Examination

"Hmm. David said, and Diana watched him for any sign of what he was thinking. But he gave no clue, and a moment later, Lillian stood up, wiping her fingers on her dress.

"I think it's best if the two of you are examined for both types of piercing." David said, "Just to be safe. Why don't you start with Diana there? Lisa is still kind of...busy."

The sound of her sister sucking David's cock was still filling the room, and Diana watched as Lisa continued to move her head back and forth, running her tongue along his member, her lips closed around it, sucking at it almost greedily. David was clearly enjoying it by the way his body was moving, his fingers were still wrapped about her nipples.

I don't have to do this. Diana thought to herself. Lisa is the one who is the ****, not me. There are no laws making it so that I have to submit. I could leave right now if I wanted to.

But doing so would be a betrayal of her sister, and of the bond that they shared. It would mean that she was willingly leaving Lisa to suffer whatever punishment David deigned fit, and no one would come to her aid. The only person who could help her was Diana, and that meant playing along with David's game for now, even if it meant her own personal embarrassment.

This was what she thought as her hands moved to the jeans she had put on earlier, undoing the button and then the zip. In front of David, Lillian, Stacy and Lisa, Diana shrugged off her jeans to reveal her panties, which lasted only for a moment or so before these two were removed. There was no point in going slow, she decided. If she did, it would be a sign of weakness, a sign of fear, and David would be watching. So she did it as casually as she could, hooking her fingers into the band, and drawing them down over her legs until her womanhood was exposed to the cold air. Diana gulped, feeling the waves of weakness and hesitation travelling down her back as she bared herself to her enemies. But of course, Lisa would have endured far worse by now, so she really had no cause to complain.

David had seen her naked before, back during the first class after they had started the whole **** thing. But that seemed a lifetime ago to her now, and Lillian had never seen her nude at all. The black-haired girl cackled to herself, soaking in Diana's embarrassment.

"I didn't know you were shaved down there!" She said, "I suppose that makes things easier for you, eh? When you get made into a ****, we won't have to do it ourselves."

"I'll remember you said that, Lillian," Diana said, her voice low, "and all of the other things you've said and done too. Mark my words, even if it's not happening right now, there's going to be a reckoning for it later."

"In the meantime..." Amy said, again, seeming to be disturbed by the topic of conversation, "Please get up on this table. I'll have to strap you in, I am afraid, and then I'm going to have to examine your vagina to see what sort of piercings it can take. I apologise, but since that will involve touching and feeling, it will probably be stimulating for you."

Diana said nothing. her throat felt dry as she moved, the passage of air between her legs an acute reminder that she was unclothed. She could feel the tingles running up and down her body, a certain tightness in her womanhood that warned her of arousal. Humiliation stained her face as she climbed up onto the table. The plastic and metal felt cold against her skin, making her shiver. The straps were felt rough as Amy drew them across her lower legs. Two across her inner thighs, and two across her ankles, being strapped to the table was one of the most humiliating things she'd ever done. She wiggled a bit, but there was no give, and she was especially mortified when Amy pressed down on the table, and it split into segments, allowing her to move Diana's legs further apart, spreading her unwillingly and opening her to the world. She tried not to show emotion, even as she heard Lillian chuckle at her exposure, even as she heard Lisa still sucking on David's cock. Her sister pleasuring the man who was humiliating them both.

David grunted, and came a moment later. Lisa made a face of distaste as she felt his cum fill her mouth, but knew better than to spit it out. She swallowed it, even as it made her feel sick to her stomach.

"That's good, ****." David said, as he did up his trousers again, "You're getting much better at this. But don't forget the final step. You have to thank me for my gift."

Lisa flushed red and looked down towards the ground again. The seconds grew longer, and she said nothing. David waited, slowly growing more impatient.

"You know that if you don't do it, I'll just make your sister suffer for it, right?" He said, "She'll do anything I say so long as its for you. What joy, to think that I got two for the price of one, and twins as well! If you don't say it, I'll fuck her right here and now, or maybe Lillian will let me borrow innocent little Stacy, eh?

"Thank you..." Lisa snapped the words out, almost as if she wanted to bite them back as they left her mouth.

"For what?"

"Thank you for cumming in my mouth....master..."

"Good! Very good! You see, Lisa? You can be taught! This little defiance act of yours is so tiring. why can't you just give it up and be the whore I already know you are?"

"Fuck you, David."

"Tut-tut. That's master to you, ****. Just for that, how about another punishment? Let me see... All right, I want you to sit on that floor and spread your legs. You're to touch yourself, but only your pussy. I've seen how you like to stimulate your tits as well when you cum. I want you to climax to the sight of your beloved sister strapped to a table getting examined, so you're not allowed to look away. Understand?"

"I understand..." Lisa glared at him defiantly.

"Well, then get to it!"

The younger twin had ****, as everyone watched, she sat on the cold floor and spread her long legs as far apart as they would go. Her pussy was already wet, David had been playing with her breasts while she sucked him off. Hating the fact that she was getting off on the humiliation she felt, Lisa's fingers started to stroke her mound, moving back and forth as they found a rhythm.

Diana tried to block out the wet sounds that Lisa made, her womanhood already anticipating something that she was now being **** to deliver. As Lisa started to moan and pant, Diana threw her head back, ignoring how utterly helpless being in this position made her. She could feel Lillian's eyes on her pussy, and knew that the other woman would never forget this, nor allow Diana to forget this, but it was made all the worse a moment later. Amy stepped close to her body, close enough that she could see the other woman's focused eyes. She was trying to block out what was happening behind her. The rulebook was making her see it as right, but she didn't like it at all. She was focusing on her work. Diana felt her breath against her naked skin as Amy knelt down, peering at her womanhood.

Her nerves went taut, and her senses waited in tense anticipation. The only sound was the moaning of her twin as she was made to pleasure herself. Amy reached out slowly, using one hand, she gently traced a finger across Diana's Vulva. The touch was slow and gentle, and Diana felt herself shifting against the bindings as her skin started to light up, the wake of Amy's finger tingling in aching desire. But Amy didn't notice or didn't care. Instead, Diana felt her start to touch and prod her vulva, spreading fingers around it as though to measure the shape. She pressed against it, pushing downwards with enough **** to make Diana shudder, and see stars, then moved her fingers and did it again. She traced the whole area, not once but twice, and by the time she was done, Diana's legs felt quite weak. Only then did she move lower, the tickle of her breath giving away how closely she was pressing her face inwards. Diana felt that she surely didn't need to be that close, did she? But she was, and she was examining every inch, every scrap of flesh. Diana mused that if she hadn't been shaved down there, Amy probably would have insisted that she become so.

This sort of attention, unbending, unwavering and directed right at her made Diana feel all the more helpless. The straps which held her in place bit into her skin, and there was a tiny orb of tight heat growing between her legs. She tried to shift, but could not. She tried to cover herself, but could not. She was trapped, utterly exposed, and being examined like she never had before in her whole life. Even the guys during the test to determine the new **** had not paid as much attention to her body as Amy was now.

Next, Amy started to reach out, running one finger down her slit, and then another. The feeling was ****, light and gentle enough that it didn't really satisfy her screaming body, but strong enough to hint at more. She shuddered, gasping and trying not to feel how hard her nipples had gotten, and how horny she was right now.

Lisa was moaning now, her hands moving faster. She too was watching as Diana was being examined, both dreading and anticipating her own turn on the table, while at the same time the sight of the careful examination was used as fuel for her self debasement.

With a finger on each one of her lower lips, Amy spread her open, forcing Diana's outer layers aside and exposing her inner core. She gulped and gasped as Amy's fingers traced a careful path through her folds. Amy wasn't trying to pleasure her exactly, but she seemed to need to know every inch of Diana's pussy to answer the question she'd been asked, and so, Diana was **** to sit and endure as she was touched in different places, with different angles, weights and approaches. She tried to pretend that it wasn't firing her blood, that her toes weren't curled with pleasure as the humiliation and desire melded into a fog in her mind.

Even as she put up her own resistance, Diana could hear Lisa's moans growing more and more urgent, her fingers moving faster and faster. Her face was flushed red, but she wasn't allowed to look away, her legs were spread away, and everyone could see how wet she was. She was bucking back and forth, her arms and legs were trembling as she felt the building pleasure.

Diana's clit became a tiny point of fire and tightness, she could feel it, oh god could she feel it, growing more and more concentrated, aching to be touched, to be seen. The sheer power of the desire swept through her, surprising her even as she battled against it. But, the clit was exactly where Amy needed to go next, and thanks to Diana's arousal, its location was obvious. Diana's whole body jumped and shuddered, her heart pounded as Amy's fingers closed around her clit, pressing down with enough weight to **** it out of its hood. The nub of flesh which was the centre of her sexual existence sat for a moment, totally without protection.

"I'm really sorry about this, Diana." Amy said, bending forwards, "But I need to make sure that you can actually take this piercing, so I need to know about your clit."

Amy's fingers closed around the naked clitoris itself. The sensation of being touched there was almost too much, and Diana tried to kick out, gasping as a moan tore itself free from her mouth. Amy's fingers pressed against the naked flesh of her bud were one of the most intense things she'd ever experienced, especially when the other woman started to slide her fingers up and down, checking the form of her clit, the structure behind it, and how sensitive it was. Diana could only throw her head back and try not to shudder, but it was a losing battle, and before long, Lillian felt moved to comment.

"Look at her, she's getting off on it!"

It was true, she was getting off on it, even though she was trying not to. Each touch of Amy's fingers sent a shockwave racing through her body, her nerves screamed for more, even as her limbs shook. She felt weak and helpless, lying on the bed as her most private area was examined so totally, so completely. As though Amy was going to put it in some medical book. As if she needed to know every single detail.

The examination seemed to last for eternity, but eventually, as Diana lay weak and shuddering, Amy withdrew. She took off the gloves she'd been wearing, and looked towards David.

"As far as I can tell, she's viable for both types of piercing." She said. "What about you next?"

Amy still sat on the floor touching herself, but with David's permission, she was quickly strapped into a table next to the one which still held Diana, and underwent the same in-depth examination. Lisa was much louder though, owing to the fact that she was already so much more sensitive, and to her deep shame, could not hide her own arousal.

When it was done, both sisters lay panting side by side as Amy announced that both were viable for either of the piercings.

Diana expected David to announce that they would both get the clit piercing, the most overwhelming and stimulating choice. It would be right up his alley to get off on making the two of them so helpless even in their own bodies. But she was wrong, he didn't leap right to that. In fact, he looked like he had another idea entirely.
