Work Text:
The door to operating room 5 swung shut after Doctors Mel King and Trinity Santos quickly shuffled out. The two stopped side by side just outside the room, where they stood in silent shock for a moment, with Trinity leaning against the wall casually and Mel hovering awkwardly by the doorframe. The scrubs of both were smeared with blood.
“Wow,” said Mel simply.
Trinity smirked. It was rare for Mel to be wordless. “Wow indeed,” she drawled.
“Wow,” Mel repeated. Of course, she didn't remain wordless for too long. “There are many different types of foreign bodies, with the most common cases being in children who lodge small toys, coins, magnets, or food into their nose, ears, or airway. As for adults, sexual gratification becomes a factor, so we see urethral and rectal self-insertion of objects all the way from household items like toothbrushes to…glass bottles…” She coughed. “Rectal foreign bodies, also known as RFBs, require urgent removal—whether it be manually with aid of endoscopy, or by surgical intervention, specifically, laparotomy or colostomy—in order to avoid serious complications including, but not limited to, sepsis, hemorrhage, infection, bowel obstruction, or, in severe cases involving sharp objects such as…glass…” She coughed again.
Trinity, who had been nodding along to the best of Mel’s womansplaining, found this to be a perfect place to butt in with a quip. “I guess this brings a whole new meaning to the phrase your ass is glass.”
Mel tilted her head and blinked, like a lizard shifting gears. “Huh…I've always heard the phrase said as your ass is grass.”
“Yeah, that's why it's a whole new meaning,” emphasized Trinity. She didn't say duh, but her voice was laden with it.
Mel opened her mouth briefly as if to respond to this comment, but Trinity could tell by the far-off look in her bespectacled eyes that her mind was still grounded in that operating room. “The combination of the colorectal perforation and the rectal lacerations caused such severe hemorrhaging…I can't imagine the pain. Worse, I can't imagine the shock when…”
“When, you could say, he cracked under the pressure,” Trinity supplied.
“That’s—” Mel began.
“Or shattered.”
“I—”
“Or exploded.” That one was a triple entendre. She was on a roll today. That was what a good old-fashioned sexually explicit injury could do for a woman.
The other reactions this could elicit from a woman were exemplified by Doctor King. Overthinking, empathy maybe? She wrung her hands together repeatedly, then persevered with her analysis. “The glass bottle was roughly twelve inches in length and five inches in circumference. I can't imagine,” she began slowly, “not only the physicality, but the mental willpower needed to control such an object. Any wrong movement could lead to disaster. Which it did. With that kind of pressure, it's no wonder our patient passed out…and when he hit the ground, the precarious frailty never stood a chance…”
Trinity felt a smug grin stretch across her face. Before she could stop herself, four dangerous words left her lips. “I could've taken it.”
Mel had long been accustomed to Trinity’s shenanigans by now, but the comment seemed to take her a second to process. She blinked. “Pardon?”
“I said…” Trinity instantly knew she had to double down—what other choice did she have? “I could've taken it.”
She turned to face Doctor King. The woman’s face was scrunched up. She pushed her glasses up her nose, then wrung her hands yet again. Trinity relished seeing her fellow doctor’s cool and calculated demeanor shatter just like glass, and she wasn't ashamed to stare into Mel's face, watching the cogs turn in her brain as she scrambled for an appropriate response to the inappropriate comment. Finally, after a few seconds, she settled on, “I'll take your word for it.”
“You don't have to,” Trinity blurted. She was letting her impulsive side take full control, and it felt good as hell. Maybe the sight of the glass ass had softened this part of her up—or, more likely, made her hard. “I can show you.”
Mel's eyes widened in horror, flickering back towards the operating room.
“Not with the bottle,” Trinity quickly clarified. “Or the exploding. Or the hemorrhaging. But—” At that moment, Princess appeared nearby, and Trinity made sure to lower her voice. “But I do have something glass. It's safe. And fun. If you know what I mean.” She leaned in close, trying to pull Mel’s mind out of the stupid manwhore’s ass and into her own.
It seemed to work; Mel's eyes were now looking in Trinity's general vicinity, and she was nibbling her lip. “I think I know,” she said. “You must be referring to a glass d—”
“Shh!” Trinity put her pointer finger against Mel's mouth. That woman had no filter, nor an inside voice, a deadly combination. Trinity glanced at Princess. Luckily, she still seemed to be busy with her chart, but it could quite possibly be an act. “I can show you,” Trinity repeated quietly, turning her full attention back on Mel, “what I can do. If you want that.”
Trinity stared into Mel's dark blue eyes, searching for any reason that she should back off, that she'd gone too far. Instead, unexpectedly, she found a glint. Mel looked intrigued, the same way she did when she got her hands on a unique patient.
“I do.”
Success. “Alright, then. Meet me outside the back door at 7. I'll give you a ride to my place. That's where the magic happens.” Trinity couldn't resist backpeddling for the pun. “Or, should I say, meet me in the rear.”
“Or you could say the behind of the building. Or its posterior end. Or the hindquarters,” Mel supplied from her seemingly-endless thesaurus of anal terminology.
“Now you're speaking my language.”
As Mel walked off, Trinity tried to flash a nonchalant grin, tried to prevent an anticipatory wetness from forming in her mouth or lower, but she didn't know how successful she was. There was something about Mel that could make the usual confidence she had with women waver. But nonetheless, she had her trapped now, somewhere she'd always secretly wanted Mel but never known how to achieve. And to think, she had Mr. Glass Ass to thank. As she headed back to her charting, Trinity couldn't help but hope that, after tonight, she would be the new notorious Glass Ass in Mel’s mind instead of that blubbering, incapable, idiotic man. She would show Mel how a woman could handle things. And once Trinity set her mind to something, well. You'd be an ass to doubt her.
God, she really was on a roll.
- - -
“Welcome to mi casa.”
It was about 7:40pm. As per usual, the day shift had gotten out a bit late, but Mel had been more than willing to meet at 7:20 instead of 7. Trinity had wondered if the car ride would be awkward or tense, but it had felt completely normal, with the two women talking about patients and their ailments and the like the whole way. In fact, this stream of conversation had continued all the way up three flights of stairs of the apartment building, and just as they reached the topic of the already-infamous Glass Ass, Trinity unlocked and swung open the door to apartment 308. She swept her arm outwards, much too grand a gesture for her small, messy abode.
“I like su casa,” said Mel, peering in from a respectful distance. Trinity held the door open and gestured (since when was she a gesture person?) for Mel to go in first—she wanted to show Mel that she came first in this situation. She stepped in. “It has a down-to-earth feeling. Like it's lived in.”
Trinity snorted. “That's one way to put it.” She headed in after Mel and shut the door behind her. “Make yourself at home,” she told her guest—they might call Trinity abrasive or challenging, but they couldn't say she didn't have manners—then went to set her bag down in the kitchen, muttering a curse at Whitaker under her breath as she stepped over a bag he'd left on the floor. Behind her, she noticed Mel surveying the cluttered room and tried not to feel self-conscious—fuck, self-conscious? Who am I, and what have I done with Trinity?
“You hungry?” Trinity called over her shoulder, rummaging through a cabinet. “Sorry, I usually just have instant ramen after my shift. You cool with that?”
“Yes! Ramen is one of my safe foods, actually,” chirped Mel. Trinity had already known that, of course, and had chosen it on purpose.
For the next few minutes, Trinity busied her body with preparing the food, and her mind with planning for what was to come. Lube, the leather harness, and of course, the star of the show… It turned out Mel had disrupted the shock factor of her plan, though; when Trinity popped back into the main room to ask Mel if she preferred chicken or veggie flavor (another question she already knew the answer to), she saw that the woman had discovered the special cabinet in the corner, and was bent over to rummage in it. Trinity approached her nosy guest slowly, silently, until she was nearly peering over her shoulder. “Look who spoiled the surprise,” she teased.
Mel jumped. “Sorry,” she said sheepishly, caught. “I just couldn't resist poking around a bit. My sister calls me a nosy Nelly.” Her eyes flickered downwards.
Trinity’s eyes followed Mel’s gaze. The open cabinet was the small-category one—but Mel didn't know that. Her eyes were trained intensely, hungrily on Trinity’s old six-inch glass dildo. Trinity couldn't help but bark out a laugh—she’d graduated that one years ago. Mel had no idea.
“What's so funny?” Mel asked. Trinity liked that unsure edge in her voice. She reached down over Mel's shoulder, making sure their arms brushed, and opened the other cabinet: the big-category one. She reached in and grabbed tonight's star of the show: a twelve-inch glass dildo. It was exactly the same length as Glass Ass's, but its added girth of six inches was a lot more impressive in Trinity's eyes, and she hoped it was in Mel's too. It was shiny, clear, hard, nubbed, and huge.
Mel's eyes seemed to be bugging out of her head. She was speechless again—hopefully not for the last time tonight. She reached out, as if almost subconsciously, to touch the glass.
But Trinity yanked the toy away before her guest’s hand could make contact. “Do you want your ramen first, or not?”
- - -
They'd had ramen first.
Now, they were in Trinity's bedroom. Mel, ever the helper, carried the dildo in one hand and balanced the leather harness and a bottle of lube in the other. Trinity dropped her scrub pants to the ground, giving the relief of freedom to her hot cunt. She didn't have to worry about underwear; she'd soaked through her only pair during her shift while thinking lustfully about her night with Mel. After shedding them, going commando at work had only turned her on more. She stood by the bed, waiting for Mel to see her.
But Mel, meanwhile, was distracted, and ever blunt. “Why don't you just keep all this in your room?” she asked, setting down the items on the floor.
“Oh, because Fuckleberry and I share them,” Trinity told her. “We're both too proud to let the other keep anything in their room, so the special cabinet it is.”
“Oh,” said Mel, voice a bit strained. “Do you take proper precautions?”
“Don't worry, he won't come in or anything. He's spending the night with the farm widow. Probably getting pegged or something. Do you need help with that?” she asked, as Mel had stepped into the harness and was trying to pull it up over her scrub bottoms.
“No, I got it. You just get into position.” Mel finally looked up, and her bespectacled eyes went straight to Trinity’s wet pussy. Her pupils immediately dilated. “Oh…wow,” she breathed. Trinity relished her stunned silence before Mel began filling it with rapid-fire words. “Your labia appears to have large inner lips, but I believe it's an illusion as your outer lips are small and open. Your vagina is lubricated by cervical fluids, which indicates sexual arousal, and—”
Mel's analysis continued, but Trinity started tuning it out, rolling her eyes lightheartedly as she hopped onto her king-size bed. She got onto her hands and knees by the pillows. Mel’s gabbing should've been annoying, but Trinity found herself endeared by it. Her fingers, which she'd already lubed up, gravitated towards her puckered asshole and circled the outside of it.
Suddenly, Mel, moving with more quickness than Trinity had ever seen from her, even during peak rush at the pitt, hopped onto the bed. She stood up on her knees between Trinity’s legs and asked, “Could I help you prepare?” Her voice wavered a bit. “It's ok if not, I just—”
“Of course.” Trinity craned her neck to look back at her guest. When she made eye contact, she found herself endeared yet again. Mel was wearing the leather harness, but hadn't attached the dildo yet; she'd set that, along with the bottle of lube, beside her on the plush bed. Mel's hands tentatively placed themselves on Trinity's cheeks. She still had her glasses and clothes on, but one thing was different: she'd let down her hair. Trinity had never seen Mel's hair down before. It was pale brown and fell in soft waves on her broad shoulders. The locks framed her flushed, smiling face perfectly. Trinity quickly turned back towards the pillow to hide that her usual smirk had morphed into a real smile. “I'm ready whenever you are.” She wanted the power in this situation, as she always did, but she found herself giving into Mel in ways she'd always craved deep down, even if it made her a bit unnaturally flustered.
“Do you have a safe word, Trinity?” Mel asked.
Trinity didn't particularly think she needed one in this situation, but nonetheless, her mind raced to think of something. “Uh…bradycardia.” The word for a slow heart rate. Because if Trinity’s heart wasn't racing, it meant that something was sorely wrong.
“Thank you. I'll start off by massaging your buttocks as a form of foreplay.” Mel did exactly that. Trinity was never a huge fan of foreplay—she liked getting straight into the action—but she appreciated the thought, and she let out a few moans of encouragement as the soft skin of her cheeks was fondled expertly for a few minutes. She could admit that the pressure and skin contact were nice.
“Now, I'm going to apply a generous amount of lube to my fingers.” Trinity could hear her doing so, and the wet sounds made her salivate in anticipation. “I'll gently insert my pointer finger into your anus. Are you ready?” Mel asked. Trinity growled a fuck yes—both her cunt and mouth were so wet they were dripping—and Mel penetrated her with one fingertip. Trinity let out a gasp. Mel’s finger had short nails and was slick and soft. She eased further in slowly, as if Trinity was a frail newbie, but she was seasoned, and her asshole was more than ready. After a few painstakingly-slow moments, Mel picked up the pace a bit; she stuck her finger deeper into Trinity, still narrating everything she was doing.
“My finger is in to the first knuckle…I feel your external sphincter…I am applying pressure to the muscle…I am inserting my finger deeper…My finger is in to the second knuckle…I feel your internal sphincter…I am applying pressure to the muscle…I am inserting my entire finger…I'll start to thrust my finger in the rectum…”
With each action, Trinity’s breath became quicker and quicker, and she reveled in the sensation of her asshole belonging to Mel. The finger was careful and practiced, and it didn't seem afraid to explore Trinity’s inner walls. She shivered as her rectum was thrusted into and tickled, deeper and deeper; Mel clearly had some experience here. But it was slow, and eventually, Trinity found herself aching for more.
“Insert another finger into me and curl them,” she instructed, unable to keep her wants inside any longer. “I like the way you're thrusting; do that again once both fingers are all the way in. Keep talking, too, but whisper into my ear.”
“Can do,” exclaimed Mel. “I mean…” She leaned in close to whisper quietly in Trinity's ear. “Can do.” Trinity liked giving commands, and she liked an obedient girl. Mel was quick to insert another finger into Trinity’s hole, which clenched around the digits. “I’m slowly inserting my middle finger deeper to match the depth of my pointer finger…now I’ll curl both fingers against the internal sphincter…now I'll repeat the motion…”
Trinity’s ear was tickled by Mel's hot, whispery breath and her soft hair. Mel's words became slowly indecipherable to her brain as she was overcome by pleasure; her hands dug into the sheets, and a strong whimper escaped her throat. Mel switched expertly between curling and thrusting. Trinity felt herself being loosened, spread, from the inside out, and it was perfect.
Before she knew it, she was demanding more, sounding a little needier than she'd intended. “Another finger…”
“Of course,” Mel breathed. Her lips were now fully on Trinity's ear, and she slid another wet finger into the woman's pulsating anus. Trinity murmured nonsensically as she was met by Mel's now-familiar monologue yet again. “I'm inserting my…” The whispers became white noise as she rode the three fingers in waves. Every muscle trembled as it felt pressure, and Mel's fingers crossed and uncrossed within her. “I'm thrusting…” Trinity gasped as the fingers penetrated her impossibly deeper. She felt her walls clench and quiver. Tendrils of hot pleasure radiated straight from her anus to her g-spot.
“Fuck!” Trinity gasped as, controlled like a puppet by Mel's fingers, she reached her first orgasm of the night.
Soon after, her walls relaxed, and Mel carefully removed her sopping-wet fingers. Trinity felt that familiar post-fingered looseness, and she bit her lip in satisfaction. It was rare for Trinity to give compliments, but one escaped her lips before she could help it. “Fuck, Mel, that was…great.” The pleasurable aftershocks left her craving more, and her asshole already felt unnatural in its emptiness. “I'm ready for the glass.”
“Already?” Mel questioned. “The average refractory period after orgasm for females is fifteen minutes.”
“I said, I'm ready.” Trinity tried not to snap, but a harsh edge attached itself to her voice. It had felt good, great even, to let Mel take the lead during prep, but she didn't want the woman to get used to it. This was Trinity’s realm, and it was her own dick she was about to be penetrated with. And she was damn good at it. She would show Mel. She would make her forget every single fact she knew.
Mel didn't seem to pick up on Trinity's newfound intensity though. She continued talking as she attached the glass dildo to the leather harness, then covered it in lube. “Lubricant is essential in sex, especially anal sex, because neither the anus nor the rectum produce natural lubricant. It prevents friction, which—”
“Mel.” Trinity cut off the woman harshly, whipping her head around to face her. She was annoyed, but she softened a bit upon seeing her guest's innocent, confused brown eyes behind her iconic glasses. It was just Mel. “How do you know this much about sex?” she decided to ask.
Mel's cheeks went a bit scarlet at the question. “Oh. Um, I used to have a bit of a hyperfixation on sex. Anal sex, specifically, during my first year of medical school. I would spend hours researching the anus and its stimulants. I always felt ashamed of it at the time. Now, though, the knowledge has become pretty useful.”
“Ah, med school,” Trinity reminisced. “We all had our own ways of coping. I got obsessed with sex, too. Though I'm not sure it was in the same way you were. I was more of a hands-on learner.”
A grin blossomed on Trinity's face, and along with it came a chuckle so bright it almost made Trinity forget the dirtiness of the moment. That is, until she was asked, “Can I penetrate you now?”
Trinity locked her jaw. “Under one condition: you leave the fun facts until afterwards. I only want to hear dirty talk from now on. I imagine you researched that, too, didn't you?” Dirty whore, she added in her mind, but she didn't say it out loud, as Mel didn't strike her as someone who would like degradation. “Be as dirty as you want. And enjoy the show.” That last line came out a bit too cringy, but hey, was there even such a thing?
“You got it,” said Mel, “tiger.”
Immediately one-upped with cringe, Trinity couldn't help but surge forward and capture Mel's lips with her own. The woman let out a quick gasp before kissing back. Her lips were thin and soft and slotted perfectly between Trinity's. Both of their tongues came out to dance.
Then, while they were still kissing, Trinity maneuvered her ass backwards until she felt the hard tip of the glass pressing against her hole. She thrusted her hips backwards and effectively penetrated herself by about an inch—all without breaking a sweat.
Mel let out a gasp against Trinity’s lips just as Trinity pulled them away. She looked the woman dead in the eye. “Fuck me,” she instructed.
As she'd already shown thus far tonight, Mel loved to follow instructions. “Yes, ma’am.” She gripped the dildo in one hand and Trinity’s ass cheek in the other, then started pushing it in.
The curved tip of the dick went about two inches into Trinity before pausing and wiggling around against her first set of muscles. The firm, hard glass was a stark contrast to Mel's soft, pliable fingers. It was thicker and cooler as well. As Trinity’s eyes stared with intent focus into the pillows beneath her, she felt her mind flash back to operating room 5: Glass Ass, the hemorrhaging, the embedded shards. She shook the memory away. She'd taken on this thing several times before; it was hard and strong, nearly impossible to break. Much like herself. She was much more skilled than Glass Ass. She set two goals for herself: not to think of the bottle, and not to moan until the end. The latter was a normal fun challenge for Trinity, but the former was a…unique conundrum. Still, they didn't call her Stick-to-It Santos for nothing. (No one actually called her that except her mom. But maybe after today, Mel could start it as a trend.)
Speaking of Mel…all this thinking was taking Trinity’s mind off the task at hand. Before she knew it, she felt the first round of nubs enter her, accompanied by a squeeze to her ass by Mel's fingers. She nearly lost her noise challenge instantly from that textured sensation inside of her.
After about another inch or so, Mel began twisting the dildo around in its socket, causing the nubs to rotate in circles against her walls. Trinity caught an involuntary breath, and her anus clenched around the glass just as involuntarily.
“Is this okay?” Mel asked observantly, pausing the motion.
Trinity nodded vigorously. She was inwardly cursing herself for not thinking of twisting it before, as the sensation was so delicious, and the newness had taken her more off guard than she'd ever be comfortable with. “Tachycardia,” she told Mel, phrasing the single mouth-watering word like a command.
It was a direct prompt to keep going, and Mel caught the meaning immediately, as Trinity had known she would—nerd. “Tachycardia. An abnormally fast heart rate, and the exact opposite of your safe word, bradycardia.” Mel said approvingly, resuming the movement. “Sexy. Your wish is my command.”
Perfect mix of scientific and dirty. Trinity could get used to this. After a few twists, she got used to the new feeling inside her as well. She was reminded of how much she loved glass. It was pointed and unmoving, and the bumps of this one further enhanced the hardness. She loved how it rubbed against her in so many ways and made her feel full. She took control again, rolling her hips backwards until about half of the dildo—six inches—was inside of her. To think—if she'd used the smaller glass one, she'd be done by now. Trinity was just getting started. But she needed one more orgasm before she could continue.
“Thrust inside of me to this length until I cum,” Trinity ordered. “Hard. Don't hold back. Don't treat me like I'm fucking fragile. I won't break.”
“I never thought you would.” Mel's voice was dripping with admiration. “You're so fucking strong. You make me feel weak.” Mel clenched Trinity’s ass so tightly it was as if it were the only thing anchoring her to reality. She pulled backwards so that the dildo nearly left Trinity’s hole, then rammed it back inwards perfectly to the six-inch mark. Trinity didn't even make a sound, although her eyes rolled back in pleasure.
“Again,” she grunted.
Mel, like the obedient little whore she was, obliged immediately. “I love when you boss me around. I'm so impressed by you, mommy.”
Impressed. That had been Trinity’s goal since the beginning. Mel's dirty talk went straight to her cunt, and her thrusts were perfect. They penetrated her to an almost teasing amount, then painstakingly retreated to ram again. Trinity couldn't help but feel impressed as well, but she'd never dare say that aloud. Soon, the only thing she was feeling was full pleasure and loss of control.
“Fuck, yes,” she growled, a needy hitch clinging to the end of the phrase, as she orgasmed on six inches of hard glass.
Trinity only gave herself ten seconds to recover. She wanted, needed to show Mel her willpower. “Keep going,” she ordered, barely even breathless. She already felt her walls loosening after the tightness of orgasm, more than ready to take even more inside of her.
Mel silently began pushing, vibrating the dildo like a vibrator as she did so. Trinity liked it, but—“What do you say?” she snapped.
“Y-yes, ma’am,” Mel breathed. That stutter made Trinity quiver just as much as the glass did. “My sex goddess,” Mel added as her hands moved to Trinity’s hips, caressing them as she pressed ever further inwards. “My fuck mistress.” Trinity smirked. She'd never heard that one before.
Trinity could viscerally feel her rectum being filled and stretched out. She had to bite her lip several times to prevent from whimpering or moaning. Instead, she let out a low drone: hmmmm. Soon, she began rolling her hips along with the movements of the glass. Mel's soft hands were all over her skin, and her hard dick was all over her inner walls. The nubs were even better this far along. Trinity’s slick cunt was pulsating, overtaken by both control and lack of it. “Don't fucking stop. Fuck me like you've never fucked before.”
“You're so hot.” Mel was adding motions so practiced that Trinity couldn't even catalog them in her brain. Trinity felt like she was on top of the world.
Eventually, she felt the dick hit the end of her rectum. She gasped despite herself—she hadn't realized that much was inside of her. Trinity’s rectum could stretch to about ten inches, which meant she only had about two inches left of the glass to take. And in order to do so, it would have to go through her second hole. The tip found friction against the small entrance, and Trinity gripped the sheets for dear life, eyes scrunching shut.
“Resting heart rate,” she breathed, hoping Mel would understand—she meant it as a yellow light.
Of course, Mel did understand. Her movements eased to a halt. Trinity stayed there for a few moments, getting used to the sensation of her rectum and anus being completely full, and a hard glass tip pressing against the tight entrance to her sigmoid colon. This was the hardest part, but she knew she could withstand it. “I'm ready,” she told Mel. “Go as deep as you can. Make my heart fucking race. You got that, slut?”
The nickname slipped out before she could help it. Luckily, Mel seemed to like it. “Yes, mommy,” she whispered. She slowly pushed the dildo into Trinity's hole. Trinity relaxed the muscle as much as possible, but it still felt tender and tight, burning, going in.
She knew what she had to do. Trinity shoved her ass backwards until it hit the base of the dildo, and thus, Mel's harness against her body. The final two rock-solid inches went straight through into her colon. And the best part—she didn't let out a sound.
Mel did, though. She gasped loudly. “Oh my God,” she said in surprise. Then: “Oh my God,” again, but in awe. Then, she blubbered, unable to form any more words. Speechless.
Trinity’s signature smirk pasted itself onto her face. Mission success.
She basked in the feeling of control for a few glorious seconds before willfully relinquishing it. “Thrust,” she ordered. Mel remained still for a split second too long. “Now!” Trinity shouted harshly.
Mel jumped and launched into movement. Using her hands on Trinity's hips as support, she rammed the twelve inches of glass repeatedly into the woman, up to the base every single time. Feeling Mel's hips hit her ass over and over was incredibly satisfying; Mel was learning exactly what Trinity wanted. And Trinity’s will was slowly fading away. The sensation of being full to the brim in every single part of her anus was almost too much to bear; her teeth clenched, and drool dripped from the gaps onto the sheets. Every pointed impact sent shivers rocketing throughout her entire body, especially through her rectal walls to the g-spot on the other side. Her heartbeat, felt both in her throat and in her pussy, was pounding along with each thrust. She was on fire. Trinity began pushing her ass backwards in an equally-perfect tandem, almost hypnotized by the rhythm and the hardness. Her eyes were open, but her vision was going dark. Her inner muscles spasmed.
“Trin. Oh, Trin,” Mel whimpered, as if she were the one being fucked. Trinity was a sucker for dirty nicknames, but the use of a personal one pushed her impossibly closer to the brink. The curved tip of the dick was ceaseless.
Upon a particularly strong thrust, Trinity felt her body succumb to the darkness, and she moaned uncontrollably. Intense pleasure filled her every nerve. It was an incredible orgasm for any woman—but Trinity knew she could squeeze out more.
Riding the last efforts of the high, she could feel Mel's thrusts slow down gently to a near halt. “Don’t stop,” Trinity whined. “Keep going. Hard.” She tried with all her might to put a commanding tone into her voice, but it came out pitifully needy and helpless. Trinity would never call herself a beggar, yet—“Please. Please, don't stop.”
Mel didn't. In fact, when she resumed her thrusts, they were stronger and faster than before. The focus became less on being precise and more on fucking, fucking, fucking deep. Trinity had no idea Mel could be so…relentless. The roughness further enhanced the raw post-orgasmic tender of Trinity’s insides. She felt like she was being torn up from the inside out. The pain was so pleasurable, sending sparks flying through her ass and the rest of her body. The pain in her anus, however, was nothing compared to her aching pussy. She was so fucking wet. She registered Mel's soft hands migrating to her waist and massaging her torso vehemently. “My clit,” she choked out, knowing deep within that Mel would honor the message.
Within seconds, she felt one hand digging its heel into her sopping clit, another gripping into her waist, and of course, the huge glass dick vigorously filling and re-filling her raw asshole. The combination of pressures was absolutely perfect. Even though she was rendered powerless, Trinity had never felt such godly, yet ungodly power. She was soaring.
Another, much more intense orgasm was on the horizon, and Trinity seized it with greedy hands. Her entire body began to quake from the pillar of sensation, and it felt as if her cunt was about to fall off. Everything tightened, sucking all the breath from her body. She heard a gasp from behind, from the perfect little slut that had brought her this—
“Mel!” Trinity screamed as she cummed uncontrollably.
Afterwards, she didn't remember her arms giving out, but before she knew it, she was down on her elbows, and steady hands on her waist were the only thing holding her lower half up. Gently, Mel eased Trinity’s limp body downwards until she was laying down on her stomach. Unable to be strong any longer after that powerful climax, Trinity instantly melted into the bed. There was a wet spot under her cunt. She registered Mel's fingers lightly brushing against her back under her scrub shirt. The whole world felt fuzzier and softer. The peak had been heavenly, but so was this.
After a minute or so, she craned her neck backwards towards Mel, who was still kneeling above her, looking down at Trinity’s face with those deep blue eyes, her gaze almost as penetrating as the glass had been. Trinity was in pain, but it was the most satisfying kind. She smiled at her coworker.
“Told ya so.”
Mel's only reply was capturing the woman's lips in a tender, reverent kiss.
After several beautiful moments of interlocking lips, Mel leaned in closer, causing the glass dildo to shift inside of Trinity. She caught her breath; somehow, she'd forgotten it was still there. Mel registered this reaction and began slowly pulling it out, inch by inch. To distract herself from the rawness of removal, Trinity started talking. Rambling. “To think, if I were Glass Ass, I'd be passed out on the floor right now with a million shards of broken glass in my rectum. But everything here came out smoothly, in one piece. Literally. I'm not on my way to the ER, I just left there.” She let out a sigh. “Thank God I'm me.”
“Thank God you're you,” Mel repeated in confirmation. “We should start calling you Glass Ass.” She didn't even seem to be joking.
God, Trinity was going to have the biggest ego on earth after this. As soon as the dildo was completely out of her anus, she launched upwards and spun around with renewed energy to bury her head in Mel's neck: peppering kisses all over the soft skin, nuzzling against her like a cat, basking in the woman's smell. “Your turn. What can I do for you?” she breathed, ready for anything Mel might throw at her.
Mel had a response ready immediately. “Would you let me tell you all those fun facts I was saving?” she asked.
Taken off guard, Trinity couldn't help but let out a snort. That wasn't quite what she had in mind. She never knew what to expect with Mel…but that was slowly becoming one of her favorite things about her. “Of course.” She leaned back on the bedsheets, trying to show off that she had a listening ear. Would nodding along be too dismissive? Should she add her own input? Conversing after sex, much less about the act, wasn't exactly her forte.
But then, Mel added something. “...And while I do so, could you finger me until I can't speak anymore?”
That was most definitely Trinity’s forte. She licked her lips approvingly. “Now we're talking.”
Excited by Mel's words and their prospect, Trinity pounced on her prey immediately. She leaped up to shove Mel backwards by the shoulders, causing the woman to squeak as her back and head hit the bed, Trinity falling along with her into a crouch. As soon as she was on top, her hands migrated downwards. Before she could get to her prize, though, she had to remove its hard shell. Within a few practiced moves, Trinity had detached the dildo, lubed up one hand, and unclipped and set aside the leather harness. The crotch of Mel's scrub pants had soaked through, leaving a damp circle. Trinity pressed the area with a palm, savoring the wetness, the shape of the cunt beneath, and the immediate needy hitch in Mel's breath.
“Trinity.” Mel was urgent and instructive. “After you remove my pants, insert two fingers simultaneously into my vagina, only up to the first knuckle, then curl and uncurl them. Go slow at first, then speed up. After a few minutes of that motion, repeat the process, but up to the second knuckle. When I say the word—which is digital—start tickling my clit with your finger. Just the slightest pressure. Mine is really sensitive, so I'll cum within a minute.” Mel paused. “I know I'm really particular,” she added apologetically.
“No, particular is great,” Trinity assured her quickly. “I like a girl who knows what she wants. I'm one, too.”
“Would you praise me?” Mel whispered tentatively.
“Anything you want,” Trinity soothed.
Mel adjusted her legs and glasses particularly. “Okay. I'm ready.”
Trinity was as eager to prove in giving as she was in receiving. She was an overachiever and she knew it. Her goal still remained blowing Mel's mind. She enthusiastically yanked down the woman's scrub pants so they pooled around her ankles. Mel hadn't been wearing underwear, just like Trinity, so her glistening slit was instantly revealed. It was positively mouth-watering. “You're beautiful,” Trinity breathed, and unlike sometimes, the praise came naturally to her.
In response, Mel began babbling nonsense. “Did you know that in 2020, a ceramic statue dating back to the Tumaco-La Tolita culture of approximately 600 B.C. was uncovered that depicts a man being penetrated anally? And that's not the only depiction of anal sex in ancient culture—”
Trinity had to stifle another laugh. She'd almost forgotten about Mel's caveat. The woman had given herself a little challenge, just like Trinity had when she was receiving. Maybe the two were more similar than she'd once thought.
Just like Mel had asked, Trinity's first movement was penetrating Mel's vagina with two slick fingertips at the same time. “...in Ancient Greek society, th—ah!” Mel whimpered. “In…in…mm…Ancient Greek—”
“So smart,” Trinity praised, slowly sticking her fingers in deeper until her first knuckles were submerged. Mel's pussy was warm and tight. “And so tight. Keep talking, kitten.”
“In Ancient Greek society…” Mel started over again.
Trinity was impressed at how Mel continued infodumping, even when she curled her fingers the first time. She felt the very edge of the woman's textured g-spot on the smooth wall. She split her focus between Mel's words and the sensation of fingering her needy pussy. Slow and steady at first, like a tortoise…then faster, like the rabbit… (Trinity really needed better metaphors for sex. At least this narration remained internal; externally, all she heard was fun facts, including how the origin of the word vagina came from Latin for sheath.)
Mel was sheathing Trinity’s pair of fingers so well that, after a few promised minutes, she began pushing deeper again. “The origin of the word penetrate…ah…ah!” Mel cried out as Trinity’s thicker second knuckles entered her.
“You're doing so fucking good for me,” Trinity breathed. “You have it all.” Indeed, she was seriously enjoying herself by now.
Trinity had previously been propping her body up above Mel by her arms, but she chose this moment to drop down onto the woman, slightly off-center. Their breasts slotted together as if they were made for each other, and their heads landed side-by-side. Trinity could feel the woman's hot, quick breath, as well as every friction their bodies made. She started curling her fingers inward. They made direct contact with the roughness of Mel's g-spot. Yes. In her excitement, Trinity accidentally pressed a bit too hard, and Mel let out a sharp yelp. She realized her mistake and started easing off. Slowly…slowly… Eventually, Mel's rambling came back, if a bit more strained and breathy than before.
“The g-spot,” Mel gasped out, “short for Gräfenberg spot, is a highly sensitive area on the front vaginal wall…” More…more… Trinity was intoxicated as she gradually sped up. She loved that these fingers could melt Mel in such a way. “And the clit…the clit is—shit!” Mel cried.
Trinity remembered to praise. “What a good girl. How do you take my digits so perfectly? I—”
“Digital!” Mel cut her off urgently.
Trinity's thumb was more than ready. It rose upwards and found Mel's clit immediately, then began brushing just slightly against it. The way Mel's hips rolled and she moaned, you would've thought Trinity had pushed very hard. The strong reactions were incredible, and escalated impossibly quickly with each tickle. So sensitive. Trinity couldn't help but stick her free hand down to her own groin as she meticulously fingered Mel's. She was determined to get the motions as perfect as possible. Curl, tickle, uncurl…The precision got harder and harder as Mel got squirmier and squirmier. She seemed physically unable to form words now. It was just what she had asked for—and it was just what Trinity had wanted, as well. “Damn, Mel,” she breathed, pressing ceaselessly, subconsciously into her own cunt. Her entire focus was on the woman beneath her, the one who made her feel oh-so good. She felt so impressed, with both her and herself.
Mel was a beautiful mess. Her hips bucked against Trinity above her, and a string of nonsensical whimpers escaped her parted lips. The only decipherable word was “Trin.” Trin couldn't see into Melissa's vision, but she hoped it contained stars.
Before she knew it, her hand was completely soaked, and so, indeed, was her own cunt.
“Fuck…” came a sigh of relief from beneath her. Trinity gently eased her hand out of the tender inside, which was pulsating quickly. She moved the hand to Mel's chest to feel her actual heartbeat, which was in perfect tandem with the lower one. 170 bpm, her mind automatically calculated. Fuck, maybe she was as much of a nerd as Mel.
In their position, with Trinity partially on top of Mel, she could feel Mel's wet, satisfied cunt (she had brought her that satisfaction) against her upper thigh, and her own cunt, equally as damp, created a mirror picture against Mel. They slotted together perfectly. “Did you cum again?” Mel asked breathily, clearly noticing their joint wetness as well.
“Yes.”
When Mel shook her head in disbelief, Trinity could feel her long, golden hair tickle her skin. “You just keep blowing me away.”
Normally, Trinity would've taken the compliment in stride, but something about Mel made it feel different. “You too,” she found herself saying. The two just laid there side by side, and Trinity bathed in the precious shared moments. This was where she always wanted to be.
“Did you know,” Mel broke the silence, “that wearing high heels causes the pelvic floor to contract, replicating the tilt of climax, so it makes it harder to achieve a full pleasurable orgasm as the body becomes accustomed to the angle?” She paused. "We should be glad we were both barefoot during that."
This time, Trinity couldn't hold it back. She burst into laughter.

It was awkward in bed later that night.
They'd cleaned up. They'd showered. They'd had a second round of ramen. Now, they were laying apart in Trinity's soft bed, heads on separate pillows, completely untouching. It was dark.
The silence was broken when they both started speaking at the same time. They squabbled for a bit over who would go first, then Trinity just went for it. “I'm not good at saying this, but…thank you. For letting me show you this, and for letting me touch you, too. I know I can be a bit of a show-off.”
“No, Trinity, thank you,” responded Mel from the other side of the bed. “Usually, I’m either not given the opportunity to spend the night together after sex, or I’m too overstimulated to,” she confessed. “You changed that. And you listened."
“Oh. I usually sleep alone afterwards, too.” Trinity’s words came out hollow. She felt uncomfortably vulnerable and awkward, but something about relating to Mel put her at ease. Any nice words she wanted to say caught in her throat. She reached her hand across the bedsheet to grab Mel's, then gave it a soft squeeze, hoping to convey everything she felt.
Instead of simply squeezing back, Mel pulled her into a cuddle. She wrapped her arms around Trinity's shoulders, effectively tucking her into her chest. Trinity was usually the big spoon, but tonight had already proven itself to be far from usual. Despite her inhibitions, she relaxed in Mel's embrace. She wondered how this would change things between them. She realized that, at least right now, she didn't care. She allowed her mind to slip deeper into the darkness. She'd done it.
“Goodnight,” Mel mumbled.
“Goodnight, Mel.”
“Goodnight,” Mel repeated, “Ms. Glass Ass.”
Even as she drifted off to sleep, Trinity’s smirk didn't fail to permeate her face. It had a good ring to it. She'd always known she was worthy of the title. And she sensed that Mel had, too.
