My younger sister and I hated each other growing up. She was a year younger than me and was always telling on me for anything that I did wrong, as well as blaming me for stuff when she got caught. We pretty much ignored one another when we hit our teen years, and I bided my time until I went to college or moved out. All of this changed when Dad suddenly left home. Mom found out that he had a side chick when she showed up, asking where he was so he could pay his child support. Needless to say, Mom lost her shit and burned all of his stuff in the fire pit in the backyard. Mom ended up having some breakdown, leaving my sister and I to fend for ourselves for everything.
I did nothing for my sister because of my disdain for her. I'd only do my laundry and cook meals for myself. I had been doing odd jobs since I was fourteen and could afford what I wanted. I had a TV in my room and was bootlegging cable from our neighbor. I spent all my time in my room when I wasn't working or at school. I had suspicions that my sister was watching my TV while I was out of the house. I decided to set a trap for her and catch her in the act. A fat lot of good that did. Mom just screamed at me for being selfish and said she could watch it since I wasn't, and if I had a problem with that, then I should hook the cable up in the living room. I yelled back, saying, "There was no way that I was going to do that."
"Fine! Maybe you should go live with your father if you're going to be selfish like him!" Mom said, slamming my door.
I screamed back through the door, "You'd have to find the piece of shit first!" Her words burned through me like a hot knife. I hated being compared to my father, and it solidified my desire to blow this place. I shut myself off from both of them. I was the first one out every morning and the last one home every night. I'd come in well past dark, knowing that Mom would be passed out again by the time I walked in. I'd stay up late watching TV alone in my room. This went on for months until one night when I came home with a pizza for myself. I went to my room, stripped down to my boxers, and ate pizza as I clicked through the channels. I was surprised when my sister tapped on my door. "Is that Sal's? Can I have a piece?" she asked, coming through the door.
Even though I was enraged that she'd had the audacity to ask, I knew she probably hadn't eaten since breakfast. I pointed to the large pizza at the foot of the bed. I didn't expect her to eat in my room, and I definitely didn't want to have to talk to her. She thanked me as she pulled up my desk chair, which put my teeth on edge. She scarfed down the piece of pizza and asked for a second one. I hung my head, saying, "Go ahead." I was going to throw away what I didn't eat anyway. She must have taken that as a sign that we were somehow good now. We weren't! We were far from good, but I knew there hadn't been real food in the house for a few days now. I felt bad, remembering that she was in the same boat as I was. The only exception was she'd be here for a bit longer. I was taken aback when she climbed on the bed next to me. I briefly saw her tits down the neck of her baggy T-shirt, climbing next to me. "What are we watching?" she asked.
My jaw locked, and I took a deep breath, letting it out slowly, desperately trying to keep my cool. I found an R-rated movie that I had watched the night before. It had a lot of nudity and sex scenes. I left the channel on for a few seconds as the girl on the screen was giving a gut a blow job. I turned channels thinking that my sister would go narc me out for watching smut. "Wait. Go back. Can we watch this one?"
"Really? This is what you want to watch? No way am I going to give you another chance to get me into trouble again. Why don't you take the rest of the pizza and get out!" I growled at her. "Just get the fuck out!"
"What the fuck did I do?" she had the gall to ask. "I was watching it before you got home and thought, maybe we could finish watching it. It's not like you haven't watched it before. I know you jerked off to it last night."
"Like I said. I don't want you to go squealing to Mom. The next thing you know, you'll be telling her that you caught me jacking off. Now get the fuck out," I said, pushing her to get off my bed.
"I'm not going to tell. Besides, I was doing it myself until I heard you come home," Beth said, lifting her shirt to show me that she wasn't wearing panties.
"Bullshit if you were fingering yourself on my bed?" I pointed to the door.
She slipped her finger into her fuck slit, saying, "Look. I'm still wet."
"Gross. You ate pizza with those fingers," I couldn't help but laugh.
"It's not that gross," she barked back at me. "People eat pussy all the time. It's the same as her sucking on that guy's cock."
My sister slumped back onto the bed next to me. "Please. We have to start getting along cuz right now, we're all each other has," she sounded apologetic.
I slid under a blanket, turned my attention to the TV, and waited for the next sex scene. I knew it was a hot scene that went on for about ten minutes. I bent my knee sliding my left foot towards my butt, hoping it would block her view if I got a hard-on. When the scene started, my sister put my pillow over my lap. She didn't fool me. I knew she had her fingers in her hole. Between watching the pillow move up and down on her lap and the movie, I was rock-hard. I was torn between wanting to watch the film or watching my sister finger her cunt. Even with my knee up, I could see the bulge of my cock under the blanket. I noticed that my sister was glancing over at me as well. The thought of jacking off in front of her raced through my mind. When the sex scene ramped up, my sister pushed the pillow aside and started to rub her clit rapidly. She would then plunge her fingers into her hole for a few strokes before going back to rubbing her clit. I was so mesmerized by watching her I hadn't noticed she pulled the blanket enough to expose the tip of my cock. She looked like a form with her legs spread, bending at her knees. Her toes clenched tight like little fists as she moaned, "Oh yeah, Mmm, God." When she came, Beth just had a toe-curling orgasm sitting right next to me.
