Incest PERVERTED SIBLINGS

[neerathemall]

As I walked downstairs, I kept shaking my head. What the hell was that? What was the point of this - was she trying to pull some kind of sick joke? I planted myself on the couch and turned on the TV. For the next couple of hours, I was just going to watch something on there while checking my phone, getting my mind off that weird sister of mine.
I didn't get much peace, though. Not half an hour later, Callie showed up behind me. I didn't even notice that little ninja girl at first; she just snuck up behind the couch and stood there for... I don't know how long. All of a sudden, while I was in the middle of an episode of a Star Trek show, I felt her fingers stroking my hair.
"Ah!" I exclaimed, startled.
"Hey. It's just me."
"Don't sneak up like that!"
"Sorry. I just wanted to say it's okay."
"What?"
"It's okay, guys drool over me every day, you're no different."
She walked around the couch and came to sit in my lap, back to me. We used to do that a lot when we were kids. The couch we had back then was small, so we had to squeeze in to fit. Now we had a bigger couch, but we were both bigger too, so the love seat couldn't fit both of us lying down comfortably unless we sat like this.
"You know... Callie, you shouldn't do stuff like that."
"Sorry if it seeing a girl naked bothered you. I didn't know you were a prude."
"Okay. First of all: where's mom and dad?"
"They went out for a bit."
"Mom!? Dad?!" I called out, but there was no answer.
"Told you. They went out."
"Okay. I just don't think you should talk like that, especially if mom and dad can hear you."
"Talk like what?"
"About stuff like that. About... getting naked in front of your brother."
She pushed back towards me.
"Why not? I'm just teasing you. Can't you handle a little teasing from a teenage girl?"
"Dude... You're my sister. You sh..."
"Did it make you hard?" she interrupted.
"What?"
"Seeing me naked. Did it get you hard?"
"I... what..."
I couldn't manage a reply. I was just shocked. It was like my brain had to stop and rewind so that I could find out if I had actually heard her right. Realizing that I had, I needed to work out how I felt about getting a question like that from her, and how I could possible respond. After several seconds, I heard her giggling and understood that she was messing with me again.
"Oh, come on, will you stop that?"
"Hee hee! I'm having fun!"
"Well, I'm not. It's... weird."
"You're weird."
"No, I'm the normal one in this relationship."
"If you say so."
"Happy birthday, sis." I said, hugging her from behind.
"Thank you."
She smiled and giggled, grabbing my forearms and returning my hug. I felt her kiss my cheek and I responded with a similar kiss on hers.
"Do you know what I want for my birthday?"
"A unicorn."
"Besides that."
"A trip to Hawaii."
"Something you can actually give me."
"Well, you'll just have to wait for the party tonight to see what you're getting."
We were quiet for a while, just watching the show. For a moment, it seemed like she had dropped her weird attempts at messing with me. Then, right out of the blue, she brought them back up.
"What do you think of my boobs?"
She put her hands on her chest and held them, as if weighing them in her hands.
"What do you mean, 'what do I think?'."
"Are they as big as the girls in college have...?"
"Look, they're fine. You'll find all sorts in college, didn't I tell you that? Big, small..."
"Can you touch them and see?"
"What?"
"Touch them. Check if they're..."
"No!"
"Why not?"
She looked back at me over her shoulder and looked genuinely disappointed. Sad, almost.
"For one thing, it's weird."
"Disagree."
"Then there's mom and dad. They could be home any minute."
"I told you, they went out."
"For how long?"
She shrugged.
"Grab my boobs, wimp!"
She took my hands and moved them up to her chest. Before I knew it, I was feeling up her breasts. I didn't do anything at first, I just felt them through the cloth of her top and realized that she wasn't wearing a bra underneath.
"Well?"
"Well, what?"
"Come on. Touch them. Tell me what you think."
She started to apply pressure on top of my hands, pushing them onto her chest. I could feel her breathing; her whole bosom rising and falling under my hands. Her breasts felt nice and firm. Holding them in my hands gave me a very nice tingling feeling in my stomach, but I didn't want to own up to that.
"Well, I can't really feel much through the fabric." I said as an excuse.
"Oh. Yes, of course. You're right."
Callie lowered my hands and I thought for a second that she was giving up. Then I felt her hands guide mine up underneath her top. Before I knew it, my palms were holding my sister's naked breasts.
"How about now?"
I started feeling them. Kneading them gently, stroking them. I wasn't even thinking, I just did it instinctively. They felt wonderful. Her skin was so soft. Her nipples felt like small bumps in the middle of my palms. They were just big enough for me to be able to lift them up a little bit, but not so big that they lost their firmness. By the time I woke up to the fact that I was caressing my sister's naked boobs, it was like I couldn't stop. My heart beat faster and I realized that I was getting excited from something that shouldn't excite me...
Callie let out a slight moan. Alerted, I stopped what I was doing.
"No, don't stop, please..."
I gently kept going, stroking and holding them in my hands. She started whispering to me.
"They're nice, aren't they...?"
"Yes, they're very nice and firm..."
"What about the size...?"
"Nice and medium... Just right for your body."
"You like them?"
"Yeah, they're perfect."
I was telling the truth. They felt perfect. I kept telling myself that I was being nice, reassuring an insecure teenage girl about her appearance, but that wasn't the full story. The fact was, all my male brain could think about at the moment was how amazing it was to feel the breasts of a beautiful girl.
"So... are you getting hard now, then...?" I heard her whispering at me, still teasing and messing with her older brother.
"You'd feel it against your butt if I got hard." I retorted.
"It's that big, huh?"
"It would go up against your back."
"Mhmmm..."
"Popping up just above your shoulder."
We both laughed. A potentially tense moment had turned into something fun, which felt relaxing.
"Wow, so it gets that big when it's hard, huh..."
"Enormous."
"And it's your sister who makes it that hard? Wow, getting an erection from your own sister. I knew you were perverted."
"And teasing your brother in order to give him an erection isn't?"
"Well, maybe you should go and do something about that. If touching some boobs is all it takes, maybe you should go and jerk off while you think your perverted thoughts about your sister's hot body."
"Maybe I need more than your boobs to get me off."
"Don't you dare. I have it on very good authority that my boobs are perfect."
There was a noise coming from the hall.
"We're home!"
