She had just moments before brushed by me and touched my dick hidden in my basketball shorts. Cara was wearing short white shorts that just barely passed her ample buttocks. What made this action so much more daring was that mom was only about five feet away making us lunch. Cara didn't seem to care anymore. She would graze by me even when there was a large amount of room to pass by. No one else seemed to notice. Not that I am complaining, I just think that the once shy girl was now a sexual goddess with seemingly only one thing on her mind, her big brothers dick. Cara ask, "James, are you going to play basketball with the guys today?" I answered, " Naw I'm just in these for fun, of course I am Cara." She looked at me and stuck out her tongue. Even these seemingly innocent little things made me think of her sex. This one was obvious though. "Can I come James?" Cara ask. I shook my head, sure. She looked at me and said, "Good. I think that Brian is so hot!" smiling coyly. Now Brian was a senior as well and was one of my best friends since probably around third grade. She had never mentioned anything about him before so I figured this was just a ploy to throw mom off the scent of us. Cara and I sit down at the table and ate the tuna sandwiches that mom had been making for us. I was terribly hungry and smashed through two of them without a thought. Cara of course only ate one and took twice as much time as me to finish her lunch. Guess she was trying to be ladylike. I ask Cara, "Are you ready to go?" Of course not. What was I thinking? I ask my self rhetorically. She said, "Just a minute." She ran upstairs and grabbed a hoodie, not sure why, it was going to be warm at the gym, but whatever. She came running back down and yelled, `I'm ready!" I grabbed the keys and we went out to the truck and started it up, gave it a minute to warm up the engine and away we went toward the gym. The guys had already text me while she was upstairs so I was in a hurry. Of course Cara wasn't in a hurry. She is never in a hurry unless it's her thing. Cara turned to me, " James pull over please I need to do something real quick." I pulled over as not to piss her off cause I knew she could turn my afternoon with the guys a living hell if she wanted to. I hit the brake and pulled over to the side of the road. She turned to me once more, "James?" I turned to her and said, "Yes Cara." She immediately put her lips to mine and kissed me deeply. It was long and passionate full of lightning crashes and rolling thunders. I ask, "What was that for?" "Just cause I said that to mom back there and I wanted you to know that I'm yours and no one elses James." She assured me. I replied, "I know Cara, I knew what you were doing in the kitchen. But thanks for the reminder." I smiled back at her. I pulled back on to the road after that wake up call and finally made it to the gym. "Hey Brian, Marcus. I see you got started without me huh." I yelled across the gym. Brian yelled back at me, "We didn't know if you were coming, your late!" Cara spoke up, "Sorry that's my fault, you know us girls." "Sorry guys she insisted on coming." I apologized. Marcus just looked at Cara and put his hand on his chin looked her up and down and was like, "Oh it's ok she can watch me wipe you white boys off this court." I smiled, thought in my head, there ya go breaking those black boy stereotypes. I just laughed to myself and ask what we playing "21." "Guess we doing a three man tournament unless your sis over there think she got game James." Brian replied. I joked back, "She got as much game as you Brian." "I doubt it." He replied. Honestly Brian was a varsity basketball player since eighth grade and I knew she had nothing on him. Would be a treat to see Cara out here on the court sweating though. Doubt she would go for it though. Just then I heard, "Sure I'll play with you guys, just no hard fouls I am a lady you know." Marcus seemed excited and I was too. "Ok." I said. "Since Brian is all district he gets Cara." We started the game and Cara actually surprised us all I think. She stepped back and knocked down a couple of threes. Marcus was letting her have it easy though, he didn't wanna piss her off I'm sure. The look on his face told the story. He was playing off of her and wasn't even really defending her. "Marcus, let me have her!" I yelled across the court. Ok now lets see what you can do Cara. She backed up and tried to shoot a three but I blocked it right off her fingertips. I reset and went back behind the three point line. Swoosh! Now that was a pretty shot. We had almost caught up. It was 18-19. They only needed one shot though to win the game. Brian had the ball drove to the rim and shot above Marcus but it rimmed out. Marcus grabbed the rebound and flung it back to me to reset. Now it was me and Cara. One on one. I dribbled to get passed her but damn she played good defense. I turned around and backed in to her. Oh but she had the remedy. She swatted for the ball from behind but missed. She tried again only this time she hooked me and ran her hand over the front of my shorts. Her hand brushing over my dick made me lose my concentration. I misdribbled and the ball went off of the side of my shoe. Their ball. I guess she would give me the same treatment . She backed up on me, pushing me off with her ass. Oh I loved it and if I wasn't on the court with the guys I'd probably have a raging hard on right then. She bounce passed to Brian and he put up a shot that went straight net. Game was over. We got in a group and congratulated each other on a good game. "Especially you Cara." Marcus congratulated. Cara looked at him and smiled. "Well thanks Marcus." "Well I think we all need to hit the showers guys." I exclaimed. "Except you Cara since you stink all the time." I laughed. "Haha good one James." She muttered. "I don't think they have a girls shower in here anyway. You'll just have to wait for us to get done." Marcus explained. "how many stalls they have in there?" Cara ask. "Just three I think sis." I told her. "Ok well when one of you three get done tell me so I can jump in. I still want to go to that movie at 330 James." She claimed. "Ok sis I'll tell the guys." I told Cara. "Thanks James, we already gonna be cutting it close." Cara explained. Me and the guys got in the showers and got washed up quickly. Cara was getting ready to come in the showers when I got finished up and had clothes on. I was bent over on the bench putting my shoes back on when Cara moved across the floor. She had a towel on and nothing else as I could tell. She jumped in the stall that i had just got out of. "Damn it Cara, you can't do that in public around my friends." I yelled at Cara. "Don't worry James, they knew it would take "a girl" a long time in the shower so they already left." She claimed. She turned on the shower and quickly got the steam rolling in the shower room. I heard her squirt some body wash on the loofa and started soaping herself up. I told her I was gonna wait for her to get done outside. I told her to hurry up and stepped outside. I had a devious plan in my head though. I knew there were two entrances to the showers and I was going to use this to my advantage. I made sure she heard the door close behind me and I ran to the other door. I slowly entered the showers and made sure the door didn't make a sound. I crept over to the shower she was in and I could obviously tell that she didn't hear anything. She was soaping and washing the sweat out of her hair. I slammed open the stall and made her scream causing soap to get in her eyes. Haha she couldn't tell who was in there with her. She turned to get away but ran straight into the stall wall. She started yelling, "James! Help me!" I grabbed her from behind and pulled her up close to me. She felt my hard cock push in to her butt cheeks and she again tried to pull away but she just slid to the ground as I clutched her abdomen and turned her over on her back. She finally got the soap out of her eyes at this point and noticed it was me. She stopped fighting and started smacking and cussing me for scaring her so much. "I thought Marcus was going to rape me, James!" She almost cried to me. "I'm sorry baby, I didn't mean to scare you so much. I didn't plan for the soap to be in your eyes." I explained to Cara. She grabbed my neck and kissed me hard. She threw her legs around me and I picked her up in the shower. The water was still on and causing everything to be distorted. She let go of my neck with one of her arms and grabbed my hard cock in her hand and stroked it a few times and aimed my hardness for her wet slit. I slid in with ease to the familiar hole. Oh God it felt so good. Something to be said for the tightness of a young woman. Feels just like that pussy is strangling your dick when you slide in. I leaned on to the wall of the stall and started thrusting into my baby sister pussy as hard as I could. Her tits bounced right in front of me as she hung on to my neck for dear life as i fucked her. Her nipples were hardening and seemed to be asking for me to suck on them. I slowed my thrusting down a bit and pulled her in close to me. I grabbed her tit with my mouth and sucked hard on her hard left nipple. She moaned in ecstasy and her moans made me even hornier. Minding the seemingly dirty floor of the shower stall I layed her down and buried my body with its hard cock in between her open legs. That pussy was spread wide by my raging hard on. I slammed in and out of her pussy as she squealed. The water beat me in the back and felt so good like a little electricity in my body causing my motions to be harder and quicker. The water was bouncing off of my shoulders and hitting her in the face so instead of trying to look at me she had long gave up on that and just had her eyes shut enjoying the fucking that I was giving her in the shower stall. "Fuck me from behind James!" She squealed and pulled me out. She turned her body over slinging her right leg over top of my head and to my side bending her back up and arching that ass up to my waiting cock. This was one of my favorite views of Cara. Perfect view of her dripping wet pussy, her pink rosebud asshole and the perfect view of her hot ass. I love spanking that ass. I try to make sure and leave marks when I spank her for her to remember me by. I grabbed her by both sides of her hips pulled her even closer and rammed my massive hard on in to her waiting pussy. She cried in pleasure and looked back at me with those eyes that cried "make me cum." That tight pussy had me close to cumming but I wasn't ready to. I wanted to make this last forever. Meanwhile that rose bud of an asshole was just staring at me. I wanted to see if it tasted as good as it looked. I pulled out of that pussy. She looked back at me and looked disappointed. "Don't worry Cara, I'm gonna make it worth your while!" I explained. I slid my body back a little bit and buried my tongue into her asshole. She groaned for a second seemingly startled and then started moaning as she got used to the feeling. I licked up and down and then in a circle around her rose bud. I slipped my tongut down to her pussy lips and then back up to her ass. She was going wild, she didn't know what to do. I then took my right thumb and encircled her asshole and the pressed down into it slowly. I didn't penetrate but gave her the impression I was going to. She pushed her ass back into me. I took this as an invitation and so I grabbed her body wash and squirted a little bit on her asshole. She jumped startled by the coolness from the bottle. I rubbed my thumb into the greasy body wash and then pressed this time penetrating her. "It hurts, James." She protested. "Don't worry, let me get past the sphincter and then it will feel amazing baby." I reassured. I got past and started moving back and forth first with my thumb and then I pulled out and then I put some wash on two fingers and spread her ass open with my my two lubed fingers. She cringed at first and then became receptive of the penetration. "I'm going to fuck your ass hard Cara!" I excitedly told her. She first seemed skeptical of the insinuation, but I assured her that it would feel amazing and she would love it. She grabbed her own ass cheeks and spread them for me. My baby sister trusted me with all of her heart and with her ass. I didn't tell her I was going to fuck her with my rock hard cock that had been layig in wait for the last several minute to pentrate that asshole. I continues to fuck her ass with my fingers for another minute. She grinded into the motion and was thoroughly enjoying it when I suddenly pulled them out. I grabbed the body wash one for time and squirted some in my hand. I stroked my hard dick with it for a second and then rubbed some more on her gaping asshole, still open from my two finger fucking from before. "No, James it won't fit you're too big for my little asshole!" Cara exclaimed. "Trust me Cara I am going to fuck and cum in your ass right now today." I warned. I grabbed her hips as she tried to move away from my waiting cock. I pulled her close to me and put the head of my cock at her anal entrance. I pushed into her and she squealed trying not to be too loud in case someone was out on the courts. I covered her mouth with the hand that had just a few moments before was in her own ass. I'm sure she didn't notice this. I rubbed the two fingers over her lips as I pushed my entire cock in her tight little ass. The soap made for a slippery ass to fuck and I slid in and out with just a slight resistance. Oh my God it felt so good. So warm and so tight. I fucked her little ass, watched the water that was now cooling off hitting her in her arched back. After only a few minutes of this she dropped her head and came. Which triggered me to cum in her ass so hard she could feel my streams of cum land in her ass. I pulled out and finished cumming on her asshole. The water quickly made my cum disappear off of her ass as she was still bent over with her ass in the air. She turned around to me and said, "Now you made my asshole a cummy mess, I'm gonna need you to clean that up!"
