Warning: This story contains Gem x Male sex and romance. This story features gem penetration. The gem in question is replacing one of the eyes of the particular Gem.

Synopsis: Squaridot has been dating a human man named Kane for a while. They have a lot in common, and are very much in love. They have also had sex in the past; which Squaridot has taking a liking to. While researching fetishes, she realized she has a fetish for putting things inside her Gem. She had always assumed the pleasure she had felt storing things in her gem was an issue with her; now she knows better. She decides to be honest with her boyfriend about her desire to explore this newly discovered kink. Her and Kane go on a date, and, when they get home, she tells him of her desires. He accepts her, and agrees to give it a try. They have sex, and both enjoy themselves. In the future, they get married. The title is a pun on the fact that Squaridot's gem is in her eye, and so Kane having sex with her gem is technically... well, skullfucking.

Oneshot

-----------------------------------------------------------------------------

Squaridot couldn't believe how far she'd come. There was a time not so long ago where the idea of living on Earth seemed anathema to her. Then she found the courage to give life on Earth a try. Then she went to a party with her comman... Ex-Commander Hessonite. And at that party, she met... him~. His name was Kane. and he was gorgeous and so intelligent. No human she's met before or after she met him has understood even the slightest bit of Gem Tech. No human has ever understood Gemmetic theorems before or since. His sexy, brilliant mind drew her in... and his boundless generosity and kind heart hooked her.

Oh, by the Diamonds, she was in love.

His gorgeous golden locks, his cute facial features... the feel of his lithe body against hers~. She had looked into human courting and mating rituals and well... sex at first seemed like such an inefficent method of reproduction. Then she tried it... and a lot of things about human courting rituals made way more sense!! It felt so good~!! And the idea that part of why it was so satisfying was because of her feelings for Kane was not lost on her.

Ever the inquisitive type; as is the usual for Peridots; Squaridot looked into more and more of this "sex" thing. She wanted to know as much as possible, both for her sake, and Kane's. Recently, she's learned of something known as "fetishes". It is when something not explicitly sexual causes sexual excitement. For example, many humans find sexual excitement from feet. While, academically, she understood the concept perfectly, she didn't grasp the why... that is, until, she tried to apply it to her own experiences.

Nearly every Gem can store things inside their Gem (Pearls are merely the most well known for it, but any Gem can do it.) And... everytime she does... there's a... thrill to it~. It feels so good. She thought it was a reward system for storing objects efficiently implanted into her programing but none of the Peridots she mentioned it to felt the same. Even most Pearls she talked to hadn't felt the same. She'd always thought it was a bug in her programming... now she finally knew! She had a fetish for things going into her Gem!!

She thought about Kane... and, more specifically, about his thick, meaty, reproductive rod~. His shaft, his penis, his dick~. That long, hard pillar of pleasure has brought her to completion many times with only traditional human reproductive methods. What if... what if they had sex... with her Gem~? The thought sent a delightful shiver of arousal throughout her whole body. She could feel her vagina moisten in arousal at the thought. Well... if just thinking about it makes her feel like this, she has to try it for real. Kane is understanding, and caring... so, she was only slightly trepidation about asking him to do this to her.

Kane, being the loving boyfriend that he was, had planned a date for them. And, judging by the cost expenditure of the date (that she calculated in her head; economics is so simple), it was not only intended to be highly romantic, but also it was going to end in... sexual intercourse~. The thought of making love to Kane made her Gem pulse with a base delight. Stars, she loved him so~... But, the heady romance in the air, and the sexual tension that would build up on the date made the ending the perfect time for her to ask him to... well... make love to her gem.

She (with some effort) shifted a dress that her research had told her was "fashionable" and "beautiful" by human standards. She had to admit, it did show off her curves in a delightful fashion. With her limb enhancers all tuned up and ready, she headed out to meet her... Boyfriend. (Just thinking about that made her all giddy. One day, their courtship will be complete and they will be "married"! She giggled to herself like a nerd at that thought, before composing herself.)

She hitched a ride over to the restaurant that he had made a reservation at. Pricy; one of the most expensive in Beach City (which made it moderately priced by the standards of the larger cities). While she didn't need to eat, nor did she really care for the ambience of most places, the fact that Kane was willing to spend so much of a precious resource ("Money") to impress her or to give her a good time made her feel warm and fuzzy inside. It showed that she was something worth spending resources on; something she's... never experienced before. She's never been that important. The greatest of Peridots is still beneath many, many different Gems.

"Hey, Squaridot~, glad to see you could make it." Kane said. At first, when it was a moniker that vexed her. But as the months rolled by, she grew to like it more and more. But when she told Kane that nickname, and he called her it as a term of endearment? Oh, she fell in love with it! Now, she prefers the moniker 'Squaridot' to her real Gem number identification serial! She responded to the wonderful man in front of her. "Y-yes, I wouldn't miss it for the world."

The restaurant was nice, as to be expected. It was an italian restaurant, and, as befitting it's "high class" nature, the decorations were authentic and pleasant on the eye. The smell of garlic and pasta sauce filled the air and tempted the appetite. Squaridot was unimpressed, as most of the instincts that the sights and smells were supposed to tempt were absent in her species, though she was tempted to eat, simply by conditioning from previous dates. She wrapped her arms around Kane's, as he led her to their reserved table.

She ordered some pasta dish that sounded fascinating, he, meanwhile, ordered like he had been planning what he wanted for quite a while. As they waited for their food, they made small talk. Mostly nerd things. Computers, advanced tech, that sort of thing. As the appetizers arrived, they had transitioned to talking about Gem/Human relations; both political and interpersonal. By the time their entrees had arrived, they had transitioned to talking about... themselves.

As they ate and conversed, both Squaridot and Kane swam in the love for one another they felt. Anyone that looked in on them could tell they were perfect for each other. Two geeks in love. How wonderful. As they talked, Squaridot's thoughts started to turn more... Amorous~. And those delightfully romantic thoughts reminded her of her examinations into the concepts of fetishes earlier that day. And she decided to brace him for impact.

"Kane... later on, I... I want to try something new... if that's ok." Squaridot asked trepidatiously. "Of course it's ok with me, Squaridot. I'm always down for trying new things." Kane answered honestly. Squaridot thanked him, love thick in her tone. He was as inquisitive and eager to experiment as she was, just another thing that made them perfect together.

They finished up and Kane paid the bill (Squaridot had yet to figure out the "application" part of job seeking. Not being a citizen of... Earth made it even harder to get money.) They walked out to the Beach for a pleasant walk to help digest their food before they went back to Kane's house (Squaridot couldn't wait till they were far enough in their relationship that she could "move in" and live in his house; but for now, she was content to visit.) As they walked, she was arm-in-arm with Kane; simply loving in their closeness and the warmth of his body~.

As the walk ended, and Kane walked her to his car (a very sensible model, the kind an engineer would love), she was more than ready to feel him inside her~. She was feeling so aroused and "horny" that she was glad that he couldn't see her inner thighs through her dress; they were kinda soaked with her natural lubrication. As he drove them to his house, she went over what she was going to ask of him in her head. She was so eager and tense for... making love to him~. She bushed a vivid green as she thought on this. She couldn't wait for it~.

He drove up to his house, and Squaridot couldn't help but feel her nonexistent heart skip a beat metaphorically. Soon, he would be inside her~; she was going to have sex with her precious Kane~!! They walked into the house... they walked up to his room~... And as he kissed her, and his tongue explored her mouth, she readied herself to ask him... to ask him to... make love to her gem.

As he pulled back, she shifted off her clothing, leaving her naked, and letting him see how wet She was for him. She could see the bulge his erection made in his pants, as he started to take off his own clothes. That's when she sprung the question. "Can you... make love to my Gem?" He stopped, his pants and underwear half off. She was salivating at the sight of it~. "Excuse me, what?"

She made her gem glow as she opened it to intrusion. "I... I asked if you would... stick your... p-penis inside my gem..." He gave her a weird look. "Would... that do anything for you?" He got an inquisitive look on his face; to Squaridot, it looked sexy~. "Well, If it'd the center of your being, the idea that it could act as an erogenous zone makes sense actually." Huh... she hadn't thought of that. This was yet another reason why she loved him; he could see things that weren't obvious to her. "So, to be clear..." He said, "You want me to 'skullfuck you?" he asked. "Technically." she responded. He looked at her, and said: "Alright, I'll do it~!"

Her non-existent heart skipped a beat! She couldn't have asked for a better response. She got on her knees and waited. "Well~? Go ahead, lover~." She said in as sexy a tone as she could. He walked over to her, and gently pressed the tip of his impressive cock against her gem. She shivered in anticipation... and then? 

His cock penetrated her gem~.

Her eye rolled back into her head, as a pleasure like she'd never experienced before crashed through her. It was like he was penetrating her soul~. He bottomed out against her gem, and she... she came. Right then and there, she squirted onto the ground, orgasming from him invading her most sacred of spaces, the interior of her gem~. 

He started to thrust against her, reveling in the tingling feeling of her magic against his cock. She however, was completely lost to the pleasure. As he used her head as a handle to thrust into her gem, she was in heaven~. A state of pure bliss, constantly in a state of orgasm, broken up by more major, actual full body orgasms that made her form glitch out from how powerful they were.

She moved her body in time with his thrusts, her untouched pussy squirting onto the ground as she was fucked into an orgasmic mess. More and more of her higher functions were shutting down to better process the pleasure she was feeling. It wasn't too long before he reached his limit. "I'm cuming!" He shouted.

He filled her gem with his precious seed..., and as he pulled out, she poofed into her gem from sheer pleasure overload.

She reformed in seconds, and quickly assuaged his fears for her safety... This was... the best she had ever felt. He told her "Well, that was... amazing but I prefer... your... ya know..." She understood. This was more for her sake than his. But she was glad that she had been open with him.

This set off a sort of "Chain reaction." He was more open with his kinks (he liked armpits... Weird but, hey, she wasn't going to judge the man she loved), and their relationship was much closer after that. A few months after Steven left Beach city... He proposed to her~. She said yes... and it was the happiest day of her life.

And now, Squaridot and Kane were married... and thanks to her being bold enough to be open with her desires, they were in an accepting, and very healthy relationship. Neither felt the need to hide anything from the other. She was truly happy.

The End.
