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.

I became aware of my cock sticking out of my boxers when she reached out to grab it in her hand. The touch of her hands sent shivers down my spine. She lunged forward and had my cock in her mouth before I could push her away. Her tongue lapped on the head of my cock, licking my precum off. She moaned, Mmm, again as she sucked my cock deeper into her mouth, sucking as she took me deeper. Her tongue flittered back k and forth on my shaft as her head bobbed. "Mmm, you taste good," she said when she came up for air. "Should I stop, or do you want more?" she asked, taking my cock back into her warm mouth.

"Oh, God, Beth. That feels so good," I whimpered, using her name for the first time in years. All my disdain for her melted away with every stroke Beth took with her mouth on my rigid member. Beth pulled the blanket off of me and tossed her leg over my body, straddling me with her back to me. She grabbed my cock, rubbing its head against her dripping orifice and lowering her cunt onto my shaft. Fuck, Beth's cunt was extremely tight, making me wonder if she was still a virgin. If it weren't for her juices, she would have struggled to get my cock in. Beth pumped her twat on my cock, coating my cock with her fluids until she had me all the way in. The sex scene was coming to an end, but Beth kept fucking me with her tight little twat. She pulled her T-shirt over her head and started playing with her tits as she rode my cock. I wished that she was facing me so I could see them and play with them. Beth rose up on her knees and tweaked her cunt on my cock rapidly, almost making me lose my load. I pushed her off of my cock so that I wouldn't cum prematurely. I moved between her legs, forcing them apart, and drove my face into her pussy. I licked her juicy slit, lapping up her juices like a man dying of thirst. I dug my tongue into her as deep as I could, wriggling it around inside her slut hole.

At first, Beth grabbed my hair, trying to yank my face away from her snatch, but the moment my mouth made contact, she moaned in pleasure. I swirled my tongue on her clit, licking it as I slid a finger into her. Beth squirmed as I gave her a scolding, licking the folds of her outer lips, circling her clit, and then back through her folds. I looked up at her abdomen, watching her squeezing her nipples as I fucked her hole with my tongue. Her body tensed as an orgasm built inside her. I licked harder on her clit as she cried out in ecstasy, climaxing on my tongue. I could taste a gush of salty liquid as she humped her cunt into my mouth. Beth, again, grabbed my hair, pulling my face harder onto her muffin. "Ahh, Jeez-Us!" Beth screeched through her teeth. "Put your cock back in me. God, please stick it back in my cunt." I climbed on top of her, sliding my cock into her slippery slit, driving it inside her, making Beth gasped sharply as I bottomed out in her cunt. I sucked her nipples as I pumped my meat in and out of my sister's pussy. When I lifted my head, Beth took it in her hands, pulling my face to hers, kissing me hard on the lips. Her tongue probed my mouth, swirling, twisting, and tangling with mine. A flood of emotions washed through my mind. Anger, rage, remorse, and lust flooded my thoughts. Lust for my sister. I angrily slammed my cock into her, taking out my feelings on her vagina. Beth grunted with each thrust of my hips, groaning her way to another climax. I hooked my arms under Beth's knees, raising them as I hammered away at her hole. "Cum, you fucker. CUM!" Beth growled through clenched teeth.

I slammed my cock deep into her hole, grunting, "I'm cumming, Beth. I'm cumming!"

I ground my hips to hers as my cock unleashed a copious amount of cum into my sister's pussy. All the while, Beth humped her cunt to my cock. Beth pulled my face to hers, kissing me again, driving her tongue into my mouth. "I'm sorry that I've been such a bitch to you, Mike," she said when our lips parted. "All this time spent fighting since Dad left, and we could have been doing this." She kissed me again. I pulled my cock out of Beth's cunt, and leaned back onto my knees, watching Beth scoop my spunk out of her hole with her fingers and lick them clean. "Your cum tastes good. Maybe next time you'll cum in my mouth," she grinned. "Mmm, looks like we won't have to wait long." Beth pointed at my still-rigid cock.

"Yeah! Maybe you should cum in your sister's mouth next time you fuck her," Mom said, standing in the doorway with her arms crossed.

"Mom?" Beth said, scrambling to put on her shirt. "I thought you were asleep."

"I was laying in bed when I smelled Sal's. I was getting up to come get a slice when I heard you two start fuckin'." I started to say something when Mom cut in. "Relax. I don't care if you guys fuck. At least you're getting along."

Mom stared at my cock as she walked in to grab a piece of pizza, pointing at my shrinking manhood, saying, "Wake me up next time, and maybe you can cum in my mouth, too," she said as she left the room.
