When my parents said they were going away for the weekend I knew that Tristan would take full advantage. However, nothing could have prepared me for his true intentions.
“I’m inviting Chris over to hang out and I want you to be my obedient little slut while he’s here,” Tristan said as if it was the most normal request ever. Of course, I knew that despite the friendly way he’d said it, it was not a request at all.
“You cannot be serious,” I said, crossing my arms and staring defiantly at my little brother.
“I am dead serious. I’ll tell you what, if you do everything you’re told and don’t refuse even once then a knock a month of your sentence. I’ll delete the evidence I stole from your computer in 5 months instead of 6. But you have to do everything I say no matter what,” he said.
“No way,” I said, shaking my head. Obeying his perverted instructions was one thing but letting his friend witness it was out of the question. Everybody would know about my humiliation by Monday.
“If you don’t then I’ll just have to tell Mom and Dad what you did,” he said with a simple shrug.
I was trapped, and Tristan knew it. I knew that he was going to make my life a living hell while Chris was over, and there wasn’t anything I could do about it. The least I could do was get a better deal out of it.
“Fine but. want 3 months taken off.”
“No way, big sis. 1 month and I won’t force you to admit that you love sucking my cock,” Tristan said with a sly smile.
My cheeks turned bright red and I felt my desire for him start to grow despite my regret and shame. I knew whatever pleasure I derived from it was only temporary, and that I would still regret my behavior once it was all over. But in that moment all I could think about was his big, thick cock and my hunger for it. It was without a doubt the best cock I’d ever had, and it no longer mattered that it was attached to my little brother. I shook the thought away, determined to get something out of this situation other than sexual release.
“3 months,” I said.
Tristan considered me for a moment before replying. “2 months and I’m choosing your outfit.”
I knew that he could force me to do everything he wanted for nothing so I agreed to the deal and took what he offered. He’d delete the evidence in only 4 months and I’d be free from his control. The deal seemed pretty good until he got back from town with a brand new outfit for me to wear.
Tristan had chosen me a purple crop top that was made out of material so sheer it was almost see-through, and a pair of black lace panties. No shorts, skirt, or anything to wear over the panties.
“Tristan I need shorts or something!” I protested.
“Nope. That’s your outfit. That’s the deal. You agreed. Get changed. I want you in the living room before Chris gets here.”
“This is not fair,” I said feebly, staring at the panties in my hand.
“Tough titty said the kitty,” he replied before strolling out of my room.
I got changed into the most revealing outfit I had ever seen and took a look at my reflection in the mirror. My nipples were clearly visible through the sheer material of the crop top and the lacy panties barely covered a thing. If I bent over the panties would disappear into my ass crack leaving my cheeks on full display. And Tristan would definitely make me bend over at some point tonight.
I already felt exposed and vulnerable, but it wasn’t just my outfit that made me feel that way. It was the knowledge that I was going to have to do whatever Tristan wanted in front of his friend. It was the knowledge that my brother was in control and that I had no power to stop this.
I could come clean to my parents and tell them I trashed their car, but that would mean they wouldn’t buy me my own car for Christmas. I’d be punished for the next year at least. No, I had to obey my brother. There was no choice.
I walked down to the living room in my horrible outfit and curled up on the sofa, trying my best to hide myself as much as possible. I considered hiding beneath a cushion but I knew Tristan would only take it off me.
Just then I heard a loud knock on the door, signaling that Chris was here. I knew that Tristan was going to take full advantage of this situation and I had no choice but to obey him. It was going to be a long night.
My brother led his friend into the room and Chris’ eyes nearly flew out of his head when he saw what I was dressed in.
“Oh… hey, Erin. I didn’t know you’d be, erm…” Chris trailed off, his eyes glued to my breasts.
“Hey, Chris,” I said wearily and fixed Tristan with an angry glare.
“Let’s put a film on,” Tristan said. “Erin, go you grab us a couple of Dad’s beers from the fridge.”
The first order of the night. Obviously, Tristan, being only 18, was not allowed to drink but I had agreed to follow his instructions without arguing. That was the deal. Besides, Tristan did a lot of things he wasn’t allowed to do these days. We both did.
I sighed heavily before standing up and dragging myself to the kitchen. I was aware of Chris’ eyes roaming all over my body as I left the room. I grabbed a beer for myself whilst I was in the kitchen. If I was going to have to endure a night of humiliation I wasn’t going to do it on a clear head.
I stepped back into the living room and gave my brother and his friend their beers before setting my own down on the coffee table.
“Right, let’s watch a movie,” Tristan said, pressing play.
I tried to pay attention to the film but out of the corner of my eye I could see Chris staring at me. He was still in disbelief that I was sitting so freely in my almost non-existent outfit.
We were about 20 minutes into the movie when Tristan gave me my next order. “Erin, you look hot. Take your top off and cool down.”
Chris’ eyes bulged and he looked at me with shocked excitement.
“Are you for real?” Chris asked.
“Oh, I’m for real. Erin tell Chris what a horny slut you are.”
My cheeks were glowing red with humiliation but I knew there was no way out of it. “I’m a horny slut,” I said through my teeth, burning with embarrassment.
Chris laughed and said, “Prove it then. Take your top off.”
I peeled the material of the crop top away from my body and revealed my bare breasts to the two of them. Despite feeling exposed and vulnerable, I couldn’t deny the strange thrill I felt showing my body to them.
Chris was red with arousal and couldn’t take his eyes off me, and although Tristan kept his composure, I could tell that my bare flesh was also affecting him.
“Woah, you really are a horny slut. Dude, what the hell is happening?” Chris asked Tristan, but he never took his eyes off me.
“Erin does whatever I want now. And she loves it. Don’t you, sis?” said Tristan.
Holding my tongue, I nodded once, and Tristan grinned broadly. “She’ll do whatever we want tonight.”
“Erin you look amazing,” Chris said, still staring dumbly at my breasts.
“That’s code for you’ve got nice tits,” Tristan said with a laugh.
I smiled awkwardly and fought the urge to cover myself up. I felt embarrassed and violated but I couldn’t deny the pleasure I felt being the object of their attention. As uncomfortable as I felt, this was also making me very aroused. I was conflicted by the mixture of desire, humiliation, and hunger for their cocks. What was happening to me?
“Come and sit between us,” Tristan said, patting the sofa between him and Chris.
I hesitated for just a second before obediently walking over and sitting between them. It was a tight squeeze and my legs were pressed against theirs. We resumed watching the film and Chris folded his arms across his chest. At first, I thought he was embarrassed and was folding his arms to keep them out of the way. I learned differently when I felt his fingers clumsily poking the side of my breast.
I gasped with surprise and my heart started to race. Chris gave me a weak smile and looked away, embarrassed that I had caught him.
“Go ahead,” Tristan said with a smirk.
Chris turned to look at him, still not entirely sure if Tristan was serious.
“It’s okay, I told you she does whatever I say,” Tristan said before turning to me. His voice softened as he turned to me and said, “It’s okay Erin. Let him touch you.”
I felt embarrassed, yet strangely aroused by Tristan’s words. I looked down, avoiding eye contact with the two of them, and felt Chris’ fingers make contact with my skin. He started to trace circles around my nipples before squeezing them experimentally. The awkward way he groped me made me think he’d never been with a girl before.
