Kumiyo felt some anxious about her upcoming conversion. It wasn’t that she was having second thoughts about becoming a Tylosaurus Dinotopian. Sure, it was definitely a very large marine reptile and would make her a big Animalian. But what bothered her the most was her dating potential afterwards. Kumiko had it easy, the orca who helped convert her also became her mate quite readily. It may be because an uplifted Animalian had less concerns about social standards.
The only other Tylosaurus was her sponsor, Tyson. While he didn’t seem to be a bad man, but Kumiyo wasn’t sure how much they’d have in common asides from being matching species. Having incompatible personalities didn’t seem very likely, but a relationship that is mainly based on hormones is not stable at all.
Anyways, Tyson wanted to be a gentleman about it. He could have converted her directly, but he opted to just provide the doses of activated Animalian virus to put in her shots. "Do you think he doesn't like me?" asked Kumiyo to the nurse who was giving her the shots.
"The two of you just met," said the nurse, "It may be a bit early to decide whether you like each other or not. But I wouldn't say he doesn't like you, more like he doesn't trust himself."
"Why not?" asked Kumiyo.
"As you'll soon see, Animalians have a pretty strong libido and Tyson hasn't been able to relieve his for a while. Even without any other Animalians of his species, there are few that are big enough to handle him. So he's rather pent-up and doesn't trust himself to take advantage of you," said the nurse.
"Maybe I should be take advantage of him," said Kumiyo.
"Well, it's not my business, but it might do you both some good," said the nurse before injecting Kumiyo, "Welcome to Dinotopia." With that, she left the room.
Kumiyo felt her muscles tingling as the virus spread through her system. She was waiting for the tingles to get to her back and make her strong enough to lift herself up. But the first changes was her body growing. She wasn't going to remain tiny by any means. Her small Japanese frame was growing taller and taller, her limbs becoming thicker with muscles. Her clothes quickly tore apart from the strain. She outgrew her custom bra for the last time, but her breasts were already becoming less saggy as her pectoral muscles strengthened. They became less dwarfing as the rest of her body was growing to match them.
Kumiyo's inhuman features started with her skin changing color. Her pale porcelain skin was turning grey, a lighter grey in the front and a darker grey on the back. Kumiyo gritted her sharpening teeth as her face started pushing out. Her ears dwindled into two small holes that became covered in a waterproof membrane. There was a brief tingle in her scalp before hair fell out. Kumiyo regretted that part, but she knew Dinotopians didn't keep their human hair. She felt her throat grow thicker, wondering if she was feeling her secondary jaws forming.
Her fingertips were becoming more claw-like as grey webbing grew between her fingers. Her feet grew longer as the webbing covered most of her toes to make them more like flippers. Her coccyx pushed out before it started forming into a long thick tail. Kumiyo grew straighter and taller as she truly grew into her bust. No longer feeling like dead weight on her chest, neurons fired off pleasurable signals as mammary glands started producing milk. The pleasure soon reached her groan, making Kumiyo groaned. She didn't just want Tyson, she needed him.
==========
Tyson headed to Kumiyo's room as soon as he heard she called for him. He steadied himself at the door, reminding himself to not let his groin do the thinking for him. He cautiously opened the door and stepped in. He nearly stepped out when he saw Kumiyo was only wearing a bed sheet draped across her body and it was just barely enough to cover her larger frame. "I'm sorry, I thought you were ready," Tyson said, averting his eyes.
"I am ready," said Kumiyo, her voice a little deeper from speaking from a bigger chest, "I've got such a fire inside me and I need you to put it out."
Tyson pinched his forehead and groaned, "That's the worst come-on line that I've ever heard."
"Hey, I'm new to this," said Kumiyo, "There aren't as many guys as you'd think who'd want a girl who's been 'cursed by a cow demon'. They treated me and Kumiko more like sideshow freaks than girls to lust for."
"I find that...surprising," said Tyson, stealing a quick at Kumiyo's bust. Even as a Tylosaurus, she was quite busty. The main difference was that her breasts were in better proportion with her body. The rest of her was well-proportioned as well.
"Boys in my country have different tastes than yours," said Kumiyo, "Ok, I know I came on strong, but I've just gotten this new sex drive and I know yours hasn't been taken care of. Couldn't we at least help each other as friends? What is the term you use?"
"Friends with benefits?" asked Tyson.
"Ah, now I get it," said Kumiyo.
"Well, I suppose we both have needs and we don't have to commit just because we're of the same species," said Tyson. Besides, he couldn't deny how turned on he was.
"Ok, just remember," said Kumiyo before dropping the sheet, "It's my first time."
"Well, I'll have to make it special," said Tyson as he took off his own clothes. As soon as they were both on the bed, he started by fingering her vagina. Kumiyo moaned as she got damp, but Tyson wasn't just only to apply his fingers. Lowering his head, he started licking her slit. He was a little tempted to let his second jaws out to nibble on her, but those jaws were more suited to chomping. With a little more coaxing, he soon brought her to climax.
Now that she had her first taste, it was time for proper sex. Tyson lined himself so that he was gently probing her. He gave her a short kiss before plunging in. Kumiyo moaned loudly as she felt herself being filled out for the first time. Her breasts bounced as Tyson thrust, but they no long felt like a burden. Especially when Tyson started playing with them and sucking the nipples. A little bit too soon, they both hit their climaxes.
"Er, sorry about that," said Tyson, "I usually hold out for longer. I guess I was more pent-up than I thought."
"Well, I came fast too," said Kumiyo, "Perhaps the next round could be slower."
"I'll try, but it's been a little too long since I've been with a woman," said Tyson.
"Then we'll have to get it all out of our system," said Kumiyo. Maybe this wasn't meant to be more than a sexual relationship, but it would at least be enjoyable for now.
