Dares are so much fun.
"Er, yeah, good point. Sometimes I forget you're my brother!" I laughed nervously and dashed off to my room. I locked my door and lay down on my bed, my heart beating fast. It wasn't weird that he looked at my tits - he's just a guy after all and he had done it before - but it was weird for me to react that way. And now he saw me act so weird after he looked. He probably felt so guilty! Ugh, it was this stupid horniness why I was acting so weird. I pushed the awkward incident out of my mind, undid my jeans and shoved my hand under my panties. I got myself off four times over the next hour. I felt a lot better.
I decided I should go say something to Jeff to make things less awkward. Not even to bring it up directly, but just to let him know we were cool. I changed into more comfy jeans and threw a huge baggy sweater over my tank top and walked down the hall to his room. His door was open, so I just walked in, but he wasn't there. What was there, however, was his computer open to one of my more racy Facebook profile pictures, and a ball of tissue on his desk. It took me a bit to connect the dots. I was even stupid enough to pick up the tissue and smell it. That's when I couldn't deny the fact that my brother had just jerked off thinking of me. I heard the bathroom door open and my stomach dropped. Jeff's room was at the end of the hall, there was no escape. Of course he was in the washroom! I didn't even try to hide. I couldn't. I was stunned to where I was standing. Although I did thankfully drop the cum tissue back on the desk.
Jeff was horrified. "Julie?!"
I could finally move. And I ran past him without saying a word.
I have no idea why, but that was the moment when I chose to get angry. I turned back around.
"So, what? You think it's okay to jerk off to your little sister? Huh?"
"I don't, I-"
"I, uh, uh, I-" I mocked, "Don't try to deny it, you pervert, just apologize."
"Look, I'm sorry, Julie."
"You're damn right, you are! I'm your eighteen-year-old sister, you dirty fuck," I said. It was weird. I was starting to enjoy yelling at him. The anger was actually leaving me as I got more mean. Jeff was always awkward, but he was always my big brother and so he usually got the last word. I kept going.
"So what, you do this all the time?"
"No, no, this was the first time, I promise."
"Why today, huh? I've seen you stare at my tits before, you perv."
"I don't know, stop it, Julie," he said.
"Is it because of my old bra, huh?" I ripped my sweater over my head and my tits came crashing out inside my tight tank top and even tighter bra. "Just because I told you that bras are hard to find for super busty skinny girls?"
Jeff said nothing and I realized that I had been walking closer and closer to him while yelling. He actually appeared to be shaking.
"That's it, isn't it? It was finally too much to keep thinking of your kid sister growing such huge tits so fast that you had to jerk off to pictures of them. What about now, Jeff? They're so close to your face right now. Are you getting a boner now?"
"Fuck you, Julie," he said.
I don't what it was. I don't know if it was my anger, my sexually frustrated day, or even the fact that I missed my chance to go bra shopping, but I went the extra step. I grabbed my big brother's crotch. He had just jerked off, so I did not expect him to actually be hard again. But he was hard. And he was big.
"Oh," I said.
Jeff pushed me away and ran into his room. He didn't lock his door, however. I gave it a minute or so and gently opened the door.
"Look, I'm sorry, Jeff. I shouldn't have reacted that way. This is just weird for me. You have to understand that."
He said nothing, so I walked toward his bed slowly. He was curled in a ball turned away from me. I sat down on the edge, and I could see him twitch. I was starting to feel really bad.
"I really shouldn't have yelled at you and teased you like that, but you get it, right?"
"I'm just really embarrassed."
"It-it's fine, Jeff. Plus, it's kinda a compliment in a weird, twisted way."
"Don't do that
