with human siblings. She had earth pets like dogs, cats, and chickens. It’s not like her foster parents were anti-zanthen or anything (far from it, since they explicitly fostered and adopted a zanthen), but they were sort of…clueless. You know how it goes: mom and dad were raised by conservative parents of their own, so body-talk was still an uncomfortable topic, especially when it came to other species.
Cue Erin’s Sunday surprise.
Everyone else was at church: mom, dad, and the siblings. Erin complained of a tummy ache, so her parents encouraged her to get some rest at home.
Erin sat up in bed with her knees to her chest. Her favorite pair of jammie pants clung to her hips. She wore a white camisole, showing off her naturally pink arms and chest. Her forehead pushed into her knees, and she grimaced at the cramps that came in waves. It felt like she was having menstrual cramps, except they weren’t in the right spot. Not exactly. These cramps were lower. Closer to her butt.
She peeled herself out of bed and clutched her middle. The stuffed animals littered across the bed toppled as she stood. Erin shambled to her bathroom, pulled down her pants, and sat on the toilet thinking that maybe a good poop was what she needed.
Her bowels were fine, but what did stand out was a small, swollen appendage sticking slightly out of her private parts. Erin gasped. Was this…her ovipositor?
The poor girl felt her heart race. It was insane to think that this was her ovipositor, because she thought she was way too young to go into rut. Erin didn’t know much about rut, only that every zanthen went into heat and rut; when they were in heat, they could become pregnant, and when they were in rut, it meant they needed to lay their eggs. But if that little, pink appendage was any indication of rut, then that meant…
Uh oh, am I going to lay my eggs for the first time? she thought.
Erin stood up and pulled her pants up. Well, that explained her tummy ache. But how were the eggs supposed to come out? What if…what if they started coming out when her family got home?! She bit her lip and whimpered, hating the very thought. No. She couldn’t let that happen. She had to get the eggs out…now!
She walked over to her desk and felt a tender cramp. Moaning quietly, Erin placed her palm on her belly, rubbing the area. The touch felt…intense. Provoking. She sat at the desk and booted up her computer. It took its time and while it did, she rubbed her belly some more. She let out a soft hiss, a sigh, a deep breath. She glanced down and saw a wee bulge forming in her loose pants.
With a grimace, she spread open her legs and stared dubiously at the bulge. She had to get those eggs out.
Her computer finally awake, she opened her web browser and searched “how to know if ur in rut”.
A series of results popped up, the first describing the most basic symptoms. The first signs of rut included cramping around the area of the eggsack above the perineum. Well, that tracked; the pain seemed to be coming from somewhere between her tummy and butt. Other symptoms included sweating, heightened arousal, and stiffening of the ovipositor in preparation to lay eggs. Once the ovipositor begins to protrude from the vulva, a zanthen should lay their eggs in approximately a half-hour to 24 hours.
“A day?!” whined Erin. “I can’t wait a whole day!”
She deleted the search and typed in “how to make eggs come out faster”.
Her computer answered her by way of academic articles about chickens.
She rolled her eyes. “That’s not what I meant!” Erin deleted the search and instead typed in “how to make zanthen eggs come out quickly”.
SAFE SEARCH IS ON. WOULD YOU LIKE TO TURN IT OFF?
The shy girl chewed on her lip. She was always such a good girl and never searched for anything remotely sexual. She wasn’t sure how her parents would respond if she accidentally stumbled across something…sus. But she had to try. Those eggs couldn’t stay inside of her. The longer she took, the more swollen her ovipositor was getting. She could feel her vaginal walls squeezing against it. It made her feel funny down there.
She clicked yes.
Fortunately she didn’t come across anything she would deem taboo. Just a lot of helpful wiki-type results. She browsed through a few websites. There seemed to be tons and tons of advice, ranging from massaging the ovipositor, to inserting something into the rectum to stimulate the eggsack. Well, Erin certainly didn’t trust herself to stick something directly inside her own butt, so she started simple:
She swallowed, took a deep breath, and began to pet her ovi with the palm of her hand right through her pants. It felt…warm. Electric, almost. At first, she felt a little contraction inside of her that caused a nasty, little cramp. She moaned through it and continued petting herself. Soon, the sporadic, little contractions felt…tight. Like friction.
“That feels…kinda good,” she relented.
She pet and pet and pet herself, the sensation starting to feel more natural and quite frankly, delectable. She remembered reading that another sign the eggs were close to coming out was that the ovipositor would start to leak pre-ejaculatory fluid. In practice, this fluid would coat another zanthen’s vagina to prepare them to receive eggs.
Erin tugged her waistband open and looked inside her pants. She gasped. Her ovipositor was about two inches long, sticking out of her privates. It was a few shades pinker than her skin, and swollen to the touch. And sure enough, its lightly pulsing head was dripping with clear fluid.
Curious, Erin pressed two fingers against her ovi. She closed her eyes and hissed. It was sensitive to the touch and twitched back at her fingers in response. With its twitch, more fluid drained out of its head. She slicked her fingers with it and cautiously tasted it. It was…salty. She rubbed her fingers on her tongue, letting her salty tongue roam over her lips, and simply tasted for a moment. The curious girl shrugged. The taste was neither here nor there, and she wiped her sticky fingers on her pant leg before using her fingers to rub her ovi again.
Now that felt good. Her smooth strokes were making everything pulse down there. Maybe she really was close to laying her eggs. After all, her butt and tummy felt…full.
Erin let her waistband go but kept toying with herself in her pants. The occasional moan or mewl left her lips. She simultaneously scrolled through more search results on the computer.
One that surprised her was that it was more common than not for zanthens to orgasm upon releasing their eggs. Erin’s heartrate increased again. She had never had an orgasm before. Heck, she had hardly ever touched herself. There was no time to explore those sorts of things, not when you had so many siblings in a house so full.
Another result told her that once a zanthen began to lay their eggs, it was almost impossible to stop the eggs from coming out until the eggsack was spent. For a zanthen’s first time where a partner was not involved, it was suggested that a person ejaculate into the toilet, a large bowl, a bag, or another container that could catch the sperm and eggs.
She didn’t know why, but Erin was starting to feel very, very turned on. Her fingers waggled at the head of her ovi, which was still producing copious amounts of pre-ejaculate. There was something about touching her swollen appendage, and reading about all those eggs that needed to be set free, that really worked her up.
“Lean into it!” another article read. This one was a blog post from some kind of sex guru. “Don’t hold back and enjoy the ride. This is perfectly natural, something that’s meant to be savoured. Ways you can enhance your breeding experience while flying solo are: Moan, baby, moan! Be as loud as you catch! Hearing yourself moan is sexy.”
Shy and awkward, Erin blushed. The next time her fingers teased her head, she released a cute, quiet moan. “Th-that feels good…” she said with a shaky breath. But as awkward as she was, it did feel good. Her ovipositor felt very, very good.
“Your body wants you to breed someone, so breed someone, baby!” the article continued. “Play pretend. Your body wants you to get somebody pregnant. So pull up a pillow, picture your favorite hottie, and breed her. You can cum right into the case.”
Shaking lightly at this onslaught of new and chaotic information that opened doors Erin hadn’t realized were there, she looked over her shoulder at her bed. She had a couple of pillows, sure, but her mom sewed those pillow cases for her. She couldn’t use them like that. And she certainly wasn’t going to breed one of her poor stuffies…
…was she?
There was Unie the Unicorn: three feet long, with her opposable legs, mane of wild hair, and big, plush, beanbag belly.
“Um…Unie?” asked Erin with a trembling breath, standing from her chair. She was cupping her entire ovi now, squeezing and rubbing herself off through the sticky mess. Wet sounds could be heard in her pants. She approached the unicorn. “Unie, I, um…” Her crotch pulsed and she doubled over slightly. She didn’t think she was going to last much longer. “I um…I um…I have a favor to ask, and um…”
She pulled her hand out of her pants and shakily held the unicorn. She looked into its dark, beady eyes and swallowed. “Well, I need somewhere to put my eggs. But d-don’t worry…I can help you out, too…”
Erin’s hand slipped between the stuffy’s legs. She began to massage the area where she imagined its privates would be. She had intense butterflies, and was blushing something fierce. Still, she wrapped an arm around Unie and massaged what Erin pretended was her pussy.
Her ovipositor was starting to feel very, very swollen and needy. The longer she rubbed Unie, the more turned on she felt.
“What, Unie? You said it feels good? I’m glad,” Erin smiled, and pushed her fingers into the soft fabric as far as they would go. She could feel the sandy bits inside when she pushed. “You feel wet. It’s kinda making me feel wet, too.”
She continued fingering the fabric and leaned in to kiss Unie on the mouth. They were soft, gentle kisses at first, but eventually, her tongue slipped out. The fabric was smooth and stretchy almost like activewear. Erin moaned into the kiss, fingers moving the way she would have liked.
The kiss grew deeper and deeper and deeper, and Erin’s body deepened too, until she was towering over Unie. She melted on top of her stuffy, Erin’s leg slipping between the unicorn’s two legs. They were interlocked now in the scissor position. Instinct drove Erin’s hips into the stuffy’s crotch.
A real moan escaped her. Erin had never humped before, and this newly discovered movement of her hips, this gyration, was the single most arousing thing she had ever experienced. All she knew was that she had to keep humping.
Erin clumsily pulled down her pants, trying not to stop humping as she did so. It ended up with choppy, crude motions and desperate thrusts. Finally the pants were around her ankles. Her swollen, almost frothing ovi was rubbing against the unicorn’s smooth crotch.
There were now wet stains on the unicorn’s mouth and crotch. The bed started creaking as Erin humped Unie to oblivion. Every thrust elicited another sweet moan from her. “Oh Unie! Oh! It feels good!”
And then, something new happened to Erin.
White.
There was white coming out of her ovipositor. There was white coming out, and something else was happening. Something intense, deep, deep in her core.
“Uh oh…omigod…” she panted, stopping her thrusts immediately. She could NOT ejaculate on the unicorn, what was she thinking?! But oh god, she was going to breed something right now!
Erin clutched her ovi in her fist to try and stop it, but it was no use. She whimpered as a half dozen eggs squirted across the rooms. They splashed against the wall. “Oh fuck!” In an instant, she was back on top of Unie, grinding her messy ovi up and down against its fabric. On the verge of her second orgasm, she rubbed and rubbed until a whimper came out and a trail of thick, messy semen. She rubbed her ovi in her own seed and kissed Unie again, making out and ejaculating for several more minutes. The friction was intense and overstimulating, and Erin couldn’t take it for long. “Mmmmmph!” she moaned into the kiss, her insides contracting, and another half dozen eggs spurting out of her ovi.
No literature in the world could have prepared her for how intense egg-laying was. Her body demanded that she breed. So it was Erin’s imagination that told her that Unie was in heat for the first time, and her pussy was so, so ready for her eggs.
The poor, needy girl scissored the unicorn and came again, eggs trapped between their bodies, some tumbling onto the bed and getting squished beneath Erin’s weight.
“Good…girl…” she panted, breaking the kiss and patting the unicorn’s beanbag tummy. “Ooh, your tummy’s so full of my eggs. Here, just let me…NGGHHH!” Splurt. With a modicum of control, Erin rode her contractions and fertilized Unie with her sperm. Erin laughed lustfully, holding Unie’s mid section, pressing light kisses to it. “Mmm…look at your big, pregnant tummy. You came so hard, Unie. Let’s get you bred,okay?” Erin stroked herself off, and every few seconds, the last of her cum would drain onto the unicorn’s belly.
Finally, Erin looked at the mess she had made. She was a little lightheaded and woozy from the whole ordeal, so she sat back down at her computer, leaving the used Unie to fend for herself for the moment.
But when Erin sat, she felt…butterflies. Another pulse. A cramp. A throb.
She opened her search bar and typed “how many rounds of eggs does a zanthen lay”. After reading a few results, she went right back to biting her lip. Her little, swollen ovi twitched as if to confirm the results. “Uh oh…” sighed Erin, looking back over her shoulder into Uni’s eyes. “Um, Uni?” A deeper throb emanated below. “Oof…can you please bend over? I think I need to…”
