For years now, I have been attracted to my younger sister. It’s not only her gorgeous looks but she is so warm and just a great person to be around. I think she feels the same attraction to me as we always have a great time together. As we have grown older, our sexual feelings have become more bold and stronger.

 

I’m the 28 year old brother of a beautiful 19 year old sandy blonde haired sister. My name is Ron and Amy is my sexy little teenage sister. I'm about 5' 10", well built, light brown hair with blue-green eyes. Not to sound conceded or anything, but I've been called good looking by many women and some have said I look like Mel Gibson. Frankly, I don't see the resemblance but the compliment is appreciated.   My sister Amy came to stay with me for awhile after she broke up with her boyfriend. I have a small two bedroom house I was renting and one bedroom was empty so I eagerly agreed to let her move in. Ever since Amy turned into a teenager, she's been turning men’s heads. Let's just say, she has turned into a fox and is absolutely one HOT woman.   Let me describe my sultry looking sister to you. She stands about five foot three inches tall, weighs about 105 pounds, sandy blonde shoulder length curly hair, sexy blue-green eyes, very nice boobs which are rather large for her small size with very large nipples, a thin waist and a perfect heart shaped ass to die for. I've always found myself checking out her perfect sweet ass around the house while growing up.   Next to my sister's perfect tight little ass, her ample breasts with her very large nipples are her second most sexy attribute. I've seen those swollen erect nipples many times trying to poke thru her swim suit, her t-shirt or sweater. When erect, they swell up, get all puffy and must stick out close to a half an inch, maybe more. I've gotten many a hard-on checking out her sweet ass or her swollen protruding nipples over the years.   If I have to relate Amy's appearance to someone popular, I'd say she resembles the actress, Sarah Jessica Parker, from Sex in the City, only Amy is much prettier than she is. Although I know her bust size is a 35C, from checking out her sexy bra's and panties, I would guess her figure to be around 35-22-34. She has a very nice assortment of Victoria Secret panties, bra's and lingerie in all sorts of sexy colors and erotic designs. Hopefully someday she'll model all of them for me.   For years I've watched this young girl develop into a very sexy woman. Although I've had several hot fantasies about my sexy sister over the years, I never acted on them. Now here was a dream come true, my sister and I living together all alone in my small little house. I dreamed of the sights to behold, seeing her in her sexy lingerie, possibly naked after a bath, my cock was hard constantly. I could only hope to get a chance to make love to her but I wasn't sure how she felt about me sexually.   After about a month of seeing Amy running around my house in various stages of dress and undress, my sexual fantasies were running wild. I'd often catch her wrapped in only a towel heading from the bathroom to her bedroom. Sometimes she would only wear a small t-shirt and sexy panties as she walked around the house. I could see her sweet pussy mound and if I looked real hard, the outline of her sexy pussy lips. Her panty clad ass was always an instant hard-on for me.   I was constantly getting a throbbing hard-on seeing her sexy young hard body. This was driving me crazy but in a very good way. Hell, I couldn't wait to get home from work just to see what she may be wearing that night. Her attire kept getting more daring and sexier and sexier all the time. I swear she was doing this on purpose, trying to seduce me. If she only knew, I was ready to jump her bones for many years now.   My sexy sister would leave her bedroom door open and her soiled sexy panties right on top of her hamper for me to see. I couldn't resist sneaking inside her room and checking them out. I'd find her white crusty pussy secretions dried on the inside of her panties and bring them to my nose to smell the sweet smell of her sex. Then I'd have to wrap them around my thick swollen seven inch shaft and fill them with a huge load of cum, then set them back down for her to find.   We played that game with the panties for a couple of weeks. I know the last time her sheer red lace thong panties were still hot with my huge load of cum when she found them. Only 5 minutes prior did my body shudder in orgasm as my swollen cock spurted three good streams of my hot white cum into the crotch of her panties. Our eyes met in this seductive way as we passed in the hallway seconds after I left her room.   A few days ago, I was walking past the bathroom, which is on the first floor, while Amy was taking a bath. The door is this louvered folding type door which I purposely removed one louver so you can just barely look inside. As I looked in, Amy was sitting in a hot bubble bath with her head back and eyes closed. Her lips were parted as she was breathing heavy.   With all the suds, I couldn't see much of her private skin but you could just imagine how hot and sexy she looked. I'm not sure but I'm think she was rubbing her sweet pussy as I could see the suds moving up and down at the sexy V at the top of her smooth thighs. I pulled my thick cock out and stroked it for several minutes as I watched my sister in her bath. I couldn't take it as I had to run up to my room and finish jerking off as I was so fucking excited.   One morning, still being half asleep, I entered the bathroom with a morning hard-on and forgot to close the bathroom door. While I stood there taking a leak, my morning hard-on subsiding, Amy walked into the bathroom and caught a quick glimpse of my semi-erect cock. She quickly excused herself and retreated upstairs to her bedroom.   She was wearing only a white t-shirt and a pair of sheer pink panties. I could see her white pussy mound and then her white butt cheeks thru the panty material as she turned away. After she left, my cock was so hard that I jerked off right there. I didn't care if she saw me or not, I just had to relieve myself. My sister was driving me crazy with lust for her perfect little hard body.   We could both feel the sexual excitement building between us however we both were scared, still not sure of the other's commitment to go through with anything. So the teasing continued, each day we pushed this game of sexual temptation further and further.   Amy worked out at a local gym regularly, which was how she kept her body in such great shape. On this Saturday afternoon, I was sitting on my recliner watching TV wearing only a thin pair of gym shorts, no underwear and a tank top t-shirt. My cock was already semi-erect as my mind drifted, as always, to the numerous erotic sights and actions that took place in the past few months.   I heard my sister come home but I'll never forget the view as Amy entered the living room, having just returned from the gym, in one of the hottest work out suits I ever saw. Her outfit was a skin tight black spandex body suit which clung so tightly to every inch of her sexy body, leaving absolutely nothing to the imagination. She didn't have one once of fat on that perfect hard body.   I could make out the faint outline of her thin bra as it encased her huge soft breasts. Her shoulders were bare as the top was cut like a tank top. The suit had like a pink thong panty on the outside which accented her pussy mound and sweet butt cheeks perfectly. God, she looked so fucking hot and sexy. I'll bet no guy near her at the gym got anything done that day.   As she entered the living room, she turned her sweet thong covered butt towards me as she checked out what I was watching on the TV. To this day, I can't remember a single word she said to me as I was completely taken in by the view of her perfect heart shaped ass. Her butt could compete with anything you see in Playboy or any of the hottest models, it was simply perfect! I could feel my cock throbbing as it was instantly hard as stone.   As she turned toward me, she said "Yo, earth to Ron! Did you hear what I said?"   As I was about to speak, her eyes widened as they drifted down to my crotch. My thick cock had swelled to its full seven inch length, the huge thick purple head was sticking out of the leg of my shorts and it was throbbing in plain view for her to see. A large drop of pre-cum had already formed at the slit on my throbbing purple knob.   Her wide eyes were locked on the sight of my thick swollen shaft, out in the open for her viewing pleasure. Without thinking, she ran her tongue across her full sexy lips, wetting them and letting out a slight gasp of air. Her right hand dropped to her pussy mound, touching it lightly, without her even realizing she had done so. Her huge breasts moved in and out as her breathing became very heavy.   This was the first time she had ever laid her eyes on her sexy older brother's erect naked cock. She couldn't believe how the sight of her older brother's thick swollen shaft excited her. As she stood there, her nipples poked out like two giant pencil erasers, her breasts heaving up and down as she trembled with sexual excitement. Although it seemed a lot longer, she only gazed upon her brother's thick cock for 10 or 15 seconds.   "Hey Amy, sorry about that but you look so damn sexy in that outfit. I guess I couldn't help myself." I said as I started to cover my huge hard-on.   With her eyes still locked on my swollen cock until I covered it, her face turned red as she blushed realizing she was caressing her pussy as she looked at my swollen cock. She then gave this sultry smile, her eyes were glazed as she said, "Uh no problem, I guess I better go get changed then if you can’t control yourself." Laughing as she turned and ran up the stairs to her bedroom.   My heart was pounding as I sat there thinking about what just had happened. My right hand instinctively dropped and caressed my swollen cock as I ran the sweet images of my sexy sister's workout suit back through my mind. God, she looked so hot I couldn't stand it and she touched herself right before my eyes. That had to mean she was ready and with the right amount of pressure, to fuck her older brother.   I had to do something. Hell, she saw my bare cock all swollen and hard, my blood engorged cock head sticking out in plain view. I thought, this was my chance as I stood up with my huge swollen shaft in my hand. Yes, this game had gone on long enough, I thought. As I stood up, I pulled off my t-shirt and peeled off my shorts.   Completely nude, hard swollen cock in hand, I quietly climbed the carpeted stairs, my heart pounded with sexual excitement as I neared my sister's bedroom door. The door was open about a foot as I slowly and quietly looked inside. Oh my god, what I saw was such a sexy and erotic sight to behold.   Amy had her back to the door, looking into her dresser mirror and had just started to peel that skin tight workout outfit off her sexy little body. I could see both her front in the mirror and her back side at the same time. This doubled mirrored sight was so erotic, so hot and fucking sexy!   I stood there frozen as she peeled it down over her sexy smooth tanned shoulders, lower exposing her lovely shaped back and light blue bra straps. She bent over slightly as she slipped it over that perfect ass, exposing her sweet butt wrapped inside these sheer sexy light blue laced panties. I could see the perfect pale white globes of butt flesh and the sexy crack between those gorgeous butt cheeks. I nearly shot my load all over her bedroom door.   She was wearing one of my favorite Victoria Secret bra and panty sets that she had, a very sheer light blue laced design. I had filled the crotch of those panties with my steamy hot cum only a few days ago. This was a vision of pure sexual excitement as my heart pounded in time with the throbbing thick cock in my hand. My eyes locked on my hot little sister's perfect body only a few feet away.   She lifted one leg, then the other and stepped out of her sexy sweaty workout suit, kicking it across the floor. My hot sexy sister stood there admiring her perfect body in the mirror. Her sexy boobs were stuffed into the matching sheer light blue laced bra which clasped in the front. Her exposed pale white cleavage was simply superb.   Amy always has a nice tan from the spa tanning booths. Along with her perfect tan, she has very erotic and very sexy tan lines. Her tits are creamy white with huge dark swollen nipples outlined by very distinct sexy tan lines. I find her tan lines to be so erotic and simply sexy. I know some people don't like them, but I find them very erotic. To me, it's like being able to see thru the sexy bikini to the hidden treasures underneath, very sexy.   Not knowing I was watching, Amy gently began to cup and caress her tits, causing her nipples to swell even more than they already were. I could see the dark buds pushing thru the sheer material of her sexy bra. My sister tweaked and pulled at her rigid nipples thru the sheer material, rolling them between her sexy little fingers. This was so hot!   I quietly watched, gently stroking my rigid rock hard seven inch shaft as my sexy sister continued touching herself. It suddenly dawned on me, Amy got so sexually aroused seeing my stiff cock that she had to go masturbate herself, much like I had done after seeing her in the bath tub. She was as turned on as I was. Somehow, I felt my cock grow harder as my mind raced over what could happen next.   Amy dropped her right hand across her firm tight tanned abs to the top of her sexy panties and slipped inside. With her eyes and head rolled back, mouth open, her left hand caressing her right nipple, rolling it between her fingers and her right fingers now lightly touching her swollen clit, I again nearly shot my load.   In the mirror, I watched as her fingers cupped her pussy mound and gently rubbed up and down her moist slit. The material of her panties became dark, wet from her juices as she was so excited from seeing her sexy older brother's thick swollen cock. Her mind's eye locked on the vision of her brother's hard sexy erect cock as she touched her forbidden treasure.   "Uuuuuummmmmmmm yessssssssssssss! Ohhhhhhh Ron, your sexy cock is so big and haaarrrrdddddd!" she hissed quietly as she rubbed her swollen and aroused clit.   I watched in disbelief as my hot little sister pushed her sexy butt out as her fingers increased the pressure on her tingling clit. In the mirror, I could see her hand moving faster as her pleasures increased. From behind, I could see her fingers moving up and down between her moist pussy lips, inside her sheer panties. My knees weakened as this was the absolute most erotic sight I ever witnessed. My sexy young sister was masturbating right before my eyes while thinking about my cock.   "Oh yes, that's it Ron, show me that beautiful hard cock of yours!" my sister Amy whispered under her sexually excited breath as she caressed her now soaking wet and excited pussy.   Amy had to support herself with one arm leaning on her dresser while her right hand probed and caressed her quivering swollen clit. She dipped two fingers as deep as she could into her wet pussy. Her body shuddered as she pulled them out and up over, sliding her erect clit between her slick juice covered fingers.   My sexy little sister quietly panted out, "That's it big brother, stroke that big hard cock of yours. Let me see you cum for your little sister! Yeah that's it bro, shoot that hot cum into my panties! Uuuuuuummmmmmm yessssss"   I couldn't take it anymore, watching and listening to my sexy sister masturbating, saying my name and her imagining me stroking my cock in front of her. If I stood there much longer, watching and listening to that, I cum so hard I'd probably shoot a hole right...
