With Pyren and Sapphira alone, Pyren brought up a tentative idea. "Sapphira... I know we're just... boyfriend and girlfriend as it is now, but... would you be willing to try... some things?"

"What kinda things, Py-py???" Sapphira wasn't sure about what pyren meant...

"Well..." Pyren paused. "Well... naughty things..." He covered his face and looked away, embarrassed to be asking

"Ummm, ok??" Saph really was a child, at least, she was innocent, despite the chaos she caused sometimes...

"A-are you sure?" Pyren asked. "I don't wanna put you up to anything you don't wanna do..."

"I'm up for anything! Why are you acting like me...? I-is this something.... bad???"

"Well... not if you don't want it to be." Pyren admitted. "Well... I'm asking if you want to do some intercourse, or something..." He didn't want to bluntly state that he wanted to try sex with her.

"Sure, what do I have to do???"

"Well..." Pyren began. "Maybe we should do this in bed, at least to start." He led Sapphira to his room and laid down in bed.

Saph paused, before hopping onto the bed. Being only 2 feet tall made life a bit difficult sometimes...

"Alright... Now you need to take off your clothes." Pyren said.

"Wh-wh-what??? My... You are sure...?? I don't really like to be out of them...."

"Well... You can keep the shirt but... You kinda need to take off the pants if we're going to do this."

"Ugh... fine..." Saph hopped back off the bed and took a moment getting the thing off her hips. "Having a shape like his actually makes this difficult..." she muttered, hopping back up once she finished...

"A-alright." Pyren said, blushing at the sight of her pussy exposed. "Now lay down... I'm going to go slow."

“Ok...?" sapphire hadn't any idea of what he had planned...

"Alright..." Pyren said, sitting up and nudging himself close to her. "Tell me if you want me to stop." He said before pushing his flaccid cock against her womb and grinding against it slowly

"What are you...?" Saph wondered before a strange sensation took her, as she began to grow rapidly...

Pyren wasn't surprised to see Sapphira growing - in fact he was expecting it. What he didn't expect was that his own growth powers would trigger so easily too. He grew about half as fast as the Sableye did but he grew none-the-less.

Saph was the same size as Pyren now, for however long it would last...

Pyren decided to penetrate her, since they were same size. He pulled back and slowly pushed his length into Sapphira. The vagina felt nice and warm and the flesh pleased Pyren's cock, speeding up his growth

Saph groaned... what was this feeling?? She grew again, nearly hitting the ceiling this time!

"A-are you enjoying it?" Pyren asked, hoping he wasn't hurting Sapphira thrusting into her already. He assumed she was a virgin...

"I-I guess so,.,," Sapphira's next spurt took her through the ceiling, right into Amelia's room! "OOF!"

Amelia was sleeping at the time and woke up to a giant Sapphira being penetrated by Pyren. She was astonished, but intrigued at the same time. Unfortunately, Pyren immediately noticed her and grabbed her. "No peeking." He said, stuffing her in his mouth.

"Hehe, Amelia is so naughty, isn't she??" Saph smirked, before panting as she grew again, now starting to surpass Pyren again

Pyren nodded and swallowed her effortlessly with his next growing spurt. For some strange reason eating the Mawile seemed to intensify his next growing spurt, making him twice as big as Sapphira and outgrowing part of the house. His dick became too big for her vagina.

Saph gasped, now stuck on his length... "AUGH... H-hit me, Pyren... I-I need to grow, here....!"

Sapphira was far too tight for him to effectively move, and he feared another growth spurt from him would seriously injure Sapphira. "I c-can't move!" He exclaimed. "T-too tight. Lemme..." He leaned down and kissed Sapphira as deeply as he could, hoping the affection would make her grow.

Saph grew all right, but it seemed that whatever had made his spurts larger, had made the ones he caused larger, too! Saph quickly grew, until Pyren was a doll to her! "Oof, that is better, huh??" she said, smirking at Pyren. "A second kiss like that, and we could play a different way..."

Pyren was more relieved to be free of Sapphira, more for her sake than his. "You certainly grow big, hon." He said, seeing her atop the house. His cock throbbed hard with need, leaking a decent amount of precum which stuck to her vagina. Even without thrusting he was growing very slowly, just a little pulse every moment almost in sync with his throbbing cock. He started licking the outside of Sapphira's pussy, hoping to arouse her and make her even bigger.

Saph grew all right, swiftly becoming more of a building to the giant fire monkey, her opening more than large enough to admit him, if he so chose...

Pyren started to crawl inside of her, grinding himself against the vaginal walls of her insides. He was enjoying his disposition in their intercourse, him making her bigger and bigger with every thrust of his hard length. The thought alone was bringing him close.

Saph was groaning too, but she had a thought... "P-pyren, y-you better get out before you grow again... y-y-ya might rip me apart if ya do in there...!"

Pyren grunted upon hearing her words, realizing the mistake he was making and crawling out of her. He continued to grind himself against her outside and, indeed, his climax hit and he had a massive growing spurt. Every shot he made doubled his size, so rapidly that he had to pull out quickly to keep from hurting Sapphira. Given his productivity, he kept growing for a whole fifteen seconds before he stopped, rendering him larger than mountain-sized. Pyren was left gasping and panting from his first climax. "Oh g-god..."

Saph merely gaped, the Monferno was WAY too big for her to take now! She simply walked forwards and tapped on him, trying to get attention.

Pyren glanced down at the tiny Sableye, who was hardly half the size of his cock. "G-god... Orgasm really makes me big..." He remarked. "I'll b-bet it has the same effect on you."

"Yer too big to do it, though! I need to grow! Help me!" She banged on him a bit with her fists, trying to get her point across.

Pyren moaned just a bit as she punched his cock. He picked her up and put her atop his length. "I'm t-too big to kiss you, so g-grind against me." He said, pulling her legs apart so she straddled his cock to show his meaning.

"Pyren, you forget something? Just hit me, yer a big strong monkey, so a simple flick would do it!!"

Pyren smirked. "Aaw... t-that'd have been more fun." He said, giving her a quick flick on the head with his giant fingers.

Saph grew from this, though it did hurt, she smiled, now at least big enough to kiss, as she called up to him to try  it now...

Pyren leaned down and kissed her as carefully as he could. They both grew as their affection showed.

Sapphira smiled, letting some of her own power speed up the process, until she was big enough for him to try the naughty again,...

Pyren smiled. "Are you enjoying this?" He asked, grinding himself against Sapphira again.

Sapphira nodded, she had the oddest impulse to bite down on her thumb, but resisted. Do THAT and she could kiss it GOODBYE! Something was rumbling inside her as she grew more...

Pyren could tell from her quivering that Sapphira was close, and he figured she's seriously outgrow him. He quickly came up with a few ideas and started thrusting into her. He couldn't help but be amused that their sex could be seen by the whole world, as it was the last thing it would see before they crushed it with their growing immenseness.

Sapphira finally felt an intense burst, as she grew fast, swiftly smirking as she pushed the Monferno back inside her as she continued growing, needing nearly a full minute to finish, panting as she floated in space, already beginning the slow growth from passing her limit...

Pyren was amazed she had grown so much, but he shouldn't have been surprised. He started jerking off his member, encouraging his growth to speed up. Meanwhile, he looked around and tried to pick out any sweet spots in her womb he could grind against - those sensitive spots that would make Sapphira explode with growth!

Sapphira suddenly cried out as he reached one of those spots, as she exploded larger, leaving Pyren with a slight problem: he spot was too big for him to get off of, and every step he took seemed to increase her size even more, as the purple cavern around him stretched and grew by the second!\

Pyren smirked as he was faced with this dilemma - that any movement of his would arouse his girlfriend more and more until an extremely powerful climax took hold. He got down and started grinding his length against the womb, pushing Sapphira bigger and bigger!

Finally, Sapphira's thunderous roar was heard once more, as a tsunami of fluid came rushing towards him, growing rapidly as it did so...

Pyren was washed up by the tsunami of femcum and forced out of the womb, getting to marvel at what he had done to Sapphira!

Sapphira basked in the glow, looking around before FINALLY managing to stick Pyren to a fingertip. "That was... WOW!"

"I hope you had fun, baby." Pyren said to her.
