You and your party had been in this dungeon for a few days now, exploring, looting and fighting your way at a safe pace. Things had been going well so far and you had just set up a camp to rest a while when Brunhilde left to 'scout' the area. Moments later she called everyone to attention and pulled you out of your tent. "Come with! Bring your tools! I think I found a vault door!"
The promise of loot made everyone eager and forced you to put off sleeping after a full day of performing your rogue-y labor just a bit longer. "Better be worth it," you mumbled, motioning for Brunhilde to lead the way. Instead, she grabbed hold of your wrist and began running.
"There it is! See? It, or I guess 'she' just hangs there!" Brunhilde exclaimed, pulling you along by your arm. "Damnit, Brunni, let go of me already! I can follow you just fine if you- what the fuck is this?" you yelled, your rant cut short by the sight of the odd 'lock' Brunhilde wanted to show you.
The door the lock was attached to was massive, ornate and screaming that there were expensive things behind it. The lock itself, as pointed out by Brunhilde, wasn't any less impressive, either. It was an ornate cast-gold figure of a woman, about half the size of a real adult human. Her arms functioned as an interlocking mechanism to keep the door shut from the looks of it. Before you could get a good look the Lock-Lady's head turned to face you, a look of defiance replacing her previous apathy.
"Be-begone, foul violator of locks far and wide. My less magical sisters cried your name many a time as you forced your tools into them!" the Lock-Lady yelled, startling both you and Brunhilde.
Meredith, the spellslinger of your party exclaimed a cry of delight at the sight of the Lock-Lady, pushing you aside to inspect her thoroughly. "My, what intricate craft, such perfect details; and autonomous locomotion to boot! Everyone!" Meredith called out, "This lock can't just be broken open, I don't even have to cast any detection spell to sense this. Roger, you gotta pick this lock."
Brunhilde and Meredith stepped aside, watching as you inspected the Lock-Lady, her legs locked tight, glaring at you as she hung on the vault's door. "I, uh, I don't really see anything I could call a 'lock', Mery." you admitted after a few moments of just ogling the bare beauty of the Lock-Lady nude form.
Brunhilde grunted, agreeing with you. "Huh. I guess that's right. Hey lady? How do we open you?" she asked bluntly, making you turn to face her in disbelief.
When Brunhilde simply shrugged, confused by your reaction the lock-lade laughed. "Me, being unlocked by the likes of you? Hah. Only my master can unlock me. It's only at his touch that I..." the lock began, trailing off as she realized Meredith listening to her with a certain glint in her eyes.
"Oh no, do go on. Only your master's 'touch' can unlock you, yes? From your looks he must be quite the pervert, I imagine." Meredith cooed. She stepped closer and tried placing a hand on the Lock-Lady, only to be stopped by an invisible force. At that Meredith quickly took a step back, spitting on the ground angrily. "What, am I not your type?" she yelled. Brunhilde laid a hand on Meredith's shoulder, shaking her head as she said "Nah, 's not that, Mery. I can't touch that metal lady either. Wanted to try yanking her off before I fetched you. Was as successful as you were."
While you were busy taking in all of this information the two members of your party faced you, watching expectantly. When you didn't immediately catch their drift Meredith tilted her head, nudging you towards the lock.
"Look, this is just going to reject me too," you muttered, moving to grope the left breast of the Lock-Lady, fully expecting to be pushed back by the same invisible force that blocked Meredith and Brunhilde from touching her. You were facing your party as you did this so you were as surprised as the Lock-Lady when your hands wrapped around the Lock-Lady's oddly supple metal breast.
The Lock-Lady moaned and writhed in place briefly, her arms remaining locked in place. A burst of energy washed over you, not affecting you in any way as you turned to watch Brunhilde and Meredith get knocked a few feet back by the blast. "Uh...." you began, unsure of what to feel as you groped the Lock-Lady's bosom once more. This time she did not moan, she only glared, though you felt her flinch.
Making the best of this odd situation you looked the Lock-Lady over, trying to figure out her 'mechanism'. Her body grew hotter at your touch, having started out ice cold it almost felt like touching a slick, metallic human now. The sheepish voice of Brunhilde asking "Roger? What'cha doing, exactly? Doesn't look like the kind of lockpicking we want to see you doing." Meredith snickered at that, amused by the sight of your face. Looking at yourself in the reflection of the Lock-Lady's belly you realize your cheeks are beet red. You hadn't even noticed.
Brunhilde looked about as embarrassed as you felt. Her chest rose and fell with heavy but controlled breaths. Meredith on the other hand seemed more amused and intrigued than anything. She rubbed her chin as she thought out loud "You know, we've so far seen a lot of subtle hints that the owner of this place is a sexual deviant. Remember the dream journal we found, Brunni?"
Brunhilde laughed awkwardly at that, but nodded in agreement "Ah, ya. The one about the succubus assisted dreams, right? It was very...descriptive." Meredith grunted, pointing to the lock "I think he also mentioned the idea of using his 'prowess' as a way to lock his most precious belongings. If I'm right - and the way this lock is looking at you right now is telling me I'm right, Roger - you have to...well, unlock her through pleasure."
"Uh...okay? I know you two keep calling me 'Lock Lover' and other things about me being intimate with locks when you think I'm sleeping, but this is a bit much for a joke, don't you think?" you replied with a wry chuckle as you squeezed the Lock-Lady's hips. Brunhilde averted her eyes as Meredith snickered, cooing "Oh I'm dead serious you sneaky bastard. You'll have to actually get hands-on with this lock and at least make her lose the willpower to keep the vault locked."
That notion made you swallow. You stared at Meredith's delight, then to Brunhilde's disgusted-yet-aroused facial expression all the way back to the Lock-Lady at your mercy.
After gathering all your courage you began
