hii ms knife :)) feel free to ignore this if you’ve alr written something similar
thinking about mari who’s attempting to use the strap on reader for the first time. like she was being so cocky about it and was very convinced that she could do a better job than her gf does for her.
she holds onto all of that confidence until she’s actually there and it’s so obvious that she still needs her gfs help and she’s lowk so pathetic about it
sorry im not sure if this makes any sense!!
» mari ibarra x fem!reader.
— warnings: mari’s first time strapping, so inexperienced!mar & nsfw content. mdni. strap-on usage (reader!receiving). the ending is a little rushed, but whatever.
mari is sitting up on her knees, her crisp sheets crinkling when she shifts her weight to stare look down at the pink toy currently jutting out from between her thighs, attached to the harness that sits snug around her hips. the dildo sways back & forth with her, making mari curse under her breath as she wraps her fingers around the silicone base to steady it. lying naked on your back, all spread out already, you can’t help but giggle at the clumsy sight of her, which earns you a stern look from mari. “i don’t have to do this, you know?” she mutters, giving your eagerly spread legs and your bare body an annoyed once-over.
“right,” you nod and press your lips together to keep the grin at bay. “right, of course, sorry.”
“shut up.” the mattress dips as mari shuffles forward on her knees, looking down at you only once she’s kneeling right between your legs, and the underside of the dildo rests flat against your abdomen. her eyes flick between your face & your cunt on full display the rest of your body, as if she cannot quite believe it, either, that after all this time of getting fucked with this toy, it is now her turn to use it on you. biting your bottom lip in anticipation, you offer a shy smile up at her the next time mari meets your gaze. “s-shut up.” she says again, already a whole lot less steady. “do you want me to fuck you or not?”
“yes, mar.” the sincerity with which you answer her momentarily seems to catch mari off guard, and she blinks at you blankly for a second before snapping herself out of it. still looking at you, she starts feeling her way up your thigh, giving it a squeeze before then roughly pushing it up to your chest, clumsily mimicking how you usually touch her.
although she is clearly new to this, the change in position has the silicone tip slipping, accidentally bumping into your clit, and making you gasp in surprise. “fuck.” mari mutters, pulling in the opposite direction, this time, so that the dildo dips a little too low and instinctively makes you clench.
“i know that, smart ass!” she wraps her fingers around the base once more to line it up at the right angle, dragging it through your folds a little more roughly that she probably intends before finding your entrance. “here, just let me fucking-“ hoisting you up, the next poke of the tip doesn’t miss its target, breaching past the initial stretch so that the head of her dick notches inside.
“oh, shit!” your breath hitches, fingers instantly curling in the sheets as the walls of your cunt clamp around the first few inches of the dildo. mari’s own hips jerk, too, only that she seems to overestimate the room she’s working with, here, because the backwards motion causes the toy to slip out all over again. grunting in frustration of evidently not being as smooth with it as you usually are when you’re wearing the harness, mari shuffles closer to retake her aim. with the head still against your entrance, she pushes forward more steadily, sinking inside smoothly, if only because of how wet you are by now.
it’s far from the biggest toy you keep stored away in the bedside table’s drawers, and you’re thankful mari let you talk her into not using one of the larger dildos, because you doubt she would’ve managed and fear it would’ve bruised her ego too much for her to ever so much as try again had she fucked up. this one, on the other hand, fits comfortably and doesn’t slip back out as mari adjusts above you, leaning over your body for easier access.
only about half of its length is actually inside, with her not properly fucking you yet, but once mari is draped over you, and you put your arms around her, you cannot help but moan into her ear at the first hint of a stretch burning in your core. it is enough encouragement for her to give a first reluctant thrust, the dildo thankfully staying inside and not awkwardly slipping out one side or the other. “fuck-“ immediately, your body arches up from the mattress and into her, the sensation of that initial stretch subsiding and turning into hot pleasure spreading in your abdomen instead.
braced on her hands on either side of your head, mari momentarily looks pleased, a shit eating grin on her lips as she repeats the motion, though her face falls just as quickly when you groan and try to rock your hips to meet her thrusts. “harder, mar. fuck me.” having her inside you does feel good, no doubt about that: it’s a stretch already much bigger than just her fingers and probably the most mari has ever fit inside you, but with all her talk about “how good she’d make you feel,” and how “she’d make up for all the times you’d put her through the mattress,” you’d had higher expectations for how she was gonna take you with it.
“what do you think i’m doing?” mari hisses, at the same time still trying to pump her hips.
“how would i know, it’s- oh!” mari drops from her hands to her forearms, using the change for leverage to thrust harder. it’s still kinda obvious that she isn’t familiar with moving her body like that, the movement clumsy, but the silicone shaft strokes up against your g-spot all the same, if only on every second thrust, and so your body tenses beneath her. your abdomens are pressed together with how short the thrusts are, but there’s still enough wiggle room for you to sneak a hand between them, run it down your front, then between your thighs. glancing down, mari frowns at the sight of that. “hey! i wanted to-”
needing her to fuck you already, you shake your head. “you,” you pant, “focus on that, i’ll just-“ the contact of your fingertips against your swollen clit has you inhaling sharply, your legs falling open wider.
watching you rub your own clit, mari’s pout vanishes, determination taking over her face once more. you’re glad for it, doubting she would’ve been able to multitask, so that you can focus on your clit while mari figures out how to fuck you with a cock. with the extra stimulation, combined with the sensation of your fingertips working over your clit, pleasure soon spreads, your pussy squeezing down around the silicone as soon as she picks up her pace again.
to keep yourself open for her, you lift one of your legs up and over the small of mari’s back as she experiments with the pace & pressure until finally, fucking finally, finding a combination that works. “is that good for you?” she whispers breathlessly, her lips brushing over the side of your face.
“y-yeah,” you’re surprised to find that it’s true, gripping mari’s shoulder tighter as she keeps rocking her hips, now fucking the strap in as deep as it’ll go. its shaft strokes along your fluttering walls, so much so that the intensity of the feeling actually catches you off guard, too. “yeah, that- mhm, feels so good, mar-”
humming happily, mari keeps jerking her hips faster and, with that, also more clumsily, the deeper the nails of your free hand dig into her shoulder blades, two fingers still rubbing quick circles over your clit. it’s a mix of sensations that, once she figures it out, pushes you towards the edge faster than you’d expected. granted, her fucking is still far from steady, but there’s something to the desperation with which she moves, the eagerness to make you feel good, plus the feeling of your fingertips against your swollen clit, that makes it impossible not to chase that sweet release.
when it builds and builds, and you gasp: “oh god, mari, i think i’m gonna-” it’s still a shock for both of you, but by the time you realize it’s true, that you’re going to come on her dick, you already are. with the support of your own hand and a lewd cry, you work yourself over the edge and go rigid under mari, who, with a little grunt herself, bottoms out to the hilt before she leans back and watches the pleasure wash over you, leaving the toy where it is for your cunt to clamp down around as you ride your climax out.
