Teasing Sister Gets Dominated (Closed)

My eyes darkened at her dejected response. I had smelled weed on her a few times when she had come home from hanging out with her boyfriend.


“If I didn’t want to give you a choice, I’d just strap the gas-mask to your face,” I said with a sneer. I circled around behind her and whispered in her ear: “I bet you’d actually like that…” I had a modified gas mask that would recycle the air within when it was strapped on. It could be hooked up to a bong and a massive hit of marijuana smoke could be fed into it, resulting in repeated heavy doses of the potent sweet leaf.


Most people could only handle it for a minute or two before passing out, utterly stoned. I was curious as to how long she could last.


“Wanna try it out?” I asked her with a smirk, grabbing her ass while I reached up and pulled it down from its hiding spot. I knew I would have to find a new place to stash my goodies now, as Mandy couldn’t be trusted, but that was okay…
 
Oh boy...he didn't look happy from that.

“If I didn’t want to give you a choice, I’d just strap the gas-mask to your face,”
my brother said, circling around me like a vulture. I was worried, a shiver going down my spine the moment I felt his breath tickle my ear with “I bet you’d actually like that…” . Gas mask? What on earth was Tommy going on about?

“Wanna try it out?” he then said, his hand creeping up and...

"AH!" I yelped, feeling his hand grab one of my ass cheeks - right as he pulled out a gas mask and showed me it. I was so confused for a second, but I think I read about it. Some people were using stuff like that to take in lots of weed! I was curious but seeing that mask well...it made me worried!

"Uh...no thanks Tommy." I answered him, looking around and seeing his laptop on the counter. I remembered that he had the stuff stored in the cloud right? What if I snuck to his room whenever I get the chance and delete it?
 
“Maybe later then,” I smirked, giving her big fat butt another squeeze and leading her on out of my room. We headed down the stairs and through the kitchen, where I stopped to grab a six-pack of beer out of the fridge.


“Hot tub time,” I said, nodding towards the back door. I guided her outside and flipped on the ever-present Christmas lights that illuminated the hot tub area, and then hit the switch to get the water roiling. I set the beer down within reach.


“Oops. I forgot my swim trunks,” I said, as I peeled off my tee shirt, showing off my athletic, cut physique.
 
I yelped again when I felt his hand go to my ass, giving it another squeeze while he led me downstairs. On our way there, I couldn't help but think over how disgusting my brother was! We were siblings right?! How the hell was he thinking about me in this super perverted, messed up way?! Either way, I found myself being brought to the hot tub, with Tommy giving me a grin, placing the beer near the hot tub.

“Oops. I forgot my swim trunks,”

He peeled off his shirt, showing off his muscular, fit physique. I tried to look away, thinking that maybe he wanted some privacy? I don't know... Well, that's besides the point, without his swimming trunks we wouldn't be able to go in the hot tub so -

"So, do you want to go upstairs and get them?" I asked, then reminding myself that I could totally use this as an opportunity "Or I can get them!"

That is, if he even planned on going in with swimming trunks! But there was no way that my brother was that perverted, right?
 
“Just get in the hot tub, Mandy,” I told her, leering at her exposed body as my thumbs hooked in the waistband of my gym shorts, playing at pulling them down and exposing myself to her. I could see her eyes linger on my impressive bulge, and to be honest, I couldn’t wait to show her just how well-endowed I was below.


“Beer?” I asked, pulling one out for myself and opening it, taking a swig. The marijuana joint was tucked behind my ear, and I was more than ready to spark that up, too.


So I did. I lit it up, got it smoking, and took a big fat hit off it before offering it to her. “Come on, take a hit and then get in the tub.”
 
Well there went my chance to go upstairs...Instead of letting me go get them (and seeing if I could get in the computer) Tommy basically told me that he planned on going in without shorts! He taunted me, his hands playing with his swimming trunks, making me look and see...a HUGE bulge in his pants! Oh my god, I just wanted to cover my eyes. Although, I guess if I had to be completely honest right now, I was a bit amazed over how big it was. I don't know, it seemed bigger than my boyfriend's and -

Wait, this is probably the alcohol speaking. Speaking of which...

“Beer?”

I gladly took a swing from a bottle. But Tommy had more than alcohol in mind for right now; from behind his ear, he pulled out a blunt and said:

“Come on, take a hit and then get in the tub.”

I wasn't about to say no! I think I needed that. "Sure thing." I said, almost too obediently before I took the joint in his hand and took a big hit! I puffed out the smell, slowly dipping my feet into the hot tub and feeling the relaxing waves. It might have been nice too, if not for well you know...
 
I took the joint back from her and watched as she lowered herself into the hot tub, taking another hit myself as she did. Only once she was all the way in did I offer it back to her… and once she took it and was having another hit, that’s when I finally dropped my shorts and stood before her naked, my massive length of cockmeat hanging lewdly between my thighs before I stepped towards her to get into the water!


“What?” I asked, innocently enough, setting my shorts within reach next to the beer, wanting to make sure my phone was easily accessible. After all, we still needed to take that selfie…
 
I stood there, completely immobilized when I saw Tommy behind, taking off his boxers - his big cock right there in the open! I was shocked, completely speechless when I saw him and it in front of me! Did he really do that? Did he really take off his pants and boxers? Was he really coming in here naked?! I thought about that, wondering just how big it was when he snapped me back into reality by saying:

“What?”

"Oh...nothing." I said, dipping into the hot tub and taking another swing of beer...
 
I smirked as I saw her gaze lingering on my man-meat while I stepped into the hot tub and lowered myself under the water right next to her.


“Puff puff pass, sister sweet tits,” I said, eyeing the idly smoking blunt in her hand. “We’re gonna burn that down, and kill this six pack here, and then take that selfie you owe me.”


I smirked. “And don’t worry, we’ll take it again and again until I get just the right shot,” I said.
 
"Fine by me..." I said, ignoring another nickname he gave me when I took the blunt from his hand. I took in another puff, thinking about the entire situation and how crazy it was! I tried to ignore the fact that Tommy was next to me and you know...naked by taking another hit. And another. Well, let's say that I was pretty generous with it before handing it back to Tommy.

“And don’t worry, we’ll take it again and again until I get just the right shot,” he then added, bringing up the selfie as I rolled my eyes a bit. "Geez, how many shots are you planning on taking? A selfie is not a big deal!"
 
“Oh I wanna make sure I get just the right shot. You know, for the old spank bank,” I said, chuckling as I took one final hit off the blunt and snuffed out what little remained in a nearby ashtray.


I took another drink before setting the beer down, and then my hand went underwater and found the little waistband of her bikini bottoms. I started tugging her closer to me under the water.


“Finish that beer, let me get you another.”
 
“Oh I wanna make sure I get just the right shot. You know, for the old spank bank,”

"Ewww...you're so gross!"

I found myself taken by surprise, once again, when Tommy's fingers found their way to my bikini bottoms and began tugging on them to bring me closer. I didn't want to because hey, he was naked, but if I didn't move along there was a chance they would just get undone so I moved closer to him...

“Finish that beer, let me get you another.”

I eagerly went for another beer, scooting closer with an asscheek on Tommy's lap! I tried to drink away the thought that this was incest, drinking from that bottle as much as I could.
 
I chuckled to myself as she drained her beer, and as it was upended, I stood up, and reached across her to grab a beer, my monster dick hanging right in front of her face as I did!


I plucked a beer out of the six-pack and opened it for her, still standing in front of her.


“Here ya go,” I said, handing her the fresh beer.


“Ya know, I might be persuaded to delete that video if you wanted to show me just how well you suck dick!” I said, my hand going to the base of my cock and grasping my thick meat. I stroked it out in front of her face.


“But I bet you couldn’t even get your mouth all the way around it!”
 
"Oh my god, what the hell is wrong with you?!" I nearly yelled, with my brother moving in close while standing - a huge, massive cock poking right at my face. "This is incest, you know that right?!" I added, as if he didn't already know. I stared at it for a moment, wondering how much bigger it was than my boyfriend's and - well, let's say that I wanted to move those thoughts away from my head. But that's the funny thing about drugs and alcohol, they really mess your brain up.

“But I bet you couldn’t even get your mouth all the way around it!”

He said that and I scoffed.

But then in my drunk and high haze, I thought about it and thought to myself why not? It could help me and no one needed to know!

I needed to be careful though... so I said "Well, you're not going to record me are you?"
 
“Of course not!” I lied, knowing full well that I already had a hidden camera recording secretly out here, and that we were in a perfect position to get some stellar footage.


I stroked my cock out in front of her again, letting her watch it stiffen up before her. The damn thing was almost as thick as a soda can, and probably as long as my sister’s forearm!


“Why don’t you start by wrapping those titties around it,” I suggested...
 
I was admiring the thing, which was absolutely massive. I mean, I don't even know how it was possible get that THAT big -

“Why don’t you start by wrapping those titties around it,” he suggested, moving a bit closer to me. Again, please don't judge me too hard because I really was high at this point and I was REALLY curious over how this thing felt. So, I took my breasts (still in the bikini top! I didn't want Tommy to see me naked!) and squeezed his cock in between my tits, from underneath them both. I gasped, feeling the warmness in between both the humongous tits of mine.

 
I grunted in pleasure as I felt her huge soft titties wrap around my cock, and as she squeezed them together my big dick throbbed in pleasure. It was almost overwhelming at first! It was everything I could do to keep from grabbing her and humping her chest immediately.


Instead I let her jiggle her tits up and down around me, and I stood there and savored the ecstatic feelings that coursed through me. I grabbed my beer and took another drink, looking down at her with a perverted glare.


My cock grew stiffer and stiffer as well, until the bulbous head was rubbing firmly under her chin!
 
Is it wrong that somehow, the disgustingness of it made it somehow feel good?

I don't know how else to explain it; how great it felt to have a cock, Tommy's cock of all things, between my huge tits. I groaned at the warmth and the feeling of how it struggling to fit in the tight cleavage I had, my hands going to the side of my breasts and rubbing them together on the thing. I saw it grow even more, and I moved my head down until I could lick around the head of his cock!
 
“Oh fuck, Mandy…” I grunted as I felt her hot tongue glide over the head of my cock. I was immediately overcome with desire. My little game was working all too well. Her was my sexy, curvy big sister, willingly putting her tits and mouth on my cock, and it was only just the beginning.


My hands went to her head, my fingers running through her hair as I raised myself up, pulling my cock out from between her tits so she could have a good angle to start sucking on it. She had to open her mouth really wide to get it all inside. It was pretty lewd… and easily the hottest thing I had ever experienced!


“Suck it. You fucking whore sister, suck your brother’s cock!” The words just fell out of my mouth, but hearing them out loud made my cock shudder and spasm against her lips...
 
“Suck it. You fucking whore sister, suck your brother’s cock!”

Somehow, those sick words made me want to suck in more!

It was messed up - the idea that I was sucking on my brother's dick but that aspect of it made it so much fun! I found myself opening my mouth more, trying to suck in more it, fitting as much of the width of his fuckstick in my mouth. It was so big that I thought that I was going to choke for a second! Bringing it more and more in all the while I could hear my own slurping noises.

* SLURP SLURP SLUP *​

My tongue ran all over the head, while my hands began to press the sides of my breasts more against his cock, rubbing them together up and down.
 
“You really are a dirty girl,” I said. “I’m impressed.” I smirked as I took a step back, pulling my cock out of her mouth with a loud “plop” before grabbing my beer and sitting down across the hot tub from her, so I had a perfect view of her abundant, luscious curves.


I took a swig off my beer. There was a remote control for the stereo, and I turned it on so music filled out stoned ears.


“Dance for me.” It was a demand.
 
“Dance for me.”

That's all I could focus on, in my state of mind. I got up, water dripping all over my body as I began to shake my hips to the music playing. My heart pounding at my chest, I swayed my ass and hips, moving in closer towards Tommy. A gasp escaped my lips when I felt his cock brush against the undersides of my ass, but I kept going anyway.
 
I sat there and stroked my huge cock under the water as I watched my sister dance in front of me, the bikini threatening to burst at any moment, and when I felt her big butt brush across my cock under the water, I couldn’t help but grab her by her hips and pull her back onto my lap!


My cock was nestled right in the crack of her ass, bare against the tiny fabric covering her down there.


“Wiggle that fat ass on my dick, slut,” I growled in her ear...
 
“Wiggle that fat ass on my dick, slut,” he said, just as I was processing how I managed to fall onto his lap!

"Calm down Tommy..." I whimpered, hearing just how aggressive his tone was getting. I began to rub my ass against that massive shaft poking me, feeling it press against the crack of my ass, and my inner thigh. I tried to hold myself in place, my hands reaching for the edge of the pool all the while I "danced" on his lap.
 
There wasn’t going to be any holding back now. I took a final swig of my beer before setting it aside, and reached around her with both hands and got full, firm grips on each of her tits! I squeezed and mauled her majestic melons, even as my hips started to hump my cock up against her ass in time with her musical movements.


I was dry humping my own sister, under the water, and loving every second. My hands on her tits were relentless, quickly yanking the bikini top to either side, fully exposing her to my secret camera!


“Grab my cock and start jerking it,” I demanded...
