My Sister's Boyfriend By Jennifer Wind This story is a work of fiction I've always had a secret crush on my sister's boyfriend from the very first time my sister brought him home and I saw him. They came home from college to meet my parents and I fell for his wavy blond hair, piercing eyes and hunky bod. There wasn't anything like him at our high school. My sister Alison and I were always very close even though she is 5 years older than me. Alison always told me her secrets and all that she did at school. I use to lie awake at night playing with myself after Ali told me about how she and Greg had sex and how good it was, his big cock sliding into her pussy fucking her or how he would lick all over her body from her breasts down to her slick pussy, sucking on her clit while he fingered her. I loved those fantasies of Greg having his way with me. Rubbing my pussy thru my panties till they got nice and wet and slipping a finger deep inside me, pretending it was Greg's hard throbbing cock as I slowly fingered my sweet little pussy and played with my breasts. I would whimper quietly into my pillow as I cummed. That first summer Alison brought Greg home with her for a fortnight. That morning as we all sat down to breakfast, dad complained he had too much to do that day with mum and couldn't work on the yard. Greg said he would love to help and Alison could join mum and dad on their shopping trip. They all agreed it was a good idea and I said I wasn't feeling well and wanted to stay home. Mum gave me a kiss and told me to stay cool. After they all left I changed into a white bikini top and short shorts and watched Greg thru my bedroom window. He was so hot, looking all tanned and sweaty, glistening in the sun as he mowed the lawn. I felt my pussy getting moist from watching him. My hands caressed my breasts thru the thin material of my bikini top. Nipples getting harder, aching as I pulled on them. I lay on my stomach on my bed as my hand reached underneath me to my now wet pussy, rubbing myself thru my shorts. I was lost in my own little world as I slid my hand down my shorts, rubbing my clit and lips. I moaned softly as my finger slid inside my lips wishing it were Greg's cock instead. My hips were grinding into the bed as I fingered myself. First one then two fingers pushing deep into my pussy. The shorts were getting so damp from my juices I would have to wash them before mum got home. I felt the wave of pleasure from my orgasm hit me, deep within my belly making my little body spasm and shudder. I rolled over and slipped my shorts off letting the cool air reach my sweet hot little pussy. I lazily rubbed my clit in slow circles savouring the feeling. Just then the lawn mower stopped and Greg was finishing up. A nasty thought entered my head and I knew I wanted Greg to have me. I got up and put on the bottoms to my bikini and raced downstairs to the kithen. I fixed two glasses of lemonade and brought them outside."Hi Greg, are you thirsty?" " Thanks Jennie that was nice of you " Greg took the lemonade from me and drank it down quickly. He proceeded to make small talk with me and I giggled at his jokes and playfully touched him. I took an ice cube from my drink and started to suck on it and lick it in front of Greg. I held it and stuck out my tongue letting the dripping water hit my mouth, tounge and cheeks." It's so warm today " I said as I rubbed another ice cube over my lips and neck, then down around my chest. Greg was turning red but kept looking at me. I could see a bulge in his shorts. I ran over to the side of the house and got the garden hose." Greg can you cool me off with the hose pretty please "I pretended to trip so the sticky sweet lemonade poured all down my stomach and legs." Well now you have to I'm all sticky " I said with a pout. Greg took the hose and put it on mist and sprayed me down, it felt so good. The water made my white bikini see thru and by now Greg couldn't keep his eyes off me. I grabbed the hose and sprayed him laughing and giggling." You can't catch me," I yelled as I ran around spraying him. Greg grabbed me and we fell to the ground, as the hose wrapped around are legs. I was on the bottom and I kissed him quickly as I felt his cock pressing into me." Jennie please we can't do this" " You're my girlfriends little sister" "Please Greg please " I whispered "I'll be 16 soon" my hand had begun rubbing his cock thru his shorts and I could feel his hardness throbbing against it." Alison's told me all about you two and I want to know how it feels, besides I'll tell daddy about it and today as well if you don't " Greg gave in and sighed which turned into a groan as I slipped my hand down his shorts. We went inside the house and got into the shower to rinse off. I slid my bikini off. I'm 5'6, 7 stone 5 pounds (that's 103 lbs) 32b and short brown hair and deep brown eyes. Greg's arms pulled me close and I tilted my head up to kiss him. His tongue slipped into my mouth as his hands caressed my young body. I moaned softly and slid his shorts off, our clothes in a pile in the back of the shower. His hands pulled and caressed my breasts and nipples making them so hard and red. I reached down and took his long hard cock into my hand slowly sliding it up and down. I felt one of his hands reach down to my butt and start massing the cheeks. One of his fingers would hit my lips and I would shudder and try to press against it. Just then his middle finger slid into my pussy and I gasped pushing up into his hand. He fingered me like this while I kept jerking him off. My lips were clinging to his finger as he pumped in and out of my tight pussy. I came as he kissed me longingly, tounges entwined. Greg asked me if I had ever sucked a cock before. I lied and said yes. He gently pushed me down on my knees in the tub told me to suck him. I licked up and down his shaft while still trying to rub his cock. He was moaning and talking dirty to me telling me to suck it. His hands grabbed my hair and guided my head; I opened my lips and felt his throbbing cock slide into my mouth. I started to gag as more of it went down my throat. He was slowly fucking my mouth. It took a little to get used to it, but I liked the taste and feeling him slide over my tounge. I felt Greg's ass get tighter as he pulled back some, his cum shooting into my mouth filling me up. Most of it dribbled out of my mouth and onto my breasts and stomach as I gagged and coughed. Greg smiled and said that was one of the best blowjobs he had ever had. We got out of the shower and Greg sat me on the countertop. He pulled my legs apart and started to kiss his way down my body. Down my neck around my breasts and nipples, sucking them into his mouth one at a time, licking his cum off my skin as well. I felt his hands massage my inner thighs as I whimpered please. His fingers spread my lips apart and his tongue slid up from the bottom of my pussy to my clit slowly teasing me. I cried out and pushed against his mouth wanting more of his tounge. He licked and sucked on my clit and pussy, my lips turning red, swelling. I tried to grind my pussy into his mouth, as I wanted to cum badly. My 15-year-old body had never felt anything like this. I almost screamed as I came against his mouth trying to push myself into him. Greg got up and we kissed for a bit. He pulled me off the counter and turned me around." This is how your sister likes it " he said. I leaned over and spread my legs as I felt the tip of his cock rub up against my pussy. I had lost my virginity earlier that year to Alison's dildo and later a boy in my class. He slid into me, that thick hard cock filling me up like the dildo did. I pushed back wanting more of him. I felt him reach under me and start rubbing my clit as he fucked me. We were both moaning and getting lost in each other. Greg made me cum 3 times from fucking him. I could feel his cock start to throb my lips clinging to him, he pulled out and started to thrust against my butt cheeks, I looked over my shoulder and saw him shoot his milky white cum on my butt and lower back. He took his cock and rubbed it between my cheeks rubbing the cum all into my skin. The sex was incredible just like Alison said. We rinsed off in the shower making out some and I promised not to tell daddy or Alison as long as we had sex whenever we could.
