I woke up the next day almost forgetting what I had just done. Judging by my raging erection and carnal dreams, you'd think I hadn't gotten off in weeks. Still, my mind immediately jumped back to the night before and taking advantage of my blacked out sister.
I bounded down the staircase for breakfast, to find my parents sitting quietly. My Dad was reading the newspaper like he always did, but there was a palpable tension surrounding the table. "Oh God," I felt a flash of panic, "what if they know?!"
"Could you pass the milk, dear?" My mother got no response from my father, and was forced to awkwardly lean across the table to grab it herself. Without a word, Dad folded up his newspaper and pushed himself away from the table. The silverware clattered as he stomped out of the kitchen. "If you're not going to eat with us, will you at least wake up Becca?"
Becca. I realized she was probably still lying naked, covered in a pool of cum. My cum. Since the slut couldn't keep her clothes on, I'm sure Dad had woken her up in the buff before...but this could end up blowing up bigger than I intended. "Is everything alright?" Mom looked genuinely hurt, and I wasn't used to seeing them fight.
"It's fine honey," she smiled at the gesture. She had kind eyes and I saw more of her in me every day. Becca and my Dad had the temper and the muscles, but Mom and I had the brains and the heart. "Last night was...not as relaxing as we'd hoped."
"Ew," I blurted as I realized that Mom was talking about anniversary sex. I tried to block out thoughts of them humping, although my curiosity got the better of me. Could Dad not get it up? Maybe he finished early. Maybe he wanted Mom to do something she wouldn't. I tried to think about anything else when Dad came down without Becca.
"She's in the shower," he commented. I wasn't sure if I was relieved or upset that someone didn't catch her with a face full of cum. Mom shrugged and they went back to their awkward breakfast, which I was determined not to be a part of. I made an excuse about wanting to read in bed and left them alone, figuring they should hash out whatever happened or didn't happen last night.

I ate and read and even tried to sneak a peek at Becca in the shower, but couldn't get a good enough view. My room was a bit of a mess so I began to gather up plates and cups when I heard a car outside. I was bringing some laundry into the hallway when I heard familiar voices downstairs at the front door.
"Hi Mrs. Vinnet," Laura greeted warmly. She was a bitch, and knew just how to talk to parents so that they thought she was an angel.
"Well hello, Laura," Mom answered politely. "How's work going?"
"Great! I have off today so we're going to a museum. And Steph is back from school so she's coming too!" Stephanie was Laura's older sister, who I'd only met a couple times. She seemed nice enough -- way nicer than Becca and Laura -- but she never seemed to notice me.
"Becca's upstairs if you'd like."
The girls came up the stairs as Becca was leaving her room. She was wearing a tiny pair of bright red shorts and a mechanic's shirt that was half unbuttoned. It had the name "Rob" embroidered on it, but I'm sure nobody's eyes paid attention to the name so much as the tight wifebeater underneath that was stretching to cover her tits. "Why would she have some dude's name on her shirt," I wondered. It could be from some dude she blew, or maybe it was a fashion way, either way it was something I didn't fully understand.
Becca was putting on her earrings and didn't see me as she softly asked the girls, "Do I look good enough for a sex club?" Laura and Steph had eyes as big as saucers when they saw me behind Becca in the hallway, and Becca turned white as a ghost when she pivoted to find me standing there.
I backed up without even realizing it, Becca's imposing form bearing down on me with her two intimidating friends flanking her. "You didn't fucking hear that, ok?" I was more afraid than I'd like to admit...Becca's a girl and while I may be outright stronger than her, she was definitely bigger and meaner than me. And her cruelty probably reached depths that I couldn't even fathom.
"O...ok." I managed to eek out.
"If you tell anyone what I said, I'll tell them all about how I walked in on you playing with that little dick of yours." My face flushed red as I saw Laura burst out laughing. Steph tried to politely stifle a giggle, but bringing her hand to cover her face was proof enough. I was so mad, I wanted to defend myself and say that I wasn't playing with myself, or that it wasn't small. I wasn't really sure if both of those were lies, but it wouldn't help anyway.
"Oh my god, seriously?" Laura was almost snorting with derision. "Ugh it's so gross, I never even thought about it. I forget that little pissants like Dave have dicks."
"If you could even call it that!" Becca and Laura burst out laughing, and I saw Stephanie frown. The two were clearly enjoying this, but Stephanie was uncomfortable. Not uncomfortable enough to actually say anything, but it was some sort of solace in this personal hell of mine.
"Don't you guys have a museum to get to?"
Becca smiled and rolled her eyes. "Yes, little brother. Don't worry, we'll leave you so you can fuck your sock girlfriend or whatever."

I was beyond pissed. It was one thing to joke with Laura, who I'd dealt with since I was little. She'd blossomed early into a young woman, with small shapely breasts and short blonde hair that came down to her neck. I'd come to terms with having a second Becca looking down on me.
