For some reason, that made her laugh. “I think I’m pretty, but I’m nowhere near as beautiful as Karina is.”
“Bullshit. You’re extremely attractive,” I told her, probably a tad more emphatically than necessary.
“You’re just saying that to be nice,” she snapped back.
“Like hell I am. Do you know how often I had to hear your name in the locker rooms at school? You developed pretty early on, and everyone noticed. And I promise that attention didn’t wear off as you got older.”
“Really? You never told me that.” She sounded genuinely surprised.
“Would you have wanted me to tell you that? All I would have heard from you is ‘Geez Trev, stay out of my business,’ or something close to that.”
“Yeah, you’re probably right,” she agreed reluctantly. “Still, it feels good sometimes being told you’re pretty.”
“Come on, Carly. I’m sure you hear that from guys all the time,” I rationalized. Surely, she did.
“Not really,” she moped.
“I bet you do. Maybe you just don’t always pay attention to it,” I said, certain I was right.
“You think so?” Her voice perked up a bit.
“Sure. But I think it also matters who is telling you. You don’t want a creepy old guy to tell you you’re cute or sexy.” She shrugged at the thought. “Or your dorky brother.”
“Yeah, doesn’t have the same effect,” she agreed with a bit of a smile.
“As well it shouldn’t,” I said with a nod.
She stared at the wall for a few minutes. “Trevor, do you really think I’m sexy?”
“Well, yeah, you are,” I confessed, and I wasn’t lying.
“So, does that mean you get turned on by me?” she asked, her voice genuinely curious this time.
I took my time, answering carefully. “It means the possibility exists, even if it isn’t true at the moment.” I couldn’t bring myself to tell her I was turned on, even now.
“Oh.” She seemed disappointed.
“Look Carly, it’s not like I get an instant hard on when I’m around you. But I can see and acknowledge that you’re an attractive woman.”
“And you’ve seen me naked now,” she added.
“That was an accident. And not my fault either,” I pointed out.
“So, what did you think?” she asked innocently, looking down her shirt at her breasts.
“It … confirmed my suspicions.” I chose my words carefully again.
“Come on Trev, please. Just tell me what you thought about me when you saw.”
I was stuck. So, I took a deep breath and just told her everything. “You have really nice tits. They’re big and full and looked really firm for their size.”
“Go on, please,” she said, one hand clutching the neckline of her shirt tightly.
“The rest of you was just as nice. Your body is nice, you’ve got that all-over tan and a cute, round butt. And I noticed you didn’t have any hair … down there.”
“My pussy?” she said, cupping it with her hand over her shorts. “Rick talked me into waxing it right before we broke up. Did you like it?”
“It looks really good on you,” I assured her. “But I promise, I wasn’t trying to look or perv at you. I got like a fast glimpse, then you were out of there.”
“I know. It wasn’t your fault.” She looked around, squirming in place a bit. “So … do you have a hard on right now?”
“Kind of.” That was mostly true. My dick was not fully hard, but nowhere near flaccid either. “Maybe 7 out of 10?”
“Oh,” she said softly.
“Why?” I had to ask.
“Well … I’m kind of turned on right now talking about all this with you,” she whispered.
“Umm … I’m sorry?” I had no idea how to respond.
She cupped her breasts in her hands and squeezed them lightly. “Yeah, I’m going to my room now.”
“Yeah. Have fun.” I earned the remaining points immediately.
“I know I will. You too.” She grinned at me knowingly.
She was right, as soon as she left, I whipped my thickening cock out and began to pump it rapidly. Seeing her feeling up her tits right in front of me, wow. I knew she had nice ones, even before I saw them the other day. And then the awkward-but-hot unreal reality of telling my sister what I thought about her body. It was definitely getting me aroused. It had obviously had a pronounced effect on her too.
And then I thought about what she was doing. She had gone into her room to masturbate; I was sure of it. My mind started picturing things. Was she leaning back against the headboard, legs spread, knees up, running her fingers up and down her wet slit? Or was she using two fingers and finger-fucking herself with them? Did she use a vibrator on her clit? Then, the last question crossed my mind, did she and Karina ever use sex toys on each other?
And like a shot, I was cumming again. Wave after wave of cum landed on my belly. Well, that shirt was definitely going to be stained now. I groaned as the last drops flowed out of my cock. I felt a bit of shame, jerking off thinking about my sister. I pulled off my shirt and pants and, with my boxers at my knees, waddled over to the bathroom door. I wanted to grab a towel or something to clean up with. I knocked on the door twice and, hearing nothing, went in and went to the sink to rinse my hands off and wet down a washcloth.
And of course, Carly chooses that exact moment to open her door to the bathroom as well. I didn’t fully notice at first, but she had taken her shorts off and was standing there staring at me in just her shirt and panties. My sister looked over at me, her eyes bugging out. We both froze in place for a moment, then she burst out laughing. I spun around and tried to pull my boxers up over my ass with one hand. Why I didn’t think to drop the wet washcloth in my other hand I’ll never know, but I struggled to pull them up one handed.
“You need some help there Trevor?” She laughed some more.
“Go away. Aren’t you supposed to knock first?” I replied angrily, still holding my boxers up with one hand
“I was just going to wash my hands. But you go ahead, you’ve got much more to clean up than I do.” She giggled and left the bathroom.
I stood there, thoroughly embarrassed. I wiped the wet spots where cum had soaked into my shirt off my stomach and cleaned the dribbles out of my pubes. Gingerly I wiped off my sensitive, softened dick. I washed the rest of my jizz off my hands and pulled my boxers back up. Why did she have to wash her hands at that exact moment? What was so important that it couldn’t wait … Ooh. The realization hit me. Her hands were all wet and sticky from touching herself too. Her shorts were gone. She had probably gotten off and now had wet, sticky panties wedged up against her cunt lips. That thought made my head spin. I went back to my room and put my shorts back on. I needed a new shirt now.
