I would never admit it, but my sister is gorgeous. The only aspect that makes it less embarrassing is that she’s my stepsister. My parents split up a few years back. I went off to live with my father outside of L.A. My mom was a doctor up north, and I preferred not to move to a new town. I didn’t like the whole idea of a new school and new friends, especially during my senior year of high school. My dad immediate remarried; to the woman he had been seeing prior to my parent’s split. Stacy was the reason there was a divorce. Stacy moved in with my dad and me, and so did Stacy’s daughter, Monica. Monica was gorgeous, and I was always getting shit at school for it. My friends would always say, “If she was my stepsister, I’d fuck her.” And the truth was, so would I. Stacy was around 5’6” and has long dirty blonde hair. Her hair rested near her breasts, which, although were not very big, were the perkiest things I’d ever seen. The stuck out like a sore thumb. Monica had smooth skin and a really hot face, plus a sweet tight ass to top it off. She had been alternating weekends with her mother and her father, for a few months, but after her dad got remarried, she came to live with us permanently. Ever time I spoke to her; I had to hold myself back from hitting on her. I was always so tempted, and continuously flirted with her. For a while after Monica moved in with us, I was quite reserved with my fantasizing, until I saw her naked. One evening I was walking down the hall, and I heard the shower on. I knew it was Monica, and my head was suddenly filled with sexual perversions. I slowly and quietly cracked the door open in the bathroom. The water was running. I could see in the reflection of the mirror, a slender body on the other side of the shower’s glass doors. Monica stood in the shower, unaware of my presence. I watched for several minutes as she caressed her body with soap and shaved her pussy. Then I heard my dad coming down the hall, and I frantically closed the bathroom door, and walked in the other direction. Nobody had seen me, nor suspected anything. I had a throbbing hard on and needed to jerk off, and I did so, thinking of Monica. Weeks passed and the spring turned into a hot summer. Monica never said anything so neither did I. After graduation and the beginning of summer, Monica and I began to spend more time together. We started going out on “dates.” Most people mistook us for a couple, but we were simply out as “brother and sister.” The sexual tension on my behalf was growing, and I was beginning to sense feeling on her behalf, but I was not sure. I did not want to make a move and be embarrassingly rejected. Then, one day in June, the both of us were swimming outside in my father’s pool. Both my father and Monica’s mother were up at San Francisco, avoiding one of the hottest days of the year. I was swimming around, while Monica sun bathed on a lounge chair. She was tanning in a white flowered bikini, and looked stunning. She had a flat stomach and long golden legs. I got out of the pool to get a soda. While I was drying off, I walked passed Monica, trying not to stare at her. Under her sunglasses, she said, “Mark, can you come here.” I stopped like a deer in headlights and stood there in shock. After an awkward second, I walked over to her chair. On the table next to her, she picked up a bottle of suntan lotion. “Mark, can you put some of this on my back for me, please.” I said, “Sure,” and walked over to her side. She handed me the bottle and sat up near the edge of the lounge chair. I put one knee on the chair and squeezed some of the white liquid into my palm. I gently applied some to her lower back and began to work my way up. I head a slight moan of pleasure, and immediate got a hard on. I was so turned on, and I was convinced she was too. We were so close. She had to want me as bad as I wanted her. And there was only one way to find out. I leaned forward and kissed the back of her neck, moving slowly toward her front. She put her arm over my head as I kissed her and untied her bikini top. She began to lean back on the chair and our lips met. I could taste her berry lip-gloss and her smooth succulent tongue. I wrapped my tongue around hers and removed her top. We continued to kiss passionate as I placed my left hand over her bikini bottom and my right hand over her right breast. She moaned again as I rubbed her bikini bottom. I moved my mouth from her moist lips to her firm breast. She put her left hand on my head and rubbed my hair. “Oh Mark…Ahh…Ahh,” she moaned and groaned. I began to move my head further down. I kissed her stomach and positioned myself in front of her pussy. I kissed her bikini bottom and pulled it down her legs, and over her feet. I inhaled the sweet scent of her pussy and extended my tongue. She placed her hand on my head, as I licked her pussy’s lips. I flattened out my tongue, moving it upward. I tasted the juices of her wet, recently shaven pussy. She was moaning even louder now. “Ahh…Ahh…AHHHHH.” After a few minutes of eating Monica out, I stood up. My hard on created a fixed tent in my bathing suit. I looked into her hazel eyes, and she looked back at me. She smiled and took a deep breath. She sat up I her lounge and put an arm around my leg. With the other hand, she pulled down my bathing suit. My eight-inch cock popped up like a diving board. Her warm hand stroked it for a moment as she opened her mouth and swallowed it whole. She gagged on my entire cock and began to suck on it. Her warm tongue tickled my cock with pleasure. She fondled my balls with one hand as she continued to suck on my cock. The pleasure was overwhelming for me, and I had to sit down. I sat down on the lounge chair, and Monica got up from her knees. On her feet, she bend over, stark naked, to suck my cock. I forced her head down with my hands and she gagged again. Releasing my hands, she brought her head up and asked, “Ready to fuck me?” Without saying anything, I grabbed her hand and turned hr around. Her tanned back and sweet ass faced me. I grabbed her hips and sat her down on my rock hard cock. Her tight pussy wrapped around my fat cock with some difficulty, but after a few minutes, fucking Monica was quite easy. She bounced up and down my cock, moaning and groaning louder than ever. I held her bouncing tits as we continued to fuck. “Oh fuck me Mark. Fuck me. Fuck me. AHHHHHHH. FUCK MEEEE,” she yelled. Then I pulled her up slightly off my cock and stood up. I turned her toward the chair and asked, “Ready to be fucked up your ass, sis?” “Oh yes,” she said. She then bent over, putting one hand on the chairs back rest, and one on the chair’s bottom. While doing so, she exposed her tight pink ass for me to see. I licked my finger and wetted her anus. She giggled slightly from being tickled. I, meanwhile, guided my cock into her ass. Her extremely tight virgin ass squeezed against my cock, as I trusted it back and forth. She was groaning with a mixture of pleasure and pain now. Nonetheless, I continued to fuck her ass. I moved again towards the chair and sat down. Sitting on the chair, I fucked her ass, and turned her slightly so I could suck on her left tit. She was really enjoying it, and so was I. I could not believe I was actually fucking Monica. I leaned back in the lounge, cock still in Monica’s ass. I held her lower hip as she rode my cock, up and down, up and down. After a few more minutes, Monica got up and swung her legs over, turning herself around. Her pussy went back onto my cock, as I fucker her again. I watched as her breasts bounced up and down, as she rubber her clit. Her moaning was getting louder and louder. “Oh Mark…Fuck me. AHHH…OHHH…AHHHH…Oh, Mark I’m going to cum. MAAARK,” she yelled as she came and squirted all over my lower stomach. She warm juiced were all over me, and I was ready to cum as well. “Holy shit,” I said looking at what she had done. “That’s fucking awesome.” She got off of my cock as I stood up. She sat on the lounge and led my cock into her mouth. She sucked on my balls and swallowed my cock. “I’m gonna cum,” I said. Then Monica grabbed my cock and started jerking it rapidly. Faster and faster she worked my cock with her soft and. Up and down until finally, I exploded all over her mouth. She swallowed most of my cum, as the rest of it dripped down her chin and onto her tits. She licked her lips and cleaned my cock dry of the cum. Afterwards, she grabbed her bathing suit and went inside. “This is going to be one hack of a summer,” I though.
