Homology

Ellie rose on her knees, stretching up to the height Maud would have been had she been standing up. Placing both shins on either side of Maud’s torso, Ellie straddled her belly, her knees on either side of Maud’s head. She noted with delight Maud’s muted surprise at just how long the human’s limbs were.

Reaching underneath herself, Ellie found Maud’s erect clit with her hand, and slowly guided herself down until she was right where she wanted to be, her lower lips pressed against the base of Maud’s shaft.

She concentrated on the feeling of Maud against her, the warmth of her flesh against hers. She gently pressed upwards on Maud with her fingers, and began to rock herself against the base of Maud’s clit. She sighed contentedly, then began to slide back and forth, spreading her slick up and down. Finding equilibrium, she closed her eyes to focus on the sensation of Maud’s shaft sliding against her.

“Oh, wow, that feels nice!” Ellie bit her lip as she looked down at Maud’s face, which was as expressionless as always. “How does that feel?”

“Soft. Not like a rock.” Maud said. Ellie could see a tinge of blush on her cheeks. “It feels good.”

Laughing at that, Ellie bent over to kiss her, supporting herself with an elbow at the side of Maud’s head. Her lips met the mare’s, forming a second connection to complement the one they had below, incarnating a non-trivial class in the first homology group. Maud’s lips were so wonderfully soft.

Ellie rocked her hips forward, until she could feel the ridge of Maud’s medial ring cross her clit. She then rocked back, feeling the ring press up deliciously against the base of her clit before sliding smoothly over the head. She rocked forward again, then back, then forward, then back, finding surer and surer footing in her movements as Maud’s ridge massaged her clit over and over again. A shudder built, then released itself, causing her to roll her neck as it worked its way down her upper back. She paused, her clit and lips pressed firmly against Maud’s shaft as she held herself stiff, letting the shudder work itself through. She broke her kiss and exhaled nervously, the sound turning into an odd squeak.

“Wow! I…”

Ellie still had her eyes closed. She concentrated on how Maud felt on her. The warmth, the fullness, the thickness of her clit something that she was holding on to, hugging.

“Wow.”

Feeling underneath herself, she could see how good of a job she had done in glazing her. She smiled contentedly. She opened her eyes to look into Maud’s, big and beautiful and expanding across her vision. She then looked down the space between their two naked bodies, finding it cute how the top quarter of Maud’s clit was protruding from the light tangle of her bush, almost as if it were her own…

Well, that’s something to file away for later.

She looked back into Maud’s expressionless eyes. They were just so pretty. She kissed her deeply, focusing this time on how her lips felt against her lips. How her tongue felt against her tongue. How she kissed back with an unmuted passion. When she broke that kiss and looked into her eyes again, they were the same expressionless ones as before.

Ellie sighed softly. “I feel close to you.”

“I feel close to you, too. We’re touching each other very intimately.”

Ellie could not argue with that. She was about to say something when Maud continued.

“I know when I say things sometimes, it’s hard to tell that I’m being sincere. I want you to know that I really mean it. I really feel close to you.”

Ellie’s heart melted at that. “I know, Maud.” She kissed her, and smiled, tangling the fingers of her supporting arm in her mane. “I know.”

She kissed her deeply again as she inched herself forward even further, until she reached the ring encircling the head of Maud’s clit, itself ridged around with the spongy tissue that would expand taut when it was time for her to flare. Ellie broke her kiss and bit her lip as she remembered the delight she had felt in discovering that for the first time.

Using her hand, she drew against herself with the tip of Maud’s clit, tracing circles that pressed down one lip, both, then the other, before massaging the nub of her own clit at the top. She dragged the edge of Maud’s clit across herself slowly, feeling every cell of that delightfully yielding gray surface. Circling, the sound and feeling of flesh sliding against slick flesh, circling. Wide ones at first, then tighter and tighter, zeroing in until…

“Ack!” Ellie cried out in her best Cathy impression, before flopping over to the side very un-sexily. “Oh wow, sorry!” She tried to quickly recover, getting back up to assuage a concerned-looking Maud, who had sat up. Ellie felt touched that it was one of the rare times she had seen Maud’s eyelids form anything other than a flat semi-circle.

“Sorry!” She found Maud’s clit again with her hand, and kissed the tip of her sweetly with her mouth. Said sweet kiss transformed into a lingering one as Ellie’s tongue rediscovered just how nice the soft, gray flesh of Maud’s clit felt against it, and a small moan escaped her lips before Ellie realized what she was doing and opened her eyes. She looked up at Maud, who was looking down at her with those same half-lidded eyes again.

“Sorry!” Ellie said a third time after popping Maud out of her mouth.

“I don’t think you did anything wrong.” Maud said. “Did I do anything wrong?”

“No, no! I mean, we never talked about this! I, uh, I guess I got carried away.” Ellie bit her lip and looked away for a second. “I, uh, I don’t get penetrated?“

“Oh. I’m sorry I let it get so close.”

“No, no! It’s not your fault! I, uh… Like I said, I got carried away. I just…” Ellie laughed at the ridiculousness of it. “I, uh… Back where I’m from I’m usually the one doing the penetrating, so I, uh, I’ve never been, and at this point I’m not even sure what the line between ‘won’t’ and ‘can’t’ is? I’m sorry, it’s hard to explain.”

“You don’t have to.” Maud said. “I just want to know what you want to do, and what you don’t.”

“I mean, that’s the thing! I…” Ellie laughed again. “I want to. But, uh, I might have to work my way up. And, uh…“ She held Maud’s hoof. “Wow. What a self-discovery to make after being zapped into magical horse world,” she muttered without realizing.

“Oh.” Maud put two and two together quick, to Ellie’s dread. “If I were a unicorn—”

“No!” It was Ellie’s turn to shove her hand in Maud’s muzzle. “No. You are perfect. You are Maud Pie.” She removed her hand to kiss her.

“It’s nice like this, you know? Earth pony. Earth human.”

Maud smiled.

“Besides! I have my own fingers.” She considered them in front of her, then frowned at realizing how many she would need at once to prepare for Maud. “I could work my way up… Slowly…”

She turned to Maud, and wrapped her arm around her, holding her close.

“Is that something you’d want?”

“I want to do the things you want to do.”

“No, I mean…” Ellie had to stop herself again from laughing again at the ridiculousness of it. “Do you want to be inside me?”

Maud’s cheeks tinged as she looked into Ellie’s eyes. “Yes.”

A shiver ran pleasantly through Ellie. “Oof. Is it weird that I find that hot, even though I’m not even sure that I want to do it yet?”

“I don’t think it’s weird.” Maud said. “I just like being close to you. It’s another way to be close.”

Ellie chuckled. “And that’s all that has to mean, huh?”

“Does it have to mean anything else?”

“No.” Ellie smiled. “No, it doesn’t.” She kissed her deeply, slowly lowering Maud’s body back down to the bed as she did, her left arm wrapped around the back of her head. With her right, she caressed down her body with her fingertips until she found the length of her clit, and began to stroke her with her fingertips as well. She caught Maud’s moan in her mouth, then broke her kiss, and smiled.

“Speaking of other ways to be close…”

She lowered herself down Maud’s body until her face was in position. She kissed the tip of Maud’s clit, then sucked the first half-inch or so into her mouth, her lips opening wide to take in her girth. She began to massage her with her tongue, enjoying the tastes and textures of the surface of her clit-head, from top to bottom and all around her sides. Ellie delighted in the feeling of Maud stiffening in her hands, as she inched her face forward on her shaft.

More of Maud filled her mouth, pushing her to loosen her jaw muscles and tongue as much as she could to take in more of her. More and more, until she felt the soft ridge of Maud’s clit against the soft palate at the back of her throat. She could only breathe through her nose now, every breath she took causing her to feel the sheer lack of space that was left in the cavity of her mouth. The sensation of being so filled-up was exhilarating. With her lips extended, she could just about feel the border of her medial ring. That there was so much more Maud to go…

She closed her eyes, filled her lungs with air, and lurched forward.

Maud’s clit filled more of her, pushing her way past her soft palate and properly into her throat. Ellie shallowly bobbed up and down, working Maud deeper into her body still. Past the point that seemed possible. Her diaphragm tentatively tried to expand, then found itself fighting against hard vacuum. Her airway was blocked.

Her autonomic system woke, and began to jam down on its alert buttons, sending red-letter warning after red-letter warning to the conscious part of Ellie’s brain. The conscious part of Ellie’s brain was giddily laughing at this, happily signing off on said warnings. Yes. She agreed completely. The thing lodged in her throat was very important and she should pay a lot of attention to it. Yes. She thanked her autonomic system for also really being into Maud’s clit like that.

Her brain then helpfully began to shrink the entire universe. The borders of the world available to her conscious mind contracted as she yeeted herself down Maslow’s hierarchy of needs, hit the ground floor, and kept digging. The only thing that existed in the universe was what was preventing her from breathing. The inches of flesh jamming her throat were the entire universe. Maud’s clit was the universe. The only thing that mattered. The only concept to exist.

It was very hot.

She felt the edges of her cognition slip away. Through the murkiness, she felt a disturbance. Maud was pulling herself out of her throat, the seal releasing itself with an internal pop. Her autopilot immediately gulped down a breath through her nose, and her world expanded again. Part of her wanted to protest, but felt weird about that, and meekly let Maud pull herself completely out of her mouth. She stretched out her jaw and gagged and gasped for air, and felt the tears that were streaming down her face for the first time.

Maud’s clit was still in front of her, damp with her saliva. She felt an odd sense of achievement in just how far down her shaft the glistening had reached. A sense of disappointment at the length that remained untouched.

She looked up at Maud through tear-rimmed eyes, who was sitting up again and looking down at her with more of that rare displayed concern, her eyeshadow no longer visible.

“Ellie.” Maud said. “Please don’t choke yourself to death on me during sex.”

Ellie laughed, fighting the urge to blurt something about how great of a way that would be to go.

“Okay. But before the choking myself part, did my throat feel good?“

Maud reddened, and didn’t answer the question.

“You made me worry.”

“Oh, Maud.” Ellie raised herself up to kiss her, then wrap an arm around her neck. “I’m really sorry. I got carried away again. I, uh, I really need to control myself.” She kissed her again. “I’m sorry. It won’t happen again. I don’t want to make you worry. Just relax.”

She guided Maud’s body back down onto the bed, then kissed her reassuringly a few more times, continuing to whisper gentle nothings at her until the concern on her face was replaced by a slight smile.

“Just relax,” she said again, as she brought her face down Maud’s body once more. She massaged her hips and flanks reassuringly, looking up at her and smiling.

“My throat did feel good though, right?”

Maud blushed, and looked away, finally admitting it. “Yes.”

Another shiver shook Ellie, and she instinctively reached down to begin massaging her clit. As she did so, she wrapped her lips around Maud’s clit again while wrapping her other hand around her shaft. Deliberately drooling out some excess, she began to use her extra spit as lube, but found that it did not seem to quite be enough. So she switched hands, contributing the slick that coated the fingers of her right hand to the mix, which was enough to begin to comfortably tug Maud up and down. She was better with her right hand anyway, because she is canonically right-handed.

Bobbing her lips up and down in an opposing cadence with her hand, she began to vary the length and speed of her strokes and bobs, pausing at the ends before lusciously and lovingly stroking back to the middles. Maud’s soft moans were both feedback and delicious stimulus of its own, as Ellie began to stroke herself to them as well. Slowly, slowly, the moans built up, and Ellie controlled the burn rate on her end as well so as to not outpace the beautiful mare she was pleasuring.

After some time, the moans turned into heavy breathing, and Ellie could feel a sense of accomplishment as she began to taste the lube that Maud’s clit coated herself with. She quickened her pace for the home stretch, and her eyelids fluttered as she felt that wonderful flare against her tongue, preceding the pumps of liquid that filled her mouth to the backdrop of that beautiful dulcet tone of Maud’s climax. Maud’s pleasure pumped and pumped, hot and salty and pungent, with just a hint of grassy undertone. Another preshock rippled through Ellie as she sucked up Maud’s last echo of a pump, then popped her out of her mouth and lovingly licked up the last droplet still clinging to her head by surface tension.

She kept working herself as she extended her body to lie down next to Maud, leaning into the valley of the preshock. She focused on the sensations of her fingertips against her clit, the taste and texture of Maud’s cum sliding down her throat as she swallowed up her mouthful in tranches, the smell of saliva and sex, the sight.

Maud’s beautiful face, dominated by the two pools of her closed eyelids. Her face flushed, serenely smiling as she continued to gently undulate and shake in pleasure. That smile. So gentle. So rare. So vulnerable. Those eyes. Opening up slowly. Looking into her own. So brilliant. So filled with soft affection. With love.

Her back bent, driving her shoulders and hips into the surface of Maud’s bed as the first wave overtook her. Pleasure radiated from the core of her being, obliterating the internal divisions she felt in her structure as her muscles contracted. Then released, rounding her spine and her shoulders forward again. Then contracted, as a second wave hit.

As she came down, Ellie realized that Maud was embracing her to her, holding the length of her naked body against her own. Ellie wrapped her arms around her, and held her close, contracting into her as they locked lips. As she felt the warmth of her skin through her coat, she imagined the surface of their bodies joined into a single, tranquil ocean, occasionally disturbed by the ripples set forth from a hidden sea mine. Those waves had done more than just pass through her. They left little pools of themselves embedded throughout her body, to burst and fill the rest of her with echoes of pleasure from a shoulder, or a spot on her neck, or a rib. She felt occasional squirms from Maud against her, as well, and tasted them against her body.

Her burning interior settled into a pilot light, still burning, faintly. Warm and fuzzy, increasing the sensitivity of her touch, causing her to feel so close to the mare whose soft, warm body she was holding against her that it felt as if the core of their beings were joined.

Looking into those shimmering turquoise eyes, reflecting that warm smile back at her, Ellie knew, despite the impossibility of knowing another’s qualia, that Maud was experiencing what she was, in all of its incommunicable depths and subtleties. Ellie was so very glad.

Because there were only two things in the human experience that transcended the cold realm of the material and the unfeeling logic of evolution both: pure mathematics and the female orgasm. Ellie was so very glad she could share both with Maud today.

They kissed, embraced, and held each other tight until the very last embers of their orgasms gave off the very last of their heat, and continued cuddling for a good while afterward as well.

Life was pretty good, all things considered.
