Watching Lily's expression was a delight in itself. Her first reaction was excitement, as my punishment promised a way to get rid of the ache that she had been dealing with. But that didn't last for long, and panic joined the mix almost immediately as she looked around.
Even with the wards, the library was hardly the safest place.
"We - we should find somewhere safer," she said quickly, but when she tried to stand up, my hands were around her waist, preventing her from standing up.
"I wouldn't worry about that. You were here for a long, yet no one noticed you other than me. You're clearly in a safe position," I explained as I tightened my grip, chuckling.
She gasped in annoyance - well, as close as she could manage in her excited state. "It's just an aversion ward, it's not safe."
"Come on, genius. It's several interlocked aversion wards, it's very much safe. And, you deserve a punishment even more for trying to mislead me." It wasn't that she was wrong, as the situation was still risky, unnecessarily so, but the temptation of punishing her in a semi-public location was too exciting to miss. "Just make sure you keep your cries low, and nothing will happen."
"N-no silencing wards?" she added, shocked.
"Of course not," I answered. The shock that appeared on her beautiful face was all that I needed to push her even harder. "It's just a part of the punishment, and you can even continue reading your very important newspapers, the ones that you took the risk of ignoring my orders. It's only fair."
I said nothing else, giving her a moment to process the situation. I didn't want her to react in panic, but considered it slowly before accepting. Luckily, my earlier work to make her obedient worked excellently, she stayed on my lap.
"Excellent decision," I said as I pushed her down, and she found herself leaning against the desk, her ass effectively naked for my attention as her skirt rode up, and her thong covered almost nothing.
"What are you going to do?" she asked.
"A spanking is enough to teach you a lesson, Miss Evans," I said, deliberately changing the way I referred to her once more, a deliberate attempt to distance her from her responsibilities even more. "Just count it obediently, and it'll end soon."
"This is… acceptable," she said, though her tone suggested she had much nastier words than acceptable waiting in the line, she was wise enough to keep them back, aware it would only intensify her punishment.
And, while I doubted she was against that, she clearly didn't want the library to be the location for that punishment.
"Very good," I said, her gaze darting enough to make her thoughts an open book. I chuckled as I conjured a wooden ruler, making it a thematically appropriate decision as I landed it on her ass. The gasp she let out was beautiful.
"Don't forget counting," I reminded her as I landed it again.
"One," she whispered, not hesitating before answering… but the sudden rush of passion in her tone surprised me a bit. Maybe she wasn't too far away from submission as I had first thought.
"Good, now lean against the desk so I can work on your ass properly," I ordered. She looked at me hesitantly, but that didn't prevent her from leaning forward, her tits pressing against the magical wood, straining her cleavage even more.
"Two," she whispered as I spanked again. "T-three," she followed, though her stammer was not about the pain. No, it was about where the ruler drifted after spanking her. It caressed against her wet panties, right against the center, triggering her arousal.
Yet, she didn't complain as I played, staying silent as I used the ruler on her ass again. Seeing her rather quick obedience, I decided to push it to the next stage. This time, I hooked the ruler to her underwear before pulling, and it naturally snagged.
"Naughty girl, setting a trap like this," I said, giving a deliberately absurd reason as I ripped off her panties, leaving her pussy naked. "Much better," I said as I caressed her wetness, and the ruler landed on her ass.
"T-that's too much-" she tried to complain, only to be interrupted by a loud cry as it landed on her ass once more, this time extracting an even bigger jolt of pain.
"Come on, Miss Evans, it's just a punishment," I said. "And start over."
"One," she said as I used the ruler on her ass once again.
"Good girl," I rewarded her, caressing her entrance as I said that, making her shiver desperately.
"T-this is… wrong - two," she said, complaining without missing the count.
"Oh, sweetie, on the contrary. It's only right after you suffered all that time without a man's touch. Look at the way you dressed in a library, and that's when I just helped you yesterday with your toy after catching you peeking at me."
"That's not what - three - happened. I was just - four - trying to understand where I was," she explained, trying to excuse her behavior.
She wasn't very successful.
"Sure you were," I said, not bothering to argue against it. "So, you're saying that you'll stop me if I pull my cock out and take you in the middle of the library."
"Yes," she answered, determined enough to surprise me. Though that surprise lessened when she completed her sentence. "Not in the library."
"Oh, naughty," I said as I spanked her once again. Shocked by her words, she failed her count once again, but this time, I felt merciful, and decided it was enough spanking. "Very good, let's go back, then," I said and stood up.
I took a few steps forward before looking back, and saw her trying to stay on her feet without falling, but her expression was tight. "Come on, Miss Evans, we don't have all day."
"M-my robe," she whispered. "I need my robe."
"No," I answered.
"W-what do you mean, no," she gasped. "I can't walk around like this, even invisible."
"You lost your robe due to your disobedience. Why should I bother conjuring your new one…" I said, and she looked even more shocked. "And, it's not like you're naked. You still have your uniform."
"My… my uniform," she gasped as she used her hands to cover her body once more. She was not successful, and the earlier loss of her panties didn't help.
I watched in amusement as she shuffled, then conjured two items. One mask, and one chained collar. "Tell you what. Put both of those on, and I'll actually bring you to a room where you can live independently, and even leave my protection if you wish," I offered.
That brought her to a stop. "If you lie about that…" she started, only for me to wave my head.
"No, definitely not," I said. "I'll even help you come up with some stories about your sudden appearance, though I suspect it has something to do with Snape's disappearance."
She took that last part rather quickly, which didn't surprise me. Appeared almost two decades after her disappearance, just as the dark wizard that was famously obsessed with her disappeared… hardly a coincidence.
It also reinforced my decision to let her go. If a night alone was enough for her to escape my control to such a degree, I could hardly continue keeping her in my room forever and hope it would go well.
While she considered my offer, I passed the collar to her. "Why this?" she asked.
"Well, I don't like your son. He's quite arrogant, and not to mention a bit of bully toward the Slytherin," I said, lying shamelessly. Yet, while it was a lie, considering James Potter's history, she had no reason not to believe it.
Especially since anything written about him was highly unreliable. And, since I was the one that sold my story first, it would be believable even if Lily managed to achieve the impossible and met with Harry while he was hiding.
"So, you're doing this to…" she said.
I smiled. "Since I can't stop him in his very important mission, I have to make him pay somehow, right?" I asked. "I was planning to seduce his girlfriend, but he dumped her before I could do so. Luckily, his sexy mother achieved the impossible and returned from death…" I said. "Even better, she was horny enough to masturbate in my room and give me the idea," I added, enjoying her blush.
Somehow twisting the situation to blame her was particularly tasty.
Her mouth opened in shock, but she said nothing, thinking desperately. "Good girl," I said as I took a step forward, and used the ruler on her thigh. "Now, why don't you put that beautiful collar on and we can walk. And, look at the bright side."
"What bright side?" she grumbled, split between her maddening arousal and my daring request.
"No one thinks you're alive, so even if they see you, no one would suspect the truth," I reminded her. "So, there's no danger to your reputation. Just do that little favor for me to quench my desire to revenge, and we can work on defeating the dark lord together."
She trembled, her face reflecting a confusing rush of emotions, venom of pure anger mixing with the poison of desire… I was pushing my luck too much… but what was life without some risk.
"You win," she growled as she put her mask on, a small crimson piece that covered the upper half of her face.
"Don't forget the collar," I reminded her. She growled, but she still put that on, her persistent and recently stoked arousal doing wonders to push her into a horrible decision.
She closed her eyes, and the collar clicked around her neck…
