1 AM? “Why do I always do this?” I think to myself. Sitting in a dark room my face illuminated by the screen. I click to search for the next game. It should come as no surprise.  Anytime my wife is on a business trip I stay up late gaming. It’s a wonder how such a beauty ended up with such a nerd. Slumping back into my chair, the crisp crackle of a coke can only add to the silence hanging in the room. As much as I love her I do love my alone time just as much. As I dial in to prepare for my next match a sudden knock at the door startles me. “it’s 1 AM, who the fuck could this be?” I whisper annoyed. Slowly unbolting the locks, I take a moment to mentally prepare for this unnecessary disturbance. I slowly open the door “Steph? What are you doing here? Is everything ok?” I ask concerned. My previous feelings disperse and are quickly replaced by confusion and a moment of shock. “Why would my sister in law show up at such a time?” I wonder, observing her. A stylish sleeveless black dress hugs her petite figure elegantly accentuating her breasts. They couldn’t be much larger than a C cup, but at 5 feet tall and a tiny waist they looked immense. I always did find her to be a beautiful woman, all the women in her family have an air of elegance and grace about them. An aura of royalty even. It quickly dawned on me she has had a few drinks, as I know all too well from experience all it takes is a couple to get the sisters drunk. Steph stumbles forward with a bubbly giggle, ” Big Brother! I missed you!” she exclaimed, as she flung her arms around me. Her soft breasts pressing against my chest. Big brother, she truly did see me like a brother and I loved how cute it was.  I wrap my arms around her giving her a tight hug. ” I missed you too Steph. is everything ok?” I ask again. “Oh it’s fine big brother, I was just out on a date and a guy soooo hot! . Ugh but he was such a tool. I’m tired of these fuckboys. I want a good guy who treats me like you treat my sister. ” she loved going on dates, she wasn’t a promiscuous girl, but she certainly knows she’s attractive, and loves the attention. “You’ll find him, you’re a beautiful girl don’t doubt it for a second.” I say, still confused why she came here instead of her mother’s house where she lives. If I had to guess she didn’t want to go home this drunk, her mother hates seeing her daughters drunk. “Oh, I know big brother, is it ok if I stay here tonight? I know Izzy is out of town and I didn’t want to go home drunk. I’ll keep you company so you won’t be lonely!” she slurred. “Fuck, there goes any chance of me continuing to play tonight” I think to myself. “Of course Steph! Anytime, you know that. Come in let me help you.” I softly take her arm in my hand and lead her inside. She slumps down into a chair as I fill her a cup of water. “God why did he have to be such a tool, it’s been so long since I’ve had any dick because of this virus.” a look of embarrassment overcame her. She isn’t one to so openly talk about sex so I’m quite surprised. I hand her the cup of water and kneel down to help her take her shoes off. She lifts her leg up to my eye level, and I carefully slip off her heels. Her feet are so tiny, she could probably buy her sneakers from the children’s section. I had never noticed how pretty her feet are. I suppress these thoughts. “She’s my younger sister, she’s in need of my help, do not sexualize her especially when she’s in this state.” I think to myself. “God I really need to shower, I feel so gross!” She states as she gets up from the chair. “could you help me with my dress? the zipper is impossible. You are such a good big brother you always take such good care of me.” I approach her from behind and get close to her. She smells intoxicating. As I unzip her dress it slowly peels away from her soft skin and falls to the floor revealing her naked form. “My god, her ass looks incredible. What a bubble butt.” I think to myself. I feel my pants grow a little tighter as I try to  again suppress these thoughts. “Shit I’m so sorry, I didn’t know!” I nervously sputter out trying to shield my eyes. “It’s ok big brother, I don’t mind I trust you.” she turned facing me taking my hand slightly struggling to stand on her own. ” big brother can you help me get in the shower?” I look at her slightly wide eyed. “s… sure.” taking my hand leading me to the shower. She stepped in and laid down” do you mind if I lay down?” I take the detachable shower head and test the water temperature. Steaming hot. I look down at her laying down, her legs bent knees up looking me in the eyes and I begin running the water over her. As I soap her I feel her soft skin and breasts. Even in this hot water her nipples are so hard. ” Hey big brother? do you have a more powerful setting on the shower head?” she asks. I click the shower head on to the jet setting and continue on. Suddenly, she grabs my hand forcing the shower head to her pussy. I avoided looking there until now. My eyes lock onto her pussy, her pussy limps so plump, they bounce against the powerful water, her hips gyrating in agonizing pleasure. Her moans grow louder and louder. I noticed she had let go of my hand, I’ve been holding it there for her since she positioned it and now her hands are exploring me. She looked up at me with a burning want in her eyes, biting her lip as she undid my button and unzipped me. “big brother you take such good care of me. Let me take care of you too.” Her small hands reached into my pants gripping my shaft and I readjusted letting my jeans fall to the floor. “So thick” she whispers between her moans, salivating as she slowly strokes me. Picking her head up she inched toward my cock lightly kissing the tip and running her tongue around it. “big brother you really are so big.” she said as she stuffed me into her mouth. She started slow, as it was a tight fit for her, but as she picked up the speed she went deeper and deeper. I felt her saliva running out of her mouth dripping down my balls. “does she ever suck you like this?” she asked teasingly. “No, she can’t get it down her throat either” I respond. “Oh?” she questioned looking up at me, plunging me deep into her throat, her tongue out licking at my balls. “Big brother, I want you to fuck me. Fill me with your cum.” she begged. “This isn’t a good idea, we shouldn’t even be doing this. Plus you aren’t even on birth control!” I tried to resist. “breed me big brother, fill me, put your child in me.” she moaned.  I couldn’t resist any longer. I lifted her small soaking frame into the air and took her to the bedroom throwing her onto the bed. “Yes big brother stretch my little pussy, ruin me for other men” she begged excitedly. I threw her legs to the sides, her pussy on full display and plunged my face into her crotch. I’ve never tasted such a sweet pussy. She’s so wet, my face covered in her juice as I sucked and licked her clit. Sticking my tongue into her dripping tight hole. Her moans growing louder begging me to fuck her, suddenly she squirted on my face. I stood up in ecstasy at what just happened, my cock hard and pulsating for her. I undress myself and crawl on top of her passionately kissing her deeply. I slowly began to enter her tight wet hole and she let out a long low groan.  I suddenly thrusted deep, I felt her tight pussy explode around me, such a thick cock surely hurt her as it stretched. But she was loving it, begging for more. I fucked her deeply and passionately while fondling her perfect breasts. When I pulled back and stood up she seemed confused. ” I have an idea” I said. She’s probably not even 100 lbs I thought to myself. I picked her up and held her in the air. “I’m going to use you like a flashlight.” I said as I thrust myself into her. Her arms hanging around my neck tightly. I hold her steady while thrusting deep into her. her moans turn into screams of pleasure. Her juices dripped from my balls to the floor as she continued to squirt over and over again. “Big brother!” she yelled out, “Cum inside me, fill me with your cum over and over!” she begged. “I stopped. and gripped her fat ass tighter and said it’s not your pussy anymore, this is my pussy now.” I said forcefully and she gasped in response. “cum in your pussy big brother” she whispered submissively.  I fucked her harder and faster her legs flailing in the air as her screams grew louder, my cock brimming with anticipation ready to cum. Unable to hold back I released pulsing my load deep inside of her, as she felt the warmth she let out a groan of absolute pleasure. “yes big brother, get me pregnant cum, keep cumming don’t stop.” she said. I continued to pump my balls dry draining myself into her, my cum starting to leak out from her tight pussy lips gripping my cock with every pulse. I throw her down onto the bed, her legs spread wide open, her hands quickly touching herself feeling the cum deep inside of her groaning in pleasure. My cum continuously dripped out of her onto her tight little asshole. I approached her, gripping her head forcefully and she looked up at me in shock as I shoved my cum covered cock in her mouth. She happily took it in and began sucking and deepthroating me again, getting me as hard as before. I pulled my cock out of her mouth as she gagged. she began stroking me while sucking on my balls, licking the shaft and tip and back to sucking my balls. Her tongue and mouth feel so good I can’t hold back unloading myself again onto her face then shoving my cock down her throat and dumping the remainder into her throat. “oh big brother, that was everything I ever wanted.” she groaned. While Izzy is gone, your little sister is your cum slut from now on. I’ll stay here all week and you can drain your balls in me over and over again.” she pleaded. “I’ll think about it” I said, “but I’m not done yet.” I grabbed onto her legs and ass and pushed my face into her pussy tasting both of our juices and she writhed in pleasure squirting again. I plunged myself balls deep into her cum filled pussy , my cum exploding out of her with each thrust. “I’m going to fill you with every drop of cum I have before the nights done.”
