My girlfriend has muscles. By Smog. I came home from work on this Friday afternoon. I live in an apartment with my girlfriend, Connie. "Hey, anyone here?" I shouted as I entered the apartment. "In here, honey!" Connie's voice sang out from the bedroom. I entered the bedroom and there was Connie. She was standing in front of our mirror, posing, flexing her awesome muscles. "What do you say, honey?" she asked me as she raised her arms and flexed her huge biceps, "they are so pumped today!" I went over to her and stood behind her. If I was not a head higher than her, she would have blocked me out from the mirror completely. Her body was so heavily muscled and her back so wide that I could hide behind her. "You look awesome, baby!" I said and bowed down and kissed her neck while my hands went to her biceps, "flex them again!" Connie closed her eyes when I kissed her neck, but she brought her forearms down and then up again, making those big biceps swell under my hands. "I just love to feel your muscles bulge!" I whispered in her ear. She just moaned and leaned her body back against mine a little. Her hands went behind my neck, making her awesome biceps bulge against my cheeks. I let my hands take the tour down her pecs, feeling those iron plates of steel and eventually cupping her small but firm breasts, caressing them. Connie started to moan a little and tightened the grip around my neck a little. I started to feel a stirring in my groin as my member where pushed in between Connie's round, hard, bowling-ball buttocks. I turned my head and kissed her hard balled up bicep, licking it a little. "Uhm, baby!" she moaned, "tell me what you like the most about me!" Connie brought her arms down and laid her hands upon mine as I was cupping her breasts. My arms got caught in a tight grip between her swelling biceps and her heavy lats that started to fan out. Her back was getting so broad that my arms were forced outwards and I was being crushed against her bulging back muscles. "Ooofff!!" I gasped and Connie released me, turned towards me and put her hands on my chest. In the mirror I could see her tanned buttocks, round and hard as bowling-balls. She flexed her gluteus against one another, crushing them together in a frenzy of power. Her small G-string slid up even higher on her graphically power-packed ass, while even more material disappeared between the rocks of her muscular lower body. My cock was straining my jeans now and Connie knew it. "So..what do you like the most? My little biceps maybe?" She asked and backed away from me and raised her heavy, meaty arms leaving me standing there with my cock in a tent. She looked down at it, smiled and licked her lips sensually. "Hey, hey, you have to restrain yourself a little. I want to show you my little biceps first! I know you like them!" she said and in an instant she flexed her huge biceps making them jump on her arms. "MY GOD", I said aloud, "please don't stop!!!" She relaxed them and flexed them again, slowly, and they looked even bigger this time. I felt myself getting very, very turned on. "Does it look like a ball?" she cooed. "Yes it does. A beach-ball!!" I said almost trembling now. Connie kept flexing her biceps slowly, up and down. They grew bigger and bigger with each flex. "Come here baby!" She said. "Come here and feel my bicep!" I came to her, and felt her bicep as she asked! She flexed it while I kept my hand on it. It grew bigger and bigger in my hand with each flex. Connie looked down at the bulge in my pants. "Oh, I love that I can turn you on just by flexing my little muscles!" She whispered. Then she bent down a little and picked me up by my waist, pushed me against the wall and told me to unzip. I was in mid air, against the wall unzipping my pants and dropping them to the floor. I then pulled down my underwear and my hard on was right in Connie's face. She took me in her mouth and literally moved me in and out of her mouth with her huge arms. I looked down and saw nothing but massive muscle, beautiful breasts supported by huge pecs and Connie's mouth on my hard on, going in and out. I just could not stand it anymore and came!!!! She dropped me like a lead balloon and started to flex her biceps again. "There! Now that you will not come again that fast, we can move on the fun part!" Connie said. Connie pushed me onto my back on our bed. Connie stood over me, her legs apart, her fists on her hips, like a supergirl. I stared dazedly up at her, conscious of nothing but the mega-massive bulk of the mega-muscular physique which loomed over me. She started to flex her huge biceps and at the same time flexed her pecs, which made her pecs "jump" up and down. I could feel a stirring in my groin now. My eyes wandered up and down Connie's incredible body, taking in the stunning sight of her huge, massive muscles while my cock once more, slowly but persistent, rose to the occasion. "There we go!" She said, referring to my now raging hard on standing straight up. She crawled over me until her lower regions where right above my cock. She lowered herself onto my cock, guiding it in with her right hand. She was so tight and muscular down there, she had to use some force to get my cock in her pussy. "Awww, it hurts." I cried out. "Don't be such a wimpy-boy!" Connie whispered and forced my cock as far into her as she could, while I could just lay there, whimpering and moaning. When taking in a good 12 cm, Connie just could not take more of me inside her, her pussy was just too tight and muscular. As she realised that, she started to fuck my brains out, while positioned with one knee on each side of my legs and her hands flat on the bed right beside my head. Still in pain but also with some pleasure growing, I grabbed Connie's buns with my hands. Her buns where hard, firm and round and they felt so good as she moved them up and down while humping my shaft. I turned my head and looked to the side, seeing a gigantic pillar of muscle that's where her forearm. Connie increased the speed of her movements and now and then she grunted sexily. All of a sudden, she sat straight up, arched her back, which made her small breasts pointing straight up at the ceiling, and locked her hands behind her head making those killer biceps overtake her frame, threatening to burst angrily through her skin any second. "Don't you just love to be fucked by your great big muscle-girl, tell me how bad you want me.......!" she gasped, flexing her heavily muscled arms above her. I could only make a gasping sound as I put a hand, tentatively, on her midsection. It offered no comfort beneath, it was hard as stone. My hands continued up her abs and I felt the marvellous muscles ripple and bulge with her movements and as my hands reached up to grasp her hard, pumped up pecs, I could hold back no longer. Just then, I came to climax, instinctively grabbing Connie's breasts and squeezing them, but they hardly moved, they were almost as hard as the rest of her. As my orgasm finished, Connie's had only just began as she carried on thrusting relentlessly away. I was back into a world of pain. "Stooooop!" I shouted, but Connie was lost in a world of passion and continued unaware of the pain she was causing me. As she moved back and forth, back and forth, she lifted her hair up, letting it fall through her fingers, her upper body stretching, her muscles stretching with her. All of a sudden, her arms dropped to a carrying position, held out to either side, it was as if she was holding a dumbbell in each hand. Her entire body flexed as she came to orgasm, cables of veins running all over her upper body, each muscle bulging to its limit. She relaxed, moved back, and thrust forward again, a second orgasm. I just yelped out in pain as she had a second orgasm, flexing and groaning along with it. She moved back and thrust again, harder. A drip of sweat flung itself from one of Connie's nipples onto my face as her body flexed again. She moved back and I knew this was to be the final thrust, the final orgasm ... and the biggest. As she moved back she brought her hands to her face, bowing her head, her upper body in a defensive, protective position, her hands clenched into fists as beads of sweat ran down her arms. She thrust herself forward with every ounce of power she could muster, throwing her arms down to the side again, fully flexed, her head looking skyward. Pouting her chest, she flexed every muscle in her body, her pussy tightened causing me to yelp once more out of pain and in awe of the explosion of muscle before me. Connie gave out a last, girly scream of excitement, her body shining with sweat, her biceps bulging, her abs bulging, her breasts pouted out, her legs fully flexed as the mass of muscle squeezed my legs together. And then it was over and Connie relaxed. Sweaty but hardly worn out, Connie began to crawl back from my body but I gasped loudly as I was dragged down the bed with her, her strong pussy not letting go of my manhood. Connie giggled and put her hands on my torso and lifted herself up forcing my cock to slip out of her. Connie walked over to the mirror. Her body glistened; cables of veins ran over her biceps, shoulders and legs, a few over her stomach. She did a double-bicep flex. Mounds of gorgeously tanned muscle blossomed from her arms. She pumped her arms a few times, watching the ebb and flow of her huge bicep raise and lower majestically. She then dug the front of her foot into the carpet and flexed her thigh, deeply striated muscled bulged hugely from her leg, massive teardrops of hardened flesh hung over her kneecap. I swallowed, both in fear and lust at the impressive display my girlfriend was exhibiting. "I am a Goddess, I love my body" Connie breathed as she caressed her hard muscles lovingly. Flexing her big biceps in a double biceps pose again, she turned towards me. "I feel like a Supergirl!" Connie shouted, and I had to admit that she looked like one, a perfect specimen of muscularity and femininity. She came over to where I laid on the bed, bowed down and kissed me on my forehead. "Ahhh, that was lovely!" she sighed. "Don't you just love that I am so much stronger than you?" "Yes baby, you know I do!" I said and got up, my legs shaking slightly. "I need something to drink. Do you want anything?" I asked and went out in the kitchen where I got two beers out of the fridge. "Yes, a beer would be nice, honey!" she shouted. "Remember that we have to go out tonight. We are invited to dinner at John and Susan's!" "Ohh man ... " I said, "Do we really need to go?" To be continued ... ...
