Monica, part I. By Smog. My younger sister and some of her friends were planning a sleepover at our house this evening as our parents were out of town. She and her friend Monica had just finished preparing for the sleepover. "Well, I guess I'll go home and get my stuff!" Monica said. "Ok, then I'll see you later." My sister answered. "Ok! Will your brother be here tonight?" Monica asked with a sly smile. "He he ... ... sure, but he is in a bad mood these days, his girlfriend left him, I mean, if you were intending to hit on him." "I hope he likes the big Amazon type of body. Or I'll force him to like ... " Monica giggles and flexed her 20 inches biceps so that the sleeves of her sweatshirt almost tore, "so awesome!" She was getting wet by just thinking of rubbing Julie's brother's face on her larger than life muscles and breasts. Monica was out of control with happiness as she opened the front door to leave. As it happened I was just about to enter and was taken by surprise when the door suddenly flung open. "Ohh, hey there!" Monica beamed at me. "Ehhh, hey yourself," was my short answer. Monica eyed me up and down for a sec, blushing a little. "Looks like you have bulked up recently. Wow, you look huge!!" she continued. Gathering my senses, I found that I could just as well play along. "Well yeah, can't be a wimp and play college ball you know. Here, take a look at this" I said, as I pulled back the sleeves of my shirt and flexed both arms, with very sizable biceps rising up from them both."Go ahead, feel these babies!" I did not know that Monica was as muscular as she is. "Welllllll....." she cooed as she reached up and felt my quite big arms. ".....looks like you've been working out hard there, huh". "You bet, I bench 180 for reps, and squat close to 300" I bragged. "Say Monica, what are you doing here anyway, and where's my sister?" "Your sister is inside, and I have to go. See you around!" Monica sang out and went on her way. I went inside the house and headed for the kitchen where my sister was sitting, reading a book. "Hey sis, what's up?" I asked. "Not much. Me and the girls are having a sleepover here tonight." She said "Ohh ... well ... ok, I guess that's alright." I said and started to leave the kitchen. "Monica is coming over too." Julie then said. "That girl you said that had a crush on me? But she just left here." "Yep, that girl. Just to let you know." "Not interested." "Be gentle, she likes you. Besides, you don't have a girlfriend now anyways." "Tell her I'm not here." "Tsk, tsk, she knows you are here." "Tell her I'm sleeping then and won't be disturbed." "Of what are you afraid of? She'll not rape you ... I think ... I hope ... you know ... she is a bodybuilder, and I know you like your women muscley, isn't that right?" " Bah!" I just said and went for my room. Later in the afternoon, I heard the doorbell and Julie opened the front door. What I heard next made the shivers run down my spine of excitement. "Monica! Oh ... my ... GOD! You look even bigger than earlier today! You look fabulous! Look at those arms!" I heard my sister say loudly. I snoop at them through the small opening in the doorway; I could see Monica's big frame. I was sweating. I had lied to my sister. I knew that Monica was all over me to the point of obsession. Some time ago when Monica 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. I closed the door to my room and decided that I'd stay in here. My sister and her friends were sitting in our living room chatting away, having a good time and watching a movie, as I went through the living room on my way to the bathroom. I noticed Monica sitting in the couch with one leg up on her knee. She leaned forward slightly and rested her chin pensively on her right hand. The result was to bend her right arm, and the soft brown material of her shirt strained almost to the breaking point around by her massive upper arm. Just as I went by her, she raised her arms to adjust her ponytail while looking up at me with a little smile. My eyes almost bugged out of their sockets as I saw her biceps bulge at the motion. God, she was doing it deliberately, I thought, as I felt the inevitable reaction stir in my underwear. Back in my room again, I slumped on the couch just thinking about what I had just seen. My sister had said that Monica was into bodybuilding, but I never thought that she would have such muscles already. I just couldn't get it out of my mind which 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. I had always secretly loved the look of muscles on women ... ... well ... ... muscles like a fitness competitor, which my former girlfriend were proof off, but I never thought that huge muscles were for girls. I started to feel horny, so I went and turned on my computer to surf for some female muscle. The background showed a picture of my former girlfriend and I got a little lost in it so that I did not notice the door to my room being pushed open. "She's in pretty good shape, I see," came Monica's voice over my shoulder. I jumped, startled by her presence right behind me. "Pretty good?" I squeaked, still taking in Bridgette's, my former girlfriend, amazing musculature. "Well yeah," Monica replied, sliding past me while turning the chair I was in so that I faced her. "I mean, she's not quite as big as me, but she's got some definition." She walked over to my bed, my eyes following her uncertainly. Trying to recover my composure, I decided to act cool about it. "Well, yeah," I said casually. "That's actually one of the reasons I was attracted to her...I've always kind of, uh, been into girls with some muscle." "That's cool," Monica said with a smile. "I wish I could find a guy like that. Here, tell me how you like this." With an effortless motion, she flexed her arm into a massive bicep. "Wow," I couldn't stop myself from saying. I glanced uncomfortably at Bridgette's inert form, then back at Monica. She was smiling easily and holding her arm perfectly steady. Her bicep was the size of the ones I had seen on some male bodybuilders, certainly bigger than Bridgette's. It looked hard as granite, with an incredibly defined peak. "That's -- that's awesome, Monica. I bet there are plenty of guys who would..." "Nah, most guys see this and they never want to see me again. Especially if they feel how hard it actually is. Go ahead, try and squeeze it." As wrong as it felt, I couldn't resist. I put both hands around her flexed muscle and pushed against it. Just as I had suspected, it was as rigid as marble. I couldn't dent her massive muscle. "Wow," I said again. "And if I ever show a guy how strong this muscle is..." Monica raised her eyebrows mischievously. "Well, let's just say it comes as a bit of a shock. I know it looks impressive, but trust me...it's even stronger than it looks." I blinked at her, not sure what to say. She moved closer to me, breathing deeply. "Let me just get to the point." Her voice was getting softer now, full of promise. "If you like her muscles..." she jerked her head contemptuously at Bridgette still on my computer, "you'd LOVE mine." Gulping nervously, I stepped back and stammered, "Uh, well I admit they might look a little more impressive, but ... ... " Monica stepped closer to me again, smiling even broader. "Trust me. I can squeeze a lot out of these babies..." Now she flexed both arms for me. They exploded into monstrous peaks, her entire body seeming to swell right in front of him. "I think you'll be surprised. Watch this..." Looking me straight in the eye, she raised her right arm and flexed her huge bicep again and even though it was hidden under the fabric of her shirt, it looked huge and massive. My erection was back with a vengeance as I gaped at the young 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, she was only seventeen and her arm made mine look like a broomstick by comparison!" I thought. Monica saw the 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?" she said and looked down to my crotch where my member was clearly visible as it was hard as ever. "What??...No ... Yes ... Yes I do!" I stammered in a low voice. "I find you very sexy! Your muscles are so huge and sexy!" Slowly she raised her arms and flexed her biceps. They bulged up amazingly. She rolled up her sleeves and the biceps became visible. Huge and hard, veins visible in her arms, and ohh ... her biceps looked so muscular. "Feel them if you want" She said. She was unsurprisingly proud of her muscle bound physique 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 incredibly hard and muscular. Her arms were 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!" she whispered back, and I put my mouth against the fabric, stretching over the huge, hard bicep of her right arm. Monica flexed it even harder, which almost made me dizzy with excitement. "Lick them, now! I want you to lick them" Monica said. I had no option. I was not just attraction, it was powerful. Monica could have her way with me anytime, anywhere. It was her smell, her supernatural beauty, her size, the warmth; it was manipulating me like strings on a puppet. "I think I can totally do anything to you ... anything I can think of", she whispered, closing her eyes. My mouth was compressed against the hard muscle. "Monica ... " "I'm not hearing you, you have to speak louder. Much louder" "Monica!" "Scream my name, and I release you" "MONICAAAA!" I shouted in a beginning panic. She released me and I found myself thinking of what the other girls was doing. ""Uhhmm ... You see, is easy to make me happy, you only have to do what I ask ... " she purred, opened her eyes and gave me a quick, knowing smile. I step back a little, but Monica came forward to me. "Look at these breasts, don't be shy." She said in her girly voice. Reaching behind her back, she unzipped the long sleeved, tight top and peeled it off. I swallowed hard as it dropped to the floor, revealing a set of small, perky tits weirdly out of place on her mega-butch body. My first thought was she must have had a boob job, quickly replaced by my thinking why would she, she has great tits already. There was a sexy fullness to her breasts, or so it seemed to me. It looked like she had some invisible bra on designed to maximize her cleavage. To be continued ... ... ...
