It was mid summer before my 15th birthday and right before the start of 8th grade. My father had forced me into playing basketball, but due to my height at the time- (5' 10") -I was put on a team with the high schoolers. Most of them were pretty cool about having a younger kid on the team and tried hard to boost my enthusiasm about the sport.
One guy in particular, let's call him James, was a 17, much taller than me at 6' 5", and had one of the greatest bodies I had ever seen on a guy. He tried incredibly hard to hone my skills and make me a better player. But my body type didn't really suit such a game.

You see, despite being tall, my body was a bit odd, considering I was going through pubrity. I was very slender from head to toe, hairless, but my chest was slightly puffy, to the point where it looked like I had small breasts. My shoulder length brown hair didn't help me look any more masculine either.

One day after practice James commanded me to stay longer and work on my re-bounds. I obliged and practiced for about half an hour more before he said it was time to hit the showers. James went to the mens locker room door, but said it was locked. Shrugging, He said that we could use the girl locker room since there was no female practices on that day.

I followed him into the girls locker room and stripped down, turning on one of the showers and rinsing the sweat out of my hair and off of my body. James walked in next to me, naked, with his cock semi-erect. There was something in his eyes that I couldn't really place.
As I was washing my stomach James slid his fingers across my neck. I shivered slightly at his touch. He told me it was time to dry off, but that he'd be back in a second.

As I rubbed my body clean of all water I head James rummaging through lockers. Which was quite odd considering his street clothes were in his bag.
He came around the corner holding one of the high school cheerleading uniforms. Sitting next to me, he cupped the back of my head in his large hands and guided my head to his bulbous dick. I resisted, telling him that I didn't want too, but his strenght was greater than mine, and soon my lips were curled around his thick rod.
My eyes were tearing up, I couldn't breath. But his cock tasted so good for some reason. Slightly salty with a light hint of soap from just washing.
He curled his fingers through my long hair and bobby my head up and down. I could feel my own penis stiffening up, which was a new sensation for me.

James pulled his cock from my mouth, drool stringing off from my lips and the throbbing head of his shaft.
He laid me down on the wooden bench we sat on and began to slip the skirt up my hairless legs. I could feel my face turn red with embarresment, but at the same time I was excited to wear girls clothes. I had always found them much more appealing than the boring options that guys had.
After the skirt was snug on my slender waist he pulled the crop-top shirt over my head, my puffy chest, mixed with padding in the shirt, made it look like I had very tiny breasts.

I looked at James and asked him what he was doing. He leaned down, kissed my exposed stomach, and told me that I was a girl now, and that men like to play with girls.

He ten lifted my legs up past my shoulders, my ass cheeks spreading apart to reveal my freshly cleaned hairless hole. Tears were beginning to fall down my face as he pulled a bottle out of his backpack and squirted to gooey fluid onto my ass and his cock.
He slowly began to push his dick against my hole, it was painful beyond words. This massive rod of skin trying to invade my virgin ass.
Eventually my muscles gave way and his cock slipped deep inside me as I let our a loud girlish scream.

My back arched with the sensations that were coming from inside me. My nubile cock as hard as it had ever been. James began to ram his cock farther inside me until his hips touched my butt. It hurt so bad but I couldn't help but moan at the sensations that were flowing through me.

He began to thrust his hips back and forth, my body jerking with every pump of his massive rod. His breath was hot on my neck and his body looked amazing. His abs were hard and chiseled and his chest looked so perfect, gleaming in sweat. I curled my arms around his neck and told him to do it faster. I'm not sure why. I just couldn't help myself.

James turned me over so I was on my hands and knees then inserted his dick into my hole once again. It felt deeper than before and I could feel it hit something deep inside me that sent a wave of excitement to my cock. I drooled erotically as ropes of white cum began to shoot out of my penis. Drenching my cheerleading skirt in creamy jizz.

I breathed heavily as James began to fuck me harder than before. My first ever orgasm seemed to ignite a fire inside of him, his muscular thighs slapping against my firm ass, making my cum drenched skirt flap back and forth, and my small chest bounce slightly with every thrust.
He let out a fierce grunt and then stiffened up. Suddenly I could feel liquid bursting into my sex hole as James moaned loudly. I whimpered slightly as my ass became even more full.

James pulled his cock out of me, cum dripping from my ass, and my long hair once again drenched in sweat.
He then put on his street clothes and left me alone in the girls locker room, laying on my back, panting on the bench like a dog.
My cock twitched once again, launching cum into the air, it splattering on my face in in my open mouth. It was creamy and luscious. I rolled off the bench, exhausted. Taking off the cheer uniform and looked at it fondly. After wiping the wet jizz off my body and putting on my street clothes, I proceeded to roll up the uniform and shove it into my backpack.

I walked out of the gymnasium, my ass sore, but somehow so satisfied.

I never saw James again. but upon learning what the word 'Gay' meant, I instantly knew that it applied to me. I had never been attracted to girls. All that could make my loins ache was the thought of James' muscular body ramming against mine, his cock shooting jizz deep inside me.
