Reddit, I am at my wits' end.

I want to preface this by saying that I love my daughter. She's technically my step-daughter but I'm the one who put in the work. Anyway, she's been calling me Mom for most of her life, so the point's moot. I admit that I haven't always been the most patient, but I want what's best for her and I'll fight anyone who stands in the way of her success.

It's just that at this point in my life, I thought I would be an empty-nester, spending my weekends on the couch with a glass of wine in one hand and a spicy novel in the other.

Unfortunately, Cassie isn't the college type. Don't get me wrong, she's smart enough to get a degree, but it's like she can't help but freeload. I swear, every other sentence out of her mouth starts with "can I have" and ends with a huff of annoyance.

Things got worse when her father went overseas. She talks back to me near-constantly and I've started to notice my things being moved or disappearing altogether. At first, it was a comb here, a couple earrings there, the odd pair of shoes. Nothing I couldn't live with, but annoying all the same. Sometimes I could swear that my underwear was also disappearing, but I wasn't sure. Then, one day, I came home from a long day at the office and my vibrator was in the wrong place. I'm a bit of a neat-freak so I noticed immediately.

That's when I bought a nannycam. It was a simple affair, a tiny camera embedded in a book on my shelf. A precaution, just on the off-chance that something really was happening.

You can imagine my vindication when I saw Cassie enter my room last Tuesday. I was halfway through a manuscript when my phone notified me of the intrusion.

She was still in what passed for pajamas (underwear and a big T-shirt) as she strolled lazily into my room. I watched with equal parts fury and fascination as she stopped to paw through my hamper, inspecting and tossing aside articles of clothing before she found it: a pair of lacy blue panties. I let out a gasp in my silent office as she raised them to her face, closing her eyes as she breathed. Then she turned and walked out the door, still holding my underwear.

I've re-watched the video at least 12 times since then. There's no doubt about it, she has been taking my dirty underwear. I can only guess what she's using them for!

I haven't told you the worst part about all this. As I sat at my desk chair, staring at my phone in total disbelief as my daughter pressed my soiled panties to her face, I was wet. Wetter than I've been in decades, I think. It's been a long time since I've seen my husband, longer still since he's touched me.

I can't even bear to look at Cassie. Every time I see her faux-sweet smile, the infuriating quirk of her brows, the way she runs her fingers through her hair as she asks me for cash, I can only see one thing: her face pressed between my legs.

What the hell am I supposed to do? I'm at my wit's end.

Update 1

Hi everyone. I read your comments and I've been considering what to do. I've tried casually asking her if she's been "borrowing" my things, but I was met with a blithe smile and outright dismissal. It's like she's taunting me.

I'm ashamed to admit, I've been reading the posts here and touching myself, thinking about my daughter in all sorts of compromising situations. It's become an obsession and I'm ashamed to admit that I've been purposefully keeping my underwear on while I masturbate, thinking about her discovering the soaked panties in my hamper and taking them into her room. God, even typing that right now makes it hard to sit still.

I endured a week of this torture before I caught her again.

I was in my car when I got the notification. I nearly screamed with frustration when I saw it, hands gripping the wheel as I willed myself to keep driving and not turn right around.

As soon as my office door closed, I pulled out my phone. It's annoying, she wasted no time in getting into my room.

In the recording, she walked straight to my hamper, her previous laziness replaced with urgency. It didn't take her long to find what she was looking for, I'd practically laid them out for her – the panties I'd masturbated in before leaving for work. Just like before, she pressed them to her face, her eyes slipping closed as she breathed. Then she turned and, instead of going to the door, she walked to my dresser. I could feel myself clench, even as my blood boiled.

The little thief wasted no time in getting out my wand vibrator, confirming my suspicions that she's been doing this for a while. Then she got into my bed, laid herself on my pillows, and began to get off with my vibrator.

I just couldn't help it. I pressed my back against the door and pushed a hand beneath my skirt, watching her press my panties to her face as she trembled and shook. It didn't take either of us long, she came with a silent scream, writhing and bucking on the soundless video, and my legs nearly gave out from beneath me.

It's a good thing that I always carry wet-wipes in my purse.

After that, my mind was made up. I know you've given me some good ideas on here, strategies for communicating with her, but you didn't raise her. You haven't had to deal with her excuses, the whining, the lies. I know how to deal with a brat like her.

Update 2

Hello again. I know it's been a little while, but I wanted to wait until I had a real update. The past couple weeks have involved watching (and getting off to) nannycam footage, just waiting for a pattern to emerge.

You see, my daughter is a creature of habit. Even if her routine involves surfing the web, playing Call of Duty, and the occasional girl's night out bar hopping, it's fairly consistent.

All it took to carry out my little plan was to take a day off work, park around the block, and walk home with my phone in hand.

My timing was impeccable. I caught her mid-stride, my vibrator in one hand and dirty panties in the other. She didn't even hear me coming, even though I swore my pounding heart would give me away.

I crossed my arms as I watched the blood drain from her face. I would have stood there for minutes as she stuttered and came up with excuses, but when she actually tried to hide my things behind her back, I was done. I crossed the room quickly, grabbing her wrists as she whimpered. I marched her to my bed and pushed.

She fell half on the bed, her knees sliding to the floor, and tried to stand back up, but I stopped her by placing one foot onto the small of her back. She's lucky I wasn't wearing kitten heels that day.

Then she started apologizing. "I'm so sorry, I don't know what I was thinking, I didn't know you'd be home, I was just curious," blah blah blah. A string of bullshit.

Finally, I told her to shut the fuck up and she fell silent.

"What am I going to do with you?"

"M-Mom, I'm not—"

"I don't care, Cassie." I gestured for the vibrator and she handed it over reluctantly.

"And my panties, you little brat." She turned beet red as I took them, her fingers hot and trembling.

"Open your mouth."

She did, then let out a muffled squeak when I stuffed my dirty panties into her mouth.

"So you want to use my things without asking?"

Her pupils were wide and her breathing became shallow. She shook her head.

"No? Then explain this." I retrieved my phone and held it in front of her face, her numerous crimes cataloged in HD.

She tried to speak around he underwear, but I hushed her. "I don't want to hear your lies, baby. I just need to know one thing."

I pulled her shirt up, revealing the wet spot on her underwear, relishing the way she squirmed under my gaze.

"Do you want this?"

She drew in a shuddering gasp and nodded, squeezing her eyes closed.

I reached down and ran a hand over her spine, stopping just above her waistband. "Show me, then."

She wasted no time, reaching back to pull her underwear down.

I sucked in a breath. I'd never seen her naked, not even in the videos. She was trimmed and neat, pink folds dripping with need. It had been so long since I'd fucked a woman and I had to take a moment to collect myself.

"Good girl," I said, watching as she clenched at my words.

I moved my hand down, sliding over her ass to cup her pussy. "You're so wet," I murmured.

She let out a whimper as I pulled my hand away, then a moan when I pressed my vibrator against her. She tipped her hips up, ears turning red as I laughed at her desperation.

"Hang on, you little brat." I removed my heel from her back and sat beside her on the bed. I switched the vibrator on and she let out a sob of relief.

"Grind on it, there you go. Show Mommy how you come."

That did it. I regret not buying a camera with a speaker because I wasn't prepared for how loud she was. I hoped the neighbors wouldn't hear. She screamed around the wad of underwear, tears forming in her eyes as I increased the pressure, wringing the pleasure from her until she twitched and winced.

"Had enough?"

She nodded and I pulled away, giving her relief. The gag came out too and she gasped raggedly.

"Next time, just fucking ask."

She laid there for a second, then raised her head.

"I'm not interested in your excuses."

She shook her head. "Can I? Um." She was staring between my legs and I became acutely aware of how wet I was. She could probably smell me, the little beast.

"Fine." I stood and unzipped my skirt, holding back a yelp as she reached underneath it to pull down my tights. "Get on the bed." I ground out.

She obeyed, a sly little smile forming on her lips. I considered kicking her out, making her listen at the door as I finished myself off, but the need to wipe that grin off her face became all-consuming.

I arranged myself on the bed and she lurched forward, her hands and lips a flurry at my legs, hips, and thighs. She licked a stripe up my inner thigh before I twisted my fingers in her hair and pulled.

What she lacked in skill, she made up for in enthusiasm. It was a battle keeping her in the right place at first, but with a few yanks and a well-placed heel to her thigh she figured out what she was doing.

Honestly, at that point I was so pent up I probably could have come from a stiff breeze. Her excited lapping was more than enough and in less than a minute, I was nearly there. I flexed my thighs around her head and she moaned against my pussy, her arm moving beneath her as she got herself off again. That was it for me. I pinned her face as she continued to lick, pressing her against me hard as I rode out my orgasm. I don't remember the last time I've come that hard.

As I caught my breath, I could hear the wet sounds of her coming down off her own orgasm, her fingers pumping lazily. I released her and she lay her head against my leg, a small smile playing at her lips.

"What did you learn?" I asked when I was finally able to speak.

"Don't steal your stuff." Her voice lacked her usual petulance and I felt a thrill of self-satisfaction.

"And?"

She looked up at me then, her wet face open and serene. "To ask you when I really need something."

"Good girl." I said. I'd have her well-trained in no time, I could feel it.
