Violet locked the front door of the library. It had been a long day, full of frustrations and rule-breaking patrons. In particular, she had caught a couple kissing in one of the study rooms and thrown them out. The rules were clear on public displays of affection - the library was a place of scholarship, not a make-out nook.
To make matters worse, the couple had accumulated a number of books which she had to put away. Their subject matter was sexual in nature, covering intercourse, fertility, and pregnancy. Under other circumstances it would not have been a concern, but in the context of the couple's actions, it led Violet to wonder what they would have been doing in half an hour, had she not interrupted them. She had done her best to keep such undignified thoughts from disrupting her work, but they were remarkably persistent.
She checked each of the study rooms and, finding them empty, returned to her office to get her bag and go home. She entered and flipped the switch, and found that her office was occupied.
The couple she'd thrown out were waiting within. The man sat on the edge of her desk, watching Violet as she entered. The woman stood next to the door, and shut it quickly before Violet could react.
"What are you doing here?" Violet demanded. "The library is closed, and you were asked to leave."
"We just had a few questions about the library's rules," the woman said, "and we wanted to talk to you about them."
Violet glanced between them. She was only five foot three, and barely topped one hundred and ten pounds, so both intruders were more imposing than her. The man was blond and wiry; the woman was willowy like Violet, but with brown hair and a bit more muscle.
"You'll have to come back during normal library hours," Violet said primly. She took a step toward the door, but the woman didn't budge.
"I'm sure we can resolve these questions before long," the woman said. She theatrically placed a pair of horn-rimmed glasses on her nose, cleared her throat, and opened the library's rulebook.
The man grabbed Violet from behind, wrapping his arms around her, and pinning her arms to her sides. "Hey!" Violet said. "Unhand me!"
The woman flipped through the rules, then stopped to point at a passage. "First off," the woman said, looking sternly at Violet, "you're wearing your library uniform."
Violet glanced down at the polo shirt, tan pants, and black shoes. "I am."
"You're only supposed to wear it during normal library hours," the woman said, indicating the open page. "That's what it says in section three."
"We can't have her breaking the rules," the man said. "We should strip her."
"What?" Violet gasped, an instant before the man picked her up and set her down on her desk, knocking a stack of papers and a framed picture of a calico cat to the ground. The man moved to one side of the desk and held Violet's ankles. Violet sat up, trying to push the man off, until the woman set the rulebook down on a podium and pushed her down.
"What are you doing?" Violet demanded.
"We're making sure that you follow every rule," the woman replied promptly.
The man quickly unlaced Violet's shoes and dropped them.
"The socks are part of the uniform too," the woman added. The man pulled them off as well. Violet kicked, but she was clearly unused to kicking. The man caught her foot and admired it for a moment before leaning forward.
"This is most improper and - hey!"
The man unzipped her pants and began sliding them off. She squirmed, but the man continued pulling, until her long, pale legs were exposed, leaving only her plain white panties on her lower half. She raised her knees, keeping her legs close together.
As the man held her hips, the woman grabbed the bottom of Violet's dress shirt and pulled. It broke free of her shoulders and slid up her arms, leaving Violet in her underwear. She was pale and skinny, with a few scattered freckles and her black hair tied in a bun.
"How dare you," Violet said, blushing deeply. "It's not proper for you to see me like this. Now give me back my clothes-"
"Hold on," the woman said, holding up a hand and raising her eyebrows. "You're saying this isn't proper attire?"
"I guess we should take these off too," the man said, and reached for Violet's panties.
"Nooooo!" Violet squealed, as the man pulled. Violet tried to open her legs at first, to keep her panties from sliding off, but once the man had pulled them down far enough to expose her pussy she pushed her legs together. The man dropped her panties on the ground and gazed appreciatively at the curly black hairs of her bush.
The woman reached behind Violet while she was straining to get up and unclasped Violet's white cotton bra. She held one of Violet's wrists down with one hand and pulled the bra off with the other, despite Violet's attempts to stop her. Violet's small, firm breasts were freed, and her nipples reacted to the sudden air.
"How dare you!" Violet demanded.
The woman pulled out Violet's hair pin, and her long black hair cascaded down. "We're just following the rules."
"You most certainly are not! Now let go!"
Unexpectedly, the man and woman both did so. Violet covered her vagina with one hand and her breasts with the other. She sat up, indignant but fearful. The man gathered her clothes and piled them at his feet, next to the door.
The woman cleared her throat, and adjusted the glasses. "What's next," she said, flipping through the rules. "Aha - Any items or articles of clothing left in the library should be left in the lost and found box."
The man found the bin, in the corner beneath a framed picture of a tortoiseshell cat, and dumped Violet's clothing into it. He looked down at his own clothing and stroked his chin, as if coming to a realization. "I suppose that means our clothes too," he said, and began to strip.
"What..." Violet said. The woman stood at the door, blocking her escape, as the man dropped all of his clothes into the box. As he revealed his wiry frame, Violet could not help but notice his penis as it sprung free. He saw her looking and stroked himself; she moved back apprehensively.
"Swap?" the woman said with a smile. She began to strip, too, while the man stood at the door. She slowly unbuttoned her shirt and pulled off her bra. Her breasts were slightly larger than Violet's, with dark nipples. As she watched Violet, she traced her fingers around her areolas, spiraling in until she touched her nipples. Then she took off pants and underwear with a single move, and turned back to Violet with her legs slightly spread, wearing nothing but the horn-rimmed glasses. Violet found herself staring at the woman's naked pussy, and she swallowed past the lump in her throat.
"What are you doing?" Violet asked.
"We're just following all of the rules," the woman said. "Don't worry. We're not going to hurt you." The woman consulted the rulebook once again. "Hmm," she said. "It looks like now we're supposed to make sure that all of the library's facilities are in working order."
"Better get started," the man said.
The woman nodded. She leaned in and kissed Violet on the lips. Violet's experience with kissing had been rather limited, but the woman's lips were soft and gentle; she explored Violet's lips, and Violet held still, shocked into inaction, her body growing excited from the warmth of the contact. The woman's tongue pushed inside Violet's mouth, and she reacted.
"Mmph!" Violet said. She drew back, and the woman pursued her, forcing Violet back down onto the desk. The woman held Violet's wrists above her head and leaned in, kissing her neck and her ear.
"No!" Violet shouted. "What are you- aaah!"
She looked down. The man had begun kissing one of her breasts, starting at the edge and working his way in. He kissed her nipple, and she gasped. "Stop!" she said.
"We need to check all of the library's facilities, including yours," the woman whispered. She climbed onto the desk, knocking over a picture of a black cat, keeping Violet's hands pinned all the while.
"After all," the man added, between kisses, "you can't check these by yourself."
"We care about your facilities," the woman said quietly. She leaned in and kissed her tenderly on the lips. "They're lovely."
"They are," the man said. "You should enjoy them."
Violet squirmed, trying in vain to get out of their reach. The man's attentions in particular were arousing her, to the point that it took significant effort not to moan out loud.
The woman adjusted her position, leaving her knees wide apart. She shifted Violet's wrists, holding both with one arm, and began to gently rub her pussy with the other. The man moved to Violet's right breast, kissing the sides, then licking and nibbling at her nipple. Violet moaned for a second, then stopped herself.
"It's alright," the woman said, gently, almost lovingly. "You can moan if you need to."
"No," Violet whimpered. "Please, get off me."
"We'll have to see what the rules say next," the woman replied.
As close as she was to the woman's bald pussy, Violet could see the woman pleasuring herself and smell her arousal. That, in turn, further excited Violet. The woman smiled down at them both - Violet, and the man kissing her breasts.
The man didn't stay put, though. He began kissing a path down, along Violet's ribcage and down her stomach. Violet squealed when she realized where he was headed, and tried to keep her legs closed. The man pushed his knee between hers, forcing her legs apart, then began kissing her thighs.
"Nooo!" Violet squealed. But the man pressed on, moving inward until he reached her pussy lips. He ran his tongue along her cleft, then pressed his lips against hers. She felt his tongue flicking against her clitoris, and then felt an exquisite sucking sensation on her lips. Violet could feel her own lubrication mixing with the man's saliva. She was mortified, yet fascinated, to know that this man was sexually exciting her.
"Looks like your facilities are working pretty well," the woman said. "Although we need to see if you can cum, too."
"No! I've never done that with anyone," Violet said, torn between excitement and apprehension.
"Oh, I think you will," the woman said. "It will be lovely."
Violet tried to prove the beautiful stranger wrong, but it was a growing struggle. The man was taking her higher with each moment. Her pussy was dripping wet, her heart was racing, and her pale skin was growing flushed.
"Oh," she moaned. She shook her head, as if to escape her own arousal.
"It's okay," the woman said. She caressed Violet's cheek, her hand wet with her own arousal. "He's good at this. Just let him make you cum."
