A strange little monster wandered the deep dark depths of long forgotten dungeon. Though when talking about monsters, small was a relative term. He was shorter than his mind flayer friend, and MUCH small than his carrion crawler friend, but they generally hung out much deeper in the dungeon. As a rust monster, the twin-tailed bug was actually about average size as it skittered about, exploring the upper levels of its home, having seen natural sunlight for the first time a while back. It was curious about what things were like up there, and decided to set off, aimlessly going down the many winding halls until it came across a creature it had never seen before. It looked like almost like a human, but it wasn't nearly as big as the ones it generally saw, and wasn't covered in food either, or moving around very much. Maybe they had already met his mind flayer friend? If so, the carrion crawler was likely already on its way, but for the time being the rust monster decided to check it out for itself, scuttling up to the being and letting its wriggly antennae explore her odd coverings

The Adventurer had been quietly sitting and eating some dry rations when the rust monster had approached. It had been a long day traveling to this place, just getting here before it got dark. Her feet ached and it was better to camp out up here where it seemed quiet rather than going deeper. The sorceress needed to be on her guard when she began properly exploring this ancient, forgotten, dungeon. At fist, she didn't notice the odd creature, too busy getting ready to sleep for the night. A gasp escaped as she caught sight of it out of the corner of her eye, her heart beating faster with uncertainty at what it was going to do. Instead of attacking, though, the odd monster just went up to her and began touching her with its antennae. "Oh, hello there!" She offered jokingly as those tendrils ran over her light leather armor. It was little more than sturdy coverings but that was still better than nothing. The Adventurer reached out and stroked its head to show she wasn't a threat, "What're you up to, hmm?"

The critter trilled at the attention, jittering excitedly. Looks like it found a new friend! It would have to tell the illithid and carrion crawler about this later. Though it was a bit distracted when its antennae found snacks in the form of the metal clasps used on some of the straps for The Adventurer's leather armor. They immediately rusted and fell down into her lap, the armor itself coming loose. The rust monster turned its attention to the metal bits and started chowing down, unintentionally rubbing against The Adventurer's crotch as it did so, and to top everything off it drooled slightly as it ate, lightly soaking the area. And with it so close, it was hard for the monster not sense the metal buckle to her belt, so of course it turned around to start trying to weasel its way under her light leather armor to get to that

The Adventurer just stared for a brief moment as the clasps rusted and fell off. It took a moment for her to process but she had heard something about this before. This creature was a rust monster! They weren't dangerous, exactly, but anyone wearing a lot of metal was basically a walking banquet for them. She was glad that she couldn't wear anything too heavy, otherwise it would interfere with her magic. The Adventurer giggled softly as the critter ate the clasps, only to let out a soft moan of pleasure and surprise as it started rubbing up against her. Was this rust monster aroused? It was hard to tell. It started going for belt buckle, which could have been taken several ways. The Adventurer bit her lower lip, glancing around, deciding to check if anyone was looking while slipping the claspless armor off and giving the rust monster easier access to her belt. She also drew her knife from its hilt, setting it down so that she could feed it to her new friend and blushing as she leaned over to try and sex the critter.

The rust monster's head went back and forth as it tried to decide if it should be focusing more on its new friend or the offering its friend laid out for it, eventually opting to go for the dagger, partly stepping on one of her legs to reach it better, which also just so happened to allow her to reach under the monster better as well. This particular critter was a bit smoother than most of its species, the chitin being more or less free of lumps, the underside even more so. its body was naturally arched, its back going up and stomach distancing itself from the ground accordingly before going back down for its long, swishy tail which ended in two stiff prongs. Right where the underside of the tail began, however, there was a lump that seemed very out of place, occurring at an intersection of plates. It seemed it wasn't actually aroused quite yet, male or female, but a bit of stimulation should open things up to reveal whatever was underneath

The Adventurer could hardly believe what she was doing, but she found herself overcome with curiosity and desire towards this odd creature. Adventuring life led to a lot of strange activities, it seemed. With one hand, the sorceress continued to pet the rust monster, stroking the chitin along its back appreciatively while her other hand dipped below. Fingertips brushed along that lump, stroking it gently, hoping to coax out what it might be. "You're a cutie, aren't you? All alone? Me too. Let's be friends, okay? I'm The Adventurer." She looked the critter over, curiously, "We should give you a name too, though. Don't you think? How about Clasper. Since you ate my clasps and all."

The rust monster, now called Clasper, liked its new name. Generally having a name was something only the illithid did, so it made the creature feel special, though not as much as when she started rubbing him. A tiny pink nub poked into The Adventurer's hands as she caressed him, nudging the chitin apart just enough to squeeze by. It extended itself slowly, inch by inch, a pinkish-orange in color and marked by seemingly random ridges and angles, likely to aid in mating with another of its species, as their relatively stiff bodyshape would make most traditional poses awkward with eachother, but with a human who could just fit underneath? It would likely take a bit of talent to fit everything, but the act itself would be... unique, but deceptively simple. Clasper looked back from the half-eaten dagger, his head tilted curiously at her in wonder at what she was doing, though his wagging tail betrayed excitement

The Adventurer was more than a little surprised by what she coaxed out of Clasper, the rust monster, but also very intrigued. She certainly hadn't expected him to be so... generously proportioned down there. "Oh my gods," The sorceress whispered as she stared at it for several moments before her attention shifted to the critter now looking at her. "Excited? Me too! We can have a lot of fun together, if you like." Her hand that had been petting his back went down, quickly loosening her belt and sliding it out of the loops in her breeches while she kicked her boots off. Wriggling on the floor, the sorceress worked to get out of her pants while continuing to pet and rub Clasper's shaft. "Does that feel good for you? Do you want more?" She blushed, leaning closer, "Do you want me to suck on it?"

So many new experiences today! Clasper got to explore new places, where he found a new friend, who seemed to want to be his first mate! Though... he wasn't sure how to mate with a human. Generally he'd just move on once he ate the armor off whatever adventurer delved too deep and let his friends take care of the rest, so human anatomy was still largely a mystery to him. He started off with what he could reach without too much difficulty, nibbling lightly on her belly-button, since her head was a bit too far back for him to reach. While waiting for her sex to reveal itself from her navel, his antennae took the time to grope around for other likely spots in case this happened to be incorrect, one feeler snaking its way under her tunic and finding a nipple, meanwhile the other when the opposite direction, quickly finding a warm, wet cavity that may or may not have been a second mouth. He'd have to be careful with that one

The Adventurer giggled as Clasper gave her belly button a light nibble, kicking her legs as she finally managed to get them free from her breeches. A delightful little shiver ran through her as those antennae brushed over her body, making her stroke him a little faster. "Oh my... yes, there's the spot." She unbuttoned her tunic, shrugging her way out of it so that she could be completely naked. It only seemed fair since Clasper was similarly lacking in clothing. Reaching down, she touched herself, running her fingers along the moist lips of her sex, hoping to prepare herself for when Clasper got into position. "Down there. Right there. Come on, Clasper. Move around for me." The Adventurer released a heavy breath, her heart pounding inside her chest, "Gods, I can barely wait!" The sorceress rolled over, getting onto her hands and knees to present herself before lowering further so that there was room for the rust monster to mount her.

Clasper made his little squeal again when The Adventurer got on all fours. Positioned like that it was much easier to think of her like another rust monster and let instinct figure out more or less what to do. One leg and then another climbed up on top of the girl, a surprising amount of weight coming with it. His long member prodded against her. Two holes. He wasn't expecting two holes. Testing them both with some quick thrusts, the bottom one seemed a bit easier but what if it was a second mouth after all? He decided he'd have to try both, starting with the easy one seemed like it might make the drier one easier later as the liquid seemed quite slippery. His tip flared slightly as it entered The Adventurer's waiting vagina, slowly at first as it made sure it was properly lined up, but from that point on it stuttered, jamming two inches in, then pausing for the briefest instant before jumping another inch, then back then another 3 inches in, a ring around his cock suddenly invading halfway through the thrust

The Adventurer couldn't help but grin at Clasper's squeals of excitement. He seemed very happy about the prospect of making her his mate. The sorceress was momentarily surprised by how much he weighed as he began climbing atop her, but she could handle it. A blush reached her cheeks as his rust monster manhood poked at her holes and she nearly jumped. While she wasn't opposed to letting Clasper bugger her at some point, there would have to be some prep work done beforehand! The Adventurer began to reach back to help guide him, but Clasper, smart little cookie that he was, figured it out on his own. Her hand dropped, sliding across the floor before coming back beneath her to support her. Low moans spilled from her lips as he began pushing in, going slow as he started to fill her. "Oh... oh yes!" Little breathy sighs and soft whispers of approval followed as he began mating her, The Adventurer reaching back occasionally to stroke him affectionately. "That's it, Clasper. Oh, like that! Easy... easy. Take it slow at first, okay?"

After what seemed like ages, Clasper managed to hilt himself in her, shouting out a celebratory whirr. That said, he wasn't don't yet. He pulled back out partway, only to swoop in low and push it steadily back in with enough force to lift up The Adventurer's rear! He quite liked the sensation, if the clicking of his mandibles was anything to go off of, and the fact that he did it a few more times. Eventually satisfied that he was as deep as he was going to get, he planted his hind legs and his cock suddenly began to vibrate, stronger at the base but still easily able to be felt way at the tip, the rest of him was surprisingly stable, stuffed in as deep as he could go and doing his best to pin his mate in place so that whatever he was doing could have its full intended effect

The Adventurer made some rather pleased sounds of her own as the rust monster hilted himself inside of her, gasping with shock, delight, and certainly a little bit of pain each time he hilted again. It was going even better than she could have imagined and then it got even better from there! She felt Clasper plant his legs, as though preparing, and then it happened. The Adventurer's back arched and she cried out, surprised but oh so very happy to be. It was unlike anything else she had felt before but it was sublime! She was dripping with desire as Clasper vibrated in her, slowly rolling her hips, trying to thrust herself on him since he seemed so focused on doing what he was doing. "Sweet gods above!" The Adventurer buried her face against her arms, desperately writhing against the rust monster and quivering with newly discovered pleasures.

Just when any notion of more traditional sexual actions were forgotten, Clasper started slowly dragging himself in and out of her, still vibrating, but otherwise slowly and gently fucking her in time with her own thrusts, a light smacking just audible over his chittering and the ambient humming of his vibrations whenever the two were brought entirely together, though he never pulled himself too far apart with no more than half of him ever leaving her sopping entrance. He lowered his head to be next to hers and let his antennae go back to exploring, still curious about the bits he had found on her chest. He quickly found the one from before and shortly thereafter found a matching one. What could these possibly be? His antennae flicked and swirled around them in wonderment. There was nothing like this on other rust monsters, nor did he remember seeing things like this on the rare occasion than an illithid had a bare chest

From the sounds that The Adventurer made as those long, feathery, antennae brushed and ran along the tips of her breasts, their purpose seemed to be for increasing her pleasure. The sorceress said very little, only moaning and sighing as Clasper slowly and steadily fucked her with his wonderfully vibrating member. She rubbed her face alongside his, eager to show him in as many ways as she could think to that she was thoroughly enjoying the mating. Her toes wiggled and curled, each thrust sending a wave of sensation crashing down on her, chipping away at her resolve and pushing her closer and closer to her peak. The Adventurer had decided to explore this old dungeon in the hopes of finding treasure like any proper adventurer, but she was fairly certain she had already found the greatest treasure this place had to offer. Through the blissful haze, she decided to take Clasper with her, assuming he was interested in leaving after their passionate night together.
