Monica the bully. By Smog. The party at the school was really taking off. My friends and some of the girls from our class were sitting at a table chatting away, having a good time. Some of the girls had brought other friends to the party and the conversation was loose and exiting. At some point I went to the bar to get a couple of beers. Standing at the bar, waiting for my beers, I looked around at the people partying. My eyes settled upon Monica, one of the schools bullys. She is one of the bad girls in my school and she is really into weightlifting and bodybuilding. I don't mind really, but she has created a new "sport" for her own amusement. She will pin a boy against a wall while she sticks her hand down his pants and gropes him. Being cheered on by her friends, she would try to make him hard as fast as possible. The ultimate goal was to make him shoot a load in his pants, which with her it always happened very fast. The victims were too embarrassed to report it. I surely never told anyone when she had done it to me. Luckily there had been no audience at the time. Ever since the episode, I was trying to avoid contact with Monica, but I could not help notice her muscles when I saw her. Seeing her muscles bulge and flex made my groin tingle and stir, it was not like she went around flexing and showing off constantly, you had to look just at the right time to see her muscles expand and flex and it always ended too quickly Monica was standing talking to some other girls. I could not help but stare at her for a moment, and just that second she raised her arms behind her head to adjust her ponytail. The movement of her arms made her biceps explode in size, the tight fitting, long-sleeved sweater she wore made no effort of hiding the bulging biceps that rose from both her arms. I could wagely hear the girls talking. "Jesus, Monica!" a girl named Susan said, looking at her left bicep, "You're getting bigger everyday!" "I know, Susan! Look at this huge, sexy peak!" Monica responded, and slowly began to curl her right arm again and I could see the enormous swelling of her right sleeve as her bicep stretching the fabric of her sleeve. I felt a stirring in my crotch as my penis responded to the sight of Monica's bicep growing. She flexed harder and her bicep rose higher. She happily tapped it with her finger. "You're absolutely amazing, Monica," another girl, Rachel added. "I could never find the willpower to develop a body like yours." A third girl, Michelle, reached out and tried to squeeze Monica's huge bicep, "If you get any bigger, girl, you're gonna pop!" Monica just smiled. "Look at yourselves, Skinny legs?scrawny shoulders, "she turned to Susan. "And look at those pathetic little arms!" "My boyfriend loves my arms," Susan shot back. She moved close to Monica and flexed a small but hard, defined biceps. Monica reached out, grasped Susan's flexed arm between her fingers and began to squeeze. Susan flexed harder, but Monica crushed the muscle gradually, painfully until her fingers and thumb almost touched. Susan yelped and tried in vain to pull her arm away. Monica chuckled at the struggling brunette, then let go. "Oh, did that hurt? I'm so sorry," Monica said with mock concern. "Here, I'll give you a chance." She raised an outstretched arm. "Squeeze mine." Embarrassed and desperate to prove herself, Susan stepped up face-to-face with the bigger girl. Monica flexed her right biceps, "Go ahead," she challenged. Susan glanced to see the muscles harden and expand to intimidating proportions. The brunette hesitated for a moment. "Go ahead," Monica taunted. "Here's your chance for payback." Susan slapped her hand hard on Monica's huge, flexed biceps, and then grabbed the muscle. The sheer size of Monica's arm forced her to fully extend her fingers, just to get a grip. She began to squeeze intensely, the muscles of her own arm tensing with the effort, but Monica's powerful biceps did not budge. Susan applied more pressure, mustering all her strength. Still, she could not dent Monica's rock solid symbol of strength. Monica giggled at Susan's futile attempt. "Come on. Is that all you've got?" Susan tried again, grunting with the exertion. But it was hopeless. Monica's arm was just too big and too hard. She let go. Monica laughed. "What a wimp!" I noticed that the blonde girl, Michelle, was staring intently at Monica. Her tongue licked her slightly parted lips and her hands clasped her thighs as if she were now afraid that she was going to reach out and grab something she shouldn't. When Monica flexed one mighty bicep again, the blonde's chest started heaving and she slid her left hand inside her skin-tight pants and touched herself. Monica looked at her hard, peeked bicep and then she turned to the blonde, smiled and laid a heavy muscled arm around her shoulders and walked away with her. The bartender brought me my beers and I went to my friends. After some time I felt the need to take a piss and I went to the restroom. On my way there I went by a storage room, and I heard noises coming from within. "What is going on here?" I thought and I snuck up and peeked through the small opening in the doorway and almost let out a loud gasp at what I saw. Monica stood with her side towards me, with Michelle in front of her. Michelle´s hands were all over Monica's body and both girls seemed to be lost in the moment. The blond girl, Michelle, sensually ran her hands over Monica's huge, hard biceps, very visible under the stretched fabric of her sweater as she stood there, hands on her hips. Monica raised her arm and flexed her humongous bicep. The bicep rose to its 18" size of hard female muscle. "So, what do you say to this little pussy-girl!" she asked in a demanding voice. "Uhhh, you are sooo fantastic! Your muscles are soooo huge and sexy!" Michelle answered in a whisper and placed her hand on Monica's flexed bicep and caressed it. I could see that Michelle's small hand could not cover the whole of Monica's big bicep and the awesome sight would not let my eyes off, so I just stood there, mouth hanging open, glancing. Monica closed her eyes and enjoyed Michelle caressing her bicep, relaxing and flexing it randomly. "Uhmmm?" she sighed, when Michelle started to kiss her bicep too, "?I like that little girl!" She then proceeded to raise her other hand and flex that bicep too. Slowly she bent her arm and her bicep just grew and grew, like in slow-motion, to its huge size. Michelle laid her hand on it. "OMG! It's just so huge and hard, you must have spent so much time pumping iron!" she said in awe. "Ohh yeah, so I have!" Monica pumped her biceps a few times making them grow even bigger, almost tearing through the fabric, "I just love to have muscles?? big, hard girl muscles!" She pumped her biceps again making Michelle's fingers spread out by their size. Monica then laid her hand on Michelle's shoulder, pushing down so she dropped to her knees. Michelle kissed Monica's boots. She caressed her strong muscular calves and thighs and then clasped her teeth on her panties and pulled them down. She took her hands and massaged Monica's legs and butt. She brought her lips to Monica's crotch and started to make out with her pussy. Monica was standing with her eyes closed, holding her hands on Michelle's head, forcing her face in her pussy. When she came, her lovejuices sprayed all over Michelle. "Ahhh!" Monica moaned in ecstasy. "That was gooood! Now get the hell out of here before I spank you, you little musclegirl slutt." She raised her right arm and flexed her bicep which grew to tremendous proportions again. I could not help but gasp out loudly at the sight. Monica turned her head towards me catching my eyes with hers. A wicked smile was on her face. I turned and ran for the boy's restroom. As I was taking a leak, my mind kept trying to show pictures of Monica's bicep, bulging out of her arm, stretching the fabric of her clothes. I found it so sexy, that my cock started to react and it became difficult to piss. After a brief struggle, I started to calm down and walked out from the restroom. Standing right outside the restroom, as if just waiting for me, was Monica. "Hi!" she said in a low voice, "You're looking real good today boy". She took a step closer and placed a hand on my shoulder. "I noticed you were looking at me before! Was there something you liked about what u saw? Maybe this?" Looking me straight in the eye, she raised her right arm and flexed her huge bicep again and even though it was still hidden under the fabric of her blouse, it looked so huge and massive. My erection was back with a vengeance as I gaped at the muscular Amazon's huge bicep. Clenching her fist under my nose, she flexed again. "Take a look at that bicep," she said. "Not bad for a seventeen-year-old girl, huh?" Jeez, her arm made mine look like a broomstick by comparison! "ehhh??!" I said, almost in shock. The girl saw the scared look on my face, and laughed, smiled demurely and turned around halfway, then turned back and looked at me, waiting for my reaction. I was just standing there, panting like I had been running. " It seems you like what you see after all?" she said and looked down to my crotch where my member was clearly visible as it was hard as ever. "ohh..ye...yees!" I stammered in a low ashamed voice. "You look very sexy! Your muscles are so huge and sexy!" She took hold of my hand and led it under her blouse before I could even muster a thought. "Feel how hard my abs is!" she whispered proudly. She led my hand over her ridged abdominal and I could feel the hard bumps and valleys of her washboard abs. "Uhmm, feel my abs, caress them ..!" she whispered. She took my hand out again. "You are going to adore my little muscles. Check out these guns of mine, they are 18" of raw, girl power!"She bragged. She rolled up her sleeves and the biceps became visible.Slowly she pumped her arms and flexed her biceps. They bulged up amazingly, huge and hard. Veins visible in her arms, and ohh?her biceps looked so muscular. "Feel them. Feel the huge girl muscles of mine!" She demanded. She was unsurprisingly proud of her muscle-bound physique Trembling a little, I put my hand on her arm tracing the shape of her biceps and squeezed a bit at the bulging mounds of raw muscle. My hand didn't make it even halfway around. Her biceps were so incredibly hard and muscular. Her arms were so much thicker than mine, and her muscles put mine to shame. "O My God......!" was all I could get out in a whisper. "Do you like what you see and feel?" she grunted. "I bet you've never thought a girl could be so big and muscular" she continued, smiling through a teen's face built upon a middle-aged bodybuilder's frame. "Ohh yees?!" I said and my hands couldn't stop caressing the huge, bulging biceps that Monica was flexing up. She closed her eyes and stood there, obviously enjoying my touch. "Uhmm?!" she whispered, "That's right...feel my hard biceps!...Uhhh...yes...kiss it, kiss the huge muscle!" I put my mouth against the soft skin, stretching over the huge, hard bicep of her right arm. Monica flexed it even harder, which almost made me dizzy with excitement. "Uhhmm!" she purred, opened her eyes, gave me a quick, knowing smile, relaxed her arm and put her hand under my chin, lifting it up a little. Then she raised her arm and flexed her immensely huge bicep again. "What are you going to do with me? Please don't hurt me!" I whimpered. "Well, if you must know little man, I'm thinking about getting me a boyfriend. But I want to make sure he'll be able to satisfy me, first." Monica put her hand on the back of my thigh. "Just like you did once before, boy!" She slowly moved her hand up until she reached my ass. She dug her strong fingers into my left cheek. I bit my lip to handle the pain. She let go of my ass and moved her hand to my crotch. She easily slapped my hands away. I became more worried. "Please Monica", I whispered. Monica ignored me. She pulled my groin toward her. My heart raced and my penis responded by pressing hard against the fabric of my jeans. "Come on now. I think it's cute. I think YOU'RE cute." She touched my chin, gently moving my head back towards her, keeping her biceps flexed. "I'm sure you would like to feel this little girl's biceps and caressing these huge, hard muscles of mine." She leaned against the wall, stretching her arm to let her tight sleeve pull higher to show more of her biceps and watched my eyes dart toward them, with lust in my eyes. "Good boy. Now, for recognizing the superiority of my big, strong, teenaged-girl muscles, I am going to give you what you really want." Then she reached behind my head with her free hand and grabbing my hair, pulled my face against hers and kissed me long and hard. She released me and slid her fingers under her skirt and pulled the hem up a little. My eyes widened as my gaze lowered. Monica's pussy was shaved clean. I groaned as I fought back the urge to shoot my load. "It's easier to be this way when you wear a lot of thongs and g-string bikinis during the summer," she explained, matter-of-factly. "I take it you like it." I only nodded. My ability to speech was suddenly gone. "And you like this?" Monica flexed her huge arms, her now 19" cannons exploding. Her legs, her quads and hamstrings swelled into etched blocks of oaken muscle splendour. Her abdomen rippled with steel cables. My mouth dropped open. "You want to fuck me? You want to feel my muscles, don't you?" she whispered. More nodding from me. "But you're not man enough. I'm so much stronger than you I have to be careful not to overdo it and hurt you. That limits my pleasure." She said, "Do you understand?" I nodded again. "No, you're not man enough to fuck me, but I am more than enough woman to fuck you. And do it whenever I want. Like now." Monica pushed me through the door to the boy's restroom and I tumbled inside. Monica then knocked me flat on my back and stood over my chest. She squeezed her breasts together and tugged at her erect nipples, clearly visible under the tight fabric. I gazed blankly up at the massive thighs and huge boobs which filled my whole field of vision. I knew she was going to dominate me sexually, the way she now dominated me physically. Monica could see my desperate internal struggle. She laughed, squatted down and opened the front of my pants. My tool shot out, and stood huge, and erect as a flagpole. Monica laughed again at the sight. Then slowly, very slowly, she squatted down further over me, and took my straining cock inside her. I struggled to retain control of myself. I tried desperately not to cum. I thought of icebergs, nuns, penguins; anything to take my mind off the tidal wave of sexual feelings that Monica seemed able to arouse in me. Monica saw my mental struggles intensify. Her grim laugh boomed out again. Then she raised her huge biceps, and flexed them hard. My eyes glazed over at the sight. My resolution weakened. Then she breathed in deeply, expanded her chest, and tensed her whole body. Her internal muscles squeezed and massaged my cock, up and down, harder and softer, with a power and a sensual skill I had never imagined. My resistance collapsed like a house of cards. My eyes glazed over even more. My mouth just hung open. I gasped and panted. Monica intensified her sexual engagement. She squeezed harder, and massaged even more powerfully and erotically. I started to jerk as if I had been galvanised. My eyes almost started out of my head as Monica's muscles brought me to the point of eruption. She held me there, totally at her will, while I begged and pleaded for release. Then Monica plunged down as fast and hard as she could on my tool. My eyes nearly bulged out of my head. She rubbed her clit vigorously, creating more shock waves. She began to moan aloud and ride my cock up and down as fast as she could. Her hard glutes slapped against my soft thighs as she rode me, up and down, back and forth. I erupted into a massive, volcanic orgasm. I thrashed and jerked convulsively. I tried to scream but only produced a faint sound. And then it happened; Monica climaxed. The force came from the center of her being and just exploding, a rumbling, roaring sensual climax that shook her body to the core. That was the orgasm she wanted and needed. Now she was satisfied. I opened my eyes as I felt the girl lifting off me. There was a popping sound as my cock head slipped out off Monica's tight snatch and I just collapsed. I lay limp and spent on the tile floor gasping for air. Monica grinned. "Ummhh, that was good....let's do it again sometime stud!" she rasped." In fact, meet me at the gym tomorrow!" She stood up, adjusted her skirt and left. The end.
