"Oh my god, Nick, what is that?" I heard Marlo's voice say as I startled awake. I could feel my blind step-sister's hand on my morning wood through my pajamas.
I struggled out of sleep and up in the bed, and then brusquely brushed Marlo's left hand off from where it was resting, on my very hard six and a half-inch cock.
"Fuck!" I cried, "What the hell are you doing!"
"You overslept. I was just trying to wake you up to tell you that breakfast is ready."
My sister Marlo is a 19-year old brunette with medium-length hair who is sensitive about her looks, although I think she's beautiful in her own goofy way. Her front teeth stick out a bit, because she refused to get braces, and her blind brown eyes look, well, blind. But she has a nice and rather curvy figure, and she's definitely cute. And at 5 feet 9 inches she's kind of tall, although thank goodness I'm an inch taller.
Anyway, she was sitting on the edge of my bed, herself still in her flannel nightie that revealed some of the shape of her medium breasts with their nipples poking the fabric. She's been blind from birth, and had been adopted by my parents when they didn't think they could have kids—and then the next year I was born.
"Was I touching your penis?" Marlo said, and then covered her mouth in a pantomime of surprise.
Her performance would not have won an Academy Award.
I'm sure she knew she was touching my cock, and since I was really soundly asleep she might have had her hand on my erection for maybe a minute or more before I woke up. But you need to be careful about teasing a blind girl, and possibly she had accidentally— without being able to see what she was doing—put her hand on my crotch, and then she was maybe too shocked by my erection to move her hand away? Didn't seem entirely likely.
Anyway, Marlo couldn't see me blush, and actually this wasn't the first time she'd touched me there. When we play-wrestled she'd sometimes win by at key moments putting one of her hands on semi-erect cock saying, "What's this?" And I'd get distracted and let her go and say, "Stop that!" as she still clutched my hardening penis—and then she would pin me. But I think this was the first time she'd touched my cock when I was completely hard.
"No!" I said with a sigh, "You pervert. You were touching my pajamas."
"But what was that hard, warm thing under your pajamas?" Marlo said, and laughed.
"Uh...It's just a toy I sleep with," I said grimly, in what was an obvious lie, but which I hoped would put her off since clearly we were already on dangerous ground, just one day after our parents had left on their two-week trip to Europe.
But Marlo was clearly in a mood for some reason to push it, and to my amazement she said with mock innocence, "Oh, can I play with your toy?"
And then she started reaching back to my still hard morning erection.
"No!" I said in shock, and swatted her hand away again. What had gotten into her? I finally realized that it was because Mom and Dad were gone. And suddenly there was part of me that wanted to call her bluff and let her touch me there if she wanted to, but having been swatted away twice she seemingly was ready to give up for the moment.
"Touchy, touchy," Marlo said, and then added in a matter-of-fact way, "Anyway, breakfast is ready. Come on out and eat it before it gets cold. I made eggs."
I wondered if maybe I had I been blowing things out of proportion, and imagining things, in my sleep-addled mind.
"Okay. Thanks sis," I said, a little confused, "I'll be there in a minute."
With that Marlo got up and expertly guided herself without the use of a cane out of my bedroom and back to the dining room. We kept the house clean so she wouldn't trip, and she only needed to use a cane when walking outside.
Often I jerked off first thing in the morning, but locking myself in the bathroom for that didn't seem like a good idea at the moment (that would take a little while, and her sense of hearing was good), so I just brushed my teeth, managed to pee once my stiffy had gone down, washed my hands, and then came out to the dining room.
Marlo cooking eggs was really a nice accomplishment. Of course blind people can cook, but it's not easy. We have a special stove and ingredients in special containers that help make this possible.
Anyway, I wanted to show Marlo that I appreciated her work, and also that I was not upset about the "erection touching episode," as I was already thinking of it, and so I said as I saw the nice breakfast of scrambled eggs cooked with white cheddar cheese and pepper like I like it, toast with butter, and grapefruit, "Wow, thanks Lo," which is a nick-name I sometimes use for her. And I added, "This looks and smells great!"
"Thanks! Nothing's too good for my little bro," Marlo said, and then with a mischievous buck-toothed smile she said, "Did you bring your bedtime toy with you to the table?"
"Ha ha!," I said, digging into the eggs, and now knowing for sure that I hadn't imagined things. And so I added, "Yeah, sort of, but it's a kind of toy that can change size, and it's smaller now."
We obviously never talked this way around our parents. And in fact we'd never gone this far before when alone together, although some weird moments had happened between us over the years about bodies, weird sort-of flirting, and stuff.
She kept up her teasing smile and tone of voice, and said, "Your toy was kind of big before. How big would you say it is—7 inches?"
I stopped mid-bite to open my mouth in surprise that she'd said that, but then chewed and swallowed and decided to play along with her on the thin ice.
"Actually, it's six and a half inches when it's big."
And in fact, as we were talking about my cock it started to get hard again, which was actually somewhat obvious as I looked down at the beginnings of a little tent in my pjs as I was sitting there—but, of course, she couldn't see that.
"Well," Marlo added in a joking tone of voice, "If you ever want to let me play with your six and a half inch toy, let me know."
"What?" I said, shocked again, and laughed. But then I made an effort to keep up with what she was doing, and aded, "Okay Lo," I said, "You'll be the first to know. But keep this in mind. You're not the only sibling who can sneak into the other's bedroom when they're asleep and..." I wasn't sure what to say next.
"And what?" Marlo said.
"And touch someone else's...toy," I said awkwardly and uncertainly—and suddenly felt like I'd gone too far and felt ashamed. What was I saying to my blind step-sister?
But she said, "Go ahead! Since Mom and Dad aren't here, I don't care. Come in my bedroom any time you want."
"But what if it's the middle of the night?" I asked, shocked again by what I was saying.
Now it was Marlo's turn to pause while eating. She looked a little surprised, but was clearly determined to appear bold.
I felt guilty in that I had the advantage that I could see her, and she couldn't see me. But as you've already guessed that actually wasn't much of an advantage.
