It's in the nature of the male by first timer I was on my knees again with my head between her thighs, my tongue softly lapping and nursing at her pussy thinking back to where it all started with me and her. Thinking how easily she had broken and trained me. Transforming me into her male bitch. God it seemed like years ago. I was a bull of a man back then, an amateur bodybuilder 250 pounds of bulging male muscle and she at the time was a skinny nerdy looking girl, a senior in high school with nerdy looking glasses, but behind those glasses was a controlling discipline mind with an IQ that made me look like an oyster compared, a student of human nature way beyond her years she easily manipulated me through my own peacock strutting male sexuality to where I am now with my face between her legs licking her pussy. We met at my gym. It was a Saturday afternoon the place was practically empty except for me and a few others as I worked out with 40 pound dumbbells looking at myself in a wall mirror as I pumped up my biceps I saw her reflection watching me from behind with a curious smile on her face. I knew sometimes women would come in just to see guys like me working out. Secretly fantasizing about what it would be like having sex with a male bodybuilder or even female bodybuilders depending on their taste so I gave her the show grunting out a few more curls than dropping the weights doing a double bicep pose in the mirror for her looking for her reaction in the reflection and there was, with her hands nervously adjusting her glasses and I chuckled to myself. But there was something about her, something different that drew me towards her. She seemed so young and petite that my balls involuntarily pulled up at the site of her with her penetrating blue eyes magnified behind those glasses. It was a type of knowing look on her face and a smile that said. "I could fuck those big balls right off of you"! To tell the truth It was kind of intimidating to me at the time which stirred strange feelings in me. I was a hundred times bigger and stronger than her but she seemed stronger in some strange way and my knees felt weak looking at her reflection until I turned towards her weakly going down to one knee while using a hand supporting myself on the bench next to me as she came over to me. "Hi my names Kathy. You're really strong. I'm doing a thesis on male bodybuilders and their psychological effects pertaining to females and other males for mating purposes. It's going to be a study about, you know, if big muscular stronger males like yourself are more sexually exploited by females opposed to the weaker ones. If you're interested in helping me? I'd be eternally grateful. Here's my name and address and number if you're interested okay. Call me". With that she turned and left walking out very coquettishly looking over her shoulder smiling making a motion with her hand a thumb and finger call me. What the fuck just happened? This little high school girl wants me to do what? Exploited by females! What the fuck is she talking about? All I knew was that my cock was ready to rip through my shorts thinking about her confident boldness. It was almost as though she was challenging me or something. Christ I'd fuck her in two. She'd be bleeding from her ass and pussy! I think it was just the way she turned away and left that infuriated me. Well after a few days I called the number she'd given me. It was her cell and she was in history class. So speaking softly she said. "Great! It'll have to be at your place alright no what I mean with my parents and everything they wouldn't understand a big stud like you showing up~giggling~for studies". She was charming and I gave her my address with us agreeing to meet at seven o'clock that night with me thinking maybe I'll just take it easy on her maybe. That day I worked out like never before. I was definitely pumped and ready to give her a taste of the real world of male bodybuilding, where we took what we wanted from a female. But I would be gentle with her at first until she begged for it then I'd split her in two with my cock. Thinking most likely she was still a virgin and picturing the blood on my cock and her screams of "no no no you're too big and strong you big fucking bastard" and grinning to myself. "Here's your thesis you nerdy little skinny tight twated bitch". I showered taking hours shaving my pubs especially my entire scrotum smooths I was always very proud of the size of my balls most male bodybuilders had small testicles because of the steroids, but I didn't do steroids and my balls were big really big I loved the feel of them and their weight hanging under my hard 10 inch cock thinking of the expression on her face when I answered the door laughing to myself. "She'll probably run away screaming." It was at that moment the doorbell rang and there she was as I opened the door naked. To my surprise she didn't flinch her eyes locked to my big dangling testicles and in a clinical tone she said. "I thought most male bodybuilders had little balls because of the steroids evidently you don't do steroids do you? This took me back as I stepped sideways letting her in with her still talking. "Female bodybuilders on steroids get really big clits, it's odd you would think male bodybuilders on steroids would make their balls bigger instead it makes them smaller. I'm glad you don't use them I've read studies where most females choose sexual partners by the size of their testicles ensuring fertilization opposed to the ones with smaller balls. She continued in this clinical analysis while taking her coat off almost ignoring me other than glancing back to my cock and balls. As her coat slipped over her shoulders revealing her tall slim naked body save for her long legs encased in black thigh high nylons and black six-inch heels turned spreading her legs wide facing me while placing her hands on her hips in a challenging manner saying. "I think we should get started don't you"? This wasn't the little high school girl I'd remembered. This was an aggressive female boldly challenging me and my mind went from this skinny little weak girl to one of awareness of my expose balls. I knew no matter how strong I was that if she was able to get to my balls I was finished and her eyes spoke the same language as my thoughts and like a rattlesnake her foot shot out and up into them slamming them up into my pelvis with the predictable results of me going down in pain. She calmly walked around me withering in pain reciting parts of her thesis. "Males are inherently weak no matter how strong they are because of their testicles they are vulnerable because of their maleness. They have testicles therefore why is it that females are considered subservient when obviously as I have just demonstrated its the males who are the weaker sex in comparison? So one would reason why? My thesis is based on this concept. But what I'm trying to demonstrate is that males inherently understand this but yet still denied it until it's crystal clear to them as it is to you now and to affirm my theory my final chapter will be on how I physically, a high school girl took a full grown male bodybuilder by the balls and broke him". She did that that night to me and I loved her for it. Disciplining me by my balls rendering me docile until I conceded to eating her pussy on command which I began eagerly looking forward to whenever I could. That was years ago. That's how we met and I'm still eating her pussy. She's in college now working on her doctorate in some type of human behavior thing sometimes brings home some of her female friends to demonstrate her theories to them. I'm still big and muscular and it amazes them when she orders me to get naked and down on all fours in front of them to demonstrate me to them and my submissiveness to her. Letting them handle my balls and sometimes letting them milk me like a male cow which is humiliating when the sperm from my balls gushes out my big long masculine teat with her telling them she considers my big hanging scrotum in reality as nothing more than cows udder explaining "It's just a big milk filled sac on them". The End.
