I stared in thinly veiled desire as Laurie strapped on the dildo to her hips and positioned it at the entrance to my dripping wet cunt. Oh my god, was I really about to get fucked by a woman for the first time? With a dildo three sizes too large? I gulped and mentally prepared myself for the torment to come. 

Of course, as Laurie kept reminding me, with two words I could make it all stop. I could simply say “I submit,” admit defeat, and be done. But there's now fucking way I was going to do that. No, I was determined to outlast her. To prove I had the superior will. That I belonged to no one. 

But on the other hand.... I also didn't use the safeword. Why? Why did I let this continue? I only wondered for a second before Laurie pressed the tip of her rubber cock into me. I gasped, feeling myself beginning to stretch wide to accommodate the huge dildo. 

“Uhnn...” I grimaced, determined to withstand her torture. Laurie just smiled that sadistic smile at me that told me she wasn't going to stop until she was done. Slowly, she pushed it further and further into me and I could feel it all the way deep inside me. I tried to thrash against her but the motions only deepened the sensations.

“Ahhh....” I failed to hold back another moan as the dildo finally reached the end of me. I was completely and utterly filled, but there was still room to spare on the huge rubber strap on. 

“Ohhh good girl, look at you. You've taken almost all of it. Let's fix that,” Laurie teased. She kept pressing! 

“N-no! I can't!” I cried out. I was sure she was going to hurt me with this! “It's too much!”

“Hush, you're almost there. Just another inch.”

“Ohhh!” I couldn't hold back any more and let out a loud sound, but it only made her go further. I could feel my cunt expanding for her, past the limit of what I thought was possible. Past the limit of pain, into a remarkable place where all that existed in the world was me, Laurie, and this fucking dildo. 

I snapped my eyes open when Laurie stopped. My pussy was on fire, completely maxed out and filled to the brim. I looked up at her with pleading eyes. To my surprise, she praised me again. 

“Look at that! I knew you could do it. You got the whole thing, Ava,” she cooed.

W-why did that feel good all of a sudden? I felt like... I felt like because she told me I could, then I did...

“Submit,” she smirked at me.

“Mmmm,” I moaned again. I felt myself stretching ever wider, so slowly acclimating. “...no...”

SLAP! 

Laurie backhanded me again, right across the cheek. The combination of the pressure inside me and the new sting of pain made me moan out again loudly. There was no hiding it now, everyone could plainly see I was not so secretly loving this. 

“Fucking bitch. I'm done playing,” Laurie slowly pulled halfway out of me and rammed the dildo back in deep. 

“Ahh!” I yelled. Taking it all slowly was one thing, but to actually get fucked by this monstrosity?! 

She was relentless! She fucked me so hard my head spun and I lost all control of myself. I was moaning and panting for breath, hardly even realizing it was me making all those noises. She suddenly stopped, and slapped both my tits with her sharp hands. 

“Ugh! Nnn...” I moaned again. Fuck, this combination of pain and pleasure, it was... Unlike anything I'd ever felt. 

“Submit!”

“Nnnn-” I moaned before shouting “no!”

Laurie growled at me in return and pulled the dildo out so fast it hurt! I was suddenly left gaping, painfully empty, without her inside of me. She hastily grabbed a big, metal buttplug and stuck it into my gaping cunt. 

“I'll fucking make you, cunt,” Laurie said as she used my own pussy juice to lube the plug. Was that going to be enough?! She didn't seem to care. 

I flinched and pulled against my bindings when I felt the ice cold tip of the aluminum plug press into my tight asshole. Oh god, she was really going to do it? I couldn't see how big it was, but I didn't think she'd start going easy on me now. 

She pushed the tip, then the wide bulb of the plug into my tight little ass. I tried to squirm away from her, but I still couldn't move an inch. I was completely stuck immobile, with no choice but to accept her torment. I felt the plug go deeper and deeper, until she paused at its widest point. Oh god, it was torture! I thought i'd reached my limit on how far I could go today, but she kept pushing.

I felt a small pop as the plug entered me completely. Just the bedazzled base was left sticking out of me. I let out a light moan as I felt my asshole filled up with the cold metal. I writhed beneath Laurie in a mix of pleasure and pain. My ass was so full, yet my pussy was painfully empty... She seemed to think I deserved this torment.  

“Mmm...” I moaned. 

Laurie leaned down over me and whispered in my ear: “submit.”

I shook my head. 

“Cunt!” Laurie slapped me again. My cheeks were bright red and stinging painfully, only adding to me twisted enjoyment of this torture. 

Never out of ideas, Laurie retrieved a (thank god) regular sized vibrator from the bag. She unceremoniously shoved it into my gaping, dripping wet cunt and moved forward to position herself to be sitting on my chest. Oh no. I could see where this was going. 

“This is your last fucking chance, bitch. Submit!” She pressed the tip of her dildo to my lips, still wet from my cunt. I shook my head again. 

She reached behind her and flicked on the vibrator lodged into my pussy. It immediately started vibrated so strongly i had to moan.

“Ohh!” 

But she did her classic trick, and shoved the huge dildo halfway into my mouth, cutting off my cry. The combination of the huge metal plug in my ass, the vibrator mercilessly working at my cunt, and being hardly able to breathe around her dildo face fucking me was... Indescribable. I felt completely used, owned, stretched. She had used every part of me, every orifice was jammed full of Laurie. I couldn't escape it. No amount of pulling away would do any good. There was no hope for escape except for one thing...

Laurie rocked her hips back and forth, fucking my face with her strap on, and I knew this was it. I felt my mind started to go hazy, my body start to go limp as I had finally come to terms with what was happening to me. I was getting fucked, completely and utterly dominated, by my friend Laurie, the dominatrix. It was obvious to me now... I was no match for her. 

She pulled out for just a second to let me gasp for air, then jammed the dildo back into my mouth with no warning. I gagged on it, tears streaming down my face as I choked. It felt like she was really going to kill me with this thing!

The vibrator hummed away in my cunt, bringing me closer and closer to an unwelcome orgasm. An orgasm that would herald my failure. An orgasm I craved, that I so desperately needed. 

“Mmmm!” I moaned around Laurie's fake cock. 

“Take it all, you fucking bitch!” Laurie shouted at me as I choked on her. My cheeks were now wet with tears from being utterly humiliated and owned. She shouted at me until I finally reached the crescendo of my painful pleasure 

Oh no! No no, I can't... I- I!

“Mmm!!!” I moaned around the dildo choking me, completely filling my throat, as a wave of the most incredible ecstacy I've ever felt washed over me. “mmmm!!!!”

Laurie just shoved herself deeper into my throat as I spasmed under her. My body was entirely independent of my mind, moving on its own as my mind finally went totally blank. 

My body jerked and seized as my brain shut off. There were no thoughts, no cares, no more denial or worry... Only Laurie. Only... Mistress. I don't really remember a lot of what happened next...

I felt Laurie pull herself out of my mouth as drool spits down my chin. I didn't care. The vibrator still buzzed inside of my cunt, pressing inside me against the metal plug. Laurie said at that moment, my eyes glazed over, I stopped resisting, and I just stared at her blankly, gasping for air. 

She leaned low over me again and ghosted her lips over mine. 

“Submit,” she whispered. The tenderness of her features, the brutality with which she fucked me... All of it made my head spin so much I didn't know which way was up. 

“Mmm...” I moaned incomprehensibly. 

“Submit...” She stroked my damp cheek. 

“I...” I looked lazily up at her with unfocused eyes. “I submit...”

The smile that crept over her face was unlike anything I'd ever seen. A mix of triumphant joy, sadistic pleasure ...of dominance. 

“Say it again. Louder,” she commanded. 

“I submit...” I said again, loud enough for everyone to hear. I'd lost. I admitted it. I was no match for Mistress's superior will. She won. She dominated me, controlled me, forced me to her will. Once I realized how amazing it could be, I regretted ever resisting in the first place. 

“Good girl,” she praised. I felt a strange thrill at the words. Like everything id just gone through was worth it because she thought I was good. Mistress said I was good. 

“And what else, little slut?”

I stared at her blankly before remembering what else she wanted me to say. 

“I... I’m not straight,” I relented. 

“No little goddess, you enjoyed this far too much for you to be straight. You liked it, you liked me. Admit it.”

“You're right, Mistress,” I nodded, defeated. 

Mistress pulled her strap on away from my face and switched the vibrator off. I laid there limpy as she disassembled pieces of her domination. She pulled the plug out of my ass with a wet pop, and I felt my body turn into a pile of jello. I didn't even realize she untied me before I was cradled in her warm embrace. I was disoriented and broken, but I felt inexplicably safe in her arms. 

“That's a good girl. That's a good sub, Ava. We're going to have so much fun together from now on...”
