Sibling Rivalry – Saturday by dudebrodude

It can be tough having an older sister. They feel like they rule the house just because they were born first, and you’re the one always in their way, and so they take it out on you, or me in this case. I had this growing up two-fold, they were twins, so it felt like they were synchronising their aggression towards me, all the time, I was their scapegoat. If they were ever bored, or frustrated, I was the one they took it out on. They would do things like have one of them hold me down while the other put makeup on my face against my will, while my parents barely cared at all having dealt with it for so long. I thought it was all over when they came of age to leave the house, but they stayed on living here, and the torment got worse as they reached maturity. Yeah, maturity, that’s a bit of a stretch.

None more so did the torture become greater than it did on this weekend. The last weekend in August, a time which had become familiar to us as the weekend which our parents went away for it to celebrate their anniversary. This time around for the first time we were deemed by them old enough to stay in the house on our own for the weekend. I thought in their absence my sisters would have had plans to do other things, and maybe they would leave me alone for a bit, and I could finally get some rest-bite from them?

I was naive to think such a thing. It turns out for a while they had been planning something else entirely, something which heavily involved, well, the use of me, shall we say. It turns out as they had reached maturity, they had become a lot more curious sexually too, as can be expected. Though they had had gentleman callers on occasion, sometimes both of them with the same guy, which also lead to them trying more things together.

This was something which our parents didn’t know, but I did, seeing as they’d told me anytime they did anything of that nature, as if they were bragging about their exploits, and threatened me into not to telling them. I had learned by now to listen to them when it came to threats, because they certainly had a knack for revenge. I was never sure quite what they got up to together, as they would never really mention specifics, but it was clear just from overhearing them sometimes that they had become more adventurous with it over time.

It was a warm saturday afternoon, where I was enjoying my moment of peace downstairs with the tele on, my sisters upstairs. I didn’t know what they were up to, and quite frankly didn’t care as long as they weren’t annoying me. The peace wasn’t to last, as Tara came crashing down the stairs, the older of which by five minutes, and slammed the door open. I knew from the smug look on her face, I was in for it.

“Hey little bro,” she said with an evangelic tone, “Can we borrow you quickly, we want to try something?”

“Try what?” I asked with worry, fully aware of the past where I’d been more willing to help my sisters, and had that go horribly wrong.

“Let’s just say, it’s an experiment.”

“No thank you,” I replied, knowing full well that would not be accepted, “Just leave alone, please.” I said in a naive hope that she would.

Tara walked over to me and sat down next to me, and moved up close and said, “Come on little bro, just do it for your big sisters.”

I shook my head nervously and pushed away from her to the edge of the couch. A look of anger came across her face, and she pounced on me, grabbing me by both of my arms. I struggled to get free, and even though I’m not the strongest built I was still surprised how she could overpower me seemingly with ease.

“Well I guess we’ll have to do it the hard way”, she said to me, as she stood up still clutching my arms in her grasp, and started pulling me towards the door.

“Let go of me, bitch,” I yelled at her in anger. I’d never used such language towards her, but I’d had enough of her and Tia’s (my other sister, her twin) constant torment of me throughout my life. “What are you doing?” I asked, still struggling against her surprising strength.

“Like I said, it’s just an experiment,” she replied vaguely, “You know, this would be a lot easier for you if you let us do it.” There wasn’t a chance I was going to submit to her will, and I started struggling more, before falling to the floor still in my sisters clutches. She began dragging me across the hard-wood floor in the hall by my arms, before she came to the stairs and pulled me up them one-by-one, me hitting my head on each one as I passed it.

We reached the top of the stairs and I had still failed to break free of her vice-like grip, and she dragged me across my back along the carpet into the room she shared with her sister. She put me on the floor in front of their beds, which strangely they had pushed together to make a double, and there on the bed was Tia awaiting our return. She was dressed in something I hadn’t seen her wear before, it sort of had a lingerie look to it, a sort of see-through white dress that barely covered over her arse, and her breasts almost popping out of them.

Even through my hatred of her, I had to admire just how attractive they both were, looking almost identical to each other. They were both around 5’7, three inches shorter than myself, they had just past shoulder-length straight blonde hair, and blue eyes I’m sure their lovers would get lost in. They both had a great figure too, I’d imagine size 8 dress size with both their bottoms and breasts notably sticking out to give them a sleek, curvy physique.

I had gotten lost in my own thoughts, not even noticing that Tara had changed so she was wearing just her skimpy bra and panties, while Tia pinned me down. With that, and just knowing them in general, I was starting to get an idea of what they were planning, though I didn’t want to believe it. I could see no possible way out of it, with the both of them together more than capable of overpowering, especially considering what Tara had managed to do by herself earlier.

No one would hear me if I chose to scream my way out of it either, seeing as there was no one at home and we were in a fairly rural area with no other residence within earshot, and even if I’d tried I’m sure they’d just gag me, and if I was going through this anyway I’d rather have my voice for it, even if my voiced discontent were to be completely ignored. I was stuck here to be used for whatever they wished whether I liked it or not.

Tia stopped pinning me to the ground and both girls stood above me looking down at me. Neither said a word, they just glanced at each other and bent down to pick me up, Tia grabbing my arms with Tara grabbing my legs. I flailed wildly but they maintained control comfortably, and moved me over the bed and dropped me onto it on my back. Before I could even attempt to get up and escape, Tia jumped on me and pinned me to the bed with her body, while Tara went round the bed and handcuffed my ankles and then my wrists to the makeshift bedposts at each corner.

It was now clear to me that when they said they wanted to ‘experiment’ with me, they meant it in a sexual way. It would be completely non-consensual as I wouldn’t have even considered it, especially with my sisters, but clearly neither of these factors seemed to bother them at all. In fact knowing them like I do, it would probably even spur them on. And even though I knew I wasn’t going to enjoy what was coming, my body was reacting to the pressure Tia was putting on me with her body, and she looked up at me with an evangelic grin, clearly noticing that I was poking her through my trousers.

“I think he knows what’s coming sis!” Tia said, sounding remarkably like her twin, looking over to her sister who had now climbed on the bed and knelt beside me to my left.

“Mm I don’t think he wants it, just look at his face, but I bet he’ll enjoy it. Won’t you?”
Tara said, directing the question towards me. Not sure if it was rhetorical or not, I shook my head in panic, mistakingly so as I received a quick slap on the cheek for my disobedience.

“Take that as a warning,” she scowled, “Because if you don’t answer us correctly, or address us correctly for that matter; as either mistress or sis, whichever you’re more comfortable with; we have plenty more ideas of how to punish you for your indiscretions. I could tell from the tone of her voice that she was serious, and that it would be in my best interest not to get on her bad side this time, especially considering the position of vulnerability I found myself in. “Are we clear?” she added.

“Yes, sis.” I responded in fear, to which she fiercely replied, “Good, you little bitch.”

Tia lifted herself off my body, now revealing the quite protruding tent I had going on beneath her. She then said to Tara, “Shall we begin then? Should we tell him what’s going on, or leave it as a surprise?” Two questions which left me in an even deeper state of worry, I thought this was the surprise, what more could there possibly be? A dangerous question I immediately wished I hadn’t thought of. Tara turned her attention towards me, and began to explain.

“Well you see little brother, as you well know me and Tia have been more adventurous in recent times, sexually. See, as we’ve been doing more things with each other, over time we’ve developed a sort of fantasy together, one which we’re too cautious to try on some random guy we can pick up. But then we thought, we could do it with you, because we know you wouldn’t dare to tell, would you? Because you know exactly what we’re capable of if you did.”

Tia continued on her behalf, “The point though, is we’ve been talking together recently about our fantasies, and one that we had in common was to completely dominate and humiliate a guy sexually, and you were the perfect candidate to perform our experiment on. We’ll ease you in though, as we know you haven’t had any sexual experience yet, so you can get used to the ropes, but after that you’ll be all ours, forced to do whatever we wish. Is that clear?”
