      "(Y/N)!" A ridiculously loud yell came through the house as soon as you managed to get the door closed behind you, and you heaved a slight sigh. You could already hear your girlfriend's footsteps come bounding from somewhere else in the house – no doubt from the small engineering lab she'd installed herself.

     Mei came rushing around the corner as you kicked your shoes off inside the door of your shared home. You gazed to her as she appeared, a wide, semi-permanent grin on her face. Opening her mouth to say something, she paused, expression becoming slightly more serious.

      You guessed it was pretty obvious you'd had a hard day from the way she picked up on your tense demeanour so easily. Being a Pro-Hero was never easy, but today had been particularly hard. A particularly bad encounter with a villain had left you with a mountain of worries and stressed, so much so that you returned home for the day without even changing out of your skin-tight hero costume, nor stopping off at your agency on the way back.

      "Hey, Mei." You gave your girlfriend an exhausted smile. Even if the day had been bad, you weren't willing to take your frustrations out on your girlfriend. "How has your day been today...?"

     "I've been adjusting some new babies." She declared, but her expression didn't lift back into her usual enthusiastic grin, instead blinking her wide eyes at you in concern. "I guess you haven't had a day filled with such delights as my babies? You look tense."

     "Yeah." You nodded apologetically, dumping your belongings on the small table in the hall, stretching in the hopes that it would relieve some of the pent up tension in your body, it felt like you were on the verge of cramping up just about everywhere. "Kinda stressful... Sorry."

     "Don't say sorry!" A sudden grin came Mei's face, clapping her hands together in excitement, making you flinch. She darted towards you, pressing herself against you and wrapping you up tight in her arms for a hug. "Wow! (Hero Name) really is tense! I can feel how clenched her muscles are!"

      "I guess (Hero Name) is pretty tensed up right now." You gave a soft laugh at the use of your hero name. Mei always had been fond of it, half the time preferring it to using your actual name. You wrapped your arms around your pink-haired girlfriend in return. "Nothing a nice warm bath won't solve."

      "No!" She leaned out of the hug, gripping both of your wrists in her hands, that dazzling grin coming back to her face once again. "I have a new baby I've been saving for just a time like this!"

     "Ah...-" You slightly laughed, shaking your head. "Maybe now isn't a good time to test it with me, Mei."

     "Now is the perfect time!" She countered, and despite your protests, was already dragging you with her down the hall, both wrists captured by her hands. "(Hero Name) is going to love it, I promise!"

      You didn't respond. You weren't exactly keen on having another of your girlfriend's inventions tested out on you, but you decided to comply and trust her when she said that you'd enjoy it.

      "Shouldn't I at least get changed first?" You questioned as Mei dragged you into the old office room that had been effectively converted into 'Mei's Babies HQ'. She momentarily paused in the doorway.

     "You have spare Hero Suits, right?" She questioned seriously, and you quirked an eyebrow.

     "Mei, we share a wardrobe, you know I do. Why, what are you planning-?"

     "Excellent!" Mei cut off your questioning to drag you into her cave of wonders, kicking the door closed behind you both. "In fact, this is a great time to show (Hero Name) all of the new babies she hasn't seen yet!"

     Your girlfriend released your wrists, turning to the large metal work bench that sat in the middle of the room, gathering armfuls of trinkets off the table, dumping them elsewhere, to clear space.

     "What've you got planned?" You tried to question again, picking up a couple of the many inventions in your hands, gazing at them curiously. The table now cleared, Mei turned back towards you.

     "Ah! Exactly what I was looking for!" She exclaimed upon noticing the strange inventions you held in your hands. She'd managed to avoid the question yet again, snatching them from your grip and holding them up to the light in admiration. A pair of metal loops with large magnets connected to the bottom of them. "Here!"

     The look on Mei's face could mean nothing but trouble, grinning ear to ear with a chesire-cat air.

     "What are they?" You tried a different question, watching inquisitively as she snapped the loops of metal open, grabbing your wrists and snapping them closed around each one respectively with a metal click. "Huh?"

     "Magentic hand cuffs, perfect for apprehending villains!" You blinked a few times at her words, wondering how this was supposed to work when the two cuffs weren't even linked, before she pressed a small button on each one you hadn't even seen. Nothing happened, but she dragged you over to the now clear metal table.

      "Mei?" You questioned, brow creasing with a frown, but she quickly hoisted you up onto the table, shoving you onto your back. She pushed your hands down beside your head, and with e metallic clunk, you finally understood how the cuffs worked. "Hey, wait-"

     You attempt to protest, but it seemed Mei had her heart set on this. The magnets attached to the cuffs had stuck to the metal table like glue. It was almost scary how tightly they held your wrists to the table as you attempted to tug them free, only to find not even the slightest bit of slack.

     "My babies are working perfectly!" She cheered, practically sparkling with pride. She stared at you, sprawled out on the metal table for a moment, before disappearing out of your line of sight. You could hear her shuffling to find something at the head of the table.

    It went quiet as you heard her tinkering somewhere out of your sight, and you face flushed as you took in the situation. You could feel your chest thumping in your chest rapidly. Despite how uncomfortable the position was, you couldn't ignore the small burning of excitement as you wondered just what your girlfriend could be up to.

     "(Hero Name) is going to love this!" She declared, and you heard wheels rattling across the floor, craning your head to see what she could be bringing over. "It'll relieve her tension just like that!"

     You almost choked as her 'invention' came into sight, brought to the side of the table on a wheeled trolley, since no doubt it was heavy.

     "You- You made a fucking machine?" You barely choked out your words, gawking in shock at the creation.

      "I did!" Your girlfriend nodded shamelessly, picking up a pair of safety scissors, pushing your thighs wide open to which you gulped. You held perfectly still as she cut a small slit in the material of your hero suit, and tossed the scissors into a pile of inventions.

      You groaned slightly in arousal as she tore the material open wider at the crotch, shoving your underwear off to the side, so that she could have your core exposed for her. She grinned in pride, noticing how quickly you were growing wet.

      "Relax and let Mei's babies take care of you!" Staring at you with golden, cat-like eyes, Mei rubbed over your core quickly, smearing the growing amount of slick.

      After a moment, she shifted the lewd machine between your thighs, the almost laughably bright neon pink dildo inching closer towards your needy core.

      "W-Wait- Shouldn't you prep me?" You stammered out, as she fiddled with the machine, adjusting the positioning of the dildo intently so that it could be at just the right angle. You gulped, the tip brushing against your damp folds.

     "I think (Hero Name) just wants to feel my fingers." She grinned, but complied, kneeling up on the table beside you. Her fingers traced over your slit before dipping into your hole, pushing in down to the knuckle.

      You sighed out in pleasure as he digits dragged along your inner walls, the frictions making you mewl out faint moans. Though, Mei didn't continue with this for much longer, sliding her fingers back out almost as quick as she'd jammed them in.

     "My baby will make you feel just as good!" She grinned in pride, making sure the dildo was once again nuzzled up against your folds, before reaching over to the control panel. "Just relax and let it take away all of your tension and stress!"

      She flicked as small switch on the machine, and it lurched forwards, the silicone cock pushing between your folds, easily slicked by your wetness. You sighed out shakily in pleasure as it slowly began to plunge in and out, brushing up against your walls.

     "It feels good?" Mei inquired with an enthusiastic grin, hands reaching out to slide along your body, still covered by your tight-fitting hero costume. You nodded with another soft mewl as he hands came up to greedily squeeze at your covered breasts. "Good! My baby is working perfectly then!"

       "More." You pleaded softly, attempting to tug at the cuffs keeping your hands pinned to the table beside your head.

      Your girlfriend grinned in satisfaction, reaching over with one hand to turn a dial on the side. The machine began to plunge the silicone cock in and out with more vigour and you whimpered out in satisfaction.

      It was both girthy and long, you had no doubt Mei had picked the biggest one she could get her hands on. The feel of it dragging along your inner walls making your breath come short, hips beginning to roll down against it as the machine fucked into you.

     Mei was quiet, for once, admiring the way her creation thrust you into pleasure, the way the cuffs held your vulnerable body so securely for her own awaiting hands to explore. She seemed hyper-fixated on your covered breasts, eyes glued to the way they bounced as the machine fucked into you. Her hands slid along the material of your hero costume again to grab at your chest, pinching at your nipples through the material, to which you whined out softly.

      Reaching out to turn the dial up more, Mei giggled as she watched your face contort as the machine picked up yet more speed, pace steady and unrelenting in drilling into you. It was quick enough that you could barely catch your breath, unable to hold back the high-pitched cries Mei was so pleased to hear from you.

     The heat was consuming, no doubt about it the machine was good, fucking you so steadily, pushing in so deeply that you felt the burning pleasure more fiercely than you had in a while, and your hips desperately squirmed in an attempt to escape the intense sensation.

     "No escaping!" Mei giggled mischievously, and went from kneeling beside you to swinging one leg over your body, settling herself over your hips.

     "Intense." You gasped out with a flushed face, and she merely grinned wider. Sat over you like this, it effectively held your hips still, your hips unable to escape the machine ploughing into you deeply.

      "Good!" She giggled loudly, reaching behind her to crank the dial up to the highest setting. There was a moment of numbness before the pleasure came rushing in like a tidal wave as the machine went into overdrive. The silicone cock was relentless in stretching and pounding into your core, reaching impossibly deep, not a second for respite, and you cried out, body squirming desperately underneath Mei.

     She watched you like a hawk, grinning down at you as your pleasure built up and built up, helpless to resist against the machine. The view was too hot to just sit and watch, so Mei began to rock her hips with a glimmer of excitement.

     Soft moans of her own began to escape as she stared down at your face, flushed and pinched in an expression of pleasure as she grinded herself down against you. Just watching you like this, getting fucked so well by something of her own creation was enough to get her all hot and bothered, and she had no shame about getting off to the view of you- hell, using your body to get herself off with.

     Your climax was fast approaching, there was no way you'd be able to hold it off- not that you wanted to. The worries and stresses of the day completely forgotten, completely unable to focus on anything other than the burning pleasure that numbed your mind completely.

     Straining your wrists against the cuffs, your orgasm arrived once Mei reached down with a single hand, wrapping her fingers lightly around your throat and giving the slightest squeeze. It hit you like a truck, and your back arched dramatically as you came, soaking the silicone cock with your juices, a strangled cry hanging on your lips.

     It was only made more intense by the fact that Mei left the machine running, having it fuck you viciously through your orgasm. As you came back down from your high, your legs were trembling violently, and Mei was practically drooping, humping herself against you.

     "Fuck..." You groaned softly from a combination of your girlfriend getting herself off on you, and the machine still abusing your hole.

     "Yes! Yes!" Mei cried out loudly after almost a full minute as she hit her own climax, hips rocking dramatically against yours as she soiled the sweatpants she was wearing.

     Panting heavily, she came back to her senses, gazing down at you through hazy eyes.

     "Mei-" You mumbled softly, hips attempting to squirm away from the machine that was still going at your core. "Turn it off."

     "Oh?" Mei tilted her head with a grin coming back to her face, turning to peer over her shoulder as the pink silicone continued to drive into your oversensitive hole.

     "No, I think my baby needs a little more testing, let's see how long (Hero Name) can take it!"
