This fictional incest story involves a brother and his younger, recently turned-eighteen sister. It is a mutual act sparked by the sister's voyeuristic observation of a kitchen sex spat between their parents.

Introduction
What could go wrong with teenagers Andy and Andreanna being home alone? Nothing, Hank and Doris thought. It was a quiet and very safe neighborhood. They were mature teen adults -- yes, young adults, but responsible enough. It wasn't as though they had idle hands -- the devil's tools -- Mom left them a list with plenty of chores. It was long enough to occupy those hands as mom and dad were away at work. Both were eighteen now, so being home wasn't a legal concern -- they had been latchkey kids after school since they were fifteen and taking care of themselves while Doris and Hank, as teachers, wrapped up after-school tutoring sessions with less 'bright' children. Yes, young adults would be home alone every day until the university started in the fall, so that wouldn't be a big deal, right?

Awakening an Irish Twin
"Andy, Andy, hey sleepyhead, are you awake?" My energetic, early-to-rise sister was knee-bumping the edge of my mattress, jarring me out of my slumber at eight o'clock in the morning.
"No, Sissy. I'm still asleep, silly. Go away and leave me alone," I groaned and turned over, facing away from my tormentor. Heck, she knew I was dead to the world when she entered my bedroom unannounced. Ten-ish in the morning was the earliest I'd get up, unless it was a school day -- and yesterday, high school ended for the summer. I was set to sleep in like a bear. Okay, I know bears hibernate during the winter, but I had to get up for school in winter, so I planned to slumber late this summer.
"No. ... You're awake, Andy. Listen, I know you will want to hear this," Andreanna droned on, disregarding my attempt to ignore her and catch a few more winks.
My younger sister kept driving her knee into the mattress, rocking my bed until it developed a familiar, rhythmic bounce. The box springs began squeaking just as it does when I'm 'shaking hands with the milkman.'
"Leave me alone. I need my sleep," I groused, still half asleep.
Sissy's bouncing was getting more insistent. If she didn't stop soon, I would have to get up and take care of the situation rising beneath my sheets. Something had lit a fire in her overly imaginative mind, I figured. Her voice was agitated, more so than usual for an early morning. It seemed my barking at her wouldn't douse that flame, and playing possum now didn't end her quest to roust me out of bed. Once she latches onto something, she's like a pit bull with a bone. So I rolled over onto my back, resigned to get an earful of 'want to hear this,' -- whatever 'this' was.
"Wow," she gasped, as her voice choked and went silent.
Even with my eyes closed, I could sense her gaze. Sissy was fixated on my penile tumescence, a good six-inch tent pole rising from beneath my sheet. She caused that. This time it hadn't risen due to my nighttime dreams. It was the similarity between her knee-jerking of the mattress and the all-to-familiar milkman's handshake.
"Hey, I can't help it." I growled, "You started it by rocking the bed. Sissy, you know you're supposed to knock before you come in -- that's the rule."
It wasn't that she didn't know about tent poles, the milkman, or masturbation already. We had mutual respect for those situations, and barging into my room while I attended to those times wasn't proper etiquette.
"Yeah, but every day with the stick-of-wood thing? Doesn't it ever stay down?" she giggled.
"Hardly--at least you don't have this obvious pole problem to deal with," I whispered, rolling over to face her. My wood wasn't so prominent lying on my side. Still, it ached for attention, tender love, and a hardy handshake that would send my cream rocketing into the air with a groan of intense satisfaction. I couldn't give it those caresses with Sissy in my face, grinning from ear to ear, and delighted in her discovery.
'Yes, Andy, I don't have a pole to deal with, but the same urges are still buzzing around my little button. It sure would be nice to use your pole to provide some relief,'
Sissy thought, as she smiled at her Irish twin's awesome-looking tentpole.
Andreanna's bemused look seemed to enjoy my predicament. "Well, what has you jabbering like a blue jay so early in the morning?" I asked, looking at her standing there in her frilly nightie. I tried blinking to clear my vision.
The nightie's hem was barely in line with the top of her pink panties, and her tits held it out from her tummy. Those two firm mounds poking against the tight-fitting gown gave a hint of the pink-cherry nipples beneath. Andreanna's taste for nightwear was to put on as little as possible -- just enough to stop Dad from getting after her for being bare-assed, as he called it when he scolded her for coming downstairs like a...
Dad and Mom had more than a few discussions about his choice of terms and how Dad felt her attire might be too much of a tease for me. A former college debater, Mom easily trumped all of his chauvinistic arguments. I figured that out last year when I realized he would get a frozen shoulder for a few days if he did something to irk Mom. It drastically affected his early morning exercises. I could tell whenever that happened -- their mattress thumping and box springs squeaks would be quiet for a few days. Dad would get the message, and soon stopped getting after Andreanna's at-home attire. That was okay with me; I got to see how my dream girls from school would look undressed, mostly.
And as for Andreanna, she wasn't bothered one bit. I knew she wasn't wearing it to tease me. That's just the way it was between us. As same birth-year siblings, nine months apart, we bonded almost as twins do. We shared our thoughts about guy-girl things pretty openly. That's how I found out girls fingerfuck, nearly as much as guys jerk off. I felt better knowing that tidbit when girl-gawking down the halls, picking out a beauty to turn on my imagination for some untamed thoughts. Before that, I thought girls never had sexual thoughts, and my almost-always-on sexual fantasies meant something was wrong with me.
Ridiculous, I know, but hey, you learn as you go. And with Andreanna as my backstop, I could get answers about girls' feelings toward guys that no one else was willing to share. If she asked me questions, I reciprocated, as frankly as I could. It was an inexplicable bonding. We made that 'Irish twins' pact our little secret.
Sissy even shared my name, as I was born, Andrew -- Andy. She got named Andreanna because, at her birth, Mom said, "You two are destined to be joined at the hip."
"Hey, Andreanna! My eyes are up here. Stop gawking. You said I would want to know something. Thanks to you, I'm wide awake now, so .... What's up?"
