Chapter 1: Stimulation

Chapter Text

Peridot’s log, seven three six, six. I have procured a most mysterious object from the Steven’s patriarch, the Greg. He was very flustered when I stumbled across it in the barn, I figured it was some sort of weapon or currency only the posing of the woman on the front suggested otherwise. Clearly this “Playing of the Boy” is a treasured earth item for the male units of this planet. Though the choice to use a ra-bid as the coat-of-arms for this item is a bit strange, I’ll need to do more research into this long-eared creature to understand it choosing. Surely the lion or dog would make a better symbol, as the former represents primal masculinity and dominance while the latter is a male’s best friend. Some of the pages were stuck together and had to be gently pried open and the whole thing reeked of a strange odor I’ve never smelled before. Curious that such a precious item is treated so crudely.

The “Playing of the Boy” is filled with imagery of human males and females, mostly females, engaging in mating rituals. Some I’ve seen before, some not at all. I wasn’t even aware an organic spine could bend that way. This external male organ, the “Cock” is intimidating, so large, it looks like it would hurt and yet the human females are accepting them into their various orifices, except the ears and nasal passages. I wonder why? Another source of intrigue is in the various facial expressions the humans are making, they seem to be enjoying it, though I suspect their facial expressions have been altered. I clearly need a more thorough investigation of this material, further analysis to be done at a time where I can be alone. Peridot out.

 

Peridot did have to wait long for her opportunity. A mere day after acquiring the magazine all of the gems went out on various missions while Steven went to spend time with Greg and Connie. Peridot had the run of the barn and the beach house. Feeling the beach house would be a more sanitary location, Peridot teleported in and took over Steven’s room, flipping through the magazine to get a better feel of the various bodies featured in the pages. Oddly enough she came across a thin white haired and fair skinned woman with large breasts that resembled pearl and two dark skinned women, one tall and one short who resembled Garnet and Amethyst, respectively. The pearl looking woman was sat in a faceless man’s lap riding his dick while the other women were on their knees suckling the cock of another. Peridot flipped until she got to a section of the magazine that read, Masturbation: Where to please yourself and how!

“Ooh! So, the humans practice a sort of self-pleasure ritual. Interesting.” Peridot said, slowing down the pace of her flipping, “Yes I wonder if its similar to the one Jasper performed on the way over here. I certainly hope not.”

Resuming her observations, Peridot was greeted to the sight of various women, most medium to large breasted and most, if not all, bottom heavy. They ranged in terms of skin color and hair styles, in fact Peridot barley even paid attention to their faces. They all just looked so…enviable.

“Oh wow.” She said, drinking in the sight of an Indian woman fingering herself. “I never knew humans had such fascinating anatomy! Although its abundantly clear all of these women had enhancements to their physical forms. I guess our species aren’t so different after all, everyone needs help to do their job every now and then.”

After flipping through some more pages, she stopped at a page that had the word, Shortstack written in a green similar to her skin in the upper left corner. Underneath it was a short woman with breasts and a butt which were very large on her. Feeling drawn in Peridot put the magazine down and gazed at the image longer than she should’ve.

“Hmm, I quite like this form.” Peridot said, standing up. “I could probably replicate this form, Amethyst is always going on about how I lack in the shapeshifting department, but thanks to the Steven tinkering with my gem, albeit in an unsanitary manner, I’ve been improving. Yes, I will replicate this form to perfection!”

Taking a mental note of the form she wanted, Peridot first removed her attached clothing, revealing her featureless and genitalia free body to absolutely no one. After a few minutes of hard concentration and almost sweating her gem off, Peridot had changed her body into a near replication of the one in the picture. Her breasts were supple but not larger than a C, whilst her bottom and thighs had become much thicker. Round spherical cheeks similar to, but smaller than Garnet’s complimented her backside. She’d always been a little curvy but now her hips were much wider and rounder, she even grew a little taller. In between her legs, a dark green vagina was perfectly replicated. The dark green matched the shade of her nipples and areolas.

“I…I did it…” Peridot said, shocked at her new body, “I did it!”

Peridot jumped for joy, feeling a little woozy, she wondered how long she could even maintain this form. She didn’t let that stop her, however.

 “I knew I could do it, Peridot you are a genius!” She complemented, “Now…how do these things even work?”

She grabbed her new breasts gently and felt a slight shiver wash over her gem and body. Similarly, the closer her finger got to her pussy the tighter her stomach felt.

“Is this normal?” She asked aloud, “This vagina is strange, it feels like a weak spot. Was it designed specifically for the human dick? Clearly this requires further investigation in the fields of, ‘self-pleasure’.”

Peridot flipped back to the masturbation section of the magazine and skimmed though it until she came across a picture of a woman laying on her bed, legs spread, pussy moist with liquids dripping on her thighs and bear crotch area.

“Log date seven three six seven.” Peridot said into her tape recorder, “This human in the picture seems to be secreting some sort of fluid from her vagina. Perhaps if I replicated her pose, I could yield the same results. Preparing for sequence.”

Peridot laid down on the bed, positioning herself like the woman from the magazine. Her pussy spread slightly from the legs being apart.

Alright, legs are spread, now I just have to place my digits on…what is this thing a button?

She of course was referring to the clitoris that she hadn’t been paying too much attention too. Upon pressing down on it, a sensation similar to a small electric jolt shot through her body, aching even in her gem. She pressed on it again and again, beads of sweat forming on her cheeks and forehead, sliding down as she felt something building between her legs, inside her new vagina. Something soft and wet.

“R-Re-e-e-sul-uhts! Yielded indeed!” She said, “Still, not moistening or secreting, what am I d-d-oing wrong.”

She turned to look over at the opposing image in the playboy, a red-headed woman with comedically large breasts was pinching her nipples and smiling seductively at the reader.

“Perhaps pressing my chest buttons will yield the same results.” Peridot said.

She fondled one of her new bosoms with her right hand but kept her left on her clitoris, never stopping the pressure on it. Her nipple pressing yielded even better results than she expected, her mind became foggy, and her body temperature raised. She was used to extreme heat, but this was different, kind of intimate, loving even. Something was thumping, she didn’t have a heart, but she could feel something thumping in her neck and a voice telling her to keep going until she got what she wanted. What she wanted though was unknown to her.

“P-pr-e-e-ess-in-ing, down o-ah-on b-bre-ast bu-utt-ons, have y-y-y-ielded amazing results!” She struggled to get out, not even sure if the recorder picked it up, “Body temperature has risen and mind is going foggy, c-c-ca-an only f-f—fuck-focus on…pleasure…”

BWEEN!

The sound of the warp pad rang in Peridot’s ear, cutting a dodgy path to her brain. Someone had returned, and depending on whom, Peridot may have found herself into a world of trouble.

“Oh, damn it, someone’s home!” Peridot whispered, “I have to stop but…I don’t want to…oh no! Why can’t I stop!”

“Peridot, is that you I hear?” Garnet asked, walking up the stairs.

“Oh crud, not the Garnet!” Peridot whispered to herself, though secretly she was glad it wasn’t Pearl or Steven.

“Peridot is everything o…oh…” said Garnet once she reached the top of the stairs and saw her naked former enemy in the middle of the self-love.

For what seemed like hours but was only a handful of minuets the two stared at each other. Peridot’s face making one on the verge of tears and Garnets devoid of emotion as usual. This was the most embarrassed Peridot had ever been, even that limb enhancer incident on the lava colony was preferable to this. Peridot quickly removed her hands from her sex organ and breasts and clasped them together like an innocent schoolgirl.

“The Garnet!” She shouted, her face flustered, the pleasuring effects from the masturbation fading, “I was…I was just doing some experiments with myself and I—”

“You’re doing that wrong.” Garnet interrupted.

“Huh?” Was all Peridot could muster, not expecting this result from Garnet at all, in fact she was most expecting a very violent response from the fusion.

“An experiment like this is better performed with a partner.” Garnet explained matter-of-factly, “Would you like some assistance?”

Peridot was still confused; shouldn’t The Garnet be furious with such filthy acts? No. The Pearl was clearly the prude of the group, still while Peridot was pleased by the results she wasn’t getting where she wanted. Peridot picked up the Playboy and flipped over to a page which had two women, grinding their pussies against one another.

“Well, this next one does require a mate.” Peridot said, not noticing the purple light from Garnet flashing in her face, “Would it be too much trouble to…oh…oh my…”

Garnet had already taken the initiative and made herself nude. Her large butt the same size but her normally small chest sporting quite the lovely and plump pair of tits. Complete with burgundy areolas and nipples. A slightly bigger vagina between her legs and a cocky smile on her face sent chills up Peridot’s light spine.

“Ah! I see you are familiar with this process.” Peridot stammered. “So please, tell me what is the purpose of the fluids in the vagina? If you don’t mind of course.”

“It’s a natural lubricant.” Garnet said, crawling on the bed, “It makes this experiment a lot easier.”

Peridot was going to question her further when she realized, too late of course, that Garnet was already negligible kilometers away from her. Her massive bosoms just above her stomach. A sensation of fear, similar to a lamb being cornered by a wolf erased any effects the masturbation had on Peridot, the smile on Garnet’s face came across as threatening rather than seductive. Garnet removing Peridot’s visor didn’t help. As quick as a flash, her fears were replaced with mild confusion as Garnet planted a forceful but tender kiss on her green lips. She could feel something licking away at her lips and teeth, like a worm trying to dig through tough dirt. Curious she opened her mouth just a little and was immediately attacked by Garnet’s tongue, wrapping itself around Peridot’s and lulling her mind to an ease. Peridot’s eyes bucked open when she felt something penetrate her pussy, it was Garnet’s left middle and index finger going full force, the liquid she so desperately craved finally secreted, rocking her tiny body, and giving her a sensation, she hadn’t felt before.

Ah! Yes, this is much better with a partner, I should’ve gone to the Garnet with my curiosities beforehand. I should take her up on her offer to fuse next time the occasion rises, as for now…I need more data!

Garnet finally broke the kiss, hot breath and saliva leaking from the two as they panted and tried to regain their composures.

“I see what you mean now!” Peridot said, “I wasn’t doing it properly, and thanks to this fluid your touch-stumps can pass through without any difficulty!”

“That’s not all that can pass through.” Garnet said, taking the playboy and turning the pages until she found an image of a human male, standing over a blonde woman, dick rock hard and ready to bust as she kneeled with her mouth wide open, “See this thing on the human male?”

“Oh yes his…dick I believe its called.” Peridot said, in awe and fear of it.

“Yes, now see this.” Garnet said, pointing to a picture of a man on his knees, pounding away at a woman on all fours.

“Oh yes that is an interesting position.” Peridot said, she was confused as to why Garnet was showing her all of this, she was sure Garnet didn’t like males, “Is there a way we could procure a human male for this experiment?”

“No need.” Garnet said, a dark purple light emerged from her crotch, in an instant her replicated vagina transformed into a five-inch replicated dick, thick and bulging with fake veins.

“Oh, my stars that’s incredible!” Peridot yelped in awe.

“Allow me to enter Peridot, and I can give you data you’ve never even dreamed of.” Garnet said, the fake phallus twitching in excitement.

“Well of course Garnet!” Peridot said smugly, “Our transformative powers just go to show how superior our race really is. Poor humans.”

Peridot laid back and spread her legs as Garnet straddled just above her, lining the imitation dick with her pussy.

“Before I do this, just let me know if its too much.” Garnet said, “I wouldn’t want to hurt you.”

“Uh, yes, I’ll be sure to let you know Garnet.” Peridot said, now feeling a bit nervous and yet she was more than ready to receive, just feeling the large tip from Garnet’s phallus was making her eager from more.

This eagerness was rewarded and then some when Garnet inserted herself inch by inch into Peridot, filling up her fake womanhood with the dick, eliciting little adorable yelps and mewls from the tiny gem. Her massive bosoms almost swallowing Peridots. The sensation of being filled up caused Peridot to shiver and squirm like a naked person in a snowstorm. Peridot’s pussy was certainly different from any Garnet had before, moist, tight, and begging for more. But it was her first time and Garnet didn’t want to hurt her. Too much anyway.

“G-G-Garnet I—”

“Its okay Peridot…I’m here.” Garnet said, giving her a reassuring kiss on the cheek.

It took a minute, but Peridot had finally calmed down enough to stop twitching, her body adjusting to the feeling of having the phallus in her and begging for more.

“N-Now what?” Peridot asked, “Do you just let this thing gestate in me?”

“No, now I do this,” Garnet said, giving Peridot a weak thrust, just enough to get an ‘Oh my!’ out of her and make her shiver again, “you see I thrust in and out of you, stroking you with this dick until we both climax.”

“C-C-Cli-max?” Peridot said as Garnet continued the slow, teasing thrusts.

“Yes, you’ll find out soon enough cutie.” Garnet said, flipping through the Playboy, “Now let’s try something new, I think you’ll like this.”

Before Peridot could ask, Garnet stood up, scooping her in her arms, still never taking the dick out. As soon as Garnet sat down, she spun Peridot around until she was facing away from her, causing the clutching feeling in her light stomach to increase and squeeze down on Garnet’s phallus, which in turn caused her fake balls to tighten. Garnet grabbed Peridot’s legs and lifted them above her head, clasping her hands together in a full nelson behind Peridot’s head.

This feeling of helplessness increased the excitement for the green gem as Garnet thrusted faster, pounding the tip repeatedly into Peridot’s gemhood. She couldn’t even form words just moan and pant as she was taken for a ride, the only disappointing thing was she couldn’t feel all of Garnet’s cock inside of her and she really wanted the data on that. Her wish was granted when Garnet let go of her legs and laid back.

“Turn around.” She ordered, to which Peridot obeyed.

Now feeling the full girth of Garnet inside of her, a small trail of gem drool leaked from Peridot’s mouth as she grabbed a hand full of Garnet’s tits. Garnet placed her hands on Peridot’s hips and lifted her slightly, performing the same grabby motions on Peridot’s ass as Peridot was doing to her chest.

“This one’s called cowgirl.” Garnet said in between pants, “You’ll like this one, since you’ll have to do most of the work, you just bounce on the dick until your heart’s content.”

“First we don’t have hearts!” Peridot said, semi-lost in lust, “Second, I understand the basics of this, though I don’t know what cows have to do with it.”

Peridot did as instructed, lifting herself up and lowering herself repeatedly onto Garnet’s rod, moaning and whimpering whilst holding onto Garnet’s stomach for dear life. Peridot was so tight Garnet was worried she may never be able to dislodge herself from the poor little thing. Not that she would want to, she thought in the back of her head, squeezing onto Peridot’s ass, and giving it a light slap here and there. If this continued to go smoothly Garnet made a mental not to show Peridot the pleasures of the back door sometime. Peridot’s muggy vision fixated onto the Playboy once again, this time onto a very interesting position, one where the female was bent over, getting pounded by the man.

“G-G-GA-Ga-ga-r-net!” Was all Peridot could say as she pointed to the page.

Garnet nodded in understanding and scooped Peridot in her arms, removing herself only temporarily. She placed Peridot on the bed, bent over the edge with her feet touching the floor. She placed her hand on Peridot’s back and reinserted herself, slowly, inch by inch again, then began thrusting vigorously. This position the sensation of having her thick cheeks slammed while Garnet pounded her gemhood was the absolute best.

“Being filled with this…this…dick! It’s the best!” Peridot screamed.

“If you think this feels good,” Garnet said, slapping and squeezing her right ass cheek, “Just wait till I fuck you here.”

Peridot couldn’t hear her; she couldn’t hear anything but the sounds of her own intense panting and wailing as Garnet pounded her. Words failed to form the only thing she could mutter aside from the grunts was Garnet’s name and ‘Yes!’ which she squealed endlessly. Garnet reached around and pinched Peridot’s clitoris sending one final wave of ecstasy across her body.

“M-MY BUTTON!” She yelped.

“For future references, getting touched right there after getting fucked for a long time, best feeling there is.” Garnet said as Peridot finally climaxed all over her fake cock.

Garnet also reached her climax, twin streams of thick, clear fluid leaked from their replicated organs, leaving a small puddle of slime at the base of the bed.

“You did very well, cutie.” Garnet said, giving her a kiss on the cheek, then placing her on the pillow to rest up.

“I’ll require further testing for this experiment,” Peridot said in a post-coitus haze, “MUCH more testing.”

“I think next time I’ll show you how to use your mouth.” Garnet said, cleaning up the mess they left.

Peridot grabbed the Playboy and turned to an article that said, Milfs vs. Cougars: How to know to know the difference and which one is truly the best!

Hmmm, I wonder if the Garnet counts as a Milf or Cougar.
