The Next Morning, Closing the Cage

The next morning, Lisa rose from bed with a yawn, throwing the covers off with a single motion. The cold air prickled her skin, but she ignored it, rubbing the sleep from her eyes, she turned and checked the clock. She still had some time before she was expected at college. For a moment, she snuggled back down, drawing the blanket over her body. The covers touched her naked skin, and she frowned.

Naked?

Why was she naked...?

She sat bolt upright as her memories rushed back, banishing sleep with a burning whip of shock, desire and lust. She felt her mouth go dry, and she quickly reached for the rulebook, fingering through it until she found the new rules she had written last night.

Yep. There they were.

What the hell had she been thinking? Well, the answer was obvious, she hadn't been! She'd been too caught up in the lust and awe of the day before, riding high on her fetish having finally been fulfilled in a way she could never have hoped. So she had pushed further. Luckily, she could just erase them now she was in her right mind....right?

She paused for a long moment, her finger hovering over the rules, as if she could wipe them out by **** of will alone. But if this was indeed the case, then she may still have failed. For a moment later, she lowered her fingers, biting her lower lip, a faint flush on her cheeks.

Maybe it was okay to let them ride for just one day

Just to...just to see what they were like?

She sighed, knowing already that the battle was lost, and she didn't have much time anyway. She kicked aside the covers, and stepped out onto the floor, feeling the unusual experience of the cold air against her naked chest and groin. She didn't usually wear a bra to bed - that would have been hideously uncomfortable - but she did have a nightshirt that she tended to use, and her panties usually remained on as well. Last night, however, she had fallen asleep totally nude. As if to give herself a small taste of what would be waiting for her in college the next day.

She moved to the end table beside the bed, and grabbed her collar, then to her closest wardrobe, which she opened to reveal her clothes. They were set out, organized for each day she would need them. Panties, bras, shirts and so forth, all neatly arranged and set out. Diana sometimes mocked her for it gently. Of the two twins, it was her, the bratty, younger one who was the more organized instead of the studious older one. But it had always been something that Lisa had liked to do, to tidy, to bring order to things. She liked to see mess contained, controlled and removed. It made the world so nice and so neat.

She paused for a moment, then turned away from the closet, closing it with a wooden thud. Judging by the clock on the wall, the college was already open, though it was not yet time for any classes. Therefore, she was technically in the role of a ****, and not allowed to wear clothes. She sighed, though whether from regret or desire, she could not tell. Collar in hand, she moved to the door of her room, opening it and letting the cold air rush in. Lisa shivered, but ignored it as best she could, moving to the bathroom of the apartment she shared with Diana. There, she brushed her hair, and washed her face. The cold water like a sharp shock to her system. When she looked up at herself in the mirror in front of the sink, she saw her own clear blue eyes looking back at her. Her dark hair cut short around the sides and back, but with a fringe that was almost (Though not quite) enough to hide her eyes. Her chest and upper torso were visible as well, her skin pale, and her muscles lithe. She pressed the collar to her throat, and then did it up, looking at herself in the mirror again.

She saw a young woman looking back at her. Desirable and naked. Lisa had never been afraid of her own charm, she knew that many guys wanted a chance to fuck her. She just hadn't really bothered to do much with it. She was always so focused on her own life, on her friends, until the rulebook had fallen into her lap, she simply hadn't really seen much appeal in sex. It wasn't that she didn't like it. As yesterday proved, she loved it. It was just that she had never thought she would get the chance to live up to her fantasies. It had seemed utterly impossible, and without the rulebook, it would have been.

She reached up and angled the mirror, trying to get it to reflect her lower body. Her legs were long and sleek, her stomach trim. Her pussy was trimmed, though not shaven. A soft, dark carpet of pubic hair was visible along the front of her vulva, though it was trimmed low, and quite fine. Her labia was clear, though, as was the entrance to her mound.

She shifted the mirror back to look at herself, imagining the scene from the eyes of someone else. Looking at the collar, the sole piece of clothing she was now allowed to wear.

"Hello, master." She said softly. "Can I greet you with anything? A blowjob? Would you like me to sit in the corner and play with myself until you need me?"

She frowned, seeing her own face in the mirror follow suit, then shook her head.

"No, that doesn't work. How about this..."

She **** her hands up behind her back, clasping them as though they were tied, and schooled her features into an image of defiance.

"No matter what you do to me, you'll never make me admit to being a ****. I don't care how many times you fuck me or make me scream and beg, I'll never be beaten by the likes of you."

Her hands moved back to her side, and she tilted her head first one way then another. Did that work? Yes? Maybe? No?

Who knew being a **** was so hard?

The door to the bathroom shook as someone knocked on the other side, and Lisa almost squealed in surprise. Her sister's voice came through a moment later.

"Lisa, if you're done in there, other people need to get ready too, you know."

Lisa **** herself to breath, waiting for her heart to slow down to a more normal beat. Right, right, sister. Diana. She'd been too caught up in her fantasies again. A sadly common thing with her, even before the rulebook.

"Right, right, no worries, Di!" She called out. "I'm just about finished here."

She moved to the door, and unlocked it with a touch. Then pulled it open, revealing her older sister and twin. Diana was like her in many ways, but visibly different in others. Their body shapes were much the same, lithe with long legs and slender frames. But where Lisa's eyes were blue, Diana's were hazel. Her sister had longer hair, it flowed down to her shoulders, and just a bit beyond. She was currently standing in a night shirt, blinking the sleep out of her eyes.

"W-why are you naked?" Diana said for a moment, and then nodded. "Oh right. The rulebook. You're still doing that?"

Lisa gave her a look. Honestly, only an older sister of much experience and practice could take the fact that you had been chosen to be a sex ****, pleasured in front of the school, and then publicly had sex with a boy you now may or may not have feelings for, and express it in a way that made you think it was just a hobby that she vaguely disapproved of.

"I decided to, yeah." Lisa said. "So, um, no clothes for me today. Heh." Lisa gave a fixed grin. I-it's technically college hours, so it should be expected. I have my collar, see?" She gestured to it. "So I should be fine..."

Diana shrugged.

"Your choice." She said simply. "You can do what you want, but do be careful. Did you take Stacy out of it?"

"Of course." Lisa said. "I never expected her to get involved in the first place. The first thing I did was remove her, and make it so that she was never involved at all."

"Thank you." Diana said. "But I'll keep the rulebook in my bag again, just to be sure things don't get crazy again."

"Yeah, that's probably a good idea." Lisa agreed, thinking fast. "Hey, Diana? We should probably head to college separately today. Since I am a...you know..." She gestured to the collar around her neck. "You're not supposed to associate with me. "

"You sure you're okay with that? We have the rulebook, we can make an exception."

"No." Lisa said. "No, I think I am fine. I'll get out of this when I am ready, but I want to experience it first. Like, really feel it. I can't do that if I use the rulebook to make an exception every time it gets annoying. I'm fine. Really."

Diana frowned at her with her patented ''Older Sister is Concerned'' look.

"Really." Lisa said. "I can get out of this any time I want to, and I will soon. I just want to have a little more fun is all. Then, I'll be the responsible one and you can go crazy instead of me!"

Diana sighed, but Lisa noted that she didn't disagree, and wondered what she would do once she got her own turn with the rulebook.

"Fine." She said. "But I am making it a rule that college sex slaves aren't allowed to be **** or molested without the say so of their master."

"Yeah, fine, okay." Lisa said. "Ruin the fun and suspense, why don't you?"

Diana shot her a look.

"Kidding! I'm kidding, sis. Don't need to get so bent out of shape."

"You'd better start packing your clothes." Diana reminded her. "Since if you really do intend to go through with this, they will probably be expecting them in the college, and make sure you've written in plenty of protections for yourself! I don't want to have to spend my day undoing your messes."

Letting the bathroom door close behind her Lisa strode purposefully back to her room, who did Diana think she was, her mother? Yesterday had been amazing, scary yes, and she felt guilty at how Stacy had been sucked in, but how could she properly experience this if she had a chaperone? To find her limits, she needed... no limits. Opening the book, she felt her legs grow weak at the sight of what she had written there, this was such a stupid idea, Diana might never trust her again, to say nothing of the risk she was putting herself into.

''New Rule: This Rulebook will be sealed for 24 hours from the moment it is next closed.''

Lisa Paused, the Rulebook open on the table in front of her. She wanted to try it, to be a ****, and Diana surely wouldn't let her truly push her limits, this was the only option, but still.. she hesitated, book half closed. When the time was up, Diana would undo whatever had happened, and maybe never trust Lisa with the book again, this was her chance. Hastily she erased the 24, and wrote in 48, before slamming the book closed.

Butterflies filled her stomach, there was no turning back, no safety net, no sister watching over her. She hastily scribbled a note, apologizing and explaining what she had done, and hurried out of the house before her sister could confront her.
