Modeling For My Sister by Casper (easyglider@hotmail.com)I was sixteen and my sister Kathy was thirteen when it all began. It was summer vacation and we had plenty of free time together. Our parents were both at their jobs six days per week, so we had the house to ourselves. One day Kathy and I were playing some Poker. Since neither of us had any money, we were gambling with house chores. I wasn't having very good luck and before long, I had a long list of chores to do for Kathy. When I complained to her about all the chores that I would have to do for her, she offered to let me off the hook in exchange for "one little favor." I should have been suspicious when she was vague about what the "little favor" involved, but I took her bait like a dumb fish. Kathy is a very talented artist, and has won numerous prizes for her pen and ink drawings. She said she would trade all the house chores if I would agree to do some modeling work for her. I foolishly agreed to this exchange without asking for some details about what kind of modeling this would be. Once I had agreed to the deal, Kathy excitedly announced "O.K. then, let's get started!" When we got to her bedroom, I asked "so what do you want me to wear for these drawings?" Her hesitation in answering me set off a warning bell in my head. "Ah... er... you won't need to worry about what to wear." "Huh" I asked. "What do you mean?" Kathy looked down at the floor and her face began to turn red. "I mean you won't be wearing any clothes in these drawings!" Now it was my turn to blush. For a moment I stood there in stunned silence with my mouth open in shock! "You mean... you expect me to... pose in the... nude?!! No way!! I won't do it! The deal is off!" Kathy answered my angry tirade with "either you do it or I will tell mom and dad about your little porno collection!" "How did you know about that?!!"I gasped. "I've seen you looking at them in your room while you played with yourself!" "So you spied on me, huh? Did you like what you saw you little voyeur?" Kathy gave me a devilish smile and said "yes, I did enjoy it, and I am gonna enjoy drawing you too!" I argued that I didn't want to have nude drawings of me put on display at art shows, but she reassured me by saying that "I will draw different faces in place of your face. I don't want your face... I just want your body!" I realized that she had me by my balls (figuratively speaking) and I wondered if that might turn out to be literal also! "O.K. sis, you win!" I answered with defeat in my voice. Suddenly I got an inspiration. I had been entertaining sexual fantasies about my sister for a couple of years now. My masturbation sessions were frequently aided by visions of her nubile body. Perhaps I could turn my predicament into a fantasy come true if she would agree to my offer. "I'll pose for you in the nude on one condition." "What's the condition?" asked Kathy. "Since you are going to be seeing me in all my glory, it's only fair that I get to see you naked too! You can have as many drawing sessions with me as you want, only you have to be naked too!" I didn't expect her to agree to this deal without a fight, so I was shocked when she quickly accepted it. The moment of truth had arrived. I began to remove my shirt but Kathy stopped me and said "I want to undress you and then you can undress me!" She finished removing my shirt and sat down on the edge of her bed and beckoned me to stand in front of her. I was wearing a tight fitting pair of jeans and what my lovely little sister was about to do had caused a very obvious bulge to form in my crotch! With Kathy seated on her bed, her eyes were level with my obvious hard-on. Her eyes nervously darted back and forth from my eyes to my crotch and a knowing smile began to form on her face. She slowly reached up to my belt buckle and shakily undid it. After unsnapping my jeans, she slowly pulled down my zipper. Kathy's breathing was becoming more rapid and so was mine! My cock felt like it was about to explode and I could feel a wet spot forming in my briefs! Kathy pulled my jeans down over my hips and down to my ankles and I stepped out of them. She focused her gaze upon my bikini briefs and smiled at me. She then reached up with both hands to begin softly caressing my masculine bulge. "Oh God! Kathy! You are gonna make me cum if you keep doing that!" I was trembling with sexual arousal and my pre-cum had made a large wet spot in my briefs. Kathy slipped her fingers under my waistband and slipped down my last piece of covering. As she pulled the briefs away from my loins, my erection sprang forward and nearly hit her in the face! She let my briefs fall to my ankles and fixed her eyes on my impressive manhood. I was an early developer for my age and already measured a respectable 6 1/2 inches in length and 1inch in diameter. My throbbing erection was standing at a forty-five degree angle and was only a couple of inches from Kathy's mouth. "Wow! It's so big! I've never seen one from this close before!" I could tell she wanted to just reach up and grab it, but couldn't get up the courage to do that right away. Kathy brought her hands up to my hips and began to caress me with her fingertips. Her left hand moved back to my asscheeks and began fondling them while her right hand crept ever closer to my erection. Her hand finally reached my shaft and she wrapped her fingers around my rock-hard cock! "Oh Kathy! That feels so good!" I had never been touched by a girl before, so the effect of my sister's hand around my cock was nearly overpowering! Kathy began to run her hand up and down the length of my erect cock and occasionally stopped to rub the pre-cum all over the tip. Noticing the increasing flow of pre-cum, she asked, "Is this your semen? Have you already had an orgasm?" I answered "No, that is my pre-cum. It starts flowing out when I'm close to cuming!" Kathy looked up at me and said "One of my girlfriends told me about how her boyfriend gets "blue-balls' and how it hurts him. Are you having blue-balls now?" I was barely able to gasp "Oh!... Yes! It hurts too!" What my sister said next almost made my cock boil over! "My girlfriend says she helps her boyfriend get rid of his blue-balls. Would you... like me to... help you?" "Oh Kathy! Yes! Would you please?" Kathy nodded her head yes and said "I want you to undress me first and then I'll take care of you!" I first pulled Kathy's T-shirt over her head. She was wearing a plain cotton bra, which I excitedly unsnapped and slipped, off her shoulders. I got my first good look at real live girl breasts! They were probably no bigger than a B cup, but to me, they were like food for a starving man! I took her breasts in my hands and began to lovingly caress them. Her nipples quickly became erect and when I took one of them into my mouth, Kathy let out a long moan! I reached down and unsnapped her shorts and slipped them down her smooth, shapely legs. Kathy now wore only a pair of pink lace-trimmed panties. I noticed that a wet spot had formed at her pantied crotch, which I knew signaled her own arousal. As I kissed her left breast, my left hand slipped into the back of her panties to fondle her buttocks. Meanwhile, my right hand slipped into the front and moved down to her pubic mound. I let my fingers run through her soft, thin covering of pubic hair before slipping down to her moist labia. Kathy shuddered and moaned as my fingers moved up and down her slit. She squeezed my rock-hard penis in her right hand while the fingers of her other hand slipped into the crack of my asscheeks. I finally slipped off her panties and we lay down on her bed. We both lay on our sides facing each other and let our hands wander over each other's bodies. I ran my fingers through Kathy's blond patch and she raised her leg to give me free access to her now wet and swollen inner labia. I said "Kathy, you are so beautiful!" She responded by giving me a passionate kiss. Her tongue pushed into my mouth where it wrestled with my own. When we came up for air, Kathy pushed me on to my back and laying along side of me, she began to run her hand all over my erection. "Does this feel good?" she asked. " "Yeah! That feels great! Try holding the shaft with your thumb and first two fingers and move up and down" I suggested. "Like this?" "Oh!... Yes!... Like that!" "Your penis feels so warm! It is really nice and soft on the head and the shaft is silky smooth, but at the same time, it feels like iron underneath! Your cock is like a rod of iron in a velvet glove! I hear some girls say they think that penises are ugly! I disagree! Your penis is beautiful! I love the way it looks and feels!" Kathy's words and the pumping action of her hand were bringing me to the edge! "Kathy... I'm about to cum! Ahh... Oh! Yes!!..." I felt my balls tighten just before the orgasmic wave washed over me! My hips bucked up and down and my cock began to shoot wad after wad of white, creamy semen into the air! Some of it landed on my cheek while most of it landed on my chest and belly. Kathy continued to milk me and she had a look of awe on her face. As my orgasm gradually subsided, I relaxed and cuddled my sister. She had a large amount of semen all over the back of her hand, so she got up and went to her bathroom to get a washcloth. She came back and began to clean me up. "That was awesome! God! Do you always ejaculate so much?" "It depends on how often I masturbate. If I go for a few days without doing it, it builds up." This response led Kathy to her next question. "How often... do you... masturbate?" "Oh, I probably do it almost as often as you!" She grinned and said "Ah! I guess that means you masturbate every day too!" I pushed Kathy down onto her back and said, "now it's your turn!" I had decided to give Kathy her first taste of oral sex. I was sure she would enjoy it so much that she would return the favor! I had read all about the techniques for orally pleasuring a woman and was confident I could give my sister a wonderful orgasm! I began kissing her breasts while the fingers of my right hand began to gently caress her labia. Gradually I kissed my way down her body until I reached her belly button. After tonguing it a little, I skipped over my intended destination and began kissing her inner thighs. Kathy was making purring and moaning sounds and when I began kissing up her inner thighs, she spread her legs wider. I worked my middle finger into her moist opening and pumped it in and out. When my tongue began to lick around the outer edge of her vagina, Kathy suddenly grabbed the back of my head in both her hands and pulled my face into her pussy! "Oh!... Ahh... Yes! Oh baby! Lick me!...Ahh!" Kathy was now bucking her hips into my face as I worked my tongue up and down the length of her slit. When my tongue began to work at her swollen clitoris, the intensity of Kathy's moaning greatly increased! "Ohh! Mmm! Ohh!... I'm cuming!... Yes!...Mmm!" I continued to work my tongue over her clit while my finger pumped in and out of her sopping wet hole! After Kathy's orgasm had subsided, she pulled my face up to hers and gave me a passionate kiss. "Oh wow! I never dreamed it could be that good! That was incredible! How can I ever thank you for such a wonderful experience?" "Oh, I think you can find a way to thank me!" I winked at her. A look of recognition suddenly came over her face and she reach down to find my now fully erect cock! "I guess its only fair that I return the favor, huh?" Kathy chuckled. Kathy positioned herself between my spread legs and gazed at my erect manhood. She grabbed the shaft in one hand while the other began to tickle my testicles. She finally moved her head down to my cock head and softly kissed it. Her tongue snaked out and licked the mushroom-shaped head and began to lick up and down the entire length of my shaft. She finally opened her mouth and took me in. I was in ecstacy! She began bobbing up and down on my erection in ernest and I could sense that it would not be long before I gave her a mouthful! "Ohh! Kathy! I'm gonna cum! Ahh...Ohh...Mmm! Yes! Here it comes! Ahh! Oh!..." Kathy kept milking my cock with her mouth an swallowed every drop of semen I offered her! When it was over, we embraced each other and rested. We never got around to doing any sketches that day! We spend the rest of the day giving each other manual and oral pleasure! The next few days were spent similarly, although Kathy did manage to do a few sketches of me. One of her best was a rendition of "michalangelo's David" statue. There was a major difference between David and me though- the David statue didn't sport a raging hard-on! About three weeks later, I celebrated my seventeenth birthday. After our parents had gone to work, Kathy handed me a wrapped box. I opened it and was stunned to find it was a large box of...condoms! I must have had a puzzled look because Kathy said "you'll need to use those with the other gift I'm giving you... my virginity!" We used up that box of condoms in about one week and have been through many more boxes since then! If you have any comments or stories to share, I'd love to hear from you!
