I gathered myself and left the library. I wiped some cum that was trickling out of my asshole and down the inside of my thigh. I stuck my hand out and wiped it on the wall as I walked down the hallway.
"You're going to be my dog." Rita hung behind as everyone else left, and was giving me a ride home. "Do what I say, and don't whine or protest."
"What if I don't want to follow orders?" I challenged. I actually wanted this, but I needed to hear her say it. She smirked.
"You belong to me now. You're property. Property doesn't have opinions or thoughts," she said as she raised her right hand to my mouth, "and property doesn't have agency." Then, without warning, she took her four fingers and shoved them into my mouth. She was pushing them in as deep as she could. I gagged as I felt her nails scratch their way towards my esophagus. Then she pulled her hand out, thick ropes of saliva stretching from her hand like the way cheese pulls away from pizza in commercials. She held it up, and then with her left hand, roughly grabbed my hair from the back of my head, using the leverage to forcefully turn me around. She held me up against a row of lockers.
"Arch your back. Stick your ass out," she ordered. I complied and she threw back my skirt and, still holding my head against the lockers, put her right hand on my pussy. Her drool-covered hand on my wet snatch sent shivers racing up my spine. "Have you ever been fisted?" I shook my head. She took two or three fingers and started penetrating my cunt slow, but powerfully. She then cupped her hand and started twisting it into me.
"Ow. Ow! I think my pussy is too tight. I don't know," I said. She responded my slamming my head into the lockers.
"Shut the fuck up!" she shrieked at me.
"I'm sorry!" I apologized. She slammed my head into the lockers once more.
"Don't be sorry, be quiet! Dumbest dog I've ever owned." She kept twisting her fist into me, and I could start to feel it break through. I held my mouth as tightly shut as possible, trying not to make too much noise as she painfully corkscrewed her hand into my axe-wound.
"C'mon, take it you bitch. Push down!" she demanded. She was right on the cusp, so I put my hands on the cold metal lockers in front of me and pushed backwards. When she felt me push, she thrusted harder and I felt her knuckles drag across the threshold of my vagina, and then I eased down onto her wrist. Her whole fist inside me.
"Oh yeah, you're such a fucking whore," Rita spoke directly into my ear. The feeling was intense. She pushed and pulled her fist, and the sensation of her wrist sliding in and out of me with her fist rubbing the roof my vagina was overwhelming.
"Holy fuck, that's amazing. Fuck me! Fist fuck me harder!" I screamed in ecstasy. She was buried in my cunt up to the middle of her forearm, pushing and pulling fervently. I couldn't see or hear anything. I was being fucked silly.
Rita was down on her knees now, giving her a better angle to pulverize my sodden cunt. I was moaning in a voice deeper than I've ever even spoken with. I thought I was going to pass out.
"Fuck. I'm gonna cum," I managed through a delirious haze. She gave me a few more quick pumps and then, right before I couldn't stand it, pushed in as deep as I could. Nearly up to her elbow.
"Ooohh, gguuuhhh. Fugging goddamnit." I couldn't form words. And then she pulled her arm out, and I just fucking exploded. My legs started quivering as I squirted out of my pussy like someone just broke open an hydrant. Rita laughed. I tried to grab onto something in front of me, to steady myself. Rita shoved four fingers back into my drenched pussy, found the roughest spot inside of me, and started hammering away like a goddamn jackrabbit.
"Oh shit, fuck, fuck, fucking fuck!" Rita started laughing like a child that just got a new toy as I continued to gush my cunt juice all over her.
My legs buckled, sending me to the floor in an epileptic fit. I tried to speak but could only manage a single low moan that poured from my throat like a siren. My legs shook and I held onto my pussy like I had sprung a leak.
I settled down, curling into a fetal position with the biggest smile on my face.
"Get up, we've gotta go," Rita ordered, nudging me with her feet. I climbed to my feet, slowly, and followed Rita outside. "You get in the back." I climbed into the backseat and did all I could to stay awake. I was drained.
At some point I made it home and got into my bed. My parents weren't around, I think they had a dinner date or something, so I didn't need to worry about fielding questions regarding my outfit.
I was lying in bed, about to slip away into the night, when I heard my cell phone buzzing. I picked it up and looked at the caller ID.
'My Mistress', it read.
"Hello?" I answered.
"Do you have a pen and paper?" It was Rita.
"Uh, yeah, I think so," I said as I grabbed a notebook and a pen from my nightstand.
"Good, because I imagine your retarded whore brain won't remember anything I say otherwise," she continued. "Tomorrow, at school, you'll wear the same thing you wore yesterday. Don't wash it. I hope it smells like cum, that'd be a plus. And no bra, no panties."
Well, fuck.
"Okay, but I just got in trouble with the Principal for wearing it today," I replied.
"I don't fucking care. Not my problem," she snipped back. "Aside from wardrobe, there are some other basic rules. First, if anyone asks to see your pussy or your tits, you show them. Second, if anyone asks you to fuck, you do it. Blow jobs, butt sex, fisting, etc. You're basically a fleshlight that someone built a person around. And the last thing, and this is important, if you significantly disobey me or break those rules, I will punish you. And I'm good at punishing people. So think about how good I would be punishing a dog." She hung up.
I don't know what the fuck I'm going to do about the principal.
---------------------
The next morning, I woke up and showered before putting on my uniform from the day before. I looked in the mirror and, while it wasn't see through, there was no mistaking my tits. A cold breeze and I'd being poking through. The skirt seemed to cover enough of pussy that I'd just have to careful not to bend over too often.
The thing about this arrangement is that I want it and don't want it simultaneously. It'd be great to be a normal girl, but I also have this insatiable craving to be dominated and humiliated.
I left the house quickly to catch a bus. I waited at the stop in the cold weather with no jacket. I couldn't decide if Rita would be upset if I had one, but I figured it was best not to test her. So I waited in the cold.
The bus pulled up and, right away, I could see all the other students looking over me. I climbed aboard and walked down the aisle to find a seat. I could feel the boys pore over my body with lust, and several girls shot my ugly looks. A few envious glances.
I found a seat in the back. A couple of burn-outs sat in front of me. The bus rolled forward, merging back into traffic.
"Hey, forgot to put something on before you left the house?" One of the kids in front of me, I think his name was Scotty, had turned around to face me, looking down at me. Not particularly attractive, but was in good shape. His friend turned around shortly after him. Not sure of his name. Ronald? A rotund kid that wheezed when he was out of breath, smelled funny, and had been mostly a loner until he started smoking pot last summer.
"What do you mean?" I was playing coy, seeing where it went.
