"Ew! What are you doing?! Get away from me!" my little sister screamed in disgust after I flung her down onto the floor and started to straddle her with my cock swaying around freely above her face. I knew she hated it. She had always made fun of me for my ... extra part. It had tormented me every time she'd done it, and now the thought of getting her back was making my cock harden fast. I couldn't help but grin as I easily overpowered her and pushed her wrists down against her carpeted floor.
"Get off of me, you freak! What are you, some sort of pervert?! I'm telling mom!" she threatened in vain. That made me laugh. Our parents had gone away on vacation and wouldn't be back for the next week. No one came to check up on us since we didn't have any nearby relatives, and our neighbors didn't even like us. I laughed, sliding my feet under her arms and putting my knees down on the carpet to hold down her shoulders. I scooted forward until my swelling sac was resting on her mouth and nose. She shrieked, clamping her mouth shut and closing her eyes tightly.
"Go ahead, Tasha. Try reaching your phone." I chuckled, mocking her as I settled my weight on her squirming body. With my curves and her thig frame, there wasn't much of a significant struggle, but I still liked the fact that she was trying to get away. I bit my lip, scooting forward again to try and cover her eyes with my sac but she screamed and dug her heels into the carpet to push herself back and away.
"Get off of me!" she shrieked, partially muffled. Her hands curled into fists and fought to get back up, which they actually did. My eyebrows rose in surprise as she began to try lifting my body up and off of her. I figured I ought to stop playing around. With some quick movements while she was mindlessly flailing around, I dug my thumbs into the corners of her mouth to force her mouth open and then sat up, pivoting my hips into a launching position. With a grunt, and a whining growl from Tasha, I thrust my hips forward, shoving the first six inches straight into my little sisters mouth, pushing it all the way to the back of her mouth and flattening her tongue down against the bottom of her jaw. I closed my eyes as an electrifying wave of pleasure swept over my spine, making my lips part in a lewd moan. Tasha's eyes popped open as her understanding of the situation took a turn for the worst. I bit my lip, looking down at her as her body began to jerk about β her hands coming up to claw and pull at my own. Her mouth stretched open as my cock's shaft began to slide further in, getting thicker in girth. She tried to scream a protest but ended up gagging on my head, which made me moan louder, and momentarily made my grip weaken from the pleasure shooting through my body. She used that moment to arch her back, trying to knock me forward. It succeeded in bending me forward, making me take my thumbs out of her mouth to push them against the carpet to regain my balance. She started wiggling under me, trying to scoot down to slide my cock back out of her mouth but I sat back on her collarbone. She bucked again, pushing me forward again and making me scowl. She pushed her hands up against my ass and tried knocking me over completely. I reached behind me and snatched one of her hands out from under me, making her one hand unable to stop be from sitting back down, shoving two more inches in in the process and making her gag again. I continued to fight for my control of dominance as my little sister fought to get my thickening cock out of her mouth. While holding down her wrist with one hand, I grabbed a handful of hair with my other hand, sliding my thighs apart and lowering myself down on her face while pulling her head up by her hair to shove another three inches in before tightening my thighs around her head. She gagged and coughed, her free hand clawing at my thighs and making them tingle. I smiled as I felt my tip poke past the opening of her throat and began to stretch it. She winced, realizing it as well and squeezed my forearm.
"Nnnghh!" she cried, shaking her head in a desperate attempt to stop my cock from getting any further down her throat. But it only made my body tingle and my lips moan. I tightened my grip on her hair, holding it by the base and making her whimper. Her throat and tongue constantly swallowed around my cock head with the threatening position it was it in.
"What's the matter, Tasha? Can't take it to the base? I guess you're not as much of a slut as I thought." I mocked, shaking her head around. She glared up at me as her cheeks began to burn. I began to work my hips into a slow thrust, popping my mushroom head into her throat, making her gag hard and thrash against me in what most likely a mixture of panic and disgust. But all I felt was pleasure and revenge. Sweet revenge. My thrusting got faster. Harder. Until my movements were but a blur, and all I could hear from my little sister was slurps and gags and squeals while she frantically held onto my wrists. I groaned periodically as I face fucked my little sister, my back arching each time her nose was close to making contact with my naval. Soon my ginger hair was shaken free from its messy bun with all the thrusting, and was skewed about my face, neck, and shoulders, sticking to them as my body began to work up a sweat. Tasha began to cough at the rough thrusting, her throat squeezing my girth with each convulsion and making me shudder.
Then I stopped mid-thrust to look down at her. And frankly, to catch my breath. I huffed, breathing heavily. I still held onto her dirty blonde hair, which was now a ravished mess in my hands. And still, after being ridden like an animal, she glared up at me, tears forming at the corners of her eyes. But I didn't care. In fact, I still wanted more. I wasn't going to stop until I was balls-deep, and she was milking me for every last drop of cum I was going to launch into her. Her nails started digging into my wrists again after I had been still for quite some time with my dick still comfortably placed in her throat. I smiled, licking my upper lip and gripping her head tighter, making her widen her eyes. Had she thought I was done, perhaps? Poor girl.
I swung my legs out from the sides of her head, leaning back on her collar bone as I crossed them behind her head. Grunting, and huffing, I began violently pushing my hips forward against her face, twisting and pivoting to get the remainder of my length down her protesting throat. She screamed, squinting her eyes in what was probably pain, desperately trying to get her hands to my face to claw at. Realizing she did not have the leeway, she switched to trying to pull my arms away.
"Mmmghhnnff!!"
I hissed and jerked my arms away from her, holding handfuls of her hair as if they were the reins to a wild animal, pulling her head roughly towards me and plunging my hips down onto her face. I snatched and grinded her face against my pelvis while leaning back for leverage as I held my breath with a bitten lip. Her eyes shut tight, sending the tears that were building streaming down her cheeks as her nose finally smashed against my crotch, anchoring me balls-deep inside her throat. Having gotten what I wanted, I hurriedly tightened my crossed legs behind her head to hold it in the position and fumbled to grab her wrists, pinning them to the carpeted floor. I let out my saved breath and smiled, throwing my head back and panting as if succeeding in squeezing into a pair of skinny jeans that was three sizes too small. My teeth scraped across my bottom lip in bliss as I felt the disturbed walls of her tight inexperienced throat close around my shaft and continuous convulse, trying to expel it. She cried what she could, what with my cock half way to her voice box, and balled her hands into fists, trying to pry them from the pressure I was applying. Sitting back up, I looked down at her strained pink face and couldn't help the smile that came over me. The sight before me was marvelous. My little sister had my cock balls-deep down her petite throat, her nose squished up against my crotch, my swelling sac on her chin, and was down between my legs in such a humiliating position. I was in heaven. Not only mentally, but physically. And what made it even better, was that I knew I was close to coming. The contractions in her throat were doing more than I ever could just face fucking her. She was so tight, and yet such an amazingly perfect fit. I groaned a moan, and rolled my neck around on my shoulders.
"Oh my fuck, what a cock sleeve." I moaned with a heaving chest. I guess that made her mad because her attempts at freeing her hands were awakened. They pushed up against mine and I realized something. She could still breathe. I could hear it. Every pained struggle of air whistling rapidly past her nostrils. I giggled in approval. As long as she could breathe, I could keep her like this longer. However long I pleased if I wished. The thought of it made me ecstatic. Having my little sister as my personal cock holster. And with my new toy, that was exactly what I was going to make her. Letting go of her hands, I let her claw at my sides while I reached over on her bedside table for the restraint I had picked up at romantic depot. Her clawing paused as she watched the device with both curiosity and terror. I dangled it over her menacingly.
"Do you know what this is, Tasha?" I asked playfully. "It's a cock holster." I said, opening the multiple buckles. I slide it around my back side and strapped the back to my ass by buckling around my waist. "Or should I say ... A cock holster holder." I chuckled, looking down at her. She must have started putting two and two together because she bucked her hips up to try to throw me off. But with my position with my legs crossed behind her head, I wasn't about to go anywhere. One by one, I fought her struggles and buckled in each of her wrists to each of my hips, securing them in place. All that was left now was her head, which I was holding with my legs. Her fists pulled and tugged at the buckles as she squealed and cried, staring up at me with what was now pure fear. Taking my sweet time, I took each end of the buckles and wrapped them around her head, careful not to disturb its position. And then with sudden aggression, I tugged the buckle tight. Tighter, and tighter I pulled until the rod had made its way to the last buckle. I then, all together, took my hands from her, and stretched out my previously crossed legs along the floor. There she was, helplessly bound to my log of a cock, tensed, gagging, struggling for air, humiliated, with only me to look at. And here I was, body relaxed, legs spread out, hands resting on my thighs, panting softly, having my cock massaged by my little sister's throat, with an orgasm that would fill her to the nostrils well on its way. This could have very well been the best day of my life.
