18+! Let's do this. Here's your first dominant chapter. Please enjoy my dirty mind...

   I did my best to hide my smirk as the scantily clad boy crawled into the room. Oh I wanted to fuck his cute little ass until he was a mess on the floor, but I wanted him to suffer first. He deserved it anyways.
   He stopped at my feet, staring down at his hands on his knees. He didn't say anything for a few minutes, and I waited. If he went five minutes without speaking, I might go easy on him. Well, easier. He stayed quiet as I watched the clock, and I could hear soft whimpers starting to slip past his lips.
   With just under a minute left, he finally spoke. "I-I'm s-s-sorry M-Mistress."
   I ignored him and continued staring until the five minutes had completely passed. I looked down at him and he whined softly, shrinking into himself. I lightly caressed his face and saw him relax, even purring quietly. And that's when I hit him. He fell to the side with a cry, staring up at me with tears in his eyes. His cheek was bright red from the impact, but he was smart enough to keep his hands down as I got closer. I fisted his hair and he gasped, closing his eyes in bliss. "That's another rule you've broken. Are you wanting me to lock you up again?"
   He whimpered softly, his beautiful baby blues shining with tears. "N-no M-M-Mistress please don't lock me up again please."
   I stood and he got back in position, shuddering. I loved when I could see him like this. Fearful of what I would do to him, but still desperately wanting to please. He was normally such a good slut that it was only on very rare occasions I got to see him like this. I stalked around him, keeping one hand in his hair. He panted softly at the touch and I had to bite my lip back to keep my groan in. He was in trouble. I have to look pissed, not aroused.
   I stepped away and he visibly sagged. "What did you do wrong?"
   I'd made sure to put an edge into my voice, and he shuddered in the most delightful way. "I-I t-touched y-your property without permission a-and came without permission M-Mistress."
   I stood in front of him, watching his eyes fall to my feet obediently. "And?"
   He hesitated for a second and then I saw his shoulders sag again. "I-i spoke without permission."
   My lips curled into a smirk. "Defeat looks so good on you." He lifted his head a little to look at me, but he didn't meet my eye. "Go wait in the Dungeon. If I find a single issue with your position then I'll be doubling your punishment."
   He gulped and nodded, crawling back out of the room. I watched him as he left, enjoying the view. He was wearing blue thigh highs with an orange skirt that did absolutely nothing to hide his cute, peach shaped butt. And no panties. Such a fucking slut.
   I waited a few minutes and then started heading after him. I made sure to keep my footsteps light, and when I got to the door I stopped. I placed my hand on the door and shoved it open as hard as I can. It slammed into the wall and I smirked, eyeing the cute little whore in the middle of the room.
   He had his head down obediently, with his butt resting on his heels and his hands in little balls in his lap. He'd put on his black collar with metal rings hanging off each side, which actually did make me feel a little better. It was his punishment collar, and seeing him in it just did things for me.
   "Somebody is trying to make up for being such a disobedient slut, aren't they?" I asked as I approached.
   He quivered a little with each footstep and kept his voice quiet when he answered. "Y-yes Mistress."
   I hummed and massaged his hair, checking his position for anything amiss. I found nothing and gave him a kiss on his cheek. "Since you're being so good and obedient, I'll be nice and not put that cute little cock into a cage baby. Does that sound nice?"
   He shuddered at my touch, soft gasps slipping through his pretty pink lips. "Y-yes Mistress. T-thank you M-Mistress."
   I moved away from him and picked up my favorite whip. "Lay yourself out flat, arms above your head." He quickly got into position, panting in desperation. He was such a good little slut. "You are going to count and thank me for each lash. If you mess up, we'll start at the beginning again, and I'll add ten more."
   He gulped and I saw him tense up. Perfect. I struck his shoulder first, enjoying the cry of pain. "O-one! Thank you M-Mistress!" Next was the opposite shoulder. "Two! T-thank you Mistress!" Then between the shoulders. "T-three! T-thank you M-M-Mistress!"
   I continued whipping him until I saw blood, and then I kept whipping him. He was a sobbing mess, barely able to squeeze each number out before another batch of sobs would take over. I hit him a final time, as hard as I could. "S-sixty! T-t-thank y-you M-M-Mistress!"
   I waited for him to settle down as I looked over my handiwork. His skin was split in a dozen places, and several were bleeding. The parts of his back that weren't bleeding were a dark purple or black. He wouldn't be sleeping on his back for a while.
   I massaged his hair and he sobbed louder, turning his head to look at me. He had tears running down his face, destroying the makeup he'd worked so hard on. "I-I'm s-so s-sorry M-Mistress."
   I lightly kissed his cheek again. "I know baby. But I have to make sure you learn your lesson. Okay?"
   He nodded and I sat him up on his heels again. I set the whip back in its place and moved over to my collection of rings and dildos. I picked up the tightest ring in the bunch, a sadistic smile spreading across my face when he whimpered in fear. "You didn't think I was gonna let you cum, did you?" His head fell as I slipped it on, enjoying the small gasp of pleasure he made.
   I stalked back over to the table and selected the largest dildo in the collection, a black one that was around fourteen inches long and three inches across. I also picked up a vibrating plug and stalked back to him. His eyes darted back and forth fearfully, until they settled on my feet. He sat up when I tapped his shoulder, and then moaned quietly as I pushed the plug in. I didn't even have to use any lube.
   I turned the vibration to the 'tease' setting and smirked as he started moaning softly. Time to shut that up. I attached the dildo to a harness and then held it up to his waiting lips. He opened his mouth obediently and I wasted no time, thrusting into his throat harshly. He gagged loudly, but didn't try and push me away. I held the back of his head and continued thrusting, enjoying the pitiful sounds coming from my slave's throat.
   "You belong down there. With your ass plugged and your throat full of cock. Maybe I should get you a real one to try out." His eyes widened and I continued, groaning quietly as the harness pushed into me. "Real ones are so hot, and being filled with someone's cum is exactly the kind of thing you'd enjoy."
   He whimpered and I groaned again, the harness feeling amazing against me. I came, shuddering a little. He whimpered softly as I pulled out, dropping his head. I gripped his hair and yanked back, forcing him to look at me. "What do you say?"
   "T-thank you f-for using m-my throat M-Mistress."
   I chuckled and playfully slapped him. "Good boy." I released his hair and forced him to bend over, sticking his beautiful butt into the air. I pulled the plug out and he whined softly. I spread his cheeks a little and pushed into him in a single motion, pulling a gut-wrenching cry past his lips. "Aww, is it too big?" I mocked, enjoying his cries.
   I roughly pounded him, giving him no chance to catch his breath. There was so much power involved in this that it drove me crazy, and I knew he'd be sore for days after this. I always let loose, and he always suffered. If he didn't like the arrangement, he'd never told me so. Stupid slut.
   I pounded into him until his cries turned to moans and I laughed. "You love this so much, don't you? Being used and abused without ever getting to cum?"
   He nodded, throwing his head back in a long, drawn out moan. "Y-yes Mistress!"
   I laughed again and sped up, making him scream. "Dirty fucking whore. I'm glad you like it so much, because from now on you're going to keep a plug in at all times. If I'm not fucking you senseless, then it will. You'll never sit still again you stupid bitch."
   He moaned again and I smirked. My words probably weren't registering with him, but he'd still be getting the 'reward' I'd just told him. I checked my watch as I pounded him. After twenty minutes, he'd started to quiet down. After thirty he was begging and pleading for me to let him cum. Forty and he'd given up, accepting the brutal fucking without complaint. By the time an hour had passed, he was a drooling mess on the floor, unable to form coherent thoughts.
   I slowly came to a stop, pulling out of him. His breath hitched a bit, but there was no other reaction. I pushed the plug back into him and moved in front of him again, removing the harness. I pulled his head up by his hair and he looked at me, his eyes half closed in ecstasy. "Use your cute little mouth to pleasure me." He didn't respond and I chuckled, lightly smacking his face again. "Anyone home in there?"
   He nodded a little and pressed his face against my thigh. "Mistress..."
   I chuckled again and moved his face up some. "Me first baby. Then I'll let you cum. Okay?"
   He nodded again and started licking obediently, making me roll my head back in pleasure. He moved his tongue like an expert, and in minutes I was a moaning mess, gripping the back of his head in pleasure. "F-fuck baby, just like that." He sped up and I cried out, bucking my hips against his face. "C-cumming!" I screamed and coated his mouth and face, shuddering in pleasure.
   His eyes were barely open and I caressed his face, smiling. "G-good?"
   I kissed him, massaging his hair again. "Yes baby. So good. Don't you like being my good boy?" He nodded and I positioned him on his butt. "And now for your reward." I positioned myself above his swollen member and carefully removed the ring, earning a soft groan. I slowly lowered myself onto him, biting my lip as he scraped my insides. He wasn't very big, but the only thing I ever allowed inside me was his tongue, so it always felt just right when I did let him do this. He moaned softly and I turned the plug up some, making him start slowly bucking his hips up.
   I wrapped his arms around my waist and he squeezed as tight as he could, thrusting as I bounced. He was an absolute mess, and I loved it. "Such a good boy." I whispered into his ear, moaning softly.
   He moaned in response, laying his head against my chest. "Mistress Mistress please Mistress please." He couldn't even string together a complete sentence.
   I started bouncing faster, turning the plug on max. He screamed in pleasure and started bucking his hips harder. I moaned and gripped his hair again, the both of us shaking in pleasure. "C-cum baby!"
   We both screamed as we climaxed, him doing his best to thrust until I was finished. As we both came down, I chuckled into his hair. "That's a good baby. I love you." He didn't respond, so I pulled back some, gently lifting his chin. "Oh." He was out like a light, and I giggled. "Oops. Oh well." Maybe I should have gone easier on him. He'll live. I pulled his face back to my chest and sighed, relaxing. Might as well take a nap too. I was too sore to move, and I knew without a doubt he was. "Such a good boy."
