Sex mixed with a little peach lotion that Cara always spread on before going to bed. Almost made me hard just thinking about it. Lying in bed knowing that my sister wanted me to be her "boyfriend" made me a little nervous, but at the same time made me want to just run down the hall and jump her bones again just because I could. She always made me feel like a great guy even when I knew I wasn't being one. Our arguments were just previews of the great sex that we were sure to have when we made up. In many ways we were already in a steady relationship. But labeling ourselves as boyfriend and girlfriend in secret and brother/sister in public was something that I really didn't want to have to do. Cara I'm sure would be fine with it but myself I knew that all it would do was complicate our lives even more than they already were. If she was ugly this would be so much easier! I thought to myself. The next morning I sit across from Cara at the breakfast table. I couldn't help to look into her eyes. They gleamed back at me as if saying, "I love you James." The weekend once again was ours. Our dad once again had a trip for business and mom was going to join him. They were going to leave for the airport right after breakfast as they had a 1015 am plane ride to Atlanta. We watched mom and dad leave, waving goodbye. I turned to Cara and ask, "So what do you want to do?" She replied, "You!" I shook my head in disbelief of her honesty and boldness. "Very honest of you." I replied. "Just being honest, you want me to be honest don't you?" She coyly said. "Well I think that can be arranged." I told Cara in surprise to myself. I think it took her for a loop to as she looked at me with a surprised face. But I was horny and she of course was looking good in her little shorts and as always a small tank top that barely covered anything. It was still early in the morning so she didn't have a bra on yet and I could see her hard nipple poking through as I answered her question. After our little romp last night neither of us had taken a shower and our combined scent could still be smelled ever so slightly in the air. Wondering in my head if our parents had noticed it or not. Wonder if they even knew the smell anymore? "I've got a great idea Cara." I told Cara. "Yes James." She replied. "Why don't we take a good hot shower together, then go out and do something today." I stated. "Sounds fun James!" Cara replied enthusiastically. "I'll go up and start the water." Cara went upstairs to start a hot shower for us and I took the minute in between get a drink of gatorade and a bite of banana. I heard the shower come on upstairs as it always made a squealing noise when you first turn the water on. I was excited to hop in the shower with Cara. The thought of her sexy body all wet and soapy was turning me on and I was always hard. I was hopping up the stairs two at a time. When I got to the top of the stairs Cara came to our parents bedroom door not our bathroom that we shared. She had nothing already stripped down to nothing and I was super excited to get a hold of that ass. I ran to her in the doorway and grabbed her around the waist and hoisted her up in my arms. I passionately kissed her delving my tongue deep in her mouth. I could taste the sweetness from her fruit she ate for breakfast. It was wonderful. I wrapped her up in my arms and carried her to the master bathroom. I pushed her up against the wall next to the plexiglass shower. The glass was already steamed up but I was gonna make it even worse. I pulled her arms up to the wall above her head. Told her to leave them up as I worked my mouth from her neck kissing softly.I made my way down to her breasts, big and perky, nipples hard as can be. I sucked on them hard as she squealed. She loves her tits played with and I was going to enjoy her enjoyment. I released them and flicked them with my tongue. I massaged her tits while I teased those nipples and then I ever so slightly bit the left nipple and she let out a scream. I took my attention away from her tits and started kissing down her stomach, making my way to her sex. I kissed the inside of her thigh and placed my middle finger on her slit. It was glistening from her wetness. So I slid that middle finger in and felt the wetness of her tight little pussy on my finger. It was warm and wet and just felt so good on my finger. I pulled it out and tasted her juice on my finger. Tasted so good, tart with a little musky smell to it. I stood up in her face and kissed her again. Mixing her sweet taste of her mouth with the tart taste of her sex. I turned and walked away stepping toward the shower. Opening the door to allow her access. I quickly, as I was still clothed, undressed much to her liking. She bit her lip as I pulled my underwear off releasing my erect cock. I stepped in the shower and she grabbed me by my dick moving her hand up and down my thick shaft. I turned away and grabbed dad's body wash and put some on the poof that hung on the shower wall. She couldn't get enough of my dick. She grabbed me by my waist from behind and then moved her hand down to my cock again. I started to wash my chest while letting the foam slide down my body to her hand. Using the foam for lubrication she almost made me cum with her expert handjob by the time I had gotten my front washed. She took the poof from me and said, "I'll get the rest." She pulled me back around to face her. She knelt down in front of me and used her hands to soap up my cock and balls. She played with my balls in her hand. She squeezed and moved them around. It felt great. Her ball play had stopped my impending cumshot. She took her hand and worked her way underneath my balls to soap up my ass. I had never been much about getting my ass played with but this was outstanding. She rubbed her soaped up finger over my asshole. Felt weird at first but I got used to it quickly. It was a taboo but of course we were all about breaking all of those rules. The water was running down my body at this point and splashing in her face as she stared my cock. She stood up now and washed the rest of my body. And then handed to poof over to me for me to do her. I turned her to face away from me at first. I pulled her close though and wrapped my arms around her to grab those big beautiful breasts and soap them down with my mom's pomegranate body wash. It smelled so nice as her full breasts cupped in my hand from behind felt as well. I massaged the soap hard as in to trying to knead it into her actual skin. Holding her breasts and subsequently running the foam down to her pussy and massaging it with my free hand was giving me a huge hard on and I needed to release. I pushed her over and made her touch her toes with her ass in the air and her juicy pussy showing quite nicely even with my hard cock. I took my bulging cock in my hand and ran it up and down her reddened slit until it slid in nicely. I took it slow at first then sped up until I was in a fever pitch pounding in and out of that tight pussy. Smacking noises filled the room and water sprayed everywhere in the shower. It splashed up in my face, ran down her ass onto my dick pounding hard into her pussy, She was screaming by now, yelling my name. "James you're going to make me cum!" I was on the brink again. Cara was fucking amazing and I was just about to cum when Cara yelled, "Oh fuck I'm cumming all over you James! I'm cumming, oh fuck." Her words sent me over the edge. I couldn't wait any longer and I came right in her plump swollen pussy. One shot after another, it was like I couldn't stop it. Her pussy just kept squeezing my cock. Her body was screaming what just a moment before she had. She came all over me, my dick and the shower floor. I was spent, all I could think of was glad we were in the shower otherwise there would be a huge mess. I reached over to turn the water off which had gone rather cold since we were in the shower for so long. We moved out of the shower and grabbed some towels that were hanging beside to dry off. Cara came up to me still half wet and grabbed me and kissed me. "Thanks big brother!" I smiled in a reply. "Now what do you want to do for the rest of the day?" She winked and said, "You know what I want to do, I wanna cum like that for as long as our parents are out of town." "Well if you keep putting that pussy anywhere near my dick Cara, you may have to suffer through a lot of cumming the rest of the weekend." I said. She coyly replied, "I'm counting on it!"
