Connie - my sister's friend - part I. By Smog. I had just come home from college to spend some days with the family. 30 minutes after I had taken my stuff to my room I went towards my sister Sarah's room. "You there?" I knocked on the door. "Come in." a voice said from within. "Hey twerp, what is going on ... ... ?" I said loudly as I entered the room. I almost gasped out loudly and I breathed sharply as I saw Connie, my sister's friend, doing dumbbell-curls with some 45 lbs dumbbells. The thick balls of muscle in her biceps were pumping up. She was naked except some black boots and her massive muscles bulged out all over her body. Her firm tit flesh jiggled slightly with each curl as it came to rest on top of her beefy slabs of muscle while deep striations stood out in her cleavage. I was speechless to walk in on her totally naked, and she wasn't even looking embarrassed. I had never seen anyone that looked like Connie. She was like a Greek goddess. Some people look like they have a six pack just because they're skinny, but Connie's whole mid section was just thick with rippling ridges of solid muscle. So defined were her abs - six perfect bricks of muscle, over which she could have done her washing if she so wished. Her legs were as long and thick as trees, each of her thighs were thicker than my waist. The muscles in her arms bulged with every movement. I stared at her arms, knowing instantly that just one of them could overpower my whole body. "What, have you never seen a naked girl before?" Connie snapped. "Not like this." I managed to blurt out even as my mouth must have hung down to the floor. She laid down the dumbbells and grabbed some black lingerie. "How are these?" They were black g-string panties and a lacy, black pushup bra. "Uhmm, uh, they're fine." I shakily said. Connie put on the lingerie, which actually didn't conceal much of her body. Connie came and stood proudly in front of me, bouncing slightly on her toes and giggling. Every time she bounced, it caused her huge calves, already very pronounced from the front and straining the leather of her black boots, to bulge even further until they looked liked they would tear the leather and burst through. Similarly, Connie's thighs were lean, rippling sinew, each at least 25 inches around. Her physique was more astounding then I had ever imagined a woman, nor even just a girl 17 years old. It was big with hard muscle. There was nothing of her 84 kgs that was wasted on fatty tissue - just tanned bulges pushing out between the ravines and gullies that defined her muscle tone. Even the breasts, now hidden behind her bra, could be described as 'athletic', a B sized cup at best. A quick twirl from Connie allowed me a sight of her glutes - the small black panties clung tightly around her hips fully exposing two perfectly-rounded half-globes of rock-solid muscle on an ass less than half the width of her broad shoulders. I couldn't help but marvel at the glorious V-shape formed by her finely-honed torso. Connie pretended to blush when she noticed my eyes lingering on her chest, but I didn't care - I was mesmerized and getting a little scared. "Where is my sister? I asked. "Ohh ... well ... you know ... ..we knew you were coming home today, so she let me be here to welcome you home. Meanwhile she is out doing some shopping." Connie answered. I knew that Connie was all over me to the point of obsession. Some time ago when Connie was sleeping over at our home, I found her personal diaries opened in her bag. In every page of her diaries she wrote my name with all her emotions all over it, sometimes with a heart outlining it, other times with sadness, resentment or even anger. "How in the name of all that is holy did I miss this?" I wondered. I tried to recall every time that I had seen my sister and Connie in the last couple of weeks. Only now did I attach any significance to the fact that whenever he had - only briefly, it must be said - Connie had been wearing unflattering, baggy tops at all times. Connie had always been a flat-chested girl, but now she had blossomed. Her pectorals were now two rippling slabs of muscle, which alone gave her a most impressive cleavage, and topped off with a pair of smallish breasts that would fill a B-cup bra - not that she would ever need a bra, such support was given by her awesome pectorals. Her muscle-pumped breasts were as pert, ripe and full as the best I had ever had the privilege of laying eyes on. I noticed each nipple was as hard and as large as a bullet, and they seemed to grow before my eyes - Connie, apparently, was finding herself excited by her little routine and my amazement. Connie kept up the blushing routine as she 'accidentally' tensed each pectoral in turn, causing her breasts to dance up and down ... up and down ... up and down. Connie's dominant presence, her nakedness and the sight of her muscles bulging and flexing had an effect on me and I gave into the inevitable. My cock was hard and pressing to escape my briefs as I returned toward her. Those baby blue eyes dropped and lifted back with an added smile; she was enjoying this as much as me. I managed to tear my eyes away from Connie's chest, only to discover that there was still more yet to come. Connie's arms hung down by her sides, and yet even with her muscles relaxed, they looked as big, Well, bigger, than my own pipe-cleaners - even when I flexed them. Connie giggled, "You seem like a little boy - all wide-eyed and everything. Haha, and your arms so cute and little, I bet my biceps are twice as big as yours." I grimaced, but my male ego took over and I then flexed ... very little happened. "My turn!" Connie pumped her bicep a few times and then flexed, and as each bicep got bigger and bigger, my mouth dropped lower and lower - so by the time they had reached their bulging peaks, you could have parked a truck in my mouth! I simply could not believe what I was seeing - here, in front of him, stood Connie, a mere girl, and yet her biceps were easily each 16.5 inches round. Connie straightened her arms and smiled as there appeared an enormous horseshoe-shaped bulge in each ... the amount of meat in her triceps totally took my breath away. Connie began to repeatedly flex and then straighten her arms until her muscles were so engorged with blood that her arms had grown by what looked like yet another inch and her biceps and triceps bulged so enormously that they looked like they were ready to explode. The occasional vein snaked beneath the skin, supplying her girl-muscle with the fuel it required. I looked Connie up and down once again, and was only now struck by the power she beamed and the beauty of her appearance. She was to me undoubtedly the most muscular girl, on the planet! The only conspicuous fat on her body remained on her face - her skin was still perfectly soft, smooth and unblemished (save a few freckles), just like the rest of her flawless body - but she wasn't podgy; no, rather her face was oh-so-slightly rounded, with plump red lips, a cute little nose and sparkling blue eyes, all of which was perfectly framed with soft blonde hair, tied into pigtails which just tickled the tops of her delts. She moved closer to me, breathing deeply. "You know! I have always thought that you where a nice looking boy ... ... " she whispered. Gulping nervously, I stepped back just standing there, panting like I had been running. "......and it seems you like what you see?" she said and looked down to my crotch where my member was clearly visible as it was hard as ever. Standing right in front of me, she looked me up and down. "So you like girls with very muscular arms, huh? That surely is appropriate for a little tooth-pick boy like you, isn't it?" she said to me as she gave my dick a little squeeze through my pants. When I didn't answer, she squeezed harder. "Isn't it??" she said with a touch of irritation in her voice. "Yes ... ... ". I quietly said, nodding, " ... but I never liked to be dominated or really wishing I was weaker than any girl!" I said in protest of her groping me. "It's just that ... .." " ... that you now will think of me and my little muscle here next time you go to jerk off??" Connie interrupted me. She slowly raised her arm and flexed her bicep. The muscle bulged up amazingly. "I like that......I became your fantasy ... you can't hide it from me ... Look at me ... I'm sooo muscular now. We can have so much fun exploring this body together" and she inhales making her breasts upon her hard pecs jump to life. "GOD, I want to swallow you whole!" She stated and reached around me just to pull me into her and to her lips invading my mouth with her tongue. "You are mine, you know that? Do you, little boy?" My eyes were wide open and I was almost in shock. "Mmm! Feels like you have worked out a little in the past!" she said, and as if to intimidate me, she let go of me and raised her arms to adjust her ponytail. And no sooner did she raise her arms, her biceps exploded, swelling incredibly into amazing proportion. "Make a muscle for me!" Reluctantly, I flexed my little arm again. "Welllllll....." she cooed as she reached up and felt my arms. ".....not much there huh! Well, now it's my turn." she said. She raised her arms and flexed them so that her biceps grew huge right in front of my eyes. "Look at this power! My muscles are almost twice the size of yours! Look at my biceps! They dwarf your weak, puny arm. You know you want to feel its power! You want to be held by it, to touch it and be controlled by it! Touch my arm and feel what real power is about. After I have you, no other girl or woman will catch your eye again ... come on, Touch it ... Now!" She said in a low commanding voice. As if answering the command in her voice, my hand raised up almost of its own volition and before I knew what I was doing, I was feeling the most awesome muscle on any human that I had ever seen. Her bicep was probably around 17 inches around and it was as hard as steel. It pulsed with power and I could not even compress the tiniest amount, no matter how hard I tried. Against my will, I began to softly moan with pleasure and desire as my hand caressed her magnificent bicep. "Think about how my little muscles grow hard and pumped when I do curls with the heavy weights. Wouldn't you like to see these muscles of mine get pumped up ... harder..bigger ... ?" She teased. "Eeehhh!!!" I said. But I was breathing even harder now. "Ahh, so it's not these bulging, rock-hard girlie muscles that makes you hot?" Connie teased me. She then pumped her enormous biceps again. They grew even more huge and hard and my cock started to grow again. She noticed it and licked her lips. "You just can't help it huh!... you enjoy to feel them!" she said in a low voice and with a trembling hand I squeezed on her bicep feeling its awesome size and hardness. My penis responded by pressing hard against the fabric of my jeans. "Let's go out to have some lunch." She then said, "but first ... ... You want this body, don't you?" she purred, feeling uncontrollably dominant, her muscles pumped up, veins throbbing on her beefy arms and pecs, as she curled her arms, looking from bulge to bulge as they swelled. She then leaned her body closer to me, smiling even broader. She brought her lips close and her breath hot on my ear as she whispered; "Uhhmmm ... ..I'd love to feel your small body against mine ... .! Would you like that, boy; have only to service me? I see how you stare of my big biceps. Do they turn you on?" I swallowed hard. "No, no, Connie, I can't do this," I moaned. "Aren't you sweet?" Connie said, while she forced my arms above my head by gripping both my thumbs in one of her small hands and pushing me up against the wall. "But it's not like you have a choice!" she commented.
